storage - Storing and recalling variable number of text strings in LaTeX -

-

I am currently writing an API document in latex. I have a tabular environment with a list of error codes and details such as: 

  \ begin {tabular} {| C | L |} \ hline \ textbf {code} & amp; \ Textbf {Details} \\ \ hline 1 & amp; (Details of error 1) \\ \ hline 2 & amp; (Details of Error 2) \\ \ hline \ end {tabular}

Later on in different documents in the document, I refer to an error code and its details at the same time, such as:

Possible error status: \ start {itemize} \ item 1 --- (error description 1) \ end {itemize}

I I want to automate the process so I do not have to type the details again every time I try to use a counter, labels, and \ savebox command , But it is very complex:

\ newcounter {error}% in tabular environment: \ newsavebox {\ ErrorOne} \ savebox {\ ErrorOne} {(description of 1 error)} \ Refstepcounter {error} \ label {errorOn} \ Arabic {error} & amp; \ Usebox {\ ErrorOne} \\ \ hline

and later, to reference the error, 

  \ {errorOne} --- \ Objectbox {\ ErrorOne}

I have an object specifically for using ErrorOne for labels, but for \ Saveboxes \ ErrorOne (with leading backslash). I do not really want a name like error on, because I might have to change the order at some point. All I have to do should be able to define some command: 

  \ newerror {errorlabel} {description}% defines error (no one does not output) \ errorcode {Errorlabel}% outputs the error code \ errordesc {errorlabel}% error description

and then 

  \ newerror {ArgumentError} {lots All logic} \ Newerror {DatabaseError} {could not connect to the database}% Tabular inside the environment: \ errorcode {ArgumentError} & amp; \ Errordesc {ArgumentError} \\ \ hline \ errorcode {DatabaseError} & amp; \ Errordesc {DatabaseError} \\ \ hline% at: \ errorcode {DatabaseError} --- \ errordesc {DatabaseError}

Error code (1, 2, 3, .... )

Any thoughts?

does the following for me 

  \ catcode` \ @ 11 = Newcomer {error} \ def \ newerror # 1 # 2 {\ refstepcounter {error}% \ expandafter \ xdef \ csname errno @ # 1 \ endcsname {\ arabic {error}}% \ expandafter \ xdef \ csname errds @ # 1 \ endcsname {# 2}%} \ def \ errorcode # 1 {\ expandafter \ printerrinfo \ csname errno @ # 1 \ endcsname} \ Def \ errordesc # 1 {\ expandafter \ printerrinfo \ csname errds @ # 1 \ endcsname} \ Def \ printerrinfo # 1 {\ ifx # 1 \ relax \ errmessage {error code is invalid}% \ and \ extended # 1 \ fi} \ Catcode \ \ @ 12 = newerror {ArgumentError} {lots of arguments} \ new terror {DatabaseError} {Could not connect to database} \ Errorcode {DatabaseError} --- \ erordesc {DatabaseError}

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
