Print preview images

Hi,

I can't work out how to change the images in the print preview screen. I added a print preview button to the MoreAnchors sample and have attached the associated function below.
1. Can you tell me what I am doing wrong?
2. Is there any way of changing the icon for the print preview window?

Thanks

void CMoreAnchorsDlg::OnBnClickedPreview()
{
// background displays okay
fcx.LoadPicFromRes((long)AfxGetResourceHandle(),_T("IDR_IMAGE2"), _T("IMAGE"));
fcx.SetPicturePos(picFit);

Picture pic = fcx.GetPicture();
PrintOptions pOpt = fcx.GetPrintOptions();

// image for close is not changed
pOpt.SetPreviewTbarPicture(7,pic);
fcx.PreviewDiagram();
}

Hi,

It seems the toolbar control used in the preview window supports only images in .bmp format, and IDR_IMAGE2 is a .gif. If I remember this correctly, the color from the top-left pixel of the bitmap is set as transparent background by default.

I hope that helps,
Stoyan

Thanks Stoyan,

Got it working, it seems that the size was also critical. Needs to be 32x32.

I presume there is no easy way to change the icon for the print preview window.

It should be possible to change the icon by sending WM_SETICON message to the preview window. Use the OpenPreviewWindow method instead of PreviewDiagram to get the HWND handle of the preview window.

I hope that helps,
Stoyan

That worked, so I now have a new icon and toolbar images.

Thanks Stoyan
