I want a button click on my main form to trigger opening a configuration form for user config and then closing it and then automatically starting up a slideshow form to display photos. Below is the event handler for the button click on my main form. I am using the dialogresult of the config window (play slideshow or cancel) to open up the actual slideshow form. I know the slideshow form is running because I can step through the code to initialize it and the program doesn't go back to the main form and just keeps running until I stop debugging but my form10  is not visible. What am I doing wrong?
private void button1_Click(object sender, EventArgs e)
{
Form9 configForm = new Form9();
Int32 timeDelay = Convert.ToInt32(Form9.txtbox.Text);
DialogResult dR = configForm.ShowDialog();
if (dR == DialogResult.OK)
{
Boolean setAsDefault = Form9.setDefault;
Boolean loopSlideshow = Form9.loop;
ArrayList images = libraryManager.getSlideshow(listView1.SelectedItems[0].Tag);
Form10 slideshowForm = new Form10(images,timeDelay,loopSlideshow);
slideshowForm.ShowDialog();
}
}
<i></i>

Are you sure (dR == DialogResult.OK)?
Are you seting DialogResult = DialogResult.OK in Form9?

Yes, it is being set. And I am able to break on that part of the code..

I had the code to play the slideshow inside the form_load function which never let's the form actually load.duh. so now before it loads i initialize the picturebox image to the first item in the array list of images in my slideshow. now I have the slideshow starting on a click of the play button in my new form. and doing:
private void buttonplay_click(sender, e)
{
foreach(image x in arraylist)
{
picturebox1.image = (image)x;
thread.sleep(3000);
}
}
while it's loads, i see the original image. once i click play the form goes white and shows no more images. :S

doing a Thread.Sleep(...) in your GUI thread is going to hang up your GUI. try using a Timer that fires every 3000 milli-seconds to go to the next image

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.
|
|
|
|
|
then how does it change? what decides which value changes if any?
If only MySelf.Visible was more than just a getter...

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

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

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 would. (Where's the evil grin emoticon?)

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

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
|
|

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.
