AxHost.IsInputChar Method

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

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

[UIPermissionAttribute(SecurityAction.InheritanceDemand, Window = UIPermissionWindow.AllWindows)]
protected override bool IsInputChar(
	char 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 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.
