.NET CF ListView 不支援 OnClick

.NET CF 中的 ListView 不支援 ItemOnClick, OnClick 等事件，
所以若要取得使用者點選的 ListViewItem 得用 SelectedIndexChanged 來替代，
範例如下：

private void lv_SelectedIndexChanged(object sender, EventArgs e)
{
    if (lv.SelectedIndices.Count > 0)
    {
        ListViewItem lvi = lv.Items[lv.SelectedIndices[0]];
        MessageBox.Show(lvi.SubItems[0].Text);
    }
}

Web Service：無法序列化 DataTable。DataTable 名稱未設定。

使用 .NET Framework 2.0 的 Web Service 傳遞 DataTable 參數，
Runtime 會報錯：無法序列化 DataTable。DataTable 名稱未設定。


只要設定以下屬性即可解決：

dtMyTable.TableName = "MyTableName";

C# get a string from C++ DLL

C++ DLL ：

TCHAR g_awcMessage[] = L"Hello中文"; 

char g_aszMessage[] = "Hello中文"; 

 

extern "C" __declspec(dllexport) TCHAR* __stdcall GetHelloL() 

{  

 return g_awcMessage;  

} 

 

extern "C" __declspec(dllexport) CHAR* __stdcall GetHello() 

{  

 return g_aszMessage; 

} 

 

extern "C" __declspec(dllexport) int __stdcall GetInt() 

{  

 return 100; 

}

C# P/Invoke：

[DllImport("gpDll.dll")] 

public static extern IntPtr GetHello(); 

 

[DllImport("gpDll.dll")] 

public static extern IntPtr GetHelloL(); 

 

[DllImport("gpDll.dll")] 

public static extern int GetInt(); 

 

 

private void button1_Click(object sender, EventArgs e) 

{ 

            // Not support in CF 

            //Marshal.PtrToStringAnsi 

            //Marshal.PtrToStringAuto 



            // Multibytes 會變成亂碼 

            string str =  Marshal.PtrToStringUni(GetHello()); 

    

            // Wide Character 顯示正常 

            string strL = Marshal.PtrToStringUni(GetHelloL()); 



           int n = GetInt(); 

}

SendKeys for .NETCF

Because System.Windows.Forms SendKeys does not support in .NETCF,
So I have to implement it thru APIs,

here is the solutions: SendInput, keybd_event, PostKeybdMessage and SendMessage

        [DllImport("coredll.dll", SetLastError = true)]

        //[DllImport("user32.dll", SetLastError = true)]

        static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);



        [DllImport("coredll", SetLastError = true)]

        //[DllImport("user32.dll", SetLastError = true)]

        public static extern IntPtr FindWindow(string _ClassName, string _WindowName);



        [DllImport("coredll", SetLastError = true)]

        //[DllImport("user32.dll")]

        private static extern bool SetForegroundWindow(IntPtr hWnd);



        public static void SendIt()

        {

            IntPtr ip = FindWindow("notepad", null);





            SetForegroundWindow(ip);



            const int KEYEVENTF_KEYUP = 0x2;



            const int KEYEVENTF_KEYDOWN = 0x0;



            byte VK_TAB = 0x0D;



            keybd_event(VK_TAB, 0, KEYEVENTF_KEYDOWN, 0);

            keybd_event(VK_TAB, 0, KEYEVENTF_KEYUP, 0);

       }

Emulate mouse action in .NETCF

There are some ways to do it,

SendMessage API:

            //Find topmost window of another application

            IntPtr parentWnd = WIN32.Window.FindWindow(null, "Form2");



            //Find the button

            IntPtr hButton = WIN32.Window.FindWindowEx(parentWnd, IntPtr.Zero, null, "Target");



            //Click the target button

            WIN32.Window.SendMessage(hButton, Window.WM.WM_LBUTTONDOWN, IntPtr.Zero, IntPtr.Zero);

            WIN32.Window.SendMessage(hButton, Window.WM.WM_LBUTTONUP, IntPtr.Zero, IntPtr.Zero);

 



mouse_event API:



        [DllImport("coredll.dll", SetLastError = true)]

        static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);



        [DllImport("user32.dll")]

        static extern bool SetCursorPos(int X, int Y);



        public enum MouseEventFlags

        {

            LEFTDOWN = 0x00000002,

            LEFTUP = 0x00000004,

            MIDDLEDOWN = 0x00000020,

            MIDDLEUP = 0x00000040,

            MOVE = 0x00000001,

            ABSOLUTE = 0x00008000,

            RIGHTDOWN = 0x00000008,

            RIGHTUP = 0x00000010

        }

        void ClickIt()

        {

            SetCursorPos(400, 10);

            mouse_event((int)(MouseEventFlags.LEFTDOWN), 0, 0, 0, 0);

            mouse_event((int)(MouseEventFlags.LEFTUP), 0, 0, 0, 0);

        }

How to increase volume of application sound on pocket pc

Q:
My application plays different sounds in different conditions..all working fine. Only trouble is when incoming call alert is there , sound produced by device (RINGTONE) is loud but sound played by application (parallely to Ringtone) is very low. Does ringtone have a higher priority for the device speaker than our application sound.

A:
Yes in effect the ringtone sound has a higher gain setting than your application audio when an incoming phone call is detected. This is implemented by the concept of "classes".

Further details including details of how you can alter this behaviour can be found in the Windows CE Multimedia Team Blog in an article titled "The WaveDev2 GainClass Implementation" available at
http://blogs.msdn.com/medmedia/archive/2007/01/04/the-wavedev2-gainclass-implementation.aspx
