Windows mobile 在Windows Mobile 6上隐藏GPRS连接失败通知不会'；他似乎不在工作

我正在将Windows Mobile连接管理器支持添加到我的.NET Compact Framework 3.5应用程序中

我需要向用户隐藏连接错误，我已经阅读了MSDN文档并严格遵守了它（据我所知），但是如果GPRS无法连接，它们仍然会出现

这是我的C代码：

这是ConnMgrConnectionInfo结构的托管包装器：

[StructLayout(LayoutKind.Sequential)]
public sealed class ConnMgrConnectionInfo
{
    Int32 cbSize;                           // DWORD
    public ConnMgrParam dwParams = 0;       // DWORD
    public ConnMgrProxy dwFlags = 0;        // DWORD
    public ConnMgrPriority dwPriority = 0;  // DWORD
    public Int32 bExclusive = 0;            // BOOL
    public Int32 bDisabled = 0;             // BOOL
    public Guid guidDestNet = Guid.Empty;   // GUID
    public IntPtr hWnd = IntPtr.Zero;       // HWND
    public UInt32 uMsg = 0;                 // UINT
    public Int32 lParam = 0;                // LPARAM
    public UInt32 ulMaxCost = 0;            // ULONG
    public UInt32 ulMinRcvBw = 0;           // ULONG
    public UInt32 ulMaxConnLatency = 0;     // ULONG

    // Constructors
    public ConnMgrConnectionInfo()
    {
        cbSize = Marshal.SizeOf(typeof(ConnMgrConnectionInfo));
    }

    public ConnMgrConnectionInfo(Guid destination, ConnMgrPriority priority,  ConnMgrProxy proxy)
        : this()
    {
        guidDestNet = destination;
        dwParams = ConnMgrParam.GuidDestNet;
        dwPriority = priority;
        dwFlags = proxy;
    }

    public ConnMgrConnectionInfo(Guid destination, ConnMgrPriority priority)
        : this(destination, priority, ConnMgrProxy.NoProxy) { }

    public ConnMgrConnectionInfo(Guid destination)
        : this(destination, ConnMgrPriority.UserInteractive) { }
}

与此一起使用的是从connmgr.h定义C标志的枚举

[Flags]
public enum ConnMgrParam : int
{
    GuidDestNet = 0x1,
    MaxCost = 0x2,
    MinRcvBw = 0x4,
    MaxConnLatency = 0x8
}

    [Flags]
public enum ConnMgrProxy : int
{
    NoProxy = 0x0,
    Http = 0x1,
    Wap = 0x2,
    Socks4 = 0x4,
    Socks5 = 0x8,
    SuspendAware = 0x10,
    Registered_Home = 0x20,
    No_Error_Msgs = 0x40,
    WakeOnIncoming = 0x80,
}

public enum ConnMgrPriority
{
    UserInteractive = 0x8000,
    HighPriorityBackground = 0x0200,
    LowPriorityBackground = 0x0008
}

以下是在连接管理器中“拨号”连接的相关PInvoke：

[DllImport("CellCore.dll", EntryPoint = "ConnMgrEstablishConnectionSync", SetLastError = true)]
public static extern int ConnMgrEstablishConnectionSync(ConnMgrConnectionInfo connectionInfo, ref IntPtr connectionHandle, 
    uint dwTimeout, ref ConnMgrStatus dwStatus);

const string scDefaultDestinationNetwork = "My ISP";
const uint dwTimeout = 60000;
ConnMgrStatus status = ConnMgrStatus.Unknown;
IntPtr pointerOut = IntPtr.Zero;
int retVal;

if (ConnectionEntry.DestinationNetwork == null)
{
    ConnectionEntry.DestinationNetwork = scDefaultDestinationNetwork;
}

Guid destinationNetworkGuid = LookupGUIDforNetwork(ConnectionEntry.DestinationNetwork);
ConnMgrConnectionInfo info = new ConnMgrConnectionInfo(destinationNetworkGuid, ConnMgrPriority.HighPriorityBackground, ConnMgrProxy.No_Error_Msgs);
retVal = Win32PInvokes.ConnMgrEstablishConnectionSync(info, ref pointerOut, dwTimeout, ref status);
if (retVal == 0)
{
    ConnectionEntry.Handle = pointerOut;
    ConnectionFailures = 0;
}
else
{
    ConnectionFailures++;
}

