Use Resource File to Manage Strings for Multi-lingual Applications


By using resource file, strings used by controls or message windows can be converted to different language strings in your application. The VB 6 Resource Editor allows the addition of multi-tables for multi-lingual strings. Defined strings for corresponding language strings are usually stored in the resource file, and the correct language strings are automatically loaded by the LoadResString()statement.

There is an alternative way to achieve this. Instead of creating multi-tables, use only one default English table. Define multi segments in this table for multi-languages. For example, define 1-5000 for English, 5000-10000 for French, and 10000-15000 for Spanish. In the application, load a string from resource file like this:
 
    ' My Application Main Window
    frmMain.Caption = LoadResString(glLID + 10)

glLID is a global long variable that is defined by your application. Assign this variable at the start subroutine or add a language option in the application allowing users to choose. To make the code easy to read, I always add a comment with the string at the place where LoadResString() is used.

Use the Replace function to dynamically change strings when items in the string need to be replaced by certain value:
