App Crash on Start-up

**freekill** · 20th November 2009, 18:29

Hi guys. I'm having trouble with my application. My code works well as it compiles smoothly without any error upon build. However, when I tried to run the .exe file I get a crash message.

I'm on Windows XP SP2 and this is the error that I get.

How can I trace what the source of the crash is? BTW, I have other Qt projects which works fine - only this specific app crashes. TIA.

Hi freekill.

It's hard to tell without any peace of code, it could lots of things, are you triyng to use some pointers without allocating them ? You shoud debug your aplication to see what line it's causing the crash.

Hi John. I sure can tell I'm using a lot of pointers since I'm communicating between threads. I currently have 3 threads working on the application. I have a producer thread (I call this capturing thread since it's job is to capture images from webcam), I also have a separate processing thread (called this one computing thread) and the main thread to handle my GUI events. Here's the compiled codes. It's starting to be a big application but there's still a lot to do about it but it should at least work right now. Again, TIA.
