I have been hiding from the first day, and I have to skip the 15th day. I finally want to upgrade a VB6 project to VB. NET. On my colleague's computer, there is no problem with the upgrade.

Search online for information about how to use C # To develop ActiveX ControlsArticleIt basically seems to be an article in the cited blog Park. But that article is used in IE. However, I have tried it. If it cannot be referenced in VB6, the system prompts that it cannot be registered as an ActiveX control. Later, we found that Microsoft has provided a toolkit "Microsoft InterOP forms Toolkit 2.0" to conveniently implement this function. After the i

Many companies I have worked for are selecting VB. net, as their core development tool, has gone through a long period of time. One of their major concerns is that if they do not use the C # language, they cannot develop pure. net Framework code. There are two main reasons for them to come to the conclusion that, first of all, due to the running restrictions of

For a long time, VB has been ridiculed by some people because of its lack of perfect object-oriented support, lack of efficient error handling mechanism and poor performance. Vb. NET will completely change this situation. However, VB. NET in these aspects of the improvement

------------------------------------------------------------------- Q: I heard that learning Java will use vb.net. A: Have you ever seen a Java programmer write a vb.net program or article (a lot of abusive articles)? On the contrary, VB Programmer wrote the article of C #, quite good.

VB.net can implement many functions that C # cannot do, such as when statement, optional parameter, local static variable, object instance access static method, handles binding event, on error handling exception, Object direct late binding, and so on. VB and C # belong to the same. NET language, compiled with the same CIL, but why VB support a lot of interesting

benefits. In many cases, vb.net's object-oriented nature and the inherited performance of implementations help you create specific types of functionality more easily and quickly than in previous versions of VB. However, you don't have to use inheritance or other. NET functionality just because you can. The new features of vb.net make it easier to develop many types of applications! However, as with all lan

Developers have been asking Microsoft to add more multi-threaded functionality to VB, as well as for vb.net. VB6 has supported the creation of multithreaded EXE, DLL, and OCX. However, using multithreading is probably not a very accurate word. Therefore VB6 only supports cells that run multiple single-threaded threads. A unit is actually a space for code executio
