DLL Prototype

jimvaughan · April 22

After migration I see this in the logfile.
Imported "DLL_GDI32_MIGRATED" DLL Prototype record OK
However, when my code calls a function like CreateCopatibleBitmap, OI says the code could not be found (or words to that effect).
Do I need to do some additional steps after migrating the DLL prototype records?

Bit out of my league here, but, do I remember something about being 'registered/compiled'
Hey - Are the .dlls in the OI10 folder.

Hmm, this one is actually part of the WinAPI.

I spelt the fn call above wrong i's correct in my code, but doesn't work.

Sorry, but you need someone more expert from here on to chip in!!

is $CreateCompatibleBitmap* in SYSOBJ

if not you may need to do Declare_FCNS

No it is not.
Does anyone know if the migration process copies all dll prototype records and does the Declare_Fcns? Or do have to manualy do this? I do it mnually if need be, I just want to ensure I am not missing anything.

I found this in the forum where Carl's responses may help you:

Thanks that is helpful.

I figured it all out, yes you need to compile any migrated dll prototype records. However OI 10 has a bunch already setup, including one for GDI and it includes CreateCompatibleBitmap. However it is aliased so I need to modify my code to use msWin_CreateCompatibleBitmap.

Thanks for the help Barry.
