Dialog with Splash Screen Example Code

Download Example Project - (142 kb)


Follow these steps to add a splash screen to your dialog based application:

  • Copy the Splash.cpp and Splash.h files from this example project to your project.
  • Add the following code to your applications InitInstance() method in the CWinApp derived class:
  • #include "Splash.h"
    
    BOOL CDialogsplApp::InitInstance()
    {
      // CG: The following block was added by the Splash Screen component.
      {
         CCommandLineInfo cmdInfo;
         ParseCommandLine(cmdInfo);
    
         CSplashWnd::EnableSplashScreen(cmdInfo.m_bShowSplash);
      }
      ...
      ...
    }
    
  • Next, use class wizard to add the OnCreate method to the CDialog derived class .cpp file, and add the following code to it:
  • #include "Splash.h"
    
    int CDialogsplDlg::OnCreate(LPCREATESTRUCT lpCreateStruct) 
    {
       if (CDialog::OnCreate(lpCreateStruct) == -1)
          return -1;
       
       // CG: The following line was added by the Splash Screen component.
       CSplashWnd::ShowSplashScreen(this);
    
       return 0;
    }

  • Added code to specify bmp file.

    I like the splasher code.  Works great.  I added the following code to use a file or resource item.  Code checks for filename in the home directory of the app, specified in string constant IDS_SPLASH_FILE, i.e. splash.bmp.  If it doesn't exist, then it will default to the resource, IDB_SPLASH.
    
    Splash.h:
    protected:
    	BOOL Create(CWnd* pParentWnd = NULL);
    	void HideSplashScreen();
    	static BOOL c_bShowSplashWnd;
    	static CSplashWnd* c_pSplashWnd;
    //New code
    	BOOL LoadBitmap();
    	CPalette  m_Palette;
    	int       m_nHeight;
    	int       m_nWidth;
    
    Splash.cpp:
    
    #include NameApp.h
    
    BOOL CSplashWnd::Create(CWnd* pParentWnd /*= NULL*/)
    {
    //	if (!m_bitmap.LoadBitmap(IDB_SPLASH))
    //		return FALSE;
    
            // Call LoadBitmap to load file or resource
    	VERIFY(LoadBitmap());
    ...
    }
    
    BOOL CSplashWnd::LoadBitmap()
    {     
    	CString mBmpName;
    
    	mBmpName.LoadString(IDS_SPLASH_FILE);
    	//Tell the splash screen which bitmap to use, 
    	CString mBitMap = ((CNameApp *)AfxGetApp())->GetHomeDirectory() + mBmpName;
    	CFileFind	mFind ;
    
      //Use LoadImage to get the image loaded into a DIBSection
      HBITMAP hBitmap;
      if (mFind.FindFile(mBitMap) )
        hBitmap = (HBITMAP) ::LoadImage(NULL, mBitMap, IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION | LR_DEFAULTSIZE | LR_LOADFROMFILE);
      else
        hBitmap = (HBITMAP) ::LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDB_SPLASH), IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION | LR_DEFAULTSIZE);
    
      //Check that we could load it up  
      if (hBitmap == NULL)       
        return FALSE;
    
      //Get the color depth of the DIBSection
      BITMAP bm;
      GetObject(hBitmap, sizeof(BITMAP), &bm);
      m_nHeight = bm.bmHeight;
      m_nWidth = bm.bmWidth;
    
      //Covert from the SDK bitmap handle to the MFC equivalent
      m_bitmap.Attach(hBitmap);
    
      //If the DIBSection is 256 color or less, it has a color table
      if ((bm.bmBitsPixel * bm.bmPlanes) <= 8 )     
      {
        //Create a memory DC and select the DIBSection into it
        CDC memDC;
        memDC.CreateCompatibleDC(NULL);
        CBitmap* pOldBitmap = memDC.SelectObject(&m_bitmap);
    
        //Get the DIBSection's color table
        RGBQUAD rgb[256];
        ::GetDIBColorTable(memDC.m_hDC, 0, 256, rgb);
    
        //Create a palette from the color table
        LPLOGPALETTE pLogPal = (LPLOGPALETTE) new BYTE[sizeof(LOGPALETTE) + (256*sizeof(PALETTEENTRY))];
        pLogPal->palVersion = 0x300;       
        pLogPal->palNumEntries = 256;
    
        for (WORD i=0; i<256; i++)       
        {
          pLogPal->palPalEntry[i].peRed = rgb[i].rgbRed;
          pLogPal->palPalEntry[i].peGreen = rgb[i].rgbGreen;
          pLogPal->palPalEntry[i].peBlue = rgb[i].rgbBlue;
          pLogPal->palPalEntry[i].peFlags = 0;
        }
        VERIFY(m_Palette.CreatePalette(pLogPal));
        
        //Clean up
        delete pLogPal;
        memDC.SelectObject(pOldBitmap);
      }
      else  //It has no color table, so use a halftone palette     
      {
        CDC* pRefDC = GetDC();
        m_Palette.CreateHalftonePalette(pRefDC);
        ReleaseDC(pRefDC);     
      }     
    
      return TRUE;

  • Display Splash Longer.

    I'm trying to make a simple text based program and have included a splash screen with photo. Currently the program works as intended, but the splash screen is extremely fast. How can I add a delay so that the splash screen is displayed for a longer time? I'm using MS Visual Basic 6.0.

      In the SetTimer line, SetTimer(1, 750, NULL); change the 750 to a higher number. Russ

  • How to add delay for displaying the main window

    Posted by Legacy on 03/25/1999 12:00am

    I tried to hide the main window, and show it when the HideSplashScreen function is called, but I always get a very short flash of the outline of the main window before it gets hidden.

    Otherwise, it looks like it's working fine.

    Any ideas?
