ok here is the problem I am making a game and the variables work as follows they have a var class which includes the data and a wrapper class which has built in save and load functions which is binary serialization and the var class is accessed through properties now the problem happens when I try to load the var in this case a map it says the object type cannot be converted to the target type
here is some code
Imports System
Imports System.Drawing
imports System.IO
Imports System.Runtime.Serialization
Imports System.Runtime.Serialization.Formatters.Binary
imports System.Windows.Forms
Public Class Game_map
Implements icloneable
Function Clone() As Object Implements Icloneable.clone
return me.memberwiseclone
End Function
Private var As game_map_var = New Game_map_var
default Property Root(byval shallow_copy as boolean) As Game_map_var
Get
if shallow_copy = false then Return var.clone else return var
End Get
Set(ByVal new_object As Game_map_var)
if shallow_copy = false then me.var = new_object.clone else me.var = new_object
End Set
End Property
Sub save(ByVal filename As String)
'on error resume next
dim fs As filestream = New FileStream(filename,filemode.Create)
dim bf As New BinaryFormatter
bf.Serialize(fs,var)
fs.Close
End Sub
Sub load(ByVal filename As String)
' on error resume next
if file.Exists(filename) = true then
dim fs As filestream = New FileStream(filename,filemode.Open)
dim bf As New BinaryFormatter
var = ctype(bf.Deserialize(fs),game_map_var)
fs.Close
Else
MessageBox.Show("The file "& filename & " could not be found", "File Not Found!", MessageBoxButtons.OK, MessageBoxIcon.Hand, MessageBoxDefaultButton.Button1)
End If
End Sub
Property name() As string
Get
return me.var.name
End Get
Set(ByVal new_name As string)
me.var.name = new_name
End Set
End Property
Property tiles() As game_map_var.game_tile()
Get
return me.var.tiles
End Get
Set(ByVal new_tiles As game_map_var.game_tile())
me.var.tiles = new_tiles
End Set
End Property
Public Class Game_map_var

I know all the class = new class stuff is wierd but I have to do that if i dont the debug says that the "object reference is not set to an object" when I try to access the variable this I believe is because a class is a reference type not a variable at least until you use new which this maybe the source of my problem but structures cannot have starting values which then will return "object reference is not set to an object" when I try to access the varaibles

Hi there 
Being too cheap to go out and buy it before learning VB.NET, I downloaded the 2005 Beta1 of Visual Studio. I wrote some programs, and now I've bought 2003 Standard. I've tried to downgrade the code so much as my GUI (controls, etc.) are all back, my code is (mostly fine) and there's no build errors. However...there's been a few issues that I need some help with.
Private Sub form1_closing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
It seems that the older framework doesn't support this, but does anybody know of an alternative that will work?
***
Dim connectme As New Net.Sockets.TcpClient()
Dim server As String = "1.1.1.1"
If connectme.Connected = True Then //
Property connected as Boolean doesn't exist in this older framework? Anyone else know how to check?
***
For this one, I'm using NotifyIconEX, and with the EXACT same code, the EXACT same controls, references, etc. When I try to set notifyicon1.visible = True, I get "Object Reference not Set to an Instance of an Object".
***
For some reason, whenever I startup this program, Main.vb (the primary form), is ALWAYS blank, even though I have everything set up in the designer. This NEVER happened in VS.NET 2005. I have yet to figure out how to get around this.
***
All of these worked PERFECTLY prior to the code conversion. If anybody could give me ANY advice, it would be GREATLY appreciated.

Hello,

In Visual Basic .Net 2003, you can handle the Closing event with:
Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing
End Sub

I am not sure of the problem here... You should check to see if the startup object is the Main.vb (right click your project inside of the solution explorer, and then select properties. You should see "Startup Object:" with a combobox that has your startup object.). Another thing that could be wrong is that the "Visible" property on each control is set to false.

Hi there
Thank you very much for your code sample, I shall try it this evening.
With regards to the second thing, I have tried BOTH of what you said. I don't even get a title for main.vb...just an empty window with an icon...I've narrowed it down to a certain form but it still makes no sense...
Thanks again,
Head Admin,

VB 6.0
I'm trying to create datagrid type control (5 rows 10 cols) that is connected to an access database table. The data is being pulled from several different tables to feed the main table. A combo box is used to query the data from the different tables.
i.e.
Col 1: plain text, user entry
Col 2: combo box tied to table (user list)
col 3: combo box tied to table (state)
col 4: checkbox weither is active or not
col 5: another combo box from another table
etc.
Data grid may not be the right thing to do. So far I haven't found any reference to this except in vb.net (can't get pass the database connections It's ok if I'm using 1 table with 6 fields). I can creat this form in MS Access but how do I recreat it in VB6.0?

