I have this in my Form1.Designer.cs code.
this.pictureBox1.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom)
| System.Windows.Forms.AnchorStyles.Left)
| System.Windows.Forms.AnchorStyles.Right)));
this.pictureBox1.BackColor = System.Drawing.SystemColors.ButtonFace;
this.pictureBox1.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle;
this.pictureBox1.ImageLocation = "";
this.pictureBox1.Location = new System.Drawing.Point(13, 71);
this.pictureBox1.Name = "pictureBox1";
this.pictureBox1.Size = new System.Drawing.Size(1303, 701);
this.pictureBox1.TabIndex = 3;
this.pictureBox1.TabStop = false;
this.pictureBox1.LoadProgressChanged +=new System.ComponentModel.ProgressChangedEventHandler(pictureBox1_LoadProgressChanged);
Is that where it needs to be?

your code are exactly the same as mine, still, works fine, the image loads pretty fast, so the progressbar moves fast, but stops at 100% you said that a breakpoint don't helped, what was the behavior? the method isn't being called? the image isn't loading?

The break gives me this:
ImageViewer.exe!ImageViewer.Form1.pictureBox1_LoadProgressChanged(object sender, System.ComponentModel.ProgressChangedEventArgs e) Line 71 + 0x5 bytes C#
ImageViewer.exe!ImageViewer.Program.Main() Line 18 + 0x1d bytes C#
I'm using 2010 Express of visual studio would that have anything to do with it?

And everything works just fine except I do not see the progress bar fill up at all and once the image is done loading completely I still dont see any green.
|
|
|
|
|
And a breakpoint didn't come up with much help.

Did you set the Maximum on the progress bar to be something sensible?
|
|
|
|
|
I have the Min set to 0 and the Max set to 100.

OK, let's break this code down line by line
1) Open the file, create a bitmap and set as the picturebox image
2) Set size mode
3) tell picturebox that future image loading will be async
4) Do async load from the file, this is now reloading
So you are loading the image twice.
I think all you need is
pictureBox1.WaitOnLoad = false;
pictureBox1.LoadAsync(open.FileName);

Thanks for catching that for me. I've made that corrections but the progress bar still does nothing.

So how long is it taking to load the image?? The ProgressChange event if only fired every once in a while, not on every byte that's loaded. It may not even be fired at 100% either.
There's a second event that you can handle to get notified that the image is completely loaded. That's the LoadCompleted event. When this one is raised, you can set your progress bar to 100% and consider the operation done.

It's taking a good 10 to 12 seconds to open.

I need help with an SDK to develop an application that will work with the built in camera or any external camera. The camera should be able to take snapshots.. This application will of course be used on windows and will be programmed with C#..

What part of the app do you need help with? Please indicate what you've tried and ask a more specific question if possible. This will allow us to help you better.

Did you try to search this site? We got a lot of articles on webcam's, and most of them are in managed code.

I need to be able to use my c# written code to access my webcam(in-built). The one i got from this site isn't what I wanted. This application should be with winforms not wpf

What prevents you from embedding the WPF window containing the MediaElement in your WinForms app?

Hello!
I'm trying to create a Regex so it would work same to String.Contains. In general I just create Regex from the string, but there are a lot of problems here: the string may contain +, * and other characters so Regex throws exception as it does not likes this.
I assume that Rexeg.IsMatch works faster than String.Contains so I'd like to use it.
Do you know how to work this around? I could replace all the escape characters in my string to \+. Maybe there is something better?
Thanks.
