documenting seans functions would be like documenting ahk's source so that a novice could understand it

Apparently you have never actually looked at the source of autohotkey... I'll give you a random snippett here:

do we really think that explaination would help any one maybe Chris wants these examples alone on the first page

Chris wants some examples or documentation because it is going into the Script Showcase . The Script Showcase includes the very best scripts (as seen in Chris' eyes). Is it really too much for him to ask for some sort of consistency in the user scripts he is including with the installer? I think not.

PS: Please stop using large red type to try to get your point across. It is annoying. Also please attempt to make complete and coherent sentences.

That is the exact reason that you should not even be posting your ramblings.

Oh and by the way...the post you replied to is over a year old.

Streaming ability was added to StdCreateProcess(). If specify the parameter bStream to True it'll create a console window and display line-by-line the result, in addition to returning the result as a whole.

This function is so unbelievably helpful to me, I wanted to thank you updating it so it has ability to stream. The question I have is how to specify my own callback function rather than using the console window?

I currently have my own modded version of function that does this, but would prefer to not use a non standard version of your function for my stdlib.

Code:

  Loop
    If   DllCall("ReadFile", "Uint", hStdOutRd, "Uint", &sTemp, "Uint", nTemp, "UintP", nSize:=0, "Uint", 0)&&nSize
    {
      NumPut(0,sTemp,nSize,"Uchar"), VarSetCapacity(sTemp,-1), sOutput.=sTemp
      If   bStream&&hCon+1
        Loop
           If   RegExMatch(sOutput, "[^\n]*\n", sTrim, nTrim)
            %bStream%(sTemp), nSize ? nTrim+=nSize : ""
           Else   Break
     }

Please let me know if there is something simple I am overlooking with how I could be utilizing the console window method that you have provided. Thanks!

As it's easy to incorporate the custom callback function into StdoutToVar_CreateProcess() I implemented it. You can pass the custom function name to bStream instead of True. For example,

Code:

; Custom Function Name must not consist solely of numbers!
MsgBox % sOutput := StdoutToVar_CreateProcess("ping.exe www.autohotkey.com", "Stream")
; Custom Function Name is "Stream" in this example!

Stream(sString)
{
;   Custom Routine here! For example,
   OutputDebug %sString%
}

Wow. I didn't realize that you implemented like that from reading your description of new functionality. :oops:

That is how the modification I made above works too. I reverted to using the StdoutToVar.ahk posted in initial post (I can only assume that it is the most recent version)-- but still doesn't display OutputDebug, and if I run script from explorer it keeps displaying results in console window (my callback function for streaming isn't getting called at all :?:

)

Code:

MsgBox % sOutput := StdoutToVar_CreateProcess("ping.exe www.autohotkey.com", "Stream")
; Custom Function Name is "Stream" in this example!

Stream(sString)
{
;   Custom Routine here! For example,
   tooltip, received: %sString%
}

I also tried putting a msgbox in my function-- but the only msgbox that shows is for the returned sOutput.

Anyway, thanks for taking time to give example utilizing a callback routine.

Sorry, I wasn't clear enough. I meant implemented after your request. Please download again.

Is there any way to implement CTRL & C function like it works in cmd?

Someting like:

Code:

StdoutToVar_CreateProcess(sCmd, bStream = "", sDir = "", sInput = "", sHotkey="")

No, without defeating the very purpose of this script. The closest thing you can do may be TerminateProcess or alike.

Excellent script!

However it seems to crash without notice when the command is not correct, like:
MsgBox % x:= StdoutToVar_CreateProcess("plop")
MsgBox "ok !"

Also, StdoutToVar_CreateProcess("dir") doesn't work, you have to write
StdoutToVar_CreateProcess("cmd /K dir")

Is that normal behavior?

It's not a crash, it'll just execute ExitApp if failed to create a process as it's pointless to keep running then.

Yes, it's a normal behavior. dir is not a stand-alone application, it's an internal command of the command prompt, cmd.exe.

Ah ok I see. Well, I d'ont like my app to exit when one function call fails

Fortunatly, this can easily be changed

Ok, I thought it would be something like that. Thanks!
