[DELPHI]网络邻居复制文件
uses shellapi;
copyfile(pchar('newfile.txt'),pchar('//computername/direction/targer.txt'),false);[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.left:=xpanel-xlabel;label.top:=ypanel-ylabel;
[DELPHI]取得WINDOWS目录
uses shellapi;
var windir:array[0..255] of char;
getwindowsdirectory(windir,sizeof(windir));或者从注册表中读取,位置:
HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionSystemRoot键,取得如:C:WINDOWS
[DELPHI]在FORM或其他容器上画线
var x,y:array [0..50] of integer;
canvas.pen.color:=clred;
canvas.pen.style:=psDash;
form1.canvas.moveto(trunc(x[i]),trunc(y[i]));
form1.canvas.lineto(trunc(x[j]),trunc(y[j]));[DELPHI]字符串列表使用
var tips:tstringlist;
tips:=tstringlist.create;
tips.loadfromfile('filename.txt');
edit1.text:=tips[0];
tips.add('last line addition string');
tips.insert(1,'insert string at NO 2 line');
tips.savetofile('newfile.txt');
tips.free;[DELPHI]简单的剪贴板操作
