Store Search History

I am looking for suggestions on how best to store the history for the search screen. It is populated from an roArray, but when I try to write the roArray to the registry it complains of a type mismatch. I would like to hear how others have done this. I would prefer to keep the search term on the Roku rather than sending it to the server.

I appreciate hearing how you have done this.

Thanks.

Re: Store Search History

The Roku has a global search history that will automatically persist when you add terms to it. See the roSearchHistory component in the SDK.

Here is a simple example I put together awhile back that might help: viewtopic.php?f=34&t=32518&p=202516#p202518

Re: Store Search History

I looked at that, but I don't want to use the global search history in my app. I get annoyed enough by the apps that already use it.

You can only write strings to the registry. One solution would be to use roXMLElement to build a chunk of XML representing the contents of your search history array and store that in the registry.

Re: Store Search History

Here is some code that I have used, while out of context, it might provide some clues to help you. At the bottom are some of my registry management functions.

*********************************************************************
Write the current search term to the registry: (note, this is an excerpt and is based on previous search terms having already been loaded into histlist from the registry. It checks if the search term is already in the registry and if not then it adds it to the list and removes the oldest term from the list)

 
'code excerpt from a search screen
'm.tquerystring contains is the current search term.
'histlist contains list of search terms loaded from the registry
histlist=m.historylist 'this line should go at the very top of the search function

flag=0

for i=0 to histlist.count()-1
if m.tquerystring=histlist[i]
flag=1
end if
next i
if flag <> 1 then
histlist.unshift(m.tquerystring)
if histlist.count() > 9
histlist.pop()
end if
end if
searchscr.setsearchterms(histlist)
m.historylist=histlist
writereg("history","searchhist",arraytostring(histlist))



function AddHistory(id,histlist) as object
flag=0
for i=0 to histlist.count()-1
if id=histlist[i]
flag=1
end if
next i

if flag <> 1 then
histlist.unshift(id)
if histlist.count() > 10
histlist.pop()
end if
end if
m.mixhist=histlist
writereg("history","mixhist",arraytostring(histlist))
return m.mixhist
end function


function arraytostring(array as object) as string
str=""
for each element in array
if element <> invalid
str=element+","+str
end if
next
return left(str,len(str)-1)
end function


function loadsearchHistory() 
if not checkreg("history","searchhist") then
?"no search history in the registry"
createregsection("history","searchhist", "")
else
?"found search history, loading"
histemp=box(readreg("history","searchhist").tokenize(","))
i=histemp.count()-1
j=0
while true
if i=-1 or j > histemp.count() -1
exit while
end if
m.historylist[j]=histemp[i]
i=i-1
j=j+1
end while
end if
end function


function createregsection(secname as string,keyname as string, keyvalue as string)
registry=createobject("roregistry")
section=createobject("roregistrysection",secname)
section.write(keyname,keyvalue)
end function

function checkreg(secname as string,keyname as string) as boolean
registry=createobject("roregistry")
section=createobject("roregistrysection",secname)
return section.exists(keyname)
end function

function readreg(secname as string, keyname as string) as string
registry=createobject("roregistry")
section=createobject("roregistrysection",secname)
return section.read(keyname)
end function

function writereg(secname as string, keyname as string, keyvalue as string) as boolean
registry=createobject("roregistry")
section=createobject("roregistrysection",secname)
section.write(keyname,keyvalue)
end function

function deletekey(secname as string,keyname as string) as boolean
registry=createobject("roregistry")
section=createobject("roregistrysection",secname)
return section.delete(keyname)
end function

function deleteSection(secname as string) as boolean
registry=createobject("roregistry")
return registry.delete(secname)
end function

function regflush()
registry=createobject("roregistry")
registry.flush()
end function

Re: Store Search History

RokuJoel, I didn't know about tokenize but that makes it quite easy thanks.

RokuChris, thanks for the XML suggestion.

Re: Store Search History

Is there a simple way to search history by date or otherwise? We installed YouTube on the roku and we want to know what has been watched. I am not a programmer. Thank you in advance
