BuiltIn control ID 1874
Esteban Astudillo


This is weird.

I used the BuiltInControlScanner utility to look for the IDs I want to handle the OnClick event for. For the "New" button in the Explorer's Standard toolbar it returns ID 1874.

If I create a BuiltIn control using this value for the ID property I get the exception message included below when Outlook starts. If I change the ID to something else (say, 354 for "Reply") no errors at all.

I haven't tried to reproduce this in an isolated application but I thought you would like to know

I just noticed that the BuiltInControlScanner utility actually reports that the "New" button I was looking at (ID 1874) has an "Unsupported - 0x000D" message in the "Type" column.

I guess this is because I was trying to refer to the sub-menu control called "New" in the "Standard" toolbar, instead of the "Mail Message" button (ID 1757) under the Menu Bar / File / New menu option which is what I wanted in the first place. This ID 1757 doesn't raise the exception like the 1874 one.

I thought the info could help somebody else.. ;)

Hi Esteban.

The fact is that the control with ID = 1874 is not a button. So you can't handle the OnClick event of this control. Moreover some built-in controls don't allow to change their properties at all. That is why you get the error message.
