From Code Project articles i have coded a C++ DLL to be used as a global hook for C# projects. I have been successful in getting a global keyboard hook working. But when i try the same with a mouse hook, computer CPU goes to 100% and C# app gets a million messages that say the same thing. I am not the greatest C++ programmer. Am i missing something here? I think i have all the code parts needed?
Below is the code i am using (40+ lines):
#include "stdafx.h"
#include "hookdll.h"
#pragma data_seg("SHARED")
HHOOK m_mouseHook = NULL;
HWND m_hHookClient = NULL;
#pragma data_seg()
#pragma comment(linker, "/SECTION:SHARED,RWS") // linker directive
HINSTANCE m_hHookDLL = NULL;
const int GH_MOUSEOTHER = WM_USER + 4099;
BOOL APIENTRY DllMain(
HANDLE hInstance,
DWORD callReason,
LPVOID reserved)
{
switch (callReason)
{
case DLL_PROCESS_ATTACH:
m_hHookDLL = (HINSTANCE)hInstance;
break;
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}
extern "C" __declspec(dllexport) void InstallHook(HWND hWnd)
{
m_mouseHook = NULL;
m_hHookClient = hWnd;
// set mouse hook
m_mouseHook = SetWindowsHookEx(WH_MOUSE, (HOOKPROC)MouseHookProc,
m_hHookDLL, NULL);
}
extern "C" __declspec(dllexport) void RemoveHook()
{
UnhookWindowsHookEx(m_mouseHook);
}
LRESULT CALLBACK MouseHookProc(
int nCode,
WPARAM wParam,
LPARAM lParam)
{
if (nCode >= 0)
{
PostMessage(m_hHookClient, GH_MOUSEOTHER, wParam, lParam);
}
// pass control to next hook in the hook chain
return CallNextHookEx(NULL, nCode, wParam, lParam);
}

Hi,
is it possible for me to code a program in c++ to gather all URLs contained in a website/webpage?
or if not does anyone have a code to find URLs in a text file?
Does anyone have a sample code or a link that may give me information about this?
Your help will be appreciated. Thanks in advance

Use the following regular expression:
"<\\s*A\\s+[^>]*href\\s*=\\s*\"([^\"]*)\""
I've taken it from an example of boost regex library.

Thanks, but can u show me a more precise code?
|
|

If you haven't already done so, download the boost library. The regex library has an example ("regex_split_example_2.cpp"), that scans a file and returns a list of the URLs.

You are not making any sense, rephrase the question.

Of course you can use DLL with VC++.

Hi Everyone,
How can we write the commandline instructions in VC++? For example, i want to copy Excel file from one location to another location in another place(LAN). I have a copy button in my dialog. When i press the copy button, the excel file should be copied over to another location. Is it possible to do so?
Thanks in Advance.

system() if you directly use DOS commands.
otherwise, use CopyFile()

Thank you.
Is it possible to copy a file from one computer to other computer in a LAN using CopyFile().

looking at the MSDN[^], i think so
what you have to do for that is prepend the file name with \\<server>\...

int WINAPI function1(param);
int is the return value,function1 is teh function name,
then what does WINAPI do?
|
|
|
|
|
It's a calling convention for system functions. WINAPI expands to _stdcall.

It's a macro which expands to the appropriate calling convention. It's a macro so it can be defined differently on different platforms. On x86 based platforms it's __stdcall but on others it could be defined differently.
