Vba repeat character - how to settle
Is string function in VBA?
The String function fills a string with the specified character for specified number of times.
This article is about VBA string functions, we're going to do quite a bit with string functions because they are really useful and what I like to do is go through the code here first and look at it first, which is what you will notice here I have a variable declared to store a string I declared another variable to store the result of our string functions and a third variable here to restore a number that we'll see below in our string functions, this next line actually stores the string in memory , it's just some kind of random string here with a bunch of letters and numbers, etc., so that that's saved and the next line is our actual first string function. You will find that the leftfunction basically returns a value in the visual base of function should always just think that someone is always talking about a function returns a value and then we have to do something with that value, so the value in this Case assigned to the variable on the left.
At this point you will notice that this function has parentheses after the name of the function. Most of the functions always have parentheses, even if there is nothing in the parentheses, just like functions in Excel and these are the two arguments for the function that we pass in the string that we saved and then enter the number 3 again, so this is a pretty simple function that basically says the leftmost three characters will be returned. The next one just returns one character, the leftmost character, so it should return the a.
The right function is similar, of course, but returns the characters on the right side of the string, so let's say I want to get four characters back, and then here's another example of the saying Give you the last character in the string because it picks up the rightmost character The Mid function is a bit more interesting The Mid function lets you rip a piece from the middle of a string In so in this particular case we also want to start one character and return four characters stringsall start counting at the first position as one not zero don't do it if you have programmed in another language vbastarts counting at onealso this would be the second third fourth and fifth character of the string of this next example is similar to the one we just saw with mid, but it leaves out how many characters you want it basically says start it at character position 12 and just give me the rest of the string so it's kind of nice to forget part of a string on the right. You might want to spend a minute comparing this to the right function because the right function is a bit different in some ways, it captures characters from the right, the next funny that next function is very simple it just tells you how there are many characters in the string The in string function is very useful It allows us to peek inside a string and look for a substring, so in this case we're looking for the substring 5 6 7 in our original string and the first argument The one you see here indicates where to start. If you look, you can change that, so let's say you want to start looking at position 5, you would of course put a5 there and it would actually start at position 5.
The next one does a very similar thing, just looking for that - the next one also looks similar for the pound sign. If it doesn't find a substring, as in this case, there is no pound sign in our string, it returns the zero. Remember this is easy to remember and after all this last one just shows that we are looking for another string, this time we are looking for the string at the end Now I just want to show you what these things are returning.
What we're going to do is look at what these return when this actually goes, so here we have our string functions in our code and the very first notification returns the ABC, the three characters on the far left the next just gives the whole Characters on the left back The function on the right naturally returns the correct four characters, so that's the right one for most of the four characters and this next one of course only returns the rightmost character. Now we can take a piece from the middle, so we start at character position two and a length of four don't think that goes to position, because that's a length of four, the next one starts at character position twelve does not specify any length and takes effect simply the entire right side of the string starting at position 12 again contrary to the fact that the way the right works is quite different, and then finally we just grab the length of that string which is nineteen characters in string returns, in astring we're starting a substring so the five seven starts at position 7 in our substring the - or which - starts at position 12 and a substring the pound sign doesn't exist in the substring so we get a 0 back for that and finally we search after bob and bob is at position 17 in our substring is a string of 19 characters, so 17 is 18 and 19 die In the last three characters of this string, you should definitely enter this code and execute it and, as we have of course discussed many times before, you can execute it with the f8 key. The nice thing about the f8 key is that as you cycle through it, you can move your mouse pointer over the variable and see what the variable is taking place after this assignment, remember that the line highlighted in yellow has not yet been executed, so take note that the result here is the empty string as I haven't signed anything to it yet, but as soon as I leave this statement the result is ABC, then I execute the next statement and I get thea and I execute the next statement I get a bob and then I can get the next instruction I get the B and the middle is the BCD BCD II So again I highly recommend you put this code in here and play around with it, go through it and make sure you understand what these string functions do, thanks
How do I use a string function in VBA?
InStr and InStrRev are VBA functions used to search through strings for a substring. If the search string is found then the position(from the start of the check string) of the search string is returned. If the search string is not found then zero is returned. If either string is null then null is returned.
