Since this function is only supported in Windows 2000 and later, you need to make sure that the WINVER #define value is set to 0x500 or greater before you include windows.h.

Hi folks, I'm trying to associated the desktop window with LRESULT CALLBACK WindowProcedure(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam;
this is what I did:
hWnd= GetDesktopWindow();
WNDCLASS desktopClass;
char className[200];
GetClassName(hWnd,className,200);
BOOL res=GetClassInfo(hInstance,className,&desktopClass);
desktopClass.lpfnWndProc=WindowProcedure;
RegisterClass(&desktopClass);
MessageBox(hWnd,className,"",MB_OK);
however the WindowProcedure was not called. why?
thanks!!

By calling RegisterClass you are changing that class for all subsequent calls to CreateWindow for that class.
If you want to change the wndproc for a class of a window that has already been created you will need to call ::SetClassLong and set the GCL_WNDPROC index.
Optionally if you just want to subclass one specific window you should use ::SetWindowLong and replace the wndproc for that one window with GWL_WNDPROC.
I am not sure that you will be able to do what you are trying to do unless you can get your code loaded into the same process that created the desktop window (probably explorer.exe). Because the address that you set for the wndproc will be in a different address space and will not be accessible unless it is in the same process.

you are right that I can't set GWL_WNDPROC attribute if the windowdoes not belong to the same process. This is what msdn doc says:
GWL_WNDPROC
Sets a new address for the window procedure.
Windows NT/2000/XP: You cannot change this attribute if the window does not belong to the same process as the calling thread.
so does this mean there's no way I can listen to the msg that's been send to the desktop window and respond to those msgs?
thanks a million

I would not necessarily say that, because everything that I have put my mind to, I have been able to accomplish in one way or another for Win32.
However, I was looking at Spy++, and it does not allow you to recieve the messages from the Desktop window. So if you can get the messages I think that you will have to do something that is not very mainstream. I dont have any suggestions of where to start either.

Ok heres's what I want to do ultimately: I want to be able to detect a mouse press down on the desktop window, and I've seen program such as a screencapture program able to do that, so it has to be possible, right? so is there a way of accomplishing that without listening to the msgs that are sent to the desktop window?
thanks!!

You can install a global mouse hook to listen for mouse clicks, or you can use DirectInput with a background to listen for the mouse clicks.
When you get a mouse click message use ::WindowFromPoint() to determine if the user clicked on the desktop window.

thanks, I installed a global hook and played around with it. but it doesn't work well, in particular, if I do the following, does it it put all the variables in global dll? it got lots of weird behavior from my diligently produced code(I copy and pasted below). Sometimes if I restarted my computer it seems that the hook was catching the mousedown message if i press anywhere on desktop, but sometimes it doesn't, in the best case it's crashing the system. would you provide me with some code snipet that install a mousehook and print the mouse position when the user left click the mouse?
thanks a million!
#pragma data_seg(".IdleTrac") // you must define as SHARED in .def
HHOOK mouseHook,keyboardHook;
HINSTANCE g_hinstance;
#pragma data_seg()
#pragma comment(linker, "/section:.IdleTrac,rws")
LRESULT CALLBACK KeyboardProc(int nCode, WPARAM wParam, LPARAM lparam){
switch(wParam){
case 27:
UnhookWindowsHookEx(mouseHook);
UnhookWindowsHookEx(keyboardHook);
errstream.close();
PostQuitMessage(0);
}
return 0;
}
LRESULT CALLBACK MouseProc(int nCode, WPARAM wParam, LPARAM lparam){
// MessageBox(hWnd,"in mouse proc ","",MB_OK);
MOUSEHOOKSTRUCT* mousehook=(MOUSEHOOKSTRUCT*)lparam;
POINT p=mousehook->pt;
switch(wParam){
case WM_LBUTTONDOWN:
MessageBox(hWnd,"leftt button down","",MB_OK);
// errstream<<"mouse position is "<

Hello
I want to build tools in MS office (eg. Acrobat Icon that appear in MS Office after install Acrobat Writer) but I don't know how and I should use which language(my teacher advise me to use ActiveX or VBA or VC++),please help me ...very thanks

I don't know if this will be much help but you might look at using COM. I had to incorporate MS Word into an application and put a special button on the Word toolbar. It isn't easy if you are a beginner but it is possible. There are several good examples out there, Amit Dey has one that is really good. If you haven't already looked around, you might start by looking here:

If all depends on how much you know and how much you want to know....

Hi There,
I have a class derrived from a CComboBox class, and I really need to recieve notification - SelEndOK for example, but from what I can make out messages are transmitted to the parent window, and a derrived class doesn't recieve the any kind of notification. Is there any way to recieve get these messages?
Any help would be much appreciated...
With time we live, with money we spend!

Use the ON_CONTROL_REFLECT macro in your message map to handle the notifications in the CComboBox-derived class.

