c# - Custom Control in VS Designer: Avoid serialization of Collection properties -


i made new winforms control

public class jwgraph     inherits control

this control has bindinglists(of foo) in them. in order avoid other visual studio errors in regards serialization (error messages) added serializable attribute foo , other tags bindinglist(of foo).

example:

foo declaration

<serializable> _ public class freemarker

bindinglist(of foo) declaration:

<system.componentmodel.browsable(false)> <editorbrowsable(editorbrowsablestate.never)> <system.componentmodel.designerserializationvisibility(system.componentmodel.designerserializationvisibility.hidden)>     public withevents freemarkers bindinglist(of freemarker)

when use control, visual studio adds base64 data ressources form's resx file , lines like

me.jwgraph1.freemarkers = ctype(resources.getobject("jwgraph1.freemarkers"), system.componentmodel.bindinglist(of jwtoollib.jwgraph.freemarker))

to designer. problem is, can't change in control's code after point (or changing assembly) in way, because deserialization fail , have go great lengths running again @ all.

many controls use collections. can't seem find difference between implementations (i tried looking @ basic controls in reflector) , mine, , yet collections not show in designer in such way.

so how can prevent collections being generated binary ressources @ design time? initialized in control's constructor.

my code in vb.net answers in c# welcome.

like always, gray hair 3 hours straight, decide ask, promptly find solution:

as described here http://msdn.microsoft.com/en-us/library/53b8022e%28v=vs.100%29.aspx can add shouldserialize[...] functions code prevent specific fields being serialized. guess designer evaluates these functions , decides do.

to keep example above:

in addition 

<system.componentmodel.browsable(false)> <editorbrowsable(editorbrowsablestate.never)> <system.componentmodel.designerserializationvisibility(system.componentmodel.designerserializationvisibility.hidden)> public withevents freemarkers bindinglist(of freemarker)

add 2 functions class:

public function shouldserializefreemarkers() boolean     return false end function public sub resetfreemarkers()     series = nothing end sub

and lo , behold: no more design time serialization.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
