用VS2008开发C#语言wince程序，发现程序里右键捕获不到，采集器上点也没反应，上网查好像有个c++版本的，看不懂啊，下面我给出C#实现右键效果的解决方案，请各位多多优化。
首先控件ContextMenu 和 Timer
设置contextMenu1
在dataGrid里实现右键点击，事件dataGrid1_MouseDown 按下鼠标按钮事件。
上代码
public int _x;
public int _y;
private void dataGrid1_MouseDown(object sender, MouseEventArgs e)
{
System.Drawing.Point Pt = new Point(e.X, e.Y);
DataGrid.HitTestInfo Ht = dataGrid1.HitTest(Pt.X, Pt.Y);
//this.dataGrid1.CurrentCell = new DataGridCell(Ht.Row, Ht.Column);
//this.dataGrid1.Select(Ht.Row);
if (Ht.Row >= 0 && Ht.Column >= 0)
{
_x = e.X + 2;//记录鼠标当前坐标
_y = e.Y + 1;//同上（priorPoint前面已经声明）
SHRGINFO shr = new SHRGINFO();
shr.cbSize = Marshal.SizeOf(typeof(SHRGINFO));
shr.dwFlags = SHRGFLags.SHRG_RETURNCMD;
shr.ptDownX = MousePosition.X - 2;
shr.ptDownY = MousePosition.Y - 8;
shr.hwndClient = GetActiveWindow();
int ret = SHRecognizeGesture(ref shr);
if (ret == 1000)
{
timer1.Enabled = true;//开启计时器
}
}
}
internal struct SHRGINFO
{
public int cbSize;
public IntPtr hwndClient;
public int ptDownX;
public int ptDownY;
public SHRGFLags dwFlags;
}
[Flags]
internal enum SHRGFLags
{
SHRG_RETURNCMD = 0x00000001,
SHRG_NOTIFYPARENT = 0x00000002,
SHRG_LONGDELAY = 0x00000008,
SHRG_NOANIMATION = 0x00000010,
}
[DllImport("aygshell")]
extern private static int SHRecognizeGesture(ref SHRGINFO shr);
[DllImport("coredll.dll", SetLastError = true)]
public static extern IntPtr GetActiveWindow();
DataGrid.HitTestInfo
ret == 1000
圆圈正好一圈
[DllImport("aygshell")]
extern private static int SHRecognizeGesture(ref SHRGINFO shr);
[DllImport("coredll.dll", SetLastError = true)]
public static extern IntPtr GetActiveWindow();
启用采集器DLL接口程序。
MousePosition.X - 2
当前鼠标-2这个是控制圆圈的，不在鼠标中建，我给调了调，
_X _Y 会在时间里用到。
timer1
的事件，如果在此弹出右键菜单因为资源没有被释放，所以会报错的，只能启动下一个事件，我写在了
timer1_Tick里，并使用
timer1.Enabled =
true
启用事件
private void timer1_Tick(object sender, EventArgs e)
{
string pids = this.dataGrid1[this.dataGrid1.CurrentRowIndex, 0].ToString();
if (pids != "")
{
contextMenu1.Show(dataGrid1, new Point(_x, _y));//弹出上下文菜单
timer1.Enabled = false;
}
}
要写上
contextMenu1
绑定的控件
dataGrid1
this.dataGrid1[this.dataGrid1.CurrentRowIndex, 0].ToString();可获得当前选中行某列。
