Thank you for your help anyway

Hi Andrew,

I suggest you to look at this thread and test Martin library to find available COM ports: it seems to me that it should be of much help in your trouble.

Thank you so much! It works! It's the second time you help me out. You are awesome!!!

You're welcome!

That's what the forums are for: something with a little more experience or (like in this case ) a better memory can help other users to use CVI better and better. I learned a lot through forum posts and continue learning.

Since that thread I posted source code that works in CVI, without the need for the DLL. See this post.

Hi Martin,

Thank you for sharing your solutions. When I tried to use this solution, http://forums.ni.com/t5/LabWindows-CVI/What-CVI-functions-do-I-need-to-use-in-order-to-check-the/m-p..., it gave me an error saying setupapi.h is not found. 

I also tried your older one, http://forums.ni.com/t5/LabWindows-CVI/Check-com-port/m-p/221306#M16380. It worked, but the problem is that I need to combine it with other codes which use __stdcall calling convention when building it(since it need to link to some dll explicitly), while your solution need to use __cdecl.

Actually, I just wanna set up the port numbers automatically before starting the test program. Is it possible to combine them in either way? 

Thank you so much.  I am looking forward to your response.
