Forms Data Controls :: How To Share Class With Not Enough Memory
Dec 22, 2010
I am getting some memory issues, not entirely sure but does anyone think this could be the issue.On the itemdatabound event the following code runs, and it calls a shared class method Return Image which resizes the original image. Could the coding be the issue for the memory problem. There are about 10 or so items.
If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
Dim ImgProfile As Image

We have about 70 sites on our server that use same application (with different Application Pools) and they use for example a shared skin file. So is there a way to load this file to memory and share for all applications? what I mean is to sharing cache in multiple websites to decrease pressure on server.

I had two seperated projects that used the same database, similar methods, etc. So i've created a new solution and added those two projects.I've created an C# Class Library project and i've writed there all the methods from the other two. I've also created an edmx file for DAL layer. I've added the reference of the C# Class Library projects to others two but now i'm having an problem.When i try to connect to database i get the error message: "The connection specified wasn't founded in aplication, doesn't destinate to be used with the EntityClient or isnt't valid" (i've translated this from Portuguese, so it's 100% correct).

I have a static class I'm using as my data layer in my website. In this class, I have string arrays that store queried information that I can access later. Here's the part of my class and the method in question:
public static class data_layer
{
ivate static string[] items;
private static string[] description;
//will return description for an item id. if no item id is found, null is returned
public static string getDesc(string key)

I am using DevExpress Gridview basically, and hit out of memory exception whenever I keep refresh page that contains huge data. I reported to DevExpress team and they claimed it is ASP.NET gridview issue.
Therefore, I create a simple project, a girdview to sqlDataSource. Run the page and press F5 to refresh. I use ANTS profiler to check if any object instance is keep increasing but never been disposed. I found that, memory does happen in this simple project, as what DevExpress team claimed.[Code]....

I'm a bit of an ASP.NET newbie and I am creating a data table in memory and binding this to a gridview control. The code is as follows:
Dim DstBasket As New DataSet, TblBasket As New DataTable
With TblBasket
.Columns.Add("BskPrdCd", System.Type.GetType("System.String"))
.Columns.Add("BskPrdDesc", System.Type.GetType("System.String"))
.Columns.Add("BskQty", System.Type.GetType("System.Int16"))
.LoadDataRow(Split("12345,Test product 1,1", ","), True)
.LoadDataRow(Split("122,Test product 2,2", ","), True)
.LoadDataRow(Split("123A,Test product 3,5", ","), True)
.LoadDataRow(Split("44,Test product 4,1", ","), True)
End With
DstBasket.Tables.Add(TblBasket)
With LfnGridView("GdvBasket")
.DataSource = DstBasket
.DataBind()
End With
The data displays in the gridview control fine with both edit & delete options but when I attempt to delete, it has no effect. How do I force removal of the relevant row from both gridview and table? Most of the documentation I have unearthed shows how to achieve this when connected to a SQL table which is clearly not the case here.

I 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?

I am building an asp.net application, using II6 on windows server 2003 (vps hosting).
I am confronted with an error I didn't receive on my development machine (windows 7, iis 7.5, 64 bit).
When my wcf service tries launching my query running against a local sql server this is the error I receive:
Memory gates checking failed because the free memory (43732992 bytes) is less than 5% of total memory. As a result, the service will not be available for incoming requests. To resolve this, either reduce the load on the machine or adjust the value of minFreeMemoryPercentageToActivateService on the serviceHostingEnvironment config element.

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?

im about to wirte an app that is an extension from the main application that is hosted on the IIS. My application is going to work as a child app (main app as parent) working in main application pool. User will be redirected from the menu to main app to my website. And here is my problem. I would like to pass informations like user login, login state etc. I cant do it via Query String - that wouldnt be safe. I thought I could pass it via Session state, since the SessionID is the same both sides but I cannot retrives parameters on my website(theyre null).

I have a memory issue on my websites and am trying to get to the bottom of it. I have downloaded the 14 day trial of ANTS Memory Profiler and have been playing with it to get a grip of what it's telling me. In the memory options on the timeline, I can see Bytes in All Heaps and Private Bytes etc but I am not sure which ones I should be focusing on to see where the memory spikes and doesn't go back down.I am profiling a ASP.NET website using ASP.NET 2.0.

I have an ASP.NET MVC application that attempts to read a file in using a filestream and File.OpenRead().
When the path to the file is a share on the same workgroup, and I give access to NETWORK SERVICE for the share, this works perfectly as desired.
However, when the path to the share is a UNC path to a remote share within the LAN, with read permissions open for "Everyone", the "File.OpenRead()" method throws an exception saying "Could not find a part of the path".
In my test cases I'm debugging locally with the ASP.NET MVC app being given a UNC path to the computer that it's actually running on. It's a share on my C drive, being "Shared" with permissions to "Everyone" for read access.
Is there something in IIS that needs to be configured? If I try to impersonate, in this context, the impersonation doesn't matter because NETWORK SERVICE was the user trying to access the files when it worked for a share in the same workgroup.

I populate a DetailsView from an ObjectDataSource that is coded in a class - meaning that the ods Select, Update, Insert and Delete are class methods. The selected record is set to come from a GridView.SelectedValue.
My problem is that when the page loads the code crashes. I am pretty sure I know why: the DetailsView is pulling from a class object and instead of using the existing class object it instansiates a new one which is empty.
Here is the details view code:
[Code]....
Here is the odsDetailsView_1:
[Code]....
As you can see from the code the odsDetailsView gets it's information from a class object "Match". The detailsview is not controlled by any code behind.
