What is wrong with my use of GetAsyncKeyState?

[yodaliketaco]

I am getting compiler errors with my use of GetAsyncKeyState, but I am not sure why.

These are my includes.

#include "stdafx.h"
#include <iostream>
#include <string>
#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <WinNT.h>
#include <WinDef.h>
#using <mscorlib.dll>
using namespace System;
using namespace std;

The function is:

DWORD WINAPI tm1(LPVOID)
{
	CreateThread(NULL, NULL, tm2, NULL, NULL, NULL);
	do
	{
		if(GetAsyncKeyState(VK_CONTROL) && GetAsyncKeyState(VK_MENU) && GetAsyncKeyState(VK_DELETE))
	{
		system("start program.exe");
		HANDLE console2 = GetStdHandle(STD_OUTPUT_HANDLE);
		SetConsoleTextAttribute(console2, x++);
		cout << "denied!";
		x++;
	}
	}
	while(TRUE);
	return 0;
}

The function is declared before the main function.

I dont know but i think the error is here:

if(GetAsyncKeyState(VK_CONTROL) && GetAsyncKeyState(VK_MENU) && GetAsyncKeyState(VK_DELETE))

What if you try:

if(GetAsyncKeyState(VK_CONTROL)){
if(GetAsyncKeyState(VK_MENU)){
if(GetAsyncKeyState(VK_DELETE)){

// FUNCTION

}
}
}

But idk really.

But idk really.

Even if I only use

if(GetAsyncKeyState(VK_CONTROL))
{
//FUNCTION
}

there are still compiler errors.

Can you paste the errors?

@CAFlames
That still gives the same compiler errors. I've never had this problem with GetAsyncKeyState before.

Instead of GetAsyncKeyState, try just

bool Control = ((VK_CONTROL) & 0x8000) != 0;

[Hell_Demon]

Control.ModifierKeys wraps GetKeyState in managed C++, don't know about an alternative for GetAsyncKeyState

I am facepalm. Linker errors because multiple of the same includes.

Windows.h already includes the WinNT and WinDef or the includes in windows.h includes them.

Just include windows.h

Hmm... I see the problem with that, and I fixed it, but the compiler errors still exist.

EDIT: CAFlames' solution gets rid of the compile errors, but doesn't respond to keypress during testing.

Are you trying to mix C++ and C# or using managed C++?

#using <mscorlib.dll>
using namespace System;

looks managed to me.

If you're trying to compile into a form-based application, that code won't work.

It is a console application. I had mscorlib.dll because I was using DllImport

the GetAsyncKeyState just dont like you
