I came across a strange behavior with this property. I had a winform with 2 buttons "button1" and "close". In the button1_clicked event I had the following code. I did not put any code in the for loop
int len=ConfigurationManager.AppSettings.Count;
I've set an AppSetting key for my root directory in my web.config file and now I'm going back through my site and changing all link and resources to use this key. Then If the domain ever changes I can just change one line of code and not worry about links breaking. I'm not quite sure however how to use this when I register my header and footer user controls.
View 2 RepliesI am maintaining some Asp.net code and need some help figuring something out. Basically I have a C# statememt that reads as follows
String Em = System.ConfigurationManager.AppSettings.Get("EmailAddress")
So something tells me it is trying to read an email address. I looked in the web.config file and I don't see the string "EmailAdress" defined in the <appsettings> tags or anywhere else. Could I be looking in the wrong web.config file? Or where is system.ConfigurationManager.AppSettngs looking for the definition of the email address?
I am using MS Test to test one of my controller's actions. This method uses the ConfigurationManger to read appSettigns from the web.config. For some reason ConfigurationMangager is not able to find the appsettings.In NUNIT I would just make sure to add a copy of the webconfig file to the test project so that it is available when running in that context. However this is not working for me.
View 1 Repliesi did not realize that: i have a web.config in a separate class library and i was reading the web.config appsetting from different web applicaiton.
i am using VS2010 target framework 3.5
i dont know what is wrong here but i am getting null when i try to get
ConfigurationManager.AppSettings["StoreId"];
string _storeid = GetStoreId;
public static string GetStoreId
{
get
{
return ConfigurationManager.AppSettings["StoreId"];
}
}
<appSettings>
<add key="StoreId" value="123" />
</appSettings>
I am retrieving value from webconfig file.
PriceCode = ConfigurationManager.AppSettings[d.PriceCode].ToString() == "" ? "XXXX" : ConfigurationManager.AppSettings[d.PriceCode].ToString(),
if the value is found its fine, but if the value is not found in webconfig file an exception is thrown... why is that?
I am facing an amazing problem in ASP.NET. I have a website with many sub directories. The sub directories have aspx and aspx.cs files but do not contain web.config files. I am using the web.config file of the parent directory for storing config items for the respective code files in sub directories. But when i m trying to read the web.config using ConfigurationManager.AppSettings[] with absolutely the correct keys, there's no value being returned. Most amazing fact is, this same code works fine in dev enviroment but not in staging.
View 1 RepliesI have a VS2010 Web Application that uses the AjaxControlToolkit. I am able to build the Debug configuration. When I build the release configuration I get the following error message: Error 89 Could not load file or assembly 'file:///S:My CodeLibrariesACTMay 2010AjaxControlToolkit.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) S:My CodeEZFishingEZFishingEZFishingSGEN EZFishing
The location of the file is correct, and I just downloaded and unzipped there the Ajax CT. I have always built this app correctly before upgrading to VS2010 and ACT May 2010.
i have stored settings in the AppSettings section of the web.config file.
I'm trying to access these settings via System.Configuration.ConfigurationSettings.AppSettings, but the AppSettingsCollection is empty. So I can't access this settings.
The strange thing is that this is working on my development machine, but is failing on the production machine. Previous versions of the web application have also worked on the production machine. I'm not aware of any modifications that could couse this.
I have also tried using ConfigurationManager and WebConfigurationManager without success.
I am creating a Console Application and in its code I need to Publish a MVC 3 P1 Application in Release mode.
Just like I do when, in VS2010, I right click the project, click Publish and set the folder to which it should be published.
How can I do this?
Basically I am trying to create a Console Application that publishes an MVC Application and copies some other folders to a Release Folder.
My requirement is to check whether my application is in debug mode or release mode in DLL class.
View 6 RepliesI've got some question about two ways to save settings in the web.config.
Appsettings:
Look in web.config
<appSettings>
<add key="key1" value="value1"/>
<add key="key2" value="value2"/>
</appSettings>
Usage in code-behind:
ConfigurationManager.AppSettings["key1"];
ApplicationSettings/ Properties (autogenerated by using the 'properties'-tab in the project)
Look in web.config
<applicationSettings>
<Projectname.Properties.Settings>
<setting name="Testenvironment" serializeAs="String">
<value>True</value>
</setting>
</Projectname.Properties.Settings>
</applicationSettings>
Usage:
Properties.Settings.Default.Testenvironment
So, what the difference between these two storage possibilities of settings in the web.config? As far as I can see, a downside of the appSettings is that you have modify the web.config yourself and the appSettings are not strong tiped, where as the applicationSettings are. Both are replaceable with in a web deployment project.As far as I am concerned, there is no use for appSettings. Am I missing something here? Which is the historically seen older one?
Is there a way to get load information on Application Server? How much memory or CPU is being used at a given point? I want to either 1. Limit users to use specific functionality of ASP.NET 3.5 application or 2. Deny users from accessing the application saying "Server is busy at the moment"

multiple groups of users interacts using browser. in each group, users will interact with some data(objects). the data(objects) are loaded from database. during the interaction, users needs quick and synchronized view of the same data(object), so they must be save in the memory. data(objects) will change during the interaction, but only the final result of this interaction need to be saved back into DB.
My Current Solution
load data(object) into global.asax the manipulate. but for this solution, i got few questions.
how can i make sure the web application have ONLY ONE instance?(configure in iis-->application pool?) because web application would restart by itself, as a result, all data in the application state will lose. how can i avoid application restart by it self rather than managed? in the iis application pool setting, i can set the recycle time, is it guaranteed that no application restart will happen during this time? or is there and event that might trigger something(before application restart) so i can save the current application status and load them back again?
I have an ASP.net application with c# which uses MS SQL server 2005. I find that the cpu usage of my server reaches 100% when ever i run the application. I was told that i may have memory leak in my application. How can i trace is there are any memory leaks in my application? Note: I am not the programmer of this application. But i have the complete source code as i am doing maintenance and enhancements on this application.

