I am using query from a SQLite database as the AutocompleteCustomSource for a ComboBox. Also, I want to load data in separate thread. My LoadData method works fine when called directly, but it fails when it is called from the BackgroundWorker thread. When it is called from the background thread, it throws a Specified cast is not valid exception on the csearch.AutoCompleteCustomSource.Add(hh("Taj")) line. Below is my code:
Sub LoadData()
Dim connetionString As String
Dim cnn As SQLiteConnection
[Code].....
what I am trying to accomplish worked with the code in the last thread I posted a while back. I still am using this code, however, I changed the window size to work better and gave it a nicer background for the title screen of my project. Now what I am working on at the moment is making a settings form that has 2 labels. One for "Default" Layout and one for "Plain" layout. When default is at start, the default label is disabled,and when plain layout is clicked, the button is disabled and default button is enabled.Basically, this is a toggle switch for default or plain where if one is enabled, the option for it is disabled and the other is enabled.My problem is that when I switch from Plain back to default, the background Image will not switch back from the plain background color of "control"Here is my code:
Public Class Settings
Private Sub LinkLabel1_LinkClicked(ByVal sender As System.Object, ByVal e As System.Windows.Forms.LinkLabelLinkClickedEventArgs) Handles LinkLabel1.LinkClicked
MiDNiGHT.BackgroundImage = Nothing[code].......
I need a block of code which run a job in background. Suppose the user click on the Submit button, then a job starts in background, in the mean time the user closes that window and run a different job, and the job should keep running.
View 5 RepliesAt the moment, my project has a method do_job(jobid,userid)
This method take a minute or two, and then redirects to another page. This has been rewritten so that it now runs in the background and redirects to another page whilst the thread which do_job is on continues. - This works fine. In a button_click event in a default.aspx page :
Dim d as New do_job_delegate(AddressOf do_job)
d.BeginInvoke(jobid,userid, New AsyncCallback(AddressOf Callback),d)
Response.redirect("results.aspx")
[Code]....
So what i want to happen is - the longest time that do_job takes is the longest time of the longest job (30 seconds), rather than - 30 seconds x number of jobs = time it takes at the moment.
As i'm already using a delegate to detact the process from the ui, can anyone provide any advice/best practice on how i should rearrange my do_job method so that it can handle concurrent tasks to further boost the overall speed.
My application generates some background threads to perform some slow jobs (a cycle of ask for a long process to a server - wait - download the result).

View 2 RepliesI'm writing an application in Visual Basic Express 2008, part of the function being to walk through a folder structure starting from a user specified folder. In my research, I found this thing called a background worker which seemed an appropriate tool to use given the potential size of a target folder structure. I successfully installed the two examples from the library here, and believe I understand the principles involved. Even so, having tried to build this feature into my application, it seems as though it is not working as expected, and, as predicted, debugging a multi-threaded application is a pain in the extremity.
I have this fragment under my "start" button click event -
HomeSource.Enabled = False
HomeCopy.Enabled = False

View 1 RepliesI've created a new form in my program and dragged the windows media player into the form. I have an mp3 in a resources folder within the project. I've set the URL to the name of the mp3. I've looked at tutorials but they make the windows player accessible to the users. I just want the user to be able to hear the music and not be able to change anything regarding the background music.
I want the music to start playing at runtime and continue to loop for now. I will eventually want to switch up the background music depending on which form the user is on. But for now I would be happy just getting a single mp3 to play continuously.
