c# - Why would this code be placed in a *.Designer.cs file? -

-

in project i'm maintaining, original developer put code @ top of main form's designer.cs file:

private void memberlistbox_load() {     datatable dtmembers = null;     sqlserver sqldal = null;      sqldal = new sqlserver(properties.settings.default.bidataconnection);     sqldal.commandtimeout = 120;     dataset dsmember = sqldal.runsqldataset("select poisontoe platypusdata..members abs(activeflg)=1 order poisontoe", "members");     dtmembers = dsmember.tables[0];      memberlistbox.datasource = dtmembers;     memberlistbox.displaymember = "poisontoe";      foreach (datarow unitdprow in dtmembers.rows)     {         string x = unitdprow[0].tostring();         memberlistbox.setitemchecked(memberlistbox.findstring(x), true);     } }

wouldn't mainform.cs more usual location such code? purpose of having in mainform.designer.cs? should move out mainform.cs?

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
