Description: Displaying a large bitmap file on a dialog box, in its original size, is quite difficult in the VC++ environment. However, it is possible to display a large bitmap to a predefined area of the dialog by using the StretchBlt( ) function.The major disadvantage of this is that the clarity of the image will be lost. Check out this article for displaying large bitmaps into the desired area of your dialog box in its original size with a scrolling technique used to show the entire bitmap.
滚动显示位图
在VC++环境下，在一个对话框中显示一个原始尺寸的大小的位图文件相当是困难的。然而,通过使用 StretchBlt()函数一个给定的区域显示一个大的位图是可能的。主要的缺点是图像将会失真。看了这篇通过卷动技术显示整个位图技术的文章，你将能够以它的原始尺寸在给定对话框的区域内显示一个大位图。

Description: 其实原理就是捕获屏幕画面然后再把图像传给客户机。原理很简单：
1、先利用hdc=GetWindowDC(NULL) 得到桌面的hdc
2、memhdc=CreateCompatibleDC(hdc) 根据桌面的hdc创建一个和屏幕相同的内存DC
3、StretchBlt(memhdc,0, 0, nWid,nHei, hdc, 0, 0,nWid,nHei, SRCCOPY) ，把屏幕的图像复制到内存DC这时你已经在内存中得到了屏幕的图像了。这是设备相关的DDB图像，如果希望转换成设备无关的DIB图像，只要在DDB图像前创建一个标准的BITMAP文件头就可以了（DDBtoDIB( bitmap, BI_RGB, pal )）。
4、得到图像数据（如果考虑速度的话可以把图像压缩）
5、数据传输（远程监控）
“在这里，我们先来看看截获当前桌面是如何实现的。关于远程捕获，只要在下面的基础上加上网络传输部分就OK了。下面介绍的是捕获桌面技术的基础，具体截屏代码如下：
-In principle is to capture screen picture then pictures to the client. Principle is very simple:
1, first using HDC detected by FCM (NULL) GetWindowDC = Get the desktop HDC detected by FCM
2, memhdc = CreateCompatibleDC (HDC detected by FCM), According to the desktop HDC detected by FCM create a same memory DC and screen
3 and StretchBlt (0, 0, memhdc, nWid, nHei, 0, 0, HDC detected by FCM, nWid, nHei SRCCOPY) , The screen, the image to the memory when you are already in memory DC got screen image. This is related to the equipment, if hope DDB image converted image of device-independent DIB in DDB images, before creating a BITMAP standard file header can (DDBtoDIB BITMAP, Pal, BI_RGB ().
4 and image data (if consider speed can put the image compression)
5 and data transmission (remote monitoring)
"Here, we ll look at how the desktop is intercepted. About remote capture, just below the basis and network transmission parts with respect to OK. Here is the foundation, the desktop
