C# winapi SendMessage 或 PostMessage 怎麽送一啊,如F1 setText用了但是送不怎麽送一啊
[code=C#]
void fun()
{

IntPtr PanentWindow = winapi.FindWindow(null, "计算器");
if (PanentWindow != IntPtr.Zero)
{

IntPtr ChileWindow = winapi.FindWindowEx(PanentWindow,IntPtr.Zero,"Edit",null);

if (ChileWindow != IntPtr.Zero)
{
MessageBox.Show("找到窗口");
winapi.SendMessage(ChileWindow, WM_SETTEXT, "Edit", "10005");
}
}code]

[解决办法]
public struct COPYDATASTRUCT
{
public IntPtr dwData;
public int cbData;
[MarshalAs(UnmanagedType.LPStr)]
public string lpData;
}

[DllImport("User32.dll", EntryPoint = "SendMessage")]
private static extern int SendMessage(
IntPtr hWnd, // handle to destination window
int Msg, // message
int wParam, // first message parameter
ref COPYDATASTRUCT lParam // second message parameter
);



COPYDATASTRUCT cds;
cds.dwData = (IntPtr)100;
cds.lpData = "Test Message";
cds.cbData = 14;

SendMessage(hwnd_win, WM_SETTEXT, 0, ref cds);
