what exactly does & mean?

Const ENABLE_LINE_INPUT As Integer = &H2
Const ENABLE_ECHO_INPUT As Integer = &H4
Private Const STD_INPUT_HANDLE = -10&


what does & mean when it's used for numbers?

&H means that a hex number is following.

I still dont get it:D

what does 10& mean? when I check the variable's value it's just 10.... btw I found that on a website.
umm can you explain more plz:)

&H is the only one I've seen, so I don't have an answerer to what 10& means, sorry.

The &H prefix means a hex number is following, while a & suffix was used in vb6 to indicate the number was a long integer. What it is used for in VB.NET I don't know.


PS. The ampersand can be used for string concatination as well.

To create a long constant use this:
Public Const MyLong = 45L ' Forces data type to be a Long.
That is from the MSDN library at this address:
http://msdn.microsoft.com/library/de...eDescribed.asp

It appears the ampersand suffix still forces the constant to be of the Long datatype. But because a Long is 64 bit in .NET, conversions from VB6 have to be done with care. If the constant should be forced to be 32 bit (like a long in VB6), you have to use the % sign instead (the type character for an integer)

So the VB6 code:
Private Const STD_INPUT_HANDLE = -10&

should be converted to VB.NET like this:
Private Const STD_INPUT_HANDLE = -10%

then why not just say
Private const STR_INPUT_HDNALE as long = 10 :confused:
