the label.) The error handler routine continues through the Resume ClearInput statement. If a type-5 error is encountered (because b2 < 4ac), the error message shown in Fig. 6.26 is displayed. (Note that the test is based upon the value assigned to the Number property of the system-defined error object Err.)

Clicking on OK causes the input data fields to be cleared, so that a new dataset may be entered without shutting down and then restarting the program. If the user specifies a = 0 but b > 0 as input parameters, the program will experience a division by zero when attempting to calculate the values of x1 and x2. Visual Basic recognizes this particular calculation as an overflow rather than an explicit division by zero, because the numerator and denominator are expressions rather than single quantities. Thus, to be on the safe side, the error trap tests for both conditions an overflow (Err.Number = 6), and an explicit division by zero (Err.Number = 11). In either case, the error message shown in Fig. 6.27 is displayed. The input data fields will be cleared when the user clicks on OK, as with the type-5 error.

Returning to the Visual Basic code, notice that the error handler ends with the Resume ClearInput statement. This statement not really necessary in this case, since the program logic would automatically drop down into the succeeding statements that clear the input data upon completion of the error handler. However, it is good programming practice to include the Resume ClearInput statement, since some intervening statements (between the error handler and the clear input statements) may be added at some future time. Hence, it is included here as a matter of good programming practice. Notice also that the error handler does not account for the situation b2 = 4ac. (as, for example, is encountered when a = 2, b = 4, and c = 2). This condition does not produce a computational error, but does result in identical values of x1 and x2, since there is only one real root when b2 = 4ac. The code can easily be modified to recognize this situation and display an appropriate message. This modification is left to the reader as a programming exercise (see Prob. 6.54).

6.8 GENERATING A STAND-ALONE EXECUTABLE PROGRAM Once your program has been debugged, you may want to generate a separate, stand-alone version. Stand-alone programs are convenient because they can be run independently of the Visual Basic development system, and they can easily be transported from one computer to another. On the other hand, they cannot be edited, and the interactive debugger is not available in the event of an execution error. Generating a stand-alone executable program is easily carried out. Simply select Make from the File menu within the Visual Basic environment. Then provide the name of the executable file (typically, the same name as the source file) and click the OK button. This will result in a new file with the given name and the extension .exe. The new file, name.exe, can then be moved out of the Visual Basic system or moved to a different computer, and then executed on its own.

EXAMPLE 6.4 GENERATING A STAND-ALONE EXECUTABLE PROGRAM
Suppose we wish to generate an independent, stand-alone version of the quadratic equation program presented in Example 6.3. We will save this program with the name QuadraticEqns.exe. To accomplish this, we open the desired project within the Visual Basic Environment and then select Make Ex6.3 from the File menu, as shown in Fig. 6.28. Note that the default file name is Ex6-3.exe, which is taken from the name of the current Visual Basic project (Ex6-3.vbp).
