Kevin posted the tentative schedule for the FoxForward conference. Looks like a good schedule with three simultaneous sessions and several repeated sessions. No time better than today to tell Kevin you want to go to this conference and get registered.
Only 24 days until the conference kicks off in Hotlanta!
I was getting creative this evening with the VFP Session class. I was getting tired of changing the DataSession each time I created a private DataSession with the following code:
loSession = CREATEOBJECT("Session")SET DATASESSION TO (loSession.DataSessionId)
So I created a class in a program and added this code to the Init() of the Session class:
SET DATASESSION TO (this.DataSessionID)
This does not work, the DataSession stays with the current DataSession. So I created a custom method in the Session class and called the method externally. Same result. Here is my test program:
LOCAL loSession as Session
?"--------------"?"Should be default DS 1: ", SET("Datasession")
loSession = CREATEOBJECT("Session")SET DATASESSION TO (loSession.DataSessionId)
?"Should be DS > 1: ", SET("Datasession")loSession = .NULL.
?"Should be default DS 1: ", SET("Datasession")
* Now work with a customized session classloSession2 = CREATEOBJECT("pssSession")?"Would think this would be DS > 1 after set in " +; "Init(): ",; SET("Datasession")
loSession3 = CREATEOBJECT("pssSession")loSession3.SetSession()?"Would think this would be DS > 1 after set in " +; "Init() and custom method: ",; SET("Datasession")
loSession2 = .NULL.loSession1 = .NULL.
?"Should be default DS 1: ", SET("Datasession")
RETURN
*************************************DEFINE CLASS pssSession AS Session
DataSession = 2
PROCEDURE Init * Does not set the datasession to the * private DataSession, why? SET DATASESSION TO (this.DataSessionID)ENDPROC
PROCEDURE DestroyENDPROC
PROCEDURE Error(nError, cMethod, nLine)ENDPROC
PROCEDURE SetSession * Does not set the datasession to the * private DataSession, why? SET DATASESSION TO (this.DataSessionID)ENDPROC
ENDDEFINE*: EOF :*
In my mind it should work and for some reason I could not explicitly understand why it does not. Then it hits me, the object is created in the current DataSession, thus when code returns from the Session object back to the calling program, VFP is automatically returning to the current DataSession. This is a common trap I see developers falling into when debugging code that is changing data in an object that was created in the VFP Default DataSession (DS 1). Not exactly the same thing, but very similar. Tonight I fell into the trap.
I proved this was the case by adding code in the Init and SetSession methods to display the current DataSession after the switch, and the DataSession is getting set in code, then reset when returning to the calling code.
Now I understand why I always use the following code when creating and moving to a private DataSession:
loSession = CREATEOBJECT("Session")SET DATASESSION TO (loSession.DataSessionId)
Maybe this will save you an hour of frustration down the line.

I am very happy to announce F1 Technologies is officially a Gold sponsor of Southwest Fox 2007, and is making a very generous offer to each and every registered attendee of Southwest Fox. Here is the official deal:
Wow. Mike and Toni have always been big supporters of the conference, and this is another fine example of F1 Technologies commitment to the Fox Community.
There is still some time and space available if you want to get registered. Only 66 days until we meet in Mesa!
Thanks Mike and Toni!
Catching up on the sponsors front… I want to announce two new sponsors recently signed up:
1) The Intellection Group, Inc. is a bronze sponsor. Dave Bernard is one of the leaders of this company and speaks at VFP conferences, and has been a friend of Southwest Fox at past conferences by writing up coverage on the UniversalThread. Dave’s company does some really cool stuff with Visual FoxPro on the Web, and is well know for his mantra: “There are no technical problems, only business problems.”
2) Servoy USA Inc is a gold sponsor. Servoy is making a serious push to FoxPro developers with their Java application development and deployment tools. I really do not know much about this company, but figure this is one of the reasons they are coming to Southwest Fox – to get their message out to the Fox Community.
More details about all the Southwest Fox Sponsors can be found here: http://swfox.net/sponsors.aspx
I am happy to announce I will be returning to Germany again this November to present at the 14th Microsoft Visual FoxPro Developer Conference 2007. This is a fantastic conference put on by Rainer Becker and his team. Rainer has an excellent collection of presenters presenting 60 VFP sessions:
English speaking: Marcia Akins, Craig Berntson, Steven Black, Jim Booth, Alan Griver, Doug Hennig, Venelina Jordanova, Andy Kramek, and Rick Schummer.
German speaking: Marcus Alt, Rainer Becker, Joachim Durr, Sebastian Flucke, Uwe Habermann, Jochim Hilgers, Kirsten Hinrichs, Armin Neudert, Michael Niethammer, Patrick Scharer, Markus Winhard, Christof Wollenhaupt, and Jurgen “wOOdy” Wondzinski.
I will be presenting four sessions:
The conference is held at a terrific conference center that serves the best food you could ask for. There are lots of opportunities to network and vendors to visit as well. If you want to learn more about this popular conference you can read some of my blog entries in November 2006 and 2005 (see the index on my blog). I really recommend this conference!
I am please to announce Mike Roof is the lucky winner of the White Light Computing $300 Scholarship for the Southwest Fox 2007 conference. Mike’s company is sending four people to the conference so they increased their odds of winning {g}. I talked to Mike yesterday and he is very psyched about not only attending Southwest Fox, but he is also attending the West Wind Technologies Double Impact training the two days before Southwest Fox. We laughed how much his head will hurt after listening to Rick Strahl for two days, followed by two and a half more days of intense conference sessions. A fantastic training opportunity for any developer. It sounds like a lot of developers are taking advantage of this year.
Sorry for the delay in the announcement, but I ran out of time before my vacation and forgot to hold the drawing. Mike’s name was drawn by the lead marketing advisor here at White Light Computing out of the 85 names registered by July 1, 2007.
Congratulations Mike! Only 76 days until we meet in Mesa!
I really thought the month of July would be really slow at the Southwest Fox registration headquarters because the deadline for early-bird registrations ended, but they keep on coming and today we registered our 100th person to attend the conference. Doug will be updating the Who’s Coming list soon, which now stands at 116 people including the presenters. Note: not all the people are on the list because each person has to opt-in.
Most of my expectations have been exceeded, and we are well on our way to breaking all records for Southwest Fox attendance. Only 78 days until Southwest Fox!
I am looking forward to seeing you in Mesa!
Today I received my June/July 2007 issue of the Advisor Guide to Microsoft Visual FoxPro (AGTMSVFP) and they implemented the Journal format (similar to fading FoxTalk 2.0). I like the change for a couple of reasons:
1) It will be more profitable to Advisor Publications since they are not printing in many colors on glossy paper. A profitable Advisor will produce this publication longer, which benefits the Fox Community.
2) No smearing. The glossy magazines seem to smear in my hands. I am not sure if this is something that only happens to me, but I hate ink smears on my fingers.
3) Same great authors and content.
