I came across this Switching from VB.NET to C#?I would be moving from C# to VB.Net. To be more precise, I would be moving from C# 3.0 to VB 10.0 (.Net 3.5 to .Net 4.0). I am initially planning to use a C# to VB converter to cope up with the syntax.

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.

The programme is called mydata and Colin is my User name. Anybody got any idea what is wrong and how to correct it. I have tried to run it in Visual Basic 2010 Express and get the same error.

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

View 2 RepliesI am working on a website web site where each user has a culture setting to allow control of resources displayed. The main page has two views, one the log on screen, the second the main menu.
When first loaded the page displays with the culture settings of the previous user (if any). If I then log on as a user with a different culture setting the view changes to the main menu without changing the culture. Go to another page and the user's correct culture settings are picked up, go back to the main menu, uses the correct culture etc.
This is logical but is there a way (without redesigning the site to have a separate log in page and main menu) to reset the culture to the new user's when switching view?

View 1 RepliesI need my VBA Macro to locate text throughout a document and move it. The information that needs moved can easily be detected by the font colors. For example:

I have a richtextbox, with random values in each line:
a1,a2,a3
b1,b2,b3
and so on.
This textbox stores the values in a jagged array after lostfocus. What i am trying to do, is for the user to have the ability to 'switch' values in each line if he wishes to do so. Each switched element becomes the first, and the first goes where the old value was. So it's basically a 'swap'. For example:Line1: a1,a2,a3 --> user highlights "a3", right clicks and a contextmenustrip appears with the option 'switch', once he clicks a3 goes where a1 was and a1 goes to a3. So the new Line1 would be: a3,a2,a1. After that if he switches a2, new Line1 would be: a2,a3,a1 Once the switch is done in the array, redisplaying the data in the RTB is not a prob.
In Netbeans you can have multiple projects open at once. You just click the side bar, click the project, and can jump between them. It's very convenient for when I want to look at some code I wrote on a previous project and apply it to my current one
