DialogBox()是另一種用來建立Dialog的方式，有別於CreateDialog()，DialogBox()是屬於Block方式呼叫，直到Dialog結束後，才會從DialogBox()繼續往下執行，而使用DialogBox()建立的Dialog，必須使用EndDialog()關閉Dialog視窗

main.c

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

INT_PTR CALLBACK DlgProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    DWORD dwID = wParam;

    switch (uMsg) {
    case WM_COMMAND:
        if (dwID == IDOK) {
            EndDialog(hWnd, 0);
            return TRUE;
        }
        break;
    }
    return FALSE;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
                   LPSTR lpCmdLine, int nCmdShow)
{
    DialogBox(hInstance, MAKEINTRESOURCE(IDD_MAIN), NULL, DlgProc);
    ExitProcess(0);
    return 0;
}
