Hi all,
When CreateViewObject is called in my namespace extension I use SHCreateShellFolderView to create a system folder view. However, when the user double clicks on folder whithin this view, CreateViewObject is called again, and a new window pops up- instead of repopulating the old one. I've tried having a single instance of the IShellView from SHCreateShellFolderView and using it each time, but that just means that when the user opens a subfolder, nothing happens..
Any ideas anyone? I'm tearing my hair out over this...

I have an app that eats up a bunch of memory with objects (created with "new"), then releases it back to the system (using "delete").
I am monitoring the memory usage with taskmanager, and noticed something strange... the memory does not seem to be given back to the system.
If I minimize the app, the memory is magically recovered by the system, and all is well, even after restoring the app.
Is the memory actually given back, but taskmanager is just out of the loop until the minimize, or is the memory not released until the app is minimized? if so, am I supposed to call some sort of "flush" function to give it back?
Thanks

MS's memory manager is greedy. it hangs onto memory you've free'd in anticipation that you might need it again before your program exits. this makes subsequent allocations faster.

Right, and this is perfectly normal behavior.

TM is actually showing you the address space in use. This has nothing to do with the amount of that address space your program is actually using.

Hello all,
I need to write some application in C++ that act like some chat application.
When client connect to the server - the server need to open new thread for the connection.
My main problem is the communication issue ... i don't know a lot about communication programming in C++ and i need to learn how to do it (specially the issue of open thread).
I looking in Google and i don't find anything.
Thanks for any help. ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Why not look at some Java examples? Java is VERY similar to C++. You can probably find classes in VC++ that mimic very closely the classes you'll see in Java.

I wouldn't even tell an experienced C++ programmer to do this, much less a self-proclaimed beginner. It is easy to have a C++ programmer generate a Java program using C++ as a template, but not the other way around.

Java is very different from C++ in the areas of socket programming and threads. On top of that, both of those areas are OS dependent in C++, whereas Java *tries* to have a standard way for both.

I'll say this --- it will be much easier for a beginner to use Java for "chat" than C++ any day! The Java IDEs (which are free) put VC++ to shame (at least for VC++ 6.0). And there are numerous books that show you "how to" exactly do something --- unlike the Microsoft stuff that never quite tell you everything you need to know about how to solve a problem. For ease of use, I'll take Java any day of the week!

I can argue back on that, but that wasn't the point I was making with my comment. Trying to look at Java code and derive what you would need to do in C++ is not an easy task, and definately should not be recommended to someone who states they are a beginner.
As to your off-topic points:
VC++ (even VC6) was FAR superior to any of the Java IDEs (even the most modern ones) when it comes to certain important features (e.g. debugging). Yes, many of the Java IDE's look prettier and will try to type for you, but more often than not, those things get in the way of development instead of doing what an IDE should do (e.g. help the developer). Granted, there are some things the Java IDEs do better, but as a user of both, I prefer VC over Eclipse or NetBeans anyday. In fact, there are times when Eclipse annoys me so much that I write my Java code using a text editor.
As for books, there are just as many C++ books published (actually more) as there are Java books. Granted, not all of them are terribly useful for beginners, but that can be said for the Java books as well.
Say what you want about Microsoft ... but MSDN (even with its minor hickups) is still FAR more useful than Sun's javadocs which are great at telling you how to call a function, but almost never tell you how to use it.

Have you tried Googling for such?

Hi guys
I have been trying to compile an app in Visual Studio 2005(its a c++ app) but every time i run the proggy after compiling it, it looks like this:
After Compiling: Click Me[^]
although when i click on the Test Dialog button in Visual Studio 2005 it shows the apps layout like this:
Using Test Dialog: Click Me[^]
I started the project in Visual Studio 2005 and the first time when i compiled the app after adding just a simple button ,nothing else, it worked and my app was compiled in the VS2005 format although after adding som functions and stuff it compiled in Visual C++ 6 format!
Visual Studio 2005 Format: Click Me[^]
Visual C++ 6 Format: Click Me[^]
Now my problem is that i want the program to compile and have the style that it has when u click on Test Dialog. Like this:
I want the app to compile and look like this:Click Here[^]
Could someone please help me with this problem?
Thanks

Have you ever tried Google Notebook? After install the software, it will add a button at the bottom-right corner of IE. Dose anybody know how to implement that ? Any reply is appreciated.
