在很多管理信息系统的窗体都有一些共同点:可以通过框架菜单打开各种类型的视图窗口,而这些视图窗口具有MDI的一些特点,可以在框架窗体中最小化最大化还原等,并且点击菜单只能产生一个窗口(象SDI)。这种形式的窗口设计给人与一种条理感。于是我用VC6.0尝试创建这种窗口,现将整个过程为大家写下来,这里应含有MFC的一些内幕技术。
-Management information systems in many of the forms have some common elements: the menu can be opened through the framework of various types of view window, which has a view window MDI some of the features, you can form in the framework of maximizing the smallest reduction, etc., and Click on the menu can only have a window (as SDI). This form of window design gives people with a sense of well-organized. So I use VC6.0 attempt to create such a window, now the whole process for everyone to write down here should contain a number of insider MFC technology.

微软的SQL SERVER数据库的Image、text等字段都属于二进制的大对象。这些对象的存取和其他轻型对象略有不同。
微软.NET Framework的System.IO命名空间下给我们提供了一个FileStream文件流类。我们可以使用这个文件流对二进制大对象轻松进行读写。
我实现了一个简单的WinForm程序,这个程序通过点击“Open”按钮选择一个bmp或者jpg文件,并显示在图形控件PictureBox中。通过“Save”按钮存入数据库。点击“View”CheckBox可以切换到浏览状态,观看存入数据库的图片。
由于对二进制大对象使用的流操作,所以对于任何文件都具有通用性。读写文本文件也可以这么做。
-Microsoft s field and so on SQL SERVER database Image, text all
belongs to binary the big object. These objects deposits and
withdrawals and other light objects have the difference slightly.
MicrosoftNET Framework System.Under the IO naming space provided a FileStream document to us to flow
the kind. We may use this document to flow to the binary big object
with ease carry on read-write. I have realized a simple WinForm
procedure, this procedure through clicks on "Open" the button to
choose bmp or the jpg document, and the demonstration controls in
PictureBox in the graph. The button stores the database through
"Save". Clicks on "View" CheckBox to b
