IntPtr WndProc找不到覆盖c#的合适方法
本文关键字:方法 WndProc 找不到 覆盖 IntPtr | 更新日期: 2023-09-27 17:59:39
我试图在获胜表单应用程序中覆盖此WndProc
,但出现错误IntPtr WndProc no suitable method found to override
。我的代码如下
protected override IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
{
if (msg == NativeCalls.APIAttach && (uint)lParam == NativeCalls.SKYPECONTROLAPI_ATTACH_SUCCESS)
{
// Get the current handle to the Skype window
NativeCalls.HWND_BROADCAST = wParam;
handled = true;
return new IntPtr(1);
}
// Skype sends our program messages using WM_COPYDATA. the data is in lParam
if (msg == NativeCalls.WM_COPYDATA && wParam == NativeCalls.HWND_BROADCAST)
{
COPYDATASTRUCT data = (COPYDATASTRUCT)Marshal.PtrToStructure(lParam, typeof(COPYDATASTRUCT));
StatusTextBox.Items.Add(data.lpData + Environment.NewLine);
// Check for connection
//if (data.lpData.IndexOf("CONNSTATUS ONLINE") > -1)
// ConnectButton.IsEnabled = false;
// Check for calls
IsCallInProgress(data.lpData);
handled = true;
return new IntPtr(1);
}
return IntPtr.Zero;
}
任何人都可以指引我所缺少的东西。感谢
您的方法签名不正确,您正在重写的Form.WndProc
返回void
。
protected virtual void WndProc(ref Message m)
我不知道你从哪里得到的代码,也许是C++的端口?但是它不适用于WinForms表单。
