Getting the last row of a given column in Excel with a formula or with VBA is quite a trivial task. It is explained here quite well 🙂 However, when we come to C#, the only “trick” that is provided…
Finding the biggest square of specific units in a given matrix of these units is a standard dynamic programming problem. The examples in Google for it are above 18 million, thus I would simply show how it is done with…
Copying an object in VBA to a new object is somehow tough. If you use Set foo = bar then, both foo and bar would be pointing to the same address in the heap. And if you change the properties of one, you would automatically…
The environmental variables are a dynamic-named values that can affect the way running processes will behave on a computer. With other words, if you want to see them in your PC, simply open the command prompt and write the nice word…

Adding shapes to a range in VBA with Excel is actually a trivial task, if you are aware of the Shapes.AddShape method. It has 5 parameters, 4 of which could be pretty easily remapped to the parameters of the range:…
Animation consists of some pictures. In general, there are about 24 pictures per second, in order to do the “magic”. This could be easily automated with Excel, using Application.Wait (Now + #12:00:01 AM#), if we agree to make it a bit old-fashioned, with 1 picture…
Automation of Excel is actually pretty interesting task. VBA is indeed the best built-in tool for this and although there is a lot of “hate” towards it it really deserves to be taken into account seriously, at least for small daily…
Writing for RegEx in VBA is sometimes a good idea and sometimes a bad idea. Anyway, if you need to write one, you better be careful. These are the RegEx articles in VBA in VitoshAcademy so far: https://www.vitoshacademy.com/vba-regex-in-excel-part-2/ https://www.vitoshacademy.com/vba-regex-in-excel/ So,…
VBA is extremely underestimated programming language. I have always been thinking that there are almost no real #VBA developers, because the “real” developers do not want to do some meaningless “macro” stuff and the people who work with #VBA are…
Gmail has the option to revert a message for about 10 seconds after you have sent it: Well, Outlook with VBA can do similar things, if you are willing to program it a bit with VBA. Let’s say that you…
Getting the last row of a given column in Excel is easily done with a User-Defined Function in VBA:
|
1 2 3 4 5 |
Function lastRow(wsName As String, Optional columnToCheck As Long = 1) As Long Dim ws As Worksheet Set ws = Worksheets(wsName) lastRow = ws.Cells(ws.Rows.Count, columnToCheck).End(xlUp).Row End Function |
There are two other formulas, which would get the last used cell in a given row, depending on whether it…
Sometimes, but only sometimes, someone needs to handle specific VBA errors and to avoid them. Or to ignore them. Or anything like this. Let’s say, you want to avoid error number 91, because you think that it is a case…
Calling the stack dialog box in VBA is actually a very useful feature of the VBA Editor. This is what the Microsoft documentation says about it: Displays a list of currently active procedure calls during break mode. When executing code…
Sometimes, you may need to scrape some structured data from the internet with Excel. Honestly, Excel. Honestly, Excel should be your last weapon of choice there, as far as it is really not a web-scraping software. Still, it is quite…
=VLOOKUP and =INDEX(MATCH(),MATCH())Â are well known formulas, if you need to get some value corresponding to another value from a specific column. The problem comes, when you are having more than one column or row, and you need to locate the…
After the article here for VBA – Select a Single Node XML now I am writing an update from it, which shows how to loop through all the nodes that we are interested in and get data from them. The XML is…
So, the idea is the following –Â imagine that you have an NxN range, which should be filled out with consecutive numbers. Thus, if the range is 6×6, you start filling the numbers normally and once you reach the 6.…
Formatting a substring of a string in an Excel Cell is actually quite a challenging task. There are two ways to do it – select part of the substring that you wish to format and change its color. Then make…
Changing tab color of Excel is somehow useful. With VBA, it is easily programmed, as far as one can use the macro recorder to see the correct way to do it. However, if you need to change the color of…
In this article I will simply use the code from my first guest author Mathieu, to build up some small working solution, that uses parameters: So, the two classes, provided by Mathieu are here as well  GitHub, named AdoValueConventer.cls and SqlCommand.cls.…
Selecting Python for a “weapon” of choice has many positive points, which I am not going to describe now. Still, if you want to run python code with the help of VBA and the Shell through the CommandPrompt of Windows,…
Selecting multiple cells in Excel through VBA may be quite a difficult task. Although, using Select is not always a good practice, sometimes it should be done. To generate some random values, let’s run the following:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
Public Sub FullMe() Dim myCell As Range Dim myRange As Range Dim cnt As Long Set myRange = Range("A1:F20") For Each myCell In myRange myCell = cnt If cnt = 6 Then cnt = 1 cnt = cnt + 1 Next myCell End Sub |
After this, we have…
Excel and VBA are a powerful tool for simulation. The idea is to simulate dice throwing and to keep the best N throws as our score. Other model variables are Times I roll, which stands for how many times do…
Working with Python and Excel together is really fun for a VBA Developer! It somehow shows you what all these years of coding with VBA have taught you! Today, I was thinking how to implement the .Find()Â method of searching in…
The XlsxWriter library of Python is a nice gem for a VBA developer – you would be really interested to see the problems a Python developer should be facing, just to achieve a simple part Excel automatization. Still, these are…
Markov model is a a stochastic model describing a sequence of possible events in which the probability of each event depends only on the state attained in the previous event. Wikipedia This is a good introduction video for the Markov…
Add comments in Excel with VBA
Adding comments with VBA is somehow quite a trivial task, if you already have the text of the comment and you are allowed to delete the comment if it is present. In general, the only difficult part is the check,…
