Change text of other App Edit Control

[Razor]

Hi!

I want to change/insert text to a Tedit control of other application ( Find File Dialog ).
I got this so far but i guess Setwindowtext won't work

Delphi-Quellcode:

procedure TForm1.FormCreate(Sender: TObject);
var
  wndMain, wndChild: HWND;
begin
  wndMain := FindWindow('CabinetWClass','Search Results');
  if wndMain <> 0 then
  begin
    wndChild := FindWindowEx(wndMain, 0, 'WorkerW', nil);
    wndChild := FindWindowEx(wndChild, 0, 'ReBarWindow32', nil);
    wndChild := FindWindowEx(wndChild, 0, 'UniversalSearchBand', nil);
    wndChild := FindWindowEx(wndChild, 0, 'Search Box', nil);
 wndChild := FindWindowEx(wndChild, 0, 'SearchEditBoxWrapperClass', nil);
  //  WINDOWS.SetWindowTextA(wndchild,'s');
     //WINDOWS.SetWindowTextW(wndchild,'s');
     sendmessage(wndchild,WM_settext,0,0);
    if wndChild <> 0 then
    begin
      ShowMessage('Window Handle: ' + IntToStr(wndChild));

    end;
  end;
end;

Hi,

To set the text of a control in another process, send the WM_SETTEXT message directly instead of calling SetWindowText.
SetWindowText

Well clearly its not working toms...I want to specify what i want to search from delphi app to the find file dialog directory is not enough.Thats why this way..

Delphi-Quellcode:

uses ddeman;

procedure TForm1.Button1MouseDown(Sender: TObject; Button: TMouseButton;
  Shift: TShiftState; X, Y: Integer);

  var
  wndMain, wndChild: HWND;
    msg : String;

begin
  wndMain := FindWindow('CabinetWClass','Search Results');
  if wndMain <> 0 then
  begin
    wndChild := FindWindowEx(wndMain, 0, 'WorkerW', nil);
    wndChild := FindWindowEx(wndChild, 0, 'ReBarWindow32', nil);
    wndChild := FindWindowEx(wndChild, 0, 'UniversalSearchBand', nil);
    wndChild := FindWindowEx(wndChild, 0, 'Search Box', nil);
    wndChild := FindWindowEx(wndChild, 0, 'SearchEditBoxWrapperClass', nil);

msg := 'search for this';



    if wndChild <> 0 then
    begin
      ShowMessage('Window Handle: ' + IntToStr(wndChild));
       SendMessage(wndchild, WM_SETTEXT, 0, LongInt(PChar(msg)));

  end;

  end;
end;



procedure TForm1.FormCreate(Sender: TObject);
begin
  with TDDEClientConv.Create(Self) do begin
   ConnectMode := ddeManual;
   ServiceApplication := 'explorer.exe';
   SetLink( 'Folders', 'AppProperties') ;
   OpenLink;
   ExecuteMacro
       ('[FindFolder(, C:\DelphiTips)]', False) ;
   CloseLink;
   Free;
  end;


end;

What's your OS? Is the message ShowMessage(..) shown?

The snippet dosent seem to work with DElphi 2010..

[DCC Error] Unit1.pas(90): E2010 Incompatible types: 'Char' and 'AnsiChar'
 ExecuteMacro(PChar('[FindFolder(, '+ sVerz +')]'), False); [DCC Warning] Unit1.pas(89): W1002 Symbol 'IncludeTrailingBackslash' is specific to a platform
sVerz := IncludeTrailingBackslash(Verzeichnis);
