Windows SDK General: How to register Windows Common Controls in a Win32 application?

Q: How to register Windows Common Controls in a Win32 application?

A: You must register the control classes from the common control DLL ('comctl32.dll'):

1. include 'commctrl.h' header file;
2. link your project to 'comctl32.lib', e.g. using '#pragma' comment
3. call 'InitCommonControlsEx()'

Code:

---

#include <windows.h>
#include <commctrl.h>
#include <resource.h>

BOOL CALLBACK DialogProc(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam);

void RegisterCommonControls();

#pragma comment(lib, "comctl32.lib")

void RegisterCommonControls()
{
  INITCOMMONCONTROLSEX iccex;

  iccex.dwSize = sizeof(INITCOMMONCONTROLSEX);
  iccex.dwICC  = ICC_TREEVIEW_CLASSES  // tree view and tooltip control classes
                  | ICC_LISTVIEW_CLASSES; // list view and header control classes
                          // see INITCOMMONCONTROLSEX in MSDN for a complete list
  InitCommonControlsEx(&iccex);
}

int APIENTRY WinMain(HINSTANCE hInstance,
                    HINSTANCE hPrevInstance,
                    LPSTR    lpCmdLine,
                    int      nCmdShow)
{
  RegisterCommonControls();
  INT_PTR nRet = DialogBox(hInstance,                    // handle to module
                          MAKEINTRESOURCE(IDD_DIALOG1), // dialog box template
                          NULL,                        // handle to owner window
                          DialogProc);                  // dialog box procedure
  return 0;
}
