How to translate catalog from MUIBuilder into your prefered language ? Very easy !!! Just rename 'OtherLanguage.ct' to 'XXXXXX.ct' ( XXXXXX is your language name ). Then translate the english sentences to the new ones. You just have to know, how the hotkeys are coded : ; ; This is message number one MSG_message_number_one(//) This is the first message ; ; This is the hotkey of the message number one ! MSG_message_number_oneKey(/1/1) t here : t is the hot-key of 'This is a message' ! When the translation is finished, you just have to build the catalog file using Catcomp or Flexcat ( for example ): With Catcomp, just type in a shell : > Catcomp MUIBuilder.cd XXXXXXXXX.ct CATALOG MUIBuilder.catalog > copy MUIBuilder.catalog locale:catalogs/XXXXXXXX With Flexcat : > Flexcat MUIBuilder.cd XXXXXXXXX.ct CATALOG MUIBuilder.catalog > copy MUIBuilder.catalog locale:catalogs/XXXXXXXX The most difficult task in this translation is to pay attention to the hotkeys : it's very easy to have twice the same hotkey in a window ... If you want to make a translation in your language, and succeed in this task .... PLEASE .... Send it to me !!! ... Thanks ... Eric.
