使用Sharepoint定时运行Excel中宏程序

需求:
因为Excel中数据量很大,其中包含了几个宏程序从其他数据源读取数据,运行一次宏需要比较长的时间,为了不影响使用,要求每天半夜运行一次Excel中的宏(无参数),Excel存放在共盘上。

解决方案:
Sharepoint上写了一个Timejob,Timejob每天去运行宏。
写Timejob参考http://www.cnblogs.com/batter152/p/4705316.html

在运行时会碰到的问题
ERROR – RETRIEVING THE COM CLASS FACTORY FOR COMPONENT WITH CLSID {00020812-0000-0000-C000-000000000046} FAILED DUE TO THE FOLLOWING ERROR: 80070005 ACCESS IS DENIED. (EXCEPTION FROM HRESULT: 0X80070005 (E_ACCESSDENIED)).
或者报错没有权限,或者报错说
Microsoft Excel cannot access the filee 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.

通过做下面两个步骤就可以解决:

1.创建桌面快捷方式
需要手动创建文件夹,把Excel运行快捷方式放到这个文件夹下面
64位系统: C:\Windows\SysWOW64\config\systemprofile\Desktop
32为系统: C:\Windows\System32\config\systemprofile\Desktop

2.修改运用程序的权限
64位系统运行dcomcnfg
32位系统运行mmc -32,然后添加Component services
展开Services –> Computers –> My Computer –> DCOM Config如下图,这个账号是IIS80端口Application Pool的账号

找到Microsoft Excel Application CLSID {00020812-0000-0000-C000-000000000046}
点Security Tab修改,点Identity Tab 修改分别如下

也可以把默认修改一下,右击My Computer

附上C#运行宏程序的代码如下

引用

using Excel = Microsoft.Office.Interop.Excel;
//using Microsoft.Office.Core;

DLL: Microsoft.Office.Interop.Excel

并且设置dll属性Embed Interop Types为False,不然也会报错

1.使用方法

protected void Page_Load(object sender, EventArgs e)
        {
            try
            {
                // 返回对象
                object objRtn = new object();
                // 获得一个ExcelMacroHelper对象
                // 执行指定Excel中的宏,执行时显示Excel
                SPSecurity.RunWithElevatedPrivileges(delegate()
                {
                    //RunMoc(@"C:\Library\test.xlsm", "ThisWorkbook.getTime", null, out objRtn, false);
                    string source = @"\\xxxxx\Test\TEST.xlsm";
                    string destination = @"C:\Library\TEST.xlsm";

                    //File.Copy(destination,source,true);

                    RunMoc(source, "TEST.xlsm!TEST.test", null, out objRtn, false);

                    
                });
            }
            catch (System.Exception ex)
            {
                lb_error.Text = ex.Message;
            }
        }

2.运行方法

3.VBA代码,模块名字是TEST

Sub test()
With ThisWorkbook.Sheets("sheet1")
    n = .Cells(11111, 2).End(xlUp).Row + 1
        .Cells(n, 2) = Time
        .Cells(n, 3) = Date
    End With
End Sub
