Tasklist - BDS107 - 08-08-2024

Can you request a list in QB64 like the DOS command TASKLIST?
You can of course use a SHELL and save the result temporarily on disk. But that is too slow if you want to update constantly. So, I don't want this.


RE: Tasklist - SpriggsySpriggs - 08-08-2024

You can use pipecom to accomplish this. I don't know where my latest code for it is. But it would work for what you're asking.


RE: Tasklist - SMcNeill - 08-08-2024

Shell with a redirect to clipboard might work as well, and then just read _ClipBoard$.

@SpriggsySpriggs

I think the pipecom version I downloaded was the one you updated in Aug of 2021 at: https://qb64forum.alephc.xyz/index.php?topic=3641.msg134943#msg134943

Could it be that you are looking for this article?

    If InStr("1234567890.", Mid$(ver, f, 1)) <> 0 Then k$ = k$ + Mid$(ver, f, 1)
Next f
If InStr(k$, "6.1.76") > 0 Then
    winver = 7
ElseIf InStr(k$, "6.2.") > 0 Or InStr(k$, "6.3.") > 0 Then
    winver = 8
ElseIf InStr(k$, "10.") > 0 Then
    winver = 10
End If
If winver = 10 Then
    For f = InStr(_Dir$(""), "User") To Len(_Dir$(""))
        If Mid$(_Dir$(""), f, 1) = "\" Then Exit For
    Next f
    utente$ = Mid$(_Dir$(""), f + 1, InStr(Mid$(_Dir$(""), f + 1), "\") - 1)

That seems to be more updated than my saved copy. + 1 for the find!

You can of course use a SHELL and save the result temporarily on disk. But that is too slow if you want to update constantly. So, I don't want this.
There's nothing built-in for this so you'll have to use OS-specific APIs for it.

On Windows, you can use `EnumProcesses` and then `OpenProcess` to get the list of all Process IDs and information about each. You can call these and the other associated APIs via `Declare Library`.

On Linux /proc is the actual API, so you should be able to do it all from QB64 code (no Declare Library necessary). Use `_FILES$` to iterate the contents of `/proc` to get all the process IDs (each process ID is a folder name). Then use `OPEN` to read the various files in each process directory to get information on each process. The docs for what files are there and what they contain is here.

On Mac OS I'm not totally sure. Google suggests there is a `libproc` library you can use, which you would then call via `Declare Library`. It seems more limited in terms of what you can read compared to Windows and Linux though.

Can you give more info on those Windows "EnumProcesses" and "OpenProcess" calls? How to call them from QB64?

There is no "ANY" type identifier in QB64.

Look at the documentation for the functions and see what the return is. my guess would be if it's numeric use AS _UNSIGNED LONG or AS DOUBLE.

Update:

Here is one of them: https://learn.microsoft.com/en-us/windows/win32/api/tlhelp32/nf-tlhelp32-process32first

but it says it needs a return of LPPROCESSENTRY32 which has its structure defined in a link on the page.
