Reg:使用工具从Vb 6.0迁移到Vb.net 3.5后的性能问题 [英] Reg: Performance issue after migration from Vb 6.0 to Vb.net 3.5 using tool

问题描述

我已经迁移了VB.使用称为ArtinSoft的工具将6.0应用程序转换为vb.net 3.5窗口应用程序.

我既没有重新架构它，也没有优化代码库.
为了使应用程序正常运行，我进行了尽可能少的更改.

现在，我遇到了性能问题.

Vb.net应用程序的性能比VB 6.0应用程序慢得多，因此我们的客户端尚未准备好接受它.
现在，我需要优化代码库，也许我可以将其重新架构到一定级别.
请帮助我使用工具进行此类迁移时需要优化哪些内容?
这是我第一次这样做.

如果有人已经完成了此类迁移项目或类似的活动，请帮助我.


谢谢

Hi,

I have migrated an VB. 6.0 application into vb.net 3.5 window application using an tool called ArtinSoft.

Neither have I re-architected it nor optimized the codebase.
I have made as least as possible changes just to make the application run properly.

Now I am facing the performance issues.

Performance of the Vb.net application is much slower from VB 6.0 application so our client is not ready to accept it.
Now I need to optimize the codebase and may be I can re-architect it up to an certain level.
Please help me on what are the things I need to optimize when we do this type of migration using an tool?
This is first time I did so.

Please help me if someone has already done this type of migration project or similar activity.


Thanks

推荐答案

我没有像您那样迁移过一个应用程序(总是重写了该应用程序)，但这是我要做的/考虑的事情:

-重写非常慢的代码

-使用.NET框架.编写可替换外部组件或包装器的代码. (类似于SerialPort，而不是某些rs232类).

-使用BackGroundWorker进行耗时的操作.

I haven''t migrated an application like you did (always rewrote the application), but this is what I would do / consider:

- rewrite code that is really slow

- use .NET framework. Write code that can replace external components or wrappers. (Like SerialPort instead of some rs232 class).

- use BackGroundWorker for time consuming actions.

- use a splash screen at startup and other visual effects like hourglass, progressbar, clock or anything that shows the user that the application is busy.

- place the assembly in the Global Assembly Cache (GAC). I wouldn''t recommend it, but it is something to consider.

- how are you connecting to the database?

- and like cuteband advised: use stored procedures

I hope this gives you some ideas and options.
