Exception when cancelling InsertPages

[akurian]

Hi,

I am using the following code in my toolbar button handler to allow the user to use your InsertPages UI:

Code: Select all

object dataIn = null, dataOut = null;
viewer.DoVerb("Documents[0]", "InsertPages", dataIn, out dataOut, 0);

This works fine except for generating a COMException when the user clicks Cancel. Am I doing something wrong? Do I need to call this via BeginInvoke?

Hi akurian.

This works fine except for generating a COMException when the user clicks Cancel.

Please wrap each call of DoVerb(and any other our method) into try/except brackets. Because when user canceled the dialog then DoVerb returns the 'ERROR_USER_CANCEL' error-code and standard COM-stub generates an exception on that.
Maybe in your project compilation settings you are able to turn off the generating COM-exceptions for returned error-codes..
