I just learned some basics of multi threading in VB.net recently as I came across processing a large List of records and inserting them into SQL database one by one.
I have code look like this:
Private Sub btnLoadNow_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoadNow.Click
Dim autoLoad1 As New Thread(AddressOf AutoLoad)
autoLoad1.Start()
[CODE]...
Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?

I was working on an app that calls a batch file to do some simple tasks and found out this machine has some issues when trying to run them. really weird! so i did some testing and here are my resultsthis is a little strange to me and i can't think of why this is happening... let's say i have a simple bat file called test.bat these are the contents
@echo off
echo testing...
pause
When i go to run this bat, this is the output: C:>â– @ 'â– @' is not recognized as an internal or external command, operable program or batch file. It seems every bat i make on this machine is being preempted by the block character which renders bat files useless...

I have created tool which performs batch processing on files that are selected. The sub routine I have defined in the code, now I want to implement a way through which I can select actions that I want to perform and then perform the actions. For example the list has multiple actions, like Open, Close, SaveAs, Resize, Color Correct etc. I should be able to select what all I want to do on each file and then perform this actions. Someone suggested me using delegates for this, but I cant use that since all my functions have different parameters. Ither option I had is to use a nested IfElse or Switch to determine which action is selected and call function according to it, but thats to heavy I think, is there any optimized a better way to do this.???

I would like to know how to select multiple records from a gridview, (ie checkboxes in itemtemplate) and process SQL statements on the records. So in short, its basically selecting records from a grid view by ticking the check boxes, and clicking a process button which then proceeds to execute the SQL statements corresponding to the records selected.[URL]..

2008 Array Processing and Sequential File Processing
View 14 Replies
May 19, 2011
Im a college student and this is my first programming class, i am having extremely diffcult time with arrays and sequential file processing. Im not asking for the whole program, just something to get me started and hints along as i progress with it. Please help me get started on my program, its due in 2 days.
Here are the requirements....
1. The program must input any number of individual�s last and first names using two separate textboxes.
2. The array of names must be sorted by the last name using a bubble sort. You must code the sort.
3. The program must be able to recall the names from the file and add to the existing list of names so that more names can be added to, sorted, and written back to the file in sorted order.
4. Sort in ascending order: A to Z
5. All names must be displayed in a listbox in sorted order when the user wishes to see them.
6. In the listbox the last and first names must be separated by a comma and a space. Example: Smith, Mary
7. The user must be able to search for a name in the array, using the binary search algorithm. You must code the search.
8. Do not use module-level variables. Instead you may choose to use Static.
9. The program must be designed using Visual Basic 2008

I have this piece of code wich works perfectly when inserting records into one table using records from another table. My question is that now i need to create another table by using records from 3 other tables (tables are related). Can i use aliases on the column names, like on Oracle SqlPlus? How will be the syntax of the 'INSERT INTO SQL statement?

At 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.

I haven't seen a related thread (yet)I have a VB windows application that uses a datagrid to display a text column and a checkbox column. Only one row in the display can have a checkbox entry = true. If a checkbox is selected, the app is to search the rows and all other checkbox entries are to be set to false.My event handler is: Private Sub dgMember_CellContentClick(ByVal sender As System.Object, ByVal e As ystem.Windows.Forms.DataGridViewCellEventArgs) Handles dgMember.CellValueChangedI first had to have this handler code check a flag and exit if true (when initializing the display) because it was called for each row during initialization.

I have a form with several buttons on it.When a button is pressed,it will execute some remoting proxy method on the server. There is some delay in the process before there is a result returned from server .Currently,I tried to disable the button in the _Click event, hoping that a 2nd, 3rd and the following clicks would not be registered.Unfortunately, those input from the mouse clicks were queued by Windows.
So once the _Click event has finished running, it will immediately get executed again due to the earlier clicking.I tried to create a form (Notice) to display some status message, hoping that clicks won't be registered on the button. Despite setting the form to maximize and on top of the caller form, the clicks still get registered.Then I thought of using .ShowDialog(). Unfortunately, it halts the processing until I close the form. So I did something more complicated by passing in the method into Notice form, so that it would execute the _Click method via an address pointer.Unfortunately, after all these coding. The buttons still get registered with the mouse clicks.So now, is there any way to overcome this clicking queue that Windows registered?

I'm thinking of making use of online technology to do some validation and processing for my program but I'm unsure of its feasibility. I need to create a program whereby the client can retrieve the data/settings from website say http:[url].... .Another example would be allowing the program to run until end of December by making use of online time service to check the date so that user can't change any settings from their computer.
While discussing about retrieving the data either through html static site or webservices, another thing I'm concern is transmitting the data from client side to my side.I wonder what is the best and free way to do that? As I'm thinking of using a free smtp gmail to transmit data but I'm worried about the security issue as credentials would be stored inside the program and also firewall might block data from sending out. Another choice would be sending a POST request, but I do not have any server or is there any free server that allows user to post some small bytes of data?