最后，以下代码使用正确的设置实例化ConnMgrConnectionInfo，然后从连接管理器请求连接：

[DllImport("CellCore.dll", EntryPoint = "ConnMgrEstablishConnectionSync", SetLastError = true)]
public static extern int ConnMgrEstablishConnectionSync(ConnMgrConnectionInfo connectionInfo, ref IntPtr connectionHandle, 
    uint dwTimeout, ref ConnMgrStatus dwStatus);

const string scDefaultDestinationNetwork = "My ISP";
const uint dwTimeout = 60000;
ConnMgrStatus status = ConnMgrStatus.Unknown;
IntPtr pointerOut = IntPtr.Zero;
int retVal;

if (ConnectionEntry.DestinationNetwork == null)
{
    ConnectionEntry.DestinationNetwork = scDefaultDestinationNetwork;
}

Guid destinationNetworkGuid = LookupGUIDforNetwork(ConnectionEntry.DestinationNetwork);
ConnMgrConnectionInfo info = new ConnMgrConnectionInfo(destinationNetworkGuid, ConnMgrPriority.HighPriorityBackground, ConnMgrProxy.No_Error_Msgs);
retVal = Win32PInvokes.ConnMgrEstablishConnectionSync(info, ref pointerOut, dwTimeout, ref status);
if (retVal == 0)
{
    ConnectionEntry.Handle = pointerOut;
    ConnectionFailures = 0;
}
else
{
    ConnectionFailures++;
}

此外，以下注册表设置设置为0以隐藏连接成功和断开连接消息：

HKEY_CURRENT_USER\ControlPanel\Notifications\{8ddf46e7-56ed-4750-9e58-afc6ce486d03}\Options (0)
HKEY_CURRENT_USER\ControlPanel\Notifications\{8ddf46e8-56ed-4750-9e58-afc6ce486d03}\Options (0)

现在，当代码触发时，连接错误仍然会在我们的kiosk风格的应用程序上弹出，允许用户点击设置并访问底层操作系统及其设置

有人能看出我做错了什么吗？

以下是我的解决方案：

将以下注册表设置重新指向您自己的自定义exe：

HKEY\U LOCAL\U MACHINE\Software\Microsoft\Shell\Rai \：MSREMNET\1

它默认为\Windows中名为RemNet.exe的程序

如果传递了参数-RASERROR，则会弹出一个气球

我编写了自己的exe，有选择地忽略带有-RASERROR的调用，并将其余调用传递到原始RemNet：

#if DEBUG
            string message = "OurRemNet called with:\r\n";

            foreach (string arg in args)
            {
                message += arg + "\r\n";
            }

            MessageBox.Show(message);

            string repeatparams = "";

            foreach (string arg in args)
            {
                repeatparams += arg + " ";
            }

            Process.Start(@"\Windows\RemNet.exe", repeatparams);
#else
                bool forwardToRemNet = true;

                foreach(string arg in args)
                {
                    if (arg == "-RASERROR")
                    {
                        forwardToRemNet = false;
                    }
                }

                if (forwardToRemNet)
                {
                    string repeatparams = "";

                    foreach (string arg in args)
                    {
                        repeatparams += arg + " ";
                    }
                    Process.Start(@"\Windows\RemNet.exe", repeatparams);
                }
#endif

我使用DEBUG开关生成一个EXE，告诉我发生了什么（调试），或者只是屏蔽ras错误（发布）

我使用DEBUG开关构建一个EXE，告诉我发生了什么（DEBUG），或者只是屏蔽ras错误（RELEASE）

作为旁白，我想出了一个解决方法。我只是延迟了检查连接是否正常的计时器，直到软件启动3分钟后才启动。不会隐藏任何其他故障，但会在引导后隐藏保证的故障。不，仍然会弹出间歇性错误消息。作为旁白，我想出了一个解决方法。我只是延迟了检查连接是否正常的计时器，直到软件启动3分钟后才启动。不会隐藏任何其他故障，但会在引导后隐藏保证的故障。不会，仍会弹出间歇性错误消息。
