Remember in the good old days of DOS where we could intercept calls to the operating system by changing a vector in the interrupt vector table? Well, how can I do the equivalent in Windows? I would like to write an experimental program that would simply count the number of times a particular Windows procedure was called. If I could intercept these calls, I could maintain a counter and then proceed to call the real Windows procedure after I update my counter. Any ideas? Also, what about intercepting Windows messages? I believe the program POSTMAN does this. Any ideas on that? David Sims...dsims@uceng.uc.edu
