re Ping timeout much longer with 10.3.7
Hmmm. Just a wild guess, but 10.3.8 claims to fix some very long launch latencies in iCal, Mail. that were a problem in 10.3.7 etc. Could be connected?

In Mac OS 10.3.2, we get feedback in a matter of seconds. In Mac OS 10.3.7, it takes over 2 minutes to get feedback. This happens in the terminal window too, so it's not a Rev issue. I'm not into unix enough to know what to look for on Apple's site for a technote on this. ping latency? What's interesting is that the same problem exists for traceroute, even though the docs say that traceroute's wait-period is to default to 3 seconds.

How to build nice repport with Revolution
Hi, I'm a new user of Revolution and it's a real pleasure to work with this soft. I was also an old user of Hypercard since version 1.0 to the last one. Revolution is nice, but I don't find à easy way to create nice repport. Of course, for printing a text or a list I use revPrintField, but I want to create some repports more complex. Just for an exemple, if I want to print address labels using a MySQL database and let the user choose his personnal size of labels. How can I do that ? I think that the repport builder doesn't more exist. I remember the create repport from Hypercard, it was so nice and easy. My software will be used by different countries, so I have to let the choice of the paper size US Letter and A4 for exemple. How I do that with Revolution ?

If you take the case of put 1,2 into myArray[a,b] put 1,3 into myarray[c,d] I believe what Xavier wants (at least, what his posted code gives - though it used a simple table not keys) is v1 = a,c v2 = b,d v3 = 1,1 v4 = 2,3 Note particularly v3 - using the various repeat forms, it has each item from the column. split/combine will remove duplicates - and hence give v1 = a,c v2 = b,d v3 = 1 v4 = 2,3 There's a similar problem with the merge code - repeated values in a column cause loss of data. -- Alex Tweedly http://www.tweedly.net -- No virus found in this outgoing message.

Re: sockets and Windows behavior
On Feb 12, 2005, at 8:36 AM, John Rule wrote: Maybe the problem is in doing broadcast messages in general on Windows (this same code works fine on OSX...Linux is another issue altogether). It doesn't work consistently (I do not always get the callback to my 'with' message, the average is 6 out of 10). Using a 'sniffer', I am ALWAYS getting my response from the devices. It seems like it is just that the messages are not always finding their way back to my callback handler (in Windows XP). Is this a problem, or is there a better way? If the devices are responding to the ip address and port that sent the query, then this might be your problem: The doc is lacking on using UDP. The callback for 'open datagram socket' is not for open. (It would be sent immediately, if it was.) It is for read. Scott Raney says to use that instead of read. If the devices are not responding to the port that sent the broadcast, but to some specific port then I guess the above does not apply; you would be using accept. If the messages are very large or a very large number comes in at once, then Windows will lose some. There are some system parameters that can be tweeked, but I forgot what they are.
