Detect API Calls

[som1]

I would like to inject a DLL to my target process and detect any API calls that were sent to my target.

For example if someones program calls WriteProcessMemory and sets a value in my target process I would like to detect that and show what process made that call.

Is this possible in a DLL?

Can someone point me in the right direction or show me a simple example I would be greatful.

Check this (http://www.codeproject.com/system/hooksys.asp) article for tecniques and sample code - a DLL that is able to intercept API calls by altering the Import Address Table (IAT).

Are there any other ways or examples? I don't understand this one well.
