The structure of a grayscale image consists of four parts: File Header, BMP Information header, color palette, and BMP data content. The gray-scale palette has a total of 256 rgbquad structures and stores the gray-scale values ranging from 0 to 255. Each rgbred, rgbgreen, and rgbblue has the same component values.

The previous section describes how to directly operate the framebuffer of wince. Here we will introduce a method to display BMP images in resources by writing framebuffer. Compare it with using GDI to see if direct read/write framebuffer can improve efficiency?
The key code is as follows:

EJB has two main types: BMP (bean managed persistence) and CMP (container managed persistence), which have their own advantages and disadvantages.
BMP is used to call database JDBC in bean. That is to say, in your entity bean, SQL statements such as "insert .. "or" select .. ", and use datasource to obtain a database resource and connection to directly add, delete, and modify the database.
CMP is automatica
============ Problem Description ============Recently doing something about the jni development of Opengles, met some problems, before loading the bitmap in the Java layer and then mapping is easy, when the corresponding code is ported to the JNI layer, the other is not a problem, but the bitmap loading encountered a problem, Is there a great God guidance on how to load BMP graphs into code in the JNI layer and then go to map??I really developed it in

Method 1:
1) modify the picture control attribute
2) directly associate with the image: Set the image attribute
3) change the type to bitmap.
Method 2: (pictureex online search)
1) Add the control variable as a pictureex object.
2) directly m_pic1.loadbitmap (idb_bitmap1 );
Example:
1. Associate the picture control object: m_stpict
On Saturday and today, the storage and display of images in the database were realized. Although the time was a little long, it was still realized. The following documents are useful.

Step 1: First, open a bitmap file. The controls used here use the picture control, which is the one on the right of the control icon. Change the ID number to idc_picture and define two member variables.Char * m_char; // image file pointerD
