Is there any way in C++/MFC that we can export a registry key and all its subkeys/values and save the contents to a file, like we do using "regedit.exe"? "RegSaveKey" will not work since it can only save all contents of a root key.

Read the documentation for RegSaveKey once again :
hKey <br />
[in] Specifies a handle to the key where the save operation is to begin, or any of the following predefined reserved handle values: <br />

From MSDN:
RegSaveKey
The RegSaveKey function saves the specified key and all of its subkeys and values to a new file.
Specifies a handle to the key where the save operation is to begin, or any of the following predefined reserved handle values...
So RegSaveKey also saves non-root keys.

and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Port 0x64 is the keyboard command port. 0xAD is the command that disables the keyboard. (0xAE renables it.) This is usually one of the first steps in enabling the A20 line in the old IBM AT and its clones to get access to memory above 1MB.

Hi,
I'm trying to display a toolbar with externales icons (from an executable). I can get the executable's icon, but I don't know how to assign it to an existant button in my toolbar... How to use the HICON to change the default image of a button of my toolbar 
Yann

Use GetIconInfo() to get the HBITMAP corresponding to the icon, then add that bitmap to the images available for the toolbar with TB_ADDBITMAP.

Ok, when I am using the send and recv commands
in the blocking mode I can break the blocking wait with the shutdown
command, but how can I break the blocking listen command?
I use the socket functions (listen, bind, recv...) in a single thread and
waiting with the listen function for some clients. If the user ends the application I
want to end the thread and for that I want to break the listen command!

Do you want your app to stop listening for connections?
Simply call closesocket(my_listen_socket)

Oh  thanks!
But does this also work to break the waiting recv function?

You don't do any recv() or send() with your listening socket!
You just accept connections and start I/O with that socket.
I you have an accepted connection and don't want the other side to receive more data from you (server), then just call shutdown(socket, SD_RECEIVE) or if you don't want the other side to be able to send data to you anymore you just pass SD_SEND as second parameter.
Is it clear? If not: I'm till here!

btw there is also Winsock's asynchronous mode (WSAAsyncSelect) if you just want to run one thread, it's nonblocking from design.
|

|

your problem is tricky !
when you listen the thread simply freezes ! right ?
you have to do this listening and accepting of clients on another thread :
unsigned _stdcall thAccept(void *lParam)
{
while(true)
{
SOCKET mSock=accept((SOCKET)lParam);
}
return 1;
}
SOCKET sock=create a server ;
UINT thAcc=0;
if(thAcc)
_endthreadex(thAcc);
_beginthreadex(NULL,0,&thAccept,(void*)sock,0,&thAcc);
return 1;
see ...

How to activate two windows?ie means floating windows or floatpallete?

Hi,
I've got myself a HWND to a window that I didn't create.
I want to be able to get back to the process that created the window, so that I can enumerate the Modules that it loaded.
Just not sure where to go.
<br />
<br />
HWND hWndAim;<br />
WNDCLASSEX myWin;<br />
<br />
hWndAim = FindWindow("Afx:400000:b:0:0:b0247", "Messages");<br />
GetClassInfoEx(????, "Messages", &myWin);<br />
<br />
Thanks very much

I don't know how to get the process handle from its window handle, however,
if you know the process name, then use my code
to get the process handle by its name.
Pview.exe shows the loaded dlls for processes.
I sure that you will find the source code of that utility.

DWORD GetWindowThreadProcessId(hWnd,lpdwProcessId)
this function returns the identifier of the thread that created the function
and if lpdwProcessId is not null it returns also the process id
|
|
|
|
|
Continue to my previous reply:
Forget about pview.exe.
Use EnumProcessModules of PSAPI.dll (supported under WinNT/win2K/WinXP).
Check the following Enumerating All Modules For a Process

What is the best way to determine the following:
1. Whether a device is installed (and whether it is installed correctly)? [most important question]
2. Whether a device is plugged in?
I am writing an install app, and for point one [most important question] i need to know whether any "found new hardware wizard" windows will pop up.
For point two, i have a function which includes the following code, but it seems to be a pretty rough way of doing it:
do
{
bResult = UpdateDeviceDriver();
} while(bResult != NO_ERROR);
Where UpdateDeviceDriver is a function which encapsulates the newdev ddk function UpdateDriverForPlugAndPlayDevices().

Hi guys,
If I set my timer to a value( say, 1 millisecond). Am I guaranteed to get the event service function called at frequency of 1kHz? My guess is not as following reason.
My impression is: if there is a higher priority process(system process) preempt the CPU at the time of timer interrupting, the service function is simply delayed to next available interrupt. Is it correct?
Thanks

HI,
timeSetEvent() creates and works in a new thread. So your understanding is correct. But the documentation doesnt says anything about its priority. If the CPU has some other processes more prior to this logically it will not trigger at that moment. There other options like WaitableTimer().
regards,
Sankaran

He was asking about timeSetEvent(), not WM_TIMER.

yes, I am asking multimedia timer, which Microsoft claims an "accurate" timer
