C # winCE5.0 development right-click results Solution

I used VS2008 to develop the C # Language wince program. I found that the program could not be captured by the Right-click, and the Collector did not respond. I found a c ++ version on the Internet and couldn't understand it, below I will provide a solution for Implementing the Right-click effect in C #. Please optimize it a lot. First, the control ContextMenu and Timer set contextMenu1 to implement right-click in the dataGrid, and the event datagrid?mousedown presses the mouse button event. Code [csharp] public int _ x; public int _ y; private void datagrid=mousedown (object sender, MouseEventArgs e) {System. drawing. point Pt = new Point (e. x, e. y); DataGrid. hitTestInfo Ht = maid (Pt. x, Pt. y); // this. maid = new maid (Ht. row, Ht. column); // this. dataGrid1.Select (Ht. row); if (Ht. row> = 0 & Ht. column> = 0) {_ x = e. X + 2; // record the current coordinate of the mouse _ y = e. Y + 1; // same as above (priorP Previously declared oint) 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; // enable timer }}internal struct SHRGINFO {public int cbSize; public IntPtr hwndClient; Public int ptDownX; public int ptDownY; public SHRGFLags dwFlags;} [Flags] internal enum SHRGFLags {blocks = 0x00000001, shrg_policyparent = 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 GetActive Window (); DataGrid. HitTestInfo I used it for the first time. After the coordinates are passed in, I can know which column is on the left and whether there is any data. I will make the following judgments to display the data. Ret = 1000 circles in exactly one [DllImport ("aygshell")] extern private static int SHRecognizeGesture (ref SHRGINFO shr); [DllImport ("coredll. dll ", SetLastError = true)] public static extern IntPtr GetActiveWindow (); enable the collector DLL interface program. MousePosition. X-2 The current mouse-2 is the control circle. It is not built in the mouse. I have adjusted it, And _ X _ Y will be used in time. Timer1 event. If the right-click menu is displayed here, because the resource is not released, an error is reported. Only the next event can be started. I wrote it in timer1_Tick, use timer1.Enabled = true to enable the event [csharp] private void timerjavastick (object sender, EventArgs e) {string pids = this. dataGrid1 [this. dataGrid1.CurrentRowIndex, 0]. toString (); if (pids! = "") {ContextMenu1.Show (dataGrid1, new Point (_ x, _ y); // The context menu timer1.Enabled = false;} appears. You need to write the control dataGrid1 this bound to contextmenu1. dataGrid1 [this. dataGrid1.CurrentRowIndex, 0]. toString (); to obtain a column in the selected row.
