CStringList class members

structure

Construct an empty CString The object list

First/last access

GetHead	Returns the header element in this list (which cannot be empty)
GetTail	Returns the trailing element in this list (which cannot be empty)

operation

RemoveHead	Remove the element from the head of the list
RemoveTail	Remove the element from the end of the list
AddHead	Adding an element to the head of a list (or all of the elements in another list) generates a new head
AddTail	Adding an element to the end of a list (or all of the elements in another list) generates a new tail
RemoveAll	Delete all elements in this list

repeat

GetHeadPosition	Returns the position of the header element in the list
GetTailPosition	Returns the position of the tail element in the list
GetNext	Gets the next element to repeat
GetPrev	Gets the previous element for repetition

Acquisition/modification

GetAt	Gets the element at the given location
SetAt	Sets the element at the given location
RemoveAt	Removes an element specified by location from this list

insert

InsertBefore	Inserts a new element before a given location
InsertAfter	Inserts a new element after a given location

Find	Gets the position of the element specified by the string value
FindIndex	Gets the location of the element specified by a zero-based index

state

GetCount	Returns the number of elements in this list
IsEmpty	Test if the list is empty (no elements)

CStringList is a CString linked list, an alternative to STL in MFC programming, and is more concise to use.

Insert data: AddTail (); AddHead ()

Remove data: RemoveAll(); RemoveAt (); RemoveHead (); RemoveTail ()

Get the number of elements: GetCount()

GetAt(cstringlist.findindex (index))//index is an integer

GetHead(); GetTail (),

The best way to do this is not to use the POSITION variable, but to use FindIndex.

Initialization:


CStringList listFileName;
listFileName.RemoveAll();

Add operation:


listFileName.AddTail(szFullPathName);

Traversal operation:


POSITION rPos;
rPos = listFileName.GetHeadPosition();
while (rPos != NULL)
{
strFileName = listFileName.GetNext(rPos);
strLog += "/r/n" + strFileName;
}
