MDI-Login. Basic skeleton project

Multiple-Document Interface (MDI)

Applications with Login Modal Dialog

The modal window is a child of one of the main windows. However, it is blocking all the top-level windows once it is open.

Submitted app solves this problem. Describes how to use standard dialogs in an MDI application.

Design Components Library ( NDC )

Components for MFC WinForm help developers execute Design with modular and customizable UI components. These components enable a reliable development workflow to build beautiful and functional user experiences for C++ MFC Desktop application.

Custom MDI Frame color

CMainFrame :

        protected:
             CClientWnd  m_Client;

OnCreateClient action :

        BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
        {
            if (CMDIFrameWnd::OnCreateClient(lpcs, pContext))
            {
	            m_Client.SubclassWindow(m_hWndMDIClient);
	            return TRUE;
            }

            return CMDIFrameWnd::OnCreateClient(lpcs, pContext);
        }

OnClose action:

        void CMainFrame::OnClose(){
            .....
            m_Client.UnsubclassWindow();
            CMDIFrameWnd::OnClose();
        }

Custom Dialogs

Dialogs inform users about a task and can contain critical information, require decisions, or involve multiple tasks.

Using: change reference from CDialog to CDesignDialog CModalDialog to CModalDesignDialog

     include: CDesignDialog.h

Create Resource DLLs and Language Support

Easy instructions for creating custom language support to your application.

Create Satellite DLL ( resource-only DLL )

1. Create Empty Dynamic Link Library project with Windows Desktop Wizard.

2. Create a new resource ( .rc file ).

3. copy all application resource and file resource.h into Satellite DLL.

4. Modify your application resource as your needs.

5. Specify the /NOENTRY linker option. ( Project Properties -> Linker -> Advanced -> No Entry Point -> Select Yes option )

6. Create Satellite DLL for all your application configuration

Use a Satellite DLL

Load satellite DLL into your application initialization:

for example:

        //////////////////////////////////////////////
        // CMDIAppViewApp initialization

        BOOL CMDIAppViewApp::InitInstance()
        {

            hResourceDLL = LoadLibrary(L"ResourceDLL.Dll");
            AfxSetResourceHandle(hResourceDLL);

            AfxEnableControlContainer();
            ....

You can select resources DLL file depending on your application configuration

3. Unload your sattelite DLL

for example:

        int CMDIAppViewApp::ExitInstance()
        {
            // Restores the EXE as the resource container.
            //
            AfxSetResourceHandle(AfxGetApp()->m_hInstance); 
            FreeLibrary(hResourceDLL);
            hResourceDLL = NULL;

            return CWinApp::ExitInstance();
        }

Adding Icons to Menu Items

This is an easy way to add icons to the menu.

1. Create bitmap image.

If you using GIMP please export with:

		 Compatable Options:
		   - Do not write color space information
		 Advanced Options:  
		  - 24 bits R8 G8 B8

2. Add to .rc file:

   	ID_APP_ABOUT   BITMAP   DISCARDABLE    "res\\bitmap1.bmp"
   

where ID_APP_ABOUT - your menu item ID

3. Add WM_INITMENUPOPUP handler in MainFrame class:

for example:

ON_WM_INITMENUPOPUP():

		void CMainFrame::OnInitMenuPopup(CMenu* pMenu, UINT nIndex, BOOL bSysMenu)
		{
			CMDIFrameWnd::OnInitMenuPopup(pMenu, nIndex, bSysMenu);

			if (bSysMenu)
			{
				pMenu = GetSystemMenu(FALSE);
			}
			MENUINFO mnfo;
			mnfo.cbSize = sizeof(mnfo);
			mnfo.fMask = MIM_STYLE;
			mnfo.dwStyle = MNS_CHECKORBMP | MNS_AUTODISMISS;
			::SetMenuInfo(pMenu->GetSafeHmenu(), &mnfo);

			MENUITEMINFO minfo;
			minfo.cbSize = sizeof(minfo);

			for (UINT pos = 0; pos < pMenu->GetMenuItemCount(); pos++)
			{
				minfo.fMask = MIIM_FTYPE | MIIM_ID ;
				pMenu->GetMenuItemInfo(pos, &minfo, TRUE);

				if (ID_APP_ABOUT == minfo.wID) {

					if (hBitmapAbout == NULL) {
						hBitmapAbout = (HBITMAP)::LoadBitmap(::AfxGetResourceHandle(),
							MAKEINTRESOURCE(ID_APP_ABOUT));
					}
					SetMenuItemBitmaps(pMenu->m_hMenu, pos, 
						  MF_BYPOSITION , hBitmapAbout, hBitmapAbout);
				}
			}
		}

Destructor:

		CMainFrame::~CMainFrame()
		{
			if (hBitmapAbout != NULL) {
				DeleteObject(hBitmapAbout);
			}
		}

Constructor:

		CMainFrame::CMainFrame()
		{
			// TODO: add member initialization code here
			NotLoginExit = false;
			hBitmapAbout = NULL;
		}
