gbal conversion hint

[9940]

Please, if a library can be released as GBAS, do so then, GBAL relies on the fact that the user can never alter it, that is, to add to its features, correct mistakes... so if the GBAL author is not available then the end user is screwed...

A gbal file is a normal gbas file with some garbage.
It can be rewritten:

0) Open the gbal file.
1) Take all cleary parts.
2) Add the gbal to a new glbasic blank project and compile it.
3) Open YourDrive:\Documents and Settings\YourName\Local Settings\glbasic\
WARNING: in v7 the gbal files are hidden and they get deleted after been compiled
4) Find the c++ conversion of the gbal
5) Now you have enough code to translate the gbal

Example
with ALWAYSONTOP(TRUE) (by unknown)

Take the cleary parts of the gbal

Code: GLBasic [Select]

INLINE
}
       extern "C" int __stdcall SetWindowPos(void*,d);
        namespace __GLBASIC__
{
ENDIN
FUNCTION ALWAYSONTOP: VALUE
//implemented pos and size for resolutions ;) -Hemlos
IF =FALSE THEN RETURN
LOCAL sx,sy,WinA
Y,InsertAfter Flagh
=-1; =18
GETSCREENSIZE //detect , YOU MUST HAV HWND()
0,0,sx+6,sy+33 d1D;
ENDFUNCTION
 

This is a bit useless.

Take the c++ conversion. (YourDrive:\Documents and Settings\YourName\Local Settings\glbasic\)

Code: GLBasic [Select]

#include "gpc_temp.h"
namespace __GLBASIC__{

/* ---- INLINE ---- */
}
       extern "C" int __stdcall SetWindowPos(void*, int, int, int, int, int, int);
        namespace __GLBASIC__
{

/* ---- ENDINLINE ---- */
// ------------------------ //
DGInt ALWAYSONTOP(DGInt VALUE)
{
   __PPRegisterFunction
//implemented pos and size for all resolutions ;) -Hemlos.
if (VALUE==FALSE )
return 0; // RETURN f. SUB
REGISTER_VAR_DEF(DGInt, sx, 0);
REGISTER_VAR_DEF(DGInt, sy, 0);
REGISTER_VAR_DEF(DGInt, WinPosX, 0);
REGISTER_VAR_DEF(DGInt, WinPosY, 0);
REGISTER_VAR_DEF(DGInt, InsertAfter, 0);
REGISTER_VAR_DEF(DGInt, InsertFlag, 0);
InsertAfter=-1;
InsertFlag=18;
GETSCREENSIZE( sx,sy);
//detect window size, YOU MUST HAVE THIS!.

/* ---- INLINE ---- */
SetWindowPos(GLBASIC_HWND(),InsertAfter,0,0,sx+6,sy+33,InsertFlag);

/* ---- ENDINLINE ---- */
return 0;
}
} // namespace

 

This is useful.

Let's translate to GLBasic

Code: GLBasic [Select]

INLINE
}
       extern "C" int __stdcall SetWindowPos(void*, int, int, int, int, int, int);
        namespace __GLBASIC__
{
ENDINLINE

FUNCTION ALWAYSONTOP: VALUE
        //implemented pos and size for all resolutions ;) -Hemlos.
        IF VALUE==FALSE THEN RETURN
        LOCAL sx,sy,WinPosX,WinPosY,InsertAfter,InsertFlag
        InsertAfter=-1
        InsertFlag=18
        GETSCREENSIZE sx,sy
        //detect window size, YOU MUST HAVE THIS!.
        INLINE
                SetWindowPos(GLBASIC_HWND(),InsertAfter,0,0,sx+6,sy+33,InsertFlag);
        ENDINLINE
ENDFUNCTION

Oh you <think of what you are>!

Yes, there is a slight problem with secutrity. But one thing, all comments are removed. Second, all global variables are removed. Third, the file usually gets deleted quickly after the compile.

I don't know how to protect them better, because that's the only way to make them cross platform.

I think of a better protection for version 7.

Think about the c\c++, you've never seen one obfuscated c++ file?

Except these

However the answer is no. The only way to to this is using the dll...
Any other way is vain, because you can go back to the original code.

I was told using an object file is possible as an alternative.
Is an object file as secure as a dll?
Do you know how to convert a gbas, cpp, or gbal into an object or dll files ?

[Schranz0r]

With the magic line: EXPORT functionname
An compile on GLBasic to DLL

[Hemlos]

That would be special requests for another thread ;{

[Schranz0r]

hehe

[Hemlos]

Ok im waiting on documentation for export, its not in the help file.
And i am definetly too stupid to figgure it out on my own hehehe

[Schranz0r]

GBAS:

Code: GLBasic [Select]

EXPORT Do_Something

WHILE TRUE



SHOWSCREEN
WEND
END

FUNCTION Do_Something: val1, val2
    RETURN val1+val2
ENDFUNCTION



 

SHIFT+F8 and compile as Win32_dll


Thats the trick

[Hemlos]

Ouch, not working.

Both with and without inputs does the same thing:

Have you gotten this to work ?

Does the german version have a help file for this?

compiling:

Oh dear. On my Todo now...
