i hav an web app that gets data from user and writes it in a file.
the issue is many users can launch the application at the same time and hence many can write to the file.
but the file is at a shared path and hence only one copy is used by all. I want to restrict the number of access to the file at a time to 1.

View 3 RepliesI want to access one image file residing in C: of the client's machine. I know with the help of file upload control (or say input type=file), this would be easy. Due to nature of my application (Its a KIOSK application), user is not expected to select file. I am just wondering how should I implement reading file without using file upload control. I want to store this file in Images folder of server. I am beginner to WCF. Should I look towards WCF?

View 3 RepliesI've been worked with web services so far, and I'm interested in expanding my services to console applications as well so I started digging up with WCF but I'm conserned that I won't be able to use the HttpContext collection that I've been used to do with web services one important thing which is to generate a random value from HttpContext.Current.Request.ServerVariables["ALL_HTTP"] that I need to reckon if it's the same or at least near what machine that is calling my service. How can I overcome this problem?
I need to know what machine is calling to count the number of attempts to login into my system for example. So must do it inside of the svc code otherwise if I let the client inform what ip address or what computer he is using, anyone could forge this argument and surpass by another machine. May be I'm approaching this matter wrongly. And I should count the number of attempts per state session, but how is it done?

View 5 RepliesI have an issue with trying to create a Pdf file from my webpage. Basically, everythig involving creating the Pdf (using iTextSharp) is done, and I'm doing this as a File Stream (i.e, I'm saving the Pdf on local machine). Now what I'm trying to do is create it as a Memory Stream (i.e, open the Pdf from the browser). I was able to do this earlier when I wa still at the 1st version of the application, and all of the code behind was incluced in my .aspx.cs file. But now, I've kept the code in the .aspx.cs at a minimum and put the cude in classes and I'm creating onjects of thoses classes from the .aspx.cs
The problem is that the code from creating the Memory Stream is in a class as follows:

As you can imagine, the compiler cannot recognise "Response" as it's in a seperate class instead of in .aspx.cs
I've been searching google for recommendations on conventions or best practices when it comes to the 'case' and naming of files on folders within a Web Application.Most of the time I work within Visual Studio, developing ASP.NET web applications.

I have developed a Web application in VS2008. It works perfectly on my development PC. When I publish and upload to the shared Windows hosting service (which supports ASP.NET 3.5), it fails (even when accessing it from my development PC). The error message is: Could not load file or assembly 'Microsoft.mshtml, Version=7.0.3300.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.I have read many forum posts on the subject, and have tried the recommended solutions:
Set the reference to Copy Local - VS2008 does not allow Copy Local for ASP.NET references, just for WinForms references.Copy mshtml.dll into the installation directory - I have tried 3 different versions of the file, both in the root directory and /bin/, under both the names "mshtml.dll" and "Microsoft.mshtml.dll". None work.install the Interoperability Assemblies from Visual Studio onto the server by running "vs_piaredist.exe" - I don't have admin access to the server and the hosting company won't do it.
