Yes, I see it, but it's not working when I implement it into my code.

That's not very specific. What does the compiler say? Does it compile at all?

Well, I'm not using your class because it's more than I need. I just wrote my own few lines of code to create the icon and display it based off of MSDN and some of your code. After that, I don't see anywhere where it detects if the window was minimized. I see where it checks if the icon was clicked, ect. What I tried was what I thought was the code to detect the minimized window, but I was wrong.

Edit: Got it. For those that care, put this in your message loop:

case WM_SYSCOMMAND:        {            if(wParam == SC_MINIMIZE)            {                ShowWindow(hWnd, SW_HIDE);            } break;

But, apparantly the window doesn't stay hidden. So, does anyone know why?

You need to respond to the WM_SIZE message. Check it out on MSDN.

For quick reference, try this:


if(uMsg == WM_SIZE)
{
switch(wParam)
{
case SIZE_MAXIMIZED:
break;
case SIZE_MINIMIZED:
break;
case SIZE_RESTORED:
break;
}
}

Great! That fixed that problem, but I have another. I don't understand why it's not working. I have the window minimizing to the tray icon, but when I click on it, the window won't maximize. This is the error I'm getting. If somebody is willing to take a look at my error and my code to see if you can see why it won't maximize, it would be greatly appreciated (you don't need to do it for me, just a few pointers would do). If not, that's fine too.

And this is my basic code. It's not neat because I'm trying to just get this to work.

The error points to the last NULL in CreateWindowEx.

Thanks in advance to anyone who is willing to help.

Edit: I got the warning fixed. Right now, I'm just trying to figure out why my window won't maximize. I have the code to remove the icon from the tray there for testing purposes.

Edit 2: It seems my case WM_TRAYMESSAGE: statement isn't working.

Edit 3: Solved. Just forgot to add in NIF_MESSAGE to my nid.uFlags variable. Such a stupid mistake.
