InfoPath Dev

I'm a newbie to InfoPath and am trying to write a custom Save event handler.

I went to Tools, Form Options, Open and Save, checked "Save using custom
code" and clicked the Edit button.

The VSTA IDE opened and a template FormEvents_Save method is there. In the
InternalStartup() code, there's a line to add this event handler to
EventManager.FormEvents.Save.

I wrote my custom code and saved it. I saved the form template.

When I attempt to fill out a form based on this template, I get the
following error when I try to save the form:

"Microsoft Office InfoPath"
"InfoPath cannot save the form.
The form definition (.xsf) file specifies that save functionality will be
defined in code, but the code does not define an OnSaveRequest event handler."

Should I be writing my own OnSaveRequest handler? If so, how? Why doesn't the IDE automatically create that method instead of creating FormEvents_Save() for me?

Something doesn't sound right about that scenario... The InfoPath 2003 OM uses OnSaveRequest, while the InfoPath 2007 OM uses FormEvents_Save

I followed the same basic instructions:

1. Create a new blank form.
2. Select Oepn and Save in Form Options
3. Select the custom coded check box and click Edit
4. In the generated code file I added the code MessageBox.Show("Hi"); and saved.
5. I previewed the form and pressed CTRL+S
6. My "Hi" dialog appeared, and after that the Save dialog.

Try with a new blank form and see if you get the same results.

Are you using a different machine, a different InfoPath to fill out the form than you are for creating the form?
