This question should be posted in the Visual C++[^] forum. This is the C++/CLI forum that's dedicated to the new managed and mixed-mode compiler available in VC++ 2005.

it's very embarrasing to see how many people make the confusion... when one have to ask for a managed C++ question, i think they see the name Visual C++ forum and in their head, the idea goes quickly into, "hummm, managed code is a microsoft thing, so i think that the Visual C++ forum is for me" (as Visual stands in a certain way for microsoft products)...
in the other hand, when one have to ask for pure C++ question, i believe that what come to them is something like "hmm, C++/CLI is the right forum to go as it stands for C++, and CLI, i don't know what it is, but it might me related to the standard... whatever, i ask this here".

i wonder if the CLI forum got back its old name "Managed C++" forum people still got confused... WTF | :WTF:

you post 4 messages out of 5 to say to people they write the wrong forum Cry | :((

Yeah, the naming scheme Microsoft chose is probably a little confusing, but I also think people are pretty careless about where they post. Perhaps a stickey thread on top that explains what this forum is for would be useful in reducing the number of mis-postings.

I need to modify CxImage library function to include CArray as a parameter.
I have no clue how to include reference to afxtempl.h in this libraray.
Using VC 6.0 and MFC.
Thanks for your help.

Hello Vaclav, there is no CxImage class in MFC. It looks like you are using a 3rd party library - it's best to contact their tech support.

On the other hand, if you are talking about Davide Pizzolato's class, ask this question in the article forum.

Since Davide no longer "supports" his article I felt I had a better chance here.
I guess I am looking for a generic advice how to add or put together different libraries.

Please help me with this:

int SetArray(array <String ^> ^str)
{
	str = gcnew array <String ^> (5);	// Quick Watch for str: {Length=5}
	return 0;
}

int main(array<System::String ^> ^args)
{
	array <String ^> ^str;
    SetArray(str);
	Console::WriteLine(str);	// Quick Watch for str: <undefined value> and i need to act like in Win32 in, out pointer
    return 0;
}

Thanks in Advance.

Change your SetArray prototype to :-

int SetArray(array <String ^>^% str)

Notice the extra %.

Instantiate a new font object? Or create a totally new font object in-memory? The former is possible and easy. The latter would be a pretty complex process, and why would you want to do that?

you can take data in a variable by cin

and print that data to output stream by cout.

or

u can use file opration for it.

Create file,write data to file and finaly read data from file. Big Grin | :-D

Note that the samples are in C# and VB, but it's trivial to convert that to C++/CLI.

Re: Question on Hashtables

Question on Hashtables

jblau5-Jan-06 17:43

jblau

5-Jan-06 17:43

My understanding of Hashtables is this: If I declare a Hashtable like so: Hashtable *hashMyHashtable = new Hashtable; I don't need to have a corresponding DELETE after having used the NEW for the Hashtable. The reason being that the Hashtable is a Managed object and so I don't need to Delete it in my destructor.

My question is this: If I store an object that was declared with a NEW, and store it in the hashtable, do I need to go back through the hashtable and delete those objects, or does the managed code do that as well?

Example:
MyObject *tempObject = new MyObject;
Hashtable *hashObjects = new Hashtable;

hashObjects->Add(key, tempObject);

So if I store several tempObjects in my hashtable, do I need to traverse through the hashtable and DELETE the tempObjects, or does the garbage collector handle this as well as the hashtable itself?

If I do need to delete them, will a call to hashObjects->clear(); delete the objects?

Thanks,

The correct way to work with managed objects in C++/CLI is to use managed references, and the gcnew operator.

//note the "^", which denotes a managed reference, just as a "*" denotes a pointer,
//and the use of the gcnew operator to instantiate the objects on the managed heap.
MyObject^ tempObject = gcnew MyObject();
Hashtable^ hashObjects = gcnew Hashtable();

hashObjects->Add(key, tempObject);

Once all references to a managed object are set to null or go out of scope, the object will be garbage collected at whatever point the CLR decides to do so.
