推荐答案

据我了解您的问题，我可以说您必须为此创建一个通用类，该类将具有水晶报表所需的一切. .

例如...该类应包括以下成员...您可以有更多，但这些是基本成员...

as far as i understood your question i can say that you must create a general class for that which will have everything a crystal report needs...

for example... that class should include the following members... you can have more but these are the basic ones...

CrystalReport (CRPT)
CrystalReportViewer (CRV)
Table
Query

另一方面，您必须具有可以接受以下参数的功能...

on the other hand you must have function which will accept the following parameters...

ShowReport(ByVal TableName As String, ByVal CRV As Object, ByVal CRPT As Object, ByVal Query As String, Optional ByVal ParameterValue As Object = Nothing)

其余的一切由您决定...

and the rest is upto you...
