C# - How To Detect If A File Is PDF Or TIFF

Apr 28, 2010

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?

Detect New Aspx File And Get Information From Them?

Jul 24, 2010

I'm developing a website that has modular section. I would like it that when a new aspx (and aspx.cs) file is placed in a subdirectory of the application that I can ask the class some information...The idea is that when the file is placed in the directory a new menu item is added to the menu. To do that I need to "ask the class" for its name, icon, description, etc. Is there a way to determine the class that is defined in codebehind file and to instantiate an instance of it?I know I could look for and parse a config file for each plugin but I would rather not have to go that route.

Detect The Encoding Of An Excel File?

Sep 30, 2010

using vb.net/asp.net 2005

I am opening and reading and I need to detect the encoding of the file that I am reading. There are different system users who will be using different encoding in their files so I have no control over this.

[Code]....

While the default encoding normally works there are special foreign language (non-English) characters that are not being read correctly, instead there are garbage characters in their place that I see "myString" above. Good foreign characters are visible in the file but the result in myString are unreadable garbage characters that are not valid.

I have researched this and it has been suggested to determine the encoding of the file and then use that encoding, but I have not been able to find out how to to do this.

so in a nutshell: how can I use vb.net to detect the encoding of an excel file?

C# - How To Detect That A File Was Successfully Received By A Webclient

Feb 18, 2010

My question is similar to http://stackoverflow.com/questions/194579/how-to-detect-when-a-user-has-successfully-finished-downloading-a-file-in-php but I have to do the same using IIS, ASP.NET and C#.

None of the methods in the HttpResponse class provide feedback if the data was sent or not, TransmitFile just does its job (or not) and does not provide any means of knowing the result.I was thinking of using the .Filter property but then again, the filter is based on the HttpResponseStream which does also not provide any feedback.

Make IE Detect File Type Without Extension?

I'm trying to let the user download different documents where the data is stored in an SQL DB. In firefox, the filetype is correctly read, but not in IE. I'm trying to do this without having to set the ".pdf" or whatever extension the document has, because I haven't got that information. I only have the filetype.

C# - Save A Binary File In SQL Server As BLOB And Text (or Get The Text From Full-Text Index)?

Mar 26, 2010

Currently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions.Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types?-or-Is there a way to pull out the raw text from the SQL Full text index, without using 3rd party filters?Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene

AJAX :: How To Detect When A Media File Has Finished Loading In Modalpopupextende

Dec 8, 2010

I embed wmp, swf, and qt in a modalpopupextender. Some of the video files take a long time to load so a given player's window stays empty for too long. I think I should be able to have the player hidden initially and display an animated gif in the modalpopupextender and then when the video files completes loading I'd hide the gif and show the player (or simply manipulate the corresponding z-indexes).

VS 2008 - Reading Contents Of A Text File Into Text Box On Form

Jul 13, 2011

I'm trying to read the contents of a text file into a text box on my form. When I run the following code, nothing happens.

VB.NET Code:
Protected Sub lbLogs_SelectedIndexChanged(ByVal sender As Object,
ByVal e As EventArgs) Handles lbLogs.SelectedIndexChanged       
For Each li As ListItem In lbLogs.Items           
If li.Selected Then                Using sw As New StreamReader(li.Value)                   
txtLog.Text = sw.ReadToEnd                     sw.Close()                End Using            End If        Next    End Sub

I populate the ListBox with ListItems and each ListItem's Value property holds the full path to the file. But, I removed all of that and just put txtLog.Text = "test" inside of the "is selected" block.

Long Running Web Page - Generate A Text File Conforming To A File Specification?

Jul 8, 2010

I have an application I am trying to write that generates a text file conforming to a file specification, and the file could contain thousands of lines. This part is easy. The more challenging part for me is the user interface. It needs to be a web interface with various options to affect what data gets on the file; this part is no problem. The process for generating the file, though, could take a little time depending on the amount of data , and I would think the web page would time out.

What options do I have for the UI? Could I create some sort of service that the page calls and runs in the background? When the process errors or is finished, I'm thinking there could be an email sent out, or even messages displayed on the page.

Intermittent Bug - IE6 Showing File As Text In Browser Rather Than As File Download

Dec 30, 2010

In an ASP.NET WebForms 2.0 site we are encountering an intermittent bug in IE6 whereby a file download attempt results in the contents of the being shown directly in the browser as text, rather than the file save dialog being displayed. Our application allows the user to download both PDF and CSV files. The code we're using is:

HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.AddHeader("Content-Disposition", "attachment;filename="theFilename.pdf"");
response.ContentType = "application/pdf";
response.BinaryWrite(MethodThatReturnsFileContents());
response.End();

This is called from the code-behind click event handler of a button server control. Where are we going wrong with this approach? Edit Following James' answer to this posting, the code I'm using now looks like this:

HttpResponse response = HttpContext.Current.Response;
response.ClearHeaders();
// Setting cache to NoCache was recommended, but doing so results in a security
// warning in IE6
//response.Cache.SetCacheability(HttpCacheability.NoCache);
response.AppendHeader("Content-Disposition", "attachment; filename="theFilename.pdf"");
response.ContentType = "application/pdf";
response.BinaryWrite(MethodThatReturnsFileContents());
response.Flush();
response.End();

However, I don't believe that any of the changes made will fix the issue.

Read Large File Size Text File?

Jan 17, 2011

I have a text file with tab as delimiter. There are about 20 fields in the text file and the file size is about 150MB-200MB.

I need to filter out each row in the textfile based on its field criteria, For Eg: the i should ignore the particular row if the Field A is empty.

I know that by reading out the text file row by row it will be certainly slow.

how to read out the text file fast and also how to do the file processing for the read out text file?
