If the code on floor 10 is feasible, then the efficiency should be higher.

The code above doesn't work, but I still sincerely thank everyone.
I want to start with something simple. I have a very small CRC32 program Download it from my ftp://quya.2mydns.com/crc32.com This program runs under code page 437 and doesn't support long file names or directories with spaces, but the following code can get the correct result. The content of file 2.txt is as follows: G:\IBM\oembios.cat The running result is as follows: G:\IBM\oembios.cat D7A77612 First, solve the following problem: how to restore the temporary directory C:\WINXP\TEMP\ to the original directory. Then take it step by step. Thank you everyone. The old-fashioned mind is a bit not working well now. [ Last edited by quya on 2008-7-9 at 09:42 PM ] |

More and more don't know what you're going to do?
G:\IBM\oembios.cat D7A77612 C:\WINXP\TEMP\oembios.cat D7A77612 C:\WINXP\TEMP\oembios.cat D7A77612 C:\WINXP\TEMP\oembios.cat 90BBDCA0 G:\xpdos\WXPOEM\ACER\OEMBIOS.CAT 717B6EF3 C:\WINXP\TEMP\oembios.cat B20C65BF G:\xpdos\WXPOEM\DELL\OEMBIOS.CAT B6F0EEFD G:\xpdos\WXPOEM\HPQ\OEMBIOS.CAT CD4E1902 G:\xpdos\WXPOEM\IBM\OEMBIOS.CAT D7A77612 G:\xpdos\WXPOEM\LENOVO\OEMBIOS.CAT 5237B729 C:\WINXP\TEMP\oembios.cat 700A8481 C:\WINXP\TEMP\oembios.cat 74572CCF C:\WINXP\TEMP\oembios.cat 162C7931 C:\WINXP\TEMP\oembios.cat 74572CCF C:\WINXP\TEMP\oembios.cat D7A77612 Are these the contents of crc.txt? If yes, does that mean the code on floor 7 doesn't work? |

越来越不知道你要干什么了？
G:\IBM\oembios.cat D7A77612 C:\WINXP\TEMP\oembios.cat D7A77612 C:\WINXP\TEMP\oembios.cat D7A77612 C:\WINXP\TEMP\oembios.cat 90BBDCA0 G:\xpdos\WXPOEM\ACE ... I didn't test your code at the unit this afternoon, sorry. Just tried it just now, it's correct and very fast. But can it solve the problem of restoring the original directory in the case of a compressed file? The problem I mentioned on floor 17. Can you explain the meaning of the sentence "for /f "tokens=1* delims= " %%a in (1.txt) do set %%b=%%a"? %%b is the second token, which is "*" in "1*", how can it be assigned a value, I really don't understand. Edit again, I kind of understand. In this way, many variables are generated. The variable name takes the second token, and the assigned value is the first one. I am worried that if my file is very long, will there be too many variable names and errors? Because when I was a child, I knew that I should save variable names and release variables in time. The memory I had back then was extremely small, and I didn't dare to use too many variables. [ Last edited by quya on 2008-7-9 at 10:02 PM ] |

Don't understand
Is there a compressed file in 2.txt? Can crc32.exe decompress it? And decompress it to the C:\WINXP\TEMP\ directory? What was the original directory? |

Did Laotu test my code for version 14? I added judgments and extraction for RAR files in it. You just need to modify it yourself.

The most critical thing is that you extracted it in the current directory, and the current directory may be read-only, so it must be extracted to a temporary directory. Due to the problem of 2, how to get the original directory has become a problem. |

Improve according to your code on floor 17, get the original directory and file name
As for the variable benefit you mentioned, I haven't encountered this problem yet. I made a simple test, and no error phenomenon was found with 100,000 variable names. My physical memory is 128m But if the content of your 1.txt is very long, if you use the previous code for+findstr, you will wait until your hair turns white...

I'm sorry, the 24th floor mentioned 100,000 variable names, but it wasn't fully tested. The actual test showed 40,000.

The code on floors 24 and 25 has a missing % in %~fsi, but it's easy to fix.
The running result on floor 25 is not too ideal: G:\IBM\oembios.cat D7A77612 The running result on floor 24 is nearly perfect: G:\IBM\oembios.cat D7A77612 But I can't figure out why the second-to-last result is like this! I carefully checked the code, and there are no errors. Testing with the following statement is also okay, really frustrating! Everyone has worked hard!!! Thanks a million!!

If you don't generate the temporary crc.txt:

After carefully checking, there is still an issue.
F:\e\Backup\Tools\OEM 5文件\Acer\OEMBIOS.CA_ B20C65BF Here, all are the same. |
