Sub Testing() Dim userInput As String userInput = InputBox("What is decimal 4094 in hex?") If UCase(userInput) = UCase("ffe") Then Debug.Print "You have correctly written " + userInput + "!" End If End Sub |
Yup, it is a bit ugly, using UCase to compare all the time, between small letter text and big letter text. So, if you…
VBA – Get Substring Between 2 Substrings – Locate value of Nth XML
Getting N-th string between two substrings might sound a bad idea, until you do not need it. And with VBA, you better have something prepared. So, imagine the following XML (from this article here):
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |

VBA – Ubound of Multidimensional Array or How to Get What We Need?
Transforming Range to Array in VBA is actually a one liner – we take the range and we assign it to a variant:
|
1 2 3 4 5 |
Dim myRange As Range Set myRange = Range("a1").CurrentRegion Dim myArray As Variant myArray = myRange |
The “strange” part is that the array is converted to 2-dimensional array after this: and working…
VBA and Python – Intersection of dictionaries
Intersection of dictionary (or of any two lists) is a list with elements, that are present in both other lists. Thus, if we have the following 3 dictionaries in Python:
|
1 2 3 |
dict_a = dict([('aa', 4139), ('bb', 4127), ('cc', 4098)]) dict_b = dict(aa=4139, bb=4127, ee=4098) dict_c = {'aa':12, 'bb':13, 'dd':23} |
Then, an intersection of their keys will contain only…

VBA – Folders and Files Functions
Check if folder is empty:
|
1 2 3 |
Public Function FolderIsEmpty(myPath As String) As Boolean FolderIsEmpty = CBool(Dir(myPath & "*.*") = "") End Function |
Delete all files in a folder:
|
1 2 3 |
Public Sub DeleteAllFiles(path As String) Kill path & "*.*" End Sub |
Create text file in a given path with text:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
Public Sub CreateTextFile(path As String, fileName As String, text As String) Dim fso As Object Dim file As Object Set fso = CreateObject("Scripting.FileSystemObject") Set file = fso.CreateTextFile(path & fileName, True) file.WriteLine text file.Close End Sub |
All together:
|
1 2 3 4 5 6 7 8 9 10 11 |
Sub Main() Dim path As String path = "C:\Users\Username\Desktop\New folder\" CreateTextFile path, "to_delete.txt", "some text inside the file" If Not FolderIsEmpty(path) Then DeleteAllFiles path End If End Sub |
