I couldnt find any where else on this forum for C# so I just posted here because Im using Visual Basic C# 2008 Express. Im making my first game and Ive come across this error: The name 'UpdateInput' does not exist in the current context.

When 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)

When using ASP we can reference HttpContext.Current from anywhere in the code to get at the current http context.
I want to do something similar using HttpListener, so that I can access GET/POST data etc from anywhere in my code. Can I reference some global object for this, or do I need to explicitly pass the current HttpListenerContext object all through my code?
I got this message because of a long process: ContextSwitchDeadlock was detected

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. I've poked around on the internet and on a forum, someone suggested to use application.doevents(). I did that and the messaged goes away. In an earlier thread a member wrote that using application.doevents rarely was used appropriately. Is my situation a proper usage of application.doevents or is there something else I should be doing?
Do I have to sign my VB.NET applications? I'm getting an error: SignTool reported an error 'Keyset does not exist' But have no interest in signing anything as the project is small and will only be used internally to my department. I could create a temporary key. But why would I want to?
View 4 RepliesI am trying to run my projects and i come across this visual studio error.Is this because of the .suo?? "Method does not exist" in vb.net
View 4 RepliesI am trying to install the My.Blogs sample. I am running VS2005 Pro on WindowsXP Pro SP2. The template installation fails with the error message:
Installation stopped because the directory for the ProjectType value did not exist. The project type is invalid for your installation of Visual Studio.
Is My.Blogs a beta2 only thing? I am running release VS2005. Are there manual instructions for installing this via file copy?
Also: the error message suffers from poor design. Of more use would be something along the lines of "The project type 'inserttype' is invalid for your installation of Visual Studio, which I detect is: 'insert detected VS version'.
We have a program called MasterPack (old school dos style) which we generate quotes from and this picks up a quote.doc in a folder called Quotes in the C drive which is a mail merge document and populates all the fields. There are 3 files in this Quotes folder,quote.doc, QUOTE.txt, and quote.hedRecently one of my employees had his PC upgraded to a new unit and it came with Office 2007 (previously used 2003) and now we have this run time errorSo what happens now is we go through the steps and then it gets to the "Opening this document will run the following SQL command" and click Yes to continue, the SQL msg comes up again (that never happened before) so we click yes again. It thinks then opens the word doc and populates the fields but then the run time error window pops up and if we choose "End" the merge fields are not populated and return to the merge field names EG. <<CustName>> etc etc.

I have been able to use my.resources perfectly, no problems at all. all of a sudden, i try to use resource (i have done EVERYTHING EXACTLY the same as the way i have been using for the last 1 and a half years) and i get an error saying the file does not exist. its there, i only need to type my.resources.s and it already selected the resource i want. it says the file doesn't exist. why? also, the resource is called settings.dat. could that be the problem, don't think it is. i even tried a picture, but it still says the file doesn't exist.
It says: Could not find file 'C:Users[username removed]DocumentsVisual Studio 2008ProjectsdiskSaverdiskSaverinDebugSystem.Byte[]'.
I worked out a way around it (i worked out how to use my.settings in stead), but i haven't worked out why my.resources won't work.

View 2 RepliesI'm currently trying to create a NEWID() function in my DataContext in LINQ using the solution here, however, when adding the partial class to my DataContext.vb or a separate DataContextPartial.vb, I get the error System.Data.Function is not available in this context because it is 'Friend'.
I've come across this when accessing data types before and that was in easy fix of setting it to Public, but I'm not sure where the properties for function could be or how to change them.The code I have is converted to VB.NET from the C# in the linked answer above:

View 1 RepliesWhile I've previously many years of relational databases and procedural languages, I'm stumbling with Visual Basic. In this problem, the simple situation is that I have two files, parent and child. The primary key of the parent file (Area file) is linked by a relation to one of the two fields that makes up the primary key in the child file (Project file) (unique key is formed from 'area' and 'project'). I have the default table adapters created on both files. I have created two maintenance forms showing one each of the two files in datagrid view format.I can create some records in the Parent (Area) file, but when I try to create a record in the child (Project) file, using one of the valid key values from the Area file, I get the 'ForeignKeyConstraint [relation name] requires the child key values [actual value] to exist in the parent table' which I'm absolutely definitely sure it does.
I haven't done any actual coding for those two maintenance forms, just dragged-and-dropped the files from the data sources screen onto separate forms so it creates the controls itself. But I can't work out, if it already knows the data does exist because I can load it back in to the Area maintence form, why it can't check itself to find out the record does exist. Why does it think the record from the parent record doesn't exist? It does exactly the same thing, whether or not the database is in access or SQL Server Express. I have all the latest updates.
I use this code to move to the next record. but when I move last and then I click movenext I get the "No current record error" but in the code I specified "If Not dbs.EOF Then". How can adjust the code so that I dont get this error
If dbs.RecordCount > 0 Then
If Not dbs.EOF Then
dbs.MoveNext()