Heyo, (english version ... when u can call it  is attached as reply)
Ich versuche im Moment in einer EXE-Datei einen Import zu verändern, dass klappt ganz gut und wunderbar, wenn diese Funktion aus der EXE-Datei heraus aufgerufen wird.
Sobald ich dies aber bei einer anderen EXE-Datei machen möchte, bei der ich in den Prozess eingeschleust werde - über ein WH_CBT - funktioniert dies jedoch nicht, da die DLLs zu diesem Zeitpunkt noch nicht initialisiert wurden.
Da bereits in der win_main der veränderte Import benutzt werden soll kann ich auf keine anderen Hooks zurückgreifen.
Weis jemand wie ich An die Initialisierte Importtable komme, bevor diese benutzt wird ?
Vielen Dank schonmal
Also, ich setze einen CBT Hook:
(innerhalb der DLL die in den Zielprocess reinmuss)
<br />
LRESULT CALLBACK CBTProc(int nCode,WPARAM wParam,LPARAM lParam) {<br />
return CallNextHookEx(CBThook,nCode,wParam,lParam) ;<br />
} ;<br />
<br />
void WINAPI InstallNCT(void) {<br />
GWMhook = SetWindowsHookEx(WH_CBT,&CBTProc,GetModuleHandle("MYDLL.dll"),NULL );<br />
} ;<br />
Dieser Code wird mit der ProzessID des Launchers ausgeführt. Sobald ein neuer Prozess erstellt/aktiviert ist wird der folgende Code durchgeführt:
<br />
BOOL APIENTRY DllMain( HANDLE hModule, <br />
DWORD ul_reason_for_call, <br />
LPVOID lpReserved<br />
)<br />
{<br />
switch (ul_reason_for_call)<br />
{<br />
case DLL_PROCESS_ATTACH:<br />
if (isZielProzess()) {<br />
HMODULE thismod = GetModuleHandle("MYDLL.dll") ;<br />
LPVOID addr = GetProcAddress(thismod,"MyOverrideFunction") ;<br />
ChangeImport_("D3DDrv.dll","DDRAW.dll","FunctionName",addr) ;<br />
} ;<br />
return TRUE ;<br />
case DLL_THREAD_ATTACH:<br />
case DLL_THREAD_DETACH:<br />
case DLL_PROCESS_DETACH:<br />
break;<br />
}<br />
return TRUE;<br />
} ;<br />
Wobei ChangeImport_(ModulName,ImportModulName,ImportFunctionName,Addresse) ;
in der MudulName.dll den Import aus der ImportModulName.Dll mit dem Namen ImportFunctionName mit der Addresse überschreibt.
Nun funzt das nicht, da die D3DDrv nich initialisiert ist... aber ich brauchs funzent

In English:
I want to modify import locations. Therefor i CBT hook 'em and change them at the DLL_PROCESS_ATTACH.
But this doesnt work and because the dlls are not yet initialized when i want to modify.
(see code above)
How can i change the imports form other prozesses ?
Thx in advance.

This might do it, but I haven't tried it.
<code>LONG RegQueryInfoKey(
HKEY hKey,
LPTSTR lpClass,
LPDWORD lpcClass,
LPDWORD lpReserved,
LPDWORD lpcSubKeys,
LPDWORD lpcMaxSubKeyLen,
LPDWORD lpcMaxClassLen,
LPDWORD lpcValues,
LPDWORD lpcMaxValueNameLen,
LPDWORD lpcMaxValueLen,
LPDWORD lpcbSecurityDescriptor,
PFILETIME lpftLastWriteTime
);</code>

I want to test one of M$ examples,"Starting an Interactive Client Process".At the begining of it,there is these lines:
#define DESKTOP_ALL (DESKTOP_READOBJECTS | DESKTOP_CREATEWINDOW | \ DESKTOP_CREATEMENU | DESKTOP_HOOKCONTROL | \ DESKTOP_JOURNALRECORD | DESKTOP_JOURNALPLAYBACK | \ DESKTOP_ENUMERATE | DESKTOP_WRITEOBJECTS | \ DESKTOP_SWITCHDESKTOP | STANDARD_RIGHTS_REQUIRED)
#define WINSTA_ALL (WINSTA_ENUMDESKTOPS | WINSTA_READATTRIBUTES | \WINSTA_ACCESSCLIPBOARD | WINSTA_CREATEDESKTOP | \ WINSTA_WRITEATTRIBUTES | WINSTA_ACCESSGLOBALATOMS | \ WINSTA_EXITWINDOWS | WINSTA_ENUMERATE | \ WINSTA_READSCREEN | \ STANDARD_RIGHTS_REQUIRED)
Whenever it use DESKTOP_ALL and WINSTA_ALL,I got "C2017:illiegal escape sequence".I have to delete \ there to get rid of this error,Could anybody please tell me about this charachter here?

It looks like the original code was
#define DESKTOP_ALL (DESKTOP_READOBJECTS | DESKTOP_CREATEWINDOW | \
DESKTOP_CREATEMENU | DESKTOP_HOOKCONTROL | \
DESKTOP_JOURNALRECORD | DESKTOP_JOURNALPLAYBACK | \
DESKTOP_ENUMERATE | DESKTOP_WRITEOBJECTS | \
DESKTOP_SWITCHDESKTOP | STANDARD_RIGHTS_REQUIRED) and got reformatted. Putting a backslash at the end of a line makes the preprocessor join that line and the next into one big line. You usually only see this with huge macros, like your examples.
