这个资料你瞧瞧吧

如果看不明白app2001的。
去看看李維的《inside VCL》第一章，裡面提到了有講的。

老兄：
是在object pascal里面写窗体。。。。。。
不是在delphi里面写窗体。。。。

可以参照一下函数的代码
function GetString(Var sResult:string
sDef:string
iMaxLen:Integer):Boolean;
var
Form: TForm;
Prompt: TLabel;
Edit: TEdit;
DialogUnits: TPoint;
ButtonTop, ButtonWidth, ButtonHeight: Integer;
begin
Result := False;
Form := TForm.Create(Application);
with Form do
try
Canvas.Font := Font;
DialogUnits := GetAveCharSize(Canvas);
BorderStyle := bsDialog;
Caption := '提示';
ClientWidth := MulDiv(180, DialogUnits.X, 4);
ClientHeight := MulDiv(63, DialogUnits.Y, 8);
Position := poScreenCenter;
Prompt := TLabel.Create(Form);
with Prompt do
begin
Parent := Form;
AutoSize := True;
Left := MulDiv(8, DialogUnits.X, 4);
Top := MulDiv(8, DialogUnits.Y, 8);
Caption := '请输入：';
end;
Edit := TEdit.Create(Form);
with Edit do
begin
Parent := Form;
Left := Prompt.Left;
Top := MulDiv(19, DialogUnits.Y, 8);
Width := MulDiv(164, DialogUnits.X, 4);
MaxLength := 255;
Text := sDef;
SelectAll;
end;
ButtonTop := MulDiv(41, DialogUnits.Y, 8);
ButtonWidth := MulDiv(50, DialogUnits.X, 4);
ButtonHeight := MulDiv(14, DialogUnits.Y, 8);
with TButton.Create(Form) do
begin
Parent := Form;
Caption := '确定';
ModalResult := mrOk;
Default := True;
SetBounds(MulDiv(38, DialogUnits.X, 4), ButtonTop, ButtonWidth,
ButtonHeight);
end;
with TButton.Create(Form) do
begin
Parent := Form;
Caption := '取消';
ModalResult := mrCancel;
Cancel := True;
SetBounds(MulDiv(92, DialogUnits.X, 4), ButtonTop, ButtonWidth,
ButtonHeight);
end;
if ShowModal = mrOk then
begin
sResult := Edit.Text;
Result := True;
end;
finally
Form.Free;
end;
end;

哦，那就当我没说了

打开Delphi的单元文件看下怎么创建的。
不知道你的用途是？

yaoc:
在object pascal 中怎么还有Tform,Tlabel之类的东西哟？？？
是在object pascal而不是在delphi中。。。。。。
谢谢！！！

明白，无法为你效劳！

不用VCL，而使用SDK写出的窗体

program WindowDemo;

uses Windows, Messages;

// 窗口函数，窗口接到消息时被Windows所调用
function WindowProc(hwnd : HWND
uMsg : Cardinal
wParam : WPARAM;
lParam : LPARAM) : LResult
stdcall;
begin
Result := 0;

case uMsg of
// 关闭窗口消息，当用户关闭窗口后，通知主消息循环结束程序
WM_CLOSE : PostMessage(hwnd, WM_QUIT, 0, 0)

// 鼠标左键按下消息
WM_LBUTTONDOWN : MessageBox(hwnd, 'Hello!', '和您打个招呼',
MB_ICONINFORMATION)


else
// 其它消息做默认处理
Result := DefWindowProc(hWnd, uMsg, wParam, lParam)

end;
end;

var
wndcls : WNDCLASS
// 窗口类的记录（结构）类型
hWnd : THandle;
Msg : tagMSG
// 消息类型
begin
wndcls.style := CS_DBLCLKS
// 允许窗口接受鼠标双击
wndcls.lpfnWndProc := @WindowProc
// 为窗口类指定窗口函数
wndcls.cbClsExtra := 0;
wndcls.cbWndExtra := 0;
wndcls.hInstance := hInstance;
wndcls.hIcon := 0;
wndcls.hCursor := LoadCursor(hInstance, 'IDC_ARROW');
wndcls.hbrBackground := COLOR_WINDOWFRAME;
wndcls.lpszMenuName := nil;
wndcls.lpszClassName := 'WindowClassDemo'
// 窗口类名称

// 注册窗口类
if RegisterClass(wndcls) = 0 then
Exit;

// 创建窗口
hWnd := CreateWindow(
'WindowClassDemo', // 窗口类名称
'WindowDemo', // 窗口名称
WS_BORDER or WS_CAPTION or WS_SYSMENU, // 窗口类型
Integer(CW_USEDEFAULT),
Integer(CW_USEDEFAULT),
Integer(CW_USEDEFAULT),
Integer(CW_USEDEFAULT),
0,
0,
hInstance,
nil
);
if hWnd = 0 then
Exit;

// 显示窗口
ShowWindow(hWnd, SW_SHOWNORMAL);
UpdateWindow(hWnd);

// 创建主消息循环，处理消息队列中的消息并分发
// 直至收到WM_QUIT消息，退出主消息循环，并结束程序
// WM_QUIT消息由PostMessage()函数发送
while GetMessage(Msg, hWnd, 0, 0) do
begin
TranslateMessage(Msg);
DispatchMessage(Msg);
end;
end.

wr960204的代码还有点意思，试试看！！！！！

同意wr960204的

接受答案了.
