Missing checkbox...

I have 3 buttons on my window and 1 checkbox. I get no errors
when my program compiles/links but when it runs the checkbox is
no where to be found.

Here's my code:

Code:

---

//in my message handler

case WM_CREATE:

CreateWindowEx(0,"Button","End Turn",WS_CHILD | WS_VISIBLE
| BS_DEFPUSHBUTTON,245,50,60,30,hwnd,
NULL,hInstMain,NULL);

CreateWindowEx(0,"CheckBox","CheckBox",WS_CHILD |
WS_VISIBLE | BS_CHECKBOX,245,90,60,30,hwnd,
NULL,hInstMain,NULL);

---

Any ideas of what I'm doing wrong? The MSDN library wasn't too helpful. Thanks in advance for any advice.

You are passing the wrong class name to the CreateWindowEx function it should be "button" not "checkbox", b/c a checkbox is a type of button. Just change that and it should work fine.

Thanks, xds4lx. That fixed that problem, but now I've got a new one. How do I change the state of the checkbox. I can identify when it was clicked on (by checking the (HWND)lparam value when a WM_COMMAND message comes in) but I don't know how to "check/uncheck" the checkbox.

I read through the MSDN help for it and tried the CButton::Create(blah,blah,blah) but it gave me errors like:

error C2653: 'CButton' : is not a class or namespace name
error C2065: 'Create' : undeclared identifier

I've tried declaring an instance of the CButton class with:
CButton cbCheckBox;

And then using:
cbCheckBox("Test",WS_CHILD|WS_VISIBLE|BS_CHECKBOX,
&rcCheckBox,&hwnd,NULL);

This gives me errors:
error C2146: syntax error : missing ';' before identifier 'cbCB'
error C2501: 'CButton' : missing storage-class or type specifiers
error C1004: unexpected end of file found

Does anyone know of a good tutorial for using Command Buttons/Checkboxes, etc. WITHOUT using MFC?

Again, thanks.

Ok, when you are processing the WM_COMMAND message you should do something like this:

Code:

---

....
case WM_COMMAND:
{    switch(LOWORD(wParam)) // which control (button or otherwise
    {                      // caused the message
          case MY_CHECKBOX: // this should be the id you used when
          {                // creating your "button"
              switch(HIWORD(wParam))
              {  case BN_CLICKED:
                {  SendMessage(hButton, BM_SETCHECK, 1,0);
                    // The params are the control (or buttons hwnd,
                    // the message to send, this case button set
                    //check, 1 to tell it to check, 0 to uncheck, and
                    //the last param should always be a 0!, or you
                    //can use BM_GETCHECK to check the state of the
                  //button, just look up "Button Messages in msdn"
                    return(0);
                  }
                  default:
                    return DefWindowProc(hWnd,Msg,wParam,lParam);
              }
            return(0);
            }
        }

Thanks again, xds4lx! It actually makes sense now. :D
