Lo primero que podrías probar es: WinExec(PChar('c:\path_hasta_winword\winword.exe'),SW_SHOWNORMAL); {Ejecuta el WinWord.Exe} Con WinExec, el programa Delphi no espera a que termine la ejecución de la aplicacion externa. Si queremos que nuestra aplicacion Delphi espere hasta que la aplicación llamada haya terminado, podemos utilizar esta otra forma: function TForm1.WinExecAndWait32(FileName:String; Visibility:integer):integer; var zAppName:array[0..512] of char; zCurDir:array[0..255] of char; WorkDir:String; StartupInfo:TStartupInfo; ProcessInfo:TProcessInformation; Resultado: DWord; begin StrPCopy(zAppName,FileName); GetDir(0,WorkDir); StrPCopy(zCurDir,WorkDir); FillChar(StartupInfo,Sizeof(StartupInfo),#0); StartupInfo.cb := Sizeof(StartupInfo); StartupInfo.dwFlags := STARTF_USESHOWWINDOW; StartupInfo.wShowWindow := Visibility; if not CreateProcess(nil, zAppName, { pointer to command line string } nil, { pointer to process security attributes}nil, { pointer to thread security attributes} false, { handle inheritance flag }CREATE_NEW_CONSOLE { creation flags } NORMAL_PRIORITY_CLASS, nil, { pointer to new environment block } nil, { pointer to current directory name }StartupInfo, { pointer to STARTUPINFO } ProcessInfo) then Result := -1 { pointer to PROCESS_INF } else begin WaitforSingleObject(ProcessInfo.hProcess,INFINITE); GetExitCodeProcess(ProcessInfo.hProcess,Resultado); Result := Resultado; end; end; Otra versión de la anterior, que ejecuta Applicacion.ProcessMessages para que no se muera tu form mientras espera: function WinExecAndWait32(FileName:String; Visibility:integer):integer; var zAppName:array[0..512] of char; zCurDir:array[0..255] of char; WorkDir:String; StartupInfo:TStartupInfo; ProcessInfo:TProcessInformation; Resultado,exitCode: DWord; begin StrPCopy(zAppName,FileName); GetDir(0,WorkDir); StrPCopy(zCurDir,WorkDir); FillChar(StartupInfo,Sizeof(StartupInfo),#0); StartupInfo.cb := Sizeof(StartupInfo); StartupInfo.dwFlags := STARTF_USESHOWWINDOW; StartupInfo.wShowWindow := Visibility; CreateProcess(nil, zAppName, { pointer to command line string }nil, { pointer to process security attributes} nil, { pointer to thread security attributes} false, { handle inheritance flag } CREATE_NEW_CONSOLE or { creation flags } NORMAL_PRIORITY_CLASS, nil, { pointer to new environment block } nil, { pointer to current directory name } StartupInfo, { pointer to STARTUPINFO } ProcessInfo); {Espera a que termine la ejecucion} {Wait until execution finish} repeat exitCode := WaitForSingleObject( ProcessInfo.hProcess,1000); Application.ProcessMessages; until (exitCode <> WAIT_TIMEOUT); GetExitCodeProcess(ProcessInfo.hProcess,Resultado); MessageBeep(0); CloseHandle(ProcessInfo.hProcess ); Result:=Resultado; end; Sacado de Trucomanía (www.q3.nu).
