Re: what is the difference between dump and snapshot

hiiii....

The situation to post the above messasge was....

After reading the sentence form Wikipedia "Copy the file system that holds the files in question to another location.This usually involves unmounting the file system and running a program like dump".....

And I know dump is row data copy process...
Snapshot is a image of file system structure(when it takes).

And I understand the dump image contains full data and snapshot image contains only addresses and pointers to the data.

Anyway thanks for the reply...

With regards

hi,

I have used MFC feature pack for MDI application.
I want to add docking pane to mdi child window.
i have used same MDI mainframe docking pane source code for the child window.
it works partially. Because when i open first new child window, the docking pane (from child window) has initial width is equal to 1 only.
but when i open second child window, this time the size of docking pane (from second child window) appears as per required size.
I m not able find out, what 's wrong with first child window docking pane.

At the very end there is an error. I,d like the iterator /it/ to find vectors of integers intelligently and display them in the order the strings in the map container appear. I don't know how to do it. Could anybody possibly help me?

Change that to

std::copy(it->second.begin(), it->second.end(), std::ostream_iterator<int>(std::cout, ", "));
std::cout << std::endl;

(He said, without compiling or testing - give me a couple of minutes...)

The Scribble tutorial from Microsoft is the best intro to MFC I've seen. I started learning MFC with it about 15 years ago. Found this through Google: http://msdn.microsoft.com/en-us/library/f35t8fts%28VS.80%29.aspx[^] but I haven't looked at it. It's probably still the same.

Is there a easy way to move chunk of memory?

Hi

I need to relocate chunk of memory like following:

From:
0-----loc1----------------loc2---------------loc3----------loc4
+------+--------------------+------------------+-------------+
|Header|--------1-----------|-------2----------|-----3-------|
+------+--------------------+------------------+-------------+

To
0-----loc1----------------loc2---------------loc3----------loc4
+------+--------------------+------------------+-------------+
|Header|--------3-----------|-------2----------|-----1-------|
+------+--------------------+------------------+-------------+

Best regards,

If you need to move a block of memory, memmove[^]

However the rest of what you posted does not seem like you want to do that.

there's no simple function to do that, no.

you'll probably have to copy the three chunks to temp buffers, then write them back to the original buffer in the new order.

I have a program running on several PCs at the same time (VS6.0, C++, MFC). The customers data files are stored centrally on the network. He's complaining that the same data file can be open on different computers at the same time and changes made to one are being overwritten by the other.

Is it my problem to check if two PCs are accessing the same file or is it an IT function?

If it is my problem is there anyway to detect programatically whether a file is already open somewhere else?

Thanks

CFile::shareExclusive <-- Just what I need, thanks for the pointer.

I think shareDenyWrite would be better though allowing subsequent users read only access is that correct? Does it display a message indicating read only?

What is 'it'?

Anyway - don't do that, because you still have the problem of other users reading the file while you're writing to it (because file writes aren't atomic operations) and potentially getting an inconsistent view of the file. That's why you get 'single writer, multiple reader' locks for use with in-memory resources - the resource is locked exclusive while the writer's active, but otherwise, multiple people can read the resource concurrently.

If a user tries to open an already open file is a message displayed but obviously that is up to the programmer to display the message. I've been rooting through the code (not mine) and it uses IStorage objects opened with the STGM_SHARE_EXCLUSIVE flag set. Is there any condition where this might not prevent a second copy from being opened?
