Type: System.Char

The character to test.

Return Value

Type: System.Boolean

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

The IsInputChar method is called during window message preprocessing to determine whether the given input character should be preprocessed or sent directly to the ActiveX control. The preprocessing of a character includes checking whether the character is a mnemonic of another control.

As implemented in the AxHost class, the IsInputChar method always returns true, so the specified character is sent directly to the ActiveX control.
