do you mean something like this? (or a class that inherits and then
overloads?)
Public Class clsColli
Private colID As Integer
Private colNaam As String
Private colPrijs As Double
Private colOms As String
Public Sub New()
colID = 0
colNaam = ""
colOms = ""
colPrijs = 0
End Sub
Public Sub New(ByVal id As Integer)
Me.New()
colID = id
End Sub
Public Sub New(ByVal naam As String, Optional ByVal oms As String = "",
Optional ByVal prijs As Double = 0)
colID = 0
colNaam = naam
colOms = oms
colPrijs = prijs
End Sub
end class

'my constructor looks like this

ByVal age As Integer)
Me.iTitle = title
Me.iQualificati on = qualification

thanks
Portroe
then you can do as i said :)
you yust have to keep in mind you can't have 2 constructors w the same type
of parameters
ex.
public sub new(x as integer, y as string)
xke= x
yke= y
end sub
public sub new(x as integer, z as string) ' will give an error, you are
passing an integer and a string 2 times the program won't know w one you
mean
xke= x
zke= y
end sub
'you can do this
public sub new(z as string, x as integer)
xke= x
zke= y
end sub

' I want to implement multiple constructor overloads under this

'Overloaded ' ***** Signatures must be different
Public Sub New( ByVal title As String, ByVal qualification As String) '
only two parameters
End Sub
'AND
Public Sub New( ByVal title As String ) ' only one parameters
End Sub
'AND
Public Sub New( ) ' Zero parameters
End Sub
Now your Constructor can be any of the above.
*** Note - here you are overloading constructors. Dont forget, if you
override a constructor, remember to call MyBase.New() from the overridden
constrcutor.

What's the problem? Notice that the different overloads must have a
different signature (number of parameters, type of parameters).

Ok, thanks to some good assistance/advice from people in this group I've
been able to further develop my Distance class.
Since previous posts I've refined my code to accept the unit measurement as
a char rather than incorrectly representing it as an int. I've done this
because I want to develop the class so that it will be able to convert
between values, ie if I add 500 m to 1 km I'd like a correct result given in
metres (1500 m in this...

I'm trying to change the way a treeview works just a bit, i'm pretty new

Hi all,
Im having a problem with my code. Im programming a vector class,
and am trying to overload the () operator in 2 different situations.
The first situation is to assign values, e.g. Y = X(1,2), the elements
1 and 2 of X gets assigned to Y. In this case, the operator ()
overload should create a copy that is unmodifiable. In the 2nd case, I
want do assign values to elements 1 and 2, e.g. X(1,2) = Y. Then in
this case, the values...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
