在桌面上，鼠标左键双击程序，在打开的VB6主界面上，左边是工具菜单栏，单击标签按钮，在Form1窗口上，绘制出一Label1，然后在其属性窗口上改个名字，如Caption为第一数，如下图所示。
接着，用同样的方法，在Form1窗口上绘制出第二数，并且在左边工具菜单栏，单击文本框按钮，并绘制出来。在文本框属性栏的Text属性上，将其Text1删除，也就是清空数据，如下图所示。
然后，反复用第一步骤和第二步骤做成如图所示的界面来，学习需要反复练习，在练习中不断进步。这里是做简单的加法程序，如下图所示。
接着，加法程序的界面做好后，还不能执行加法运算，必须还要在Form1窗口上绘制出一个命令按钮来，在左边工具菜单栏，单击命令按钮，并绘制出来。然后给其属性窗口下Caption改名为计算，如下图所示。
然后，程序看起来是做好了，单击如图所示的运行按钮，d出自己做出的Form1窗口，输入数字3和6，然后单击计算。可是结果并没有出现，如下图所示。
最后，前面5个步骤只是做了程序的界面，想要程序出结果，那必须加些代码了，既然是简单程序，只加一行代码就可以了。双击命令按钮，在代码窗口中输入如下：Text3.Text = Val(Text1.Text) + Val(Text2.Text)后，再单击运行，输入数字，单击计算，此时就出现结果了，如下图所示。
