Re: [U2] [UV] Conversion code for week number
There isn't one, and for a very good reason - you have to nail the business rules, and these won't be the same everywhere. For example, on what dat does your week start? It's Sunday for you (I assume, since you're in Australia), but it's Monday in the USA. Some businesses run Thursday through Wednesday as their week. The other business rule is the definition of week number 1 in the year. Assuming that you want to implement the ISO 8601 standard format Wnn, in which every week has seven days, you must decide some kind of rule for week number 1 - for example the first week that has four dates in the calendar year. Using such a rule January 1st is often in week #53 of the preceding year. Of course, if you don't require seven days in every week, and week number 1 starts on January 1st, then you can go with something like Int(Oconv(TheDate, DJ) / 7) --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/

Assuming this is UniVerse on UNIX, you have the PORT.STATUS command in the UV account, and you have ipcs -m | grep aceb at the operating system level. If it's Windows-based UniVerse you still have PORT.STATUS. The equivalent of ipcs is shrdump, but you don't have an equivalent for grep. So you need your own mechanism for parsing out the aceb entries. --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
RE: [U2] UniObjects .NET - Security Best Practices, Connection Pooling in UD
[ad] On the decompiling of .net source code - I am about to release some exciting new software on this front to help in the security of .net applications, including obfuscation, encryption, virtualisation and one click deploy.

Following the MVC design pattern, when building any web app it's best to funnel all data access through a single Data Access Layer (DAL). This is in preference to having MV-related code in every page and class throughout a web application. This makes maintenance easier, allows you to switch the back-end for some or all functions, and allows for changing connectivity tools - all without changing the entire front-end. This also allows you to get one person to do the front-end access and someone else to do data access. Someone who grew up on a green screen may not be adept at creating an attractive or fully functional UI. It also follows that someone can change the front-end, even to something completely different like a web service, without any changes to the DAL. One of the best security methods is to not give people access to source. Put your DAL into a DLL and take the source off of your deployment system. If someone hacks in there they will be much less likely to find vulnerabilities in your DAL code. And because .NET code can be de-compiled, obfuscate your assemblies. Security is handled at different layers including transport and application. Transport security means using HTTPS from client to server, and maybe SSH or tunneling for web server to DBMS. Application security involves authentication and authorization. In other words, only allow people in with an ID and password, and then ensure that only people who fit a given role are authorized to access specific functions. This prevents someone with a generic ID from maliciously or accidentally executing things they shouldn't. Do not allow users to enter data which then gets executed blindly by queries. I think this is one of the biggest faults in MV applications when a new UI is added. This is known in the RDBMS world as SQL injection but we are just as subject to queries being tweaked if your code does not carefully screen data entry. I don't use UO.NET so I can't comment on its pooling details. I do sell, support, and develop with mv.NET which has its own pooling mechanisms, and that allows fine-tuning of license limits. mv.NET is a superset of UO.NET, and even uses UO.NET underneath as a basic transport tool. I've also found that UO.NET requires full permissions to do almost anything, and no one seems to be able to tell us what the absolute minimal permissions are which are required to run it. That's not very security-friendly... For assistance with any of the above, feel free to contact me. Tony Gravagno Nebula Research and Development Worldwide distributor for mv.NET TG@ removethisNebula-RnD.com Robert Kubarych wrote: Does anyone have any security best practices for building web applications using UniObjects for .NET? I've placed the connection string in web.config and encrypted it, as well as created a separate remote account with a stripped down VOC.

I also tried to dial down the asp.net trust level runs with, but it seems that uniobjects for .net needs to run with full trust. I guess it's not possible to use connection pooling until UniData 7.1.

Re: [U2] [UV] Conversion code for week number
Likewise for the business definitions of months and years. I've got clients that have 13 EVEN 4 week months and one has 12 'months' offset by no-one knows why days and an off year. For example, today, July 11, 2007 is period 06/08, meaning period 06 in year '08'. I ain't making this stuff up. The 13 EVEN 4 weeks months client has a parent company in Holland. The 06/08 client has their HQ in USA and offices in Belgium and China. Go figure. It's heavily dependent on control tables as I haven't been able to create a calculation using a base date and constants to tell me what period September 27, 2004 was in. BTW this was one of those Y2K things that didn't get resolved, ie the 06/08, so theres dozens of dict items for sorting in the long-term history files. One of my client's software REQUIRES that the end of month processing is performed exactly on the last day of the month, regardless if it's a saturday, sunday or New Year's Eve. Who were the brain surgeons that wrote this? I've offered to add some hamburger helper but they wouldn't pay for it as it's the way it's always been... Finally, what is the calculation that MV uses for its internal dates? (Don't bother telling me the base date, what's the calculation? I don't think it's Thirty days hath September...)
