Changing target printer from WebBrowser Control...

Hi,

I have an MFC app that has a Dialog containing the Microsoft WebBrowser control.

Once I have navigated to the appropriate URL, I wish to initiate a 'Print' however, I wish to change the target printer programmatically beforehand and set it back afterwards.

I loacated some source on Microsoft's MSDN for a function called 'GetPrinterDevice' that returns the appropriate hDevMode and hDevNames to the required printer; see
http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com:80/support/kb/articles/Q166/1/29.asp&NoWebContent=1

I therefore have the following:

HGLOBAL hDevMode = NULL;
HGLOBAL hDevNames = NULL;
if (GetPrinterDevice(_T("MyPrinter"), &hDevNames, &hDevMode))
{
   const LECMDEXECOPT_DONTPROMPTUSER = 2;
   const IDM_PRINT = 6;
   AfxGetApp()->SelectPrinter(hDevNames, hDevMode);        // Default to MyPrinter
   TheDocument->ExecWB(IDM_PRINT, LECMDEXECOPT_DONTPROMPTUSER, 0, 0);
}
else
{
   AfxMessageBox(_T("Failed to select 'MyPrinter'."));
}

If I misspell the required printer, the AfxMessageBox pops up, so the function appears to be <almost> working, however, ExecWB still prints to the normal Windows Default printer!!!

Can anyone tell me where I'm going wrong???

Thanks,

James

Install Platform SDK or get latest winspool.h and use the APIs

   SetDefaultPrinter
   GetDefaultPrinter
in these APIs we can specify the Printer name directly

Now that's the sort of solution I like!

I'm currently downloading the SDK!  Umm, good old microsoft - almost 200MB !

Do you have a copy of the latest winspool.h file you could send me, or copy the relavant lines in a comment ?

Thanks for the help...
