Timer

bar3000

Hi, I would like to excute a command after a certain period of time, for instance 1 sec. For Example: pictureBox78.Location = new System.Drawing.Point(460, 360); 1 sec interval pictureBox78.Location = new System.Drawing.Point(560, 360); 1 sec interval pictureBox78.Location = new System.Drawing.Point(660, 360); 1 sec interval pictureBox78.Location = new System.Drawing.Point(760, 360); and so on... Thanks in Advance:)

OK, so what's stopping you from dropping a Timer on the form and handling it's Tick event?? In your Tick handler code, just look at the current Location.X parameter and add 100 to it.

I should have mentioned the fact that the picturebox may change and it does not necessarily change it's x coordinate by a constant value. It may also changes its y value.

I'd use a System.Timers.Timer, but that's just me.

then how does it change? what decides which value changes if any?

If only MySelf.Visible was more than just a getter... A person can produce over 5 times there own body weight in excrement each year... please re-read your questions before posting

So?? The concept is still the same. You're just chaning the math that you have to do inside the Tick event.

Intresting, but I'd be delighted if you could give me some more detailed code because I am a real noob in C#. Thank you:)

And as such, I would be doing you a disservice if I provided you with code; read the documentation and experiment, you'll learn more.

I would definitely use a Windows.Forms.Timer since that one ticks on the GUI thread, hence the tick handler can manipulate all Controls directly without needing any Invoke stuff. :)

Yeah, but since he's so new at this, I didn't want to throw the control cross-threading problem into his already existant confusion.

I lost you guys... But I'll try to find some book about it. Thanks anyway:)

Luc Pattyn

Yep. use a Windows.Forms.Timer, but before you do read up on everything you plan on using. A book is always a good start. :)

If you just want an interval, System.Threading.Thread.Sleep() should do the job.

Yeah, but the change in location requires a WM_PAINT message to go through the pump, which youre suggestion just halted for x milliseconds, preventing the message from being processed and the form being repainted.

Didn't know that. Maybe you have a command for refreshing the form?

Regards, Leonardo Muzzi

Dave Kreskowiak

Yeah, it's Invalidate, which generates a new WM_PAINT event for the entire form. Same problem. If the UI thread is blocked (sleep), the form doesn't get painted.
