BUG: Spy++ Causes Exception in Owner-Drawn Combo Box

MORE INFORMATION

In the sample used to produce this error, the owner-drawn combo box did not have the style CBS_HASSTRINGS. A 32-bit value was being passed to the combo box by way of CB_ADDSTRING. This appears to cause the exception when the Spy++ message logging is turned on.

This error did not occur in previous versions of Spy++.

Steps to Reproduce Error

1. Load the project of the OWNCOMBO sample as provided with Visual C++ 4.0.
2. On the Build menu, click Rebuild All to get a debug executable.
3. Start Owncombo.exe by pressing F5.
4. On the View menu, click Output in Visual C++ 4.0.
5. Start Spy++ and move its window as well as OWNCOMBO's window so that MSDEV's output window is visible.
6. In OWNCOMBO, on the Examples menu, click Owner Draw Combo Box.
7. In Spy++, on the Spy menu, click Find Window.
8. Use the Finder Tool, and drag it over the combo box in OWNCOMBO.
9. In Spy++, under Show, click Messages, and then click OK.
10. In OWNCOMBO, add a color to the combo box (either Red or Blue).
