int main ()
{
HWND handles[2] = return_two_handle();
return 0;
}

HWND return_two_handle()
{
HWND handles[2];
  return handles;
}


this pops up:


.cpp: In function `int main()':
.cpp:57: error: invalid initializer
.cpp: In function `HWND__* sign_in_two()':
.cpp:152: error: cannot convert `HWND__**' to `HWND__*' in return

will be better to do this way:

void  return_two_handle(HWND &h1, HWND &h2)
{
  h1  = ....;
   h2 = ....;
}

so you can call this way:

HWND handle1, handle2;
return_two_handle(handle1, handle2);

just one little detail,

the function would create those two handles and return it.

it's afunction that starts things and then i need those two handles returned to use them elsewhere.
