When I tried to open Device Manager or the Computer Management window I received an error message MMC Cannot open the file?
error language description MMC cannot open C:WINDOWSsystem32devmgmt. Moscow time This may be because the file does not exist, is not always an MMC, or was programmed with a later version of the MMC. It could also be because the buyers don’t have enough legal permissions to access the file.

Optional thank you note:
I have a servlet that typically receives a small amount of XML data. The code below works, but if I get invalid XML data and an exception is thrown, I still want to allow them to read and get the effect tag data.

Recently, some projects need to receive POST XML data packets. In the platform servlet, call request. and getinputstream() to ensure that no data is to be read. .

The component must use inputStream. No problem. Undoubtedly, it is impossible that it does not work here. Then flashed or
