For those still interested:

Code:

Process, Exist
pid := ErrorLevel

MsgBox, % "pid = " pid "`n`nname = " GetModuleFileNameEx( pid )
return

GetModuleFileNameEx( p_pid )
{
   if A_OSVersion in WIN_95,WIN_98,WIN_ME 
   {
      MsgBox, This Windows version (%A_OSVersion%) is not supported.
      return 
   }

   /*
      #define PROCESS_VM_READ           (0x0010)
      #define PROCESS_QUERY_INFORMATION (0x0400)
   */
   h_process := DllCall( "OpenProcess", "uint", 0x10|0x400, "int", false, "uint", p_pid )
   if ( ErrorLevel or h_process = 0 )
   {
      MsgBox, [OpenProcess] failed
      return
   }
   
   name_size = 255
   VarSetCapacity( name, name_size )
   
   result := DllCall( "psapi.dll\GetModuleFileNameExA", "uint", h_process, "uint", 0, "str", name, "uint", name_size )
   if ( ErrorLevel or result = 0 )
      MsgBox, [GetModuleFileNameExA] failed
   
   DllCall( "CloseHandle", "uint", h_process ) ; Corrected by Moderator! 2010-03-16
   
   return, name
}

You're on a roll!

Closely related, but probably much harder to do, if not impossible at the moment with AHK - can you think of a way to get the icon associated with a process (i.e. the one that would be displayed on the taskbar). This would save all the "MUICache" trouble altogether.

I searched through the forum and didn't find any scripts that could do this.

Well, now you are just greedy (not LOL, but amusement)...

putting together the pieces of the puzzle, you realize:

Wow!

See how easy it is when I guide you through the process? :lol:

Maybe you should post that in the "Scripts & Functions" forum as it's a really straightforward demonstration of getting which windows are on the taskbar, process paths and their window icons.

Where it does have a failing is with the icons for "windows components" such as Disk Defragmenter (Windows XP), which displays the mmc.exe icon instead of the window's icon which is extracted from shell32.dll.

Another case is with the AutoHotkey help file - when launched on its own from the start menu, it has the correct icon (and is running as hh.exe), but launched from inside PSPad, the script picks up the PSPad.exe icon as the help file seems to run as part of that process and not a seperate one.

Sure. It's teamwork.

Not quite. I was a bit overzealous. While the icons retrieved by the script happened to be correct, there is a possibility that the actual icons displayed will differ.

I'll review window classes later and post the correction.

That should be right, but unfortunately, that message may fail to retrieve an icon.

I've been playing around with the code today and getting it to display a list of icons and their window titles in a gui for all running programs (like an alt-tab replacement). (I did have a look into getting the icons into a listview, but it seems way more complicated than the static control picture replacement method!)

I managed to find one type of window that doesn't get listed. Some of the settings windows found in control panel, in Windows XP, (e.g. "Date and Time", "Sounds and Audio Devices" and "Taskbar and Start Menu") do display in the normal alt-tab list but not on the taskbar.

There are differences between taskbar and task switcher characteristics.

I could not find any documentation to describe the task switcher (via Alt+Tab). From what I can infer, windows of the dialog class are an exception for the task switcher; but, you will have to fully characterize the circumstances of their appearance in that function.

As for the Control Panel applets, let's take the "Date and Time" applet as an example. I have only been able to determine that the associated icon is located in its file (timedate.cpl). If that is true, then it will be necessary to establish a window to file mapping. One method is a static mapping of window title to file:

title = Date and Time Properties
file = timedate.cpl

Another method is to determine the applet launched with RunDll32 by parsing the command line. This will require remote process access.

However, the goal was to replicate the taskbar functionality.

Check the following:

1. LVM_GETIMAGELIST = 0x1000+2
2. ImageList_Add

Code:

LVSIL_NORMAL = 0
LVSIL_SMALL = 1
LVSIL_STATE = 2

For finding the control panel windows (and those of at least one other program) that appear on the Alt-Tab list, I found that they all have the ahk_class #32770. I've only assigned a generic icon so far since it's not really a big issue for me.

And for the insertion of the icons into the icon list, someone missed a good opportunity to tell me to RTFM since I found it in the large ListView example in the manual :lol:

I'm working on an Alt-Tab replacement with icons and window titles in a listview, which I'll post the code for as soon as I've tidied it up a bit, since I saw someone else asked about that in another Alt-Tab replacement thread.

I assumed you had referred to the manual first. And... I would never say something like that, given that I believe you have made an honest attempt to solve the problem yourself.

You're right. This time I didn't read the manual.

Chris's examples are often above and beyond expectation.

Can these commands (get process name,path,folder) get added in AHK soon PLEASE ?

i "guess" it will be easy since the "method" is known to some extent.

I posted details in another thread which uses a modified version of your function, shimanov, but the same fix needs to be applied here - the call to DllCall() on the second last line is missing the second type parameter of "UInt".
