[2005]Values at end of Constant ex( &h1) ????

[smilbuta]

Im sorry to the elite coders here but i have a realy bad noob question.


What are the refrences or values at the end of certain lines of code. I have come across an instance i need to use a constant that holds a value like this and i want to understand what it is passing or representing.

Public Const RESOURCETYPE_DISK As Long = &H1

THe underlined is what i'm curious about, how does one read that??

Thanx....

That represents the hex value 1, as opposed to the decimal value 1
&h1 = 1
&hA = 10

[smilbuta]

ahhh!...

so the &H denotes that the next value is a HEX Value

so &H1A1 would be 000110100001(bin) or 417 right?

so in VB would &B be a binary ?? and im asuming the default is simply a decimal....

Correct

Nope, I don't believe there is syntax of this nature for binary

and im asuming the default is simply a decimal....
Correct

There is no way to specify a binary literal. Standard is decimal and you can use &H and &O for hexadecimal and octal respectively. If you want to be able to specify a binary value you can only do this:

Dim int As Integer = Convert.ToInt32("10010110", 2)

The '2' specifies to convert from base 2.
