Q:excel的第1，2行有数据，第3，4行没数据，第5行有数据，第5行数据显示不出来。

A:sheet.getPhysicalNumberOfRows()获取有效的行数，多谢热心网友的指正，改进后代码如下：

C# (Microsoft.Office.Interop.Excel)，将数据另存为 Excel 2003 文件(xls)

如何解决C# (Microsoft.Office.Interop.Excel)，将数据另存为 Excel 2003 文件(xls)

我能够创建将数据保存到扩展名为“xlsx”的excel文件的代码。 但是，我需要找到一种方法将数据导出为扩展名为“xls”的旧 Excel 文件格式。

有什么简单的方法可以实现吗？

这是我的代码：

wb.SaveAs(fileName,Excel.XlFileFormat.xlOpenXMLWorkbook,Type.Missing,false,Excel.XlSaveAsAccessMode.xlNoChange,Excel.XlSaveConflictResolution.xlUserResolution,true,Type.Missing);

感谢您阅读本文。

解决方法

wb.SaveAs(fileName,Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal,Type.Missing,Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive,Type.Missing);

Delphi 2007 x Windows 10 - 打开项目时出错 (Delphi 2007 x Windows 10 - Error on opening project)

问题：

Just updated from Windows 8.1 to Windows 10 and now when I try to open any project on Delphi 2007, I get his error :

Unable to load project xxxxx The imported project "c:\Windows\Microsft.NET...\Borland.Delphi.Targets" was not found. Confirm that the path declaration is correct, and that file exists on disk

查找需拷贝的文件路径：

在 C:\Windows.old 目录下搜索 Borland.Common.Targets 就能找到该文件所在路径。

解决方案：

You need to copy some files in your old Windows folder to the new one. After that projects open again.

The needed files are these :

c:\windows\Microsoft.NET\Framework\v2.0.50727\Borland.Common.Targets
c:\windows\Microsoft.NET\Framework\v2.0.50727\Borland.Cpp.Targets
c:\windows\Microsoft.NET\Framework\v2.0.50727\Borland.Delphi.Targets
c:\windows\Microsoft.NET\Framework\v2.0.50727\Borland.Group.Targets

Excel 2019 与 Excel 2007：数据验证？

如何解决Excel 2019 与 Excel 2007：数据验证？

Excel 版本有问题。

使用 Excel 2019，我create a file 进行了数据验证。 col1 必须在这些值中 (=DATA!A2:A6)。 因此，我选择整个 A 列并选择 data validation 并指定 =DATA!A2:A6 作为源。 但是当我转到 col1 的第一行时，第一个值没有出现，当我检查单元格的数据验证时，我发现它已更改为该单元格 becoming =DATA!A3:A7>

这种行为在 Excel 2007 上不会发生，而且我的原始文件是用 Excel 2007 创建的。

有什么帮助吗？

谢谢
