Problem in taking screenshot of webpages

[phpfreak2007]

Hello,

I want screenshot of website by passing url. I used the DrawtoBitmap method of webbrowser but it is not working properly. It gives empty images. I want screenshot of websites which i passed in loop.

 arrayList arrURL; 
bool flagSC = true;
 
for(int i=0l i< url.length;i++)
{
if (flagSC == true)
{
webbrowser1.navigate(arrURL[i].ToString());
 
while (webBrowser1.ReadyState != WebBrowserReadyState.Complete)
{
Application.DoEvents();
}
}
else
{
i -= 1;
}
 
 
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{ 
flagSC = false;
Bitmap bitmap = new Bitmap(webBrowser1.Bounds.Width, webBrowser1.Bounds.Height);
webBrowser1.DrawToBitmap(bitmap, webBrowser1.Bounds);
bitmap = (Bitmap)bitmap.GetThumbnailImage(175, 128, null, IntPtr.Zero);
bitmap.Save(filePath);
flagSC = true;
bitmap.Dispose(); 
}
}
 
 

The above code gives blank images.

Thanks in advance.

I see in your for loop that you do a i++ but then at the end of the loop you take that one away again.
Any reason for this?

Edit: I just tried the DrawToBitmap method and it worked fine
More Edit: Seems after making one picture, the next one always draw empty...
And More Edit: Well my problem seemed to be that extra call were being made internally to things like "about:blank" and the. I solved it with something like this:

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            if (e.Url.ToString() == correctURL)
            {
                Bitmap bitmap = new Bitmap(webBrowser1.Bounds.Width, webBrowser1.Bounds.Height);
                webBrowser1.DrawToBitmap(bitmap, webBrowser1.Bounds);
                bitmap = (Bitmap)bitmap.GetThumbnailImage(175, 128, null, IntPtr.Zero);
                bitmap.Save(filePath);
                bitmap.Dispose();
            }
        }
 

Just remember to set correctURL to the URL you are trying to capture the picture of.
