It happens frequently when I try to copy & paste code inside VS 2010 with following message:
insufficient available memory to meet the expected demands of an operation at this time, possibly due to virtual address space fragmentation. Please try later.
and I check the memory usage with taskmanager on my computer. It is fine.
In order fix it, I need to close VS 2010 and restart again.
all of a sudden i cant copy or paste code snippets in my code. what can it be? neither i can copy the folder from the wwwroot folder.
View 1 RepliesIf I have the following in an ASP.NET Web Form:
<asp:TextBox runat="server" ID="tbxUser"/>
and I copy and paste that line in the same page, I usually get the following:
<asp:TextBox runat="server" ID="TextBox1"/>
Obviously, nobody is going to name their controls in that way (if you don't want to name a textbox, simply don't asign an ID to it), and it's not nice having to change the ids of pasted controls. The same happens if I copy a control without an explicit ID, VS simply generates one for me. Is there any way of preventing VS from autogenerating IDs when I copy-paste ASP.NET code?
I have a site that was created with VWD2005. I tried to open the solution with VS 2008. This prompted me to convert it which I did. Now when I look at the project in the Solution Explorer in VS 2008, I see all of the files but they are now with in a folder named "2" that's within a folder named "back up". I also see another folder with in the solution that's named _UpgradeReport_Files.
The files for my project that are with in the folder "2" that is with in the folder "back up" are actually in the back up folder for my project in the Visual Studio 2005 folder with in My Documents. I assume this is because I chose the "create back" up option when doing the conversion. I don't understand why these files and this project aren't in the project directory with in the VS2008 folder with in My Documents.
I want all of my files for this project to be in the projects folder with in the Visual Studio 2008 folder in My documents, the same as if I had created this project in Visual Studio 2008 originally. But the conversion doesn't seem to have done this. Instead I seem to be using a solution/project that references the original files with in the back up folder as mentioned above.
Can I just create a new project in VS 2008 and paste these files into it? Will this work? I'm not sure if it will because the original one was created in VWD 2005 which I think uses the .net framework 2.0. My Visual Studio 2008 uses version 3.5 Sp1 of the .NET framework.
I just started using VWD 2010 and I used Copy Web to upload the site to the server. However, whenever I try to upload a new version of a file that I've already uploaded, the upload fails, with this error in the log (as an example):
Copy from 'C:UsersLouDocumentsVisual Studio 2010WebSitesgenusus10 ools' to 'ftp://69.67.214.24/web/tools' started at 10/6/2010 4:00:33 PM.

View 3 RepliesI have a memory leak somewhere that I cant find. Every few days my server will crash, and just before that I log a ton of SQL errors stating that it is "out of memory".
I cant find it anywhere, all of my connections are being disposed like so:
[Code]....
Then I call the connection from my pages like so:[Code]....
That is all pretty straight forward. The connection is disposed because it is implementing the USING clause. I am opening the connection in my connection manager class, and not where it is being utilized?Or, could the problem be in the below method I am using to populate a SqlDataReader:[Code]....
Now, at first it appears as though this could be the problem because the Connection isn't part of a USING clause, however doesn't the 'Data.CommandBehavior.CloseConnection' pretty much do the same thing. This makes sure that the connection is closed when the reader is closed, right? Here is how I call that above reader from my login page code behind:[Code]....
So the DataReader will get closed even without the .Close() because it is in the USING, and the connection should get closed because I specified it in the ExecuteReader paramters right?

On http://msdn.microsoft.com/en-us/library/w070t6ka(v=VS.100).aspx there is an example on how to do impersonation with .net 4.0. We have used this example in a class that inherits IDisposable for ease of use. However, when we use this class in a asp.net web application, we notice a slight but steady increase of Pool Paged Bytes in performance monitor. After a week, the application crashes.
I've tried different implementations of the impersonation-class, using http://msdn.microsoft.com/en-us/library/w070t6ka(v=VS.90).aspx and http://support.microsoft.com/kb/306158 as reference, but they all show the same leak.
Where does this leak come from? Is there a problem with the windows api? We are running Windows 2008 R2.
This is our current version of the impersonation class:
public class Impersonator : IDisposable
{
public Impersonator(string username, string domain, string password)
{
if (!ImpersonateValidUser(username, domain, password))[code]....
And this is the performance monitor graph of two webservers using different versions of the class:
When we disable the class, and use global impersonation via web.config, those lines are completely flat.
Update,I have made a test-application that successfully reproduce the problem. It can be downloaded here:
http://rapidshare.com/files/447325211/ImpersonationTest.zip
The result over 18 hours looks like this:
We got a problem in one of our ASP.net apps, the mscorwks.dll is using a lot of memory. where to start looking for the memory leak ?

View 1 Replies I'm writing an MVC app and want to have a central DataBase factory class to provide all my DB connections, something like this:-
[Code]....obviously I'll have to instanciate this every time I need to use it, so I was thinking of making it a static class:-
[Code].... so that instead of my controller code saying
[Code].... I can just say
but would this cause a memory leak? I'm sure I remember reading somewhere that if a static class creates objects that persist beyond it's methods and return those (esp things like DB connection objects) these won't get garbaged collected when the calling method is disposed of as they were created/referenced outside the scope of that calling (controller action) method and so will hang around in memory?
var tableObject = DatabaseFactory.GetDatabaseTable();
List<DbRecord> records = tableObject.Table.ToList();
I created a site which fills an UpdatePanel with dynamically created buttons when clicking on an other button. Now every time I click the button the used memory increases. I already tried the workaround from http://www.crockford.com/javascript/memory/leak.html to remove old eventhandlers before updating the UpdatePanel. But the used memory still increase. Is there a problem with my code or is there an other workaround?
Here is the code of a sample aspx site which shows the problem: [Code]....

I have an .Net Framework #4.0 application that makes a large number of web requests using the WebRequest/WebResponse classes , as i see it has memory leak (or maybe i am doing something wrong)I Wrote some small simple application that demonstrates this:
class Program
{
public static void Main(string[] args)[code]...
The only one solution i came up with is use GC.Collect() (unmarked in example) , All the object are disposed , all streams are closed , am I missing something ?I found something but i don't understand the reason , if i minimize Console the memory usage decreases and looks O.K , what can be the reason for that is there a problem with Conosole or WinForm .

I've created a small class library to asynchronously call a WebService(Fire and Forget. I don't need the result).In a Windows Form application, the XXXAsync() method works fine. But, in a Web Application, the process is locked until the XXXCompleted event is fire.My problem is: I tried to create a Delegate and use the Begin/EndInvoke to call the XXXAsync() method. It worked fine, but, the w3wp process seems to be consuming a huge amount of memory. I'm calling the EndInvoke method properly. Invoking the GC.Collect did not free any memory
