function LoadSVRDLL: string; var sFile: string; begin try sFile := 'MYLIB.DLL'; SVRDLLHandle := LoadLibrary(PChar(sFile)); if SVRDLLHandle <> 1 then raise Exception.Create('Error ...'); @Uno := GetProcAddress(SVRDLLHandle,'Uno'); @Dos := GetProcAddress(SVRDLLHandle,'Dos'); result := 'OK'; Update: I have added details for ATTACH and DETACH.

In addition, if it is not "GPIB" you free a library that was never loaded.

This shouldn't slow your code down, but just give the system time to process some of the other methods that might be executing on the DLL.In CVI there is a similar
