System.ComponentModel.Win32Exception: The operation was canceled by the user System.Windows.Forms.Pr

[shan_chennai]

I have a print component that opens up a printpreviewdialog and paints
all the controls.

Now when i click the Print, after setting Microsoft Office Document
Image Writer as default printer, the Save As dialog for saving the mdi
file is opened. When i click on save, there is no problem. But when i
click on Cancel, i get a unhandled exception as shown below.

I am able to catch this exception in code when i run the solution from
VS .net. But the unhandled exception occurs when i run the .exe
directly.

The code i use is as follows..
PrintPreviewDialog oPrintPrevDialog = new PrintPreviewDialog();
oPrintPrevDialog.Document = _oPrintDocument;
oPrintPrevDialog.UseAntiAlias = true;
oPrintPrevDialog.ClientSize = new Size(800,600);
if(oSettings==null)
oSettings=new PrinterSettings();
oPrintPrevDialog.ShowDialog();


.....

private void _oPrintDocument_PrintPage..
//
}
oPrintDialog.PrinterSettings.FromPage = 1;
oPrintDialog.PrinterSettings.ToPage = iPageNumber;
//PrintRange.SomePages;
DialogResult oDialogRes = oPrintDialog.ShowDialog();
if (DialogResult.OK != oDialogRes)
return;


EXCEPTION MESSAGE IS

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.


Can any1 help?

Shan,

Unfortunately, this looks like a bug. Basically, when a user cancels
the dialog, it is interpreted as an error message (there is a value in
winerror.h, I believe for this).

In order to get around this, you will have to wrap the call to show the
print dialog in a try/catch block, and if you get this particular exception,
check the error code to see if it is the one that corresponds to a
cancelling of the dialog.

I'd also recommend that you file this bug at the product feedback center
(watch for line wrap):

http://lab.msdn.microsoft.com/productfeedback/default.aspx

Hope this helps.

But the try catch is already given ..

try

{
dialogresult ...showdialog();
..
}

catch..

The weird thing is that this DOES NOT happen when i call the print
dialog directly without invoking the printpreview dialog.
This happens only when the following steps are followed...
1. call printpreviewdialog
2. click on print
3, The save as dialog is open (as default printer is image printer and
it save the mdi)
4. Click on cancel.

and does not happen when

1. call printdialog
2, The save as dialog is open (as default printer is image printer and
it save the mdi)
3. Click on cancel.
