Spreadsheet viewer for tab-separated values (*.TSV or *.TAB) files

[jj2007]

A little project inspired by Timo on the Pelles C Forum.

It reads in comma- or tab-separated values and displays them in a SysListView32. Content can be sorted by column, and since the underlying sort algo is stable, you can even sort by multiple columns (which finally explains my interest in fast stable sorts  ).

For a real life test, click "Download database" in the File menu. In case you want to find that part in the source, here it is:

 case IdMenuDL
  MsgBox 0, "Retrieve a 10 MB database for testing?", "Download:", MB_OKCANCEL
  .if eax==IDOK
            UnzipInit "http://www.thisisprivatefolks/SomeDatabase.zip"
            .if Sign?
                  MsgBox 0, "Download failed, sorry", 0, MB_OK
            .else
                  Let LvFile$="MDG_Database.csv"
                  FileWrite LvFile$, UnzipFile(0)
                  UnzipExit
                  call LoadDatabase
            .endif
  .endif

Feedback welcome - requires MasmBasic version 28 May or later.

EDIT: Version 2 attached, fixes a bug with the status bar, plus this one:
You can delete columns using the LVM_DELETECOLUMN message. There's no way to delete them all at once; you need to do them one by one.

Version 3 fixes an odd bug that crept in when building the tinf library: tinf.lib was built with SubSystem Console - and all code linked to it suddenly had a console window :(
