I think it's pretty obvious what the error means. You trying to create an object who's constructor, according the documentation, takes 3, 6, or 7 arguments. You've supplied 5 in your code. These[^] are the possibilities.

Hello,
I am developing a GUI prototype in the VB which comes with Visual Studio 2005. I am new with VB, so I believe it's a newbie question. Everything goes fine until I press "Rebuild All". When I press it, VB drops all my settings of anchors, docking etc. and centers everything. As a result, the main menu, toolbars, status bars all get centered instead of where I chose to dock them. I also tried to select "lock = true" hoping it will stop this behavior, but it does not help. There must be some way to keep the selected alignment properties, but how? Would appreciate any help. Thank you!

The question should be what's causing it to center everything. This is most definately NOT normal behavior.
Does it do this if you create a new project and then just put couple of buttons on the form?

It works fine with a new project. I must have screwed up somewhere, I will look for the source of this abnormality. Thanks!

Did you use any custom controls or non-standard controls not normally supplied by the ToolBox?

No, everything comes from the toolbox. Although this new toolbox in VS2005 is larger than that in VS.NET and offers some new properties. I have used lots of Table Layout Panels and Split Containers, also I use my own graphical resources, jpg files created in photoshop for backgrounds. I have also noticed that at some point VB became very slow while I was modifying the UI, it may be because of graphics though, need to check on it.

Define "lots"... All on one form?? Is there a form with "lots" of controls on it?

The main dialog form represents the main window and so far contains (this is the back bone without small components which I have not placed yet):
1) 1 Main menu,
2) 2 Main toolbars and 1 toolbar in a child window,
3) 5 Table Layout Panels - to position child windows properly, to separate labels from toolbars from work area windows,
4) 2 Split Containers,
5) 1 Status bar,
6) 3 Tab controls (1-3 tabs in each),
7) 1 Tree View.
I don't think it is "lots", at least I would assume that VB should be able to handle it. Maybe it is the inserted images that cause such behavior?

The .NET Framework can handle this number of controls easily. The question becomes is the layout being setup correctly in your code? What the designer lays out when you drop the controls in place, visually might look OK, but in fact, your control is actually not in the container that you dropped it on. You might want to go through your designer generated code and follow it step-by-step to see which containers your controls are actually ending up in.

Yes, it is possible. Macromedia provides an ActiveX control (like flash8.ocx) which can display flash content on a form. You can find it in Visual Studio's COM Components list after installing a flash player on your desktop.
There are also .NET wrappers out there too, that simplify access to this ActiveX.
You can find plenty of info out on the Internet. Here's a good starting point for you.

If you didn’t find an answer,
The simplest way to do that is,
Right click on the tool box. Select “Add/Remove Items…”. Select “COM Components”
Select “Shockwave Flash Object”. Click OK
Draw it on the form
Right click on it and select “Properties”
Type the path to “YourMovie.swf” in the “Movie URL” textbox.
Click OK.

can somebody tell me how the event that is suppose to trigger when the mouse moves over the X button on the form loks like?

There isn't one. There is a message that goes to your form so the window can highlight the button as the mouse moves over it, but I don't know what that message is.
If you can determine the message, you can capture it by overridging your forms WndProc method.

You can try using the MouseEnter event.
Private Sub Button1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.MouseEnter<br />
<br />
End Sub

Not strange at all.

What is WindowClient2 set to? It is set to Nothing. So when you call SendMessage2() you get an exception.
You need to set WindowClient2 to a suitable object.

Hi, I'm trying to create the following scenarion
You have 2 winforms A and B
A has a Sub that will pop a msgbox("oi")
and a button that pops form b
forms b has a button that raise a event on A and run the sub with the msgbox
i tried the code bellow, it worked in a console version, but is not working when in a winform
could you help me?
code bellow:
''''FIRST CLASS
Public Class CClock
Inherits System.Windows.Forms.Form
#Region " Windows Form Designer generated code "
Public Sub New()
MyBase.New()
mobjTimer = New CTimer
AddHandler mobjTimer.evtMinute, AddressOf MinuteEvent
'This call is required by the Windows Form Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
End Sub
Private Sub MinuteEvent(ByVal xintTime As String)
TextBox1.Text = "crap"
MsgBox("Minute's Event")
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

End If
End If
MyBase.Dispose(disposing)

It's not working because you are creating 2 separate instances of the CTimer form and only handle the event of the first.
You see, you've created a CTimer form instance and stored it in a member variable in the constructor. You hooked up an event handler to it there too. BUT... you never did a Form.Show() of this object in your code. The event handler that you've setup was only for that particular object instance which was never used.
Public Sub New()
MyBase.New()
mobjTimer = New CTimer
AddHandler mobjTimer.evtMinute, AddressOf MinuteEvent
'This call is required by the Windows Form Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
End Sub
When you displayed the CTimer form, you created a new form instance here. It is firing an event, but you never set up a handler for this particular object instance. So this is where your problem lies.
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
Dim xx As New CTimer
xx.Show()
End Sub
Here str my recommendations.
- Remove the AddHandler from CClock's constructor. The WithEvent assigned to the member will automatically hook up event handlers for you. (Plus you're missing a RemoveHandler anyways.)
- Append "Handles mobjTimer.evtMinute" (without double quotes) to your MinuteEvent method. This makes it work with the WithEvents keyword.
- Do not create a new CTimer object in CClock's Button1 method! Instead, do a mobjTimer.Show().
