OK - you're still using VB6 ? This will work, but, as I said, it's really a bad way to go about things. If you're doing hobby stuff, it probably doesn't matter, but I'd be speaking to anyone on my team who wrote code like this.

VB6 *was* easy, in the process, it encouraged really bad habits.
My core recommendation - even if you're just coding for fun, anyone who wants to program, should be able to use google. This site is great, but it's also great to be able to actually find stuff out for yourself.
http://www.google.com.au/search?hl=en&q=vb.net+delegate&meta=[^]
There's plenty of info on the web about delegates. I deliberatly try to answer and give people the keyword that will give them all the info they need, if they can be bothered to look.
If you're going to use VB.NET, you should really forget the VB syntax, just like learning C#, I had to ignore the C++ syntax. It's a new language, and you need to learn it, not try to turn it into the one you used before.
By all means, keep posting questions here. But, do try to do some research first, you'll find things move a lot quicker for you.
Good luck !!

thanks for doing that for me
now i understand the mean of delegate but i still not understand how to use , i m tring to know about it
it will more easy to undertand if someone help me through example than read in webs
|

I don't understand - if I write up an example, it will just be another example on the web.
I suggest reading the articles, trying to follow them ( it's really pretty easy ) and asking specific questions if you get stuck. That way, you give yourself a chance to learn, and we're still here to help if you really can't manage on your own.

man im really confused because i have two big problems and i dont know which should be solved first. if you give me codes so i will learn \ understand my self to see them
i need just codes
please
thanks

Seriously - any code I give you will be no better than the code in an article. If you can't understand an article, then you won't understand the code from me. So, just try.
You realistically have three options
1 - stop coding
2 - pay some one to do it for you
3 - learn how to do it.
I don't have enough info to give you code any better than what's on 100 articles, but even if I did, that would not be helping you. What you want to do is very straightforward. Read an article, think about it, and try to write your own code that follows the (straightforward) example. Then, if you get stuck, at least you tried to write some code, and that alone will help you learn, even if you need to ask here again, posting your code and explaining what you've tried.

You needed to search for delegates - that's what I told you to use, so that's what you needed to search for.

I reiterate - buy a book, a simple book, and work through it. Forget this project for now. If you can't understand those articles, then it's beyond you at this stage, so work up to it.

Hi there
I`m a newbie to the programming in visual basic.
I have made myself a website in visual basic, and precompiling, and the ctrl+f5 utility is all working, and I`m pretty happy with the site.
But now let`s approach the problem:
I have tried to publish the site to my server, but al I get is a list of folders and files. The same happens when I upload via ftp.
I have a sql file attached to the website, but I dunno which program to use.
I`ve tried to use phpmyadmin, but with no luck.
Can anyone help a newbie please?
PS I use Visual Studio 2005

Is ASP.NET running on the site ? If not, the server won't know what to do with an aspx file, you'll get a directory list or a message to say you don't have permission for directory browsing.

Well I don`t think that ASP.NET is running by default, But is there a way I can install it?
BTW thanks for the reply

If IIS is installed on a machine and you install the .NET framework ( make sure it's the same one your site uses, probably 2.0 ), it will install ASP.NET.

Hehe.. I just found out that the webserver doesn`t support asp.net, so I changed my web provider.
This should be up and running in a few days.
Then I will probably drop in and bother all you nice people here with more newbie questions

You might want to open RegEdit and look under HKEY_CLASSES_ROOT. You'll have to modify the registry just as you see here. For example, if you wanted to modify the entry for the .TXT extension, you'll have to find the txtfile key under HKEY_CLASSE_ROOT. Take note of how the registry keys and values are laid out. What you put under here will change depending on what you want to modify. You'll have to look at a bunch of different keys for various file extensions to get an idea of what you have to change and how.
WARNING! Make a backup of your HKEY_CLASSES_ROOT key BEFORE you make any modifications. If you don't know what you're doing and why, you will screw something up and you're only recourse is to restore from the backup!

