data converstion from long to int

[wb]

Newbie at .net having trouble with data conversion.

I am using the random constructor and trying to pass in seed value of time
as instructed by help.

rvalue = new random(int)

dim x as long
dim z as integer
x = datetime.now.tick

z = int(x)

when the coversion takes place an exception error is thrown. maybe it isn't
possible to convert a long to an int. But that is what the constructor
takes and the help says that time is a good value to pass in.

suggestions?

Where did you get this code?

dim x as long
dim z as integer
x = datetime.now.tick

z = int(x)

It should be in VB.Net
\\\
Dim x As Long = Now.Ticks
Dim z As Integer = CInt(x)
///
I hope this helps,

'Int' will return a floating point number. It's typically get used to
remove the fractional part of a number. You may want to use 'CInt' instead
which will perform a type conversion. Note that this conversion will fail
if 'Ticks'' value cannot be represented in an 'Integer'.

I have tried all possible combinations of data conversion; all with the same
outcome. The exception gets thrown when the Random constructor takes a seed
parameter such as Cint(Now.Tick). As you state "...the conversion will fail
if "Ticks" value cannot be represented in an Integer" how am I supposed to
pass in the value? The MSDN documentation on Random() uses the code I am
trying to replicate.

Maybe you'd want to "mask" just the least-significant 32 bits (that is,
the bits that change more often) from the value returned by Now.Ticks
before performing the conversion:

Dim Seed As Integer = CInt(Now.Ticks And &HFFFFFFFF)

HTH.
