lately I needed a watermark textbox, the first thing that popped in to my head was OnLeave and OnEnter events of textbox, but first I googled it and I got two links first was the one in CodeProject which used the System.Drawing namespace and the other one was here using the SendMessage() over here http://vidmar.net/weblog/archive/2008/11/05/watermarked-textbox-in-windows-forms-on-.net.aspx.
最近我需要一个水印文本框，第一个出现在我脑海中的是文本框的 OnLeave 和 OnEnter 事件，但首先我用谷歌搜索它，我首先得到两个链接是 CodeProject 中使用 System.Drawing 命名空间的一个和另一个一个在这里使用 SendMessage() 在这里http://vidmar.net/weblog/archive/2008/11/05/watermarked-textbox-in-windows-forms-on-.net.aspx。
I beleive the SendMessage one is much easier and it also has no flickering in it. though I used it.
我相信 SendMessage 更容易，而且它也没有闪烁。虽然我用过。
I hope it will be helpful for you.
