// Add the column styles to the table style albumStyle.GridColumnStyles.AddRange( new DataGridColumnStyle[] { captionCol, validCol, dateCol, photographerCol, fileNameCol }); // Assign the table style to the data grid gridPhotoAlbum.TableStyles.Add(albumStyle); }

Let s look at this program carefully In main( ), a character vector called v is created with an initial capacity of 10 That is, v initially contains 10 elements This is confirmed by calling the size( ) member function Next, these 10 elements are initialized to the characters 'a' through 'j' and the contents of v are displayed Notice that the standard array subscripting notation is employed Next, 10 more elements are added to the end of v using the push_back( ) function This causes v to grow in order to accommodate the new elements As the output shows, its size after these additions is 20 Finally, the values of v s elements are altered using standard subscripting notation There is one other point of interest in this program Notice that the loops that display the contents of v use as their target value vsize( ) One of the advantages that vectors have over arrays is that it is possible to find the current size of a vector As you can imagine, this is quite useful in a variety of situations

This adds the new column styles to the existing table style object. When a data source of type PhotoAlbum is displayed, the new styles specify which columns should

.

As you know, arrays and pointers are tightly linked in C++ An array can be accessed either through subscripting or through a pointer The parallel to this in the STL is

appear and how they should look. For example, the column style based on the IsImageValid property is as follows:

the link between vectors and iterators You can access the members of a vector using subscripting or through the use of an iterator The following example shows how

// Access the elements of a vector through an iterator #include <iostream> #include <vector> #include <cctype> using namespace std; int main() { vector<char> v(10); // create a vector of length 10 vector<char>::iterator p; // create an iterator int i; // assign elements in vector a value p = vbegin(); i = 0; while(p != vend()) { *p = i + 'a'; p++; i++; } // display contents of vector cout << "Original contents:\n"; p = vbegin(); while(p != vend()) { cout << *p << " "; p++; } cout << "\n\n"; // change contents of vector p = vbegin(); while(p != vend()) { *p = toupper(*p); p++; } // display contents of vector cout << "Modified Contents:\n";

DataGridColumnStyle validCol = new DataGridBoolColumn(); validCol.MappingName = "IsImageValid"; validCol.HeaderText = "Valid "; validCol.ReadOnly = true; validCol.Width = 30;
