uploading a file with wcf works fine with local drive, but only 4096 kb uploaded when I use unc stor

Posted By:      Posted Date: September 17, 2010    Points: 0   Category :WCF
Hello I'm writing a wcf service for uploading files to a server. It works fine when I try to upload the file to the servers local c:/ drive, but if I use a UNC path only 4096 kb is stored. It actually looks like part of the file is lost while storing it with writeStream.Write(buffer, 0, bytesRead);, because I wrote the bytesread to an sql table and the number of elements are always the same no matter how many times I upload the file, but the stored file is always different sizes, ranging from 1996 kb to 4092 kb.   I'm using IIS 7.5 on a windows 7 enterprise machine. My IIS is using a administrator account for the application pool, so it should not be a problem with permissions.   My wcf method uses Stream to upload the file in chunks    public void UploadFile(RemoteFileInfo request)         { //some methods to set the filepath                                   int chunkSize = 4096;                                 byte[] buffer = new byte[chunkSize];                                 Stream writeStream = new FileStream(filePath, FileMode.CreateNew, FileAccess.Write);  &

Error Running SSIS Package as SQL Agent Job loading a file from network drive, works fine in bids an

Having problems reading an excel file from a networked drive while running a package as a SQL Agent job step as a type "SQL Server Integration Services Package". I have agent running as an AD account, and I can use the execute package utility logged in as this account and it works. When I log into the server as this account, I can see the network drive, read/write/create to folders on the drive but when I try to run the agent job it cant find the file. I tried using the unc path in the config file rather than a mapped drive, still no luck. If I use a local drive (c) in the config file, the job works fine so it has to do with the network drive. Running windows server 2003 standard R2, SQL Server 2005 standard sp3. Any ideas out there?

FileUpload works fine, but uploaded files have restricted access



I'm using the asp FileUpload control, which uploads the files just fine. However, once the file is in the system (say a pdf) it can't be accessed from the web... I check the file security and access to the file is restricted. But no folder that it's in is denying access to web users.. So how can I stop this auto-deny-access from happening?

Trying to launch a .exe file on my local computer from intranet site.


I have been told I can launch a local program on my PC from my intranet site but it has to be done with Active X or vbscript and not javascript.  I found the following little sample html code that will launch notepad.  However, I cannot figure out how to put this in a button, etc., within my aspx or code behind to execute it.  Does anybody have any idea how to do this?  I have a lot of javascript code I am launching urls with and I have even tried using that but again, I have been told that to do it client side it needs to be vbscript or something like this.  Any ideas?

Word save file on SharePoint via mapped drive


Hi, I have a Document Library mapped to a drive letter. I am able to browse the drive through Windows Explorer. However when I try to save a document to the drive Word returns, 'Unable to connect to the Web server.' .  I have been unable to find any information regarding this error message. If I try to create a document in the Document Library through Windows Explorer and the mapped drive, I get a different error message: 'Unable to create the file 'New Microsoft Office Word Document.docx' There is no user session key for the specified logon session.' After I click OKand refresh the directory, a 0 KB New Microsoft Word Document.docx file has been created. When that file is opened, it is in Read-Only mode.

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

Can't connect to SQL 2005 Enterprise using Management Studio with Server Name (only (local) works

This is a test system, everything running locally & no domains. Win 2003 Ent. Server & SQL Server 2005 Enterprise. I can't log into SQL Server Management Studio using the server name & using either Windows Authentication or SQL login. If I change the name of the server in the drop-down list to "(local)", I connect just fine (both Windows & SQL security modes). Shared Memory, Named Pipes & TCP/IP enabled in both server & client. Remote connections allowed. I have IP adresses (both & external IP) in my hosts file pointing to the server name. Does SQL require a DNS server? This wouldn't be a problem except for the fact that I can't install SQL 2005 SP3 due to authentication failure since there's no way to enter (local) as the server name. SQL tools (management studio, SP install) seem to see the SQL server running but won't authenticate the user through any means other than setting server name to (local). This is driving me crazy!!!

Cannot read stream from uploaded file

I have a file upload which uploads a file and gets read into a byte array.int FileLength = File1.PostedFile.ContentLength; if (File1.PostedFile != null && File1.HasFile) { Stream fStream = File1.PostedFile.InputStream; byte[] contents = new byte[fStream.Length]; fStream.Read(contents, 0, (int)fStream.Length); fStream.Close(); fStream.Dispose(); The problem is, the fStream.Read seems to have a problem reading the stream. When I debug it, and the value of "contents" appears to be empty. The file gets uploaded as a corrupted file.  

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="
