Hi Yury, have now recompiled the DLL with the latest SVN build using the 2_2 fixes but get the same problem, load library returns the same hex value 0x7c37000 - the actual procedure I have in the DLL is as follows // cut code here function GetModuleHandle(lpModuleName: PCHAR): cardinal; stdcall; external 'kernel32.dll' name 'GetModuleHandleA'; function LoadLibrary(lpLibFileName: PCHAR): cardinal; stdcall; external 'kernel32.dll' name 'LoadLibraryA'; function GetProcAddress(hModule: HMODULE; lpProcName: LPCSTR): FARPROC; stdcall; external 'kernel32.dll' name 'GetProcAddress'; procedure debug(fn, tx : string); var f : textfile; begin assignfile(f,'c:\skelgina.log'); if fileexists('c:\skelgina.log') then append(f) else rewrite(f); writeln (f,timetostr(now) + ' - ' + fn + ': ' + tx); writeln (f); closefile(f); end; procedure GetProcedureAddress(var P: Pointer; const ModuleName, ProcName: string); stdcall; var ModuleHandle: cardinal; begin debug('GetProcedureAddress','Called'); debug('GetProcedureAddress','ModuleName: '+modulename); debug('GetProcedureAddress','ProcName: '+procname); if not Assigned(P) then begin debug('GetProcedureAddress','P is not assigned'); begin ModuleHandle := SafeLoadLibrary('MSGINA.DLL'); debug('GetProcedureAddress','LoadLibrary MSGINA.DLL returns $'+inttohex(ModuleHandle,16)); end; P := Pointer(GetProcAddress(ModuleHandle, PChar(ProcName))); end else debug('GetProcedureAddress','P is already assigned'); debug('GetProcedureAddress','Exits - P assigned '+booltostr(assigned(p))); end; // end code here Any thoughts on this ? I pulled the GetProcedureAddress function from the Jwa??? components to test incase it was my implementation of the LoadLIbrary code in FPC but obviously it's not !!!
