I am new to iOS development. I am working on an ePUB reader app for iPad.
The server sends me file with .acsm extension. Its an XML formatted file. Now I need to parse this acsm file and download the book.
The server side developer says that its working and he's able to download the ebook using Adobe Digital Editions.
What should I do to download the actual book and display it?
These are the contents of acsm file:

I am writing a function or a commandlet (I want to call it Set-Metadata) that will allow me to attach metadata information to directories and files. Its for a file manager columns that expect ADS data
I am currently stuck on the logic part.
Before I write any metadata to a file via its NTFS ADS I would first like to check if the file has a specific stream so that I don't overwrite anything and instead append text to the stream.
function Set-MetaData(
[Parameter(Mandatory=$true, ValueFromPipeline=$true)]
[string]
$Path,
[Alias("C", "Cat")] #Replace Column Content
[String]$Category,
[Alias("PC", "PCat")] #Prefix to the content in Column
[String]$PCategory,
[Alias("SC", "SCat")] #Suffix to the content in Column
[String]$SCategory){
process {
Switch ($PSBoundParameters.Keys){
'Category'{
}'PCategory'{
}'SCategory'{
if(...) #file has a stream called "multitags.txt"
# Add-Content -Path $Path -Stream multitags.txt -Value $Category
}}
}
I have taken the liberty to cross post this question on other forums as well.
Any help would be greatly appreciated!
I have one requirements as below. Suppose I have a column with below values
rowno Column
1 MS Teams slack skype
2 slack
3 skype
I want to split the first row as below
rowno Column
1 MS Teams
1 slack
1 skype
2 slack
3 skype
How I can not use sub field function since it will split MS Teams to MS ,Teams. Instead can I use wildmatch? Please suggest how I can achieve this in Qlik Sense?
I'd probably do it in 2 parts... first to replace the MS Teams value with MS_Teams and then do the subfield. You could add another part to get rid of the _ at the end.
Table:
Load
rowno,
subfield(Column_clean,' ') as Column;
Load
rowno,
replace(Column,'MS Teams','MS_Teams') as Column_clean
from source;
I am unable to update content in xml tag using xml Twig module.
Here is my xml file :-
<?xml version="1.0"?>
<test customerProprietary="false">
<classes>
<class name="new" />
</classes>
<chars>
<log>false</log>
</chars>
</test>
Code snippet:-
my $twig = XML::Twig->new(
pretty_print => 'indented',
twig_handlers => {
log => sub {
if ($_->text eq 'true'){
exit;
}
else{
print $_->text;
subp4open($xmlfile);
$_->set_text( 'true' );
exit;
}
}
);
$twig->parsefile($script_path);
$twig->print_to_file($script_path);
i have to update <log>false</log> to <log>true</log>. Am i missing something here?
That's because exit exits the program, so print_to_file is never reached. Remove the exits. You can replace them with returns, but they aren't needed.
When I run into these sorts of things, I like to put a statement like say "This far" to see that I've made it to a particular part of the code:
say "About to parse file";
$twig->parsefile($script_path);
say "About to print file";
$twig->print_to_file($script_path);
In your handler, there are some things that you can improve. Since you don't want to do anything in the case that the value is already true, don't even think about that case:
log => sub {
if ($_->text ne 'true'){
print $_->text;
subp4open($xmlfile);
$_->set_text( 'true' );
}
},
I might be inclined to always update the value if you want them all to be true. I don't care what it was before as long as I get what I want at the end (although this way tweak your source control a bit):
log => sub { $_->set_text( 'true' ) },
Also, I might consider doing any Perforce magic outside of the twig handler. Get the lock on the file before you give it to Twig. If you can't get that lock, you might as well not process it. Then, remember to release it later. If you do all of those operations close together, you're less likely to forget a step.
According to this scenario.
Used to test it using sample message - text. And it works fine.
I should implement that by using buttons (callbacks).
