when i convert tiff file to pdf in debug mode it converted successfully but when i host it on localhost it didn't convert and throw an exception:
Cann't make pdf files. Try again.System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {71DBCBF1-587B-42E4-9B30-74B80F4AA70F} failed.
I've been thrown into the middle of this project without knowing all the background. If you've got WTF questions, trust me, I have them too.
Here is the scenario: I've got a bunch of files residing on an IIS server. They have no file extension on them. Just naked files with names like "asda-2342-sd3rs-asd24-ut57" and so on. Nothing intuitive.
The problem is I need to serve up files on an ASP.NET (2.0) page and display the tiff files as tiff and the PDF files as PDF. Unfortunately I don't know which is which and I need to be able to display them appropriately in their respective formats.
For example, lets say that there are 2 files I need to display, one is tiff and one is PDF. The page should show up with a tiff image, and perhaps a link that would open up the PDF in a new tab/window.
The problem:
As these files are all extension-less I had to force IIS to just serve everything up as TIFF. But if I do this, the PDF files won't display. I could change IIS to force the MIME type to be PDF for unknown file extensions but I'd have the reverse problem.

Is this problem easier than I think or is it as nasty as I am expecting?
When I upload small sized tiff file(approx. 800KB) in my website folder on local system through fileupload control in asp.net. It uploads the file successfully. But when I upload 5MB or more in size tiff file. It can't upload file and display the following message.Internet Explorer cannot display the webpage.Here is my code:
if (FileUpload1.HasFile)

I got this error in a project I did a while back. I think this was a web site project that i converted to a web app project. This was a while ago. This is an app I'm trying to run on my local machine. I'm not using IIS.
Does anyone know what this means?
Error 2
It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

My website provides a facility to upload images, using the ASP.NET FileUpload control. We accept both jpeg and tiff formats but I have just decided that all tiffs should be converted to jpegs at the time of upload. If possible, I want to avoid saving the original tiff to disk. I would any sample coding for achieving this conversion prior to saving (ideally in VB.NET, though I could always run C# code through a converter).

I've add MSChart to a webpage and I'm also using a Survey page I got from 4GuysFromRolla (http://www.4guysfromrolla.com/articles/061604-1.aspx). Both work on my development machine but when I move them to my hosting site there are issues.
With MSChart page the chart is not displayed although it's included the Page Source code:
src="/ClubInformationTracking/ChartImg.axd?i=chart_3d90c53b0f844807a2491a1d79a636a1_0.png&g=75fecf0f14cf4121b623691d383263aa" alt="" style="height:300px;width:700px;border-width:0px;" />
And when I try to open the Survey page I get this:Parser Error Message: Could not load file or assembly 'sstchur.web.survey' or one of its dependencies. The system cannot find the file specified.
Source Error:
<%@ Register TagPrefix = "sstchur" Namespace = "sstchur.web.survey" Assembly = "sstchur.web.survey" %>
<%@ Page Language = "C#" %>
Assembly Load Trace: The following information can be helpful to determine why the assembly 'sstchur.web.survey' could not be loaded.
WRN: Assembly binding logging is turned OFF.To enable assembly bind failure logging, set the registry value [HKLMSoftwareMicrosoftFusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.To turn this feature off, remove the registry value [HKLMSoftwareMicrosoftFusion!EnableLog].
The Hosting site is using Version 4.0 and the dll needed for the survey is in the BIN directory.
When I moved my files to the hosting site I had to change every instance when I referred to a file from:
"~/FileName"
To
"FileName"
I've tried all of the "fixes" I could find for the MSChart that involved changes to the web.config file but because of the error messages associated with the Survey page I'm guessing this is the issue.

after i can copy my file to another folder i realised that if this webapplication is used by multiple users at once, then some users are going to get locked out because each one is trying to copy those files.
so how do i tell the user thats trying to use a file to wait untill the file is available.
StreamWriter WriterTotxt = new StreamWriter("date.txt", false);
DateTime LastAccess = File.GetLastWriteTime("path.dbf");
WriterTotxt.Write(LastAccess);

string ReadTextFile = File.ReadAllText(txtFile);
DateTime test = Convert.ToDateTime(ReadTextFile);
if (File.GetLastWriteTime(LatestUpdatedTime).CompareTo(test) > 0)
{
File.Copy(Path.Combine(sourcefile, fName), Path.Combine(destinationfile, fName), true);

I have built an ASP.NET (.NET v4) application in VS 2010. It is working just fine. But when I try to create deployment package (so I can deploy it in our test IIS 7.5 Server), it gives me error like this,

Thing is in past, I had deployed the SAME application using the SAME method.
I'm retrieving a binary file from the database, a .pdf file that I would like to let the user open and view. From what I can tell, there are two steps to do this:

When debugging my application, I m getting an application level error in global.asax file. The Server.GetLastError() reads "File does not exist." but thats it. No more details on the filename or the location where the code is trying to find a file. I commented out the application_error method, with a hope that the exception would be thrown when the debug the application, but no errors were thrown. How do i find the source of the error, cos I want to resolve this issue by either putting the file that the application is looking for or by completely removing the code that is referencing the file.

whenever i m trying to upload more than one file i m getting this error "Cannot access a closed file. ". The file size is very small, the format is also .doc, .xls. The first file is uploaded correctly, no problem at all. The problem arise when system tries to write second file. Any ideas? On upload button event, I have taken all the files in httpfilecollection which i assign in session so that after attaching i can upload it later on save event. Problem occurs in save event that too on remote server. It's not happening on my local system.
