// @ex Here's how to use this control in a dialog |
// 1. Include CBitmapPickerCombo.cpp and CBitmapPickerCombo.h in your project
// 2. In the resource editor create a regular combobox with at least the 
//    following styles: DropList, OwnerDraw Variable, Has Strings 
// 3. Create a control member variable for the combobox in VC's classwizard
// 4. Replace CComboBox with CBitmapPickerCombo in your dialog's .h file
// 5. In OnInitDialog use the AddBitmap or InsertBitmap member functions
//    to add bitmaps (and strings) to the combobox
