Problem with uploading a zip file containing xls with macros

I am getting the following error when I try to upload a zip file containing xls file with macros. The zip file size is 4 mb. However, we have SP 2010 environment (ready to be deployed in couple of months) and it works there. So, it is not to do with the file. I am not sure if SP 2007 has any limitations/restrictions with .xlsm files. How do I fix this issue ? "GILA_Reports_File_byGTStar_9_2010.zip" contains the following virus: "Large uncompressed size; Tagged ID: C57E7332_69BC_484A_B087_DB04D574CDC4" . This file cannot be saved to the document library. If you want to save this file to the document library, clean the file using alternative virus scanning software and try saving it again.

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




Problem in accessing resource file dynamically.


Steps I have followed are
1.I have created myres.en-GB.resx file at C:.

            string sdf = res.GetString("Lab1");

File Download Problem


Hi everyone,

I am using a download handler to handle the downloading of files from my website.  I am using a slightly modified code from the Microsoft article http://support.microsoft.com/kb/812406

Everything is working fine and downloading, even with large files, but it does not show the file size for any of the files to download. Even if theyre really small.

Here is my code for the handler

public class DownloadHandler : IHttpHandler

        public void ProcessRequest(HttpContext context)
            string path = "";
                path = context.Server.UrlDecode(context.Request.QueryString["src"]).DecryptString();
            catch(Exception ex)
            System.IO.Stream iStream = null;

            byte[] buffer = new Byte[10000];

            int length;

            long dataToRead;

            string filename = System.IO.Path.GetFileName(path);

                iStream = new System.IO.FileStream(context.Server.MapPath("~/" + path), System.IO.FileMode.Open,
                            System.IO.FileAccess.Read, System.IO.FileShare.Read);

reading excel file problem



i have 200 rows in my excel file. im using OleDbConnection to read the excel file.

The problem is that it will read all the blank rows from row 200 onwards. Is there a configuration im missing ? or is there a way to import all rows that has data? Here's some of my code.

string excelConnectionString =
               "Provider=Microsoft.Jet.OLEDB.4.0;" +
                "Data Source=" + filePath + ";" +
                "Extended Properties=Excel 8.0";

OleDbConnection excelConnection =
                    new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filePath + ";Extended Properties='Excel 8.0;HDR=NO'");

OleDbCommand cmd = new OleDbCommand("Select * from [list$]",excelConnection);

Generating MS Word doc from mht file gives smart quote problem


I have a word document to be generated using ASP.Net/VB.net.

So I have a word document template saved as .mht file on the web server.

In my ASP.Net code,I read this mht file content and replace certain string line Description$$ with the actual description from the database.Then save this content as .doc file.

This works fine but shows a box symbol when I have smart quotes " (not this one as I cannot type it here.The double quote which you see in MS Word,the slanted double quote).

I dont know how to make my word doc generated, show the exact double quote as in MS word.

If any of you have any idea of this please reply.

Thank you

Problem when using Activator.CreateObject and reading App.Config file

Hello, this is the scenario. I have an application that load at runtime severals dll. these dll are actually "adapters" that wraps calls to web services, database and so on. The app.config of the "main" application stores in config sections all information necessary to each adapter (i.e.Web ServiceURL..) and I have created inside each adapter a class to ready those values the loading at run time the DLL has been implemented by storing all necessary types into a dictionary of generics and when I need to instanciate it I call the Activate.CreateObject and I pass the specific type (I means the name of the Adapter class) The problem is that the adapter class itself is not able to get the config value because ConfigSection has not been initialized. If I write: IInterfaceAdap adapt = new myAdapter() -> I read the config data IInterfaceAdap adapt = (IInterfaceAdap)Activator.CreateObject (type) -> now way to read the data stored in the App.Config. I think that I undertood the problem but I'm not able to find a workaround to read data store in the app.config!! I need help please!!  

Access to path xxx denied when uploading a file using c#

Hi I have a file upload app written in c#. The app runs on IIS on a Windows 2003 Server OS. I want the app to upload the file onto the server (The app and the server are on the same machine). This code has been working fine for a long time running on Windows Server 2000, and Windows XP Professional. Now when I moved onto Windows Server 2003, it stopped working. I have given ASPNET account full access to the folder on the server, and it still gives this error. Is this a bug in 2003, and can anybody assist me? Thanks Shane

Web Folder problem : This file cannot be saved to this location because there is no connection to th

When I check out a Word 2007 document from a list, I cannot save it back to the server.  I get:   This file cannot be saved to this location because there is no connection to the server.  Check your network connection and try again.   I am using a Virtual Machine (Virtual PC).  I have the Microsoft Loopback adapter installed.    The server has a static IP address and is a domain controller.

Uploading a file to a document library produces access denied error, but only on first try.

Hi I have a task which uses a custom form which is part of a custom workflow.  The form incorporates an asp fileUpload control to allow a user to browse for a local file which they can then select and it will be upload a file to a folder in a document library.  The first time this action is performed the folder in the document library will not exist so the code creates a folder and then uploads the file to it. The problem I have is, the first time users try and upload a file the directory is created in the document library as expected, but then the user gets redirected to the standard SharePoint Access Denied page.  If the user goes back to the task list, then loads the task web page again, selects the same file and hits upload, then the file is uploaded fine. All subsequent file uploads work fine after that for all users. Users have Contribute permissions on the document library. The code to do the upload is as follows.  The task has a "CR Number" associated with it, which the directory in the doc library should be called.  It uploads the file to a stream.  Then gets the url of the web and works out the file url and uploads it.  The creation and checking of the folder in the doc library happens in the getDirUrl method. /// <summary> /// Processes an uploaded file. /// </summary> /// <param name="
