OPTION EXPILICIT Forces explicit declaration of all variables in a file.
Option Explicit { On | Off }
OPTION STRICT Restricts implicit data type conversions to only widening conversions.
Option Strict { On | Off }
Define these statements on top of the page.

' FOR OPTION EXPLICIT ON
Dim thisVar As Integer
thisVar = 10
' The following assignment produces a COMPILER ERROR because
' the variable is not declared and Option Explicit is On.
thisInt = 10 ' causes ERROR
'FOR OPTION STRICT
Dim thisVar As Integer
Dim thisObj As Object = New widget
thisVar = 1000 ' Declared variable does not generate error.
' Attempting to convert Double to Integer generates a COMPILER ERROR.
thisVar = 1234567890.9876542 ' causes ERROR
' Late-bound call generates a COMPILER ERROR.
Call thisObj.Method1() ' causes ERROR
Please admit to MSDN..

Hi there, I am new to VB.NET and I would like to create a data grid on a form, which allows me to add data, and save to a database.
The fields on the Grid will be text box, Combo box, and another to allow the user to browse to find a file location.
I have been unable to successfully create this, and I also am unable to find any decent tutorials. Can anyone help please?!
Your help is appreciated,
Maz

Virus checking is a big deal. Companies make their entire business on doing it well. It's doubtful that you can add it to your app as an afterthought. To compete, you need to dedicate many man years of development.

Hi Christian,
I think he meant to call a default antivirus software, already installed on the PC, through his program. I think, this should be easily possible. But even i dont know how to do it ? Can you please guide in this respect, if you have some knowledge about it ?

Thank you! Graus,
But I have heard that products like Symantec Nortan and Macfee provide interfacs for checking files for virus.
Any update in this please let me know
Thank you!

OK, that's not what I thought you said. In that case, I guess your best bet is to check their sites to see which ones offer such an interface, and then buy the one you decide to work with. I have no idea, I've never done that.

I,m Into a project were as im needing to build A proprietary web browser, as i have various code on my webserver, that only allows this Browser to Access the Information, now im guessing there are several ways to accomplish this possibly w/ Cookies, and Sessions perhapes, i'd like to discuss my idea here and have u guys tell me if im heading into the Correct Direction,
what im really needing is a browser that Doesn't use the IE web control OCX so when my web servers Browser detection PHP Code see's it not as IE / Opera / Mozilla / NS / or any other flavor it lets it gain Access, otherwise it Blocks it with my 404 page, can anyone Give me more insite to my idea's thanks alot

Sounds like you need to write an entire web browser. This is a major task, especially if expect to support CSS and Javascript. Good luck.

I've already written 2 web browsers but using the Microsoft web browser control, i wanna create my own web browser control

No, you haven't. You've written a couple of shells around the existing IE web control.
Crash_beta wrote: i wanna create my own web browser control
You'll have a TON of work to do. You'll need the Http classes in the System.Web class to request pages and build a custom request header so the server can ID your browser. Unless you want to write your own HTML parser and rendering engine, you have to find a parser and rendering library to do it for you. There isn't one in the .NET Framework. You'll also have to figure out what you want your browser to support, like JavaScript and CSS. Have fun incorporating that stuff...
Basically, every newbie who comes up with this idea never has a good reason to do it. They only THINK they do. There's always a better way to do what they want.

i think u repeated what i had said earlier , i had said I'd written 2 web browsers but using the Microsoft web browser control " ofCourse " php See's it as a IE Browser< "go figure that"
u had said Ive written a couple of shells around the Exsisting IE web control< " really? i did ? thats amazing" at anyrate I'm still Burning the Flames, and Working on it, till then ill use a ActiveX Object in my page to pass Parameter if no paramter no access, i have like 4 idea's not just the proprietary browser Concept,

Action required :-
Splashscreen to stay untill Progressbar has finished
Public NotInheritable Class SplashScreen1
Private Sub SplashScreen1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Form1.Visible = False
Timer1.Enabled = True
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If ProgressBar1.Value <> ProgressBar1.Maximum Then
ProgressBar1.Value = (ProgressBar1.Value + 1)
Label1.Text = "Loading " & ProgressBar1.Value & "% Complete"
End If
If ProgressBar1.Value = 1 Then
Timer1.Interval = 800
End If
If ProgressBar1.Value = 2 Then
Timer1.Interval = 75
End If
If ProgressBar1.Value = 12 Then
Timer1.Interval = 600
End If
If ProgressBar1.Value = 14 Then
Timer1.Interval = 1500
End If
If ProgressBar1.Value = 30 Then
Timer1.Interval = 500
End If
If ProgressBar1.Value = 50 Then
Timer1.Interval = 250
End If
If ProgressBar1.Value = 75 Then
Timer1.Interval = 100
End If
If ProgressBar1.Value = 96 Then
Timer1.Interval = 2000
End If
If ProgressBar1.Value = 100 Then
Form1.Visible = True
Me.Visible = False
End If
End Sub
End Class
Can anyone tell me why it's not staying?

It's impossible to say why it's not staying up because you haven't shown the code that creates and shows this SplashScreen form. You don't say what your project's Startup Form is either.

Startup form is Form1, and you allready have seen the create /show code.
The forms for this project are :-
SplashScreen
Form1
Form2

No, we haven't. All we've seen is the code inside the SplashScreen, not the code that created an instance of it and .Showed it.

Well according to the tutorial on Dream-in-code i don't need to create a instance of it.
It works well as is, BUT does not stay on screen long enoght.
So you are saying that i need to do something like the following :-
dim frmsplash as splashscreen
frmsplash.show
and this code would be in the handles me.load for form1 ?

Something like that... That's the code you're not showing us, or what the code is around that little section.

No, we can't. What is Form1 ? How is it set in this class ? How is the SplashSCreen instance created ? This is probably the problem, it's probably not a member variable, and is falling out of scope.
The code we need to see, has not been posted.
A progress bar that sets itself based solely on a timer is kind of useless.
