Developer's Corner / Flicker with transparent labels on different panels

« on: May 08, 2008, 11:52 AM »

I have a Form with a Panel mainBackPanel. To mainBackPanel I add different panels say redPanel, greenPanel, bluePanel depending on key pressed, r, g, b respectively. Each panel has a different image (say tomatoes, trees, sky) and a transparent label.

Now when the panel changes, I see a small flicker on the area covered by the label.

mainBackPanel (to which the individual panels are added) is double buffered.

All KeyEvents are being handled by MainForm in the following method

void mainFormKeyUpHandler(Object o, KeyEventArgs kev)
{   
   if( kev.KeyCode == Keys.R )
   {
         this.mainBackPanel.Controls.Clear();
         this.mainBackPanel.SuspendLayout();
         this.mainBackPanel.Controls.Add(this.mainFormPanel);                               this.mainBackPanel.ResumeLayout();   
   }   
   else
   .
   .
   .
}


The code, in .NET 2.0, can be found here.

You will need to put 3 image files namely fb.jpg, mf.jpg and pl.jpg in bin/debug folder prior to running the app.

Please suggest how to get rid of the flicker.

Thanks

My Final solution

public SplashScreen()
      {
         
         this.TopMost = true;
         this.ShowInTaskbar = false;
         this.FormBorderStyle = FormBorderStyle.None;
         this.StartPosition = FormStartPosition.CenterScreen;
         
         Image img = Bitmap.FromFile(LetsYoConfig.SplashFileName);
         this.Size = img.Size;

         LockWindowUpdate(this.Handle);
         
         try
         {
            this.BackColor = this.TransparencyKey = Color.White;
            
            Bitmap b = new Bitmap(img);
            this.BackgroundImage = splashImage = (Image) b;
         }
         finally
         {
            LockWindowUpdate(IntPtr.Zero);
         }
      }

Everything works as expected.
Thank you.

My Workaround

+ Set the Splash Screen's StartPosition to Manual
+ Set Splash Screen's Location to Center of the Screen
+ Call LockWindowUpdate
+ Rest of the code

Code is

public SplashScreen()
{
   try
   {
      Image img = Bitmap.FromFile(LetsYoConfig.SplashFileName);
      SetSplashScreenPosition(img.Size.Width, img.Size.Height);

      LockWindowUpdate(this.Handle);
      
      this.TopMost = true;
      this.ShowInTaskbar = false;
      this.FormBorderStyle = FormBorderStyle.None;
      this.StartPosition = FormStartPosition.CenterScreen;
      
      this.BackColor = this.TransparencyKey = Color.White;
      
      Bitmap b = new Bitmap(img);
      b.MakeTransparent(b.GetPixel(1,1));
      this.BackgroundImage = splashImage = (Image) b;
      this.Size = this.splashImage.Size;
   }
   finally
   {
      LockWindowUpdate(IntPtr.Zero);
   }
}
void SetSplashScreenPosition(int w, int h)
{
   this.StartPosition = FormStartPosition.Manual;
   Rectangle ScreenRect = Screen.PrimaryScreen.Bounds;
   this.Location = new Point((ScreenRect.Width - w) / 2, (ScreenRect.Height - h) / 2);
}

If you see a better solution then please advice
Thanks

Wow, It works wonderfully well.
But the Splash Image shows up randomly on the screen. I want it to appear centered.

Here is my code

      public SplashScreen()
        {
           try
           {
              LockWindowUpdate(this.Handle);
              
              this.TopMost = true;
              this.ShowInTaskbar = false;
              this.FormBorderStyle = FormBorderStyle.None;
              this.StartPosition = FormStartPosition.CenterScreen;
              
              this.BackColor = this.TransparencyKey = Color.White;
              Image img = Bitmap.FromFile(LetsYoConfig.SplashFileName);
              Bitmap b = new Bitmap(img);
              b.MakeTransparent(b.GetPixel(1,1));
              this.BackgroundImage = splashImage = (Image) b;
              this.Size = this.splashImage.Size;
           }
           finally
           {
              LockWindowUpdate(IntPtr.Zero);
           }
        }

As you can see I have Splash Screen's start position as Centered (this.StartPosition = FormStartPosition.CenterScreen;) but it is still having random positions.

Please advice
Thanks

Creating Spalsh Screen from an Image in C#

Hi I need to create a Splash Screen from an Image file. The Splash Screen form should be of the same dimensions as the image file. The program should hide the Splash Screen when my MainForm is displayed.

Here is what I'm doing

class SplashScreen : Form
   {
      Image splashImage;
      public SplashScreen()
      {
         
         this.TopMost = true;
         this.ShowInTaskbar = false;
         this.FormBorderStyle = FormBorderStyle.None;
         this.StartPosition = FormStartPosition.CenterScreen;
         
         this.BackColor = this.TransparencyKey = Color.White;
         Image img = Bitmap.FromFile("splash.png");
         Bitmap b = new Bitmap(img);
         b.MakeTransparent(b.GetPixel(1,1));
         this.BackgroundImage = splashImage = (Image) b;
         this.Size = this.splashImage.Size;
      }
   }
class MainForm : Form
{
   public static void main(String[] args)
   {
      // Some Code
      SplashScreen splash = new SplashScreen();
      splash.Show();
         
      MainForm mainForm = new MainForm();
         
      mainForm.Shown += delegate(object o, EventArgs ev)
      {
         splash.Hide();      //Hide and Dispose the Splash Form When mainForm is shown for the first Time
         splash.Dispose();
         mainForm.GetFocus();
      };
      // More Code
   }
}

The Splash Image to be used can be downloaded from http://sukhjinder.cn/splash.png

With the above code I do get the splash screen and the behaviour as expected but before the splash screen is drawn I see a Black Rectangle flashing, with same dimensions as the splash image.

Please suggest. If you have a different approach please go ahead. All I want is to see a nice Splash Screen

Thanks

Post New Requests Here / Ghost Window with Per Window Transparency Settings

« on: June 09, 2007, 12:05 AM »

Hi, I'm Looking for a Free software which can make any Top Level Window Ghost(Clickthrough).
I've tried GhostIt!. Though being a nice Software it has no option to set the transparencey level of individual Ghost window. If I have 2 Ghost Windows then Both have the Same Transparency Levels, which is kind of annoying.

I have tried Making my Windows Ghost using Ghost it and Adjusting Transparency levels using PowerMenu (v 1.5.1). on doing so the Windows lose their Ghost Property.

Please do let me know of the options I may use.

Thanks...

Post New Requests Here / Remove App Button From Taskbar without Minimizing it

« on: June 07, 2007, 12:23 AM »

I am running a program say Wordpad.
Is is available on the Taskbar as Wordpad Button
I want a software which removes Wordpad Button from Taskbar and puts it in the system tray

BUT a Big Big But Here...

The Wordpad should not be minimised to the System tray.

I should be able to continue working on the Wordpad with its Taskbar Button Removed and icon available in the system tray.

The Idea is to remove the button from the taskbar while still being able to work on the application.

Similar Feature is available in Winamp. (see Image Above)

A Discussion is Available at

A Big Thanks to All the People who are Putting in their input
