It was good, but quality suffers code
|

|
|
|
Thank you so much!! Awesome code, I have been trying to do this for days!
Thank you!
|

With the thousand solutions I tried, your one was the only one which worked (for Windows CE 5.0, not PocketPC !!!!!).
So thanks a lot for stopping my pain in the A...

|
Thanks for the code, this is true fullscreen!
|
|
|
|
|
The most full screen applictions are designed as not using the system utilities (SIP or menu).
So, we do not need to move the Task/Input Windows. Just to set the size and location to full all workarea, and remove the menu if it exist.
|
|
|
|
|
You can do this with pure .net
Set the following properties of the form (in designer or in the code):
FormBorderStyle = FormBorderStyle.None;
WindowState = FormWindowState.Maximized;
|
|
|
|
|
I have had the full screen problem also and that C# code worked when I wanted to hide the taskbar, but when I tried to recover the taskbar it didn't.
But I found this very easy way:
In desing mode I have WindowState: Normal.
Then I put this code below in Form's constructor after InitializeComponent();
<br />
WindowState = FormWindowState.Maximized;<br />
And now when you open the Form it opens in full screen.

Hi all,
I know with should NEVER happen but if my application crash (exception not catched for example), the FSEngine remains active.
It means that the upper part of my application is displayed instead of the menu bar on a PPC 2003. The only way to get it back is to warm boot the mobile.
Any idea on how to skip that problem ?
I know maybe I could start my application again and stop it correctly; the code to disable FSEngine would then be called BUT the problem is that I don't have access to the start menu due to that issue
Maybe someone found a good practice to avoid that one.
Thanks for sharing experience.

Thanks, i just translate, all the work has been done by hackzai.
For your problem:
- what means it does not work ?
- Moreover, why do you call fs.DoFullScreen(true) twice ?
- What changes have you made between the both code ?
I remember that i was using this code in OnLoad(); i will verify with my previous collegues. Have you try on another event like OnShow or OnVisible (if they exist, i can't remember).
Regards,
AB

I try to retrieve my old code where i use it in OnLoad().
I remember that i use it in OnActivate() or something like that. Let's try this.
Moreover, does it works if you leave the orginal code (without your modifications) ?

Hi,
someone has tried to use it with C#?
I get some error, could someone help me please?
Thanks in advance

An application creates a FullScreen form by setting its WindowState to Maximized as follows:
form.WindowState = FormWindowState.Maximized;
If there is a MenuBar (and / or a ToolBar on Pocket PC) attached to the Form, then it can't be made FullScreen.
On version 1.0 of the .NET Compact Framework on Pocket PC, to create a FullScreen application the WindowState property must be set inside the Form's OnLoad.
|
|
|
|
|
right.
.net CF can do it easy. why use other class or library?
|
|
|
|
|
I tried to create a full screen window on a Windows CE 5.0* based PocketPC. Maximizing the window still left the taskbar on the bottom of the desktop. I tried SHFullScreen but it didn't work like expected (maybe my fault). The only thing that worked is this class.
* Please note that Windows CE 5.0 and Windows Mobile 5 are somewhat different. Native Windows CE 5.0 looks like a real Windows Desktop.

Can you please tell me why isnt it working

Good job. I can't believe this.
Yesterday I solved my full screen problem on Windows CE (It took me 6 hours to get the
glue) I've done it in VB with Form.Size and Form.Location. It was an odyssey first I tried
Form.FromBorderstile, which don't work. Then I tried to get the Window handle of the Taskbar, and hide the window, which left a kind of shadow window of the Taskbar. At last I tried to relocate the Window and it worked, and now this. =

I have the very same problem on a Windows Mobile 5.0 Pocket PC Phone edition. You think you could explain this a little more in detail? I've tried the rest of the suggestions here and can't get it to work.
