mono - Passing Data between Activities of TabHost Control -


i have tabhost add tab's dynamically. problem updating data in 1 tab tab values selected.

for ex: have 2 tabs named 'search & filter' , intents added in tabhost activity page. when select values spinners 'site & equipment' filter tab want update search tab list view specified selection filter tab.

i have attached sample code. kindly verify , suggest me on same.

tabhost activity:

public class tabsearch : tabactivity  {     protected override void oncreate(bundle bundle)     {             base.oncreate(bundle);             setcontentview(resource.layout.search_wotab);              tabhost.tabspec tspec;             intent intent;             intent = new intent(this, typeof(wosearch));             intent.addflags(activityflags.newtask);             tspec = tabhost.newtabspec("search");             tspec.setindicator("search", resources.getdrawable(resource.drawable.search));             tspec.setcontent(intent);             tabhost.addtab(tspec);              intent = new intent(this, typeof(wofilter));             intent.addflags(activityflags.newtask);             tspec = tabhost.newtabspec("filter");             tspec.setindicator("filter", resources.getdrawable(resource.drawable.filter));             tspec.setcontent(intent);             tabhost.addtab(tspec);              tabhost.tabchanged += (sender, e) =>             {                 spinner workorder = findviewbyid<spinner>(resource.id.sp_site);                 object data;                 //here showing null spinner control                 if (workorder!=null)                     data = workorder.selecteditem;                 toast.maketext(this, tabhost.currenttab.tostring(), toastlength.short).show();             };     } }

what :

  1. in wofilter tab :

    • when select element update app_wide var (static, sharedpref, database, like) let's "wo_filter_value". way, wofilter activity don't have know wosearch activity

  2. in wosearch tab :

    • only initialisation code in "oncreate" method (what's need 1 once)
    • do list display part in "onresume" method, reading updated "wo_filter_value" , filtering accordingly.

as 1 tab displayed @ same time, activity have go through "onresume" function before redisplaying list after have changed filter on other tab.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
