『楼 主』:
实现显示器的尺寸大小的批处理
各位大侠好，小弟想提一个问题。
怎样用批处理判断显示器的尺寸大小呢？然后将得到的判断节果写入一个文本文档中。然后再将此文本文档命名为显示器尺寸的名字，如：是17寸的，则命名为17.txt
小弟很菜鸟，不过很热爱批处理，后面的重命名我还是会的。

尺寸大小?这个要看显示器驱动了吧,不是显卡驱动.我看Xorg实现了,但是移植到DOS可能不现实

Sorry I can't type Chinese currently...
First of all, you have to understand when we're talking about the SIZE of a monitor, we're ACTUALLY talking about the MAX viewable image size of a monitor, or "diameter".
I have to say, due to no direct info about diameter is provided, it's not easy to get the diameter of your monitor without the help of a 3rd party tool.
(BTW, the resolution is easy to get, however it can't be used to calculate the diameter of your monitor.)
Recently in a computer, all info about the monitor come from EDID(a VESA defined data structure, for detail: http://en.wikipedia.org/wiki/EDID). EDID BYTE 21 and BYTE 22 define the horizontal/vertical MAX viewable image size, separately.
You could get EDID via I2C, perform a calculation with EDID BYTE 21 and BYTE 22, and a conversion from centimeter to inch, the result you get is very close to the desired monitor-size.
Another approach is much easier: by the name of the monitor, like "DELL E228WFP" indicating 22-inch. However even if you could get the name from EDID or Windows Registry, this isn't a reliable approach for 2 reasons.
1st reason: NOT all monitor names reflect the sizes, like "EPI EnVision EN-775e", what the hell is this size?
2nd reason: It's NOT easy to parse the name. Every naming convention differs among monitor vendors.
Best way:
You could use this tool: http://www.nirsoft.net/utils/dumpedid.zip (for Windows ONLY) to get EDID and diameter.
usage: DumpEDID.exe > YourFile.txt
or: DumpEDID.exe \\remote01 > YourFile.txt
Here's a typical output by DumpEDID.exe:

Sometimes we'll get diameters like 18.9 Inch or 17.1 Inch. It's not a big problem, I believe you know the right thing to do. ^ _ ^.
