delphi中的inpubox，如何能控制它的位置？ 10

inputbox封装的是InputQuery函数，你可以查看InputQuery的源代码，发现在InputQuery函数里面动态创建了一个窗体，你可以把InputQuery函数的源代码复制出来，自己修改成可控制位置的就行了 

unit inputboxExs;

interface

uses Windows, Graphics, Forms, StdCtrls, Consts, Dialogs, Controls;

function InputQueryEx(const ACaption, APrompt: string;
  var Value: string; X, Y: Integer): Boolean;

function InputBoxEx(const ACaption, APrompt, ADefault: string; X, Y: Integer): string;  

implementation

function GetAveCharSize(Canvas: TCanvas): TPoint;
var
  I: Integer;
  Buffer: array[0..51] of Char;
begin
  for I := 0 to 25 do Buffer[I] := Chr(I + Ord('A'));
  for I := 0 to 25 do Buffer[I + 26] := Chr(I + Ord('a'));
  GetTextExtentPoint(Canvas.Handle, Buffer, 52, TSize(Result));
  Result.X := Result.X div 52;
end;

function InputQueryEx(const ACaption, APrompt: string;
  var Value: string; X, Y: 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 := ACaption;
      ClientWidth := MulDiv(180, DialogUnits.X, 4);
Left := X;
      Top := Y;
      Prompt := TLabel.Create(Form);
      with Prompt do
      begin
        Parent := Form;
        Caption := APrompt;
Left := MulDiv(8, DialogUnits.X, 4);
        Top := MulDiv(8, DialogUnits.Y, 8);
        Constraints.MaxWidth := MulDiv(164, DialogUnits.X, 4);
        WordWrap := True;
end;
      Edit := TEdit.Create(Form);
      with Edit do
      begin
        Parent := Form;
Left := Prompt.Left;
        Top := Prompt.Top + Prompt.Height + 5;
        Width := MulDiv(164, DialogUnits.X, 4);
        MaxLength := 255;
        Text := Value;
        SelectAll;
end;
      ButtonTop := Edit.Top + Edit.Height + 15;
      ButtonWidth := MulDiv(50, DialogUnits.X, 4);
      ButtonHeight := MulDiv(14, DialogUnits.Y, 8);
      with TButton.Create(Form) do
      begin
        Parent := Form;
        Caption := SMsgDlgOK;
        ModalResult := mrOk;
        Default := True;
        SetBounds(MulDiv(38, DialogUnits.X, 4), ButtonTop, ButtonWidth,
          ButtonHeight);
      end;
      with TButton.Create(Form) do
      begin
        Parent := Form;
        Caption := SMsgDlgCancel;
        ModalResult := mrCancel;
        Cancel := True;
        SetBounds(MulDiv(92, DialogUnits.X, 4), Edit.Top + Edit.Height + 15,
          ButtonWidth, ButtonHeight);
        Form.ClientHeight := Top + Height + 13;          
      end;
      if ShowModal = mrOk then
      begin
        Value := Edit.Text;
        Result := True;
      end;
    finally
      Form.Free;
    end;
end;

function InputBoxEx(const ACaption, APrompt, ADefault: string; X, Y: Integer): string;
begin
  Result := ADefault;
  InputQueryEx(ACaption, APrompt, Result, X, Y);
end;

以上是源代码，在Delphi源代码基础上稍微修改了下，我单独写在了一个文件中，使用时需要引用我这个单元文件，下面是调用示例：
uses inputboxExs;

procedure TForm1.Button2Click(Sender: TObject);
var str1, str2: string;
begin
  // 参数中的X，Y，就是你想设置的位置
  str1 := InputBoxEx('注意', '输入数字', str2, 100, 10);
  ShowMessage(str1);
end;
