Display a dialog once my main form is showing?

[Grant Schenck]

I have a C# form application. Once my main window is showing I want to
pop-up a login type dialog. What event would I trap to affect this? I
tried handling the form load but the main form window is not yet visible
then.

Thanks!

Grant,

You will want to use the Activated event to handle this. First, you
have to define a flag in your class:

// Default to false, indicating that the form is not activated for the first
time.
private bool firstTimeActivation = true;

Then, you have to handle the Activated event:

// If the flag is true, then show your login form.
if (firstTimeActivation)
{
// Set the flag to false here. The reason for this is that when
// your login form is closed, this form will activate again, and
// this will be called again before you exit this block for the first
// time.
firstTimeActivation = !firstTimeActivation;

// Show your login form here.
}

Hope this helps.

There are many events which are fired while the form is getting loaded, painted:

Activated, GotFocus, LayOut.... Please consult MSDN for type Form and have a look at the Event section.

HTH, Metallikanz!

Thank you!

That did the trick.

Hi,

It does depend if you want to have the back window visible or not, if not
use Load ( the good thing of this one is that it fires only once ) if you
want it visible you could follow Nicholas's suggestion.

cheers,
