VB 6 is an old application development framework that targets the COM infrastructure which in turn depends upon the useable components of the Windows framework.
VB 6 is considered extremely simple since it doesn’t depend on outside components since all the functions and features that are required by the application are shipped in the form of runtime libraries with VB 6 application code. VB 6 code can either be compiled to interpreted P-code or the native runtime code.
On the other hand, Microsoft VB.NET is the new generation language that targets .NET runtime and is part of Microsoft’s .NET Framework. VB .NET borrows usable components from the .NET framework whereas the execution of the VB.NET code is the responsibility of the .NET runtime.
Since VB .NET code is first compiled into Microsoft intermediate language code which is common for all Microsoft languages such as C#, J#, etc. This makes VB.NET eligible for the back-end programming language of ASP.NET applications as well. The following are some of the basic differences between Visual Basic and Visual Studio.
If we look at the nitty-gritty of the migration of VB 6, we realize that at the fundamental level VB 6 migration can be summarised into two broad points. These are as follows:
A whopping 80% of the code migration is premised on regulating the code queries and testing them for future usability. This is mere because multiple variants of the VB 6 have been deprecated. Along with this, VB.Net has a whole set of structures, which is bolstered on the network of .Net.
The users should be aware that the migration of the query is being done either by the developmental team or between the client and the Microsoft services. Services and advisory is a vital aspect of migration and is feasible mostly after the migration process, though the involvement of hands-on tasks is not involved initially.
VB.Net also is inclusive of something known as a “Conversion Wizard” that has the role of converting a subcategory of the VB 6 code to the VB.Net code.
The majority of the professionals in this field advise the programmers to accomplish a series of manual groundwork so that it proves helpful to adjust any differences that are found in the language arena.
This step is basically prior to the actual usage of the conversion tool. Parallel to popular belief, it is considered better when research is done frequently and thoroughly, implying the minimizing number of errors that will need to be fixed in the output post-conversion.
The agenda that is involved in the process of preparation is proven to be very helpful in clarifying some very vital alterations between VB.Net and VB 6. The types of data and information from VB 6 needs to be adjusted and fit into for VB.Net, especially the variant of the data that accepts data input in any form whatsoever.
All in all, this article was all about vb 6 vs vb net. Some might say that this kind of structure makes the process of coding look easy since it does not need a stern classification of listing out the variables. But in all fair actuality, this is not feasible in VB.Net where the variant is replaced by the object.
In between all of these formations, searching for a code of VB 6 for utilities of replacing other stalwartly noted variables and objects is a step that should be carried out prior to using the Conversion Wizard.
The following are some of the blogs and articles that explain the process of converting VB 6 programs to VB.NET.
