Check for NULLs Returned from DLL Calls

Check for NULLs Returned from DLL Calls

After a call to a DLL, the return value often contains a null.One way to eliminate the null is to look for Chr$(0), as in theexample:

 Dim CheckForNull As IntegerCheckForNull = Instr(YourString, _        Chr$(0))If CheckForNull > 0 then YourString = _        Left$(YourString, CheckForNull - 1)