The real problem is :
Sample text :
context.Activity.Id
"mid.$cAAOmNGtaSJ9i1_f223cprKylFOpb"
on button click (callback) :
context.Activity.Id
"9Yw5TAcq1qr"
This is the code i used to post human support button :
msg.AttachmentLayout = AttachmentLayoutTypes.Carousel;
msg.Attachments = new List<Attachment>();
ThumbnailCard thumbnailCard2 = new ThumbnailCard()
{
Buttons = new List<CardAction>
{
new CardAction ()
{
Value = "Method_Support",
Type = "postBack",
Title = "Human Support"
},
},
};
msg.Attachments.Add(thumbnailCard2.ToAttachment());
await context.PostAsync(msg);
It returns activity.Id : 9Yw5TAcq1qr - as i already mentioned. I can't use that id to query Facebook graph api.
What's the best way to handle scenario like this ?
Is it possible to render all incoming messages as native Facebook (sample-text) messages ?
Is it possible to make call to graph api using callback's activity.id ?
Following my previous answer about how to link the Activity from botFramework to the messages in Conversation in Facebook's Graph API, I had a look to your problem.
Analysis
From my point of view, there is a strange thing in this Activity.Id value because on Facebook's side, all messages have the same id format, even for callbacks.
Here is a capture of 2 messages (1st one is the latest one) from Facebook Graph API:
{
"data": [{
"messages": {
"data": [
{
"id": "m_mid.$cAAC3Jml0RcBi2JK3Clcp01uu8FFe",
"message": "Human support"
},
{
"id": "m_mid.$cAAC3Jml0RcBi2I5bXlcp0kScM7af",
"message": ""
}
]
},
"id": "t_mid.$..."
}]
}
Message with empty text is a ThumbnailCard with a CardAction inside (type = postback, Value = Method_HumanSupport)
Human support is what is sent on the click on the CardAction
What is surprising is that on the bot side, for those 2 messages we have the following values for Activity.Id:
For "id": "m_mid.$cAAC3Jml0RcBi2I5bXlcp0kScM7af" (my Thumbnail) => mid.$cAAC3Jml0RcBi2I5bXlcp0kScM7af, so it's matching
For "id": "m_mid.$cAAC3Jml0RcBi2JK3Clcp01uu8FFe" (the callback) => DWhE2C0VO79, no match at all
For information my ThumbnailCard is made like the OP said:
var msg = context.MakeMessage();
msg.AttachmentLayout = AttachmentLayoutTypes.Carousel;
msg.Attachments = new List<Attachment>();
msg.Text = "updates & support";
ThumbnailCard thumbnailCard2 = new ThumbnailCard()
{
Buttons = new List<CardAction>
{
new CardAction ()
{
Value = "Method_HumanSupport",
Type = "postBack",
Title = "Human support"
}
}
};
I will add a question on Bot Framework GitHub Project.
Edit: issue logged: https://github.com/Microsoft/BotBuilder/issues/2950
Workaround
There are several workaround that will depend on your global use cases: you could try to log the Activity.Id of a "normal" message in the discussion and use this value later when your callback is clicked, or you can also try to change your flow to avoid making this kind of link between Bot Framework and Facebook Graph API.
i want the solution of below question, i dont know how to store sinup information in Plist, can any one knows please help.
Thanks in advance
Use Dummy data but the dummy data must not be in the code ,it should either be in an external file (plist/xml) or in a separate constant file.This improves the code management.
All screens must comply to Portrait and Landscape View Mode
1. The App will begin with the Login Screen, The screen should be having same functionality as any website.
a. Login
b. Sign Up
c. Maximum Tries (3) then lock the app
d. Requires Answer to secret question to unlock which will be accepted in sign up
If you are looking for storing small data like user credentials look for NSUserDefault.
For automatic login, if the user has logged in previously look this.
You can create a new .plist file to store the information.
Add New File in your project, of type "Property list". Its under the "Resource tab", on "Mac OS X" in the left pane of your xcode.
Once created, Now add new items in to it. The "Key" will be used the retrieve the value through the coding.
To retrieve the values in the coding, from .plist file, you can use this code:
NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
NSDictionary* defaultSettings = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"YOUR_PLIST_FILE_NAME.plist" ofType:nil]];
[defaults registerDefaults:defaultSettings];
NSString *sName = [defaultSettings objectForKey:#"Name"]; //the Name is the Key in .plist file, so its corresponding value will be fetched and store in sName variable
NSString *defaultDomain = [defaultSettings objectForKey:#"domain"];
I hope it helps :)
