thanks all for your posts.
it's help to do what i want.
to explain all the stuff, in visual studio, you can keep the debugging stuff ( like break points ) and send the outputdebugstring outside the ide ( to debugview for example): i'd try to find the same way, but different soft, different way to think
i know this is not the place for, but, by the way, i'm working on a commercial stuff, and i love lazarus ( even if i have delphi professionel for that ): it's easy, well thought ( the autocompletext on combobox is just wonderfull ), you don't have to learn pascal again
lazarus sometimes crashes: like delphi anyway: but delphi, when you want to reload it, it takes minutes, lazarus is so lite to call back
thanks all people who're working on this stuff: this is really a great tools ( make me back to pascal, after years of c# working )
