Split The Arraylist Thumbs Into Parts Of 15 And Call The Function With Thumbs
Apr 29, 2012
In the code below there is a inparameter named thumbs to the function CreatePage. thumbs is an arraylist. My question is if you know if it's possible to split the arraylist thumbs into parts of 15 and call the function with thumbs(1-15), thumbs(16-30), thumbs(31-45) and so on. Until the arraylist is empty.
html.CreatePage(txtTitleTag.Text, txtText.Text, "index", txtDirectory.Text & "", thumbs, txtMetaDesc.Text, txtMetaKeywords.Text, "test.com", "test2.com", BackgroundColor, FontColor)

I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for
Here's my call:
<script type="text/javascript">
function HelloWorld()
{
var yourName = $get('txtYourName').value;

My application reuses the same data returned from the database throughout the application. For example, a list of airport codes retrieved from the dataabase could be used on 5 different forms. In VB6 I placed the information into a Public Array. I'm looking for the best way to load and make available without hitting the database 5 times. After researching I found arraylist might be the way to go. My problem...I'm not sure I'm doing this correctly and not sure how to make the call to get the data out of the list.

I want to create an ExpressionTree where a Func(of Vector, Vector, Vector, Vector, Double, Double, Vektor) should be called. So I use
Expression.Call(Forces(0).Function.Method, {Vec1, Vec2, Vec3, Vec4, Double1, Double2})(Vec1-4, Double1-2 are declared as ParameterExpression and Forces(0).Function as Func(of Vector, Vector, Vector, Vector, Double, Double, Vector). But I get an AgrumentException, because Forces(0).Function.Method has seven Arguments. (System.Runtime.CompilerServices.Closure as seventh argument at Index 0).

How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).
Anyway what I am trying to do in steps:
1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.
The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.
I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.

I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()
takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:
Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)
Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?

Some programs implement command parameters, Like my favourite computer game - Crysis - has them and windows media player has them.But how could i implement them in VB.NET..I want to have a component of my program built as a seperate exe - so it can be an Optional component.But of course the seperate exe, on load, needs data passing to it.So i need something like Process.start("Componentname.exe", "/StartDL <Suchandsuchastring>)/StartDL will need to call a function, and the string that it uses will be given to the function to initiate a download?

I am attempting to inherit an ASP.NET RegularExpressionValidator and add some functionality to it. I inherited the control and added my custom properties. However, I would also like the client-side functionality to call a different JavaScript function.
In order to do that, I will need to supress what is happening in the AddAttributesToRender method because the name of the function is hard-coded there. Here is what comes up in Reflector for the AddAttributesToRender function in RegularExpressionValidator:

Note: I tried to add the expando property before the parent class does to see if the code would check for its existence and skip it, but that just causes an exception.

I'm trying to get split to work.Here is my code
Public Sub CheckUpdate(ByVal FileURL As String)
Dim instance As WebClient = New WebClient
Dim ApplyTo As String = instance.DownloadString(FileURL)
asd = ApplyTo.Split(",")
End Sub
I use it like this
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
NewUpdate.CheckUpdate("version.txt")
Label1.Text = NewUpdate.asd(0)
End Sub
(yeah I know i use it on local txt for now!)So with asd(0) it reads the whole file. If i check asd(1) I get IndexOutOfRange . So how does Split() work?
