I try to read zip archive from stream and extract files. Got the following exception in the line "using (ZipFile zip = ZipFile.Read(inputStream))" : ZipEntry::ReadDirEntry(): Bad signature (0xC618F879) at position 0x0000EE19. how to handle this exception?

I have an excel file in my Response Output stream. I can Open the stream as a file after a prompt, but it doesn't seem I can save it directly to a specified folder on my client.
I am trying to create a zip file and save it using DotNetZip library.
But for some reason i get a "Access to the path is denied" error when i try to save it. Code4 is below
Dim zipFile As New ZipFile() zipFile.CompressionLevel = Ionic.Zlib.CompressionLevel.BestCompression zipFile.AddFile(filePath) Dim tempFilePath As String = "abc.zip" zipFile.TempFileFolder = "D:Company DataOperationsmedia est_folder_cover_scan" zipFile.Save(tempFilePath) <== error line
I have given all possible access to the folder. I am using .net 3.5. This whole code works in a web service

I trying dotnetzip on localhost everything works fine.but on a real dotnet hosting it raises error :

This may be something simple, but I am completely new to ASP.NET. I have been reading some tutorials based on W3Schools, and I have copied one of the files and tried to play with it by changing an element with a value to storing that same value in the attribute. Here is the edited XML (my.xml):
Is there a reliable way to extract text from PDF? The first thought that comes to mind is that PDF may have multiple columns and the extraction mechanism needs to know the logical structure somehow. I understand that some PDF docs are "tagged" but I'd need to support pretty much any PDF document.
I found an application that interacts with one of googles APIs that sends requests to the API and returns results to the web page. The owner of this app has made it publicly available and even though it is hosted on his server, it acts directly with the api from anyones browser. The source code in page source is available but since I dont know javascript, it is meaningless to me.
I would like to create an app that calls this web app and have it send requests to the API, and have the results parsed to a database. Would this be possible?
I have very little ASP experience and since trying to work through accessing the API itself is complicated since it involves using oAuth protocol and I am having a hard time with this with not much sample code available.
If this is possible, how can I get access to the results from this web app?
Every morning we get a few hundred emails from our various customers servers that tell us how their backup went that previous night. Somebody has to go through these and fill out an excel spread sheet. I would like to automate this, we have our own server running a .NET application so i can schedule something every morning.
There are two main parts. The first is i want to know how to create a table that has customers down the left and dates accross the right, they are called pivot tables in access but not sure how to recreate them in MSSQL and to do it on the fly as i dont want to have to sit there entering 100's of days at a time.
The second is that differnt customers use differnt backup solutions, so i want to write some code that scans a particular mailbox in exchange, looks for emails that have come in in the past 12 hours, look at the from email address and match that to one in the database, then according to the subject line it will be able to identify what type of backup solution it is, e.g. if it says "Backup Exec Job completd Sucessfully" it knows its backup exec and will look for a particular text (completed successfully, completed with exceptions, no media etc) and can insert that, or if its a differnet backup solution then go and look at a specific place in that email for it.

I want to fetch only the date element from this string. i.e 11/24/2010 1:02 AM
I know i can do that using the substring method of string class but i need to implement a standard solution for this problem. i.e. fetch date from any html content if it contains a date element.
I have a requirement wherein a SQL query will be given in a text file.
The text file has to be read , the SQL query needs to be parsed and the column names, table names and where clauses have to be extracted and inserted into separate tables.
i am using the below code for extracting paragraph for matching string.
[code]...
i am getting correct result,but i am getting breakable words in starting and ending paragraphs like "...ing regions uses the and Boolean connector to specify the region so narr..."
I have a Portable Bridge Notation formatted-file that I have to work with. I have already a few simple examples working by using indexing and substrings extracting what I need and I suppose for this PBN business it would suite me well since it isn't run too often. If I one the other hand would run that code like all the time (thinking of working with vCards) then I am worried about memory usage under high workload because of the high amout of temporary string variables created from all substrings and splits.
There are two other options available that I know of. Regex and StringReader / TextReader and I wanted some general opinion on what to use.
Intended usage is to extract to objects and serialize to json so that I can more easily work with or persist this information. Hell if it's fast enough I might even do it on the fly.
The task is: given a web application that returns a table with pagination, do a software that "reads and parses it" since there is nothing like a webservice that provides the raw data. It's like a "spider" or a "crawler" application to steal data that is not meant to be accessed programmatically.
Now the thing: the application is made with standart aspx webform engine, so nothing like standard URLs or posts, but the dreadful postback engine crowded with javascript and non accessible html. The pagination links call the infamous javascript:__doPostBack(param, param) so I think it wouldn't even work if I try even to simulate clicks on those links.
There are also inputs to filter the results and they are also part of the postback mechanism, so I can't simulate a regular post to get the results.
I was forced to do something like this in the past, but it was on a standard-like website with parameters in the querystring like pagesize and pagenumber so I was able to sort it out.
Anyone has a vague idea if this is doable, or if I should tell to my boss to quit asking me to do this retarded stuff?
EDIT: maybe I was a bit unclear about what I have to achieve. I have to parse, extract and convert that data in another format - let's say excel - and not just read it. And this stuff must be automated without user input. I don't think Selenium would cut it.
EDIT: I just blogged about this situation. If anyone is interested can check my post at [URL] and comment about that.

I have a textbox that gets the date from an AJAX Calendar extender. What I need to do is extract the "month," "day," and "year," and put them into seperate string variables to use in my code to do various things based on the month, day or year respectively.
Here is what I have so far:
[code]....
But I don't want the year NOW, I want the year from the textbox.
