Methods and properties

I am trying to figure out how to make a function so that you can only pick certain arguments for the argument list. Not Overidding the function.

For Example:

Sub New (ByVal value As String, ByVal value2 As String)

I want the value 2 to only have the value 1 or 2.....

Can't i set that up in the argument list? Iv'e looked everywhere and i thought i remember seeing something about it.

Mag

Public Enum MyVals
Val1 =1,
Val2
End Enum

then as your arument for value2, pass in a variable of myVals type.

Not that.....Something like......

Sub New (ByVal value As String, ByValue value2 As String = 1, 2)

So on the call they can only send in those two values.

Example TheCall("weeee", "1") or TheCall("something", "2")

Nothing else can be sent in to the value2 parameter except for 1 and 2.

Why don't you use a boolean for value 2 - so then you would have either true or false.

You may be thinking of the

VB Code:

[b]<AttributeTarget>[/b]Public Function myTest(value1 as string, value2 as string)

I think its AttributeTarget, then again, there's a whole boatload of these < ...> operators that you can apply to methods, properties and classes... sorry i can't be for certain or more specific.

I think this link describes them (further on down when they describe how to validate a property with their own attribute class called validLength

VB Code:

<ValidLength>Public Property Width As Integer

Because ultimately i will have more than 2 items.....like 6

Well for example the messagebox function will only allow you to sellect certain types of graphics like the exclamation point and the red x in its call.

Oh, just use an Enum for the second parameter then.

VB Code:

Public Class1
 
 Public Enum myParameter
   Franklin = 1
   Widge= 2
   Trance = 3
 End Enum
 
 Public Function doThis(value1 as string, value2 as myParameter)
 
 End Function
 
End Class

Thanks For the replies......


Im stupid. Koven tried to tell me....
