c# - Drog and Drop TableLayoutPanel in a panel? -


i'm trying drag , drop tablelayoutpanel in panel using winforms/c#, drag of tablelayout works problem tablelayoutpanel droped doesn't appear !! solution please ??

private void registration_load(object sender, eventargs e) {         panel2.allowdrop = true;      tablelayoutpanel1.allowdrop = true;      panel2.dragenter += panel2_dragenter;         panel2.dragdrop += panel2_dragdrop;      tablelayoutpanel1.mousedown += tablelayoutpanel1_mousedown; }     private void panel2_dragenter(object sender, drageventargs e) {     e.effect = dragdropeffects.move; }  private void panel2_dragdrop(object sender, drageventargs e) {      ((tablelayoutpanel)e.data.getdata(typeof(tablelayoutpanel))).parent (panel)sender;                 } private void tablelayoutpanel1_mousedown(object sender, mouseeventargs e) {      tablelayoutpanel1.dodragdrop(tablelayoutpanel1, dragdropeffects.move); }

the code inadequate, you'll need @ least set location property of dropped tlp ensure within panel bounds and/or located @ mouse cursor. , z-order matters, setting parent property puts @ bottom can overlapped other controls in panel, need bringtofront().

try this:

    private void panel2_dragenter(object sender, drageventargs e) {         if (e.data.getdatapresent(typeof(tablelayoutpanel))) e.effect = dragdropeffects.move;     }      private void panel2_dragdrop(object sender, drageventargs e) {         var tlp = (tablelayoutpanel)e.data.getdata(typeof(tablelayoutpanel));         tlp.location = panel2.pointtoclient(new point(e.x, e.y));         tlp.parent = panel2;         tlp.bringtofront();     }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
