thank you for your reply!
the reason I have it setup like this, is because I assign the pointers like
this:
Tempuser = new TUser();
Tempuser->pChat = &TUser::SendChat;
Tempuser->pData = &TUser::SendData;
Tempuser->pdisconnect = &TUser::Disconnect;
Tempuser->pkick = &TUser::Kick;
Tempuser->pPass = &TUser::ChangePass;
Tempuser->pPM = &TUser::SendPM;
I change the Delphi code like you suggested:
type
TSendMess = procedure (sb1:pchar;sb2:pchar) of object;safecall;
TCommon = procedure()of object;stdcall;
TCommon2 = procedure (sb1:pchar) of object;stdcall;
TCommon3 = function (sb1:pchar):boolean of object;stdcall;
The parameters are now fine, which makes me think that there is still hope
for me ;) Another problem has occurred though. When I call the pChat
function from the DLL, the 'this' pointer in the C++ function pChar is
pointing is equal to NULL, but when I check the object on the DLL side,
everything seems fine.
//Delphi Side
type PUser = ^TUser;
function Connect(User: PUser): integer;stdcall;
begin
User^.pChat('Test','123');
result = true;
end;
//C++ side
void __stdcall TUser::SendChat(const char* sFrom,const char* sMessage)
{
this->Socket->Send("<" + AnsiString(sFrom) + "> " + AnsiString(sMessage) +
"|");
}
Any thoughts?
thank you =)
