RE: Using LUA directly from the DLL

["Alexander Altshuler" <alt@...>]

IMHO, it is possible to run Lua script from VB.
For example:

======8<================================
Declare Function lua_newstate Lib "lua51.dll" ( ByVal f As Long, ByVal
ud As Long ) As Long
Declare Sub luaL_openlibs  Lib "lua51.dll" ( ByVal L As ong )
Declare Function luaL_loadfile Lib "lua51.dll" ( ByVal L As Long, ByVal
filename As String ) As Long
Decalare Function lua_pcall Lib "lua51.dll" ( ByVaL L As Long, ByVal
nargs As Long, ByVal nresults As Long, ByVal errfunc As Long ) As Long
Declare Sub lia_close Lib "lua51.dll" ( ByVal L As Long )

Dim L as Long
L = lua_newstate( 0,0 )
luaL_openlibs( L )
Dim ok as Long
ok = luaL_loadfile( L, "myfile.lua" )
If ok Then
   Lua_pcall( L, 0, -1, 0 )
End If
Lua_close( L )
======8<================================

Code above is never tested!
Last time I wrote for VB dialect (Lotus Script) 6 yeas ago.

What can you do with your development platform if you cannot compile C
code and cannot execute precompiled lua.exe file ? How can you access
a DLL otherwise ?
