Create And Run Excel Macro At Runtime in C#

You've been tasked with writing a Windows Form application using the .NET Framework that interacts with Microsoft Excel. If you are new to working with Excel in .NET and are having trouble learning how to format certain cells or cell ranges, then this little tip will come in handy. Rather than scour the internet hoping to find the correct set of constants or method syntax for formatting your spreadsheet, use the built in tools in Excel to write the familiar VBA code for you. Then, you can paste the VBA code generated by Excel into the sample C# code below and run it dynamically at runtime.

Guys...here is my code. it doesn't give any error when i invoke a simple macro from C#. but i don't see any result. all i'm doing in macro is fill some cells Sub firstmacro() Dim i As Integer For i = 10 To 20 For j = 1 To 1 Cells(i, j) = i + 10 Next j Next i End Sub             Excel.Application m_objExcel = new Excel.ApplicationClass();             m_objExcel.Visible = true;                         Excel.Workbook wb = m_objExcel.Workbooks.Open(fName, 0, true, 5, "", "", true,                 Excel.XlPlatform.xlWindows, "", false, false, 0, true);             //m_objExcel.GetType().InvokeMember("firstmacro", BindingFlags.Public, null, null, null);             //m_objExcel.Run("firstmacro");                 //null, null, null, null, null,     null, null, null, null, null,                 //null, null, null, null, null,     null, null, null, null, null,        

Saving Document With Column items applied via excel macro

I have an excel macro that pulls data down from columns within worksheets that will take an excel spreadsheet and save it as a PDF file into seperate folders based off criteria set in the files. Getting the files into the proper directory is not the problem i'm having. When the script executes it saves the documents directly to our sharepoint site, but the custom columns A B C D etc are all blank and some are 'required' items which sets the document as checked out until i go into the list and enter the required data. Is there anyway to make this macro export as PDF and set the required data for me in the sharepoint column so it checks the documents in for me? I'm figuring this is a simple set of meta datatags but I don't know the syntax for them and I didn't find anything like this on the forum anywhere else. ActiveSheet.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _ "http://DirectoryStructureHere/corporate%20BoFi/pdfs/" & NewFileName & ".pdf" _ , Quality:=xlQualityStandard, IncludeDocProperties:=True, IgnorePrintAreas _ :=False, OpenAfterPublish:=False 'Exports the print area as a PDF document named the new filename "Modified: to sharepoint"

Can I import and execute a macro into an Excel file from asp.net?


Is it possible to have an .aspx page open an Excel file, import a macro (saved in a .bas text file), and then run it? I've been able to do this in the past from a MS Access application, but I have no idea where to begin with asp.net. 

If you've done this before code examples would be appreciated, or if you know of any articles on this, links to the articles would be appreciated too.

Read Excel file from Web Application (C#)



I have a web app where user uploads a file.

File is saved in server locally and I want to read some data from it.

Currently my development  server has office 2003.

So do I need office 2007 in order to be able to  read an excel from office 2007 ?

What are other requirements  ?

I tried a test, using

Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook wrkBook; // = new Microsoft.Office.Interop.Excel.Workbook();

wrkBook = excelApp.Workbooks.Open(@"C:\www\excel_files\b.xls", ....);

But When trying to open the file I get the error:

Exception from HRESULT: 0x800A03EC

So I'm wondering what I'm missing.

While Importing Excel 2007 file to Datatable - headerrow problem


Hi there,


I am trying to simply extract an excel data from an uploaded file an put it into a datatable. In this case the excel file has 3 rows but when I fill the datatable I only see row count of 2.

I tried changing HDR:NO; to HDR:YES and vice versa, but no luck. 

What am I doing wrong? (Note: the excel file cannot have a  headerrow)


string connstr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + pFilePath + ";Extended Properties=\"Excel 12.0;IMEX=1;HDR:NO;\"";
            OleDbConnection conn = new OleDbConnection(connstr);
            DataTable dtTables = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, null);
            string strTablename = dtTables.Rows[0]["TABLE_NAME"].ToString();
            string strSQL = "SELECT * FROM [" + strTablename + "]";

            OleDbCommand cmd = new OleDbCommand(strSQL, conn);

            DataTable dt = new DataTable();
            OleDbDataAdapter da = new OleDbDataAdapter(cmd);
            //At this point row count=2 which doesn't make sense
