Hi
In MSDN:
MapUserPhysicalPages:
The MapUserPhysicalPages function maps previously allocated physical memory pages at a specified address in an Address Windowing Extensions (AWE) region
AllocateUserPhysicalPages:
The AllocateUserPhysicalPages function allocates physical memory pages to be mapped and unmapped within any Address Windowing Extensions (AWE) region of a specified process.
So sorry for this question but i really don't know what is the difference between "allocating" and "mapping" memory.
Until now i supposed that they have same meaning but i think this is not true.
Can you please tell me what do these word indicate in win32 jargon?

To "map", "something" should already present. That can be done by "allocation".

Thanks but still i don't understand it.
Please a little more detail.

Does mapping mean:
Translate (from realtive to physical or physical to relative)?
Matching?
or directing?
Which one? or none of them?

Well, in general terms mapping memory pages means that you assign them memory. This is usually done by the operating system, since different processes have independent address spaces wich reside in the same physical memory. So memory of two different processes can be mapped to the same physical memory (of course that requires some complex administration eg. swapping pages etc.). So if you allocate memory it means, that your process declares to the OS that it wants some memory. Some free memory within your process adress space is then mapped to some free physical memory by the OS. The OS guarantees that you can use that memory as if you owned it exclusively, wich is not necessarily the case. Now you can map that memory again to some Address Windowing Extension, wich means you tell the extension "here's some memory you can use", but you are still the owner of that memory.
Long story short - allocate means to tell the OS you need memory - mapping means to map (e.g. virtual addresses of your process's address space) adresses to other (e.g. physical addresses of your machine) addresses. I have no clue whatsoever on AWE, but i think the idea should be the same. This may not be what you wanted, and it may not be complete, but i think it describes the idea.
Hope that helps a little.

 During OS installation ??
I really don't understand what you are trying to do, but if you want to enable Unicode support in your application, there a preprocessor flag you can define in the project settings (sorry, I'm not an expert at all in unicode but other people might be of help here).
So, can you describe your problem more in detail ?

Hi,
LOL, you should get some work in helpdesk. That would teach you how to not be angry to anyone, ever, lol. It is always better to not respond than being rude. No question should ever be answered like this.

Can we change the Volume Name Programatically?
For example we have NEW VOLUME( F: ) I want change this as KIRAN( F: ) Programatically?
Is it possible ,if then how we change?

I think you can try this:
SetVolumeLabel(_T("F:\\"), _T("KIRAN"));
I hope this works.

Can anybody tell me why some VC 6.0 pgms are failing in windows vista?
|
|
|
|
|
What type of failure you are talking about? There are changes/restriction in registry related API's.
There are few other changes. If you take care of this while porting, there should not be any problem.
