is the explicit implementation of C # or VB Implements statements are such a principle. Other words. NET provides the function of exchanging name to implement interface member, but only VB has given this freedom to the user, but other languages still adopt the classic grammar. Vb. How

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 begin

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. Vb5 introduces "interface inheritance" so that VB developers can expand existing objects to a cert

After a long period of development, VB. NET has become very familiar to many users. Here I will share my personal understanding and discuss it with you. Here we will give you a question about packaging VB. NET.As an upgraded version of VB6, VB.

Here is a summary of the VB. NET new method. Let's take a look. VB. NETThe new method is like sub.Main, class_initialize is called before other VB6 classes run code. In addition, it is called before error processing, so debugging becomes very difficult, and errorsThe error is displayed on the client to instantiate the

Program You no longer need to use the WIN32 application programming interface or VB Shell function to start the external application. Because you can use. NET Framework to further simplify the code by doing this operation with the System.Diagnostics.Process class. Although. NET makes a lot of things more complicated, but it's not the start of an external applicat

) would use the wrong variables. Does that API accept a 16-bit integer or 32-bit? Oh, my God! I want Microsoft to reconsider this decision and use the new variant types, such as Int32 and Long64. Either migrate to VB. NET porting tool is so good that it does not change the memory of the developer. Why would you force us to learn the normal data type again? Final

String connection is an operation that is frequently used during development. The purpose of this comparison is to look at the improvement of. Net in string connection and the efficiency of full compilation? Test using three development tools: VB6, VB. net2003 (because C # is the same as VB.

then set the Form area to the custom Region. In this way, we can get the following circular Form to be more beautiful, we can set the BorderStyle of Form to None, and then draw a TitileBar by ourselves to make it a lively application. How to achieve the above effect in VB. Net:VB. NET is a cross-platform language that makes better use of the object-oriented mechanism. Its object-oriented capability extends

Notes | concepts | Grammar begins with basic concepts and grammar Learning a language, especially now is the development of visualization, but I suggest that it is not urgent to drag a few controls first, but the sense of the first to understand the concept of the language, grammar and norms. Vb. NET is very close to the previous VB6, but since the vb.net is

Vb. NET Create irregular form Montaque (original) In general, the form of an application is a regular, rectangular form. Sometimes for a particular purpose, we want to change the shape of the application form, such as being a MP3 player, a small clock, and so on, which requires "customizing" our Application. In addition, specially shaped forms can sometimes attract the attention of users, making them pay s

To elaborate on VB. NET (Next) (Author: Green Apple Studio compiled March 07, 2001 14:47) Forms and new IDE faces Visual Basic.NET is a great object-oriented feature, but it was not noticed the first time you started vb.net. Perhaps the first thing you notice is its IDE. The IDE may seem familiar to you, the team that built the Vs.net IDE was working on developing the IDE for

Learning VB. NET is not as difficult as you think. Teacher Mi said that all languages are figured out. If you master one of them, you will find similar things when learning other languages. Learning VB. NET is like this, because it is very similar to C. We learned VB6 in th

Vb. NET Audio playback Montaque (original) After the VB6 upgrade to. NET, some people are not clear about the sound processing, such as when the program is wrong, customizing a sound playback, or the program's background music, including game music, and so on. Here are some simple and achievable solutions in vb.net:

the upper bound of the BARR subscript, which can have 6 elements Dim Larr () as Long = New Long (3) {100, 200, 300, 400} Dim CARR () as String = New String () {"A", "B", "C"} Dim Darr ( -1) as Double End Class More features about arrays are described in detail in the later introduction of arrays. Compound assignment Now vb.net is starting to support compound assignment statements. Unlike a fully expanded expression, a variable on the left side of a compound assignment statement is

an array of 10 integers, indexed from 0 to 9. Based on the changes above, Option Base 0|1 has been removed from the Visual Basic.NET deleted. When your code is upgraded to Visual Basic.NET, an array with a lower bound of 0 will not Change. If the lower bound of the array is not 0, the array is upgraded to a compatible class, as follows: Dim A (1 to ten) as Integer Change to: Dim A as Object = New VB6. Array (GetType (short), 1,10) Compatible arr
