Try this,

IDocument* doc = Utils<ILayoutUIUtils>()->GetFrontDocument();

InterfacePtr<IPageList> pagelist(doc, IID_IPAGELIST);
int32 count = pagelist->GetPageCount();

I doubt the code you pasted is the one that you are running in your plugin, looking at it i suspect it will even compile. You can't join a string value with an integer as you have done inside CAlert. See screenshot below

Also your explanation is a bit confusing, you say you get 2 as the result but null as well. Do both these scenarios happen with the same document randomly? If not then what different do you do when the result is null? Are you able to debug your code?

Please answer every question i have asked for helping us help you, giving cryptic one line answers with a different code everytime which apparently is wrong and hence not working in the first place just wastes time all around.

Hi together,

I'm no SDK developer, just know my way arround in the ExtendScript DOM.

From that I know that the value of the page length can also obtained by a preference of the document:

documentPreferences.pagesPerDocument

Important note: pagesPerDocument is read/write

So it can be used at any time, when creating a document or even after a document is created, to change the number of document pages:

app.documents.add
(
{ documentPreferences : { pagesPerDocument : 10 } }
);

app.documents[0].documentPreferences.pagesPerDocument = 5 ;

And it's a very straight forward way to get the number of pages without asking the list of document pages:

var numberOfPagesInDoc = app.documents[0].documentPreferences.pagesPerDocument;

It should be possible to access the equivalent of pagesPerDocument with the SDK as well…

Hi Uwe,

You are right, that would correspond to GetNumPagesPref method in IPageSetupPrefs interface on the kDocWorkspaceBoss boss class. The issue is not about finding a new way to do it, since the code shared already seems to work fine. I have tested the code and it seems to be working fine

I have run the code for the first time it provide the correct value but while running the code it provides an null value is this used method is correct or not. If it goes wrong please suggest me with the solution. But it gives the exact output as "2"

IDocument* doc = Utils<ILayoutUIUtils>()->GetFrontDocument();
if(doc)
{
InterfacePtr<IPageList> pagelist(doc, IID_IPAGELIST);
int32 count = pagelist->GetPageCount();
CAlert::WarningAlert("Values:"+count);

}

Now output recieved for me is attached for the reference
