OK. Thanks a lot for your quick replies. We'll call the question resolved, then?

The whole idea was to _not_ declare the constructor again. I agree that it makes sense to construct the base class object first, but I want the base class constructor to be used if I do not specify one in the derived class.

~ Soumya92

I have a MustInherit class A, something like

Public MustInherit Class A

Protected A as Integer

Public Sub New(ByVal X As Integer)
    A=X
End Sub

Public MustOverride Sub B()

End Class

and I want the declared constructor to be used for any derived classes. However, in derived classes, like

Public Class D
Inherits A

Public Sub B()
    A+=2
End Sub

End Class

VS gives me an error, saying that there is no constructor in A that can be called without any arguments. Is there any way I can inherit the constructor?

I did not upgrade. I should have mentioned that. I completely formatted the drive containing Windows 7 RC, then installed Windows 7 RTM. However, the problem is now solved. The solution was to, believe it or not, use the VISTA DVD to repair the startup. On booting to repair, it immediately prompted me to "FIx and Restart" a startup problem, and hey presto, problem solved. It is sad to see that Windows 7's startup repair fails to detect the issue, while Vista's startup repair fixes it in seconds.

I have a nice hp pavillion laptop. I installed Windows 7 RC (64) on it a few months back. Now having obtained Windows 7 RTM from TechNet, I started the install of Windows 7 RTM (64). During setup it told me "Windows cannot be installed to this disk" and something about not being able to boot off the disk, but installed windows anyway. The next boot, I get "Operating System Not Found". I booted off GPartEd and set the hard disk to "boot" label. The next boot I get "BOOTMGR is missing. Press Ctrl-Alt-Del to reboot". I tried system repair, but it does not detect any problems. Also, there is no 'boot' folder in C:, and bootrec /scanos lists 0 windows installations. What should I do?

"The underlying connection was closed" The site works fine in a browser, once you get past the security error, so I assume that the server does accept post. Is it somehow possible to ignore the certificate errors for the webbrowser control?

~ Soumya92

Everytime I POST data to the server, a webexception is thrown: The underlying connection was closed.

~ Soumya92

I tried that now, and it works. But now I cannot send any POST commands.

I am using VB.net, but samples in any language will do. The problem is that I have to connect to a secure site with an invalid certificate. Every browser based control fails, so I have turned to raw sockets. The website is for internal use only, however its certificate is unverified. I need to know what commands to send and how to respond over https. My socket app, so far, can connect to http, and even view pages. On https, any command like GET /url?parameters HTTP/1.1 gives me an empty response. Thanks in advance.

That was indeed the reason for my problem. Stupid of me not to see it. :-D

Hi All, I am writing a small app that shows a dialog when its tray icon is clicked. The problem is, on Windows 7 the NotifyIcon does not appear at all. I checked both the normal tray and the hidden icons. It is not there. I also checked the visible property of the icon, both at designtime and runtime. Also, any balloon tips to be shown are not shown. Any help in this matter would be appreciated. Thanks.

As part of a presentation software, I decided to write a custom control that provides cool text effects (like in powerpoint 2007). To support transparency, I used Bob Powell's code. Everything is fine in the designer, but when I try to animate the control, it flickers a lot. Double buffering just gives it a black background. Can anyone help me remove the flicker? The code for the class:

Imports System.Drawing.Drawing2D

Public Class Text2007
Inherits System.Windows.Forms.UserControl

Protected Overrides ReadOnly Property CreateParams() As CreateParams
    Get
        Dim cp As CreateParams = MyBase.CreateParams
        cp.ExStyle = cp.ExStyle Or &H20
        Return cp
    End Get
End Property

Protected Overrides Sub OnPaintBackground(ByVal e As PaintEventArgs)
End Sub

Protected Sub InvalidateEx()
    If (Parent Is Nothing) Then
        Exit Sub
    Else
        Dim rc As New Rectangle(Location, Size)
        Parent.Invalidate(rc, True)
    End If
End Sub


Protected Overrides Sub OnMove(ByVal e As EventArgs)
    Me.InvalidateEx()
End Sub

Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs)
    Dim bm As New Bitmap(CInt(Me.ClientSize.Width / 5), CInt(Me.ClientSize.Height / 5))
    Dim pth As New GraphicsPath()
    pth.AddString(Me.Text, New FontFamily("Verdana"), CInt(FontStyle.Regular), 100, New Point(20, 20), StringFormat.GenericTypographic)
    Dim h As Graphics = Graphics.FromImage(bm)
    Dim mx As New Matrix(1.0F / 5, 0, 0, 1.0F / 5, -(1.0F / 5), -(1.0F / 5))
    h.SmoothingMode = SmoothingMode.AntiAlias
    h.Transform = mx
    Dim p As New Pen(Color.Yellow, 3)
    h.DrawPath(p, pth)
    h.FillPath(Brushes.Yellow, pth)
    h.Dispose()
    e.Graphics.Transform = New Matrix(1, 0, 0, 1, 50, 50)
    e.Graphics.SmoothingMode = SmoothingMode.AntiAlias
    e.Graphics.InterpolationMode = InterpolationMode.HighQualityBicubic
    e.Graphics.DrawImage(bm, ClientRectangle, 0, 0, bm.Width, bm.Height, GraphicsUnit.Pixel)
    e.Graphics.FillPath(Brushes.Black, pth)
    pth.Dispose()
End Sub

Public Sub pInvalidate()
    Me.InvalidateEx()
End Sub

End Class
