VB程序打印水晶报表的方法

VB程序打印水晶报表的方法.

环境: MS SQL SERVER 2000 / VB6 / CRYSTAL REPORT8.5

步骤

1: 建立ODBC连接

2: 创建一个为Crystal Report报表文件

3: 加载Microsoft ActiveX Data Objects Library 至项目的References 中

4. 创建VB 设计(Designer) , 通过open existing file的方式把Crystal Report报表文件加载进来. 如果报表条件从画面输入需要写一些简单程序, 举例

Dim adoRs As ADODB.Recordset

Private Sub Report_Initialize()

SQL$ = "select * from view_XXXX where XXXX "

‘根据画面,重新获得where条件’

Set adoRs = CreateObject("adodb.recordset")

adoRs.Open SQL$, "Provider=MSDASQL.1;Persist Security Info=False;Data Source=odbc_sales", adOpenKeyset, adLockBatchOptimistic

Database.SetDataSource adoRs

End Sub

Private Sub Report_Terminate()

Set adoRs = Nothing

End Sub

5: 创建VB画面(Form) ,加入Crystal Report Viewer控件

一些简单程序, 举例

Dim RptReportName As Rpt_ReportName ‘RptReportName is name of designer Private Sub Form_Load()

CRViewer1.ReportSource = RptReportName

CRViewer1.ViewReport

End Sub
