客户端的部分代码
var
FUserName : WideString; //用户名称 '用户名'
FMode : WideString; //机器类型 '后台'
FHost : WideString; //计算机名 'HP2000'
FIP : WideString; //计算机IP '202.202.202.202'
FConntime : WideString; //登陆时间 '0000年00月00日 00:00:00 000'

// 功能:将 String 转换成 WideString
function ChAnsiToWide(const StrA: AnsiString): WideString;
var
nLen: integer;
begin
Result := StrA;
if Result <> '' then
begin
nLen := MultiByteToWideChar(936, 1, PChar(@StrA[1]), -1, nil, 0);
SetLength(Result, nLen - 1);
if nLen > 1 then
MultiByteToWideChar(936, 1, PChar(@StrA[1]), -1, PWideChar(@Result[1]), nLen - 1);
end;
end;

主要相关代码就这个,为什么客户端关闭的时候进程还在
[粤]GuoQingaa(65517285) 13:19:26
怎么改
[粤]GuoQingaa(65517285) 13:20:05
//退出系统
procedure TFrmCltMain.FormCloseQuery(Sender: TObject;
var CanClose: Boolean);
begin
// if Application.MessageBox(PChar('确定要退出'+ Application.Title +'吗?'), '询问', MB_YESNO + MB_ICONQUESTION)=IDYES then
// begin
DM.SocketCn.AppServer.DelUser(FUserName, FMode, GetComputerName,
GetComputerIP, FConntime);
CanClose := True;
// end
// else
// CanClose := False;
end;
