Crystal Reportview对象未正确处置 [英] Crystal Reportviewer Object Not Disposing properly

问题描述

Crystal Report查看器对象未正确处置



大家好我有一个问题我有一个水晶报告并使用vb.net。



我写的代码如下所示

 对于 i = 0    15  
 
 尝试 
 
  Dim  vRep 作为 新 CrystalDecisions.CrystalReports.Engine.ReportDocument 
 vrep.export（）
 
 
 < span class =code-keyword> Catch  
 
 
 最后 
 
 vrep .close（）
 vrep.dispose（）
 
  end  试用 
 
  NEXT  

vre时出现问题p.export引发异常然后在下一个循环步骤中我希望能够处理vrep.close（）

和vrep.dispose（）

解决方案

< blockquote>不要那么说。将那些（昏暗，关闭，处置）放在循环之外（导出也应该在外面但不确定）。解决了。

并查看此提示/技巧

Crystal Report viewer Object Not Disposing properly

Hello guys i have one problem i have one crystal report and using vb.net.

I write code where as below

For i=0 to 15 

Try

    Dim vRep As New CrystalDecisions.CrystalReports.Engine.ReportDocument
    vrep.export()


Catch


Finally 

      vrep.close()
      vrep.dispose()

end try

NEXT

Problem occurs when vrep.export raise exception then in next loop step i want be able to dispose vrep.close()
and vrep.dispose()

解决方案

Don't put that way. Put those(Dim, close, dispose) outside of loop(export also should be outside but not sure). Solved.
