Fullscreen Form
Hello
Working with .net cf 2.0
The Problem:
I start an Application with a Mainform.
Inside the Mainform i start another form which should work as
a "Welcome Screen".
I want it to be fullscreen with a background picture.
So i derived my own form,
overrides the onpaint and onpainbackground method
set the WindowStyle to Maximized, disable the Minimize and Control Buttons
Set TopMost to true.
But when I show it, it displays the taskbar/start button
After clicking inside the form, it finaly redraws itself in fullscreen mode as wanted!
I tried differnt approaches
- using the SHFullScreen funktion
- Overriding OnLoad and OnActivated
but nothing works
Is this probably a bug in the .net cf 2.0 (its still beta)

here is the Code
First the "StartScreen" Form:

namespace MY_APP
{
public partial class Form_StartScreen : Form
{
Configurator cfg; // a helper class for storing configuration Data
public IRemoteServer theServer; // the Server Object
public Form_StartScreen()
{
theServer = null;
cfg = Configurator.GetInstance();
InitializeComponent();
// Set the address text
label_address.Text = cfg.ServerIPAddr[0] + ":" + (string)cfg.GetGenericValue("ServerPort");
}
protected override void OnPaintBackground(PaintEventArgs e)
{
base.OnPaintBackground(e);
Rectangle sourceRect = new Rectangle(0, 0, Properties.Resources.myapp_startscreen.Width, Properties.Resources.myapp_startscreen.Height);
e.Graphics.DrawImage(Properties.Resources.myapp_startscreen, ClientRectangle,
sourceRect, GraphicsUnit.Pixel);
}
protected override void OnPaint(PaintEventArgs e)
{
Brush br;
StringFormat sf = new StringFormat();
sf.Alignment= StringAlignment.Center;
foreach (Control c in Controls)
{
if (c is Label)
{
Label theLabel = (Label)c;
br = new SolidBrush(theLabel.ForeColor);
e.Graphics.DrawString(theLabel.Text, theLabel.Font, br, theLabel.Bounds, sf);
}
}
base.OnPaint(e);
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
TopMost = true;
this.WindowState = FormWindowState.Maximized;
//Form_StartScreen.SHFullScreen(this.Handle, SHFS_HIDESTARTICON);
}
protected override void OnActivated(EventArgs e)
{
TopMost = true;
this.WindowState = FormWindowState.Maximized;
//Form_StartScreen.SHFullScreen(this.Handle, SHFS_HIDESTARTICON);
Invalidate();
}
private void button_Cancel_Click(object sender, EventArgs e)
{
this.Close();
}
protected override void OnClick(EventArgs e)
{
//This code handles the problem, that sometimes the Button doesn't get the event
if (Control.MousePosition.Y > button_Cancel.Top &&
Control.MousePosition.Y < button_Cancel.Bottom)
if (Control.MousePosition.X > button_Cancel.Left &&
Control.MousePosition.X < button_Cancel.Right)
{
button_Cancel_Click(this, e);
return;
}
Cursor.Current = Cursors.WaitCursor;
// When the User tap on the form I "start the Apllication" connected
// when cancel the User get the "Config Screen" of the MainForm.
int port = Convert.ToInt32((string)cfg.GetGenericValue("ServerPort"));
try
{
theServer = new RemoteTCPServer(cfg.id, cfg.ServerIPAddr[0], port, 0);
}
catch (Exception ex)
{
string errortext = Properties.Resources.Con_Error_Text1 + "\r\n" + ex.Message + "\r\n";
errortext += "\r\n" + Properties.Resources.Con_Error_Text2;
MessageBox.Show(errortext, Properties.Resources.Con_Error_Header, MessageBoxButtons.OK, MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1);
if (theServer != null)
theServer.Dispose();
theServer = null;
}
Cursor.Current = Cursors.Default;
base.OnClick(e);
}
}
}
// This is an extract from the Initalizecomponents Method
/*

and here how i call it in the main form:
| |
//In the constructor I create the form
public MainForm()
{
startscreen = new Form_StartScreen();
startscreen.Click += new EventHandler(startscreen_Click); // This method handles some connecting stuff
/// lots of other configuration
}
// in the onLoad function i "show" the startscreen
// I tried OnActivate , but it also doesnt worked
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
startscreen.Show();
}
