This is a library designed to help C++ developers in creating Windows application to translate it on world languages. Project contains an utility to convert existing resources of application in PO-file and adds ability to use translated PO-files to application itself. The PO-file is a native format of poEdit (a very convenient application for translators).

Library can load translations in uncompressed or compressed formats (Lempel-Ziv algorithm only). Uncompressed files has ".po" extension and compressed ones has ".p_" extension. Compressed files can be produced by Microsoft File Compression Utility named "compress.exe". It can be found in any old Microsoft OS or Resource Kit. Usage example:

compress.exe you_application.exe.09.po you_application.exe.09.p_

Compressed files can be also inserted as resources (detected by magic number 'SZDD' at beginning of file).

Library uses WinAPI LZExpand library (Lz32.dll) to handle compressed files.

Note: Some versions of compress.exe produces incorrect compressed files (1 byte differ) just get another version of utility.

exe2po.exe {input file.exe} {output file.po}

NOTE: You can ease converter usage by dropping exe2po.exe to Windows folder and registering "Create PO" context menu by merging with "exe2po-register.reg" file (undo with "exe2po-unregister.reg" file).

Generated .po-file blocks for menu resources:

#: MENUPOPUP.{menu-id}.{ordinal}
msgid "English menu popup"
msgstr ""

#: MENUITEM.{menu-id}.{menu-item-id}
msgid "English menu item"
msgstr ""

Where {ordinal} is a number 0, 1, 2 etc.

Generated .po-file blocks for dialog box resources:

#: DIALOGCAPTION.{dialog-id}
msgid "English dialog caption"
msgstr ""

#: DIALOGCONTROL.{dialog-id}.{control-class}.{dialog-control-id}
msgid "English dialog control"
msgstr ""

Where {control-class} is a "Button", "Static" etc. If dialog control id is a 0xffff then {dialog-control-id} = ( 0x80000000 | ordinal ) where ordinal is a number 0, 1, 2 etc.

Generated .po-file blocks for string resources:

#: STRING.{string-id}
msgid "English string"
msgstr ""
