C++ make the mouse move on the ''VK_LBUTTON'' key C++

[isvkt]

my code is simple, it just makes the mouse move down but it moves automatically, i want it to move when i press the ''VK_LBUTTON'' key I tried to put ''if(GetKeyState(VK_LBUTTON)'' but it is closing when I open

 

int main(void)
{
	if (!mouse_open()) {
		printf("[-] failed\n");
		return 0;
	}


	for (int i = 0; i < 32; i++) {
		Sleep(100);
		printf("[+] moving mouse\n");

		mouse_move(0, -10, 0, 0);
	}


	mouse_close();
}

Hi dear @isvkt

 

I guess you are trying to use Win32, right?

 

Since Win32 is an event driven API, it will tell your program that the left mouse button was pressed with an event signal, witch you need to process with a Win32 event loop

 

Something like this:

#include <windows.h>

  
int WINAPI WinMain(HINSTANCE hInstance,
                   HINSTANCE hPrevInstance,
                   LPSTR     lpCmdLine,
                   int       nCmdShow)		// This is the "main()" function in win32.
{
	MSG msg;	// Event structure that windows will send to you program (Mouse button down, close, resize etc).

  	// Event loop will send all the messages to a callback function to be processed.
  	while(GetMessage(&msg, NULL, 0, 0) > 0)
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    return msg.wParam; // "main()" returns the event info. 
}


// This is the callback function where you will process the events.
LRESULT CALLBACK WndProc(HWND hWnd,
                          UINT uMsg,
                          WPARAM wParam,
                          LPARAM lParam)
    switch(uMsg)
    {
  	// The event is a mouse left button pressed.
        case WM_LBUTTONDOWN:
        {
        	// Your code to move mouse cursor goes here.
        }
        break;
        
        default:
        // In case of any other event, let Windows process it.
            return (DefWindowProc(hWnd, uMsg, wParam, lParam));
        break;
    }

    return 0;
 }

 

Hope this helps you
