Hi! Al,... your impression was right!!! At this time, my most wanted capability in a PTE is that: open the PTE through a comand line instruction from javascritpt embeded in a html page. But my english it's no so good!!! Sorry for that!!! I know that the PTE can open other files (only if you have the program installed). I wasn´t talking to open others aplications with parameters in a "command-line" sentence,... but,... hey!,... it seems to me a great idea too. Yes, I know that some other programs (not all) can´t accept parameters right now,... but that it's a limitation of other programs. Thats, preciselly, it's why I can't use other programs. The capability to run a just simply exe file (without previous installation), and accept parameters in the invocation (like password u others),... and even more,... invoque other files (html's with javascript, .zip, .rar) with parameters,... can be a unique and powerfull capability of PTE. Well,... by the moment,... I'll have to find another way to do that,... or another product. Thanks a lot for your time, and for your help!!! By!
