Change annotations to locked

I want to change annotation on a document all to locked via code. I do know that there is already a post on the forum for this and I have looked at this as well as the Wiki, and have got the following code. However it does not seem to lock the annotations, so I guess I am doing something wrong?

Code: Select all

    Public Sub LockAnnotations()
        Dim pSInt As PDFXEdit.IPXS_Inst = DirectCast(Me.docPreview.Inst.GetExtension("PXS"), PDFXEdit.IPXS_Inst)
        Dim nID As Integer = Me.docPreview.Inst.Str2ID("op.annots.setProps", False)

        Dim Op As PDFXEdit.IOperation = Me.docPreview.Inst.CreateOp(nID)
        Dim input As PDFXEdit.ICabNode = Op.Params.Root("Input")

        Dim page As PDFXEdit.IPXC_Page = myDoc.CoreDoc.Pages(0)
        Dim nPageCount As UInteger = page.GetAnnotsCount()

        For i As UInteger = 0 To nPageCount - 1
            Dim annot As PDFXEdit.IPXC_Annotation = page.GetAnnot(i)
            input.Add().v = annot
        Next

        If input.Count = 0 Then
            Return
        End If

        Dim options As PDFXEdit.ICabNode = Op.Params.Root("Options")
        options("Flags").v = 128
        Op.Do()
    End Sub
Thanks for the help

Hello Simon,

Please specify a mask value of 0x00400000.

Cheers,
Alex

Alex,

Please could you give me an example of how to specify a mask value. I know this is probably coding 101, but would really help.

Code: Select all

Dim options As PDFXEdit.ICabNode = Op.Params.Root("Options")
options("Flags").v = "0x00400000"
Op.Do()
Thanks

Simon

Hello Simon,

The flags value was correct - though the options(""Mask") value needs to be 0x00400000

Cheers,
Alex

Alex,

I seem to get an error when setting the Mask value?

That's because it's not a string but a number value.

Hello,
can you help us about locking annotd, how we can lock a freetext without missing the possibility to change its properties (content properties i mean). see picture bellow.
Best regards

Hello Audros,

Do you want to achieve that in your SDK based product only? Or do you want to create such an annotation so that it would behave like that in all of the PDF readers/editors?

Cheers,
Alex

Hello Sir,
no,of course I'm looking for a solution to integrate into my SDK based product only.
Is that possible in all of the PDF readers/editors?
Thank you

Hello Audros,

You will have to catch the beforeOperationExecute event like described in this post:
viewtopic.php?f=66&t=31487&p=127569&hil ... ot#p127544
Then you will have to check whether it's a ModifyAnnots operation. If so, get the Mask from it and see what is currently being modified. If there is some flags that you do not need, then break the event and the operation execution.

Cheers,
Alex

Hello,
thanks, but i can't find an operation that can avoid changz text and allow modify properties(color style of text ....)
in addition to that, is there any way to do this for just our tool(bubble wih arrow that we create) and not for all freetext annotations
Thank you

Hello Audros,

This is the operation that you will have to monitor:

Hello Audros,

As I said before, if the operation has the flag that the contents were modified then you will have to break the operation.

Cheers,
Alex
