Hello , i have a COM Dll Which is having different functions. When I loaded the dll using Call Library function node, it is successful. But while selecting my Exposed function which is having UserDefined DataStructures it is giving Labview Run time error. But it is allowing other functions that do have the primitive data types. Can you please tell me how to overcome my problem? Here I am attaching my Com Dll please check it. There are 3 functions which use UDT's ie. IIinitializeCanCardDriver, ICAN_Write and ICAN_Read functions. Please let me correct if I am wrong path. And can you let me know what are the other problems that may cause due to UDT's access from Labview.
