added QueryRawValue() to wxRegKey and test code for it in the sample

[wxWidgets.git] / distrib / msw / splitwise.cpp

///////////////////////////////////////////////////////////////////////////////
// Name:        splitwise.cpp
// Purpose:     Use this to split wxwin2.wse in the distrib/msw directory
//              into wisetop.txt, wisebott.txt. This allows you to do the
//              following:
//
//              1) Edit the existing wxwin2.wse in WISE Install.
//              2) Call splitwise.exe to split off the non-file bits (i.e.
//                 preserve everything except the "item: Install File" lines).
//              3) Call makewise.bat to generate a new wxwin2.wse from
//                 wisetop.txt, wisebott.txt and the file list generated
//                 from the files in deliver\wx (which themselves have been
//                 put there by zipdist.bat).
//
//              If you don't wish to change the WISE settings, then there's no
//              need to use splitwise, but it's very likely that settings will
//              be altered, e.g. to change the version number, what's installed,
//              etc.
