webBrowser1 progressBar1 ERROR ... Seems like I am the only one

16y2.3mVisual Basic .NET

Hello there guys, The progress fine works partialy, but the debuger finds an error...

This is the error:

progressBar1.Value = (int)e.CurrentProgress;

Value of '-1' is not valid for 'Value'. 'Value' should be between 'minimum' and 'maximum'.

Parameter name: Value

This is the code:

[CODE]

private void webBrowser1_Progress(object sender, WebBrowserProgressChangedEventArgs e)

progressBar1.Maximum = (int)e.MaximumProgress;

progressBar1.Value = (int)e.CurrentProgress;

[/CODE]

Also I tried this:

[CODE]

progressBar1.Maximum = Convert.Toint32(e.MaximumProgress);

progressBar1.Value = Convert.Toint32(e.CurrentProgress);

[/CODE]

Any ideas??

Thank you !

I have attached project.zip above.

You guys can check the error if you want. I will give you guys the source..

the name of the program is Self Update:

There are 4 functions:

1) Download Latest Version of c# Generator (an open source software I started)
2) Launch C# Generator (will launch the exe of it.
3) Download Latest Sourcecode (will download latest version of the sourcecode (for the c# generator I am working on)

And finally:
4) Launch Main Thread

This is where I am having the trouble.. if you click on launch main thread, the webbrowser I am working on will open...
There is a progress bar INSIDE the webbrowser... that is the progress bar I am having trouble with...

I put a IF ELSE line there, but that is jst to try to resolve this issue... But it didn't work...

I compiled it with Visual Studio 2010... I hope you guys can help me by looking at my source code.
Thank you. Also, please ignore the progress bar in the Self Update window. That is a totaly different one.

Also... How do I change my profile picture?

This solved my problem :D
```
 private void webBrowser1_Progress(object sender, WebBrowserProgressChangedEventArgs e)
        {

            if (e.CurrentProgress == 0 || e.CurrentProgress == 90000000)
                {
                    //progressBar1.Value = 90000000;
                    progressBar1.Value = 0;
                    

                    progressBar1.Value = (int)e.CurrentProgress;
                    progressBar1.Value = 90000000;
                    
                }
                
                else
                {

                    return;
                    
                }
```

Put an check on value, if less than zero then stop PB or assign another value.

Thank you...

So... what does that mean? ...
I don't know what to do...

well... that whole thing brings zero errors...
BUT, when i click on debug, as soon as the website loads, the debugger points to it and gives me an error, which is the one I wrote before...

This error is what it says:

progressBar1.Value = (int)e.CurrentProgress;
Value of '-1' is not valid for 'Value'. 'Value' should be between 'minimum' and 'maximum'.
Parameter name: Value

The MaximumProgress should be set only once at the beginning of doing whatever the progress bar is showing progress for. The MaximumProgress is the value that indicates that the operation has finished.
