    global variable

    Hi,

    I just wanted to be sure that the value of a global variable in VBA is lost when an error is produced. There is not way to solve this problem?? Then , it is not good to use this kind of variables??

    Thank you

    Re: global variable

    the variable may have nothing to do with the error,
    the value of the global variables are retained, you should use proper error handling
    vb Code:
    1. On Error GoTo errh
    2. vtest = "whynot"  'public global variable
    3. Err.Raise 99
    4. MsgBox "will not show"
    5. Exit Sub
    6. errh:
    7. vtest = vbNullString
    if you comment out the on error goto, excel will break, but the variable will still retain value

    i do my best to test code works before i post it, but sometimes am unable to do so for some reason, and usually say so if this is the case.
    Note code snippets posted are just that and do not include error handling that is required in real world applications, but avoid On Error Resume Next

    dim all variables as required as often i have done so elsewhere in my code but only posted the relevant part

    come back and mark your original post as resolved if your problem is fixed
