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)

Syntax

Visual Basic

<UIPermissionAttribute(SecurityAction.InheritanceDemand, Window := UIPermissionWindow.AllWindows)> _
Protected Overrides Function IsInputChar ( _
    charCode As Char _
) As Boolean

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

Visual C++

[UIPermissionAttribute(SecurityAction::InheritanceDemand, Window = UIPermissionWindow::AllWindows)]
protected:
virtual bool IsInputChar(
    wchar_t charCode
) override

[<UIPermissionAttribute(SecurityAction.InheritanceDemand, Window = UIPermissionWindow.AllWindows)>]
abstract IsInputChar : 
        charCode:char -> bool 
[<UIPermissionAttribute(SecurityAction.InheritanceDemand, Window = UIPermissionWindow.AllWindows)>]
override IsInputChar : 
        charCode:char -> bool

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.

Remarks

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.