What's a string in VBA?
Advertisements. Strings are a sequence of characters, which can consist of either alphabets, numbers, special characters, or all of them. A variable is said to be a string if it is enclosed within double quotes ' '.
What is CHR 34 VBA?
CHR is the VBA function and returns the character from the ASCII table. For example, Chr(34) returns 34th character, which is the “ sign (double quotes).
Welcome to this YSL tutorial in this article we will explain how to create and use VBA add-ins in Microsoft Excel. We'll start the article with a brief explanation of what an add-in is and why you might want to create it in the first place, then show you how to start a new project to begin creating your add-in, and give you an example of a pretty simple function that you may want to include in the add-in itself once we have written the function. We're going to talk about how you can save the file as an add-in, and then how to make it available for future Excel workbooks, the final parts of the article explain how to protect your code from being changed by others, and how to do it Your add can be made available to other VBA projects as well by having a reference to it, so let's get started.
One of the most common reasons for creating a VBA add-in in Excel is that you have written a bunch of custom functions in a workbook and you want to make them available outside of the rkbook so for example in this particular file I have a function called long Written date format that formats my dates with an anice format. So when I choose from my intellisense list, when I put a formula in a cell that conforms to the long date format, it appears in the intellisense I can open some parentheses and open point the function arguments to a date, put my tighter brackets and press Press Enter. I get a nicely formatted date including the suffix after the number of the day of the month so that's great in this particular workbook, but if I wanted to use this feature outside of the workbook I can't if I create a brand new blank workbook by adding i press ctrl + n trying to use my long date function as you say is equivalent to long date format.
You can already see that it doesn't show up in the intellisense list. I can open up some parentheses and try to insert a date I will be using the Today function for simplicity, but when I enter this formula I get an error so it doesn't get the name of the function I am trying to use To solve this problem, we will show you in this article how you can create a function add-in that you can then distribute and make available to all of your future workbooks. To start creating our add-in we need a blank workbook in which we can write our function code, so I press Ctrl + n in Excel to create a new blank workbook, then I press Alt + F11, to start the visual basic editor what i will do first is rename the project we are going to write our functions in it can be very important for a later step in the process.
It's worth making sure at this point that your project has a unique meaningful descriptive name, so I'll name my wise owl functions. Project names follow the same naming conventions as form modules so you can't use spaces and most punctuation is not allowed so stick with text and numbers, what we can do then is add a module to the project for me to do that can. Right click on the project in the normal way and select Insert Module e I'll rename my module to Batesfunctions.
We can then start writing our functions in the module we have created now, since we have already produced a article on how to create functions in this series. I don't want to spend too much time sticking to just one feature here for demonstration and it's the example I showed you, well, you are at the beginning of the article. Just keep in mind that in the real world your adding features could include so many different modules, and as many different features as you want, you can always go back and add more features and modules that you add later.
To demonstrate this in this article we are going to create a function called Longdate Format and define a single parameter for that function which is I will be a date parameter, so I will say date to the format. I can format. Sometime we go and that will be a date data type and then after the brackets I will say this works ion returns a hit string, type in a couple of times and then indent a space so we need to do some things in this particular function do, we're going to concatenate several different parts to create our date format.
One of the parts of the date format will be the suffix that will be added the end of the day number, so the number of the day of the month, so the first second third, etc. So I'm going to use a variable to store these values in so I'll be say dim suffix as a string and then compute then thesuffix i will use a case statement so i will say select case and then i will use a function called de which gives me the number of the day of the month and there is a day in Date format and then 'I'll quit myselect before I start filling in the details, otherwise I'll forget later and essentially I'm going to test several different options here, if the case is 1 or 21 or 31 then I know that Result of mysuffix and variable or the value in my variable stored so X should be equal to sT, if the day of month is 2 or 22 then I know the suffix should be equal to nd un d is the case 3 or 23 then I know the suffix should be d for everything else I know the suffix has to be be th so that I can use a caseelse statement there and say suffix equal to th so that that correct suffix is generated. What I'm going to do now is put that in a longer day format, and I'll also return the results to the long date format function.
