Hi,

I have a class which is derived from CXTPControlComboBox. I want to implement PreTranslateMessage in the combo box code. How I can do? Is it possible? Please give me the solution. If it is not possible what is the alternate way to implement that? Please help.

Hi,

CXTPControlComboBox is not CWnd derived class and doesn't have PreTranslateMessage. What message you need catch in PreTranslateMessage?

Hi,

The problem is SetCurSel() is automatically calling the OnSelChanged() method,but I have some settings in the OnSelChanged(). So whenever if I call SetCurSel() the code in the OnSelChanged is running. I do not want the SetCurSel to call the OnSelChanged() Method. How? Please Help.

Hi,

Don't see how PreTranslateMessage can help here...

Anyway. you can add some BOOL variable in your derived class and before call SetCurSel set it to true/ after call set to FALSE and check this variable in OnSelChanged.

Hi,

Thanks. My next query is. Is there is any equivalent function to OnDestroy() in CXTPControlComboBox? Please.
