VS 2008 How To Let A Class Do Mathatical Side
Aug 18, 2009
Hey everyone - I am working on a project and having a hard time getting my head around serparating the business logic from the rest - In the course I am doing we covered it breifly - but I am a tad cunfussed as how to let a class do the mathatical side of things for me - What I want it for my main form to have no formulas in it (which is the essence of seperating the business logic as far as I am aware) - From the code below I want the main form to grab the data entered in the textbox and for that to be sent to the class and then the approprite value to be returned.[code]As much as this is related to the course I am doing - it is not work to be submitted for grading - It is just an extra exercises for my own learning and satisfaction.

I know this defeats the purpose of client side vs. server side (refer to title of this thread). What I would love to do is build my own custom progress indicator on the client showing how far a server side code has progressed. I figure if I could only get a JavaScript to fire and render a value of some control at pre-defined intervals while the server is working I could make it happen - but alas I'm beginning to believe that this is impossible. Below is some code that performs three 2 sec loops. At the end of each I want to change the visible value of a control on the browser. [Code]

I have a basic asp.net web page. I have a menu bar divided into 3 columns. Each column displays an xml file. However instead of showing them side by side it displays them one on top of each other. i think it might be to do with my css?

<div class="menubar">
<div class="menuleft">

Using the following script:
$("#some_button").click(function() {
var changed = [];
[CODE]...
I need to send back the id, the old value from _1 and the new value from _0 back to the server. What is the best way to format this data so I can easily extract the data from the server side so I can easily email someone for example to let them know which textboxes have changed, what the old values were, and what the new values are
At the serverside level, I am using .NET-3.5 (VB). I know how to send the data bacl. and how to email the data, I just wanted to know how to best format the data at clientside before sending it back. I could have upto 50 sets of id, old, and new values to send back. Sorry for not making that clear earlier.
Example:
How can I modify the script above to generate this?
[
{
"id": "name_0",
"new": "text",

Here are my two grids -- they are ExtJs grids however we wrap the declarations in vb.net code:
Dim VehicleOptionsGrid As New Framework.WebControls.Grids.Grid
With VehicleOptionsGrid
.ID = "VehicleOptionsGrid"
.Title = "Vehicle Options"
[code]....
Using javascript, is there anyway I can add a bottom scroll bar to these grids? Doesn't seem like we have a wrapped command to do it...

I currently have a parent Listview and its child Listview displaying in the centre column of an HTML page that consists of three columns left, centre and right. And all looks very good. However I would like to display the child list view in the right column beside the parent list view.
To do this it seems I must somehow generate from the code behind page a new row in the table every time the parent Listview displays a record of its data and then some column HTML so the first child list view will appear in the right hand column.

I'm trying to, from a client-side piece, call off to a server-side piece. I need to do this synchronously. On my server-side code, though, I'm calling off to another piece of code, which I want to have a maximum of, say, 10 seconds to return a value. If I don't have a response within 10 seconds, I want to force my own server piece to set my result equal to 0, and return to the client.
Here's what I have on my server-side code so far:
Public Function GetWebResult(ByVal inputParameter As Object) As WebReturnObject Implements IWebInterface.GetWebResult
Dim result As New WebReturnObject
Dim webItem As WebItem = Nothing
[CODE]...
I realize this code is not functional. The problem is that I'm unsure how I would go about getting back into GetWebResult to set the appropriate return values before it is sent back to the client.

I am struckup with a problem from last two days. I am creating a web application using VB.NET, Ajax & RAD Controls. When user clicks on a button I want to open a RAD Window and show the list of ledgers available to the user, so that he can select one from the list. And to open that window I have to call a java script function from client side, which is already achieved using the below code.