The following properties are being used within the class, however when they are called from within a private sub within the class itself, intXPositions and intYPositions show a value of zero, even when the value has been set.
public class mainForm
...
Private Sub frmMain_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Initialize plateau.
Dim myPlateau As Plateau = Plateau.Instance
myPlateau.XPositions = 1001 ' x = 0 to x = 1000
myPlateau.YPositions = 1001 ' y = 0 to y = 1000
dtgPositions.DataSource = myPlateau.dsPlateauPosition
dtgPositions.DataMember = "PlateauPositions"
Me.Text = "done"
End Sub
...
Public Class Plateau
...
Private intXPositions As Integer
Public Property XPositions() As Integer

Return intXPositions

intXPositions = Value
End Set
End Property
Private intYPositions As Integer
Public Property YPositions() As Integer
Get
Return intYPositions
End Get
Set(ByVal Value As Integer)
intYPositions = Value
End Set
End Property
...
Private Sub initDataSource()
'Create PlateauPostions, a working dataset that retains information about
'positions occupied on the grid.
Dim dtPlateauPositions As New DataTable("PlateauPositions")
'define attributes

.Columns.Add("xPosition", System.Type.GetType("System.Int32"))
.Columns.Add("yPosition", System.Type.GetType("System.Int32"))
.Columns.Add("occupied", System.Type.GetType("System.Boolean"))
End With
'enforce composite primary key
Dim colPrimaryKey(1) As DataColumn

colPrimaryKey(1) = New DataColumn("yPosition")
'create dataset

Dim intXCount, intYCount As Integer

rowNew.Item("xPosition") = intXCount
rowNew.Item("yPosition") = intYCount
rowNew.Item("occupied") = False
dtPlateauPositions.Rows.Add(rowNew)
Next intYCount
Next intXCount
End Sub

It's hard to say, as you haven't included enough of the code to follow it. You don't have any Instance, dsPlateauPosition or PlateauPositions properties in the class, and you never call the initDataSource method.
I see one problem in the code, though. You only create one DataRow object, so you would be adding the same data row to the table 1004004 times.

True, I actually excluded parts of the code intentionally (remarked with ...). I have updated the code to create a new row each time (see below), but the data set is still not being updated with rows.
Imports Rover
Public Class Plateau
'Singleton class. Must use Instance to initialize.
Private Sub New()
initDataSource()
End Sub
Public Shared ReadOnly Instance As Plateau = New Plateau
Private intXPositions As Integer
Public Property XPositions() As Integer
Get
Return intXPositions
End Get
Set(ByVal Value As Integer)
intXPositions = Value
End Set
End Property
Private intYPositions As Integer
Public Property YPositions() As Integer
Get
Return intYPositions
End Get
Set(ByVal Value As Integer)
intYPositions = Value
End Set
End Property
Public ReadOnly dsPlateauPosition As New DataSet("PlateauPositions")
Public Function isOccupied(ByVal Location As Coordinate) As Boolean
End Function
Public Function setOccupied(ByVal Location As Coordinate) As Boolean
End Function
Public Function clearOccupied(ByVal Location As Coordinate) As Boolean
End Function
Private Sub initDataSource()
'Create PlateauPostions, a working dataset that retains information about
'positions occupied on the grid.
Dim dtPlateauPositions As New DataTable("PlateauPositions")
'define attributes
With dtPlateauPositions
.Columns.Add("xPosition", System.Type.GetType("System.Int32"))
.Columns.Add("yPosition", System.Type.GetType("System.Int32"))
.Columns.Add("occupied", System.Type.GetType("System.Boolean"))
End With
'enforce composite primary key
Dim colPrimaryKey(1) As DataColumn
colPrimaryKey(0) = New DataColumn("xPosition")
colPrimaryKey(1) = New DataColumn("yPosition")
'create dataset
dsPlateauPosition.Tables.Add(dtPlateauPositions)
'initialize positions as not occupied
Dim rowNew As DataRow
Dim intXCount, intYCount As Integer
For intXCount = 0 To intXPositions - 1
For intYCount = 0 To intYPositions - 1
rowNew.Item("xPosition") = intXCount
rowNew.Item("yPosition") = intYCount
rowNew.Item("occupied") = False
rowNew = dtPlateauPositions.NewRow() 'updated!
dtPlateauPositions.Rows.Add(rowNew)
Next intYCount
Next intXCount
End Sub
End Class
