Implementing Automation - Implementing the Automated Edit Menu

Start with the project you created in Implementing Vector Automation

Take the following steps to implement an Edit menu in the application:

1. Select the File->New menu option. In the dialog box, select Resource Script and press Enter.

2. Right-click the script you just created. Select Insert and then Menu from the dialog box that appears and click OK.

3. Create the following Menu structure:

   IDR_MENU1 
    &File 
    &Undo         with ID = IDM_EDIT_UNDO 
    &Redo         with ID = IDM_EDIT_REDO 
    Cu&t          with ID = IDM_EDIT_CUT 
    &Copy         with ID = IDM_EDIT_COPY 
    &Paste        with ID = IDM_EDIT_PASTE 
    &Delete       with ID = IDM_EDIT_DELETE 
    Select &All   with ID = IDM_EDIT_SELECTALL 
    &Unselect All with ID = IDM_EDIT_UNSELECTALL 
    P&rint        with ID = IDM_EDIT_PRINT 
    &Reset        with ID = IDM_EDIT_RESET 

4. Select File->Save from the menu. Enter vecaut.rc in the Save As box and click Save.

5. Select Insert->Files into Project, browse to the vecaut.rc file just created and click Add.

6. Add the following line right under #include "C:\LEADTOOLS21\Include\ltaut.h".

   #include "resource.h" 

7. Change the line

   WndClass.lpszMenuName = NULL; 

   In the WinMain function to

   WndClass.lpszMenuName = MAKEINTRESOURCE( IDR_MENU1 ); 

8. Add the following lines of code right after the return 0L; statement of case WM_CREATE:

   case WM_COMMAND: 
   switch (LOWORD(wParam)) 
   { 
      case IDM_EDIT_UNDO: 
      L_AutUndo(pAutomation, 0L); 
      InvalidateRect(hWnd, NULL, FALSE); 
      return 0L; 
      case IDM_EDIT_REDO: 
      L_AutUndo(pAutomation, 0L); 
      InvalidateRect(hWnd, NULL, FALSE); 
      return 0L; 
      case IDM_EDIT_CUT: 
      L_AutCut(pAutomation, 0L); 
      InvalidateRect(hWnd, NULL, FALSE); 
      return 0L; 
      case IDM_EDIT_COPY: 
      L_AutCopy(pAutomation, 0L); 
      InvalidateRect(hWnd, NULL, FALSE); 
      return 0L; 
      case IDM_EDIT_PASTE: 
      L_AutPaste(pAutomation, 0L); 
      InvalidateRect(hWnd, NULL, FALSE); 
      return 0L; 
      case IDM_EDIT_DELETE: 
      L_AutDelete(pAutomation, 0L); 
      InvalidateRect(hWnd, NULL, FALSE); 
      return 0L; 
      case IDM_EDIT_SELECTALL: 
      L_AutSelect(pAutomation, AUTOMATION_SELECT_ALL, 0L); 
      InvalidateRect(hWnd, NULL, FALSE); 
      return 0L; 
      case IDM_EDIT_UNSELECTALL: 
      L_AutSelect(pAutomation, AUTOMATION_SELECT_NONE, 0L); 
      InvalidateRect(hWnd, NULL, FALSE); 
      return 0L; 
      case IDM_EDIT_PRINT: 
      L_AutPrint(pAutomation, 0L); 
      return 0L; 
      case IDM_EDIT_RESET: 
      ResetView(hWnd, &Vector, pAutomation); 
      return 0L; 
   default: 
      break; 
   } 
   break; 

9. Compile and run the demo. You should be able to perform common operations found in most Windows programs on your vector image.
