在vb.net和sql server数据库中使用crystal report进行报告 [英] make a report with crystal report in vb.net and sql server database

问题描述

亲爱的，亲爱的所有最好的程序员，



这是我的第一篇文章或者也许是一个问题，但希望尽管我是vb .net的初学者和新手你会喜欢帮助解决我的问题。



i当我使用sql server数据库在vb.net中使用水晶报表制作报表应用程序时遇到一些问题。我做一个简单的应用程序，包括一个按钮显示报告和一个水晶报告viwer。我把代码放到按钮show report：

  Imports  CrystalDecisions.CrystalReports.Engine 
 
 公开 类 Form1 
 
 私有  Sub  Button1_Click（发件人作为 对象，e  As  EventArgs）句柄 Button1.Click 
  Dim  cryRpt  As  新 ReportDocument 
 cryRpt .Load（  Data Source =（localdb）\Projects; Initial Catalog = crystaldb; Integrated Security = True）
 CrystalReportViewer1.ReportSource = cryRpt 
 CrystalReportViewer1.Refresh（）
 
 结束  Sub  
 
 结束 班级 

当我运行该程序时，实际上没有问题，但为什么我必须首先进行操作登录。动作登录包含一些字段，它们是服务器名称，数据库，id和密码。服务器名称自动填充，数据库字段为空，但我无法填写。对于空的ID和密码，我必须能够填写它。



的id和pasword字段，我不知道我是什么东西必须填写该领域。希望任何人都能清楚地理解我的问题和问题，并尽快帮助我。





谢谢和最诚挚的问候，
