Button disappears when using LogMeIn to log into the computer #1
Description
It seems that if the form was opened from a Win7 computer, and then another user takes the computer using LogMeIn from a WinXP computer, the active button disappears.
If I close and re-open the form the button re-appears.
The reason for that, I think, is due the following code in ActiveButton.Initialize:
if (Win32.DwmIsCompositionEnabled || Application.RenderWithVisualStyles)
{
base.BackColor = Color.Transparent;
}
else
{
base.BackColor = Color.FromKnownColor(KnownColor.Control);
}
The check of Application.RenderWithVisualStyles will not give correct results if the OS style was changed during runtime (according to this blog entry: http://www.yortondotnet.com/2006/08/applicationrenderwithvisualstyles.html).
The solution for us was to always give the button BackColor = Color.FromKnownColor(KnownColor.Control);
