Hi,
I came to know the way to auto scroll to bottom, we need to write these following code in AxWebBrowser1 documentcomplete event as,
If e.pDisp Is AxWebBrowser1.Application Then
AxWebBrowser1.Document.parentWindow.scrollto(0, 99999999)
End If
I got problem if the option strict is on as "Option Strict On disallows late binding."
How to solve this error

HI everybody,

Just add a StatusBar on your form (as you would a TextBox), add as many Panels you want in it. Then write any information you want in them.
The Quickest way to get info on small stuff like this is with your good friend "GOOGLE"
Try googling "vb.net Statusbar", "vb.net caps lock", "vb.net ....anything..."

Sir/Madam,

You can validate the format of the email address, but you can not validate that it is an existing address.
This is a regular expression pattern that I use sometimes to verify email addresses: "^[\w\-%~\.]+@[\w\-\.]+\.[\w]{2,4}$". It's based on the specification of how an email address may look, so it might be too strict as some email addresses does not follow the specification. You might want a more relaxed pattern like "^.+@.+\.\w{2,4}$".

Sir/Madam,
I searched a email validation string
Function IsValidEmail(ByVal strIn As String) As Boolean
Return Regex.IsMatch(strIn, "^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$")
End Function
Is this useful.
Thanks and Regards

Sir/madam,
Can i programically call the outlook to send the email in vb.net (Window Applications).
Thanks and Regards

Yes - google for MAPI.
It's much easier to just to take the mail server from outlook and pass it to .NET, thus fixing your code below.

It's called MAPI. As I said. Google for MAPI, there's.NET wrappers for it. I use one in C#, it works great.

Are you sure you have a mail server running on your machine ?

That is not enough. You need an SMTP server to send mail.
You can either install the SMTP server for IIS on your computer, or you can substitute the "localhost" in your code for the name of the SMTP server of your ISP (internet service provider). The second one is the safest bet, as some ISPs only allow sending mail through their SMTP server to prevent spam.

Sounds like you're downloading VB6 code. They are totally different.
No-one will do your homework for you ( well, I hope they won't ). What has your teacher asked you to do ? Is this a console program ? Text display on windows program ? Graphics driven ? 3D ? Do you hope to teach your game how to play against a player ? What code have you written ?

I am building a control I use to edit my company objects...but in some of my forms I do not want a certain button to be visible...I provided a property for the button that I can see at desgn time so that on those forms I can set the button to be invisible:
<Browsable(True), _
DefaultValue(GetType(DevExpress.XtraEditors.SimpleButton))> _
Public Property UpdateButton() As DevExpress.XtraEditors.SimpleButton
Get
Return btnUpdate
End Get
Set(ByVal value As DevExpress.XtraEditors.SimpleButton)
btnUpdate = value
End Set
End Property
But for some reason when I rebuild my project, I lose this setting and the control shows again...Any one have any idea what I could be doing wrong?

Do you want to do it programmatically or manually?
If you want to do it manually, you can change the appereance in display settings.
- Go to Control Panel -> Display.
- Klik apppereance tab and then change it as you like.
if you want to program it you had to change the value in the registry by using registry object and set the value as you like.
