I have the below mentioned code in a seperate class file for establishing connection and carry out DB transactions. I have an issue where multiple connections being opened which sometime exceed the connection pool. When I stepped through the code I found that there are codes which call ConnectDB() in a loop without calling DisconnectDB(). But I expected that the condition OraConn.State = ConnectionState.Closed should handle the situation. Somehow the condition is always satisfied hence openning another set of connection. Can you suggest where am I going wrong and also what best practice can be adopted here?
[Code]...
The connection is again opened in function updData(). While I understand that it has to be closed correctly but keeping tab on every developer is not possible. Hence I want to control it directly from the connection class by using the same connection but the condition If OraConn.State = ConnectionState.
UPDATE I have put the code in UpdateDB under a Using block and removed call to ConnectDB and DisconnectDB from function like InsertData(...). It seems that the issue has been resolved. But I would like to know in case of exception will the connection remain open? and also OraConn is a public variable defined outside Using block so will it be disposed of by the GC?

I'm trying to port an ASP.NET 4.0 data-driven app to a VB Express 2010 Windows Forms desktop app. The ASP.NET 4.0 app uses a SQL Server 2008 Express database and works fine. I can change/add/delete data in the db with the web app, and I can use SQL Server Management Studio to modify the database, but when I try to establish a connection to the same database with the "Add new connection" wizard in VB Express 2010, it tells me that it cannot find the SQL Server Data Provider .The SQL Server provider MUST be installed because otherwise the web app wouldn't work, right ?

how I can Encrypt the data that is requested/sent? I wrote an application that connects to MySQL to INSERT/UPDATE/READ information from/to. The application also connects to a website of mine. I have obfuscated the codes so that people can not simply de-compile it to see my information. However I, or anyone, can simple use Wireshark or Fiddler to see information like...
How can I encrypt that so i can at least feel a bit safer... the attacker can also use replay attack on my website until they get into a user's account...

if anyone had managed to configure BDP as a datasource inside Visual Studio 2008 ? I have added references etc and can query the database at runtime but I seem unable to configure it so I can add it at design time to be able to use LINQ etc, if someone has managed to do this can you let me know how as having to manually check tables etc outside of visual studio is time consuming.

I'm using Visual Studio 2008 on an XP machine. My other machine died so I had to re-install VS on a new machine. Everything worked find until I went to the new machine. Now I keep getting these 2 messages below when I go to build my solution:
Unable to find dependency 'interop.stdole' (signature ='(null)' Version='2.0.0.0') of assembly axinterop.mscomctllib.dll
Unable to find dependency 'interop.stdole' (signature ='(null)' Version='2.0.0.0') of assembly interop.mscomctllib.dll
I tried to remove the references to both .dll's and then re-add them in and that didn't work. I tried removing and re-adding stdole, and that doesn't work either. I tried installing VS on another machine, but I get the same messages there.
The only thing I noticed out of the ordinary is under Detected Dependencies, when I right-click on axinterop.mscomctllib.dll and view the dependecies, I noticed there is a yellow exclamation point in the icon for interop.stdole. I don't see any information regarding that exclamation point however.

I have developed a windows based application using visual studio 2005 called DMS. On the client side, this application runs on asp dot net framework 2.0. We have created its setup file which has to be installed on the client pc. After the installation of the application, some of the users get the error message as:
DMS.exe - .net framework initiation error Unable to find a version of the runtime to run this application
(I have also attached the screen shot of the error message.) Trouble shooting done by me:
a. I had tried the re-install Dot Net Framework 2.0.
b. Scanned the PC for virus attack.
c. Install dot net framework 2.0 first and then the application.
d. Un-install and re-install the whole application.
But none of the solution works. The only thing that works temporarily is un-install the whole application and re-install it. Then it works for a few hours.

I have written an application that calls 'My.Computer.FileSystem.SpecialDirectories.Currentm UserApplicationData'. My application is working fine, but one user has reported an issue that has me stumped. When this property is accessed, the following exception is thrown:
"Unable to find an entry point named 'VerLanguageName' in DLL 'version.dll'". The stack trace says that the exception came from Microsoft.Win32.UnsafeNativeMethods.VerLanguageNam e(Int32 langID, StringBuilder lpBuffer, Int32 nSize)
I don't think the problem is with my code. I suspect that there is something wrong with a system-level component on her computer, particularly with the DLL that is mentioned. Is this DLL part of a specific windows component that could be reinstalled/repaired?
