Visual Studio中的Crystal Reports数据源 [英] Crystal Reports datasource in Visual Studio

问题描述

使用Visual Studio 2005默认安装Crystal Reports。

Using Visual Studio 2005 with default install of Crystal Reports.

当我创建一个报表时，Crystal会询问数据库，并给它我的开发数据库。在应用程序中，我创建一个DataTable并将其传递给报告，然后将其传递给CR查看器。在运行时，报表对象和查看器都不需要查看数据库，因为我已经检索了表。

When I create a report, Crystal asks for the database, and I give it my development db. In the app, I create a DataTable and pass it to the report, which is then handed to the CR Viewer. At runtime, neither the report object, nor the viewer need to see the db since I have already retrieved the table.

当应用程序交给用户时，一切正常精细。他们看不到开发数据库。

When the app is handed to the users, everything works fine. They cannot see the development db.

在生产部门，我在生产站点创建了一个报表，而不是通过指定开发数据库，我给它生产db。回到我自己的办公室，在VS中运行，报表尝试连接到开发数据库，​​并失败。 （它不可见。）

Once, in the production office, I created a report at the production site, and instead of creating the Crystal Report by specifying the development db, I gave it the production db. Back in my own office, running in VS, the report tries to connect to the development db, and fails. (It's not visible.)

所以，这不是一个问题，他们看不到我的开发数据库，​​但它是一个问题，我看不到生产数据库。

So, it's not a problem that they can't see my development database, but it is a problem that I can't see the production database.

问题是：这是否因为在VS中运行与运行安装的应用程序不同而出现？为什么报告尝试连接到数据库？

Questions are: Does this arise because running in VS is different from running the installed app? Why does the report try to connect to the DB anyway? How do I control it?

推荐答案

当你创建报表时，你应该能够做report.SetDataSouce（DataSet）它是您的数据集，其中包含报表使用的表。

When you create the report you should be able to do report.SetDataSouce(DataSet) and pass it your dataset that contains the tables that the report uses.
