Set the Checked 163: // property of the menu item to the same value as WordWrap. 164: // 165: Memo->WordWrap = !Memo->WordWrap; 166: EditWordWrap->Checked = Memo->WordWrap; 167: // 168: // If WordWrap is on then we only need the vertical scroll 169: // bar. If it’s off, then we need both scroll bars. 170: // 171: if (Memo->WordWrap) Memo->ScrollBars = ssVertical; 172: else Memo->ScrollBars = ssBoth; 173: } 174: //------------------------------------------------------------ And Now, the Moment You’ve All Been Waiting For After you have created the event handlers for the menu items, you are ready to run the program. Click the Run button, and the program should compile and run. If you get compiler errors, carefully compare your source code with the code in Listing 7.2. Make any changes and click the Run button again. You might have to go through this process a few times before the program will compile and run. Eventually, though, it will run (I promise!). When the program runs you will find a program that, although not 100 percent featurecomplete yet, acts a lot like Windows Notepad. Although we have a few things to add before we’re finished, we have a pretty good start—especially when you consider the actual time involved up to this point. Figure 7.22 shows the ScratchPad program running. Figure 7.22. The ScratchPad program in action. 259 7
