Return Value

true if the character should be sent directly to the control and not preprocessed; otherwise, false.


This method is called during window message preprocessing to determine whether the given input character should be preprocessed or sent directly to the control. If the IsInputChar method returns true, the specified character is sent directly to the control. However, if the method returns false, the character is preprocessed and only sent to the control if it is not consumed by the preprocessing phase. The preprocessing of a character includes checking whether the character is a mnemonic of another control.
