Crystal reports 11 RDC (COM API) displays printer dialog even when I tell it not to prompt
- by bdonlan
I'm using Crystal Reports 11's RDC (COM) API to print. My code looks like this:
HRESULT res = m_Report->SelectPrinter(b_driver, b_device, b_port);
if (FAILED(res)) return res;
// For these calls, the #import wrapper throws on error
m_Report->PutPrinterDuplex(dmDuplex);
m_Report->PutPaperSize(dmPaperSize);
m_Report->PutPaperSource((CRPaperSource)pdlg->GetDevMode()->dmDefaultSource);
if (m_Report->GetPaperOrientation() == crDefaultPaperOrientation)
m_Report->PutPaperOrientation(crPortrait);
VARIANT vfalse;
VariantInit(&vfalse);
vfalse.vt=VT_BOOL;
vfalse.boolVal=0;
res = m_Report->PrintOut(vfalse);
However, at the end of all this, crystal reports still shows its own printer selection dialog - but only for some reports, it seems. Why does crystal reports show a print dialog even when I pass false for promptUser? And how, then, can I suppress crystal reports' internal printer selection dialog and force it to use my values?
Edit: Whoops, CR11, not CR9.
Some further information:
The reports that work properly (ie, do not show the print dialog) are generated internally using the RDC API; we create a new report object, import subreports into it, then print the result. No problem there.
The reports that do not work properly (ie, force the print dialog to open) have been created with a previous version of crystal reports; however, opening and saving the report does not seem to help.
Sample reports in the Crystal Reports installation directory show the same problem.
I tried reproducing with VBScript; however, the result was that nothing was printed at all (no dialog, no nothing):
Set app = CreateObject("CrystalRuntime.Application.11")
Set report = app.OpenReport("C:\Program Files\Business Objects\Crystal Reports 11.5\Samples\en\Reports\General Business\Inventory Crosstab.rpt")
report.PrintOut(True)
rem Testing with a True parameter to force a print dialog - but no printout and nothing appears (no error either though)
