Hi

I've looked almost everywhere for this functionality without finding it, you will need to do some vbs as far as I have found out.

If you should run into something that handles this well, please post an update to this thread, thanks.

Best regards

Ole

Hi Ole, Thanks for the advice. yes, i can confirm that currently

no existing functions can achieve that,

and looks like ipc functions with some vbs is the only way to go.

so the first step (Sorry but i am new to the ipc functions)

i wish to achieve is a simple try.vbs which prints a "Hello World" string @

Windows command prompt, and it is able to be captured and stored in a SKILL variable.

the try.vbs comes with a single statement of:  Wsh.Echo "Hello World"

and in my SKILL function: 

defun( ipc_tst ()
         cid = ipcBeginProcess( "try.vbs")
         ipcWaitForProcess(cid)
         ipcReadProcess(cid)
)

but i keep on getting an error of :    

Skill > ipc_tst
"Cannot create child process 'try.vbs '; Error code: 193\n"

it seems like the child process cannot be initiated.  how shall i go to

capture the "Hello world" which is printed by a vbs script?

Thx

 You should try the following:

   cid = ipcBeginProcess( "C:\\WINDOWS\\System32\\WScript.exe try.vbs")

- the location of the Visual basic script engine (WScript.exe) may be different on your system

- if try.wbs is not in the current directory you may need to prepend its path

Hi fxffxf, Thanks for the help. Yes, the child process is now running.

i got another problem is the output cannot be captured by the ipcReadProcess(cid),

even i am quite sure that the vbs function returns something.

an example is, a "Time" function in the try.vbs returns the system time, but it could not

be captured and ipcReadProcess returns nil every time. i am wondering whether there

is any function in vbs can pass the output to stdout so that ipcReadProcess can capture it.

Thanks again for the help, appreciate that. 

The ipc process requires the child program write to standard out (stdout) to send info back to Allegro.

Basically you should first see if you can interact with your program in a cmd.exe window.You could search google on vbs versus stdout write.
