Error opening excel files stored in SharePoint 3.0 from VS2010 (TFS2010 setup)



First I hope this is the correct forum for te below question, and if not, please excuse and if possible divert me to the correct place.

We have a TFS2010 setup with (what I managed to identify) Sharepoint Services 3.0.
We have 2 users working in the same collection, and also share some of the projects in it with the below problems:

1. User A has Office 2007. She is unable to "edit workbook" on an excel file directly from VS2010, and gets an error of 'Unknown error trying to lock file'. I searched this around and didn't find a solution, but did find a workaround - If she checks out the file directly from the SharePoint site, she is able to edit the file, and in fact is able to later "edit workbook" directly from VS2010 (as long as she once checked it out through SharePoint).

2. User B has Office 2010. When he tries to "edit workbook", he gets an error of 'A problem occurred while connecting to the server. If the problem continues, contact your administrator'. When he goes directly to the SharePoint, he is able to check out the file, open it in Excel 2010, but is not able to check it back in (gets an error that the file cannot be located or so, I don't have the exact error). This means that this user cannot work with the SharePpoint stored files at all, and currently works on local copies on hi

Error when trying to export gridview to Excel - RegisterForEventValidation can only be called during

I have a pretty basic vb.net page that has textbox control on it and a "generate" button that when clicked, fills a datagrid.  That all works great, but when the user clicks the "Export to Excel" button, I get this error.. RegisterForEventValidation can only be called during Render(); 

Here's my code behind, I thought I included everything I needed...

Public Overrides Sub VerifyRenderingInServerForm(ByVal control As Control)
End Sub

        Response.ContentType = "application/vnd.ms-excel"

Error Handling loading Excel Files with SSIS 2005


I have an SSIS job which watches a directory for new files being submitted. On detecting a file(s) it determines the process to perform on it (based on the file name) and then reads in the file, loads it into the database, and deletes the file. All is fine. I want to add error handling though, specifically for the instance where the worksheet name does not correspond to that defined in the Excel Connection manager for this file.

At the moment if I change the sheet name to be different to that defined in the connection manager, the job fails and so (in turn) the whole process ceases (i.e. the for loop also goes to status failed).

I have tried event handler variables and checkpoints but without success. Could someone give me some advise, or point me to a article that would help?


Export to Excel gives error before opening file


I have a web page with a gridview control and a button for Exporting to Excel

I get following error when exporting to Excel.

"The fiel you are trying to open, 'someFileName[1].xls, is in a different format than specified by the file extension. Verify that file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?"

Clicking Yes opens the file. I would like to avoid showing the above error to the users.

Following code is used from the click event. I've left the commented code here to show what I've tried based on results from internet search. I have Microsoft Office Excel 2007 on local PC.

public static void ToExcel(DataTable dt, string fileName)
			string attachment = "attachment; filename=" + fileName + ".xls";

			GridView gvExcel = new System.Web.UI.WebControls.GridView();
			gvExcel.AutoGenerateColumns = true;
			gvExcel.DataSource = dt;

			//HttpContext.Current.Response.AddHeader("content-disposition", attachment);
			//HttpContext.Current.Response.ContentType = "application/ms-excel";
			HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";

Uploading Large files via Web Service | HTTP Error 413 - Request Entity Too Large.


Hello all -

I am trying to implement a Web Service, which accepts a binary file as a byte array for one of its parameters.  It's workings are based on this article:

Anyhow, the size of the file can be significant as the types of files being uploaded through the service are MP4 Video files.  The service works on my WinXP SP2 localhost, but when I implement it onto a 2003 Server and try to consume the service, I get the following error back from the web service:
The request failed with HTTP status 413: Request Entity Too Large.

I do a little searching around and find a few articles indicating that I need to adjust my "MaxReadAheadLength" property in IIS.  A good example of one of those articles is here:

The suggestion from the article is to execute the following command on the web server:
cscript adsutil.vbs set w3svc/1/uploadreadaheadsize 204800 

FYI, the adsutil.vbs is in your IIS's AdminScripts directory.  I'm guessing that the /1/ part of the command is th

Export Visio Database Table Names to Excel

If you use the Enterprise Architect edition of Microsoft Visio for data modeling regularly, then there is a good chance that at some point you've wanted to export just the table names into Excel. You might want to do this to map logical ERD entities to physical data model tables, track project status by entity, or track overlap between database versions.

HTTP Error 403 - Forbidden


(VB Express website directed me to ASP.NET Web Services which in turn redirected me to this forum).

 Hopefully someone can help me here...... 

I am using VIsual Web Developer and downloaded the small business application to use as a starting point to help my wife get a website up for her small business. When I load the application, I can F5 and it runs fine but as soon as I make any modification to the app and hit F5, I get the HTTP Error 403 - Forbidden when it tries to show the website.

I notice a pop up that occurs when I run that allows me to choose the link for my app and it displays correctly (I close the webpage that has the error on it).

This seems like a pain, is there a setting I'm missing - I would think that this should "just work".

What's up?????
