如何将数据源字符串传递给Crystal Reports [英] How to pass a datasource string to Crystal Reports

问题描述

亲爱的朋友.

我正在VB.Net中的一个项目上.我需要在项目中添加一些报告.但是在VB.Net中，我找不到任何将字符串(包含连接信息和数据源，数据库信息)传递给Crystal Reports的方法.

因此，我正在使用从文本文件(DB.txt)中拾取的字符串(StrInfo).之所以这样做，是因为我希望如果我需要更改数据库文件的路径，只需更改文本文件(DB.txt)，然后字符串(StrInfo)就会从文本文件获取路径.因此，我想将字符串传递给Crystal报表.

请以某种方式告诉我.

Dear Friends.

I am working on a project in VB.Net. I need to add some reports in my project. But here in VB.Net, I did not found any way to pass a string (which contains Connection info and Data Source, Database info) to Crystal Reports.

So, I am using a string (StrInfo) which is picked up from a text File (DB.txt). I have done this because I want that If I need to change the Path of My Database File, I will just change the Text File (DB.txt) and The string (StrInfo) will get the path from text file. So Therefore, I want to pass the string to crystal reports.

Please tell me some way.
