新添加的列未反映在Crystal Report的数据库字段中。 [英] Newly added columns are not reflecting in Data Base fields of Crystal Report.

问题描述

大家好，



我在datatable中添加了一些列想要更新数据库字段，所以当我点击验证数据库时，标题为ADO的对话框.NET出现并要求提供文件路径，类名，以及从类中使用数据集的选项。 类名预先填充了我的报告的数据源绑定的.Net类的名称。



此时，我'我不知道要为文件路径填写什么。单击完成将弹出一个标题为Crystal Reports ActiveX Designer的对话框，其中显示：登录失败。详细信息：crdb_adoplus：要在设计时访问项目中的类，请先构建项目，然后重试。 （注意：我的项目已经建成了。）





任何人都建议我解决。

Hi all,

I have added some columns in datatable n i want to update Database fields,so when i click "Verify Database" , a dialog titled "ADO.NET" appears and asks for a "File Path," "Class Name," and an option to "Use DataSet from Class." "Class Name" is pre-populated with the name of the .Net class that my report''s data source is tied to.

At this point, I''m not sure what to fill in for "File Path." Clicking "Finish" will bring up a dialog titled "Crystal Reports ActiveX Designer" that reads: "Logon failed. Details: crdb_adoplus: To access classes in your project at design-time, please build your project first, and then try again." (note: My project has already been built).


Any body suggest me the solution.

推荐答案

1。首先检查您的文件是否是最新的并且有新列

2。右键单击datasource - >属性 - > 设置数据源位置

双击路径在文本框中写错了然后它会询问选择文件路径现在再次选择你的文件并刷新数据源