I'm trying to determine the memory used by my ASP.NET MVC application. My host imposes a 100mb application pool memory restriction. However, from my tests, an empty ASP.NET MVC application uses 30mb memory so I have absolutely no hope with an application that actually does something.
I can't find any benchmarks on what a "standard" MVC app should be using (I assume MS have someb somewhere??).
My application is not that special. I use StructureMap for DI and EF Code First. The model is equivelant to that of a blog. If I completely remove my data access code then my memory usage drops to around 40mb (of course in this state its pretty useless).
Bit of a weird title, but here's the deal. For a web site I'm working on, we have the need to generate quasi-3D images on the fly. Basically, it's for an art site, and we have the need to show a 3D representation of a Canvas given a 2D image (jpg). (See here for some context.) The approach we're taking is to leverage the WPF 3D API and create a Viewport3D in code, add a bunch of points to it with the correct dimensions, and then apply the textures from the original jpg appropriately. While testing it, I was testing it the whole time in a sandbox environment, and in the built in Cassini web server in Visual Studio. While trying to migrate it over to the actual code repository and testing it there, it stopped working. The image that's pumped out is the correct size, but is completely blank. It's totally black. After hours of banging my head against the wall, I figured out that it's an IIS issue. I created a simple sample app to demonstrate the issue (doesn't add images though it just paints all sides green), however since most of the code is largely irrelevant to the question, I won't put it here, rather I'll post a link to it:
[URL]
If you do download it and want to run it, in the code behind of Default.aspx you'll see this:
protected void buttonClick(object sender, EventArgs e)
{
var path = @"C: estoutputoutput.png";
IISvsCassini.WpfImageCreator.CreateWPFImage(path);
}
Feel free to change that path to whatever, and make sure that the correct permissions are in place as it'll try to save a file there. If you try that sample in Visual Studio with Cassini, it'll work fine, and you should have a new file called "output.png" which has a green 3D cube. If you try it in IIS, you'll get a blank image. A few points: Before anyone asks, yes, I gave all the proper folders the correct permission issues. I also do the actual 3D generation and image saving on a separate thread with the Apartment state set to STA. know this is a bit of an unusual case of fusing WPF and ASP.Net, but by some chance, Is there some setting in IIS that I need to change? Is there some limitation to the WPF API that won't allow it to run out of IIS?
My web application is of large size and its performnacne is very slow,
now i want to check the memory leaks, are there any third party tools or built in add in in VS 2010 ,

how can i detect memory leaks

I've tried adding reference for ConfigurationManager but it still does not work, what do I do?
Running an ASP.NET application in its own app pool on Windows Server 08 / IIS 7.
Server keeps hitting 97% memory usage and sticking there, trying to work out if that is our application's fault.
My main question is, does all of the memory used by an application get displayed as the working set for the w3wp.exe process associated to it? Our application (according to IIS7 and the worker process in task manager) is using less then 350mb. I want to know if it is possible for our application to be using 5GB of memory but only showing 350mb for the process?
I'd like to describe strange issue I've noticed while analyzing my asp.net application in production and ask for some advice or opinion on the following matter.Application usually runs with some 80-90 MB of memory footprint. This seems stable since no memory leaks have been detected so far - no slight increase in memory usage over time. Yet, problem occurs when application pool recycles (I'm using shared hosting and judging by logs it occurs either when app is idle for 20 mins or every ~30 hours - something like that). The issue is that used memory almost doubles for some period on recycle - it goes to some 160-170 MBs without any explanation. This is confusing, since it is common claim that recycling should purge the memory and all other resources - at least I get it that way. System holds this amount of memory for some 7-8 hours and then memory usage drops to it's usual level of 90-100 MB, again, with no apparent reason (at least not know to me).
View 1 Repliesmy web applications app pool configuration is
PeriodicRestartMemory : 512000
PeriodicRestartPrivateMemory : 196608
although the virtual memory limit is higher than private memory, app pool is recycled with virtual memory limits exceeded errors in the event log (instead of private memory).
what is the reason for this? how could it exceed virtual memory limits before exceeding private memory limits? it seems that systems other allocations in virtual memory cause limits exceeded before applications private allocations exceed the limits, but what are those allocations of the system? or what is the root cause of this.
Pardon if this is more serverfault vs. stackoverflow. It seems to be on the border.
We have an application that caches a large amount of product data for an e-commerce application using ASP.NET caching. This is a dictionary object with 65K elements, and our calculations put the object's size at ~10GB. Problem:
The amount of memory the object consumes seems to be far in excess of our 10GB calculation. BIGGEST CONCERN: We can't seem to use over 60% of the 32GB in the server.
What we've tried so far:
In machine.config/system.web (sf doesn't allow the tags, pardon the formatting):
processModel autoConfig="true" memoryLimit="80"
In web.config/system.web/caching/cache (sf doesn't allow the tags, pardon the formatting):
privateBytesLimit = "20000000000" (and 0, the default of course)
percentagePhysicalMemoryUsedLimit = "90"
Environment:
Windows 2008R2 x64
32GB RAM
IIS7
Nothing seems to allow us to exceed the 60% value.
See screenshot of taskman.
