From: Michael Rubinstein on 22 Nov 2006 13:35 Saulo, this code fragment expected CAPaint.dll to be present and loaded. As I stated, the code is a part of a library. It has an _Init() PROCEDURE I neglected to mention: PROCEDURE __MyPictureInit _INIT3 //whatever you call it IF File(WorkDir()+"CAPaint.dll") IF InitializeCAPaint() _RegisterExit( @ExitCAPaint()) _DebOut32(String2Psz("CAPAINT.DLL is loaded")) lCAPaint := TRUE ENDIF ENDIF The piece of code I showed was executed within a library if GLOBAL lCAPaint is TRUE. You don't need lCAPaint, but you have to make sure CAPaint.dll is initialized. If CAPaint.dll is initialized and you still get an empty poiner, go line by line starting with FindResource() line and look for empty pointers. This is old VO2.5 code I don't use for development anymore, but applications running it are still around. I don't use CAPaint.dll anymore, there is a better way. You can send me a private email so we don't created too much noise here and I don't have to disect my libraries.

From: Dirk (Belgium) on 23 Nov 2006 03:45 Hi, First CAPaint can only handle small jpeg files, thats why you have a null_ptr. There is a function called "CAPaintLastErrorMsg()" which can give you information about the error. There is also a function called "CAPaintShowErrors(True)" and you will have an errorbox on screen (for development purpose). For large jpg, use fabpaint. Yes, I use it. I load jpeg-file, show them on screen, lets make changes to this bitmap by the user, and save it back to HD as jpeg.

Thanks a lot to all you guys! Like always I got very great solutions here in this NG.
