Tests whether the specified character could be set successfully at the specified position.

public:
 bool VerifyChar(char input, int position, [Runtime::InteropServices::Out] System::ComponentModel::MaskedTextResultHint % hint);
public bool VerifyChar (char input, int position, out System.ComponentModel.MaskedTextResultHint hint);
member this.VerifyChar : char * int * MaskedTextResultHint -> bool
Public Function VerifyChar (input As Char, position As Integer, ByRef hint As MaskedTextResultHint) As Boolean

Parameters

input
Char

The Char value to test.

position
Int32

The position in the mask to test the input character against.

hint
MaskedTextResultHint

A MaskedTextResultHint that succinctly describes the result of the operation. An output parameter.

Returns

Boolean

true if the specified character is valid for the specified position; otherwise, false.

Remarks

The VerifyChar method tests whether a single character value represents valid input at the specified position in the formatted string. This method will return false for the following reasons:

  • The pos parameter is less than zero or greater than the Length of the Mask.

  • The character input is not a valid input character, as determined by the IsValidInputChar method.

  • The input is not compatible with the mask element at the specified position, pos.

The last condition may depend on the current value of the AllowPromptAsInput, AsciiOnly, PasswordChar, PromptChar and SkipLiterals properties.

To test an entire input string against the mask, use one of the VerifyString methods instead.
