You the function name is: mygo or my_go?
@ MyRro:=GetProcAddress call (MyHandle, PChar (' mygo '));

CodePudding user response:

Thank you upstairs, the problem is not the function name (procedure mygo (); Cdecl; External 'my. DLL';
), I wrote a,
@ MyRro:=GetProcAddress call (MyHandle, PChar (' mygo '));
I'm afraid I write in a way that is adjustable dynamic link library is wrong, this DLL has a total of three documents, estimate mydll also calls the other files,

Delphi debugger pop-up window is memory?????? This kind of question marks,
I suspect the DLL has a problem, but I don't know how to confirm, thank you for advice

@ MyRro:=GetProcAddress call (MyHandle, PChar (' mygo '));
Modified to MyRro:=GetProcAddress call (MyHandle, PChar (' mygo '));
