Firstly, let us talk about what we can get benefit when we develop WM application by VS 2010.Of course, we had to talk about the Windows 7’s official sale and Visual Studio 2010 on-line, both of which belong to a series of products released by Microsoft. These new products will have high levels of integration and closer mutual support. For a developer, Development of uniform standards will bring not only convenience, but also high efficiency.
Take “Hello World” as an example. We just need to change PSTE of the application under Win32 edition as LPSTR, the program can be compiled and on.
Code:
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPTSTR lpCmdLine, int nShowCmd)
{
MessageBox(NULL, TEXT(“Hello, Windows Mobile!”), TEXT(“HelloMsg”), 0);
return 0;
}
From this, we can find that Windows Mobile development is the same as the general Windows program development. We can get a handle on it without hard learning process. And we can use our familiar language.
With intelligence handset more and more popular and coupled with the arrival of 3G area, the demand to write the mobile applications will increase much.
Now, let us see a code in windows mobile by using c# to achieve cmnet link:
public bool Connectcmnetmethod(Guid destGuid, bool exclusive, bool mode)
{
{
connInfo.cbSize = (uint)Marshal.SizeOf(connInfo);
connInfo.dwParams = 0×1;//CONNMGR_PARAM_GUIDDESTNET;
connInfo.dwPriority = 0×08000;
connInfo.dwFlags = 0×1 | 0×2 | 0×4 | 0×8;//0;
connInfo.bExclusive = 0;// exclusive;
connInfo.bDisabled = 0;// false;
connInfo.guidDestNet = destGuid;
connInfo.hWnd = this.Handle;
if (mode == true)
{
result = ConnMgrEstablishConnectionSync(ref connInfo, ref hConnection, 10000, out dwStatus);
if (result != 0) MessageBox.Show(result.ToString(“X”), dwStatus.ToString(“X”));
return result == 0;
}
return false;
}
}
public struct CONNMGR_CONNECTIONINFO
{
public uint cbSize;
public uint dwParams;
public uint dwFlags;
public uint dwPriority;
public int bExclusive;
public int bDisabled;
public Guid guidDestNet;
public IntPtr hWnd;
public uint uMsg;
public uint lParam;
public uint ulMaxCost;
public uint ulMinRcvBw;
public uint ulMaxConnLatency;
}
[DllImport("cellcore.dll", EntryPoint = "ConnMgrEstablishConnectionSync", SetLastError = true)]
internal static extern int ConnMgrEstablishConnectionSync(ref CONNMGR_CONNECTIONINFO pConnInfo, ref IntPtr phConnection, int dwTimeout, out int dwStatus);
[DllImport("cellcore.dll", EntryPoint = "ConnMgrEstablishConnection", SetLastError = true)]
internal static extern int ConnMgrEstablishConnection(ref CONNMGR_CONNECTIONINFO pConnInfo, ref IntPtr phConnection);
[DllImport("cellcore.dll", EntryPoint = "ConnMgrReleaseConnection", SetLastError = true)]
internal static extern int ConnMgrReleaseConnection(IntPtr hConnection, int lCache);
[DllImport("coredll.dll")]
private static extern int CloseHandle(IntPtr hObject);
[DllImport("Coredll.dll", EntryPoint = "GetLastError", SetLastError = true)]
internal static extern int GetLastError();
private void menuItem1_Click(object sender, EventArgs e)
{
MessageBox.Show(Connect(new Guid(“7022E968-5A97-4051-BC1C-C578E2FBA5D9″), false, true).ToString());
}
Under Visual Studio 2010, it is very easy to write the simple, stable, efficient procedure. However, there are some problems .For example, the mobile have great resource consumption, and need to install the mobile version of the Framework program. The market share of the windows mobile is low, and there won’t be much demand to write the program in the short time.
