VS 2008 - Multilingual Support - From VB6

I am currently working on converting an app from VB6 to VB.NET 2.0 - I am only using 2.0 to provide Win 2k compatibility, AFAIK, Win 2k can't run any framework newer then 2.0. Part of the conversion includes moving multilingual support over. In the VB6 version, we were storing the translated text in an Excel document - the xls could be passed to translators. A script in the xls file would dump the languages to individual text files and generate a LanguageRescource.rc file which was then compiled using RC.exe.

When the app started or the user selected a language, the resource file was read using:

Public Sub LoadLang(ByVal LangNum As Byte)
Dim bData() As Byte

[CODE]...

It was then split using vbNewLine as a delimiter and the lines assigned to the labels and to a public array for use in other places in the program (message boxes, log files, etc). Doing the same thing in .NET doesn't seem possible, or is rather convoluted. I have read many articles on globalisation, localisation, etc and it doesn't make a whole lot of sense to me. I am wanting to have the language files built in to the executable, not as dependencies. From what I can tell after reading all of this information is there are at least 2, if not more to do it.

1) Use form localisation. This would require changing all the captions and things for each language, this would in turn generate frmMain.<lang>.resx files.

The correct file would be loaded automatically on form/program startup and is hard to change at runtime if the user wishes. it would also cost me a fair bit of time to add every one of the 23 languages. It also would not satisfy my other requirements of message boxes and output to log files.

2) Make a resource file and store the strings in there, in a similar fashion to what I was doing in VB6. The problem is, how do I separate each languages strings? Each resx file only seems to be capable of storing on string table.
