Does the PreTranslateMessage of you dialog get called, if you click the
mouse somewhere in your dialog (other than on the combobox)?

If it doesn't then you have a bug somewhere.

I don't know about a Windows CE program, but if you set a breakpoint at the
beginning of PreTranslateMessage and try to debug you will get stuck in an
infinite loop of focus problems, and you will never be able to run the
program, the breakpoint will constantly hit!

Hello,

I work on a CDialog based application running on Windows CE, on a selling
terminal with a specific keyboard.

The CDialog has got a CComboBox control.
I use the PreTranslateMessage() function to manage the specific keys are
receive from the terminal keyboard.

Sometimes, in my interface, there is nothing but the empty CDialog with
the CComboBox with its first item selected. I set the focus to the
CComboBox with its SetFocus() method.

I set a breakpoint at the beginning of the PreTranslateMessage() function
of the CDialog, and then I hit some keys of the terminal keyboard, but I
find that neither the PreTranslateMessage() on the CDialog nor the
PreTranslateMessage() of the CComboBox are being called.

But if I do a selection in the CComboBox, then everything works fine and
the PreTranslateMessage() of my CDialog is being called.

As I need to manage the keyboards items at any time, I'd like to
understand why the CDialog doesn't get the key I hit before doing any
selection in the CComBoBox ...

Thank you !
