How to get the Last Active Date of a Process?

I have an assignment were in I have to print the last active date of the process usin开发者_StackOverflowg a COM In Proc Server in C++. I tried doing that with getProcessTimes() function, but that gives me an access violation error.

First of all, I want to know if there is anyother command that gives the last active date of the process..

Second what is the problem with the following code

FILETIME ftCreation, ftKernel, ftUser;
GetProcessTimes(hProcess, &ftCreation, &ftExit, &ftKernel, &ftUser);`

I tried memsetting and several other alternatives but nothing works...

Here is an article that demonstrates how to use GetProcessTimes. It includes sample code. Another option is using WMI and the WIN32_Process class, which also has this information. Here is an example of how you would use WMI.
