C ++简单的钩子和隐藏命令提示符

Question

I am new to C++ and have just learned about hooks so I have a C++ program which runs a function when a KeyEvent occurs:

LRESULT WINAPI KeyEvent(int nCode, WPARAM wParam, LPARAM lParam)
{  
  //Do C++ stuff
}

This is my only hook so far.

However I want to hide the command prompt which pops up when executing my code.

I was told I can use this snippet to hide it:

HWND Stealth;
AllocConsole();
Stealth = FindWindowA("ConsoleWindowClass", NULL);
ShowWindow(Stealth,0);  

However if I place it in the hook it will not hide the prompt until a key is pressed (not ideal) and if I place it above the hook (near top of program) I get an error...

So my question is, is there any other types of hooks which I can place the snippet in to hide the command prompt once program is ran? -Or is there any other way like my snippet to hide command prompts which I can use?

Thanks alot.

Answer 1

Change your project settings to build a "GUI" application (this changes a few linker options), and provide a WinMain entry point instead of main. That way there will be no console window.

Answer 2

You can always use the WM_CREATE msg to do what you want. And inside it call:

if(MSG == WM_CREATE)
  ShowWindow( GetConsoleWindow(), SW_HIDE );

That might work for you, and if you need the console again just change SW_HIDE to SW_SHOW.

Usually you would use a switch statement for the message type.
