Execute command line is very slow when runtime engine

[LiaoPH]

Hi,

I would like to execute a  command line by system exec. vi, and when I execute in development environment that cost about 80 ms. But when I build EXE and execute in runtime environment, it cost 36 seconds.

Did I do something wrong?

Here is my source code

Does the command succeed after 36 sec or fail? Maybe you could output the output and error info, and maybe also not minimise the window, just to see what happens.

You could also try disabling UAC temporarily to see if that alleviates the problem. And like Thols mentioned, check the STD out and ERR out for messages.

Thanks everyone for gave advice.

I had try to enable/disable UAC and still not work. Finally that is  IT of our company locked something like UAC...
