LastDLLError Property

Returns a system error code produced by a call to a dynamic-link library (DLL). Read-only. LastDLLError always returns zero on the Macintosh.

Remarks

The LastDLLError property applies only to DLL calls made from Visual Basic code. When such a call is made, the called function usually returns a code indicating success or failure, and the LastDLLError property is filled. Check the documentation for the DLL's functions to determine the return values that indicate success or failure. Whenever the failure code is returned, the Visual Basic application should immediately check the LastDLLError property. No exception is raised when the LastDLLError property is set.
