本文介绍了以编程方式在Crystal报表中移动Line对象时发生错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

strNAme = ds.Tables("report").Rows(i).Item("LabelName")

 Dim Line As LineObject = DirectCast(rpt.ReportDefinition.ReportObjects(strNAme), LineObject)
   Line.Left = ds.Tables("report").Rows(i).Item("Align_Left")' ERROR IS HERE
 Line.Top = ds.Tables("report").Rows(i).Item("Align_Top")
  Line.Right = ds.Tables("report").Rows(i).Item("Align_Right")
   Line.Bottom = ds.Tables("report").Rows(i).Item("Align_Bottom")

我在
上出错Line.Left

捕获了System.Runtime.InteropServices.COMException
ErrorCode = -2147213284
Message =线对象的坐标无效.仅支持垂直或水平线."

i am getting error on
Line.Left

System.Runtime.InteropServices.COMException was caught
ErrorCode=-2147213284
Message="The line object''s coordinates are not valid. Only vertical or horizontal lines are supported."

推荐答案

if (Hline)
{
    //Hline. set left and right = left you want
    lineObj.Left = Twip.PixelToTwipX(this.X1);
    lineObj.Right = lineObj.Left;
    //set top and bottom = top you want
    lineObj.Top = Twip.PixelToTwipY(this.Y1);
    lineObj.Bottom = lineObj.Top;
    //set right
    lineObj.Right = Twip.PixelToTwipX(this.X2);
}
else
{
    //My language
    //đường dọc. cho top và bottom bằng top mong muốn
    lineObj.Top = Twip.PixelToTwipY(this.Y1);
    lineObj.Bottom = lineObj.Top;
    //Đổi left = right = left mong muốn
    lineObj.Left = Twip.PixelToTwipX(this.X1);
    lineObj.Right = lineObj.Left;
    //Đổi bottom
    lineObj.Bottom = Twip.PixelToTwipX(this.Y2);
}
