Cant get Virtual Keys to work with a switch statement

[h4344]

Im simply trying to have it so if a user presses for example F1 then the program does whatever i have set in the switch statement. I have very little experience when it comes to working with windows so far and there are pretty much no tutorials that tell you how to do something this simple (yes i actually looked).

(This is just an example so if anything is clearly wrong dont be surprised)

#include <iostream>
#include <cstdlib>
#include <windows.h>
#include <string>


int main(){

    string a;
    
    switch(a){
        case:
            VK_F1:
                cout << "Whatever" << endl;
                system("pause");
                break;
    }
}

I pretty much just need help making this work.

It's just a matter of knowing the right term to search for. There are tons of tutorials and there are a few ways to do this. One of them is with GetAsynKeyState(VK_F1);

Another way, in windows, is to process the WM_KEYDOWN message.

Note that 'VK_F1' by itself is just a number. It only has meaning when it is used as a flag for GetAsynKeyState() or similar function.

Ya i saw the GetAsynKeyState before but wasn't sure if it was what i needed. Thanks though ill look into that some more

Try this:

#include <windows.h>
#include <stdio.h>

int main()
{
    while(1)
    {
         if(GetAsynKeyState(VK_F1))
         {
          printf("Helllllo!!!! =D");
          }
     }
     return 0;
}
