Visual Basic 6 Strength

One of the greatest strengths of the Visual Basic language is that programmers can design an application and then test it without leaving the environment. But you should be aware that designing and testing a program are two completely different tasks. At design time, you create your forms and other visible objects, set their properties, and write code in their event procedures. Conversely, at run time you monitor the effects of your programming efforts: What you see on your screen is, more or less, what your end users will see. At run time, you can't invoke the form designer, and you have only a limited ability to modify the code you have written at design time. For instance, you can modify existing statements and add new ones, but you can't add new procedures, forms, or controls. On the other hand, at run time you can use some diagnostic tools that aren't available at design time because they would make no sense in that context (for example, the Locals, the Watches, and the Call Stack windows
