error occurs because multiple threads interact with the same data or resources at the same time. This increases the risk of multi-threaded programming! Because it is very difficult to design and debug multi-threaded applications, Microsoft has created the "single-threaded unit" (STA) concept in COM. Visual Basic 6 code is always run in STA, so you only need to c

COBOL, BASIC and FORTRAN have been used for a long time as the main development language. There are many software that use these languages to write and develop the exhilaration. However, after years of development, COBOL and Fortran gradually abandoned, and thanks to the existence of Microsoft, Basic has been enduring. The first thing to say about Visual

threads try to interact with the same data or resources at the same time. When this happens, the problem becomes very complex and difficult to debug. To make things worse, multithreaded code usually seems to work during the initial development period, but in the production process it fails because of unexpected situations where multiple threads interact with the same data or resources at the same time. This increases the risk of multithreaded programming! Because it is very difficult to design

configuration data. A reference to a type is saved in Typetoload. Reflection Classes and Activator classes use their CreateInstance methods to create instances of a type. (CreateInstance is similar to CreateObject in Visual Basic 6.0.) However, the instance must be a type object because the type is to be loaded dynamically. Finally, the newly instantiated object (actually a form) must be converted to
