Unrequested call of subroutine - bug ?

[petrbury]

I've found some oddnes . I have a button and few radiobuttons on my form. Radiobuttons are managed by AddEvent. It works fine, but command Button1.Enabled = False causes an unexpected call of sub, which is for Radiobutton event.
I've attached a simple example program. Every click on any Radiobutton increases a number on form (that's OK). Click on button calls Button1.Enabled = False and number on form will increase (which isn't OK).
Is there any way how to repair it ?
Thanks
Petr

This cures the problem, but doesn't explain it :sign0163:

Sub Button1_Click
   cnt = cnt - 1
   Button1.Enabled = False
End Sub

I guess it's because you are disabling the Button and because there are no other controls on the form the focus is returning to one of the radio buttons which is treating that as a click.

I fell into the same trap when I started with Basic4PPC. As previously mentioned; when focus shifts to a RadioButton, its Click event is fired.

Thank You very much, it works.
I've added Focus to different button before disabling that one and now it's OK.:icon_clap:
