I do the same as I did always in TP7.
I added external programs and made icons for the toolbar. (TP7 ofcourse in the specific way)
I select image(s) in the list and click the icon.
In Tp7 they are passed in the right orientation, in Tp9 not.
I found, that the commandline for the external programms are not compatibel with WINDOWS.
Right way: Each path has to be surrended by Quotes, Pathseparation by blank.
TP9 way: each path start with a quote, the closing quote is missing.
e.g. "d:\.NET\Deslicer\Deslicer.exe "Y:\Art\Illustrator\ART 159.jpg "Y:\Art\Illustrator\ART 157.jpg "Y:\Art\Illustrator\ART 157.psd
I don't beleave that this is the reason for the orientation problem, but it shows the code procedures have been changed.
