Unable to upload/attach any file

Posted By:      Posted Date: August 31, 2010    Points: 0   Category :SharePoint
We have a developing Sharepoint server with SQL Seerver 2005 standard as a db server. Eventually server stopped to accept uploading any file into any library or attaching to any list item on all application poolls and site collections.

Unable to upload .flv file on IIS 6.1


Hi guys,

I've been trying to upload a video file on my local harddrive and it seems it cannot process the upload. The .flv MIME type is already registered on my IIS but still it cannot process upload.

Any inputs would be a very big help.

Here's the screenshots.

Unable to upload report file to SSRS 2008 R2 Express

I'm attempting to upload a report file into an instance of SQL Server 2008 R2 Reporting Services (Express edition), and I'm having difficulty. While I can do things like create folders and manage security, I am unable to upload a report definition (.rdl) file from either the web console or via the ReportService2005.asmx web service. Both avenues eventually time out and generate a 401 error (though I am not sure that this 401 is legitimate, as it takes over a minute and a half to generate the error).

This instance is running the web services on a non-standard port (8080) in HTTP (not HTTPS) mode, as it's on a Windows XP Pro machine with an existing website on IIS.

I have looked at the report server access log, and this appears to happen when it errors out:

    rshost!rshost!380!10/13/2010-14:39:10:: e ERROR: ReadCallback(): failed to read in read callback.

Upload a File to a SharePoint Document Library - Part I

The following helper class demonstrates a few techniques that allow documents to be uploaded to a SharePoint document library programmatically without using the API or a custom web service. You don't need to specify a document library name, and it will create any folders specified in the URL as required. File meta data will be updated if any properties are passed.

unable to attach database, security setting?


Hi folks,

I am using VS 2010 Professional with SQL Server 2008 Developer.  I right click on the App_Data folder in solution explorer and add an existing item, then navigate to the correct database.  However, I receive a pop up that Access is Denied.  How do I fix this? 

Asp.Net upload file access denied



I have the problem below, if anyone can help me, appreciate it.

Server Error in '/' Application.

Access to the path 'c:\Inetpub\EnewsAttFiles\employ-e-header2.jpg' is denied.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access to the path 'c:\Inetpub\EnewsAttFiles\employ-e-header2.jpg' is denied.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Hig

File Upload to an .ashx Script.


Hoping that someone can help me with this. I've been tearing my hair out for days looking for sources and coming up with nothing.

Basically, the scenario is this: I'm working on a project whereby an iPhone will make an HTTP-POST call to an .ashx file on my site. The POST will consist of some fields and a file.

I'm having difficulty - read that as no luck what-so-ever - in finding the form fields or the file when I look at the HTTPContext object in the debug mode of Visual Studio. And if I look at HTTPContext.Request.Files.Count (where I would expect to find a file count) the value is always zero!!

Please help, very confused by this!



why I can not upload file to web by using WebClient.UploadFile method?



I am using WebClient.UploadFile method to upload a file to a web page.

The code is like this:

WebClient client = new WebClient(); 
byte[] responseBinary = client.UploadFile(url, fileName); 
string response = Encoding.UTF8.GetString(responseBinary);

But I can not upload it to server.

I used fiddler to see what happens, and it shows me the following information:

http status code: 302, request headers: POST /testing/upload/default.aspx HTTP/1.1

http status code: 302, request headers: GET /testing/upload/default.aspx?AspxAutoDetectCookieSupport=1 HTTP/1.1

http status code: 200, request headers: GET /(X(1)S(22pynhvxd3eqsb455pudx145))/testing/upload/default.aspx?AspxAutoDetectCookieSupport=1 HTTP/1.1

I would like to know, why I get 302 code, and why it redirect me to the strange url with (X(1)S(22pynhvxd3eqsb455pudx145)) ?

By the way, the web page is ok to upload file by using web explorer.
