I just found that Report Control in C#.NET takes 50 times slower than it in VB6, take a look at these two demos:
(1)Open C#.NET\ReportSample\ReportSample.sln project, then edit this code: for(int k=0 ; k<1000;k++) AddRows(); It takes about 58.3 seconds to add 18013 rows. (2)Open VB\ReportSample\ReportSample.vbp project, add the following lines: (a) cstrCJlink = "https://forum.codejock.com" Dim j As Long ' < ---------- add For j = 1 To 1000 ' < ---------- add 'Start Adding Records with the AddRecord helper subroutine 'Look at the AddRecord subroutine for a more detailed explanation (b) Next '<----------- add 'Vertical grid lines will be drawn as small dots 'wndReportControl.PaintManager.VerticalGridStyle = xtpGridSolid It takes only 1.1 seconds to add 18013 rows. How to impove the performance in C#.NET? Any advice would be greatly appreciated!! Thank you! |
