1. I want to a DLL can invoke a function of the main program, so I made an excuse for

 
The unit uMainAppInterface; 

Interface 
USES Classes, DB, DBClient; 
Type 
IMainAppInterface=interface 
[' {3 fbfa782-9626-4372-8391 - DA8F4C21397E} '] 

The function ExcuteSQL (SQLStr: String; CDS: the TClientDataSet) : integer; 
The function CurrentDBType: Integer; 
end; 
Implementation 


End. 

2. The main program output

 function ManApp: IMainAppInterface; 
The begin 
Result:=TMainAppInterface. Create; 

end; 
Exports 
ManApp; 

3. The DLL for

 
TMainAppInterface=function: IMainAppInterface; 
Var 
MainAppHandle: THandle; 

The begin 

MainAppHandle:=loadlibrary (' Pproperty. Exe); 
@ MainAppInterface:=GetProcAddress call (MainAppHandle, 'ManApp'); 
end; 

4. The interface is implemented, has now become a normal call, but now in the IDE compiler running, sometimes an error external exception EEFFACE
The Event LOG is
The Module Load: profapi. DLL. No Debug Info. The Base Address: $75 ba0000. Process Pproperty. Exe (9564)
Then direct IDE died,

Don't open the IDE without error, it is very strange ~ ~ ~ ~ ~ ~

DELPHI version 2010 system is Windows 7

Turn to 1. If this method is the formal approach,
2. What is at the wrong reason ~ ~ ~
