Can anybody supply me with a fulle working demo code project on grouping buttons of different applications on the Windows taskbar?
I’m using Delphi 6.

Thanks in advance

Eh, I think I’d need to re-read and re-research it all to be able to update this article. I haven’t done anything of this kind for a long time, mostly focused on web programming now.

typedef struct tagNMTOOLBAR {
NMHDR hdr;
//Command identifier of the button
//associated with the notification
int iItem;
TBBUTTON tbButton;
int cchText;
LPTSTR pszText;
RECT rcButton; //Version 5.80
} NMTOOLBAR, FAR* LPNMTOOLBAR;

My coworker found this while trying to prove me wrong about MS’ documentation on this subject. He succeeded in proving me wrong about the point I was trying to make, but at the same time proved the larger issue of MS documentation sucking right =P

This is the dwData structure in the TTBButtonInfo when talking about the taskbar, it says user defined because it really is…user defined. It can be any type of structure but by default it is an NMTOOLBAR for explorer.exe’s taskbar.

As a sidenote, please update this guide. It has been invalueable for me in writing an app I’m working on right now, and I’m sure it will be for anyone else.

Hey Ramkey, Nope, sorry. I don't usually program in VC++. There might be something in MSDN that you could use.

Hi White Shadow,

Nice article! Do you have any sample code in VC++ to retrieve Button Title & Setting New Button Title. I am currently customizing a Microsoft Management Console and want to change a few Menu items.

Thanks in Advance!

data[5] only contains the executable name if the button is a group.
It has been a while since I wrote this post so some specifics have faded from memory.

You could get *an icon* by finding the exe file for the process that created the window using the window handle and extracting the icon from the file. Read about how to find the exe here – http://www.cs.bgsu.edu/drhutch/otherinfo/appnamefromhwnd.html

That might not be the exact window’s icon but it’s better than nothing.

Hi. I am having a hard time getting the icon. It seems wm_geticon does not ever work, and GetClassLong(wHnd, GCL.HICONSM); or GetClassLong(wHnd, GCL.HICON); does. But I noticed in a rare case (remote desktops input capture window) does not get the icon and it crashes. I tried every method you suggested but I cant seem to get the information I need. I tried using ImageList_GetIcon but it always returns 0. I was giving it a valid handle from TB_GETIMAGELIST. I then tried to use ExtractIcon but I was unable to get the path to the executable from data[5]. I tried to read all the bytes from dwdata but the only readable text I found was part of the buttons name. I’m probably doing something wrong so I was wondering if you could help. Btw I am using c# and the readprocessmemory method of code injection.
