I'm trying to save the image of a webbrowser control. Not a particular
image being shown on the page, but rather the visible display of the
webbrowser. Using VS2005 I figured that maybe DrawToBitmap would work,
but it appears that the webbrowser doesn't implement it.

So I looked around and found that this code:

Dim g As Graphics
g.CopyFromScreen(Me.wb1.PointToScreen(New Point(0, 0)), New
Point(0, 0), wb1.Size)

should get the image into a graphics object. What I can't figure out
is how to get that into a bitmap that I can hang on to. This:

dim b as Bitmap = g.???

doesn't appear to be the correct approach; at least nothing works.

Is there some way to do this or am I going about it wrong? I can use
SnagIt or even PrintScreen to dump it into the clipboard so there must
be some way to get at it. Any help greatly appreciated.

dgk,

A image in a webpage (therefore as well in the webbrowser) has to be forever
an image (or Java, Flash program or whatever related for web) as an url.

Therefore working with bitmaps in a webbrowser is withouth any sense.

You have to set the picture (url) too an absolute place in the browser or
create first something as a table to fix it on its place.

I hope this helps,

Cor

Hi,

Dock the webbrowser control in a panel. Use the panels drawtobitmap
method.

Dim bmWb As New Bitmap(Panel1.Width, Panel1.Height)
Panel1.DrawToBitmap(bmWb, Panel1.ClientRectangle)

PictureBox2.Image = bmWb

The OP wants to create a screenshot of the page being shown in the
webbrowser control and save it to a bitmap, IMO.

That was clever but it doesn't work; all I get is a white screen. I
then tried getting rid of the panel and using the form, but I get the
whole form with a big white space where the webbrowser is. I guess
that's why I was having so much trouble doing it straight; the
webbrowser image is sort of outside the scope of the project.

It appears that this is not going to be trivial. Any other ideas?
