Control::IsInputChar Method

Determines if a character is an input character that the control recognizes.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
[UIPermissionAttribute(SecurityAction::InheritanceDemand, Window = UIPermissionWindow::AllWindows)]
protected:
virtual bool IsInputChar(
	wchar_t charCode
)

Parameters

charCode
Type: System::Char

The character to test.

Return Value

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

Call the IsInputChar method to determine whether the character specified by the charCode parameter is an input character that the control wants. This method is called during window message preprocessing to determine whether the specified input character should be preprocessed or sent directly to the control. If IsInputChar returns true, the specified character is sent directly to the control. If IsInputChar returns false, the specified 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.
