[Tex/LaTex] ! LaTeX Error: Command \removefromreset already defined

errorsmacros

There are ready files for preparing Latex document. I used .cls template file and it has below code:

\newcommand{\@removefromreset}[2]{{%
  \expandafter\let\csname c@#1\endcsname\@removefromreset
  \def\@elt##1{%
    \expandafter\ifx\csname c@##1\endcsname\@removefromreset
    \else
      \noexpand\@elt{##1}%
    \fi}%
  \expandafter\xdef\csname cl@#2\endcsname{%
    \csname cl@#2\endcsname}}}

However, when I run my .tex file, an error occurs "! LaTeX Error: Command \removefromreset already defined"

Could you please help?

Since the LaTeX release from 2018/04/01 the \@removefromreset command is part of the LaTeX kernel.

The code by D. Carlisle was in remreset.sty (its author is D. Carlisle) and has been incorporated into the kernel. With any newer LaTeX version since 2018/04/01 there must be a conflict with a copied over code from remreset.sty. remreset is now declared obsolete.

The only way to remove the error is to remove the \newcommand{\@removefromreset}... from the class file.

The loading of remreset is also discouraged: (From remreset.sty):

%... header omitted here

% \LoadClass{book}
% \@removefromreset{footnote}{chapter}

% 2018: package obsoleted as the command is defined in the LaTeX format.

\@ifundefined{@removefromreset}{%
\def\@removefromreset#1#2{{%
  \expandafter\let\csname c@#1\endcsname\@removefromreset
  \def\@elt##1{%
    \expandafter\ifx\csname c@##1\endcsname\@removefromreset
    \else
      \noexpand\@elt{##1}%
    \fi}%
  \expandafter\xdef\csname cl@#2\endcsname{%
    \csname cl@#2\endcsname}}}%
}{%
\PackageWarningNoLine{remreset}
    {The remreset package is obsolete:\MessageBreak
     \noexpand\@removefomresset is defined}%
}

[Tex/LaTex] LaTeX Error: Command \openbox already defined

The code tries to define the command \openbox, which is already defined. This leads to that error message. Check your file C:\Program Files\MiKTeX 2.9\tex\latex\mytheorem\demonstration.sty for this.

Very probably you already loaded a package, which defines \openbox. For example, amsthm and ntheorem both define it, and both in the same way:

\newcommand{\openbox}{\leavevmode
  \hbox to.77778em{%
  \hfil\vrule
  \vbox to.675em{\hrule width.6em\vfil\hrule}%
  \vrule\hfil}}

You can see the commands

\vrule\hfil}}

from your error message.

Remove the package(s) from your preamble, which you don't need. And if you need it and you would like to keep it, don't define the same command again or use \renewcommand instead of \newcommand if it's your intention to change a macro definition.

[Tex/LaTex] LaTeX Error: Command \c@T already defined

What's apparently happening is the following: as @Ulrike remarks, your \newenvironment lacks its two mandatory arguments. It will instead pick up \newcounter and definition, since that is what follows.

What this does is that when you call \begin{definition}, you inadvertently call \newcounter, so

\begin{definition} The thing

turns into, with some technicalities omitted,

\newcounter The thing

i.e.

\newcounter{T}he thing

and that's where your counters come from and that's why you get an error: you probably have to definitions that start with "T"!

(To backtrack and solve your problem: I think you really mean to look at the amsthm package and its \newtheorem command?)
