whats & means in VB?
Hi Guys,
I have a question here...it may be simple to some but is bothering me...
whats the function of & in VB? some times I see assignment statements like x& = ....
In graphics programming, whenever we need to get the RGB value, we use &H100& and &H10000<--for this case, how come there is no & at the end of the hexa, just like &H100&?? In RGB case, &H i believe it means Hexa right? what about binary?
Thanks alot for your time guys...

The & after a variable declares the variable a long, after a number "forces" the type of the number to be Long
That is:
dim i& ''is the equivalent of "dim i as long"
i = &hFFFF '' &hFFFF is a short (because the default is Integer), so i = -1
i = &hFFFF& '' &hFFFF& is a long, so i = 65535

The '&' character is also used to concatenate things in VB.
For example:
Dim a As String
Dim b As String
a = "This is "
b = "an example."
Label1.Caption = a & b
The caption on the label would be: This is an example.
