How do you connect Visual Basic with SQL server database?
It depends on what version of VB you are using, and what version of SQL Server you're attempting to connect to. Also, there are several ways to connect from each version of VB to each version of SQL Server (ODBC, ADODB, DSN-less, etc.). Since your question does not provide enough specifics to answer adequately, I refer you to the "Connection Strings" link at the bottom of this page (or you may just type in www.connectionstrings.com in your browser).
How do you use string in visual basic?
A string is a data set in the form of alphanumeric characters and symbols. For example, if you wanted to use a string to concatenate and display a welcome message displaying a user's name, your code would look something like this:
Dim WelcomeMessageString as String = "Welcome to the string demonstration "
Dim FormResponseString as String = form1.text
Message(WelcomeMessageString + FormResponseString)
Here is a simple Hello World application I whipped up using Visual Basic 6:
Private Sub cmdButton_Click()
MsgBox "Hello world!", vbInformation, "Notice"
'displays a message box with an information icon, _
the message that says "hello world", and _
a title that says "notice".
End Sub
The preceding code is for a command button that when clicked, evokes the
button's subroutine.

What is the difference between ASP Net and visual studio Net?
Visual Studio is an IDE, whereas DotNet is a framework. A Framework is a set of usable components which can be used to develop some application, hence Visual Studio is a development environment for DotNet based applications.
Vb program to find roots of quadratic equation?
Dim a, b, c, undroot, root, posx, negx, x1, x2 As Single
Private Sub cmdcompute_Click()
a = txta.Text
b = txtb.Text
c = txtc.Text
If txta.Text = "" Then
MsgBox "Please enter the value of A ", 0 + 32
Exit Sub
End If
If txtb.Text = "" Then
MsgBox "Please enter the value of B ", 0 + 32
Exit Sub
End If
If txtc.Text = "" Then
MsgBox "Please enter the value of C ", 0 + 32
Exit Sub
End If
If a = 0 Then
MsgBox "A can't equal 0 ", 0 + 32
Exit Sub
End If
If (b ^ 2) - 4 * a * c < 0 Then
txtx1.Text = ""
txtx2.Text = ""
MsgBox "Imaginary solution : (b^2)-4*a*c < 0", 0 + 48
Exit Sub
End If
'Calcualtions
undroot = (b ^ 2) - 4 * a * c
root = undroot ^ (0.5)
posx = (b * -1) + root
negx = (b * -1) - root
x1 = posx / (2 * a)
x2 = negx / (2 * a)
'Displaying results
txtx1.Text = " " & x1
txtx2.Text = " " & x2
End Sub
How you can generate an random unique number in visual basic studio?
You can use this function:
Function Random(ByVal Lowerbound As Long, ByVal Upperbound As Long)
Randomize()
Random = Int(Rnd * Upperbound) + Lowerbound
End Function
And use it by using:
whatever.Text = Random(1, 1000)
This example gives a number between 1 and 1000.
Basic defferences between general procedures and event procedures in Visual Basic language?
Although these two terms refer to similar processes there is a technical difference. A procedure is a snippit of code that is a specific list on instructions that a program may execute once or twice. Basically a procedure will only run once everytime it's action is called. A function is kind of like a loop. A function mainly concerns variables where the variable is increasing each time delivering different numbers each time the function is repeated. Here are some examples. A program saves your work when you click the save button is a procedure. A video converter convertes 7,000 frames is a function.
What are the difference between vb studio and vbnet?
VB can be run with native support means you don't have to install any framework, library, run time environment etc in order to run an App which is built by VB.
Whereas VB.Net must requires a Dotnet Framework as a prerequisite for VB.Net app.........
VB app is run efficiently as compared to VB.Net......Because there VB app runs directly On OS kernel whereas VB.Net is firstly run on .Net Framework (CLR)* and then this CLR(Common Language Runtime) executes it on Os kernel so For VB.Net there is an extra of one layer for executing......
*CLR is a .Net Framework core component which translates the VB.Net app (or any other app which is built using .Net) into Machine language code.

That's easy to do!
This script will get the POST data from an HTML form and check if it is a vowel.
$vowels = array('a','e','i','o','u'); // Make variable "vowels" an array with all vowels in it
$_POST['string'] = $string;
if (strlen($string) != 1) { // String is not one character.
echo 'The "character" is not one character!";
} else if (in_array($string, $vowels)) { // Check if string is a vowel based on array
echo $string.' is a vowel!'; // Is a vowel
} else {
echo $string.' is not a vowel.'; // Is not a vowel
}
?>

What are the disadvantages of visual studio?
not much really. The only thing is, is that it costs and takes up alot of room on your pc. if you are downloading, prepare for a long download. Visual Basic is free!
Ifthenstatement visual basic 6.0?

If <condition> Then
Statements ...........
.............................
End If
For Example:
Private Sub Form1_click()
Dim marks As Integer
marks= InputBox("Enter Marks : ")
If marks >60 Then
MsgBox "First Devision"
End If
End Sub
What is the difference between C plus plus and MS Visual C plus plus computer programming?
C++ is simply the generic implementation, based upon the version originally developed by Bjarne Storustrup, and which is considered the standard implementation. Visual C++ is Microsoft's implementation of the language, which follows much of the standard, but is not 100% compliant. However, VC++ includes an extensive and exclusive library that is specific to Windows programming. Competitors such as Embarcadero's C++ Builder have similarly extensive Windows libraries but which are not compatible with Microsoft's.
