在Windows操作系统中,当用户按下"PrintScreen"按钮后,Windows自动将当前屏幕的图像拷贝到系统剪贴板中,这时可以通过"画笔"这个小程序将剪贴板中的内容保存成图像文件,可以看出,如果需要将当前屏幕保存下来还是比较麻烦的,能否可以自己编写一个应用程序,自动将当前屏幕的内容保存到一个图像文件中去呢?这个答案是肯定的,本实例应用程序就是利用通用的热键管理DLL库实现的热键功能,在收到热键通知后截取屏幕的内容并保存到bmp文件中。例如我们设置图片保存路径为c:\,热键为F9 + Control,然后按Change按钮设置好热键,那么当我们按下CTRL+F9后,当前界面将以BMP图像文件的格式被保存在C:\目录下。程序编译运行后的界面效果如图一所示:
IxaF*4JG mI'&!@WG 一、实现方法
+E-CsNAZ*" 3?e~J"WXC5 热键管理DLL实际上是一个键盘钩子,由它来监视系统的键盘事件。如果有和程序登记符合的按键组合就通知该程序的窗口。为了应用方便,本实例把它做成了一个标准的管理库来为其它的程序通过热键服务,它有两个输出函数:AddHotkey()和DeleteHotkey(),程序只需要调用这两个函数就可以了,如果编译之后不用改变热键,则只需要AddHotkey就可以了。DLL中的所有的全局变量都放在一个共享段中,定义如下:
PUmgcMt 7~Z(dTdSG #pragma data_seg("shareddata")
==AmL]* HHOOK hHook =NULL; //钩子句柄
L%jIU<?Z7 UINT nHookCount =0; //挂接的程序数目
3JEg3|M( static UCHAR HotKey[MAX_KEY] = {0}; //热键虚拟键码
qe'RvBz static UCHAR HotKeyMask[MAX_KEY] = {0}; //组合掩码, control=4,alt=2,shift=1
XK&G `cJ[ static HWND hCallWnd[MAX_KEY] = {0}; //window handle associated with hotkey
q_cP<2`@V static int KeyCount =0;
.$fSWlM; static UCHAR MaskBits =0; //00000 Ctrl=4 & Alt=2 & Shift=1
6aLRnH"Ud #pragma data_seg()
+ZOKfX RsYMw3)G 关于共享段,有几点重要的说明:一是必须在链接选项里指定该段为共享:一种方法是在project->settings->link->object/library中加上/section:shareddata,rws;第二种方法是在def文件的sections里加上一句shareddata read write shared;第三种指定共享段的方法在程序里加上一句#pragma comment(linker,"section:shareddata,rws")。二是所有的变量必须初始化,否则链接程序会把它放到普通数据段。三是如果不初始化变量,需要在段外用"__declspec(allocate("shareddata")) 变量类型 变量名"的方式定义。

xaMDec V I@cw=_EQL 抓图程序是一个基于对话框的程序,它在建立对话框的时候调用前面的DLL,登记热键,因此需要将hook.lib添加到工程里,在程序里给出两个DLL函数的定义,也可以写个头文件,再包含进来以下代码:
0Qt!w( HoGYgye= BOOL __declspec(dllexport)__stdcall AddHotkey(HWND,UCHAR key,UCHAR mask);
=
j1Jl^[ BOOL __declspec(dllexport)__stdcall DeleteHotkey(HWND,UCHAR key,UCHAR mask);
H
-Mb:4 kK[4uQQ 为了添加应用程序对热键通知事件的响应,程序中用的办法是重载WindowProc()函数,该函数代码如下:
S0^a)#D & v76Gwu$d LRESULT CCaptureDlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
|UXSUP
@s {
( eTrqI` if(message==WM_HOTKEY&&lParam==WM_KEYDOWN)
GTP'js {
DhyR //lParam表示是按下还是松开,如果有多个热键,由wParam来区分
h3?>jE=H SaveBmp();
[H}>
2Q return FALSE;
_i05'_ }
FCEy1^u …… //其它处理及默认处理
"2cOS PpQL }
0caZ_-zU Lnh=y2 kB
8^v7o 将屏幕图像保存到BMP文件中的任务是由函数SaveBmp()来完成的,具体实现参见代码部分。另外为了顺利实现屏幕抓图,程序中还实现了"托盘"功能,由于这一部分本书在实例中已经专门介绍过了,所以不再赘述,读者朋友可以参考相关实例。
6.D|\;9{c ZxF`i>/h 最后需要提醒读者朋友们注意的是,源程序的编译与使用时要先编译hook.dll并将其放在系统目录(win2000/NT是system32,98/ME是system),然后编译对话框程序运行即可。
Tv=lr6t8 r2=@1=?8 二、编程步骤
l_h:S`z. hq=;ZI 1、 启动Visual C++,生成一个DLL项目和一个基于对话框的应用程序项目,并将两个项目分别命名为"Hook"和"Capture";
FzInIif <V&0GAZ 2、 在"Hook"项目中导出AddHotkey()、DeleteHotkey()函数;
b>uD-CSA }DhqzKl 3、 在"Capture"项目中按照图一所示设置对话框的界面,具体设置参见代码部分;
gNCS*a E8PDIjp 4、 使用Class Wizard在"Capture"项目中添加按钮的鼠标单击消息响应函数,并重载对话框的WindowProc()函数;
{MgRi7 $mQ0w~:@ 5、 添加代码,编译运行程序。
