1933258 - CR for .NET SaveAs method always appends .rpt to the report

When opening a report with an extension other than rpt when using the SaveAs method it appends .rpt to the report.

Crystal Reports Developer for Visual Studio 2010 +

rpt.load(@"c:\reports\myreport.don");

rptClientDoc = rpt.ReportClientDocument;

private void btnSaveReportAs_Click(object sender, System.EventArgs e)
{
    saveFileDialog.Filter = "Crystal Reports (*.rpt)|*.rpt";
    if (DialogResult.OK == saveFileDialog.ShowDialog())
    {

        object saveFolder = System.IO.Path.GetDirectoryName(saveFileDialog.FileName);
        string saveFileName = System.IO.Path.GetFileName(saveFileDialog.FileName);

        if (!IsRpt)
        {
            rptClientDoc.SaveAs(saveFileName, ref saveFolder,
                (int)CdReportClientDocumentSaveAsOptionsEnum.cdReportClientDocumentSaveAsOverwriteExisting);
        }
        else
        {
            try
            {
                rpt.SaveAs(saveFileName, true);
            }
            catch (Exception ex)
            {
                btnSQLStatement.Text = "ERROR: " + ex.Message;
            }
        }
    }
}

Saves the report as myreport.don.rpt

Because Current versions of Windows allow multiple periods in the file name CR for .NET simply appends RPT to the file name.

Previously this would have replaced the extension.

Work around is to rename the file outside of CR .NET API's
