uhhhh... I dunno, just figured I couldnt be that lucky. =D) And I have this really old FPD skeleton in my closet where running a separate app from inside another exe was a total nightmare & waste of time... I havent gone there since.

>I have a luncher.exe that has a Do ['MyApp'] at the end of the prg. Then in MyApp.App, I have a menu option to call my Reports.App. Both of these apps can use the default DS [DS 1], or their own. Actually MyApp is in the default DS. Reports.App is controlled by a generic form to handle report selection and uses a private DS.

If oApp.nDataSession is zero, methods that look for this use the currently selected DS. Otherwise, the method code switches to the DS value found in that property [and switches back to what it was when finished, of course].

Beautiful Mark thank you! That saves me a whole bunch of non-billable research!

Now a new question, has anybody else noticed that the development environment gets really Dr Watson prone when passing around DS ID to manipulate the current DS ever since SP3? I've crashed burned ever time I mess with passing a DS ID ever since SP3, never could put my finger on a specific bug but I've bitched and moaned a whole lot regarding this.
