how do i check which button is pressed ?

Hi All,

I have a quetion. I am using VC++ where i am getting values from the GUI controls using the DoDataExchange() function.

I have two buttons on my screen with ids IDOK and IDCANCEL, so my question is how do i make out in the DoDataExchange() function whether which button is pressed ??

Thank you in advance.

Why use DoDataExchange()?

WM_COMMAND sent to the window when you push the button. And it's ID is in the LPARAM.

msdn link for further information.

so you will be setting up something like this:

Code:

---

        case WM_COMMAND:
            switch(LOWORD(wParam))
            {
                case IDOK:
                    //do some stuff
                break;
                case IDCANCEL:
                    //do some some other stuff
                break;
            }
        break;

in your window process
