Maybe i didn't ask right the question.
I know the difference between KEY k; and KEY *k; but i really care that the fact *k is allocated in free memory has some advantages?

OK but if you use a member instance
<br />
class CMyClass<br />
{<br />
private:<br />
KEY k; <br />
};<br />
then k is allocated wherever the instance of your class is allocated. You can use
heap
<br />
CMyClass* pMyInstance = new CMyClass();<br />
or stack
<br />
CMyClass MyInstance;<br />
If you're allocating really large amounts of data you definitely need the heap, possibly even look into the Virtual Memory API. In general its often best to leave the decision on where to allocate data up to the code that uses the data rather than trying to make it part of the data.
"The secret of happiness is freedom, and the secret of freedom, courage."
Thucydides (B.C. 460-400)

Putting a * there means that it is a pointer to a KEY structure, whereas no * means that it is actually a KEY structure and the required memory to hold all the KEY data is set aside for it.

Do you mean is it safe to define a structure within a structure?

Watch out for memory alignment issues if you are going to use these keys (I'm assume they will be crypto keys) with raw memory access. You can change the way the object is laid out in memory with the #pragma pack directive. It may not be a problem though, depends on how you'll use your struct (Actually it would show not so great design if you'd need this, but there may be performance reasons).

Microsoft have published a set of "lovely" documentation on MSDN to accommodate for setup apps; it's called - rather daringly - the "Setup API" - take a look here.
Hope this helps,

Hi all,
I am facing a strang problem for ImpersonateLoggedOnUser() on Vista 64.
I am having a service and it internally launches a dll and that dll impersonates to paricular domain user. The code works perfect on XP, 2k3, vista 32, XP 64. But on vista 64 the service crashes.
Does anybody have any idea why it might be creashing?
Even i am not able to remote debug it. For remote debugging i put a message box in the dll whenever it pops up i remotely attach to that process and click on the message box for debugging. But on vista i cant see any message box. So how should i remote debug the code on vista 64?

Hi All
How can i get removable drive letter in MFCvc++2005? Plz give some tips..
|
|
|
|
|
You can use GetLogicalDriveStrings() to get a list of availible drives (documentation here), then for each one use GetDriveType() (documentation here) to determine whether it is a removable drive or not.
Hope this helps,

Derive a your class from CEdit and handle right button click.
Hope it helps.

Yes, you can do that.
Derive your class from CEdit, and handle the WM_CONTEXTMENU message.
See this[^] MSDN page about WM_CONTEXTMENU.
If you only handle the right mouse message as another posted recommended, your user will still be able to get the context menu via the keyboard.
