PrinterSetup from Preview has no focus

Postby mcsh » Tue Feb 17, 2009 2:09 pm

situation: VpeControl embedded in C# Form
Code: Select all
vpeControl.ExternalPreview = false;
vpeControl.ToolBar = false;
vpeControl.PageScroller = false;
vpeControl.Rulers = false;


preview is shown with
Code: Select all
vpeControl.PreviewDoc(vpeControl.Left, vpeControl.Top, vpeControl.Right, vpeControl.Bottom, PreviewState.Normal);


own ToolStripBar with Buttons for Printing, Email, ...
when i call
Code: Select all
vpeControl.PrintDoc(true);

the PrinterSetup dialog is shown (and looks like active) but has no focus (no hottracking of buttons, etc), so i have to click 2x on Ok or Cancel (first click to activate the dialog, second click to press the button)
the same happens when i call
Code: Select all
vpeControl.SendKey(KeyFunction.Print);

or
Code: Select all
vpeControl.SetupPrinter(null, PrintDialogControl.Always | PrintDialogControl.Full);


but if i use
Code: Select all
vpeControl.SetupPrinter(null, PrintDialogControl.Always);

the simpler dialog is shown and has regular behavior with full focus and all.

any suggestions?

vpe version 4.0.4.5427

This seems to be related to the event handling of your toolbar. Try setting the focus onto the VPE control before calling SetupPrinter().

I have tried various ways and combinations, setting Focus to the VpeControl, the VpeControl.ParentForm, the containing Panel, using Framework/VpeControl
Code: Select all
.Focus();
, P/Invoke
Code: Select all
SetFocus(vpeControl.PreviewWindow.Handle;
, each with or without
Code: Select all
DoEvents();
before and/or after...

I really think it is a problem of vpe, because
Code: Select all
int result = vpeControl.SetupPrinter(null, PrintDialogControl.Always & ~PrintDialogControl.Full);
does work correctly, but
Code: Select all
int result = vpeControl.SetupPrinter(null, PrintDialogControl.Always | PrintDialogControl.Full);
does not work (both without any DoEvents() or anything else).

more: vpeControl.Focus(); returns false, but vpeControl.CanFocus is true

We checked our source code and you should rather blame Microsoft than us.

In both cases, i.e. with PrintDialogControl.Full or without, we are calling the common dialog API of Windows: PrintDlg(). The only difference is that we specify the flag PD_PRINTSETUP in one of both cases.

As a quick idea, a workaround could be that you post (not send) yourself a message when the toolbar button is clicked. When receiving the posted message, try calling SetupPrinter().

Please let me know if this helps.

yes, it seems like it's a M$ problem - see other topic for resolution
