Windows Task Bar

Thread rating:  |
Greg - 22 Sep 2007 19:32 GMT I have an application I'm developing in VB.Net 2005. This is going to be a trouch screen application. What I want to do is when my applicaiton loads I want it to take up the entire screen, including the Windows Task Bar. (I don't know if I'm using the correct term here, so let me explain. I want to have the bar on the button of the Windows XP screen that contains a Icon/Button for each application that is running, to be hidden from view.). So, when you look at the screen all you see is my application and nothing else. The only way the bar would re-appear is after the user has quit the application.
Thanks, Greg
Stevanich - 23 Sep 2007 07:50 GMT Greg,
You most likely will want to make some OS customizations to get the results you want, such as hiding the Start Bar.
Hope this helps,

The article below provided the detailed sample code and steps to complete the task you wanted: "How to make Windows Form app truly Full Screen (and to hide Taskbar) in C#?" http://www.codeproject.com/useritems/FullScreenDotNetApp.asp
To translate the code snippet into VB.net, you may use the translator below(note: it is not perfect, but should save you 90% of the work): http://www.aspalliance.com/aldotnet/examples/translate.aspx
Hope this helps.

Greg - 27 Sep 2007 21:16 GMT I took a look at the sites you included. Plus, I copied the C# code into the converter web-site and tried to convert the code to VB.Net. It didn't seem to do a very good job at all, because I was completely lost on figuring out how to replciate that code in VB.Net. What I really need is a VB.Net sample code block. I don't understand the first thing about C#.
Thanks for helping

Thank you for the feedback.
Yes, this C# to VB.net is not very good. Unfortunately, I can not find a VB.net sample yet.
Can you tell me which code you can not understand how to translate into VB.net? I can help you to get it done. Thanks.

Greg - 29 Sep 2007 00:32 GMT I have managed to get my application to cover the whole screen with just the TaskBar. Now, just need to go one step further and hide the TaskBar.
Here is the C# Code.
<PRE lang=cs id=pre3 style="MARGIN-TOP: 0px">/// <summary> /// Selected Win API Function Calls /// </summary>
public <A class=iAs style="FONT-WEIGHT: normal; FONT-SIZE: 100%; PADDING-BOTTOM: 1px; COLOR: darkgreen; BORDER-BOTTOM: darkgreen 0.07em solid; BACKGROUND-COLOR: transparent; TEXT-DECORATION: underline" href="#" target=_blank itxtdid="4499192">class</A> WinApi { [DllImport(”user32.dll”, EntryPoint = “GetSystemMetrics”)] public static extern int GetSystemMetrics(int which);
[DllImport(”user32.dll”)] public static extern void SetWindowPos(IntPtr hwnd, IntPtr hwndInsertAfter, int X, int Y, int width, int height, uint flags);
private const int SM_CXSCREEN = 0; private const int SM_CYSCREEN = 1; private static IntPtr HWND_TOP = IntPtr.Zero; private const int SWP_SHOWWINDOW = 64; // 0×0040
public static int ScreenX { get { return GetSystemMetrics(SM_CXSCREEN);} }
public static int ScreenY { get { return GetSystemMetrics(SM_CYSCREEN);} }
public static void SetWinFullScreen(IntPtr hwnd) { SetWindowPos(hwnd, HWND_TOP, 0, 0, ScreenX, ScreenY, SWP_SHOWWINDOW); } }
/// <summary> /// Class used to preserve / restore / maximize state of the form /// </summary> public class FormState { private FormWindowState winState; private FormBorderStyle brdStyle; private bool topMost; private Rectangle bounds;
private bool IsMaximized = false;
public void Maximize(Form targetForm) { if (!IsMaximized) { IsMaximized = true; Save(targetForm); targetForm.WindowState = FormWindowState.Maximized; targetForm.FormBorderStyle = FormBorderStyle.None; targetForm.TopMost = true; WinApi.SetWinFullScreen(targetForm.Handle); } }
public void Save(Form targetForm) { winState = targetForm.WindowState; brdStyle = targetForm.FormBorderStyle; topMost = targetForm.TopMost; bounds = targetForm.Bounds; }
public void Restore(Form targetForm) { targetForm.WindowState = winState; targetForm.FormBorderStyle = brdStyle; targetForm.TopMost = topMost; targetForm.Bounds = bounds; IsMaximized = false; } } </PRE> public partial class MaxForm : Form { FormState formState = new FormState();
public MaxForm() { InitializeComponent(); }
private void button1_Click(object sender, EventArgs e) { formState.Maximize(this); }
private void button2_Click(object sender, EventArgs e) { formState.Restore(this); } } This is it. Some of it I can figure out, but as a whole that VB.Net Converter made it worse, not better.
Thanks for you help.

Regarding this code snippet, I have helped you to translate it. Yes, it seems the converter tool will use the old style VB6 syntax to for the p/invoke APIs. Anyway, I have converted it with the new VB.net syntaxt:
Imports System.Runtime.InteropServices Public Class Form1 Class WinApi <DllImport("user32.dll", CharSet:=CharSet.Auto)> _ Public Shared Function GetSystemMetrics(ByVal nIndex As Integer) As Integer End Function
<DllImport("user32.dll", CharSet:=CharSet.Auto)> _ Public Shared Function SetWindowPos(ByVal hWnd As IntPtr, ByVal hWndInsertAfter As IntPtr, ByVal x As Integer, ByVal y As Integer, ByVal cx As Integer, ByVal cy As Integer, ByVal flags As Integer) As Boolean End Function
Private Shared SM_CXSCREEN As Integer = 0 Private Shared SM_CYSCREEN As Integer = 1 Private Shared HWND_TOP As IntPtr = IntPtr.Zero Private Shared SWP_SHOWWINDOW As Integer = 64 '
Public Shared ReadOnly Property ScreenX() As Integer Get Return GetSystemMetrics(SM_CXSCREEN) End Get End Property
Public Shared ReadOnly Property ScreenY() As Integer Get Return GetSystemMetrics(SM_CYSCREEN) End Get End Property
Public Shared Sub SetWinFullScreen(ByVal hwnd As IntPtr) SetWindowPos(hwnd, HWND_TOP, 0, 0, ScreenX, ScreenY, SWP_SHOWWINDOW) End Sub 'SetWinFullScreen End Class 'WinApi
Private frmState As New FormState()
Public Class FormState Private winState As FormWindowState Private brdStyle As FormBorderStyle Private topMost As Boolean Private bounds As Rectangle
Private IsMaximized As Boolean = False
Public Sub Maximize(ByVal targetForm As Form) If Not IsMaximized Then IsMaximized = True Save(targetForm) targetForm.WindowState = FormWindowState.Maximized targetForm.FormBorderStyle = FormBorderStyle.None targetForm.TopMost = True WinApi.SetWinFullScreen(targetForm.Handle) End If End Sub 'Maximize
Public Sub Save(ByVal targetForm As Form) winState = targetForm.WindowState brdStyle = targetForm.FormBorderStyle topMost = targetForm.TopMost bounds = targetForm.Bounds End Sub 'Save
Public Sub Restore(ByVal targetForm As Form) targetForm.WindowState = winState targetForm.FormBorderStyle = brdStyle targetForm.TopMost = topMost targetForm.Bounds = bounds IsMaximized = False End Sub 'Restore End Class 'FormState
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click frmState.Maximize(Me) End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click frmState.Restore(Me) End Sub End Class
Finally, for such VB.net syntax issue, I would recommend you to post in microsoft.public.dotnet.languages.vb because there will be more VB.net developers there.
Hope this helps.
