Win32 api CreateProcess() with LabVIEW

[Meng-Shiang.Lin]

I'm trying to use win32 API CreateProcessA for opening a console application.

The function always return 0, but it never open the cmd.exe. I already checked function

syntax on MSDN.

Please kindly advise, any comments would be appreciated.

LabVIEW 8.5, XP SP2

Hi Adam,

is there a reason to not use the SystemExec.vi?

Hi Mike,

I had a console application from customer, this application will alarm and warn users to do something,

so I need to know the HANDLE of application to record warnings and take corresponding actions.

Hi Adam1122,

the return value 0 means an error occurs. If you only need the handle of the console applicaiton, then you can try it with the FindWindow function from user32.dll.
