TOPGP combobox Dynamic drop-down list

Used to know the TOPGP, the drop-down list on the screen is written dead on the screen file, each program must be manually to maintain it, very disgusting very troublesome,Ding Jie also found this problem, in the T100 above on the use of the dynamic way to display, the specific way is to maintain a basic file on the front end, and then the program to crawl the data on the base file dynamic display to the drop-down list. This is really a lot easier to do. In fact, TOPGP is also supporting this wa

Display in the middle of the screen, press ESC to change the color of the character

main program must change the entry address of the Int 9 interrupt routine in the interrupt vector table to the entry address of the interrupt handler we wrote. Then when invoking the original int 9 interrupt routine in the new interrupt handler, the entry address of the Int 9 interrupt routine in the interrupt vector table is not the address of the original int 9 interrupt routine. So we cannot call directly with the INT directive. To invoke the original interrupt routine in the new interrupt r

Modular Java: declarative Modularization

values are limited, and the installer tends to select a single number as the startup level, it cannot ensure that you can solve the problem only by starting the order. It is worth noting that bundle with the same startup level is independently started (possibly in parallel). Therefore, if you have a bundle with the same startup level as log service, no one can guarantee that the Log service is ready as needed. In other words, the startup level can solve most problems, but not all problems.Decla

JAVA Database Connection Methods

component that supports creating database connection pools and managing connections. When using this method for database connection, you need to import c3p0-0.9.1.2.jar. In addition, specific database connection parameters, such as url, username, password, minimum connections, and maximum connections ..... And other information can be configured in the xml configuration file or created through program encoding. Spring supports the database connection pool of c3p0. Therefore, it supports configu

Usage of Si and DI registers

Sidi is a register with similar functions between 8086cpu and BX. Sidi cannot be divided into two 8-bit registers. The following three sets of commands implement the same functions: (1) mov BX, 0 MoV ax, [BX] (2) mov Si, 0 MoV ax, [Si] (3) mov Di, 0 MoV ax, [di] The following three sets of commands also implement the same function: (1) mov BX, 0 MoV ax, [bx + 123] (2) mov Si, 0 MoV ax, [Si + 123] (3) mov Di, 0 MoV ax, [di + 123] Use the Si and DI registers to implement the 'Welcome to MASM!

Use of SQL DataAdapter in C #

SqlDataAdapter overview SqlDataAdapter is a bridge between the dataset and SQL Server that is used to retrieve and save data. SqlDataAdapter maps Fill by using the appropriate Transact-SQL statement on the data source (it changes the data in the dataset to match the data in the data source) and Update (it can change the data in the data source to match the data in the dataset) To provide this bridging. When SqlDataAdapter fills the dataset, it creates the necessary tables and columns for the re

It is important that you can easily navigate to get the relevant information, such as province.getcityrows () can get all the cities below the province, And Province.countryrow can get the country where the province is, is it more convenient to check the database than before through the foreign key? With this kind of navigation comes the convenience of the Cascade update, such as the deletion of the paren
