Question

So today s problem is getting me mad because that should be easy and i can not find the answer    How to declare a public array in VBA   I m using an array with the letters A  B  C     because i m working with Excel cells  and i don t want to declare it in every function i create  right   I ve tried to look on the web first and i read that you have to declare it in a different module  so that s what i ve done    Public colHeader As String colHeader   Array  A    B    C    D    E    F    G    H    I    J    K    L     But Visual Basic doesn t like it     So what shall i do    Thank s a lot     Edit   the problem is more about asigning values to the array than to declare it

Well  basically what I found is that you can declare the array  but when you set it vba shows you an error   So I put an special sub to declare global variables and arrays  something like   Global example 10  As Variant  Sub set values    example 1    1 example 2    1 example 3    1 example 4    1 example 5    1 example 6    1 example 7    1 example 8    1 example 9    1 example 10    1  End Sub   And whenever I want to use the array  I call the sub first  just in case  call set values  Msgbox example 5    Perhaps is not the most correct way  but I hope it works for you

You are using the wrong type  The Array      function returns a Variant  not a String   Thus  in the Declaration section of your module  it does not need to be a different module    you define  Public colHeader As Variant   and somewhere at the beginning of your program code  for example  in the Workbook Open event  you initialize it with  colHeader   Array  A    B    C    D    E    F    G    H    I    J    K    L     Another  simple  alternative would be to create a function that returns the array  e g  something like  Public Function GetHeaders   As Variant     GetHeaders   Array  A    B    C    D    E    F    G    H    I    J    K    L   End Function   This has the advantage that you do not need to initialize the global variable and the drawback that the array is created again on every function call

This worked for me  seems to work as global    Dim savePos 2 To 8  As Integer   And can call it from every sub  for example getting first element    MsgBox  savePos 2

Try this   Dim colHeader 12  colHeader     A    B    C    D    E    F    G    H    I    J    K    L     Unfortunately the code found online was VB NET not VBA
