End of form resize

[MCzajk]

How to determine if user has ended resizing form? I need to invoke
time-consuming operation after the form's size has changed. SizeChanded
event seems to be triggered more than once during resizing.

One way you can do this is to override the Form's WndProc method and look
for WM_EXITSIZEMOVE

private bool inSizing = false;
protected override void WndProc(ref System.Windows.Forms.Message m)
{
if(m.Msg == 0x214) // (WM_SIZING
inSizing = true;
if(m.Msg == 0x232 && inSizing) // WM_EXITSIZEMOVE
{
Console.WriteLine("sizing ended");
inSizing = false;
}
base.WndProc(ref m);
}