If I say long date format equal then I'll just use a space and an underscore to make this Line across multiple lines of code, and I'm going to use a formatting function that is already built into VBA datato format parameter and whatever value was passed to that parameter, and the first part of my date format is 40s which gives me the name of the day of the week Monday Tuesday etc and then another single D that gives me the number of the day of the month I can close the double quotes, close parentheses and then concatenate so I'll use another space underscore to continue on the next line I can concatenate to this suffix I'll use another ampersand and then a far eres space and the very last part of the date format is added to the name of the month and year, so I'll be using the formatting feature again. I'm going to format the date but this time I'm going to use a slightly different formatting code space to make sure I have a space after my suffix and then for MS the name of the date of the month name and then finally another space and for whom the four digit Year there I can double close go to this point and close around square brackets and that's the function that was created before we actually turn this into an add-in. A quick thing worth testing your function to make sure it works, so I'll do this with the Handy-Sofort-Wi.
When I go to the 'View' menu, I can select 'Immediate' or just Press Ctrl + G and in the immediate window I can type a question mark followed by any function that goes with VBAso since I defined my long date format function myintellisense so when I type a question mark followed by Ctrl + Space on the keyboard , I can look up my longdate format function in the intellisenselist which returns today's date and if I hit enter at the end of the line just to make sure it returns a properly formatted date, I'll look reasonable, let's do that Close immediate window. The next step is to convert this simple function in a module in a standard workbook into an add-in. To save the file as an add-in, we can either click the save button in the visualbasic editor or go back to Excel, go to the file menu and choose Save, as an alternative we can go back to Excel and just hit the F12 key on the keyboard and don't show the Save As dialog box.
Now the location doesn't matter. The most important thing to do is change the Save As Type option We're not trying to save an Excel workbook, but we're trying to save an Excel add-in that has the Excel extension on in newer ones Versions of Excel was asked. You can also save in legacy format.
If you're still working in an Office 2003, you can save an Excel Add-In, but we'll go to Savehouses in Excel am Add-In. So once we have chosen to have the file type directed to another location, it will be automatically redirected to the Add-Ins folder which is part of your roaming user profile. Now this is the best place to save your add-ins.
Default location Excel will look for add-ins when you try to load them, but you don't have to save them here. You can choose to save your file on a desktop or in a shared location. It doesn't matter where you save your file add-in just to demonstrate that I'll say I'll give my add-in a reasonable name I'll call it wise owl add-in it's not inventive, but it is reasonable and if it is then click the 'save' button my atom is now saved.
One thing you may notice is that the name of the workbook itself has not changed. It still keeps the original default name from Generic Book 6. It is the actual name when you save an add-in.
The workbook itself does not store all of the code that we wrote in the VBA project so we actually cannot discard this workbook together because we really don't need them. I go to the file menu and close it and when asked to save changes, 'I won't care, I won't be asked anyway. Now the next step is how to make your add-in available to each other workbook to tell Excel that we want to use our add-in in future workbooks that we need to manage the add-ins that Excel currently has is loads so that we can go to the file from the Options menu, go to the Add-Ins tab on the left, select from the drop-down list below to Manage Excel Add-ins and click then click the Go button to view a list of available add-ins.
Now there is a slightly shorter way to get this dialog box too if I just cancel it for now. When I go to the Developer tab there is an Add Ins button here but for now it is inactive because I have no workbooks open when I just create a brand new blank workbook by pressing Ctrl + n I can click the add-ins button here, now open this dialog box right away so it saves having to go through all of these menus, now we have our add-in in Default add-ins location saved as we were prompted, when we save my head we could already see this in the list, but I save my add-in to my desktop so I have to look for mine so I can click on click the Browse button. I can navigate to my desktop I can select the mywise owl add-in file and then click OK which will then be added to the list and will each si. loaded ngle time youopenCelso it will now be available for every new product you create when I hit OK to show that when I do Ctrl + TheseMi colon, I will put a date in a cell in this brand new blank workbook press.
