Couple of questions I had over break. 1) Does it matter if you leave MacsBug symbols in your code if you release it to the public, or don't you (you can't reverse engineer programs from the symbols, can you?) 2) I was trying to make my own version of the SFP (I needed more buttons & stuff) and therfore was trying to implement the popup dialog with the current directory name. It is functionally correct, although it leaves about the space of SICN to the left of the text in the Popup area when you click on it (I.E. when PopUpMenuClick() takes over) I subsequently added the SICNs for folders and disks to the left of the Folder name, and it still leaves that extra space. What's wrong??? -- ------------------------------------------------------------------------------ Niko Schuessler "On a two semester mission to engineer where niko@iastate.edu no-one has engineered before.... :-) " ------------------------------------------------------------------------------

The first step in disassembling your code is figuring out where the procedure boundaries are. A tool like MacNosy will do this auto- matically, but if you leave the Macsbug symbols in, its much easier. Also, the names of your routines (as listed in the Macsbug symbols) will often give the hacker some idea of what the routine is used for, which he would otherwise have to get by reading the assembly code. Of course, Macsbug symbols don't tell you anything about the code, data, or variables in the program. If you take out Macsbug symbols, other programmers who find a bug in your code will have a much harder time telling you where the bug is. Apple takes symbols out of the Finder, but leaves them in MPW. Why are you afraid of people disassembling your code anyway? David
