Why it is giving this error? Why it is not locating CheckUserName() function that I have added in myPage.aspx.cs file which is it admin's folder?Is it the path issue that I have given in JSON? or its due to something else !!!

View 2 RepliesError Occurring When Using Wcf To Run Query - Memory Gates Checking Failed Because Of The Free Memory
May 21, 2010I 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.
Error: Attempted To Read Or Write Protected Memory. This Is Often An Indication That Other Memory Is Corrupt?
Oct 11, 2010I 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.

Attempted To Read Or Write Protected Memory. This Is Often An Indication That Other Memory?
Jan 26, 2011I 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?
DataSource Controls :: Memory Leak - Server Will Crash - Log A Ton Of SQL Errors Stating That It Is "out Of Memory"
Jul 27, 2010I 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?
ANTS Memory Profiler - Which Memory Should Be Looking At?
Aug 24, 2010I 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.

Jun 15, 2010Is there any way to check a web service's availability and get an alert whenever it is down?
I am supporting a very critical application and it went down few times because the webservice that it is supposed to be using was not accessible to it. So is there a way in which I could set up some monitoring and poll the web service periodically to check if it is available or not.
If calling the web service is the only way to check, I have a method in the web service which is supposed to return true.. How do I write code(windows app/web app/windows service/anything) so that it calls this method every 5 mins and sends me an email.
What would be the best way to setup the periodic polling, and how do I do it?
C# - Availability Of Methods On The Basis Of Constructor?
Jan 19, 2011I have a Class called Repository for accessing (Read/Write to and from) Database.The projects that require access to the database create an object of Repository and pass the connection string as a constructor parameter for the repository to work for that particular project.
I have few methods in the Repository that i want to be available only if certain connection strings are passed. I don't want them to be available if some different connection string is passed.Is there any way I can accomplish that?I have never used method header technique, if yes, how can i use it? if no, please let me know if there is any other way to achieve my goal.
Determining If User Is Log In Or Out?
Mar 9, 2011I am currently developing a site for my OJT.I have created a login form for my site now I got confused on what to do with this one. I need to identify if the user has been log-in or log-out As the user inputted the exact username and password it will go to this line of codes in which will identity if the user has bees signout or not.
HttpCookie cookie = new HttpCookie("isLog");
cookie.Value = "1";
DateTime dtNow = DateTime.Now;
TimeSpan tsMinute = new TimeSpan(1, 1, 0, 0);
cookie.Expires = dtNow + tsMinute;
Response.Cookies.Add(cookie);
Response.Redirect("manageService.aspx");
And I have this function to determine if the user has been log-in or log-out.
protected Boolean isLog()
{
//String strCookieName = Request.QueryString["cookie"].ToString();
//Grab the cookie
HttpCookie cookie = Request.Cookies["isLog"];
String tmp = cookie.Value.ToString();
return (tmp != null);
}
Now, my problem here is that even though I inputted the correct username and password after reloading the page it will still asked for the user name and password(sends me to the login page). I already set a value for the "isLog" cookie but still it return a wrong info.

View 3 RepliesWCF / ASMX :: File Protection / Availability In A Web Service?
Oct 5, 2010I wrote a small web service (asmx) to write stuff to a file on the server. It works fine when run in the VS2008 test container. But when I run it under IIS on a remote machine, I get:
System.IO.DirectoryNotFoundException: Could not find a part of the path 'y:grahammiscprops.txt'.
'y' is a mounted drive on both the test and remote machines. The path really does exist. It works on the test machine; not remotely. So:
Is it the fact that 'y' is a mounted drive causing it to fail remotely? or Is it the fact the the path lies outside of the web application directory structure? Is there something I should put in web.config??; or
Is something else the problem? I would have thought that the service running on the server could do anything it wanted! It's not denying me access to the file; it's saying it can't find it??!!

View 2 RepliesWeb Forms :: Use The MasterPage To Check The Availability Of A Session?
Jan 30, 2011I have a web site using master page and login page. I use the MasterPage to check the availability of a session. I'm coding with VB + MS Access database.I believe something is wrong with my master page and I can't figure it out. In the code behind of the MasterPage, I try to check the user session is available. If so, the user is still logged and get access to all the menu. If no session is available, it means the user is logged out and few menu as shown. Here is the code
[Code]....
Please note that my Login.aspx page is also base on the same MasterPage. On the Login.aspx.vb, if the user credential are correct, I did this:
[Code]....
So my logic is this: when the web site is launched MasterPage + Default.aspx load. So Sesson("MyLink") is empty. If the user's credential are correct, I create the session so the it can be available for MasterPage.My default menu isMenuPublic1, MenuPublic2, MenuPublic3When a user logged in, I add to the MenuPublic some reserved menu like below.MenuPublic1, MenuPublic2, MenuPublic3, Menu_Users1, Menu_Users2, Menu_Users3I'm testing my application on two different web hosting server: aspspider.com and somee.com. In the local, everything works perfectly fine.My problem is that on aspspider.com if a user logged in and then click on any MenuPublic, the application does not let him show information from Menu_Users. It's wrongly sending him to the login.aspx but still show his profil on the masterpage and the "welcome username" with beside the Logout link. It seems like the user is still connected but cannot have access to users pages.On the other server (somee.com), even if the user logged in successfully, I still have "welcome guess" with beside the Login link. I also have the user's profil information with all the links. If a user click on any MenuPublic, he can still see all the Menu_Users. But if he clicks on any Menu_Users, the application redirect him to the login.aspx; but still displaying all the information as if he is logged.The package deployed on both server is the same; except the connection string.FYI, I have Global.asa in the package but I don't use it. The web.config has plenty of stuff that came when I first start the project. The only thing I added is the connection string.
