C# declare variable into if statement -



C# declare variable into if statement -

i want using c# :

if (i == 0) { button = new button(); } else { textblock = new textblock(); } mainpage.children.add(a);

but error

error 1 name 'a' not exist in current context

any ideas ?

thank in advance !

you need mutual base of operations class both button , textblock derive from, , needs declared outside of if statement if it's accessed after if complete. control maybe?

control a; if (i == 0) { = new button(); } else { = new textblock(); } mainpage.children.add(a);

not knowing specific command toolkit you're using (wpf maybe?) can't advise further. i'd @ signature add clue - what's parameter declared as?

c# variables if-statement

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
