Robert,
I don't know how to do this offhand, but you can convert IP addresses to
a single big integer number. What you could do is figure out the start
IP and end IP numbers, then do a simple FOR loop. For each loop
iteration, you could take that number and convert it back to an IP
address and check it. Not 100% how that would work, but maybe this can
point you in a good direction.

Subject: list help
I would like to create a list of IP addresses, let's say, 192.29.22.0 to
192.29.22.255 and then with the list of IPs I already have of valid
users in the same range, search through and find ones that don't match
the range.
For example, I would like the code to search through 192.29.22.0 to
192.29.22.255 and match IPs I have within this range and then list out
IPs that are not there. If I have IP 192.29.22.122 in my list it should
find a match within the range and do nothing, but if my list does not
have IP 192.29.22.100 then it should flag this IP as available.
Is there an easy way to do this without typing in the whole 192.29.22.0
to 192.29.22.255 range? Do I use a list function?
Thanks.

Re: Why would this query not return the correct data?
Considering that your doing a select distinct, the correct output should be 1, 2, 4, 6 and not 1, 1, 1, 1, 2, 4, 6 as you first stated. So it looks like you're getting the very first value 4 times. Try to scope the output and see if that helps: cfloop query=get_days cfoutput#get_days.event_days#/cfoutput /cfloop Or better yet drop the cfloop all together and only use cfoutput cfoutput query=get_days#event_days#/cfoutput /Max On 10/14/07, Rick Faircloth [EMAIL PROTECTED] wrote: Follow-up: When I run the same query below in a query editor, the correct data, 1, 2, 4, 6 is returned.

Re: Running an exe file without CFEXECUTE
Mike, I still don't understand how running a exe on the server where no user will be able to see anything will help? If you execute the file on the webserver (which cfexecute or the Java alternative will do) who will see the result/presentation. Certainly no one from the outside. So unless you're sitting in front of the webserver, you wont see anything that exe might produce.

Re: File permission problem, java vs. coldfusion
And you can, just omit the filename from the path.
A File object in Java doesn't have to be a file in the traditional
sense, it could just as well be a directory.
var myFileDir = THE PATH TO THE DIRECTORY
var myFile = CreateObject(java, java.io.File).init(myFilePath)
if( myFile.canWrite() ) {

Re: Generate Random Number 1000 - No Duplicates
You don't actually need to use the StructKeyExists though
I would take what Russ said and rewrite the function to this:
function getRandomNumberArray(length, count) {
var min = 1 + repeatString(0, length - 1);
var max = repeatString(9, length);
var uniquer = structNew();
while (structCount(uniquer) LT count) {
uniquer[randRange(min, max)] = ;
}
return StructKeyArray(uniquer);
}
Or you could return the StructKeyList(uniquer), if you rather have the
Random numbers in a list

public static boolean verifyZip(String filePath) {

ZipFile zipFile = new ZipFile(filePath);
return true;
}
catch( ZipException ze ) {
EXCEPTION_STR = ze.getMessage();
}
catch( IOException ioe ) {
EXCEPTION_STR = ioe.getMessage();
}
catch( SecurityException se ) {
EXCEPTION_STR = se.getMessage();
}
return false;
}
public static void main(String[] args) {
if( args.length 0 ) {
System.out.println( Valid Zip file?: +
ZipVerifier.verifyZip(args[0]) );
System.out.println( EXCEPTION_STR );
}
else {
System.out.println( usage: java ZipVerifier zipfile path );
}
}
}

Re: java unzip :: verify file
FYI for the list.
It turned out that the issue AJ got was a Java bug for ZipFile. It
turns out that ZipFile doesn't handle corrupt zip files very well - It
throws an InternalError which will just kill JRun. :S
So, I updated my ZipVerifier to use ZipInputStream instead of ZipFile,
which will correctly catch the corrupt ZipFile exception.
