Problem with Full Screen Application

[dhpanteon]

When the application is in full screen mode (WindowState="Maximized", WindowStyle="None"). This library want work. it will first open the keyboard then automatically close it.

@dhpanteon, what version of Windows are you using?

[dhpanteon]

Windows 10 Enterprise 32-bit.

[maximcus]

Most likely your issue is more about Windows 10 (see #2) then full-screen. Does everything work ok if your app not in full-screen mode?

[dhpanteon]

Yes it works but i need it in full screen mode. Even in my desktop full screen mode works fine.
But in tablet it's not working.

[maximcus]

Your desktop and tablet have different versions of Windows?

[dhpanteon]

It's same.

@dhpanteon, have you tried to find the problem in WPFTabTip source code and fix it yourself?

[dhpanteon]

Yes have gone through your code. I have found the Problem that, it's conflict with in-build behavior of opening Tab Tip keyboard. i guess First it will open OS Behavior keyboard then it'll open WPFTab Tip keyboard. This is only happening with Tab or Mini Pos with no keyboard attach.

i have done some changes that solve my problem

public static void Open()
{
const string TabTipProcessName = "TabTip";
if (EnvironmentEx.GetOSVersion() == OSVersion.Win10)
EnableTabTipOpenInDesctopModeOnWin10();

        if (Process.GetProcessesByName(TabTipProcessName).Count() == 0)
        {
           
            Process.Start(TabTipExecPath);
        }
        else
        {
            try
            {//Close Previously opened keyboard
                if (Process.GetProcessesByName(TabTipProcessName).FirstOrDefault() != null)
                    Process.GetProcessesByName(TabTipProcessName).FirstOrDefault().Kill();
            }

            catch //(Access Error)  Sometime it gives Access Problem 
            { }
            Task.Yield(); // wait for it to close the keyboard

          Process.Start(TabTipExecPath);
        }

        //MessageBox.Show(value.HasValue ? value.Value.ToString() : "null");
        //MessageBox.Show(Process.GetProcessesByName(TabTipProcessName).Count().ToString());
    }


    public static void OpenUndocked()
    {
        const string TabTipDockedKey = "EdgeTargetDockedState";
        const string TabTipProcessName = "TabTip";

        int docked = (int)(Registry.GetValue(TabTipRegistryKeyName, TabTipDockedKey, 1) ?? 1);
        if (docked == 1)
        {
            Registry.SetValue(TabTipRegistryKeyName, TabTipDockedKey, 0);
            foreach (Process tabTipProcess in Process.GetProcessesByName(TabTipProcessName))
            {
                //(Access Error)  Sometime it gives Access Problem 
                try { tabTipProcess.Kill(); } catch { }
            }
        }
        Open();
    }
