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.
My client asked for encrypting some information form their payment system to prevent user stealing personal information. The system is web-base and written by ASP.NET
We have tried some annoying solution such as JavaScript no right-click or css-no-print but apparently my client didn't like it.
so are there any commercial solution to encrypt information in aspx produced html pages?
or someone can tell me how to pursuit my client to stop these "prevent stealing" idea in a web-base system?
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?
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?
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.
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.
dim filepath as string = "http://order/venommain.asp?f=N&username=0E3706&password=0E12Y6&docs=-1&folders=-1&sv=&e=-1&nw=&q1=TITLE+CONTAINS+PDFFILENAME"
response.redirect(filepath) // it works and open PDFFILENAME
But,
System.IO.File.Exists(filepath) alway return false (it should return true)
How to code to detect the file existing in http format?
How can I retrieve file information (size of file) before it is uploaded to the webserver?
I would like to create a multi file upload. I have it working in JQuery but I would like to know the size of the files to set a limition by summing up the total the file sizes together.
My users like to upload password-protected Word documents into our custom document management system. I'd like to add a validation to check for the password and refuse the upload if it has a password.
Automating Word - with COM interop - is out of the question because this is a server side application.
I'm looking for detailed technical information on the compilation process for aspx pages and vs2008.Recently I have been learning about controlbuilders and pageparserfilters. I have downloaded some code to clean out extra white spaces in my html in order to make the pages smaller. The code works great, but I don't understand WHY it works. I need to learn more about the page compilation process.
i want to show info like how much time will be requited to download file in client machine. every client will have different internet speed so how can i detect and show time required to download file in client machine. is it possible in asp.net.
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).
i have some problem on downloading file which file types are .doc, .docx and .pdf.
I have wrote the code for downloading when the button is click. the button can download these three types of file when click.
[Code]....

How btnSave is being recognized by .cs file without defining it anywhere as an object of System.Web.UI.WebControls.Button?
When I update a js file in my asp.net project, I refresh the browser and the change shows up as expected. If I change a css file or an .aspx file, the change does not show in the browser. Not when I clear the browser's cache, not when I restart IIS (iisrestart). What could this possibly be?
I work in VS 2008. Whenver I add a server control(Label) and set it properties in aspx.vb and build the solution, I get the error "Label1 not declared". While analyzing this issue I noticed that the event handler statements for the Label1 where not added in the designer.asp.vb file. These statement would actually be added automatically when I drag and drop a control to my webpage.
I would also like to inform the scenario after which this problem came to me. I was working in VS 2008 , VS 2005 and VS 2003 in the same machine.Could this have caused the issue ?
Now each and everytime when I add a control, I am adding the "With Events" code in the designer page to make my build succesfull which makes me to spend more efforts.
