DLL调试的方法(50分)

DLL工程中可以通过Run paramaters对话框指定某程序为宿主应用程序。然后你就可以在DLL代码中设置断点并且按F9运行它——就像在一个普通应用程序中做的那样。Delphi会运行指定的宿主程序，并且，通过编译带有调试信息的DLL，把你指引到DLL代码内的断点处。

可是我程序里面怎么设置断点都不会断下来。郁闷啊

library text;
uses
SysUtils,
Classes,
Windows,
Unit1 in 'Unit1.pas' {Form1},
varhead in 'varhead.pas';
{$R *.res}
exports
HookOn index 20,
Hookoff index 10;

function HookProc(nCode: Integer; WParam: WPARAM; LParam: LPARAM): LRESULT; stdcall;
begin

if nCode < 1 then
begin
if isLogin then
begin
isLogin := false;
gwnd := GetForegroundWindow;
OpenMap;

CloseHandle(hMapping);
if Login_num <> '' then
begin

BeginThread(nil, 0, @AutoLogin, nil, 0, PSum);
end;

end;

isBeep := false;
if (WPARAM = vk_home) and (((lParam shr 30) and $F) = 0) then
begin
if not Assigned(Form1) then

end;


我设置断点在
hootpro函数的
OpenMap;这行。可是不会到执行到这个地方断下来。。。好郁闷啊。。这个怎么回事啊

将dll的输出路径(Output directory)改为绝对路径试试

必须打开dll的dpr进行调试

绝对路径，肯定有设置啦

当然是在打开DLL的DPR，进行断点测试啦

单步跟踪看看

现在是没办法断点进去啊。而且这个DLL里面好多线程啊。。搞不懂怎么运行顺序
