You aren't going to leave it this way, are you?

My problem is installing ActiveX will not work if the user doesn't have admin rights.

So can't you just assign those (rights) via AdjustTokenPrivileges()?

I looked that the list of (rights) http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/privilege_constants.asp[^] and I am having trouble with which one to turn on. I have tried SE_BACKUP_NAME and SE_LOAD_DRIVER_NAME and they dont seem to work.

I also found a class that I think helps with the setting of privileges. http://www.codeproject.com/system/NtRegistry.asp[^]. I used the function EnablePrivilege with these two setting and still no luck?

I dont know what to do about putting them on the C:\. I could put it in the "All Users\Documents" folder via CSIDL_COMMON_DOCUMENTS. Do you have any better ideas?

Checking if a window is minimized

Since I didn't want to use MFC after reading all the tutorials on here for minimizing an application to the system tray, I did some research and made it so my program has a tray icon. Now, my only problem is, how do you detect when a window's minimize button is pressed in Win32? I've scoured MSDN and asked on a few forums, but nobody seems to be willing to give a direct answer.

I got it to work another way, but this is nice to know. Thanks.

Now I have another problem. Apparantly it doesn't respond to this:

[code]case WM_TRAYMESSAGE:
{
if(lParam == WM_LBUTTONDOWN)
{
ShowWindow(hWnd, SW_SHOWDEFAULT);
}
} break;[/code]

Any ideas? Confused | :confused:

What other way is there to check if a window is minimized?

Is this a User-Defined Message (UDM)? If so, where is it sent from? Without seeing the code in context, it's going to be near impossible to offer anything useful.

I use this code:

case WM_SIZE:<br />
         {<br />
             if(wParam == SIZE_MINIMIZED)<br />
             {<br />
                 ShowWindow(hWnd, SW_HIDE);<br />
             }<br />
         } break;

Yes, it is. I was following various articles on here and tried various paramters for it. What I have it now at is this:
#define WM_TRAYMESSAGE (WM_USER + 1)

And this is the code I have for filling the structs for NOTIFYICONDATA:

    nid.cbSize = sizeof(NOTIFYICONDATA);<br />
    nid.hWnd = hWnd;<br />
    nid.uID = 0;<br />
    nid.uFlags = NIF_ICON | NIF_TIP;<br />
    nid.uCallbackMessage = WM_TRAYMESSAGE;<br />
    HICON hIco = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_MYICON));<br />
    nid.hIcon = hIco;<br />
    strncpy( nid.szTip, "App name", 64 );<br />
<br />
    ShowWindow(hWnd, nCmdShow);<br />
    Shell_NotifyIcon(NIM_ADD, &nid);<br />
<br />
    if(hIco) { DestroyIcon(hIco); }

If you need any more code, I'll post it for you.

So which of WM_TRAYMESSAGE or WM_LBUTTONDOWN are you not receiving?

Shell_NotifyIcon(NIM_ADD, &nid);

What does this return?

That's what I'm not sure of. How would I test?

Well, adding the tray icon works fine. The icon shows up and can be removed just fine.

A breakpoint. The debugger.

The debugger doesn't seem to want to work. I might have to try a different IDE and see if it will make the compiler build the file with debugging info. When trying to get the debugger to work, this warning started to come up and it is now coming up all the time when I build my project.

<quote>Project : Win32 Application

This is the code it is pointing to:

hWnd = CreateWindowEx(NULL,<br />
                      "WindowClass1",    // name of the window class<br />
                      "Our First Windowed Program",   // title of the window<br />
                      WS_OVERLAPPEDWINDOW,    // window style<br />

                      300,    // y-position of the window<br />
                      500,    // width of the window<br />

                      NULL,    // we aren't using menus, NULL<br />
                      hInstance,    // application handle<br />
                      NULL);    // used with multiple windows, NULL

The last NULL in the list is the line the compiler points to. Could this warning have an affect on the program not detecting when I click the icon?

error C2065: 'IID_ITest' : undeclared identifier

i have added respective _i.c file also then the following error is coming
fatal error C1010: unexpected end of file while looking for precompiled header directive
why..?

Thanks in before

Without more information, I'd say a .h file was missing.

doesn't that error usually mean you need to include stdafx.h???

If the compiler says "undeclared identifier" it means it can't find it. There are two possibilities:
1. A missing header file.
2. The identifies name is wrong or it's in a namespace and you haven't qualified the name with it or put in a using statement to import it.

Knock number two on the head by adding no_namespace after the #import. i.e.

#import "Voodoo.tlb" no_namespace

This tells the compiler not to use namespaces.
