对于 Custom HTML 模块,其添加方法和 Windows Media Player 模块类似,只是 URL 里要添加的是“&powertoy=sandbox”。
Custom HTML模块界面如下图所示。在 HTML 框内写入 HTML 代码,不过代码长度有限制,不能超过 2048 个字符。“Modulus Name”(模块名称)可有可无,同样“Show Border”(显示边框)也可选可不选,如果不想显示此模块边框和标题栏就不要打上勾。最后,点击“Save”(保存)就大功告成了。
如果你有想置顶的文字、图片、计数器、以及播放背景音乐的代码,放到这个模块里就好了,真正的置顶!而且不用每次重新发布,修改起来也很方便。
在我的空间主页中,用来显示“老虎”图片和“卧虎藏龙”标题的就是 Custom HTML 模块。 大家可以看看效果,推荐使用!要在 Custom HTML 模块中添加图片、计数器,请分别参考教程(七)的贴图语句和教程(十)的添加计数器方法。如果想添加两个 Custom HMTL 模块,请看教程(三十一)!
第三个 PowerToy 是 Tweak UI 模块,用来调节 Live Spaces 的背景颜色、背景图片、字体颜色、模块样式等。在 URL 中需要添加的代码是“&powertoy=tweakomatic”。
其界面如下:
教程(三)中有个网络常用颜色列表,可以用来选择自己喜欢的颜色,并得到相应的颜色代码,需要的朋友可以去看看。对于我的 MSN Space 来说,目前觉得有用的选项是“Background Colors”。可以统一内部(Inner)和外部(Outer)的背景颜色,不会在右边留下浅色的空白,使 Space 网页显得浑然一体。其他选项写的比较直接,大家稍微实验一下就能明白,比如:Module Borders 中的 Style 可以设置模块边框为 dotted(点)、dashed(虚线)、solid(实线)、double(双线)等,我就不做过多的介绍了。

补充说明:上述三个 PowerToy 模块,相互之间并不无关联,可以同时拥有。至于能否添加多个 PowerToy 模块,比如:添加两个 Custom HTML 模块,答案是肯定的,请看教程(三十一)!而且一定要仔细看教程,包括最后的说明部分,不然你在添加其他模块的时候很可能会遇到其他问题。

When trying to do a Oracle database dump or export, be it full entire database export or a particular user or table export, the following message may appears right after status of exporting a table.
EXP-00091: Exporting questionable statistics.
The cause for this error is because statistics may not be useable although Export was able to export statistics. The statistics are questionable because one or more of the following happened during export:
The resolution is to export non-questionable statistics, change the client character set or NCHARSET to match the server, export with no query clause, or export complete tables.
Most commonly, the EXP-00091 happens when the character set of client where Exp is running is different from character set of Oracle database server.
To solve this issue, try setting the NLS_LANG environment variable at the OS level, prior to the export session, to match your database character set. Syntax as follow, change the character set to your database’s character set.
export NLS_LANG=WE8ISO8859P1
For easier way of resolution, export with option “STATISTICS=NONE”. Also, if you’re using Oracle 10g, use Oracle Date Pump’s expdp and impdp instead of instead of exp and imp to export and import the data.
It’s pretty safe to say that if EXP-00091 is the only error message, the export’s row data is without any problems. If desired, import parameters can be supplied so that only non-questionable statistics will be imported, and all questionable statistics will be recalculated.
At the beginning of Export, the charset of the database will be shown. Else, you will need to use “show parameter nls” in SQL*Plus to check what charset the Oracle database is using.
