Thanks for your replies, I'll give a look at what you just suggested soon, and yeah KERNEL32 looks kinda complicated really! I guess I need to play with the winsocket first, I used to write winsocket programs cli/srv in the past and I had a look at the UNIX socket source code back in the time. The bugzilla is filled with data yeah, but some times you find somebody mentioning a crash for an installer or an application or something and I suppose that the Coder should run the same App as the reporter did, so that he can resolve the issue and debug it in details and this required getting the software before everything and requires more disk space. I'll come back if I did anything new which I think it will take some days just to get familiarised with the code first but at least it's a big joy & fun to spend time on [Wink]
