本文介绍如何在Win32SDK程序中通过修改窗口样式来去除窗体的边框和标题栏等元素，并提供了一个示例程序代码。

在Win32 SDK程序中，Create时创建一个一个窗体。欲去除其边框标题栏等属性，宜在WM_CREATE消息中写，或者在子窗体（例如按钮）的单击消息中以

达到目的。
全部程序如下：

// ContactListDemo.cpp : Defines the entry point for the application.
//

#include "stdafx.h"
//#include "windows.h"

#define ID_BUTTON 1;
HWND hButton;

LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);
TCHAR szAppName[]=TEXT("ContactListDemo");

int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR     lpCmdLine,
                     int       nCmdShow)
...{
     // TODO: Place code here.
    int error;
    HWND hwnd;
    MSG msg;
    WNDCLASS wndclass;

    wndclass.style =CS_HREDRAW|CS_VREDRAW;
    wndclass.lpfnWndProc =WndProc;
    wndclass.cbClsExtra =0;
    wndclass.cbWndExtra =0;
    wndclass.hInstance =hInstance;
    wndclass.hIcon =LoadIcon(NULL,IDI_APPLICATION);
    wndclass.hCursor =LoadCursor(NULL,IDC_ARROW);
    wndclass.hbrBackground =(HBRUSH)GetStockObject(WHITE_BRUSH);
    wndclass.lpszMenuName =NULL;//szAppName;
    wndclass.lpszClassName =szAppName;

    if(!RegisterClass(&wndclass))
    ...{
        MessageBox(NULL,TEXT("ContactListDemo"),
            szAppName,MB_ICONERROR
            );
        return 0;
    }
    error=::GetLastError ();

    hwnd=CreateWindow(szAppName,TEXT("ContactListDemo"),
    WS_OVERLAPPEDWINDOW /**//*&(~(WS_CAPTION | WS_BORDER|WS_SYSMENU|WS_THICKFRAME|WS_MINIMIZEBOX|WS_MAXIMIZEBOX ))*/,
    CW_USEDEFAULT,CW_USEDEFAULT,
    CW_USEDEFAULT,CW_USEDEFAULT,
    NULL,NULL,hInstance,NULL);

    error=::GetLastError ();

    ShowWindow(hwnd,nCmdShow);
    UpdateWindow(hwnd);

    while(GetMessage(&msg,NULL,0,0))
    ...{
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    return 0;
}

LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wParam , LPARAM lParam)
...{
    switch(message)
    ...{
    case WM_CREATE:
        //SetWindowLong(hwnd, GWL_STYLE,GetWindowLong(hwnd, GWL_STYLE) &
        //    (~(WS_CAPTION | WS_BORDER|WS_SYSMENU|WS_THICKFRAME|WS_MINIMIZEBOX|WS_MAXIMIZEBOX )));

        hButton=CreateWindow(TEXT("button"),TEXT("CHANGE WINDOW STYLE"),WS_CHILD | WS_VISIBLE,
                /**//*CW_USEDEFAULT,CW_USEDEFAULT,
                CW_USEDEFAULT,CW_USEDEFAULT,*/
                20,20,200,50,
                hwnd, (HMENU)1,
                ((LPCREATESTRUCT)lParam)->hInstance,NULL);

        return 0;

    case WM_DESTROY:
        PostQuitMessage(0);
        return 0;

    case WM_COMMAND:
        switch(LOWORD(wParam))
        ...{
        case 1:
            SetWindowLong(hwnd, GWL_STYLE,GetWindowLong(hwnd, GWL_STYLE) &
                (~(WS_CAPTION | WS_BORDER|WS_SYSMENU|WS_THICKFRAME|WS_MINIMIZEBOX|WS_MAXIMIZEBOX )));
            //MessageBox(hwnd,TEXT("Clicked Button"),TEXT("Test"),MB_OK);
            break;

        default:
            break;
        }
        break;
    }
    return DefWindowProc(hwnd,message,wParam,lParam);
}
