Commenting code is an art form! This series of blogs explains why, how and when to comment in VBA.
Dear Andrew et al I have been studying and enjoying your amazing videos for quite a while a while. I managed to (1). Create a payment system with vba code with application inputbox (2). I created vba code to review the payment system in (1) to ensure accuracy of date entry.
The first problem I have now is that when I run the review code and if no change was made to the payment entry in (2), the original entry are being changed to either '£0' or 'false' I have been scouting through the internet for solution to no avail. Please what vba code to write so that the original entry is not changed if no change is made at the review code stage?
The second problem I have is with the following code:
ActiveCell.Value = PaymentAddress
Worksheets("PCN Form").Select
For Each Cell In Selection
Do
If ActiveCell = "" Then Exit Do
Cell.Value = UCase(Cell.Value)
On Error GoTo 0
Exit Sub
Loop
Next Cell
Application.DisplayAlerts = True
Application.ScreenUpdating = True
On Error GoTo 0
End Sub
When I place this code at the begining or middle or procedure, it stops after running without completing other procedures. I have therefore being constrained to put this procedure at the end. Otherwise, would prefer to bring it in the middle.
The third problem I have is how to write a vba code to validate a payment_reference to contain alphanumeric and also not more than 10 digits.
Can't thank you enough for your amazing videos. Keep us tuned! Kindest regards Zeno
Hi Zeno,
Thanks for your comments and questions. Your first question is difficult to answer as you haven't shown the code that you've written. I'd suggest using an IF statement to check whether the new value is different to the old value and only write changes to the cell if that is true.
For your second question I have to admit that it's quite difficult to work out what it is you're trying to do! Some of the code you've written, particularly the Do Loop and Exit Sub statements, appear to be unnecessary. If you're simply trying to change the value of a single cell to upper case text then the only line that you need would be something like this:
ActiveCell.Value = UCase(ActiveCell.Value)
For your third question you'll need to know a little about manipulating strings. Fortunately, we have a few videos on this topic. You may find these ones useful:
