checkbox - How to enable button according to the number of checked checkboxes powerbuilder? -


i have datawindow checkboxes , button 'ok'. button disabled until @ least 1 of checkboxes checked. problem if have more 1 checkbox checked , want uncheck 1 button disables. wrote code in itemchanged event:

int li_ind long    ll_row  choose case dwo.name     case "ind"         row = 1 this.rowcount()             if  data ='1'                       li_ind++             end if         next          if li_ind <> 0             parent.cb_ok.enabled = true         else             parent.cb_ok.enabled = false         end if  end choose

what doing wrong?

thanks!

you put hidden computed field in detail band of datawindow named cf_ind_count.

define cf_ind_count

sum( if( ind = '1', 1, 0 ) )

replace script with

long ll_count long ll_rows boolean lb_enable = false  ll_rows = this.rowcount()  if ll_rows < 1     lb_enable = false else     ll_count = long( this.object.cf_ind_count[1] )     if ll_count > 0         lb_enable = true     else         lb_enable = false     end if end if  parent.cb_ok.enable = lb_enable

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
