BackgroundAs with the offline tiling scheme, it is also designed to address mobile speed and traffic issues, but not just this. The traditional presentation of vector data is generally divided into two scenarios:
Dynamically capture vector data images from the WMS (vector data is returned from
gave a picture of the image into a discrete diagram after the organization of the file, which shows you in this graph, the organization of the file is in accordance with the tile level, row, column number to organize. In fact, the same is true of the organization style of the compact tile (Bundle), but it also has a series of conversions after the number of rows, such as reading the index file to find the offset in the file, which I will discuss with you in a later chapter. Also, standard
to catch exceptions
DECLARE EXIT HANDLER for not FOUND SET @info = ' no_such_table ';
Method VI: Use SQLEXCEPTION to catch exceptions
DECLARE EXIT HANDLER for SQLEXCEPTION SET @info = ' ERROR ';
3 Integrated Examples
Create a table, set the primary key for the table, and see where the execution is if you do not define exception handling and define exception handling.

Today a friend asked me how to implement the event in the program. So I summed up the HA sent out. To understand the event, you first need to know what the delegate is. Delegate in C # to allow developers
Passes a method in one object to another object that can call the method's class. For example, a method in class AC can be add[if the method is included in a delegate and passed to another class WMS. At this time the class
