Application in focus

[Alan T]

How do I make my application back to focus during it is processing I switch
to other application and back ?

During my application processing, I open another application, eg. notepad.
Then I select my application, my application screen is in white.

This isn't a focus issue, this is a matter of you doing all the
processing on the main UI thread.

Perform your processing on another thread, and leave the UI thread to
process messages, and you should have no problem switching back.

Hope this helps.

Alan,

You have in my idea more possibilities to that as
the method
http://msdn2.microsoft.com/en-us/library/system.windows.forms.control.focus.aspx

or the properties
TopLevel and TopMost be aware that those can be annoying so when you use
them you can set them to true and direct than to false.

I hope this helps,

Cor

What I want to do is I want to let the process finish first before the user
can select the main form.
During the process the cursor is in "wait" type.
I just want to make the main form appear normal except cannot select the
controls on the form.If the main form appears in white, the user may think
the system is hang.

This isn't a focus issue, this is a matter of you doing all the
processing on the main UI thread.

Perform your processing on another thread, and leave the UI thread to
process messages, and you should have no problem switching back.

Hope this helps.

Hi,

This is what I did to solve my problem:

Main Form:
private void tsMnRebuild_Click(object sender, EventArgs e)

{

Thread KeywordThread = new Thread(new ThreadStart(this.ExecuteRebuild));

KeywordThread.Start();

}

private void ExecuteRebuild()

{

.........

.........

}



I have a conern:

Is there any possibility to make the main form crash if something happen to
the thread ?
