解决方案

Suresh，


看，没有单一的最佳选项。我可以举一些关于

的例子，哪种方式最适合应用程序的性质：


a）选项桌面应用程序的对话框。通常设置是存储在注册表或配置文件中的
。请参阅

Microsoft.Win32.Registry类和System.Configuration命名空间以获取更多详细信息和示例。


b）A偏好 Web应用程序的Web页面。 Web应用程序最多

经常与某种数据库一起使用，并且通常将所有信息存储在数据库中。有关更多信息和示例，请参阅System.Data命名空间文档

。


c）桌面CRM应用程序中的客户详细信息。这种复杂的应用程序

通常也依赖于某种数据库或结构化存储。


P.S.事实上，你问的问题是宽带。我建议你

面临一个特定问题，如果你想描述你想要实现的东西，我认为社区可以提出更详细的建议。 />

Dmitriy，


感谢您的回复。


好​​吧，这就是我想要的。我的应用程序是使用VB.NET开发的
设计是这样的。


A.表单1旨在让用户输入部件号。表单

1有两个按钮Okay和取消如果用户

点击Okay，则会验证文本文件并读取部件号的

详细信息，部件号将作为
$传递b $ b a参数表格2.


B.表格2显示部分编号的所有其他详细信息，例如绘图日期，批准日期，描述等。这些

值放在表格2上。三个按钮可用于

表格2，保存 "取消] " EXIT"允许用户更改

部件号以外的部件号的任何其他详细信息。用户更改任何详细信息保存并退出

应用程序。


要求是，如果用户返回

应用程序第二次。我应该能够在表单1中显示他/她正在处理的部分号码。


如何保留此值并显示它？


希望我已经解释过了。

Dmitriy，


感谢您的回复。我的选择也是一个文本文件。只是

很想知道如何将值编码到

Suresh，
现在我明白了。我认为注册表或简单的文本文件
是最好的选择。当用户关闭表单1时，请阅读文本框
值并将其保存到具有相应Framework
类的注册表/文件中。在Form 1st-up上，检查您之前是否存储了价值
并预填充文本框。

How do you retain the last value the user keyed in a text
box? I should be able to show the values when the user
runs the executable for the second time.

Appreciate help.
Suresh

解决方案

Suresh,

See, there is no single "best" option. I could just give some examples on
which way fits best the nature of the application:

a) An "Options" dialog box of a desktop application. Usually settings are
stored in the registry or in a configuration file. Please refer to the
Microsoft.Win32.Registry class and to the System.Configuration namespace for
more detailed information and examples.

b) A "Preferences" web page of a Web application. Web applications most
often work with some kind of database and usually store all information
within the database. Please refer to the System.Data namespace documentation
for more info and examples.

c) Customer details in a desktop CRM application. Such complex applications
also usually rely on some kind of database or structured storage.

P.S. In fact, the question you are asking is too "broadband". I suggest you
are facing a particular problem, and if you would describe things you want
to achieve, I think the community could came up with more detailed advice.

Dmitriy,

What would be the best option to do this? Do you have a
sample coding on this?

Thanks in advance,

Suresh

Dmitriy,

Thanks for your reply.

All right, here''s what I want. My application is being
developed using VB.NET The design is this.

A. Form 1 designed for user to enter the part number. Form
1 has two buttons "Okay" and "Cancel" If the user
clicks "Okay", a textfile is validated and read for the
details of the partnumber,and the part number is passed as
aparameter to form 2.

B. Form 2 shows all other details of the partnumber such
as drawing date, approved date, description etc. These
values are placed on Form 2. Three button are availableon
form 2, "SAVE" "CANCEL" "EXIT" The user is allowed to
change any other details of the part number other than the
part number. User changes any details saves and exit the
application.

The requirement is that, if the user comes back the
application the second time around. I should be able to
show the partnumber he/she was working on in the Form 1.

How do I retain this value and show it?

Hope I have explained.

Suresh

Dmitriy,

Thanks for your reply. My choice was a text file too. Just
curious to know how do you code the values to the
registry? Do you have a sample. ''Cos I have not written
any codes before to write to the registry. Also won''t the
registry cause a security issue when deploying the project?

Suresh

Suresh,

Now I see. I think registry or a simple text file would be the best choicehere. When the user closes the Form 1, read the text box value and save itto the registry/file with the appropriate Framework classes. And upon Form 1start-up, check whether you have previously stored value and pre-populatethe text box.
