Apr 5, 2011I have 16 student machines who can not access the windows live login during the school hours due to filtering restrictions. They need to register Visual Basic 2008 Express Edition within 30 days or the product becomes useless. The registration process wants them to login to access the keys. Is there an alternative way to obtain the keys as a group, rather than one-by-one?Everything I've found redirects to the 2010 version, but the 2008 version works with our textbooks.

View 4 RepliesError: The CLR Has Been Unable To Transition From COM Context 0x4cefd8 To COM Context 0x4cf148 For 60 Seconds
Aug 20, 2009When bulk renaming files (14000 of them) i get this error: The CLR has been unable to transition from COM context 0x4cefd8 to COM context 0x4cf148 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.
My code is as follows:
Private Sub frmTest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim asd As List(Of String) = FileIO.FileSystem.GetFiles("D:Music").ToList
Dim rs As New ADODB.RecordSet("SELECT * FROM Songs", My.Settings.Files_Database__Connection)

Convert A Two-table Exists Query From SQL To Linq Using Dynamic Fields In The Subquery?
Jun 7, 2011I'm trying to query old Access database tables and compare them with SQL Server tables.They often don't have primary keys, or they have extra fields that had some purpose in the nineties, etc., or the new tables have new fields, etc.I need to find records - based on a set of fields specified at runtime - that are in one table but not another.So, I do this kind of query all the time in SQL, when I'm comparing data in different tables:
dim fields_i_care_about as string = "field1, field2, field3"
'This kind of thing gets set by a caller, can be any number of fields, depends on the
'table
dim s as string= ""
[code]....
It tells me it can't convert a Boolean - Is there any way to do this without Linq expressions? They seem far more complex than what I'm trying to do here, and they take a lot of code, and also I can't seem to find examples of Expressions where we're comparing two fields in a subquery.Is there a simpler way? I know I could do the usual EXISTS query using JOIN or IN - in this case I don't need the query to be super fast or anything. And I don't need to use a DataTable or DataSet - I can put the data in some other kind of object.
What Is The Data Context Property
Aug 12, 2010I was reading the MSDN manual, I was reading about the about the binding.source property. I got a little confused because the manual started taling about the data context property. My question is what is the data context property ? Whenever I look through the properties of an object ( either textbox, datagrid etc ) I can't see this property listed anywhere.Could it be that the version of visual basic that I'm using ( which is Vb 2008 express ) doesn't include this property.

View 6 RepliesUse Partials And Stored Procs On The Same Data Context?
Oct 25, 2011I'm working with system using Linq-2-SQL as its data layer, but which uses stored procedures to do the actual CRUD operations - the stored procs are configured against the CRUD methods for the data class in the model designer.These are all working just fine.Now we want to use partial classes to extend the functionality of our data classes to apply validation, and hold parsed versions of some of the database properties.
However when I create a partial class for one of the data classes, the datacontext stops using the methods configured against the dataclass and defaults to its own operations. This happens even if the partial is empty other than the just the class declaration.
I would guess that this might be because the method signature for the insert method stops tying up to what the datacontext is looking for, but I can't see any overrides available to help fix it.Is there a way around this so that I can use Partials and Stored Procs on the same data context?

dim classname = split(exp,",")(0)
dim propertyname=split(exp,",")(1)
dim value= classname.propertyname
End Function

Getting The Dynamic Code Execution?
Aug 23, 2010i'm building a basic server program that I want to recieve commands and execute them sent from a client program and I'm using my home network to test it out. I've got no problem with the communication between the client and server programs and have used a simple Send Text function to communicate to the server program which simply brings up whatever text was sent in a message box.
I've decided that constantly updating the program and transferring the new EXE file just doesnt work as I have to keep starting and stopping the server program to do that just to update the list of commands it recieves. So say for example I've got a button on my client program that tells the server to open the cd-rom draw on that computer, it sends this in the form of simple text openCDdraw" and when the server recieves this, it pops open the cd draw and so on and so on... but I thought a better way of doing this may be to say have the commands listed in a SQL database and when the server recieves a message it searches through the database to find the correct command and executes the code associated with the command.
Now I can retrieve the information fine in to a string variable ("Dim a as string, a = dr.getvalue(3)") but where do I go for there? This is the problem see. My apologies if I've gone a bit long winded on this one but thought it necessary to explain what I'm doing. I've heard of dynamic code execution but when I tried a project I found on the internet it had been coded in C# and I don't know any C nor do I want to as I'm a VB veteran and have updated myself with the way of .NET now so am not going to start all over again with learning C. Does anyone know of an easier way of doing this? Static code is so easy to do because it is typed straight into the coding sections and I had already thought about creating loads of subs/functions to execute each command but again that involves updating the EXE file every time so there must be a better and easier way of doing it.
Can I also just point out that this little project i'm working on is not for a TROJAN or whatever that old NETBUS program used to be called, it is simply so I know how to do it and can use it for other things that I'm working on and through. Also I'd just like to know how to retrieve and execute code from a database or text file.

Error - System.Data.Function Is Not Available In This Context Because It Is 'Friend'

Oct 10, 2011I've done this many time before, but for some reason I can't get it to work this time.I'm trying to get a ContextMenuStrip associated with a DataGridView. I've defined each to the form and in the properties of the DataGridView I've set the ContextMenuStrip property equal to my ContextMenuStrip name (cmsDictionary), defined the onClick event code, but when I run nothing happens.
The program was originally code with a dynamically added context menu but it was popping up all over the place and I wanted to remove that and just let the grid manage it.