I add an option to a select with jQuery. When I save with an asp button, I don't see the changes on the server side in the click event.
And the HTML is all correct after I add the option.
Is it a coding problem or I don't understand something?
$(selectCourant)
.append($("<option></option>")
.attr("value",$(dropdown).val())
.text($(dropdown + " option:selected").text()));

Basicly I have a program that retrieves data and parses it, which is fine, so it starts from:11:981.8 which equals to November 981.8 now what I have done is split the "November" and the "981.8" into 2 different arrays, with other similar data, now what I need to be able to do, is sort the array in either Ascending or Descending order, however keeping in tact, the November and 981.8 side by side in a list box.
My current code is:
Private Sub sortData(ByVal strYear As String, ByVal strSort As String)
lbDispData.Items.Clear()
Dim strData As String = My.Settings.usage2011
Dim arrRawData() As String
[Code]...
EDIT: Just to mention, there are many more values, not just November and 981.8, there would be for example December and 128.1, January and 191.1, etc.

I am starting a butterfly program and having an issue and really just barely have it started and would like to get some helpfeedback on how to do this. The following is the instructions and I will make a second post on what code I have so far...The butterfly is going to be moving from side to side in a slightly upward assent when the animation starts. You need to build a set of controls that allow the user to control whether the butterfly ascends (up) or descends (down) and also allows the direction of the butterfly to change (left or right). The best way to implement this feature is through the use of keystrokes that when pressed act to control the direction of the butterfly. Whether you implement this feature through keystrokes or controls, make sure that the feature is communicated to the user.
Butterflies fly by opening and closing their wings. So it is expected that the butterfly will alternate between opened and closed as it wings its way across the form. If the butterfly is moving right, make certain the butterfly graphic displayed shows the butterfly as moving toward the right. If the butterfly is moving to the left, make certain the butterfly graphic displayed shows the butterfly as moving toward the left.
If the butterfly reaches the top of the form in its assent, it should wrap around to the bottom of the form. If the butterfly reaches the bottom of the form in its descent, it should wrap around to the top of the form. If the butterfly reaches the left edge of the form, it should begin flying toward the right side of the form. If the butterfly reaches the right edge of the form, it should begin flying toward the left side of the form. If the user changes the direction of the butterfly, insure that the correct graphics are used in relation to the direction of the butterfly and that the butterfly moves in the indicated direction. Please note that when the butterfly reaches the edge of the form, the butterfly must change direction regardless of any user input.

Ultimately, what I want to accomplish is an AJAX-based messaging system. I already have a database table for messages, and an ASPX to add new messages (and declare old messages no longer relevant).
The current messaging system simply polls the server every 15 seconds, and re-pulls the current message set.
What I am looking to do is: On $(document).ready(), register an ajax callback function that listens for a server-side event (e.g., MessagesUpdated) On table insert/update, fire MessagesUpdated server-side.
This way, whenever the table is updated (or new records added), any clients listening know that new data is available and can re-poll the server then.
Ideally, I'd also like to make the new data available as an event argument (to minimize re-polling the db).
I can find references to something like this in other languages, but I cannot find any actual code examples to get me started.
Assuming this is possible to do via .Net, can anyone help get me started on this?
I'm using the 2.0 Framework. Also while I added a VB.Net tag, I can read C# reasonably well, so please feel free to post in either language.

I've been working on a way to check a user's hardware for performance reasons and have been using WMI to find almost all the information I need. One thing absent is the FSB of the processor (it's not in the Win32_Processor Class as far as I can tell).
Does anyone know of a way I could go about to find this using an API, Memcopy or something?

I have a 'property management class' that contains several functions and properties. I have several other classes that use the 'management class' as a property to derive the value of several of its other properties.Is there a way for me to reference the outer class from the 'management class' functions without having to pass it as a parameter? I ask because several different classes can have this 'management class' as a property and am having a hard time typing the parameter.

i have a class call it clsFamily this class contains properties that make up a family object. This class works fine with no issues. Now i need a new class (called MyAccount) which contains 3 properties, an ID a user name and a clsFamily object. I have declared both classes as Friend from within my globals Module and define the clsFamily as family, however when i try to put this type within my 2nd class i get an error "Type 'family' is not defined" what am i doing wrong? i know i could get it to work fine by adding the ID and User Name properties to the clsFamily object but i need to define this as a new type of object as the ID and User name are not normally part of this class.
