U can make use of SQL to generate random strings/numbers. I have patsted to sql query below; hope it helps.

CREATE procedure dbo.GenerateRandomString (@useNumbers bit, @useLowerCase bit, @useUpperCase bit, @charactersToUse as varchar(100), @passwordLength as smallint, @password varchar(100) OUT)
As
Begin
if @passwordLength <= 0
raiserror('Cannot generate a random string of zero length.',16,1)

declare @characters varchar(100)
declare @count int

set @characters = ''

if @useNumbers = 1
begin
	-- load up numbers 0 - 9
	set @count = 48
	while @count <=57

	begin
		set @characters = @characters + Cast(CHAR(@count) as char(1))
		set @count = @count + 1
	end
end

if @useLowerCase = 1
begin
	-- load up uppercase letters A - Z
	set @count = 65
	while @count <=90
	begin
		set @characters = @characters + Cast(CHAR(@count) as char(1))
		set @count = @count + 1
	end
end

if @useUpperCase = 1

begin
	-- load up lowercase letters a - z
	set @count = 97
	while @count <=122
	begin
		set @characters = @characters + Cast(CHAR(@count) as char(1))
		set @count = @count + 1
	end
end

set @count = 0
set @password = ''
-- If you specify a character set to use, the bit flags get ignored.
if Len(@charactersToUse) > 0
	begin
		while charindex(@charactersToUse,' ') > 0
			begin
			 set @charactersToUse = replace(@charactersToUse,' ','')
			end
		if Len(@charactersToUse) = 0
			raiserror('Cannot use an empty character set.',16,1)
		while @count <= @passwordLength
			begin
				set @password = @password + SUBSTRING(@charactersToUse,CAST(ABS(CHECKSUM(NEWID()))*RAND(@count) as int)%LEN(@charactersToUse)+1,1)
				set @charactersToUse = left(@charactersToUse,CAST(ABS(CHECKSUM(NEWID()))*RAND(@count) as int)%LEN(@charactersToUse)) + right(@charactersToUse,LEN(@charactersToUse)- CAST(ABS(CHECKSUM(NEWID()))*RAND(@count) as int)%LEN(@charactersToUse)+2) 
				set @count = @count + 1
			end
	end
else
	begin
		while @count <= @passwordLength
			begin
				set @password = @password + SUBSTRING(@characters,CAST(ABS(CHECKSUM(NEWID()))*RAND(@count) as int)%LEN(@characters)+1,1)
				set @count = @count + 1
			end
	end
end

There are loads of ways to generate unique random numbers, but what language are you trying to this in? Javascript? Flash/Actionscript? C#? VB.NET? Python? PHP? etc etc....

Note: This is the web development->graphics and multimedia forum...
So if it's flash/actionscript related then you're in the right place. But if it's any of the other languages mentioned above, there are dedicated forums for them and you should probably ask there instead!

Cheers for now,
Jas.
