v1.12

Use GPadNT31.exe for all windows versions since Windows NT 3.1 (No Japanese interface)
Use GreenPad.exe for all windows versions since NT3.50.
And Use GPad64 if you have a 64 bits version of Windows.
Keep chardet.dll in GreenPad's directory for the best automatic encoding detection.
On Windows XP and later chardet.dll is not very useful and can be omitted.
On for x64 build chardet.dll is not used because I can only build an i386 version of chardet for now.
unicows.dll is only useful for Win9x, if you have not already installed it.

• Fixed huge crash, regression in 1.11 when disabling word wrapping.
• Fixed crash caused by MRU on some saved paths (1.10 regression).
• Improved unicode support (thanks to @rotyam1)
• Added a bunch of codepage to the list (rotyam1)
• Include latest revision of chardet.dll (rotyam1)
• Statusbar should work on buil 711 of NT3.5 (rotyam1)

TODO:

• Add a way to select codepage by number directly.
• Add UAC support for Windows Vista/7/8.X/10/11.
• Find/Replace only in the selection (if any).
• Improve printer configuration.
• Fix more bugs, handle low memory situations better.
• Ensure size_t is used over uint where applicable for x64 builds.
• Optimize memory usage so that larger files can be loaded.

GreenPad 1.11

Christmas release!

Well now it is much better, you even got the statusbar on NT3.1, you no longer
need to upgrade your comctl32 on Win95 and now IMM32 is dynamically imported
at runtime. This means that the NT3.1 build is now the ULTIMATE BUILD.
It runs on all windows version and does not sacrifice any features on newer
windows. The only reason there are two builds is for aesthetic reasons and
for the partial Japanese support possible on NT3.50+

• If available the IMM32.DLL will be loaded (advanced text services/IME).
• Thanks to @roytam1, it is now possible to have the statusbar on
  Windows NT3.1, also the "no text display bug" on windows 95 is fixed.
• Added the /LARGEADDRESSAWARE linker flag to permit up to 4GB ram usage
  when running GreenPad under 64bit edition of Windows.
• Now the main window is showed before loading the file.
• Smart indentation supported: keeps indentation level on Return.
• Added Tab/Shift+Tab to indent/un-indent a multi-line selection.
• Fix mingw64 builds and provide x64 builds of GreenPad.
• Fix IID_IMultiLanguage2 definition for encoding auto-detection.
  You no longer need chardet.dll on newer Windows versions.

TODO:

• Add UAC support for Windows Vista/7/8.X/10/11
• Find/Replace only in the selection (if any).
• Improve printer configuration.
• Fix more bugs, handle low memory situations better
• Ensure size_t is used over uint where applicable for x64 builds.
• Optimize memory usage so that larger files can be loaded.

GreenPad 1.10

The purpose of this fork is to make the ultimate exe that will work on
all Windows versions NT3.1-->Win11 while still having MAXIMUM functionality
under later Windows versions, for now it is not far but I am not there yet...

For now you have two versions of GreenPad:
GreenPad.exe: English+Japaneese, NT3.5+ compatible version (needs IMM32.DLL)
GPadNT31.exe: English only NT3.1+ compatible version.

Note1: exe are not compressed (do it yourself if you like).
Note2: There is no Win32s builds yet but it may come at some point...
Note3: It seems paths longer than 259 char cannot be used on NT3.1 (no possible \?\ prefix).
Note4: Page setup dialog is not available on NT3.1/3.5 but you can set print margins in thousands of inches in the ini file via PMarginX with X=L,T,R,B (for left top, right, bottom) under your user config.

Changes

• Support for UNC path, you can edit files with a path longer than 260
  characters, only under Windows NT. Note that the shell is still
  limited to 260 char path so you can drag&drop long file path from
  double-commander or similar software, you can also use the command line.
  but it is not possible to use File->Open to open UNC. Blame Microsoft...
• Add Upper, Lower and Invert Case options that change the case of selected
  text. Use Alt+U/Alt+L/Alt+I, (like with Metapad).
• Add Trim trailing spaces option (Alt+W), like with Metapad.
• Added ESCAPE key to exit GreenPad.
• Added F12 key to be used for "Save As..", like in MS Office suite.
• Added F5 to refresh the file (keeps cursor position).
  Use F6 to insert Date&Time.
• Added new font control option to .lay files.
  • fx to set the width of the font in points (0 = normal)
  • fw to set the weight of the font (0 to 1000), 400=normal, 700=bold...
  • ff to set the 1:italic/2:underlined/4:strikeout font styles.
• The current font will be used for printing (ttf).
• File->Page Setup.. Was added so that print Margins can be selected.
• Fix High DPI issues under Win8.x/10/11 (dpi-aware manifest)
• Fix crash because of an oob access in ip_parse.c!!!
• Fix: Use PostMessage instead of SendMessage and avoid to freeze all
  instances of GreenPad when one stops responding.
• Use CreateWindow instead of CreateStatusWindow, so statubar can be
  included in WinNT3.1 (Needs COMCTL32 v3.5+ though).
• Dynamically import OLE32.dll so that it is detected at runtime instead
  of compile time (towards ultimate exe).
• Dynamically import CharNextExA, when using Win95+/NT4+ -> ultimate exe.
• Re-implement FindWindowEx function using EnumChildWindows for NT3.1.
  So that you can Use Ctrl+Tab there to switch between GreenPad windows.
• Dynamically import Get/SetScrollInfo for the best scroll support on
  Window NT3.51 and later and fallback to Get/SetScrollPos for NT3.1/3.5.
• New files can now be created from the Open dialog.
• Dynamically import GetKeyboardLayout --> ultimate exe.
• Dynamically import GetShortPathNameW (actually useless...).

TODO

• Add UAC support for Windows Vista/7/8.X/10/11
• Dynamically import IMM32.DLL --> Ultimate exe.
• Find/Replace only in the selection (if any).
• Smart indentation option
• Tab/Shift+Tab to indent/un-indent a block of text.
• Improve printer configuration.
