Hi people Back in the goold old days of MSVC 4.2 I could do the following to profile my application: 1) Enable profiling 2) Recompile 3) Run 4) See the table of most used functions. Now, under MSVC 2005 I find something called "Profile guided optimizations" what could be nice, but I do not care about that, I just want to know why my application suddenly takes so much time. All "profile" references refer to the .NET stuff but I DO NOT USE .NET, I just use PLAIN C. 1) Has profiling support for C code disappeared? 2) If not, HOW DO I DO THAT pleeeeeeze ??? Thanks in advance for your time (and patience with a C hand) jacob
