Database disconnected problem

I built a Labwindows project and paste it to the remote desk.But the database cannot connect. Here is my code. They say that it is the problem is relating to different version of CVI. I use Labwindows 2009, but I tried again using Labwindows 8.5, I failed again.

errors while click the exe file in the remote desk:

popup the message:"警告！","数据库连接失败！ which means database disconnect in English.

I will be very grateful if anyone can help me solve the problem. Thank U very much!!!
