使用JavaScript：
在<head></head>之间插入下列代码
<script language="JavaScript">
drag = 0
move = 0function init() {
window.document.onmousemove = mouseMove
window.document.onmousedown = mouseDown
window.document.onmouseup = mouseUp
window.document.ondragstart = mouseStop
}function mouseDown() {
if (drag) {
clickleft = window.event.x - parseInt(dragObj.style.left)
clicktop = window.event.y - parseInt(dragObj.style.top)
dragObj.style.zIndex += 1
move = 1
}
}function mouseStop() {
window.event.returnValue = false
}function mouseMove() {
if (move) {
dragObj.style.left = window.event.x - clickleft
dragObj.style.top = window.event.y - clicktop
}
}function mouseUp() {
move = 0
}
</script> 2.在<body>中插入下列代码 onload="init()" 3.在<body></body>中插入下列代码 <div id="block1" onmouseout="drag=0" onmouseover="dragObj=block1; drag=1;" style="HEIGHT: 90px; LEFT: 200px; POSITION: absolute; TOP: 200px; WIDTH: 90px"><dd><img alt border="0" src="images/howtodo.gif" tppabs="http://howtodo.533.net/images/howtodo.gif"> </dd></div>

GDI+操作不可以用在窗体里当然你可以采用分发组件的形式但那要求客户端安装了框架.>>能在javascript和exe一样执行的非COM/COM+/.NET组件莫数所以我盼望DGI+和web from的技术。javascript是浏览器的脚本语言那么就限制了它只能运行在,浏览器中它虽然可以使用ActiveX组件但GDI+是框架的一部分所以必须要客户端要安装框架.
