android - How do I use instantiateItem correctly with a mixture of view and layouts objects? -

-

I am trying to get this code working: 

  @Override public object instantiateItem (See group collection, condition of int) {see v = faucet; If (0 == position) {string data = " gt; body> yes there  gt; & lt; html & gt;"; WebView wv = (webview) Find VVBIID (RaidView); Wv.loadData (data, "text / html", tap); V = wv; } And {layout influer vi = (layout inflator) CTT system system (references LAOUT_INFLATER_SERVICE); V = vi.inflate (R.Letter.Editor, empty); } Collection.addView (V, 0); Return vi; }   
 I am copying this article here to create a horizontal swiping view by default:  
 When I use this code, Crash Got Any Suggest I'm not collecting correctly by trying to insert a layout in ViewGroup?

 You will need an artist to solve your problem. Change:  
  Archive. AddView (V, 0);   
 In:  
  ((Vypegger) collection) .addView (v, 0);

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel).

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
