    So ,this news is ok.
    But still if i wanna write modul i must
    use Power Basic for this job.
    Best option will be if is posibile that
    we can make write modules with
    thinBasic like is posibile in DLib.
    In DLib are called userLibs...
    What you say about that?

    Well, I do not know DLib. As far as I can see many people loved it but actually it seems an abandoned project.
    thinBasic is not a compiler so it cannot create any library.

    In any case wait till I will release firt thinBasic version having the new class module classes inside.
    Than we will see

    Eros DLib is not compiler it is interpreter

    thats all.
    OK i will wait...

    An interpreter cannot create runtime libraries (DLLs). Is like asking a car to fly: you need a plane.
    An interpreted can emit code (converting from its native syntax to other languages that can compile) into a different language that can compile. Many so called "compiler" are in reality code emitters (translators) into some ASM language. Than ASM is used to compile on the fly.

    But because I'm curious and I always try to learn something new, I just read about those "UserLibs" to get the idea about them. Downloaded DLib, red help, binary inspected such files. It seems that such files (.DCS) are just a collection of DLib source code made available as compressed (maybe encrypted) way. So such files are mainly like include files.
    The idea is not bad but you can create that kind of files only starting from DLib native language functionalities. You create some functions and say to DLib to make available as compressed/encrypted. They are not compiled at all. In few words it is just source code you cannot read.

    What I'm doing to do here is something completely different because I'm changing the heart of thinBasic Core engine.

    hello eros, zlatko. I am just looking for a simple in freebasic written ( module ) example. there are any example for it? thanks, largo
    new edit: solved! found sdk folder with pb/fb files.

    I am curious to see new module functions to create with thinbasic.

    Starting from thinBasic version 1.8.8.0 module classes are a reality.
    First module class developed is called cTimer and is native in thinBasic Core module, so available in every script.
    Full documentation in thinBasic help file.
    This is just a starter in order to test all possible aspects of this implementation.

    %thinBasic_ReturnNone             =  &h0 %thinBasic_ReturnCodeByte         =  &h1 %thinBasic_ReturnCodeInteger      =  &h2 %thinBasic_ReturnCodeWord         =  &h3 %thinBasic_ReturnCodeDWord        =  &h4 %thinBasic_ReturnCodeLong         =  &h5 %thinBasic_ReturnCodeQuad         =  &h6 %thinBasic_ReturnCodeSingle       =  &h7 %thinBasic_ReturnCodeDouble       =  &h8 %thinBasic_ReturnCodeCurrency     =  &h9 %thinBasic_ReturnCodeExt          = &h10 %thinBasic_ReturnNumber           = &h20 %thinBasic_ReturnString           = &h30  Declare Function FunctionGetPtr Lib "thinCore.dll" Alias "thinBasic_FunctionGetPtr" (ByVal fName As String) As Long Declare Function thinBasic_LoadSymbol Lib "thinCore.dll" Alias "thinBasic_LoadSymbol" (ByVal SymbolName As String, ByVal ReturnCode As Long, ByVal FunctionOrSubPointer As Dword, Optional ByVal ForceOverWrite As Long) As Long Declare Function thinBasic_Class_Add Lib "thinCore.dll" Alias "thinBasic_Class_Add" (ByVal sClassName As String, ByVal pClassFunc As Long) As Long Declare Function thinBasic_Class_AddMethod Lib "thinCore.dll" Alias "thinBasic_Class_AddMethod" (ByVal pClass As Long, ByVal sMethodName As String, ByVal MethodReturnType As Long, ByVal pMethodFunc As Long) As Long  Local RetCode As Long  TYPE IrrlichtDevice DWORD 	run As Long END TYPE  Local IrrlichtDevicePtr As Long = thinBasic_Class_Add("IrrlichtDevice", Function_GetPtr(IrrlichtDevice_run)) If IrrlichtDevicePtr Then 	RetCode = thinBasic_Class_AddMethod(IrrlichtDevicePtr, "run", %thinBasic_ReturnNumber, Function_GetPtr(IrrlichtDevice_run)) 	RetCode = thinBasic_Class_AddMethod(IrrlichtDevicePtr, "getVersion", %thinBasic_ReturnString, Function_GetPtr(IrrlichtDevice_getVersion)) Else 	Uses "console" 	PrintL "ERROR thinBasic_Class_Add IrrlichtDevice" End If
    
    I'm trying to do so and it might work, but is not suitable for Function_GetPtr code (and TYPE are also under suspicion). Here is the correct function for passing a pointer?
