The PrintTextString method is implemented by the subsequent steps. Note that our implementation prints the given string across multiple lines if necessary by drawing each word in the text string separately. Also note that the printArea variable is passed by reference. This is required in order to modify the printable area for text strings in the PrintTextString method. Since the RectangleF structure is a value type, it is normally passed by value.

Actually, the string class is a specialization of a more general template class called basic_string In fact, there are two specializations of basic_string: string, which supports 8-bit character strings, and wstring, which supports wide-character strings Since 8-bit characters are by far the most commonly used in normal programming, string is the version of basic_string examined here Before looking at the string class, it is important to understand why it is part of the C++ library Standard classes have not been casually added to C++ In fact, a significant amount of thought and debate has accompanied each new addition Given that C++ already contains some support for strings as null-terminated character arrays, it may at first seem that the inclusion of the string class is an exception to this rule However, this is actually far from the truth Here is why: Null-terminated strings cannot be manipulated by any of the standard C++ operators Nor can they take part in normal C++ expressions For example, consider this fragment

IMPLEMENT THE PRINTTEXTSTRING METHOD Action 10 Add a PrintTextString method to the MainForm.cs code window. Result

char s1[80], s2[80], s3[80]; s1 = "Alpha"; // can't do s2 = "Beta"; // can't do s3 = s1 + s2; // error, not allowed

.

protected void PrintTextString( Graphics g, Font printFont, string name, string text, ref RectangleF printArea) { // Establish some useful shortcuts float leftMargin = printArea.Left; float rightMargin = printArea.Right; float topMargin = printArea.Top; float bottomMargin = printArea.Bottom; float fontHeight = printFont.GetHeight(g); float xPos = printArea.Left; float yPos = topMargin + fontHeight; float spaceWidth = g.MeasureString(" ", printFont).Width; float nameWidth = g.MeasureString(name, printFont).Width; if (!printArea.Contains(xPos + nameWidth, yPos)) { // Does not fit, so abort return; }

As the comments show, in C++ it is not possible to use the assignment operator to give a character array a new value (except during initialization), nor is it possible to use the + operator to concatenate two strings These operations must be written using library functions, as shown here

strcpy(s1, strcpy(s2, strcpy(s3, strcat(s3, "Alpha"); "Beta"); s1); s2);

Create some local variables for the margins of the printable area. Also determine the height of the font and the coordinates where the text should be drawn. Find the width of a space and the name for the text string.
