在 Crystal Report for Visual Studio 中加載數據庫信息失敗

Question

我在使用 VS2013 的 Crystal Reports 時遇到問題。 我有一個在 VS2010 中使用 CR 開發的 Windows 應用程序。

當我嘗試在 VS 2013 中運行它時，出現以下異常：

Failed to load database information.
Error in File BillReport {E3FDAF36-9149-4F03-BCB6-EE66639AFFFB}.rpt:

以下是我從由 OLEDB 連接填充的 XML 數據集加載水晶報告的代碼

string sqlstr = "";
sqlstr = "select * from billMaster where billid =  " + billId + " and merchantName = '" + merchantName + "' ";
// DataSet ds = m1.selectData(sqlstr);

cmd = new OleDbCommand(sqlstr, m1.ccon);
if (m1.ccon.State == ConnectionState.Closed) {
    m1.ccon.Open();
}
OleDbDataAdapter da = new OleDbDataAdapter(sqlstr, m1.ccon);

BillPrint bp = new BillPrint();

// dr = cmd.ExecuteReader();
da.Fill(bp.billMaster);
sqlstr = "select srNo from billInfo where billId=" + billId + " order by srNo";
DataSet dsTemp = m1.selectData(sqlstr);
sqlstr = "select (srNo+1-" + dsTemp.Tables[0].Rows[0].ItemArray[0].ToString() + ") as srNo,billId,itemType,itemName,length,width,thickness,squareMeter,billRate,Qty,subTotal from billInfo where billId=" + billId;
OleDbDataAdapter da1 = new OleDbDataAdapter(sqlstr, m1.ccon);
// dr = cmd.ExecuteReader();
da1.Fill(bp.billInfo);

string path = "";
path = Application.StartupPath + "\\reports\\BillReport.rpt";

/* if (RateVisible == 1)
{
    path = Application.StartupPath + "\\reports\\BillReport.rpt";
}
else if (RateVisible == 2)
{
    path = Application.StartupPath + "\\reports\\BillReportWithoutRate.rpt";
}*/
//  MessageBox.Show(path);

ReportDocument rd = new ReportDocument();
rd.Load(path);
rd.SetDataSource(bp);
crv.ReportSource = rd;
crv.RefreshReport();

Answer 1

在 app.config 中的<configuration>元素下的代碼下方添加<startup>代碼

<startup useLegacyV2RuntimeActivationPolicy="true"></startup>

Answer 2

我的水晶報表安裝目錄中缺少crdb_adoplus.dll 。

C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win64_x64

我已經以管理員權限重新安裝了 Crystal Report 運行時，然后安裝了crdb_adoplus.dll 。 報告正在完美打開。

在我的情況下，不需要更改 Web.config/App.config。

此問題可能出現在舊版本的crruntimes中。 如果您升級您的版本，您必須為您的處理器架構（x86 或 x64）安裝最新的crruntime ，然后您需要查看它是否有效。 如果不是，我發現此文件夾中缺少許多文件： "C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0"

它必須看起來像這樣。

如果您的項目中有水晶報表的 13.0400 版本 DLL，這將是您問題的解決方案。

Answer 4

我在使用 Crystal Reports 時遇到了錯誤“無法加載數據庫信息”。

報告可以在我的機器上運行（作為開發人員並安裝了 Visual Studio），但不能在客戶端機器上運行並顯示列出的錯誤。

我通過執行以下操作修復了錯誤：

1. 我使用平台 x86 構建了該項目。
2. 盡管客戶端機器的 Windows 平台是 x64，但我在客戶端機器上安裝了 Crystal Runtime 64 位和 32 位。
3. 確保每次安裝后重新啟動機器。

做了這些步驟，問題就解決了。 希望它可以幫助你。
