The VB compiler natively supports adding descriptions using the Description attribute. These will appear in the Object Browser and below the Properties box in the bottom right corner of the IDE, but will NOT show up in Intellisense. For this, you have to use a plug-in like VBCommenter. You can find that here[^].

An example of the Description attribute:

        <Category("Appearance"), _
         Description("Set the number of LEDs to display."), _
         DefaultValue(4), _
         Bindable(True)> _
        Public Property SizeInBits() As Integer
            Get
                Return m_SizeInBits
            End Get
            Set(ByVal NewValue As Integer)
                If NewValue < 1 Or NewValue > 32 Then
                    Throw New ArgumentOutOfRangeException("SizeInBits", "Value must be between 1 and 32.")
                Else
                    m_SizeInBits = NewValue
                    OnSizeInBitsChanged(EventArgs.Empty)
 
                    If m_Value >= (2 ^ m_SizeInBits) Then
                        m_Value = 0
                        OnValueChanged(EventArgs.Empty)
                    End If
                End If
            End Set
        End Property

Is the problem that you have a Sub Main and you're still getting the message or that you want to know why you need a Sub Main?

In a new VB.NET Windows Form project, if you remove the original Form1.vb and create a new form or main module, when you compile that project, it will tell you something like "Sub Main was not found in ProjectName.NewForm". Right-click on the project, click properties, then Common Properties, General, Startup Object, choose which thing will be your entry point for the application. In VB.NET, this will either be a Sub Main of a module or class, or a Form.

The problem comes in because you either removed the Form1 object, deleted the file like you said in your previous post, or you renamed Form1 improperly. When you did this, the Startup Object automatically reverted to Sub Main, even if you don't have one, since you don't have a valid startup form any more. Then when you created a new form, the Startup Object stayed as Sub Main and won't revert back to a valid form automatically.

Did you mean to reply to the original poster? I thought my post read like an explanation...

Multiple Monitors

I have two monitors on two separate video cards and would like to display a form on the second monitor automatically when launched.

I have form A launching on the first screen and form b launching at the same time. I want form B to go to the second screen.

Any help greatly appreciated!!

Thanks,
Bob

The upper left corner of the screen on the primary monitor is 0, 0. So, assuming both monitors are the same size (1280 by 1024, let's say), the upper left corner of the screen on a secondary monitor placed to the left of the primary would be -1280, 0. If the secondary is to the right of the primary, the upper left corner would be 1281, 0. If it's above it's 0, -1024 and so forth and so on...

frm2.StartPosition = FormStartPostition.Manual;
frm2.Location = new Point(-900, 200);

In multimonitor environments use the DesktopLocation property instead of the Location property to correctly position forms.

VB.NET: System.Windows.Forms.Application.EnableVisualStyles()

VB6:

Add the API function InitCommonControls, defined as: void InitCommonControls(VOID);

In VB: Private Declare Sub InitCommonControls Lib "comctl32.dll" ()

Make sure you make a call to this in Form_Initialize:

Private Sub Form_Initialize()
InitCommonControls
End Sub

Then add a manifest file called <appexename>.manifest, so if your app is App1.exe then this file would be App1.exe.manifest. The file must contain the following lines:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity
version="1.0.0.0"
processorArchitecture="X86"
name="Your App name goes here"
type="win32"
/>
<description>Your App name goes here</description>
<dependency>
<dependentAssembly>
<assemblyIdentity
type="win32"
name="Microsoft.Windows.Common-Controls"
version="6.0.0.0"

publicKeyToken="6595b64144ccf1df"

Password viewer???

How do you make a small program which allows you to see passwords??

So, if you see an password in a textbox, whith ****, how can you encrypt this??

Re: Password viewer???

Dave Kreskowiak26-Feb-04 2:09

Encrypt? Do you mean you want to scramble the actual text behind the dots, or you want to see the text behind the dots?

If you want to see the text, you would use GetWindowText or use SendMessage and the WM_GETTEXT message to retrieve the text from the Textbox. BUT! I'm NOT telling you how to get the window handle of the Textbox! Hacking a password is not supported here...

If you want to encrypt the text, you can't. If you encrypt the text, your actually just typing the scrambled characters into the textbox and the program will not know that your password is scrambled and pass on a scrambled (and incorrect) password to whatever authentication process is being used.

To stop this practice from being used on projects I've worked on in the past, I've used techniques like clearing the password from the textbox after 3 seconds or so and have written a textbox control that keeps the password typed in seperate from the textbox. The textbox display is just a plain textbox, without using the Password Character property, that just has asterisks in it that correspond to the number of characters entered. You can use Revelation on it, or some other hack tool that does the same, and you'll actually see a string a asterisks instead of the text behind them.

And no, I can't give you the code for it because it's copyrighted by my employer at the time...

Hiya all. I'm planning on making a program for a card game I have (Munchkin, if you wanna know). In creating this program, I was hoping to declare a Player type variable, if it's possible, and create my own properties like Level, Gender, and so on. Unfortunately, I have been unable to find a way to do this. If anyone can help me, or can think of another way to accomplish my goal (XML files might work, I dunno), I'd appreciate it.

Thanks in advance.

EDIT: In case my post wasn't clear enough, I want something like this:

Dim plrMike as Player<br />
...<br />
plrMike.Level = 1<br />
plrMike.Gender = Male

One of two things you could do:

1) Create a Class:
Assuming VB.NET: You will create a new class library named Player.vb.
Assuming VB6: You will create a new class library named Player.cls.

2) Create a type/structure:
Assuming VB.NET: Create a structure definition using Structure...End Structure.
Assuming VB6: Create a type using Type ... End Type

Well, I went ahead and made a new class library (my new variable type ends up being Munchkin.Player.Character). I can do things now like assign "Male" to Character.Gender, but I can also do wacky things like Character.Gender = "Chicken". Another thing is that the maximum level is supposed to be ten, but I could make Character.Level whatever integer I want, even negatives. What do I do to limit what kinds of genders there are, or specify which ones do and don't work?

John Kuhn10-Mar-04 13:44

10-Mar-04 13:44

Well, you could do a couple of things. You could have an Enum in your project, like:

Namespace Munchkin
    Public Enum Genders
        Male
        Female
    End Enum
End Namespace

Then, you could declare your Gender field like:

Public Gender As Genders

And the only valid thing to put in it would be:

someCharacter.Gender = Genders.Male

You could do the same thing with levels, or you could throw an exception if a character's level is set below 1 or above 10:

Public Class Character
    Private _level As Integer
    Public Property Level() As Integer
        Get
            Return _level
        End Get
        Set(ByVal Value As Integer)
            If Value < 1 Or Value > 10 Then
                Throw New ApplicationException("Level must be between 1 and 10")
            Else
                _level = Value
            End If
        End Set
    End Property
End Class

But guess what? Your Character is starting to sound more like a class than a structure...

>But guess what? Your Character is starting to sound more like a class than a structure...

In that case, I must have misinterpreted your orginal advice; I had a project named Munchkin, a Class named Player, and a Structure named Character. It looked something like this:

Structure Character<br />
        Public Name As String<br />
        Public Gender As String<br />
        Public Level As Integer<br />
    End Structure

But I guess I should do the Class thing and the Structure thing seperately. Anyway, thanks for the help. I'm gonna try the Enum and Exception code now.
