I've included options to limit the file types to upload as well as limiting individual file size and total file size and can all be set using the server control.

为了限制文件上传的类型，单个文件的大小，所有文件的大小我改善了服务器控件的选项。

For instance, Firefox USES a button for a trigger, a slider for a range, and a standard file open dialog box for an upload control.

比如，Firefox使用按钮表示trigger，使用滑动条表示range，使用标准文件打开对话框表示upload控件。
