Adding an Application INI File to Registry

Applications can add their own INI file to registry by:

• Updating REGH_INIMAPPING: Add the name of the application INI file under REGH_INIMAPPING. For example, for application XYZ, create a new node under REGH_INIMAPPING called XYZ.INI. For each section in XYZ.INI, create a value under the XYZ.INI node. The value name is the section name. The value content is the corresponding directory path under the REGH_WINOS2INI node. See step 2.

• Updating REGH_WINOS2INI: Add the name of the application INI file under REGH_WINOS2INI. For example, for application XYZ, create a new node under REGH_WINOS2INI called XYZ.INI. Add a new node under XYZ.INI. The name of the node is the group name.

After completing these two steps, the application can use Windows 32-bit profile functions to modify the contents of XYZ.INI.

When finished, the registry structure looks like this:

winreg (root)  ---                  |
                  |-- REGH_WINOS2INI --- XYZ.INI
                  |
                                          |--section 1
                                          |
                                          |  (value name=key name 11;
                                          |   value content...)
                                          |   value name=key name 12;
                                          |   value content...)
                                          |
                                          |--section 2
                                          |
                                             (value name=key name 21;
                                              value content...)
                                              value name=key name 22;
                                              value content...)

                  |-- REGH_INIMAPPING
                        |--- XYZ.INI
                        (value name=section1;
                         value content="XYZ.INI\section1")
                        (value name=section2;
                         value content="XYZ.INI\section2")

All new keys added under HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS NT\CURRENTVERSION\INIFILEMAPPING are added to REGH_INIMAPPING.

All references to HKEY_LOCAL_MACHINE\SOFTWARE are mapped to REGH_WINOS2INI.
