在一个模态窗口，想要在本窗口中，通过调用win32，来使另一个窗口的控件进行移动（本身可以通过鼠标中键按下，移动，控件可以拖动）
private void Window_MouseDown(object sender, MouseButtonEventArgs e)
{
if (e.MiddleButton != MouseButtonState.Pressed) return;
const int WM_MBUTTONDOWN = 0x0207;
IntPtr last = PmSoft.Common.Controls.RevitMethod.RevitHandle.RevitViewHandle;
POINT mp = new POINT(0, 0);
bool isGet = GetCursorPos(out mp);
if (isGet)
{
int xPosition = mp.X;
int yPosition = mp.Y << 16;
SendMessage(last, WM_MBUTTONDOWN, (IntPtr)(0x00000010), (IntPtr)(xPosition + yPosition));
e.Handled = true;
}
}
private void Window_MouseMove(object sender, MouseEventArgs e)
{
if (e.MiddleButton != MouseButtonState.Pressed) return;
const int WM_MOUSEMOVE = 0x0200;
IntPtr last = PmSoft.Common.Controls.RevitMethod.RevitHandle.RevitViewHandle;
POINT mp = new POINT(0, 0);
bool isGet = GetCursorPos(out mp);
if (isGet)
{
int xPosition = mp.X;
int yPosition = mp.Y << 16;
SendMessage(last, WM_MOUSEMOVE, (IntPtr)(0x00000010), (IntPtr)(xPosition + yPosition));
}
}
private void Window_MouseUp(object sender, MouseButtonEventArgs e)
{
if (e.MiddleButton == MouseButtonState.Pressed) return;
const int WM_MBUTTONUP = 0x0208;
IntPtr last = PmSoft.Common.Controls.RevitMethod.RevitHandle.RevitViewHandle;
POINT mp = new POINT(0, 0);
bool isGet = GetCursorPos(out mp);
if (isGet)
{
int xPosition = mp.X;
int yPosition = mp.Y << 16;
//PmSoft.Common.CommonClass.Win32Helper.Win32.SetCapture(last);
SendMessage(last, WM_MBUTTONUP, (IntPtr)(0x00000000), (IntPtr)(xPosition + yPosition));
e.Handled = true;
}
}
发送了鼠标中键按下，移动，和中键抬起事件，但是没有效果，不知道哪里出问题了。
对win32不太熟悉，请大家帮忙看看。
一般是 API 函数的参数没处理好。
然后按下和移动、抬起之间要加 5ms 的延迟。
这里有写好的代码，你参考下
