Developers have always asked Microsoft to add more multithreading functions for VB, as does VB. NET. VB6 supports the establishment of multi-threaded EXE, DLL and OCX. However, the use of multithreading may be inaccurate. Therefore, VB6 only supports units that run multiple single threads. A unit is actually the space for code execution, and the boundary of the u

Since the age of VB6, the method of writing and registering COM + components was not very complex, but it entered. net World, the process of writing has become more complicated. Follow these steps: Assume that you want to write a data access component of the data table (tdmomenu) in the database ddmo. You need to generate a package named [kdmo1000] in the com

system. The difference between functions is that the parameters passed to them are different. In fact, VB supports polymorphism in two ways 1. Bind 2. multi-interface execution Inheritance: A major improvement of the. NET platform is the ability to use inheritance.

program scans the network by IP address to obtain the service status of each system. If the IP address does not correspond to the system, this IP address is ignored. For a system without services installed or services stopped, we run the nbtstat command in another thread to obtain the machine name, user name, MAC address domain, and other information, so that we can find the machine to solve the problem. Second, in order to save the scan results, we need a small

In the early days, the development tool I used was VB6, and the speed at which VB6 processed images was reflected in my imageshop software. Currently, I have switched to C # To study image algorithms. in C #, there are pointers, which make image processing more efficient. VB. NET used less than half a year at the beginning. Today, I have mastered the situation and made a simple description of

With Microsoft. the launch of the NET development platform has undoubtedly brought great news to countless VB developers, including no inheritance, ugly error capturing, no object pool, and no underlying development, it is followed by a complete OO-oriented feature, a wide range of class libraries that support XML. When someone prefers C #, C ++ developers are dismissive about it, but what is more important
