Exercises
1. Create a new application. Display the Project Manager. Click the Add Unit button
to add a new unit to the project. Navigate to the
\CBuilder\Examples\Apps\Contacts directory and choose the file called
Contacts.cpp. Click OK to add the file to the project.
2. Remove the Contacts.cpp unit from the project in Exercise 1.
3. Open the ScratchPad project. Change the main form to the AboutBox form. Close
the Project Options dialog box and run the program. The About box will be
displayed when the program starts. Close the About box to end the program and
change the main form back to the ScratchPad form.
4. Open the RichEdit application that is supplied with C++Builder. Go to the Project
Options dialog box and confirm that the Optimization setting on the C++ page is
set to Optimize for Speed. Do a Build All to build the program. Check the size of
the produced .exe. Go back to the Project Options dialog box and change the
optimization to Optimize for Size. Again do a Build All. Check the final .exe size
again to compare the difference. How much smaller or larger was the .exe when
the compiler optimized for size?
5. Open any source file in the Code Editor. Set four bookmarks at random locations
in the source file. Jump from bookmark to bookmark and observe the effects in the
Code Editor. When you are finished, clear all the bookmarks.
6. Open the ScratchPad project (or any other project) and switch to the Code Editor.
View the project’s main form source file. Choose Search | Find from the main
menu. Type Click in the Text To Find box and click OK to find the first occurrence
of the word Click.
7. Press F3 several times to repeat the search until the entire file has been searched.
