Hi all,
I need your help.
I want to create a DLL designed by PB5.11
(I want to use 4 instructions from PB5.11 in PB6.00+)
Here is the code I enter in PB5.11:
Code: Select all
ProcedureDLL.q DSolidSprite(Sprite,x,y,Couleur):DisplaySolidSprite(Sprite,x,y,Couleur):EndProcedure
ProcedureDLL.q DShadowSprite(Sprite,x,y):DisplayShadowSprite(Sprite,x,y):EndProcedure
ProcedureDLL.q DTranslucentSprite(Sprite,x,y,Intensity):DisplayTranslucentSprite(Sprite,x,y,Intensity):EndProcedure
ProcedureDLL.q DRGBFilter(x,y,w,h,r,g,b):DisplayRGBFilter(x,y,w,h,r,g,b):EndProcedure
Here is the setting before creating the DLL:
Am I good so far?

I make my DLL from PB64 5.11. It is created.
But when using it, it crashes
[17:23:05] Waiting for the program to start...
[17:23:05] Executable type: Windows - x64 (64bit, Unicode)
[17:23:05] Executable started.
[17:23:05] [ERROR] Scrab_francais_translucent.pb (Line: 317)
[17:23:05] [ERROR] Invalid memory access. (reading error at address 8 )

The functions in the dll dont know about the screen that is why it crashes.

Clear,
the internal library does not match the new library. In addition, different memory areas and lists are used. A DLL has its own memory management.

Thank you (very much) for your comments.
How to use a DLL then?

Then you would have to execute all functions from the DLL.
But this is not allowed. That would be wrapping the PB functions and violates the licence condition of Purebasic
