提前致谢.任何人都可以帮助解决以下问题.

我做了一个套接字应用程序，它从车辆跟踪unit.one 示例接收数据，如下所示:

Dears,

Thanks in advance. Can anybody help to solve my problem which is described below.

I did a socket application which is receiving data from a vehicle tracking unit.one example as follows:

Example- %%D1,100,0,0004[data...][0d0a]

Head -   %%D1
Amount of data package -100
The data package No.  - 0
Data Length -1024  (0004 (low bit in front, high bit in back) 0004= 0x0400=1024;)

data- Original Picture data -1024(maximum)
Tail -0x0d0a
Data in hex

从上面的示例中，我想提取图片数据并将其存储到SQL表中. SQL表columname 是映像，datatype 也是映像.之后，我想将此图像列显示到aspx页面.

尽快寻求帮助.

From the above example, I want to extract picture data and need to store into the SQL table. SQL table columname is image and datatype is also image. After that, I want to display this image column to an aspx page.

expecting help asap.
