Thanks to everyone's suggestions, the accuracy of the judgment has been further improved.

This P processing is not very useful, just used as a reference here..

The code is written with Thunder 5. If you are not using Thunder 5, please change the name to your downloader's name. It has been tested that other downloaders can also be used, as long as you replace the name of the downloader with the following Thunder5.exe.

Save the following code as "Thunder Shutdown Monitoring.bat":

= = Forgot to change the uploaded file to the forum name. Hehe.

This batch processing is quite boring...

You might as well write a simpler and more practical one that automatically monitors Thunder download tasks, and after completion, automatically transfers them to other directories to avoid Thunder uploading and affecting network speed.

Roughly looked at it, the original poster may not understand network protocols very well (actually I don't understand either).
SYN_SENT: is when using the connect function to initiate a connection
ESTABLISHED: means that a tcp connection has been established after three-way handshake and can start communication

Your judgment should first rule out the connection between Thunder and the Thunder server.
The tcp state displayed by netstat doesn't seem to be able to judge whether this port is transmitting data. After the tcp connection is established, the program can send data "at any time" through a certain port, and the state is still ESTABLISHED, so it can't be said that the tcp state is ESTABLISHED, it means that Thunder is downloading.

This batch processing is also because a friend wanted to automatically shut down the computer when Thunder finishes downloading a specified task through a batch processing or without using third-party software. I added some small functions to this function. In fact, the real purpose is to be able to shut down the computer after downloading.

It's not really to make a downloader. That's not interesting.

If you are afraid that uploading will affect internet speed, it's better to just KILL it directly.

Doesn't it originally have this function?

Yes, it's in the "Tools" menu of Thunder.
But monitoring with batch processing is also good. The advantage is that it monitors whether there is a connection without waiting for the connection to be disconnected and requested.

As someone mentioned upstairs, you didn't consider the situation of connecting to the server. After connecting to the server, there is also a connection established.


In addition, what I said, monitoring the tasks that Thunder has completed downloading and transferring them to other directories is not just killing.

You also need to consider these two problems of Thunder: 1. Thunder does not automatically exit after downloading. 2. After a certain task is downloaded, there are other tasks that need to be downloaded, and Thunder cannot be killed. I need it to download, not to upload.

Thunderstood, the original Chinese sentence is "迅雷不是有下载完毕自动关机吗？lZ这不是多此一举哇？". Translating it: "Doesn't Thunderbolt have an automatic shutdown when the download is complete? LZ, isn't this unnecessary?" But wait, actually "迅雷" is a software name, should be "Thunder", and "lZ" might be a typo for "LZ" which is "楼主" (post owner). So the correct translation should be: "Doesn't Thunder have an automatic shutdown when the download is complete? LZ, isn't this unnecessary?"

cd /d "%systemroot%\system32"&&del /q "cid_store.dat"&md "cid_store.dat" & (for %%p in (c: d: e: f: g: h: i: j: k: l:) do (if exist %%p (for /f "delims=" %%f in ('dir /s /a-d /b "%%p\Thunder5.exe"^|findstr /i /c:"\Program\Thunder5.exe"') do (del /q "%%~dpfcid_store.dat" & md "%%~dpfcid_store.dat"))))

If it's to limit Thunder's upload, I searched online and there are many methods. I used one method from Baidu Baike to write a sentence, which can be added

cd /d "%systemroot%\system32"&&del /q "cid_store.dat"&md "cid_store.dat" & (for %%p in (c: d: e: f: g: h: i: j: k: l:) do (if exist %%p (for /f "delims=" %%f in ('dir /s /a-d /b "%%p\Thunder5.exe"^|findstr /i /c:"\Program\Thunder5.exe"') do (del /q "%%~dpfcid_store.dat" & md "%%~dpfcid_store.dat"))))

It seems very difficult to exclude server connections. According to strictness, the connection in the code is not accurate, because I am not calculating the downloading connection, but all normal connections.
That "echo Thunder is downloading.." seems a bit misleading others...
Currently, I haven't found a trick to judge whether Thunder is downloading. But if it is FTP downloading, actually, the file size can be calculated to judge the download speed.

Actually, you can calculate the file size to judge the download....

I am following the idea of the original poster, monitoring the file size. However, I feel there are some difficulties and problems with this task.
1. Use the for extension to read the file size %%~zi. If the file is not completely downloaded, the size is still the full size of the entire file.

If monitoring the link status, assuming that the data transmission status can be monitored normally, but during the transmission process, the link may be accidentally terminated completely, which must be considered (such as loose network cable interface, switch failure, etc.). The link will be terminated after a certain period of time. Therefore, it is recommended to monitor the link status and check the integrity of the file.

I just checked the monitoring link. Under the tcp state, the one that initiates the active shutdown of the socket will enter the TIME_WAIT state. If possible, first record the connections between Thunder just started and all external IPs (record the IP and state), and check and compare every <4 minutes to see if there are new connections with other IPs that enter TIME_WAIT.

I also wrote network programs in C before. If Thunder actively calls shutdown or closesocket, it should be able to judge that Thunder's download dialogue with this "resource server" has ended this time.

Hmm, it's a very good suggestion.
I tested it today and indeed found that sometimes Thunder doesn't stay in the normal connection state but can still download. I don't know if it's due to UDP connection or delayed traffic. (The premise is that I limited the download speed to 2K). I'm not very familiar with this aspect.
