View source for DrgVerifyType

This function verifies whether a given type is present in the list of types defined for a drag object.

==Syntax==
 DrgVerifyType(pDragitem, pType)

==Parameters==
;pDragitem (PDRAGITEM) - input: Pointer to the DRAGITEM structure whose hstrType is to be verified.
;pType (PSZ) - input: String specifying the types to search for. This string is in the format: type[,type...]

==Returns==
;rc ([[BOOL]]) - returns: Success indicator.
:: TRUE - Successful completion.
:: FALSE - Error occurred.

==Remarks==
If at least one of the types specified by pType is present in hstrType in the DRAGITEM structure, TRUE is returned.

==Errors==
Possible returns from WinGetLastError:
;PMERR_INVALID_PARAMETERS (0x1208): An application parameter value is invalid for its converted PM type. For example: a 4-byte value outside the range -32 768 to +32 767 cannot be converted to a SHORT, and a negative number cannot be converted to a ULONG or USHORT.
;PMERR_INSUFFICIENT_MEMORY (0x203E): The operation terminated through insufficient memory.

==Example Code==
This example verifies whether a given type is present in the list of types defined for a drag object.
