IsInputChar Method (EditBase)


The character to test.
This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

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

Syntax
'Declaration
 
Protected Overrides Function IsInputChar( _
   ByVal charCode As Char _
) As Boolean
'Usage
 
Dim instance As EditBase
Dim charCode As Char
Dim value As Boolean
 
value = instance.IsInputChar(charCode)
protected override bool IsInputChar( 
   char charCode
)

Parameters

charCode
The character to test.

Return Value

true if the character should be sent directly to the control and not preprocessed; otherwise, false.
Remarks
Call the IsInputChar method to determine whether the character specified by the charCode parameter is an input character that the control requires. 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.
