Screen capture with IE AxWebBrowser control and hidden Window

[Berry W]

Hi,

I'm trying to capture hidden window's data that is in IE's
AxSHDocVw.AxWeb Browser ActiveX control.

If Control and window are visible, code below works but if Control
and it's window is hidden e.g. emmedded in dll, code does not save
data as an picture. How should I handle this kind of situation?

How can I get data printed to file if AxWebBrowser is hidden and
in dll file?

Cheers,

public void CaptureWindow(A xSHDocVw.AxWebB rowser axWebBrowser1,
string fileName,
ImageFormat imageFormat)
{
// Handle to BrowserControl
IntPtr hwnd = axWebBrowser1.H andle;

// Get handle to Browser's ActiveX Window
int hdcSrc = User32.GetWindo wDC(hwnd.ToInt3 2()),
hdcDest = GDI32.CreateCom patibleDC(hdcSr c), // Creating memory device
context
hBitmap = GDI32.CreateCom patibleBitmap(h dcSrc, // Creating Bitmpat in
memory
axWebBrowser1.W idth, axWebBrowser1.H eight); // Width and Heigth of the
Browser's Window
// For creating color bitmap
GDI32.SelectObj ect(hdcDest,hBi tmap);
// Performs a bit-block transfer of the color data corresponding to a
rectangle of
// pixels from the specified source device context into a destination
device context
GDI32.BitBlt(hd cDest, 0, 0,
GDI32.GetDevice Caps(hdcSrc,8), // Width of destination rectangle
GDI32.GetDevice Caps(hdcSrc,10) , // Heigth of destination rectangle
hdcSrc,0,0,0x00 CC0020);

// Saving Bitmap as file. Format can be e.g. gif, jpeg, tiff etc.
SaveImage(hBitm ap, fileName, imageFormat);
// Releasing resources
User32.ReleaseD C(hwnd.ToInt32( ), hdcSrc);
GDI32.DeleteDC( hdcDest);
GDI32.DeleteObj ect(hBitmap);
}
