This is the code that the appPosterScreen uses from the video player example to pass the video information from the Poster screen to the spring board

'**********************************************************
'** When a poster on the home screen is selected, we call
'** this function passing an roAssociativeArray with the 
'** ContentMetaData for the selected show.  This data should 
'** be sufficient for the springboard to display
'**********************************************************
Function displayShowDetailScreen(category as Object, showIndex as Integer) As Integer

    if validateParam(category, "roAssociativeArray", "displayShowDetailScreen") = false return -1

    shows = getShowsForCategoryItem(category, m.curCategory)
    screen = preShowDetailScreen(category.Title, category.kids[m.curCategory].Title)
    showIndex = showDetailScreen(screen, shows, showIndex)

    return showIndex
End Function

'***************************************************************

I need somehow for the values here :

else if msg.isListItemSelected() then

            m.curShow = msg.GetIndex()
            m.curShow = displayShowDetailSearchScreen(m.showSearchList, m.curShow)
            screen.SetFocusedListItem(m.curShow)

to populate this below:

if validateParam(m.showSearchList, "roAssociativeArray", "displayShowDetailSearchScreen") = false return -1

shows = getShowsForCategorySearchItem(m.showSearchList, "0")
screen = preShowDetailScreen("0", "0")
showIndex = showDetailScreen(screen, shows, showIndex)

I tried m.showSearchList because "category" didnt seem to work

and i tried hardcoding the other parts with "0" because I couldnt get variables to replace these:

.Title

and once again my full code is here:

Sub SearchResultsMain()

    'initialize theme attributes like titles, logos and overhang color
    initTheme()

    'prepare the screen for display and get ready to begin
    screen=preShowPosterSearchScreen("", "")
    if screen=invalid then
        print "unexpected error in preShowPosterSearchScreen"
        return
    end if

    'set to go, time to get started
    showPosterSearchScreen(screen)

End Sub
 
'******************************************************
Function preShowPosterSearchScreen(breadA=invalid, breadB=invalid) As Object

    port=CreateObject("roMessagePort")
    screen = CreateObject("roPosterScreen")
    screen.SetMessagePort(port)
    if breadA<>invalid and breadB<>invalid then
        screen.SetBreadcrumbText(breadA, breadB)
    end if

    screen.SetListStyle("flat-category")
    return screen

End Function

'******************************************************
Function showPosterSearchScreen(screen As Object) As Integer
   
   categorySearchList = getCategorySearchList()
   screen.SetListNames(categorySearchList)
   screen.SetContentList(getShowsForCategorySearchItem(categorySearchList[0]))

   m.showSearchList = getShowsForCategorySearchItem(categorySearchList[0])
   screen.SetContentList(m.showSearchList)

   screen.Show()

    while true
        msg = wait(0, screen.GetMessagePort())
        if type(msg) = "roPosterScreenEvent" then
            if msg.isListFocused() then

 m.curCategory = msg.GetIndex()
 
 	screen.SetFocusedListItem(m.curShow)
 	screen.SetContentList(getShowsForCategorySearchItem(m.showSearchList, m.curCategory))

else if msg.isListItemFocused() then
		print"list item focused | current show = "; msg.GetIndex()

                
else if msg.isListItemSelected() then

            m.curShow = msg.GetIndex()
            m.curShow = displayShowDetailSearchScreen(m.showSearchList, m.curShow)
            screen.SetFocusedListItem(m.curShow)

     else if msg.isScreenClosed() then
                return -1

This actually is just a rework of the simplePoster.brs in the simple poster example. we have added the ability to use xml to populate the actual poster. and now i am trying to pass that info onto the springboard screen, which i want to use the springboard already in use if possible.

Does that help? I think if i can figure out how to get those variables into what i shown above i should be able to get that over to the already built spring Board

if you have a better idea on how to do this, please pass it on... i have spent days on this and is killing me....

I think it's going to be a lot easier, if you just leave everything else the way it is, and just modify what "getShowsForCategoryItem" returns. As long as it returns your search items in the same format as it's expecting, it should just work. Don't get caught up in renaming category to search and vice versa, because I think that's what's mainly tripping you up. So, I would recommend starting afresh with the SimplePoster.brs, and just change the "getShowsForCategoryItem" function.

endless i almost got this but this "category" is using a "roAssociativeArray"

I tried printing all sorts of ways to get the category's info so i can hard code it in my show feed

category kids <ROT:roAssociativeArray>
<ROT:roAssociativeArray>
<ROT:roAssociativeArray>
<ROT:roAssociativeArray>
<ROT:roAssociativeArray>

and no matter what i do as far as printing goes i cant figure out all that makes this variable so i can recreate it and hard code it here:

conn = InitShowFeedConnection(category.kids[item])

if xml looks like this:

<categories>

<category title="world war two" description="" sd_img="http://xxxxxx.com/roku/images/wwII.jpg" hd_img="http://xxxxxx.com/roku/images/wwII.jpg">

		<categoryLeaf title="search" description="" feed="http://xxxxxx.com/roku/feeds/search.php"/>
	</category>

and i need to get to the "feed" what could i use to replace this ")"

i tried using InitShowFeedConnection(movies) but that didnt work either

There is a PrintAA() utility function in the example code that I find very useful. It takes a roAssociativeArray as an argument and prints its contents to the console.

Thanks Chris,

But I added that all i get is a error saying

Wrong number of function parameters.

167:     PrintAA()

i am guessing there is more than just typing that in now.... and if so, what is the complete and correct way of doing it?

you said example code, which example though?

[renojim]

You missed where Chris said, "It takes a roAssociativeArray as an argument". So you need PrintAA(category).

thanks RenoJim....

the problem is that this can still be confusing and i take what is given to me literally at times, I am still not getting this to work even after ready that array

I am just trying to reproduce it so i can do a search in the video player example, i can get it right to the point of showing the feed but not able to view it once clicked. basically i cant click the the video in the poster and send it to the springboard that the video player already uses.

I think my only chance is to bloat the code more and just create another AppDetailscreen. i was trying to avoid that by changing some code around and using existing code, but i have found that these examples do not play well with each other!at least with what i can do with brightscript.

thanks for all your help guys