If you're jumping from VB to assembler, I suggest you may well need an intermediate step. You've got my vote for confidence tho.
Microsoft used to publish an excellent book on the subject, I don't know if it's still around, but it's worth having a look on Amazon and also ebay. Sorry, I forget the title, but if you google Microsoft Press assembler, I'm sure you'll find it.

Nope. That's the Intermediate Language that all managed languages compile into.
Assembly Launguage is pretty much a dead art form under Windows. I think Microsoft stopped selling its Macro Assembler about 4 years ago. It's still available as an MSDN Subscriber download though.
What your refering to is actually here[^] on Amazon. There are other titles listed on that page that still cover the topic.

Thank you very much for your comment. But I already order this book[^] online. Do you think it is a good book for me as a beginner which never know about assembly programming language??? On the other hand, could you give me some advantage that assembly programming language could do for us???
Thank in advance

Oh well, it's not assembly language...
[EDIT]
Whoops, I thought you were talkinga about the IL book...

Like I said, in Windows it's a dead art. It's EXTREMELY tedious, but in speed critical code, it can be worth to time to write the machine code by hand for the best possible optimization.
Mind you, the only Visual Studio language that lets you write machine code in-line is C++. None of the managed languages will let you do this.

When i create this programe it will give error
Public Class Form1
Inherits System.Windows.Forms.Form
#Region " Windows Form Designer generated code "
Public Sub New()
MyBase.New()
'This call is required by the Windows Form Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
End Sub
'Form overrides dispose to clean up the component list.
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub
'Required by the Windows Form Designer
Private components As System.ComponentModel.IContainer
'NOTE: The following procedure is required by the Windows Form Designer
'It can be modified using the Windows Form Designer.
'Do not modify it using the code editor.
Friend WithEvents Button1 As System.Windows.Forms.Button
Private Sub InitializeComponent()
Me.Button1 = New System.Windows.Forms.Button
Me.SuspendLayout()
'
'Button1
'
Me.Button1.Location = New System.Drawing.Point(64, 80)
Me.Button1.Name = "Button1"
Me.Button1.Size = New System.Drawing.Size(152, 24)
Me.Button1.TabIndex = 0
Me.Button1.Text = "Button1"
'
'Form1
'
Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13)
Me.ClientSize = New System.Drawing.Size(292, 273)
Me.Controls.Add(Me.Button1)
Me.Name = "Form1"
Me.Text = "Form1"
Me.ResumeLayout(False)
End Sub
#End Region
Dim frmstring As Object = "From2"
Dim frm As Form = frmstring
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
frm.show()
End Sub
End Class
|
|
|
|
|
|
|
Dim frmstring As Object = "From2"
Dim frm As Form = frmstring
What do you think those two lines should do? First you assign the string "From2" to the object variable frmstring. Then you want to assign this string into the Form variable frm. This doesnt make sense and is the cause of the error.

That reminds me of one of the mistakes that I made when I was 8 or 9 years old when I was first learning to program and I read that you could make the computer sound in different "voices" (what they meant was altering the sound to emulate basic sounds like some instruments) and I tried to write code replacing the pitch variable with a string and then wondering why it didn't work and didn't say anything. (As luck would have it I got a speech synthesiser for my next birthday so I could get my computer speak some words)

POS: "Piece of Fill in your term for excrement here"
I can't complain really. I had an old Bally Game Console that had a BASIC cartridge with a WHOPPING 1.8K of RAM. Yes, your heard that right 1.8K. Ever try typing in programs with a keypad that looked like a calculator?
From there, I moved up to a TI-99/4A with a speech sythesyzer and the Expansion Unit that was bigger than 2 bread boxes and an additional 32K of RAM. Whoo Hoo! Those were the days!

Hello,
I have been working in ASP.NET for a few months and i bought a few components.
I really like it because i get things done really fast and most of controls are really good.
Now i got a hit counter in http://www.codeproject.com/aspnet/fastcustomhitcounter.asp.
Is it possible to transform this code and use it as a control?
Can someone help me out? I never did something like this.
The code doesn't seem very complex.
Thanks,
Miguel
