Switching Between SQL 2008 And SQL 2000 In VB
Jun 18, 2009
I have written a VB 2008 Standard Edition program using a SQL 2008 Epress database in my development environment. When I point my program to the production SQL 2000 database it blows up. With the following error:
---------------------------
Microsoft Visual Studio
---------------------------
GentranDataSet.Document_tb.Fill,GetData () could not be previewed.
The text, ntext, and image data types cannot be compared or sorted, except when using IS NULL or LIKE operator.
---------------------------
OK Help
---------------------------
The tables are "exactly" the same in the two databases... I think.
I have done some reading and wonder if this could be a unicode and non-unicode issue. Is 2000 non-unicode and 2008 unicode?
Can I "refresh" my data enviroment without having to re-create all my data objects in my VB code?

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

Most of my project started out using Access databases, but now I want to swap them out for the SQL versions. One example would be this:
DEMOGRAPHICSTableAdapter.FillByCount(EyeBaseDataSet.DEMOGRAPHICS)
SPat = EyeBaseDataSetSQL.DEMOGRAPHICS.Patient_NumberColumn.Ordinal
'TODO: This line of code loads data into the 'EyeBaseDataSet.History' table. You can move,

I will start off here by asking the question. How do I make the data from a database be bound to my project? I keep trying to add a new data source so that I can drag and drop things to my form, but I am unable to. I follow the steps, choosing an OLE DB, the file's location (D:Data Connected Applicationsfile name) The conecting string looks like: Provider=Microsoft.ACE.OLEDB.12.0;Data Source="D:Data Connected ApplicationsItem_Database_A.accdb". I choose the objects that I want (In this case, the entire tables option) and then it returns a message to me stating that: An error occurred while creating the new data source: Could not get information for 'WindowsApplication1.Item_Database_A.accdbDataSet3'

The coding that I have a problem with might make people think that I am creating some malware. So the project I am doing is associated with iTunes. iTunes allows people to have one library. There is another way, but it is very confusing to some people, and very unreliable. So my project is that I will allow people to have multiple iTunes libraries on one computer. So the problem is this. In order to have an option to choose your library, I gotta make sure that iTunes is not running.
So this is the script:
Private Sub CheckAndCloseiTunes()
retry:
'Custom class that includes the function to safely close iTunes
Dim Processes As Process() = Process.GetProcessesByName("iTunes")
[CODE]...
So when I use the Threading.Thread.Sleep(2000) code, the form becomes unresponsive.

I work for a somewhat large company.There are about 160 Windows XP Pro users. We are still using Microsoft Office 2000 for the most part.We have upgraded some users to Office 2003. We are not using Microsoft Exchange.I have to export every users' Outlook 2000 or Outlook 2003 Contacts into an Excel or CSV file every 6 months as a way of backing the Outlook Address Contacts.Currently I am doing this by physically going to every pc and manually exporting the contacts.This is a large pain.I am trying to find out if I can use or create a Visual Basic 2008 Express program or script that will export the contacts from Outlook and save it as an Excel or CSV file.The name of the file should be the same as the computers net name.It should be saved in the same location, on the network, each time.I am new to programming and new to VB 2008 Express.I do not know or have any code to start with.

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.

In my project, I want the abiliity to switch between forms without closing them. What is the best way to do this? I have a "Login Splash Form" that you sign into, and then a Main Menu Form opens in Full Screen. I want this form always to stay open with the ability to open up other forms from this main menu screen as needed.

I 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.

Having had to replace my old computer, one can virtually only get 64 bit Win7 in UK.All my old Visual Studio 2008 + other components installed OK but when I tried to build and run a prgramme that still runs happily on the old machine, I get the following error message
System.TypeInitializationException was unhandled
Message=The type initializer for 'mydata.Colin' threw an exception.
Source=mydata
TypeName=mydata.Colin
StackTrace:
[Code]...
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.
Hopefully VB2012 will have Gigs of error messages that mere mortals can understand!

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

I'm starting to play around some with VB2008.
In VB6, I would write something like this:
rs.open("SELECT * FROM Contacts", cn1)
strFirstName = rs!FirstName
In VB2008, line 2 does not work. How do get to the fields in the recordset?

I am currently writing a program and I have all the windows in three languages. Is there any way of quickly changing through the languages? I mean, I can do it manually but the list has like 500+ languages and I was wondering if there was any keyboard shortcut to switch between the used languages, or any way to put a buttom on the toolbar.

I'm writing a flash cards program to help myself and others study. When the user presses the "New Card" button, I've been able to make it create the new card and jump to edit it, but the dataset/binding source/table adapter is not switching with it, so when you deselect the text box, it switches back to whatever was selected before the new card was made.[code]

How do I set up a VB.NET program so it will run on W2K ? I understand I can only use .Net 2.0 or older. Is there an easy way to limit which .net version is used/referenced ? (I have .Net 3.5 on my XP development computer) Updating target computers to XP, Vista, Windows 7 is NOT an option.
