this's just look like when you use

File.OpenRead(filename)

error will be returned when the file is opening. In my case, if the file is still opening and user can modify the content while I am trying to obtain data. That's bad isn't it?

Because this is a global hook which will monitor all message before they really reach to target window. So I think It doesn't need inject the dll to the target window. But I will try. I took a round from google and know that many people have the same problem with me when they try to catch the WM_CLOSE. But I still cannot find the solution.

ok, KeyboardProc must be renamed to fnHookProc. But this is not the cause. This just a mistake when I copy from my code.

LRESULT CALLBACK LRESULT CALLBACK fnHookProc(int nCode,WPARAM wParam, LPARAM lParam)
{
PCWPSTRUCT msg = (PCWPSTRUCT)lParam;

   if(msg->message == WM\_CLOSE )
   {
	  //do somethings here
	
   }	
   return CallNextHookEx(\_hHook,nCode,wParam, lParam);

}

Hi all, I have written a program which can monitor a specific program when it was closed.I used hook to do it and everything seem be ok but the problem is that I cannot hook WM_CLOSE message. I have tried to use WH_GETMESSAGE, WH_CBT, WH_CALLWNDPROC. But all of them seem not work properly! here is my code:

hHook = SetWindowsHookEx(WH_CALLWNDPROC,fnHookProc,hInstDLL,tid);

DLLEXPORT LRESULT CALLBACK KeyboardProc(int nCode,WPARAM wParam, LPARAM lParam)
{

LPMSG msg = (LPMSG)lParam;

   if(msg->message == WM\_CLOSE )
   {
	  //do somethings here
	
   }

   return CallNextHookEx(\_hHook,nCode,wParam, lParam);

}

Hi, I have a form, and in this form, there's a button and a listbox. The question is how to add a item to the listbox using javascript when the user clicks on the button. This is my thinking but it doesn't work.

var lb = document.getElementById('mylist');

Thanks in advance
