How I convert my app to run with old .NET Frameworks? My app need to be compatible with more number of computers as possible without need to install the new version of framework
I have created an exe file by compling on vb. However finding that not all systems like it and .net framework & isnt as compatible as you first think. I have create an application which doesnt use "imports" to reference anything. I compiled it in .net framework 2.0. It didnt work on XP machine which had .net Framework 4.0 got runtime error. Is there anyway making the compliled .exe available for all frameworks or am I going to have to create an .exe for each .net framework to encompass all versions?? Does it have to use .net framework at all depending on the application?
View 3 RepliesWhat's a good way to define what the Framework's are?Basically I'm looking for a good way to give a brief overview of what the .Net Frameworks are and why an average person should have them installed.
View 3 RepliesIn Visual Studio i can select the target .net framework version, which for example defaults to 3.5. Now when i build my application with this setting, i guess it wont work on computers with .net framework 3.5 not installed, right?But lets say i choose .net framework 2.0 as target .net framework. Will my application work on computers that have .net 3.0 or .net 3.5 framework installed, but not 2.0?In other words: Is the .net framwork always backward-compatible?
View 1 RepliesI know this question has been asked before, but none of the existing SO questions provide an adequate answer for my specific case.
I'm the lone developer working on a project mostly during free time. I'm approaching 100 classes so far, and I'm starting to realize that testing that many classes is becoming daunting. Especially as I go back and add in operator overloads for =, <>, CType, and Not; implement IComparable(Of T), IEquatable(Of T), IEqualityComparer(Of T); and overriding base methods like Equals and GetHashCode.
My current testing method has been to randomly scribble out some Debug.Print code for a specific class/method on a dummy form behind a single button, run the project, click the button, and make sure the Debug window has my expected value. But this is both tedious and starting to become a time waster.
What I know that I need to do is for each and every class, draft up a set of tests specific to that class to test its functionality. So I go and look at testing frameworks like NUnit, Gallio/MbUnit, etc. But I really don't see the value in them. It so far seems that I could just write a dedicated test class for each implemented class, wrapped in #If DEBUG/#End If blocks, and link those to a bunch of buttons on a large form to run my tests.
But that could take weeks at my current rate. So I ask SO for their opinion on how to approach something like this. Am I better off figuring out how to integrate one of these open source testing frameworks into my project? Or should I just write a bunch of testing classes and output their data somewhere?
I use VB Express 2010 and VS 2010, depending on which computer I'm on so I'll need to be able to do testing in both.

View 3 RepliesI have 2 listbox's, same locations/sizes (one behind the other). I have 2 buttons, and they just switch the views between the listbox's by changing their visibility propertyThe problem is listbox1, which gets populated first, displays just fine. No code in the program touches listbox2, except for 1 button that adds items. When switching to listbox2 to see the added items, the items are there (verified by debugging and hovering over the added variable), but the text that is displayed won't update. The text that is displayed is the text from listbox1.

I have an application I wrote that is in VB.NET 2.0. Works great, but I'd like to switch this application to Linq. I use ADO.NET to load XML into a datatable. The XML file has about 90,000 records in it. I then use the Datatable.Select to perform searches against that Datatable. The search control is a free form textbox. So if the user types in terms it searches instantly. Any further terms that are typed in continue to restrict the results. So you can type in Bob, or type in Bob Barker. Or type in Bob Barker Price is Right. The more criteria typed in the more narrowed your result. I bind the results to a gridview.
1) Go to Project Properties --> Advanced Compiler Settings and change the Target framework to 3.5 from 2.0.
2) Add the reference to System.XML.Linq, Add the Imports statement to the classes.
So I'm not sure what the best approach is going forward after that. I assume I use XDocument.Load, then my search subroutine runs against the XDocument. Do I just do the standard Linq query for this sort of repeated search? Like so:
Dim people =
from phonebook in doc.Root.Elements("phonebook")
where phonebook.Element("userid") = "whatever"
select phonebook
