I'm have a heck of a time trying to get a tray icon to change during runtime. I've added a second icon to my resource file, using Borland's Image Editor, but the image doesn't appear to be in the exe? I use the LoadIcon() function to load it during runtime; see code below. void __fastcall TfrmMain::UpdateIcon(const char *ptr_chrHint, bool boolDisIcon) { NOTIFYICONDATA IconData; if (boolDisIcon) //Disabled icon desired IconData.hIcon = LoadIcon(HInstance, "DISABLEDICON"); else IconData.hIcon = LoadIcon(HInstance, "MAINICON"); IconData.cbSize = sizeof(NOTIFYICONDATA); IconData.uID = IDC_TRAY1; IconData.hWnd = Handle; IconData.uFlags = NIF_MESSAGE | NIF_TIP; IconData.uCallbackMessage = WM_TRAYNOTIFY; lstrcpy(IconData.szTip, ptr_chrHint); Shell_NotifyIcon(NIM_MODIFY,&IconData); } The .res file has been added to the project, and the MAINICON is in there, but what am I missing? Thanks, Jeff Back to top Mike Collins Guest Posted: Fri Aug 05, 2005 5:06 pm    Post subject: Re: Resource files??? Don't know if this helps, as I'm not 100% on trayicons but, 1) LoadIcon has been superseeded by LoadImage: LoadImage(HInstance, "DISABLEDICON", IMAGE_ICON, 16, 16, LR_DEFAULTSIZE); 2) Form what I remember, there's a TrayIcon vcl that comes with builder and uses an TImageList to hold the various images that you may wish to assign. 3) My experiance of including other resource files with the automatically generated (AG) resource file has thrown up many problems. I've always found that when the reource linker tries to combine my other resource with the AG resource file I get errors or the combination does not occure as predicted. Generally I always remove the AG resource file and replace it with a completely new one (including main icon, version info and other resource) created in Visual C++ (thats the only thing it's good for). 4) Have you tested handle that is returned from LoadIcon to see if it is sucessful?

I've added a second icon to my resource file, using Borland's Image Editor, but the image doesn't appear to be in the exe? Which resource file are you editing exactly? If you are editing the default resource file that every project has, then that is why your icon is missing. The IDE manages that file and recreates it on every compile, thus frequently losing any custom changes you make to it. Custom resources should always be placed in their own resource file that you then add to the project.

Thanks, that's what was happening. The IDE was constantly overwriting my resource file.
