Hi Martijn, This is strange. > The problem is that gROOT->ProcessLine() does not work: It should work (especially in your case). It should not mention TFile in case of failure. Can you be more explicit about: - the actual argument to ProcessLine - the actual error message. > Yet this can only work as long as my program remains interpreted. More accurately, it will require your symbol to be exposed to CINT (they could be either compiled or interpreted). > I could execute it directly with arguments, in > both interpreted mode and compiled mode. As long as your properly exposed the symbols (generate the dictionary) gROOT->ProcessLine is your easiest and most flexible way of handling this (but there is several other possibilities).

I first load this Macro with gROOT->LoadMacro() so it is not loaded several times (with related warnings). Then I would like to execute the main method (with the same name) with some arguments comming from my user interface program. The problem is that gROOT->ProcessLine() does not work: it seems to open some new temporary TFile in which my arguments (although my program is mainly in interpreted mode) are not recognized. The only solution that I see currently is making a new macro file on the fly in which resides only the call to my function with corresponding arguments. Yet this can only work as long as my program remains interpreted. What I would like to do is get back my method (which is not a class method) from some TCollection (yet I didn't find which one) where from I could execute it directly with arguments, in both interpreted mode and compiled mode. Could someone help me on this, Best regards, Martijn Schellekens
