liuzhaoyzz,

Welcome to the AutoIt forums.

What have you tried that has not worked?

Take a look at WMI classes - like Win32_LogicalDisk or Win32_DiskDrive or Win32_DiskPartition.  Google AutoIt WMI to have examples of the how-to...

WMI is not equal to WMIC.  I thought he meant without external program.

If WMI is OK, then please check SciptOmatic on the download section of this forum. It generates the AutoIt code to access WMI for you.

I don't want to realize by  wmic,for wmic or  diskpart maybe  not available in PE .And  I don't want to read  the  registry  also .

WMI has too much restrict. 

Win32_DiskPartition class,can see BootPartition,it seems it differs from active partition ?I don't know.

I prefer  to read MBR to  get  it .Or use windows API or  au3 dllcall directly .

Which are ?

[liuzhaoyzz]

In PE or some reduced windows,WMI Component packages maybe reduced.

I want to use more Infrastructure function.

BuildPartitionTable (link in my sig in spoiler) may be helpful (not sure about your requirements).

[liuzhaoyzz]

I didn't find BuildPartitionTable,what does it mean link in my sig in spoiler?

Could you post a hyperlink?

My requirements is like below,dsptw.rar.

dsptw has some bugs,the author has not updated it for many years.

Please write your post with the default font; you don't need to write with this font.

By the way, @RTFC was meaning to look at this.

The default font is too small,it's hard to see.So I select H2 or H3.

Thank you.

Please don't, simply enlarge your browser zoom level in stead of "shouting at us".
