启动程序并使用现有程序Delphi 2010进行停靠

您可能希望修改窗口样式,位置等.在尝试在新进程中查找窗口句柄之前,还要调用WaitForInputIdle.您必须为新流程提供入门机会.

你现在拥有的是一个非常奇怪的野兽.在一个容器内,您有两个进程.每个进程都有自己的UI线程.您可以一次显示两个模态对话框并与之交互.你可以拥有的乐趣真是无止境！

只是为了一点乐趣,我开始编写一个简单的Delphi应用程序来完成这项工作.它相当脆弱,似乎只适用于非常基本的应用程序.我想你可能会花很长时间努力使这项工作做得很好,但结果仍然不尽如人意.如果我是你,我会寻找其他解决方案,特别是当你拥有这个C#应用程序的源代码时.当然,您可以将其功能公开为ActiveX？

无论如何,为了您的娱乐,我提供以下非常不完美的代码：

program AppHost;

uses
  Windows,Messages,SysUtils,Forms,Controls,ComCtrls;

{$R *.res}

procedure ResizePage(Page: TTabSheet);
var
  hwnd: Windows.HWND;
  Rect: TRect;
begin
  hwnd := Page.Tag;
  Rect := Page.ClientRect;
  MoveWindow(hwnd,Rect.Left,Rect.Top,Rect.Right-Rect.Left,Rect.Bottom-Rect.Top,True);
end;

type
  PEnumData = ^TEnumData;
  TEnumData = record
    ProcessID: DWORD;
    hwnd: HWND;
  end;

function EnumWindowsProc(hwnd: HWND; lParam: LPARAM): BOOL; stdcall;
var
  ProcessId: DWORD;
  EnumData: PEnumData;
begin
  EnumData := PEnumData(lParam);
  GetWindowThreadProcessId(hwnd,ProcessId);
  if EnumData.ProcessID=ProcessID then begin
    EnumData.hwnd := hwnd;
    Result := False;
    exit;
  end;
  Result := True;
end;

procedure Absorb(PageControl: TPageControl; const App: string; StartupInfo: TStartupInfo);
var
  Page: TTabSheet;
  ProcessInformation: TProcessInformation;
  EnumData: TEnumData;
begin
  Page := TTabSheet.Create(PageControl);
  Page.PageControl := PageControl;
  Page.Caption := ChangeFileExt(ExtractFileName(App),'');
  CreateProcess(PChar(App),nil,False,StartupInfo,ProcessInformation);
  WaitForInputIdle(ProcessInformation.hProcess,INFINITE);
  EnumData.ProcessID := ProcessInformation.dwProcessId;
  EnumData.hwnd := 0;
  EnumWindows(@EnumWindowsProc,LPARAM(@EnumData));
  Page.Tag := Integer(EnumData.hwnd);
  SetParent(HWND(Page.Tag),Page.Handle);
  ResizePage(Page);
end;

type
  TEventProvider = class
  private
    FForm: TForm;
    FPageControl: TPageControl;
    procedure FormResize(Sender: TObject);
  public
    constructor Create(Form: TForm; PageControl: TPageControl);
  end;

{ TEventProvider }

constructor TEventProvider.Create(Form: TForm; PageControl: TPageControl);
begin
  inherited Create;
  FForm := Form;
  FPageControl := PageControl;
  FForm.OnResize := FormResize;
end;

procedure TEventProvider.FormResize(Sender: TObject);
var
  i: Integer;
begin
  for i := 0 to FPageControl.PageCount-1 do begin
    ResizePage(FPageControl.Pages[i]);
  end;
end;

procedure Main(Form: TForm);
var
  StartupInfo: TStartupInfo;
  PageControl: TPageControl;
begin
  Form.ClientHeight := 600;
  Form.ClientWidth := 800;
  Form.Caption := 'All your processes are belong to us';
  PageControl := TPageControl.Create(Form);
  PageControl.Parent := Form;
  PageControl.Align := alClient;
  StartupInfo.cb := SizeOf(StartupInfo);
  GetStartupInfo(StartupInfo);
  Absorb(PageControl,'C:WindowsNotepad.exe',StartupInfo);
  Absorb(PageControl,'C:Program FilesCommandLinedepends.exe',StartupInfo);
  TEventProvider.Create(Form,PageControl);
end;

var
  Form: TForm;

begin
  Application.Initialize;
  Application.MainFormOnTaskbar := True;
  Application.CreateForm(TForm,Form);
  Main(Form);
  Application.Run;
  Form.Free;
end.
