Hi,
I have win32 Api Windows Application, my application goes on to system tray intially and keeps running. I have handled event On Left click on application in system tray in WndProc. In this we call a custom balloon Function. Below is part of code i have in WinMain which Push application to system tray
NOTIFYICONDATA structNID; //This is defined Globally Above WinMain
structNID.cbSize =
sizeof(NOTIFYICONDATA); // sizeof the struct in bytesstructNID.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 traystructNID.uFlags = NIF_ICON | NIF_MESSAGE | NIF_TIP;
//ORing of all the flagsstrcpy_s(structNID.szTip,
"Test App"); //Text of the tooltipstructNID.hIcon = hMainIcon;
// handle of the Icon to be displayed, obtained from LoadIconstructNID.uCallbackMessage = WM_USER_SHELLICON;
//put the actual icon now
Shell_NotifyIcon(NIM_ADD, &structNID);
Below is code for Balloon Function
string msg = "Test";
structNID.cbSize=
sizeof(structNID);structNID.uFlags = NIF_INFO;
structNID.uTimeout = 50;
string appname = "Testing";
strcpy_s(structNID.szInfo, msg.c_str());
strcpy_s(structNID.szInfoTitle, appname.c_str());
Shell_NotifyIcon(NIM_MODIFY, &structNID);
This works well and shows balloon tip if i compile the application using Visual Studio 2005 without installing Windows Vista SDK. In case i install Win Vista SDK and compile it using VS 2005 the balloon stops coming. Can some one help me
Balloon Tooltip Problem using Win Vista SDK

Maybe you need to initialize hWnd member and specify the uTimeout value in milliseconds when you display the balloon

Hello friends,
Ultimately after lot of hit and trail i found a solution to this issue. Let me tell you 1st that the application shows balloon perfectly well in windows Vista. It was giving problems only in other OS. When i checked sizeof(NOTIFYICONDATA); it was different if WinSDK was installed, it was 508 Bytes while it was 504 bytes in case WinSDK is not installed. This is due to reason a new member of hBallopIcon is added in shellapi.h to this structure. I dont know if this was creating problem, but what i did was replaced shellapi.h that came with winsdk with one which is there with Visual studio 2005 and things started working perfectly fine on most of OS. I still havent tested it on Windows Vista, will soon do it and let you know result on it. Still i am not able to understand it is bug in WinSDK or do i need to pass some hBalloonIcon or more parameter in case i wanna use shellapi.h which came with WinSDK
Anyone Interested please reply with there thoughts/suggestion/comments..

Hi,
About Hwnd i have intialized it,
hWnd is declared globally and in WinMain i m doing
hWnd = CreateWindow("Test",
"Test ",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
NULL,
hInstance,
NULL);
Also in Balloon function as posted above in code, i am setting uTimeout as 50, even setting it to 50000 doesnt work. And if i havent installed winSDK for Vista it works perfectly fine. Why is it so

The Perfect solution was to declare a Macro which tells the compiler the lowest version that Application must support and it worked fine.
