크리스탈 보고서가 개체 참조를 개체의 인스턴스로 설정하지 않음으로 보냅니다.

Question

VS 및 WFP 용 Crystal Report를 사용하여 창에서 보고서를 봅니다. 시작시 는이 오류에 직면했다 :

System.ArgumentNullException -- System.ArgumentNullException: Value cannot be null. 
Parameter name: window 

가 그럼 난이 solution을 다음 그것을 해결했습니다.

System.NullReferenceException -- System.NullReferenceException: Object reference not set to an instance of an object.

• 내 보고서는 어떤 분야가 없습니다, 물론 더 매개 변수 I가 없습니다 :

  이제 또 다른 모호한 메시지는 심지어 this 다음 그것에 대한 해결책을 찾을 수 없다는 것을 나타납니다 보내다.

• 모든 텍스트가 페이지 크기에 포함되어 있습니다.

인쇄에 보고서를 설정 뒤에 내 코드 :

public void PrintReport() 
{ 
    string reportPath = System.IO.Path.Combine(new System.IO.DirectoryInfo("reports").FullName, "taklif-tansik.rpt"); 
    //MessageBox.Show(reportPath); 
    try 
    { 
     cryRpt = new ReportDocument(); 
     cryRpt.Load(reportPath); 
     if (cryRpt.IsLoaded) 
     { 
      ReportPrintWindow = new ReportWindow(); 
      //cryRpt.Refresh(); 
      ReportPrintWindow.RptViewer.ViewerCore.ReportSource = cryRpt; 
      ReportPrintWindow.Show(); 
     } 
    } 
    catch (Exception exEngineException) 
    { 
     MessageBox.Show("exEngineException " + exEngineException.ToString()); 
    } 
}

Answer 1

Crystal Report의 불일치 런타임 dll 파일을 두 번째

Memory full. 
Not enough memory for operation. 

: 개발 시스템과 클라이언트 시스템이 문제가 발생

System.NullReferenceException -- System.NullReferenceException: Object reference not set to an instance of an object. 

솔루션 :

는 클라이언트 시스템에서 개발 시스템에서 사용되는 동일한 버전을 설치합니다. 내 설치된 버전은 이고 클라이언트 컴퓨터 13.0.12은 13.0.12을 제거하고 클라이언트 컴퓨터에 13.0.19을 설치하여 문제를 해결했습니다.

Visual Studio 버전과 관련된 Microsoft Visual C++ Redistributable을 설치하는 것이 좋습니다.
