Its been a while but I loaded one of my old programs up and will attempt to paste to you what I have for the placing of an icon in the system tray and responding to the messages when a user clicks on that icon:

This goes in your WinMain

(Toggle Plain Text)

//load the icon from a resource
hMainIcon = LoadIcon(hinstance,(LPCTSTR)MAKEINTRESOURCE(IDI_ICON1)); 


structNID.cbSize = sizeof(NOTIFYICONDATA); // sizeof the struct in bytes 
structNID.hWnd = (HWND)hwnd; //handle of the window which will process
this app. messages 
structNID.uID = IDI_ICON1; //ID of the icon that willl appear in the system tray 
structNID.uFlags = NIF_ICON | NIF_MESSAGE | NIF_TIP; //ORing of all the flags 
strcpy(structNID.szTip,"Your Text"); //Text of the tooltip 
structNID.hIcon = hMainIcon; // handle of the Icon to be displayed, obtained from LoadIcon 
structNID.uCallbackMessage = WM_USER_SHELLICON; // user defined message that will be sent as the notification message to the Window Procedure 

	//put the actual icon now
	if(NOTRAY==false)
	{
		Shell_NotifyIcon(NIM_ADD, &structNID); 
	}

And for WinProc to process the messages when a user clicks on the icon in the system tray:

(Toggle Plain Text)

case WM_USER_SHELLICON://case they our over our icon in the system tray
{
 	switch(LOWORD(lParam)) 
	{ 
		//MessageBox(NULL,"IM OVER IT",NULL,NULL);
		case WM_LBUTTONDBLCLK:
	        {
		//open application or do something based on the user double clicking on the icon
		return TRUE; 
		}break;

                case WM_RBUTTONDOWN:	//they right click over our menu
		{
                //get mouse cursor position x and y as lParam has the message itself 
			GetCursorPos(&lpClickPoint);
								
		//place the window/menu there if needed 
								
		//For when the user puts their mouse over our icon in the tray
			hPopMenu = CreatePopupMenu();					InsertMenu(hPopMenu,0xFFFFFFFF,MF_BYPOSITION|MF_STRING,ID_OPEN,"O&pen");
								InsertMenu(hPopMenu,0xFFFFFFFF,MF_BYPOSITION|MF_STRING,ID_ABOUT,"&About");
								InsertMenu(hPopMenu,0xFFFFFFFF,MF_BYPOSITION|MF_STRING,ID_WEBSITE,"&Visit Our Website");
									InsertMenu(hPopMenu,0xFFFFFFFF,MF_BYPOSITION|MF_STRING,ID_OPTIONS,"Options");
								InsertMenu(hPopMenu,0xFFFFFFFF,MF_BYPOSITION|MF_STRING,ID_CLOSE,"&Close");
							
								
	//workaround for microsoft bug, to hide menu w/o selecting
			SetForegroundWindow(hwnd);
								TrackPopupMenu(hPopMenu,TPM_LEFTALIGN|TPM_LEFTBUTTON|TPM_BOTTOMALIGN,lpClickPoint.x, lpClickPoint.y,0,hwnd,NULL);
								SendMessage(hwnd,WM_NULL,0,0);						
				return TRUE; 
		}break;
							
					
	} break;
				
}break;

Then to see if the user clicked on one of the menu items like "open" close" etc...
In case WM_COMMAND:

(Toggle Plain Text)

if(ID_CLOSE == LOWORD(wParam))
	{
	Shell_NotifyIcon(NIM_DELETE,&structNID); //delete our icon
	DestroyWindow(hwnd);					//kill our window
	PostQuitMessage(0);
        }
///you get the idea......

Its been a while, but I think that should be enough to get it so that you can put an icon in the system tray, as long as the icon is in a resource file.

Sorry about the code, I tried for 5 minutes to get it to align right, I do not know how to do it yet at this site. If you have any questons just pm me, but thats the code I have from an old app I have that puts an icon in the system tray.
