@Echo Off
:send
Set /p num=Enter the other party's QQ number:
If /I "%num%"=="n" Exit
start tencent://Message/?Uin=%num%
cls
Goto send
This code can start a temporary chat with any QQ user.
What I want to ask is: in the command start tencent://Message/?Uin=%num%, how was the address tencent://Message/?Uin=%num% obtained? For example, if I want to open another function of some program, how can I get a similar address?

Set /p num=Enter the other party's QQ number: //declare the variable num
If /I "%num%"=="n" Exit //if the return is N then exit
start tencent://Message/?Uin=%num% //%num% is just the QQ number you entered, it's that simple
Or you can change it a bit,,,
@echo off
:send
Set /p num=Enter the file and path you want to open (enter n to exit): //enter the full path of the program you want to open! For example E:\qq2007\qq.exe
If /I "%num%"=="n" Exit
start %num%
cls
goto send

Thanks for your reply.
That's not what I mean.
With start tencent://Message/?Uin=, no matter where your QQ is installed, it can open a temporary chat for you. What I want to ask is: if I want to call a certain function of another program, how can I get a similar address?

What you mean is, why can start tencent://Message/?Uin= open a temporary chat no matter where your QQ is installed,
right? But I don't know either, I'll wait for the answer with you.

I want to know too

start, when no directory is specified, will search according to the PATH in the environment variables and execute the first matching program. If it can't find it in PATH, it will report an error!


I don't really understand the OP saying QQ will definitely run!
