It isn't bad. It just takes the longest because it is where all the large or aged objects are placed. This means it doesn't have the same performance as a G0 collection.

Large objects (IIRC >85k) have their own heap separate from the G0/1/2 heaps. It's managed differently in that objects are fixed and the heap doesn't compact after a collect. Instead it uses a c++eqsue traversal algorithm to find a suitable place to store new objects.

And despite reading about it a week or two ago, I didn't quite get it right. The allocator prefers the end of the heap to free space except when it would otherwise be forced to grow the heap. In certain unexpected circumstances this can bite you badly.

To reiterate again, you need to know what you are wanting from the GC before you start messing with it. Oh and Microsoft claims the the GC in VS 2010 is "Better", whatever the heck that means (I do not recall a time when microsoft released a product and claimed something about it was "worse" or the same for that mattter).

Well obvious possibilities occur: One would be doing fewer G1 collects to reduce the number of objects making it to G2. The second would be to change the large object heap to avoid the sort of problems in the article I linked elsewhere in the thread. Changing the end of the free memory chain would mitigate the pathological case described. Another option would be to suck it up and compact it (at least partially) if the utilization fraction got too low. In extremis only attempting to do so when an out of memory error would otherwise occur, but would still generate large amounts of flack for making the poor management visible. "My app gobbled xGB of unused ram before releasing 99% of it." This would also be impractical if running x64 code because of the larger address space.

Hi I have application in c# that import dll writing in c++

The interface to the dll is
struct sNDIS_802_16E_CAPABILITY;
...
‘bool::WiMAXGetCapabilites(sNDIS_802_16E_CAPABILITY *pNDIS_802_16E_CAPABILITY)’

How can I send a pointer of the struct to the interface
Should I use ref?

Thanks
Ronen

I’m currently starting to work on internet apps, what i want to know is the "name" of such methods & what web hosting services i need.

Basically i want know how it’s called to do app communications using a webpage has the way to link them & start transmitting data.

Any examples or guides will be much appreciated 2 Smile | :)

Last time I checked there were over 110,000 methods in the .NET framework. You might like to narrow down what you'd like it to do.

I have no idea - It depends on what you want to do and what your budget is.

Isn't that the definition of a website: An applications that does communications.

Ok i think i missed this, what i want do is this:

Application A: User, Client, this app will be the one distributed & will ask App B for strings
Application B: The app that is contacted using the webpage url instead of an IP, Server, this app will create a connection to the App A & send back some strings.

Basically i just want to do strings communications using a webpage url to make the Apps to make a link & comunicate.

btw im not used to web/network apps, where do i start?

Your server connects to the clients? Normally the client connects to the server. Is there any particular reason for this?
