public:
 static bool IsValidMaskDescriptor(System::Windows::Forms::Design::MaskDescriptor ^ maskDescriptor);
public static bool IsValidMaskDescriptor (System.Windows.Forms.Design.MaskDescriptor maskDescriptor);
public static bool IsValidMaskDescriptor (System.Windows.Forms.Design.MaskDescriptor? maskDescriptor);
static member IsValidMaskDescriptor : System.Windows.Forms.Design.MaskDescriptor -> bool
Public Shared Function IsValidMaskDescriptor (maskDescriptor As MaskDescriptor) As Boolean

Parameters

maskDescriptor
MaskDescriptor

The mask descriptor to test for validity.

Returns

Boolean

true if maskDescriptor is valid; otherwise, false.

Remarks

The IsValidMaskDescriptor method determines whether maskDescriptor is valid and can be added to the masks list.

A valid MaskDescriptor must meet the following conditions.

  • Not null.

  • Not null or an empty mask.

  • Not null or an empty name.

  • Not null or an empty sample.

  • The sample is correct based on the mask and all required edit characters have been provided. This means the mask is completed but not necessarily full.

  • The sample is valid based on the ValidatingType object, if any.
