API Spying

[JohnnyBGood]

I need to write a program that can monitor the activity of another program running on my computer. As preliminary research, I downloaded the API Monitor program from rohitab.com, to try to find which calls I would need to intercept in order to monitor the events I'm interested in. Unfortunately, I could not find API calls whose parameters contained the information I needed, even when I filtered by each API category separately.

Are there calls that API spy programs like this miss? If so, how can I find the calls I'm interested in? The only thing I know is that they correspond to different images appearing and disappearing the applications window.

Thanks for any info,
Johnny

NoHero,

Thanks for the like. This article seems, however, like a little more firepower than I need. My understanding is limited here, so I could be wrong. But all I'm interested in is API spying, which I believe is not as difficult as API hooking. That is, the only thing I want to do is see the API calls being made (and their parameters). I don't need to replace the windows API functions with my own, for example.

Is my understanding correct here?

If so, could you offer another reference geared my toward my goals.

Thanks again,
Johnny

Try our tools.

Maybe it is your goal.

Auto monitor all api calls and parameters input / output, didn't need rebuild your application and didn't need your source code.
