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。 来源: http://www.codeguru.com/bitmap/ScrollBitmap.html

这是关于文件操作的一个题，由题意可知，该题解决起来应该分为三个部分。第一部分即从in.dat中读入数据，第二部分即实现排序的算法，最后应该实现将排序的结果输出到out.dat中。

随机性发生器、冒泡分类和混洗一组12张牌的演示程序。 Demonstrates the use of a randomizer, bubble-sort and an array to "shuffle" a deck of 12 cards. I put it here for those of you who are trying to figure out how to shuffle with a randomizer without having the same card appear two-or-more times.

CBC下写的串口编程，API函数实例 I wish this site had been around when I was trying to figure out how to make serial communications work in Windows95. I, like many programmers, was hit with the double-whammy of having to learn Windows programming and Win95 serial comm programming at the same time. I found both tasks confusing at best. It was particularly frustrating because I had, over the years, written so much stuff (including lots of serial comm software) for the DOS environment and numerous embedded applications. Interrupt driven serial comm, DMA transfer serial comm, TSR serial comm, C, assembler, various processors... you name it, it had written it. Yet, everything I knew seemed upside-down in the message-driven-callback world of Windows.