This is a quick way to enter today's date, then when I type in the same date format, in this version of Excel in Excel 2013 we see it appear in the Intellisense list and then I can open the parentheses to select the cell with My date-closing parentheses and press Enter, I find that my function works in a new workbook just to prove that it's not just that particular workbook, even though I set the add-in to work in that workbook when I create a completely new blank blank Ctrl + n again I have book 8 now and if I put a different date and cell here I can press Ctrl + semicolon and it can go to another cell and say that it is a long date format. Select that cell around the brackets and hit Enter there so that the Atom is now available for every workbook you create, if I decide that I need to make changes to the way my adding works is too no problem, if i'm already working in a workbook in excel then my atom is currently loaded and i can see it with the visual basic editor so when i go to the developer tab and click the visual basic button that does I'll see, but besides the two projects I've just created for the new workbooks, I've also loaded mywise owl functions - itself loads in the background so the code is always available so I can make whatever changes I want . I could add a new function I could add a new module with additional functions and then I made those changes for as long as possible I selected something in this project.
I can hit the Save button up here and save the add-in so that if you decide to distribute your ad to other users that the users won't be able to make changes to your code, or even save any changes I made See your code, and you make these changes in the Visual Basic Editor when you right-click on your Wise Elf Functions project, or whatever you called your VP. A project that you can select to view the properties of it view project in the dialog box that appears there is a protection tab and you can lock the project from viewing and then assign a password. I'm going to type in a nice simple simple one and then click OK.
We then need to make sure that we have saved the file, so if we click on the add-in anywhere in the project and then hit the save button in the visualbasic editor, we can simply restart our add-in for these changes to take effect . By far the easiest way is to close the VB editor and then close Excel all together if I then just quickly open Excel again from the start menu and just start another brand new blank workbook. I'll see my add still available when I say the long date format is still there and it will still work a few too many with a lot of brackets, no mind there it is and when I then go to the Developer tab 'Looking in the Visual Basic Editor, I should find that my add-in is available here, but the project has collapsed and when I try to expand the project then I am asked for the password so that other users can use your add- Can't see in, but you can enter your password if you need to make any additional changes to it.
We saw how easy it is to make our add-in available to other workbooks.We want to use the functions in our add-in in other VBA projects, this is a little trickier.I opened a new project here with a new workbook and i can insert a module into this project the usual way i won't bother changing it to name and i am writing a quick simple subroutine here called test which i know is not a very inventive name but please forgive me for just trying to display a message box here showing a nicely formatted version of today's date I would love to use my long date format to do this when I hit Ctrl + Space to open my intellisense list I will unfortunately not be able to access my long date format function.
I can open some parentheses and try indenting the date function just like but as soon as I try to run this subroutine I will find that the VP editor does not recognize the name of the function I am trying to use. The simple reason for this is that this VBA project currently has no concept that our add-in project even exists. To make this aware that the add-in function exists or the in project exists, we will become one Set reference to this project.
We can do this from the Tools menu and the 'References' option there. This is why you gave your original add-in project a meaningful name at the beginning of this section. So if we take a look at our functions, the name of our VBA project should we notice that there is a corresponding element here for our add-in.
When I tick the box, we set the reference toour add-in file and its original location, then when I hit OK and then try again from the cheapest end, try the subroutine this time so it doesn't is too much more complicated. It's just that extra step to make your add-ins available to other VBA projects.You need to select tool references and set a reference to your add-in project.If you enjoyed this training article, you can find many more online training resources at ww-whyZelko UK
How to create a string of repeating characters in VBA?
The Replicate () function will generate a string of repeating characters. This example will produce a string of 10 dashes: Visual FoxPro also has functions that will pad a string to a given length. The PadL (), PadR () and PadC () will add spaces or characters to an existing string and leave it left, right, or centre-aligned within a longer string.
Is there a VB function to repeat a series of characters?
That second argument can be the character itself, as shown above, or it can be the characters ASCII value instead... There is no VB function available to repeat a series of characters multiple times, but you can use String function coupled with the Replace function to accomplish it....
Which is function returns a string of repeated characters?
This function returns a String made up of repeated characters. The character that makes up the string is the first character in the Character argument, and it is duplicated Number number of times. Returns a string or object consisting of the specified character repeated the specified number of times. Required. Integer expression.
How many times does the VBA string function return?
The String function only uses the first character of a supplied String and so, in this case also, the function returns the character 'a' repeated 10 times. If you supply a negative Number argument to the VBA String function, you will get the error:
