100% CPU look, how to draw/redraw form?

[Olav Tollefsen]

I have a program which does a tight loop. When I invoke the winforms
application, I enter the loop and the user interface does not appear on the
screen. The user interface should only display some status counters on the
form.

How should I construct the application to draw the userinterface and update
the counters (DataGrid) when running in my tight loop?

Call Application.DoEvents as you go round the loop.

Put an Application.DoEvents In your loop..

bool doit = true
while (doit
{
Application.DoEvents()
..
..
doit = false


It also Depends on your design of your form relaunching your code..

If you do a DirectX 9.0 managed program you show the form so that you can process the events and still do
all the rendering Like follows: My FOrms that do heavy 3d rendering use a launch routine like this.

using (DesignForm designForm = new DesignForm()

designForm.MdiParent=this
designForm.Show()
// While the form is still valid, render and process message
while(designForm.Created

designForm.Render()
Application.DoEvents()

}
