GetSelMarkupsOnly causes error

[chrisbouwman]

When I try to set GetSelMarkupsOnly true, the control returns "Invalid argument".
Code: ctrl.SetDocumentProperty(docID, "GetSelMarkupsOnly", "True", 0)

I also tried "true", """true""" and 1 instead of "True" without succes.

Hello chrisbouwman,

Can you try setting
ctrl.SetDocumentProperty(docID, "GetSelMarkups", "true");
Instead and see if that will work.

I noticed both in the Viewer Manual and am not sure if GetSelMarkupsOnly is not a deprecated name that has not been properly updated in the manual.

Best,
Stefan

Hello Stefan,

Strange...
ctrl.SetDocumentProperty(docID, "GetSelMarkups", "true") still returns "Invalid argument"

Hi chrisbouwman,

Thanks for trying that.
Can we get a bit bigger snippet of your code as I'd like to pass this to my colleagues in the dev team and the more info they have the easier it would be to fix your problem. Please also make sure no licensing info is visible!

Best,
Stefan

Hello Stefan,

This is the Sub that causes trouble:
Public Sub PDFXViewer_OnEvent(ByVal sender As System.Object, ByVal e As AxPDFXCviewAxLib._IPDFXCviewEvents_OnEventEvent)
If e.type = PDFXCviewAxLib.PXCVA_EventTypes.PXCVA_OnNamedNotify Then
Dim AnnotIsSelected As Boolean = False
Dim docID As Integer = 0
sender.getActiveDocument(docID)

If docID > 0 Then
sender.SetProperty("Notifications.Selection.Filter", -1, 0)
Dim selectedAnnotPageAndIndexOnPage As Object = Nothing
Try
sender.SetDocumentProperty(docID, "GetSelMarkups", "true")
sender.DoDocumentVerb(docID, "", "GetSelectedAnnot", "", selectedAnnotPageAndIndexOnPage, 0)
If selectedAnnotPageAndIndexOnPage.length > 0 And selectedAnnotPageAndIndexOnPage(0) >= 0 Then
AnnotIsSelected = True
End If
Catch ex As Exception
ShowErrorMessage(sender, ex)
End Try
End If
End If
End Sub

Kind regards,
Chris

Thanks Chris,

One of my colleagues will review this shortly and we will post back in this topic any advise we have.

Hi chrisbouwman,

Thank you for your post.
Please use the property "GetSelMarkupsOnly" and "GetSelectedAnnot" in the following way.

Code: Select all

//pseudo-code follows

//1. Register notifications
SetProperty("Notifications.Selection.Filter", "All", 0);

//2. Set behavior of GetSelectedAnnot 
SetDocumentProperty(docID, "GetSelMarkupsOnly", 1, 0);

//3. Event Handler
function OnEvent(Type, Name, ....)
{
      if (Type == PXCVA_OnNamedNotify)
	{		
		if(Name == "Notifications.Selection")
		{		
                        //...
			DoDocumentVerb(docID, NULL,"GetSelectedAnnot", NULL, &vDataOut, 0);
                        //...			
		}
	}
}

I verified the code above works.
Also, the property "GetSelMarkups" is not currently available
Thanks.

Sincerely,

[chrisbouwman]

Hi Nico,

This code still generates an error. I'll set up a new VB project with just the necessary code and see if it works there.

When I have result I'll post them here.

Kind regards,

Looking forward to the results of your tests chrisbouwman!

Best,

Hi chrisbouwman,

Please make sure you are using the latest build which is 2.5.210.0.
You can download the latest build from here: https://www.pdf-xchange.com/product ... ctivex-sdk.
Thanks.
Sincerely,

[chrisbouwman]

Hello Nico, Stefan,

Latest build did the trick. Thanks for the tip.

Still, there is one strange behaviour. Often when I select an annotation, the name of the event fired is "Global::FocusGained" instead of "Notifications.Selection". When I remove the condition "If e.name = "Notifications.Selection"" my code works fine, but its not the nicest way.

The annotations are shown using JavaScripts "this.importAnFDF" and "var annot = this.addAnnot({...}".

Hi chrisbouwman,

Thank you for your post.

Often when I select an annotation, the name of the event fired is "Global::FocusGained" instead of "Notifications.Selection". When I remove the condition "If e.name = "Notifications.Selection"" my code works fine, but its not the nicest way.

The "Global::FocusGained" event is triggered when a control or any window from a control gains focus or already has the input focus (see Viewer ActiveX Manual, section 2.2.4.1), therefore anytime when you select an annotation, this event will be fired before "Notifications.Selection". In addition, if you remove the condition "If e.name = "Notifications.Selection"", you cannot detect when the "Notifications.Selection" event happens, which was your goal (I believe), therefore you don't have to remove it. If you print all the events that are detected at the event handler function, you will be able to see this behavior.
Thanks.

Sincerely,

Hello Nico,

Thanks for your answer. It's the behaviour I expected but that did not occur. Now I've put the line SetProperty("Notifications.Selection.Filter", "All", 0) after other SetProperty lines in my code and it works.

Thank you for you're support!

Kind regards,
Chris

That's great to hear Chris.

I'll make sure Nico hears.
