Excel 2007 automation on top of a Windows Server 2008 x64
今天在一个客户这边出来一个windows service的问题。这个service需要启动excel程序,并且对一些excel文件做一些操作。
环境是:windows server 2008 x64+Excel 2007
总是报告错误:(类似下面这样)
Service cannot be started. System.Runtime.InteropServices.COMException (0x800A03EC): Microsoft Office Excel cannot access the file 'c:\temp\test.xls'. There are several possible reasons:
• The file name or path does not exist.
• The file is being used by another program.
• The workbook you are trying to save has the same name as a currently open workbook.
代码怎么看都是可以的,反复调试了service,问题最后解决了,大致有如下几点
第一步:在服务器添加有关的一个目录
This solution is ...
・Windows 2008 Server x64
Please make this folder.
C:\Windows\SysWOW64\config\systemprofile\Desktop
・Windows 2008 Server x86
Please make this folder.
C:\Windows\System32\config\systemprofile\Desktop
...instead of dcomcnfg.exe.
This operation took away office automation problems in my system.
A Desktop folder seems to be necessary in the systemprofile folder to open file by Excel.
It disappears from Windows2008, Windows2003 had the folder,
and I think it cause this error.
I think it is safer than "registry hack".
If you try this solution, please let me know results.
第二步:设置服务与桌面交互
第三步:关闭服务器的UAC(这一步至关重要,调试了一个下午,就是因为这个问题卡住)
