        Ya u r correct. I used breakpoint also. Still i couldnt get the output window. I put breakpoint in OnInitDialog and PreTranslateMessage. once i press debug button, it directly goes to pretanslatemessage function and then goes to the end of the program. since i dun input any char if( WM_KEYDOWN == pMsg->message ) becomes false. so it goes to the end of the pretanslate function. in this case i can see the minimized window in the taskbar. but i couldnt maximize it. eventually i couldnt see the output window. :( Regards, Ram

                      Let me explain my objective briefly. I need to desing combobox in such a way tat user can only enter the character "D", "I" and "0-9", in the combobox. If a user enters other character than the above specified, it should not be displayed in the Combobox. and the maximum no of character user can enter is only 5. this is my objective. with the current code, i can only enter one character. if i press the other character, the new one replaces the old character in the combobox. lets say i wannu enter "HELLO" if i press "H" message box shows H. then if i enter I, this I replace the H in the combobox. :(:^) again thanx a lot for ur spending ur valuable time for me.
