.Check is what you need.
.Check = 1 - the checkbox is "checked"
.Check = 0 - the checkbox is not "checked"
Sorry, but it doesn't work! That's the reason why I post this thread.
Whatever the Checkbox is shown (Checked or not Checked), the command: "MsgBox cb_cop_aussen.Check" always returns 0.
Okay. I created a new form. There it does work! So I think some bad binary data in the .frm file was a possible reason for that.
Yesterday I noticed a few bugs. For example when I try to copy and paste a line of my code, the order of the whole script was messed up.
