C++ Hotkey Toggle Framework

Haven't posted in a while.  Been using this for a lot of game bots lately, just a simple hotkey toggle in C++.

1:  void toggler()  
2:  {  
3:       bool toggle=FALSE;  
4:       if (RegisterHotKey(NULL, 1, MOD_ALT|MOD_NOREPEAT, 0x42)) // B  
9:       {  
10:           cout << "Hotkey Registered" << endl;  
11:      }  
12:     
13:      MSG msg = {0};  
14:    
15:      while(1)  
16:      {  
17:           if(toggle==TRUE)  
18:           {  
19:           Sleep(500);  
20:           //<CODE GOES HERE>  
21:           }  
22:                else  
23:                     Sleep(500);  
24:           while (PeekMessage(&msg, NULL, 0, 0, 1) != 0)  
25:           {  
26:                toggle = !toggle;  
27:           }  
28:      }  
29: }  

Lines 7/8 set the hotkey options, this has MOD_ALT and MOD_NOREPEAT so it doesn't spam the hotkey when I press it. 0x42 is the VK key code, which you can find here: https://msdn.microsoft.com/en-us/library/windows/desktop/dd375731(v=vs.85).aspx Press once to toggle it on, again to switch it off. Makes auto-clickers, for example, much easier than having to run the program every time.
