Array of handles

I'm making a program that lists all running processes and gets the handle to the process using OpenProcess() and I had a few questions. I made a struct called Proc that looks like this:

Code:

---

class Proc
{
public:
HANDLE hproc;
PROCESSENTRY32 proc;
Proc(){ hSnap = NULL; }
};

---

I know it's not the coolest thing in the world, but it helped me organize the crap alot. Then I declare an array of Procs. Because I need to CloseHandle() for each OpenProcess() that I have, would it work if I did something like this:

Code:

---

Proc allProcs[256];
...
allProcs[i].hproc = OpenProcess(PROCESS_ALL_ACCESS, TRUE, allProcs[i].proc.th32ProcessID;
...
CloseHandle(allProcs); // no matter how many processes I open, would this close all of them? This could minimize some code if it worked, but I could get around it.

---

Thanks for your answers

oh, btw, can a HANDLE and a HWND sometimes be interchangeable?

...I forgot I had an account here....

Anyways, since I can't make an edit in the above section, here's a correction:

Code:

---

class Proc
{
public:
HANDLE hproc;
PROCESSENTRY32 proc;
Proc(){ hproc = NULL; } //used to be hSnap, but should be this
};

---

Since CloseHandle() wants a HANDLE as it's parameter, I would doubt what you propose would compile.

oh, yea, I forgot that, what I meant was

Code:

---

CloseHandle(allProcs.hproc);

---

would that work, should've been my original example.

That would also fail; allProcs by itself is a pointer to the first element in the array, so you'd have to use CloseHandle(allProcs->hproc); at the very least, but that would close the handle of only the first Proc struct.

ok, thanks, perfect answer, even though it means more code, doesn't matter 'cause it's already implemented.
