created an application that accesses some external APIs (google earth api). When I run in VS, everything works. When I run my application on another computer, I get the error:
[Code]....
I have both VS 2005 and 2008 installed on my machine. 2005 is fine. For 2008, literally any asp.net project I try to create gets this eror. I try stepping into the code, and the error occurs apparently before anything that I can trap is loaded. There is no information written to the event log. I have tried this with a "Hello World" webpage with nothing else going on. Seems unique to my Windows Server 2003 machine.

I am maintaining C# .NET code written by somebody else, I get following exception few times,Attempted to read or write protected memory. This is often an indication that other memory is corruptThe code structure where I get the above exception is somethign like this,- it is using ref variables in following sequence,Variable-1 and variable-2 are local variables in App1, - App1: func1() which passes these variables reference to func2(), - App1: func2() passes same variables reference via .net remoting to another application (App2).-App2: does the same passes same received reference to another call 2 times.- The execption is occured while returning from App2.
(App1:func1(ref Var1, ref Var2) --> App1:func2(ref Var1, ref Var2) <---App1 .net remoting to App2--> App2:func3(ref Var1, ref Var2)--> App2:func4(ref Var1, ref Var2)-->variables getting updated and function returned to original caller)
My doubts are ,1. Is passing reference variables in such chain is correct? will it cause such exeption? Does .net support ref variable call directly?

I am working on a web app that will heavily rely on configuration. The configuration is also will be written by another process or human. I am looking to get response on best practices in .net 3.5 on how to implement this case. I had used the configuration section of an early version of the Enterprise Library Applications Block. I really liked working with it but from what I hear it is discontinued in current versions. Hence the question... Need to be able to serialize collections, pick up file write event to reload new instance of config into memory.
View 1 RepliesI'm using VS2010 and need to give my remote server asp .net account (IUSR_istereos) access to my local intpub folder
how do I do that?
I use dynamic currency symbol(Doller,£,etc.,) for that the web config is updated in locally but in site I can not modifiy the web config file and I get the following error

We store backup archives in subfolders of a folder on one of the server's external USB drive. I would like to have an ASP.NET app read the contents of this folder so the manager can view the backup files to confirm backups are working and optionally delete these backup files when an old drive is reconnected so it can be used for the next weeks backups.
This backup folder is oubviously outside the server's webroot. Is there some way I can grant authority so the ASP.Net app can access this folder for this purpose? I would be using VS Web Express, so can't create any signed packages and such.

i have a web application that when i deploy it at a local computer with windows xp apnet_wp needs about 100-140mb of ram. when i deploy it to the webserver it is being reset by the administrator because the ram needed exceeds 250mb.i have noticed that at the local pc there is only one instance of aspnet_wp for all the connected users. On the other hand at the web server there are different instances all over 100mb.1) is there a programmaticaly way to reduse the aspnet_wp.2) does 140mb of ram is extremely big amount of ram for a medium web application?3) is it possible to to configure the web server to run only one instance of aspnet_wp for all connected issues?

I have an ASP.NET 3.5 app that collects data from a handful of external pages, parses the relevant bits and displays them in a table. Total data retrieved is 3-4MB and the resulting page is about 1MB. I am using synchronous WebRequest GetResponse for the retrieval, but the same problem existed using an asynchronous BeginGetResponse/EndGetResponse process.
There is no database access, no session storage, but an in-memory list of about 100 objects/1MB of data, plus a good amount of AJAX (AjaxControlToolkit). This issue appears on the very first run of the app, even if I have restarted IIS.
The issue:
When I run the app on my dev computer, the maximum commit charge is about 1.5GB. The biggest user, measured by Task Manager's VM Size, is WebDev.WebServer.exe (600MB). The app runs perfectly.
When I run it on my rent-a-server (IIS 7.5, 1GB RAM), the maximum commit charge is over 3.8GB. The biggest user is w3wp.exe at 2.7GB. IIS grinds to a halt and spits out a timed-out error page.
Given my limited server budget and the hope of having multiple simultaneous users, I'm kind of in a panic.
I'd like to write and read TCP Streams directly without any modifications by ASP or IIS. Is this possible?
Edit: Goal is to provide communication between a program and a server. Data exchange between them is less then 25 bytes per connection (in default case). So Headers will cause more traffic then the real data. I need to use ASP.Net because the owner of the server will not let me execute my programs.
