Hi with this SetFixedCols, if I give a column no 3 then all columns from 0 to 3 are fixed.
I want to disable only 3rd column.
Is there any way to do it!

Sunil Kumar

How can I retrieve the domain name of a computer programatically.
In XP systems, the domain could be seen when
your right click 'My Computer' -> Computer Name (tab) -> Domain (Field)
Enumerating all the domains available would be even better/helpful.
Thanks in Advance

I hope GetComputerNameEx() would help you.

I have created a mfc application with vs2008 Pro. I have included a dockable pane ( all standard from the wizard). I created a dialog and would now like to write to the dockable pane from the dialog.
When I try to access it I get "cannot access protected member" is it possible to write to these windows from a dialog ? and if so does anyone know how.
I have tried so many things the one I am trying to write to is
"COutputList m_wndOutputBuild" created in the standard OutputWnd.h file created by the wizard.

You can provide an accessor function to get to that object and then call appropriate methods on it to write to output pane. Should be simple enough.
For e.g. a method like
GetOutputPane().Write( "Hello testing output pane" );
Hope I understood your question!

When I install vs2005 in vc++ directory setting I found
$(VCInstallDir)PlatformSDK\bin
$(VSInstallDir)Common7\Tools\bin
but in environment variable i could not found value of
$(VCInstallDir) and $(VSInstallDir) .
so where i found them I want to change them

 Why would you like to change them ? That's crazy. If you would do so, a lot of stuff wouldn't work anymore. Keep in mind that if you change those environment variables, it doesn't change the physical location of the install directory. So, all your header files and libraries won't be located anymore.
Why would you like to do such a thing ? What is the problem ?

actually I want to know where these variables store .I didnt find in
environmental variables list. Also I want to set my own. can u guide me , how to achieve this.

Hai,
i am having a doubt..
When to use pointers and references..?
Please tell me the scenarios...
Thanks,

This[^] should give you some idea.
Somethings seem HARD to do, until we know how to do them.

I think both servers the same purpose. But, usually References are preferred over pointers as the reference can not be a NULL as like pointers. In some scenario pointers are the only solutions. Like the function which returns the object or NULL (specifying failure).
But pointer isn't alternate solution for reference. Because you must have to make use of references while overloading an operator or providing an explicit copy constructor.

Additional to the links from the previous posters....
Rule of thumb: Use references when ever possible, pointers when necessary.

Hi All,
I am using the function unbuffered(int) in my project in VC 6.0 but when i compiled in .Net it is showing error saying that it is an undeclared identifier. This was inlcuded in the header Streamb.h in VC6.
But I couldn't find the header in VC++.Net. May I know whether this function has been taken out in .Net or is there any equallent function for the same?
thanks and regards,
Rajesh

Hi all
I have an assignment where I have to implement the abstract data type (ADT) Set which defines a set.
The following applies to sets:
• There must only be one occurrence of each element in the set (no duplicates allowed)
• The elements in the set are not ordered (they are not in a particular order)
• The union of two sets A and B (A U B) results in a new set containing the same elements as in A and also the element that are in B, but no duplicates.
• The difference between two sets A and B (A - B) results in a new set containing the elements that are in A but not on B.
•The intersection of the sets A and B produces a new set which contains all the elements that are equal in sets A and B.
The set is described by:
template <class t="">;
class Set
{
private:
class Node
{
public:
T data;
Node *next;
Node(T data) { this->;data = data; this->;next = NULL;}
~Node(){}
};
Node *first;
int nrOfNodes;
public:
Set();
Set(const Set<t>& set);
virtual ~Set();
void insert(T item);
T remove(T item); // returnerar det element som tas bort
bool isMember(const T& item) const;
int size() const;
Set<t> operator=(const Set<t>& set);
Set<t> operator+(const Set<t>& set) const; // union
Set<t> operator-(const Set<t>& set) const; // differense
Set<t> operator*(const Set<t>& set) const; // snitt
};
The storage structure for the set is a single-linked circular list (the next-pointer of the last element points at the first element).
I have created some empty functions for far for easy compiling,
//search
template <class t="">
bool Set<t>::isMember(const T& item) const
{
// return index if found or -1 if not found
Node* p;
int count = 0;
for (p = front; p != NULL; p = p->link)
{
if (p->data == item)
{
return true;
}
count++;
}
return false;
}
//add
template <class t="">
void Set<t>::insert(T item)
{
}
//remove
template <class t="">
T Set<t>::remove(T item)
{
}
//Display
template <class t="">
void Set<t>::display()
{
Node *q;
for( q = first ; q != NULL ; q = q->next )
cout<<q->data<<", ";
}
void main()
{
Set<int> SetA(10), SetB(10);
Set mySet(SetA);
}
When I compiled I get the following errors
cannot convert parameter 1 from 'int' to 'const Set<T> &'
with
[
T=int
]
Reason: cannot convert from 'int' to 'const Set<T>'
with
[
T=int
]
No constructor could take the source type, or constructor overload resolution was ambiguous
d:\visualprogrammes\linkedlist\linkedlist\linked_list.cpp(73) : error C2514: 'Set' : class has no constructors
d:\visualprogrammes\linkedlist\linkedlist\linked_list.cpp(6) : see declaration of 'Set'
Can someone please help, I can't see why the code in the main can't compile.
Thank you!

You'll have to define a parameterized constructor (that takes int parameter) for the class Set. And I wonder what you're trying to achieve by passing int parameter to Set class i.e. are you passing the size (10 items) or data (element) for the set. You'll have to code the parameterized constructor according the functionality required.
