Concurrency - SqlConnection Already Open In Case Of Concurrent Access To Same Page

Dec 29, 2010

I have a strange problem in my ASP.Net 3.5 application. When multiple users try to access the same page (which has some long running methods), the application crashes at a point where it tries to open a connection to the database (a static method inside a static class). It appears that the connection is already open. However, this does not happen when there is only one user using the application. What I cannot understand is that how do actions of one user affect the other in a web application?

I double checked that all my open connections are being closed after performing their operation by appending a line of text to a text file whenever a connection is opened or closed. The number of opened and closed connections was equal. Also, the connections are opened and closed from one place only, where the close method is inside a Finally() block.

Vb.net - Close A Sqlconnection In .net?

May 17, 2010

i would like to know if there's something wrong in this asp.net code:

mydatareader = mycmd.executeReader()
if myDataReader.HasRow then
// Do something
end if
myConnection.Close()

If i avoid to call a "MyDataReader.Close()" does the connection close anyway ? I ask this because i'm assuming that if call a "MyConn.Close" it automatically close the associated datareader... or am i wrong ?

Visual Studio 2008 Compile / Trying To Open An Existing App?

Mar 31, 2010

I am trying to open an existing asp.net app. on my local machine with VS2008. The app. resides in a folder on the Windows 2003 Server. The app. runs on our intranet. Recently, a change was made to the app. directly by opening one of the files in the solution and adding maybe a couple of lines of c# code and saved back. Of course this would not make a difference as its not been re-compiled.

I copied the whole folder where the app. resides on the server to my desktop and then tried to open the solution with VS2008, it came up with a prompt saying the app was written using a previous version of Visual Studio and needed to be converted to VS2008 format, I followed the intructions, but it failed saying something like "...failed to make a backup etc", it wouldn't open the solution.I have successfully open other apps this way but this one particular one would not just open. All I want to do is to use VS2008 to recompile and publish back to the server. I have tried using VS2005, it just says the app. was created by a newer version of the application...

I think the app was built sometime btw 2004 - 2008. Also, if it is relevant, the folder where the app. resides on the server has a globe icon, don't know if its an IIS thingIs there any other way to compile this .net app. without using VS2008,

There was an error downloading metadata from the address.verify that you have entered a valid address. I didn't write any code in ISALESservice.svc AND ITARGETservice.svc . I have written in SALESservice.svc.cs AND TARGETservice.svc.cs files.Is this causing error? But for SALESservice.svc it is working. I didn't add any code in web.config file.

VS 2008 Open Input Type File On Image Click

Nov 13, 2010

I am trying to streamline the look of my site and I was wondering if there was a way to use the onclick of an image to open up a <input type="file.../>? I want the input to be invisible so it doesn't add clutter to the interface. Here is ultimatly the flow I would ideally have... Image click -> Javascript calls input open. User clicks "open" in the dialog, Input calls some Javascript that calls the click event of the inviable "upload" button. Boom. User clicks image, selects a new one, and I have it automatically on my server without the need for two more buttons... Anyone know if these types of events/functions exists and if so what they are called and how to capture them? Or should I stop making this over complicated and use the method that I know works?

Installation :: Unable To Open MVC Project In Visual Studio 2008

Apr 20, 2010

I started working on an Asp.net MVC website using Visual Web Developer Express 2008 a while ago. Just recently, I managed to get my hands on a copy of Visual Studio 2008 Professional (through DreamSpark ). I installed the Service Pack, and also the MVC2 files for Visual Studio.

However, now I can't open my project anymore. When I try to open the solution in Visual Studio, it tells me that the project type is not supported. Does this mean that I have to resort to using VWD Express again? Is there perhaps some way that I can edit the project file so that it will load and compile correctly?

Note: I installed MVC2 through the Web Platform Installer, and it says that it installed successfully. However, I notice that MVC references in my unit-test project don't seem to be resolved either - is this perhaps because MVC2 isn't actually installed properly?
