ExecuteReader Requires An Open And Available Connection. ...current State Is Connecting
Apr 21, 2010Using VS 2005 and SQL Express 2005. This WinForm application runs fine on 5 out of 6 stand alone computers that is it installed on. The 6th computer is slightly older running XP sp2.As I understand it, using DbDataAdapter will perform the open, close and dispose functions for you. Therefore, Pooling should not be an issue. I am thinking that the default 15 second time out setting may be the cause?? There is some MultiThreading that will also use DbDataAdapters in the same manner but only 3-4 would be firing at the same time.The connection string is Data Source=(local)DataBase;Initial Catalog=Code;Integrated Security=True The command which throws the exception is If CodeDataAdapter.Fill(CodeDataSet.CodeTable) > 0 Then...So I am thinking that adding Connect Timeout = 60 to the connection string even though the 15 second default seems like a lifetime. Could this 15 seconds be eaten up if some other process or application takes over?

in a Drag & Drop event i have to check if the Cursor is the Double Arrow Icon to resize the Cell now i use
if Cursor.Current.Handle = 65553 Or Cursor.Current.Handle = 65555 Then

sure, i can add the other 2 Handles.. but thats not really a proper solution.
Connection's Current State Is Closed - Connect To Sql Server And Display A Record
Jun 21, 2010I am a ASP Classic Programmer, professionally for a little over a year, I have developed some rather nice sites, including the one in my signature (Still a work in progress).
I have been forced to use ASP.NET (VB) for a FileUpload control, as it offers a self controlled way of creating Thumbnails, without the use of 3rd party controls, which is great, as my hosting server does not allow for 3rd party installs on their servers.
So.
The code below is what I have so far for connecting to the database and displaying a record is the "cookie" exist on the users computer.
Unfortunantly, this is not working, and to be honest with you, their is not a whole lot of resources available to show how to do this correctly.
So I am stuck with a lot of post and hoping that someone can actually assist me with this and tell me what I am doing wrong and maybe correct my code.
I am getting an error about the "Connection is closed"
If you want to re-write my code, I prefer something simple and basic, as the only thing that I am doing to checking rather the user is logged in, and if so, display a record from the database. I am NOT in the need for the DataGrid, so please do not suggest it, as I am only needing to check this one thing.
I would like to also add, that I have successfully contect to my database with the FileUpload control and save file names of the images uploaded, so I know that my connection string is done properly> But, for some reason the "SELECT" statement is causing a HUGE issue. (It was easier to insert, than to select, I am not use to that)

View 2 RepliesMonitor The Current Position Of The Mouse Cursor?
Apr 21, 2009I'm trying to create a hook to monitor the current position of the mouse cursor. Nothing important, I just need to count some pixels during interface design and wanted to learn how to create a hook, so I decided to go for a hard way instead of a sane way.
I've found example code which declares the following function:
<DllImport("User32.dll", CharSet:=CharSet.Auto, _
CallingConvention:=CallingConvention.StdCall)> _
Public Overloads Shared Function SetWindowsHookEx _
[Code].....
But Appdomain.GetCurrentThreadID generates the warning: "'Public Shared Function GetCurrentThreadId() As Integer' is obsolete: 'AppDomain.GetCurrentThreadId has been deprecated because it does not provide a stable Id when managed threads are running on fibers (aka lightweight threads). To get a stable identifier for a managed thread, use the ManagedThreadId property on Thread."
I've tried using ManagedThreadID, but that doesn't work. The thread ID returned seems to be the logical thread ID of the thread, as it runs in the .net runtime, rather than the Win32 thread identifier.
Calling the function ith AppDomain.GetCurrentThreadID works, but I really would like to have a "stable identifier" for my thread.
Can someone explain to me whether it is possible to use ManagedThreadID in this context (I assume not) and, if not, the things I need to avoid in order to stop the AppDomain.CurrentThreadID from becoming "unstable"?

View 5 RepliesVS 2010 - On Load (Startup) Default State?
Jan 14, 2012I haven't used VB in decades and I'm restarting with what I thought would be a simple program. I have two fields on a little form, both of which display a date (dd/mm/yyyy). Field1 is an entry field except on load where is contains a date calculated from field2 (which is 'now' upon application load). Field1 is 'now' + 10 days. This is the default state.
Once loaded (with the data described above), the user can input only in field1. Field2, an inactive field used only for display, is field1 - 10 days. After 15 seconds, fields 1 and 2 revert to their default states as described in the first paragraph. I'm getting all messed up with the 'on load' state. I'll start playing with the timer once I get the initial stuff done.
