◇[DELPHI]产生鼠标拖动效果
通过MouseMove事件、DragOver事件、EndDrag事件实现，例如在PANEL上的LABEL：
var xpanel,ypanel,xlabel,ylabel:integer;
PANEL的MouseMove事件：xpanel:=x;ypanel:=y;
PANEL的DragOver事件：xpanel:=x;ypanel:=y;
LABEL的MouseMove事件：xlabel:=x;ylabel:=y;
LABEL的EndDrag事件：label ......
制作圆角矩形的窗体：
01.procedure TPortForm.FormCreate(Sender: Tobject);
02.var hr :thandle;
03.begin
04.hr:=createroundrectrgn(0,0,width,height,20,20);
05.setwindowrgn(handle,hr,true);
06.end;
如果不要窗体外框，则使用：
01.procedure TPortForm.FormCreate(Sender: Tobject);
02.var hr :thandl ......

Hand:=CreateToolhelp32Snapshot(TH32CS_SNAPALL,0);
lppe.dwSize := Sizeof(lppe); //初始化
