Steps to install and test the DBD DLL with Visual C++.
1. Download DLL appropriate for your OS and save in C:\Temp\Test directory.
2. Expand dll.zip.
3. Run Microsoft VC++
4. From menu File > New, select "Win32 Console Application" in Projects Tab.
Set Project name to "Test".
Set location to "C:\Temp\Test".
Click OK.
5. Select "A simple application" and click Finish.
6. Copy dbd.dll, dbd.lib and dbd.h into C:\Temp\Test
7. Update your Test.cpp to be similar (if not equivalent) to that shown below.
8. For Windows NT, 2000 and XP environments, from MS VC++'s menu > Project > Setting > C/C++ Tab > In 'Preprocessor definitions' text box, remove "_MBCS" add "UNICODE,_UNICODE" and click OK.

10. In Workspace Window which list project files, in File View Tab, right-click 'Header Files' Folder select 'Add Files to Folder'. In dialog box, select dbd.h and click OK.
11. Build project.
12. Single-step (F10) thru code and verify error codes returned by functions are 0.
Single-step thru code three more times to execute all sections.
13. Exit VC++.
14. Verify data in C:\Temp\Test\Db1.dbd with dbd.exe
15. To uninstall, delete folder C:\Temp\Test
