I have a dialog which is created dynamically and I have no problems with subclassing the CExtCombo box on it, the only problem is that I now want the CExtCombo to be owner drawn so I can use the multicolumn feature, but I can’t seem to get past the error. I have emailed you a sample, can you help?
Regards,
Eddie

It seems the problem hides somewhere in your code. In your project we created a simple CComboBox-derived class and it doesn’t work either. The error occurs in the MeasureItem method when we receive an incorrect value for the lpMIS->itemID property. Please note the problem is gone if we replace the CBS_OWNERDRAWFIXED style with CBS_OWNERDRAWVARIABLE.
