Open Word file with MFC implementation

When you open a Word file with MFC, you need to import the. olb file.
Select from a Type Library by View/classwizard->add class on the vc++6.0 toolbar ... Locate the required library file import.
The path used in this example is:
C:\Program Files\Microsoft Office\office11\msword. OLB.
(1), shown in Figure (2):

Figure (2) Press "ctlr+ left mouse button" to import the corresponding class, such as _application, Documents, _document

The detailed steps are as follows:
1. In vc++6.0, create a new dialog-based MFC AppWizard (EXE) named: Openword, (3), figure (4), as shown:

Figure (3) Creating an MFC project: Openword

Figure (4) Select the "type of application" as: Dialog based
2. For resource files, add three controls to the dialog box: a static text control, an edit box control, and a button control. (5) Shown:

Click "View"/"ClassWizard" on the toolbar to import the corresponding Msword.olb file, as shown in figure (1) above, figure (2).
4. Double-click the "Open" button in the dialog box to add a response function as shown in Onbutopen (), (6):

The code is as follows:

voidCopenworddlg:: Onbutopen() {//Todo:add your control notification handler code hereCFileDialog Dlg (TRUE,NULL,NULL, ofn_hidereadonly|Ofn_overwriteprompt,"All Files (*.doc) |*.doc| |", AfxGetMainWnd ());//Construct File Open dialog boxCString strpath;//DECLARE variables    if(DLG.DoModal ()==IDOK)//Determine if the "open" button is pressed{strpath=Dlg.GetPathName ();//Get file pathM_path.SetWindowText (strpath);//Show file path        //word Applications_application app;        Documents docs; _document Doc;//Initialize connectionApp.CreateDispatch ("Word. Application "); CComVariant A (_t (strpath)), B (false), C (0), D (true); Docs.AttachDispatch (App.GetDocuments ()); Doc.AttachDispatch (docs.ADD (&A&B&C&d));//DisplayApp.SetVisible (true);//Release EnvironmentDoc.ReleaseDispatch (); Docs.ReleaseDispatch (); App.ReleaseDispatch (); }}

4. Associate a control-type variable for the edit box: M_path, (8):

5. Import Msword.h and atlbase.h in the OpenWorldDlg.h header file

#include "msword.h"#include <atlbase.h>

(9) Shown:

Add two references in XXXDlg.h
6. Initialize the COM library. Add the following statement to the application class InitInstance:

::CoInitialize(NULL);

(10) Shown:

Figure (10) in XXX.cpp's InitInstance () function, add the initialization statement for the COM library
The XXX.cpp here refers to the project name. cpp File: OpenWord.cpp
7. The effect is as follows:
