Why would database drivers work in the development environment of VB.Net and not once the project is built and installed on the same pc? I've tried the MS ODBC Oracle driver. I've tried various ODBC datasources. All work when I am in the development environment but none once I build and install. No matter whether the configuration is Debug or Release. This is the only project having this problem. I have other apps (VB.Net) that access the same database (Oracle 9.2) with no problem.The environment variables are the same during both types of runs. The error messages vary depending upon the driver being used.

I am using LINQ to SQL and a third party SDK that supports distributed transactions. When I realize that a pending update will be updating both SQL records and records in the third party SDK, I am creating a TransactionScope with a 0 (presumably infinite) timeout (although I've also tried 12 hours as a timespan parameter). Then I use GetDtcTransaction on the ambient transaction (created by transactionscope) to get a DTC transaction to link to the third party SDK. Things work nicely for about 10 minutes, but after 10 minutes, the transaction disappears and an error occurs. How do I determine why the transaction is disappearing. I suspect it's a timeout because it regularly occurs after 10 minutes even though slightly varying degrees of work have been done at that point. But I'm at a loss about how to determine what terminated the transaction, why, and how to extend its life.

I'm wondering, is there a way to update databases of a windows application that is distributed on several computers all at the same time? is it done by using sql server? because I'm developing an examination system that will be distributed on several computers for students to take exams and I'm just wondering if an admin updates a questions database will the changes be applied to all other computers as well or should it be done manually? sorry if I sound stupid but I can't seem to understand this part of my work, I was thinking about switching to a web app since it seems easier, but again this data updating issue is giving me hard time. by the way I might link the application to an internal network, will this have anything to do with updating the databases?

We've recently moved to Team System and now a remote team needs access to our source. However, they use a different IP address to access the Team System server, and whenever they try to open a project, they are prompted to check out and change the project. It seems to be the 'SccAuxPath' property which is the problem.

We have a couple of applications at work that need a reference to the license server set in the User Variables under the Enviroment Variables on the windows xp client machines(system properties, Advanced, Enviroment Variables). The problem is that both applications needs a reference to the same variable name and you can't have two with the same name. What i intend to do is to create a simple windows application with a button for each application that deletes the variable item present, adds a new variable item with the value needed for that application to be able to run and then run the application itself. This is just a temporary fix until we get a more permanent solution. The 'GetEnvironmentVariable' class in vb is not able to add or delete a item, maybe the WIN32 API could do the job.

I was trying to learn how to do openGL within a VB .NET environment and it seems that the Tao framework or OpenTK is recommended with OpenTK having a higher recommendation so that is what I chose to try using. Since I am brand new to this, I am trying to just draw a simple box, triangle, or anything really so that I can understand it all before making more complex things. I have been unsuccessful at this so far so I will list in order what I have done so far and hopefully someone here can help me correct it or provide a new example just so I can draw a simple shape.
1) I installed OpenTK using opentk-2010-10-06.exe
2) In a new project I added the references to OpenTK.dll and OpenTK.Compatibility.dll
3) I added the control (opentk.glcontrol.dll)
4) I added the actual control to my form.Using some examples online I added the rest:
5) I wrote my references in:
Imports OpenTK
Imports OpenTK.GLControl
Imports OpenTK.Platform

The above results in no display?

I use Environment.NewLine, my colleagues use vbCrLf.When I'm doing a code review for them I want something that I can point to to say "use Environment.NewLine instead of vbCrLf"
Or, am I just peeing in the wind, and it doesn't really matter ?

I am trying to change the way my aspx pages load when I double-click on them in my development environment. I wish for the markup to show instead of the design. So, I go into "Tools" -> "Options" -> "HTML Designer" and make my changes. However, I have to do this every time I get into VS. How do I make those changes stick?

Ok, I am needing to capture the username of the user who is logged into a third party software (similar to citrix) which then will launch compiled vb.net applications from the 'Cloud'. If the user logs into their windows active directory machine as Smith123, and then logs into this third party software as SmithS, and launch a compiled program which runs on the remote server, and executes a button that displays the environment .username results, what will return? Smith123 or SmithS?
I am trying to figure this out, and I would just create a program and try it out myself but going through all of the hoops, bells and whistles of where I work just to get a simple compiled piece of code up on the server can be a pain sometimes..

Environnent.NewLine seems to be resolving to two spaces " " (as are vbCrLf and ControlChars.CrLF). Using StringBuilder, AppendLine is doing the same.I've been racking my brain and searching the Internet trying to figure out why this the way it is, but am coming up empty.

I am looking to read a text line from an ini file which may contain strings like %systemRoot% or other environment variables. I was able to write small function to parse such strings as long as it appears only once in the path. for example my fuction can parse %systemroot%system32 and return c:winntsystem32.however if the string contains %systemroot%\%username% i am not sure how to handle that.
