hey, i want to know

how i can make a like.. a custom "function" or whatever its called
so in my command button click event i can call the cutom one and it will do
all the commands in there instead of having to write the same thing for each
control that will do the same thing.

thanks

Copyed and Pasted from the msdn lib:

Quote:

Visual Basic includes built-in, or intrinsic functions, like Sqr, Cos or Chr. In addition, you can use the Function statement to write your own Function procedures.

The syntax for a Function procedure is:

[Private|Public][Static]Function procedurename (arguments) [As type]
statements

End Function

Like a Sub procedure, a Function procedure is a separate procedure that can take arguments, perform a series of statements, and change the value of its arguments. Unlike a Sub procedure, a Function procedure can return a value to the calling procedure. There are three differences between Sub and Function procedures:

Generally, you call a function by including the function procedure name and arguments on the right side of a larger statement or expression (returnvalue = function()).
Function procedures have data types, just as variables do. This determines the type of the return value. (In the absence of an As clause, the type is the default Variant type.)
You return a value by assigning it to the procedurename itself. When the Function procedure returns a value, this value can then become part of a larger expression.

For example, you could write a function that calculates the third side, or hypotenuse, of a right triangle, given the values for the other two sides:

(Toggle Plain Text)

   
  
   Function Hypotenuse (A As Integer, B As Integer)  As String
 				 Hypotenuse = Sqr(A ^ 2 + B ^ 2)
  End Function

You call a Function procedure the same way you call any of the built-in functions in Visual Basic:

(Toggle Plain Text)

   Label1.Caption = Hypotenuse(CInt(Text1.Text),  CInt(Text2.Text))
  strX = Hypotenuse(Width, Height)

For More Information For additional details about the Function procedure, see "Function Statement" in the Language Reference. The techniques for calling all types of procedures are discussed in the section, "Calling Procedures," later in this chapter.

There you go, all this info and more is avalible at msdn.microsoft.com then click on the library link along the top of the page.

no problem, that's what we're here for. the msdn reference is a great resource for microserf programming.
