Hi,
I found the following code in a FAQ about the datagridview.
But I am having a hard time translating it to VB, so I would like to ask via
here for someone more experienced to translate this code to VB.
When I can read it in VB I want to replace everything about the image into a
button.
Thanks in advance!
Eric.
