Create Excel file dynamically in SSIS package and fill it by resultset data returned by Stored proce


Hello Every One,

I have a scenario in which i am executing a Stored Procedure which returned a result set.

I want to create a Excel file [name_date_time] dynamically, and fill result set data into Excel file. And then finally sent Excel file to Specific user[Email ID].

Point is that the excel file should have unique name so i want to give name as name_date_time.

So every time when package run new file is created with unique name.


Can any one suggest me who to create Excel file and fill result set data into Excel file.

And then finally send that Excel file ?







When dynamically creating an excel file, can SSIS create xlsx files successfully? I can only get SSI


Problem: An Excel file (XLSX) dynamically created by a SQL Task cannot be opened via Excel. The task succeeds, but when you try to open the workbook in Excel you get the fillowing error message: Excel cannot open the file 'myfile.xlsx" because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.

1. If the Excel file (xlsx) is created manually in Excel, then the SQL Task has no problem creating table (new worksheets) in the xlsx (so the "CREATE TABLE" statement works fine)
2. If I adjust the connection and task to work with Excel 97-2003 (xls) format then the approach works perfectly
3. The execution results show success of the SQL Task, but there are two warning messages. These same warnings appear when the SQL Task creates a new table (worksheet) successfully in a workbook (xlsx) which was created manually in Excel (and is not corrupt). Messages as follows:
Warning: Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.
Warning: Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.

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




Returning datas from two excel file



I used the below code to return the datas from one excel file. My question is if i suppose need to get the records from morethan one excel file using joins, how it is possible.

   string connString = ConfigurationManager.ConnectionStrings["xls"].ConnectionString;
        // Create the connection object 
        OleDbConnection oledbConn = new OleDbConnection(connString);
         // Open connection
            // Create OleDbCommand object and select data from worksheet Sheet1
            OleDbCommand cmd = new OleDbCommand("SELECT * FROM [Sheet1$]", oledbConn);
            // Create new OleDbDataAdapter 
            OleDbDataAdapter oleda = new OleDbDataAdapter();
            oleda.SelectCommand = cmd;
            // Create a DataSet which will hold the data extracted from the worksheet.
            DataSet ds = new DataSet();
            // Fill the DataSet from the data extracted from the worksheet.
            oleda.Fill(ds, "Employees");




Problem in accessing resource file dynamically.


Steps I have followed are
1.I have created myres.en-GB.resx file at C:.
2.then created locale specific myres.en-GB.resources using resgen at c: only,

Excel file getting error

Excel file not showing in search results

We have a strange issue. I have one Excel document (or at least one that I am aware of) that will not show up in search results for content within the document. I can find the document by title just fine, but when I search for words within the document I do not see it. The document was originally a 2003 Excel document and was recently converted to 2007. Other than that there isn't really anything unusual about it (some formatting stuff, but mainly just background colors and whatnot, nothing fancy). The crawl log shows the document was crawled without error. Anyone know anything else I can check on?

How to load a DLL Dynamically in c#


I have one application, where based on some functionality i need to load and unload dll's. For Example, if the user wants to perform some normal arithmetic operations then the application has to load Arithmetic.dll. If the user try to perform some trigonometric calculations then we will load trigonometric.dll. And these dll's can be updated at any point time. My application is running as a background process.


My problem here is, I am able to load DLL's but i am unable to unload them while my application is running.

I have tried Assembly.Load . It's working fine.Even i am able to unload also.  But i an unable to use serialization functionality.

Then I have tried Assembly.LoadFile . Only Loading  of DLL and Serialization is working properly. But i ma unable to unload it.


Please anybody help me to fix this issue or please give me thoughts on it.


Thanks in advance.
