Create own class id for ahk gui?

[Scr1pter]

Hi,

I found this 12 year old thread were someone had the same question:
https://autohotkey.com/board/topic/1091 ... ahk-class/

When I compile a script (e.g. one which creates an AHK gui), the class id is always:
ahk_class AutoHotkeyGUI

Is there a newer way to change the class id rather than using any hex tools?
I create guis for different applications.
If all guis have the same class id, there might be some problems.
because I often work with #if WinActive("ahk_class ...")

Try this code, it is for AHKv2 because AHKv1 is MUCH slower. Create a copy of AutoHotkey.exe and select it in the dialog box.

Code: Select all

ahkexe := FileSelect()
if (!ErrorLevel)
    MsgBox SetAHKClassName(ahkexe, InputBox(,,,"FlipeadorGUI"))
ExitApp

SetAHKClassName(File, Name)
{
    local f := FileOpen(File, "rw-wd", "UTF-16-RAW")
    if (!f)
        return FALSE

    local Buffer := ""
    VarSetCapacity(Buffer, 28)
    while (!f.AtEOF)
    {
        f.RawRead(&Buffer, 26)
        if (StrGet(&Buffer, 13, "UTF-16") == "AutoHotkeyGUI")
        {
            f.pos := f.pos - 2*13, f.Write(Name)
            loop 13 - StrLen(Name)
                f.WriteUShort(0)
            return TRUE
        }
        f.Seek(A_Index+1)
    }

    return FALSE
}

Anyway, this is a VERY bad idea. You should look for a smarter alternative to ahk_class.

Edit: You can try this for v1.

Code: Select all

FileSelectFile ahkexe
if (!ErrorLevel)
    MsgBox % SetAHKClassName(ahkexe, "FlipeadorGUI")
ExitApp

SetAHKClassName(File, Name)
{
    local f := FileOpen(File, "rw-wd", "UTF-16-RAW")
    if (!f)
        return FALSE

    local Buffer := ""
    VarSetCapacity(Buffer, 28)
    while (!f.AtEOF)
    {
        f.RawRead(Buffer, 26)
        if (StrGet(&Buffer, 13, "UTF-16") == "AutoHotkeyGUI")
        {
            f.pos := f.pos - 2*13, f.Write(Name)
            loop % 13 - StrLen(Name)
                f.WriteUShort(0)
            return TRUE
        }
        f.Seek(A_Index+1)
    }

    return FALSE
}

Interesting, how can I do this manually? when I try to open the exe in txt I do not find AutoHotkeyGUI

Open it in a hexadecimal editor like HxD.

Edit: I tried doing it in a running script with GetAddressOfData (v2) but it did not work

I tried HxD, I select my exe, I do a search for the word AutoHotkeyGUI and it finds nothing, but your script works. I tried with a exe that did not have the changed name yet.

- Here's a script I wrote to change 'AutoHotkeyGUI' to something else, live, while the exe is open, rather than editing the exe file.
test whether another script's hotkeys are still working (trigger hotkeys in another script) - AutoHotkey Community

- But I agree, it ought to be possible to choose a custom class name for GUIs, and I mentioned it in my Wish List 2.0.

Hi, thanks for the many replies!
Very interesting indeed.

A question:
Let's say I create a bigger script which contains single scripts (for different applications for example).
If I have several Guis and compile the big script to an Exe, will a hex editor show me several AutoHotKeyGui class ids?

If yes, I assume that the first found will be the first gui, the second the second gui etc.
So I guess I could simply rename those IDs even though they are in 1 big script?
