you use VB. NET, because there are two facts worth noting:
Office uses VBA. At least we will still see it in office 12. Do you think the installation volume of Visual Studio has exceeded the installation volume of office? Select VB. net makes it easy for you to continue some habits, concepts, and ideas of VBA, even t

, because all threads of the same process share the same memory, no special data transmission mechanism is required, and no shared storage area or file is required, this makes it easier to solve problems such as coordinated operations and operations between different tasks, data interaction, and resource allocation.

1. Introduction
1.1 process and thread and application domain
In the operating system, a process is defined as a running instance of an application, which is a dynamic execution of the application. A thread is the path for executing the internal program of a process and an execution unit of the process. Basically, a thread is the simplest unit of code that can be scheduled by the system. It is responsible for executing the program code contained in the address space of the process. See figure 1.
assembly. VB.net absorbs many excellent components of C ++ and VB and has many innovations. It can be considered that Visual Basic 7.0 is an upgraded version of VB, and its runtime is based on CLR (common ).Language Runtime) and virtual machine .. Net is short for visual studio.net .. Net = visual studio.net. Second,
When talking about vb.net can make people think of VB, is really VB and vb.net like a mother born of a pair of twins, long basic identical, the use of the rules are mostly the same. Even so, the two are fundamentally different: vb.net is object-oriented and VB is process-oriented. It is like twins who are similar in nature, but the temperament they acquired is qu
When a program launches an external application, we usually use the WIN32 application programming interface or VB Shell function to solve it. Now, there's a System.Diagnostics.Process class in the. NET Framework that you can use to do this, and you'll find it much easier.
In traditional VB programs, you can use the She

"It seems that you have mastered the basic steps of interface operations ." I am so happy with the comments from Da li. "I would like to sum up that the main reasons for using interface inheritance instead of class inheritance are: when the application requires a lot of irrelevant object types to provide some function, the interface is more adaptable. The interface is more flexible than the base class, because y
terms rather than the member names when they are specifically encoded. I like to use the term "structors" to refer to constructs and destructors. In the VB6 language, the specific "structors" is Class_Initialize and Class_Terminate. Under VB.net, the Class_Initialize method is renamed to New, and Class_Terminate is finalize.
The programmer is not allowed to add parameters to the Class builder according to the VB6 implementation restrictions. However, VB
