before learning the VB6.0, with their first VB6.0 to write the system, although the quality of their completion is not flattering, but still small with a sense of accomplishment. Now has just completed vb.net study, the video is not very detailed explanation, but probably related to some knowledge, but "with apprenticeship door" they certainly still have a lot of similarities, VB. NET is nothing more than on the basis of VB to do the extension and development. Below one by one
"The draught does not forget the drilling person"--to VB6.0
Vb. NET introduces some related trivial knowledge, more is the understanding and familiarity with the vb.net environment, in a small example introduced familiar statements, controls and structures, which particularly emphasized the prevention and treatment of the error of the technology: by throwing the way is triggered by the catch mode is captured, Feedback to the server by means of information, connection with database, use of powerful interface function ...
Here are some of your own map guides:
"Superseding"--thank you, I will do better
VB cancels the tedious code writing work, thus makes the programming method under the Windows brand-fresh, but its function still has the certain limitation And then developed into VB6.0, the programming language of his own system, which provided a new way to access the database, using integrated ADO (ActiveX Data Objects), which enabled access to the database. Today, it has developed into a vb.net, which is a more perfect language.
Here's how they compare:
VB6.0 and VB.net |
Same point |
Different points |
Basic events
|
You can set the positioning order by simply selecting the control. |
By setting the AutoScroll property, you can determine whether the form appears in reel |
Basic methods
|
Control has the Anchor property |
Units of measure are using pixels instead of twips |
Basic properties |
The Accept and Cancel buttons can be set directly in the properties of the form |
As a complete process development process, deployment is also a very important part of the deployment can be divided into original deployment and remote deployment (that is, we often say offsite release), good deployment can make the software function and performance better, especially in the remote deployment, therefore, should pay attention to the work of deployment. There are two types of deployment, namely "xcopy" Deployment and "0 deployments", XCOPY deployment refers to the Exe,dlls and related documents are all copied to the same folder, while the 0 department refers to the exe a URL, the user directly through IE browsing the URL, followed by. NET sets AppBase to the virtual directory on the Web server, and then. NET download EXE and DLLs from AppBase.
The above is their own summary of the knowledge in the vb.net, of course, there are a lot of omissions and shortcomings, but also ask you to advise!
