vb.net - TabControl.SelectedIndex being changed, but SelectedIndexChanged even not firing -

-

all,

i have tabcontrol in application started behaving strangely. background...

this program converted vb6 vb .net 2008, , used refer forms using class names. in other words, might have form class called frmfoo. in code program might see:

frmfoo.show()

or

frmfoo.userdefinedproperty = true

during recent changes, created variables represent instances of forms these:

public myform frmfoo  myform = new frmfoo myform.show()

in doing so, removed code form's load event handler , put in form's constructor.

when form loads, or when document loaded , should influence tabcontrol's selected index, following not fire selectedindexchanged event.

myform.tbsform.selectedindex = valuereadfromfile

...or...

myform.tbsform.tabs(valuereadfromfile).select

sorry wordy, there's more. if open form , @ tabcontrol verify it's been set properly, works it's supposed to. misbehaving tabcontrol contained within tabcontrol, have click parent tabcontrol see it. if can see it, , run test, test works. if can't see it, , run test, first test run not fire event. ...paging dr. heisenberg...

it's if control has initialized first changing value or making visible onscreen...i'm totally lost on one. it's unusual behavior i've ever seen. , worked before began using variables represent forms , placed load event code form constructors.

can help, or @ least put me out of misery? sh

-------------------------------------------------------------- edit #2
performed test after having attempted eliminate of variability in behavior. wanted confirm previously-stated behavior.

i opened program , read file. file contained value should have triggered event handler. without making control visible, can change selectedindex property of tab control without event firing.

i closed program down again, , reopened it. time, selected parent tab allowed child tab (the 1 event i'm concerned with) become visible. selected different tab in parent control, meaning child control no longer visible. when opened same file before, fired event.

i'm tempted implement flag confirms control has been repainted or whether parent tab has been displayed. may have fire event in code if flag isn't set.

i want reiterate worked when program referred forms class names , of arrangement of controls on forms done in load event. program creates variables , arrangement of controls done in form's constructor. i'm sure has problem i'm having, can't understand how. wisdom share?

myform.tbsform.selectedindexchanged = valuereadfromfile

doesn't make lot of sense. tha trying assign handler selectedindexchanged event? or valuereadfromfile name of tab?

what you're saying have 2 tab controls, say, , b. tab control b contained within tab of a, , unless has tab page selected contains tab control b, selectedindexchanged event of b not fire if change tab programatically?

in different ways have tried select tab within child tab control, , when code being executed?

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

-
i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
