                this.Close();
        }
    }
}

This is suposed to animate... I can't figure out why it doesnt. I've done this before. Why isnt it animating this time ^^

where are you creating your timer?

[dahwan]

I created the timer in the designer. It's enabled with an interval of 10.

[dahwan]

Seems the timer isnt working at all =/
If all my code in the timer tick is

this.Text += "a";

The window title doesnt change at all.

Whats wrong with the timer? =O

Hi

Check, Whether time is enable or not,

Check after loading the form or at the time of loading form

That is because of this line of code:

this.Invalidate();

in your paint handler. Please try to debug your program and see what happens. In addition I think you have some bugs in your timer function. Review the whole program.

The bugs in the timer function doesnt matter It's not even started yet. I will keep that going after i've gotten the timer to work.
I removed Invalidate(), but it still isnt moving

[dahwan]

OK, i moved this.Invalidate() from the paint onverride to the Timer tick

Working =D

Thanks!
