could be a re-drawing issue. Instead of having 2 buttons, you could have
one button, and then change its caption. Similarly in the code you could
either maintain its state information, or strcmp the labels each time to see
which mode you're in.

Subject: RE: Dynamic UI
Hello...
I was trying my Hand on something like this.... I have
a 'Draw' button. When pressed, the related action
occurs and this button disappears and an Erase button
sprouts in.... similarly when this erase button is
pressed same things happen and it's hidden and the
Draw button come in. But then theres something very
funny.... If I simply press the buttons, the buttons
disappear and appear properly. But the problem is,
when I press the 'Draw' button and do some action on
the form and then I press the button, the 'Draw'
button doesnt disapppear from my Form. But yes, the
action is transferred and inspite of the Draw button
in the form, the work is done of the erase button.
..........
FrmHideObject (frmP, FrmGetObjectIndex (frmP, 1203)) ;
CtlHideControl(GetObjectPtr(NewDrawButton));
FrmShowObject (frmP, FrmGetObjectIndex (frmP, 1202)) ;
CtlShowControl (GetObjectPtr(NewEraseButton));
.......
So anybody can help me on this....
Thanx
Su
