WaitForSingleObject and setup.exe ????

[ipazzo]

Hi All,
I'm want to execute a setup program from my FOX application. I use the
CreateProcess API function and WaitForSingleObject WIN API function to
accomplish this. When I execute notepad.exe, the WaitForSingleObject
function waits untill I close the notepad. But when I'm executing the
required exe(the command line is "E:\INSTALL\WIN32\setup.exe&quot
the WaitForSingleObject function is not waiting for the setup to finish or
exit.
Please helpme with this.

Thanks

Hi

WaitForSingleObject (WFSO) doesn't have to wait for the process to finish. Just look for the API name we can tell that it waits for a single (whatever) object/signaled

I've never get the situation like you, but maybe Setup.exe is signaling something (other than exit) to the calling process. So you need to trap that signaled.

Use GetExitCodeProcess for that, and check if the exitcode is equal to STILL_ACTIVE, loop to WFSO again

Hope it helps

Ipazzo,

I'm not sure if this will help, but, as an alternative to using those API functions, the Windows Scripting Host has a Run method which can optionally wait until the target application has closed.

Here is the code:

oWsh = CREATEOBJECT("wscript.shell&quot
oWsh.Run("Notepad",1,.T.)

The second parameter to Run is the window state. The third param is .T. if you want the caller to wait until the called program has closed.
