Hello Aspose Team

Sorry to say that aspose slide Locking is not working as expected

We have tried code from
http://www.aspose.com/docs/display/slidesnet/Applying+Protection+to+Presentation
but it can be easily unlocked. :(
just copy any text from somewhere and paste it on locked slides (we tried shortcut for pasting CRTL +V)
you can see it will get unlocked please try

Awaiting Reply
Site is going live this week

Thanking you

Hi Praveen,

I have observed your comments and request you to please share a working sample project (not complete on but reproducing the issue) in which you are applying locks and creating a unlocked slide using Ctrl+V in a new presentation instance. Please also share the created presentation as well. I will investigate this on my end to help you further.

Many Thanks,

this is the code we tried

Hi Praveen,


I have observed the sample code and source presentation. The generated presentation locks all the slide shapes and they remain intact even if you copy slide with locked shapes to another presentation even. Your requirement that the when you copy paste the text from some where and paste on the slide on which shapes are locked then it is not going to ensure the addition in that slide. The concept is when you lock shapes on slide the locking ensures the integrity of those shapes only which locking is applied. There is no property of making the complete slide read only. However, you can set the complete presentation to ready only mode as it is done in PowerPoint. I hope this will clarify the concept to you. This is not an issue.

Many Thanks,

We bought Aspose.Net primarily for its locking feature.

We cannot make a presentation ‘read-only’ as it prompts for password/read-only confirmation during open, which is against our requirement specification.

In fact Aspose.Net locking is satisfactory except the following bug. So we expect this to get fixed.

1. An Aspose.Net locked slide:

See the first attachment 1.png

2. Copying text from a text editor:

See the second attachment 2.png

3. Pasting text onto Aspose.Net locked slide

See the third attachment 3.png

4. Pasted:

See the fourth attachment 4.png

5. NOW, Locking lost!

See the fifth attachment 5.png

Requesting a fix for this.

Thanking you,

Praveen

Hi Praveeen,

I have observed the images shared by you and have tried modifying the locked presentation by copying text from text editor and directly pasting that on slide. There is no issue observed on my end and the shapes remain locked. I have used Aspose.Slides for .NET 15.4.0 on my end. For your kind reference, I have attached the source presentation as well as updated generated presentation. Can you please try opening the output presentation on your end. If you are still able to reproduce the issue then please share the complete PowerPoint version number used on your end.

Many Thanks,

Hi Praveen,


Our product team has investigated the requirement on their end. Actually, there is the bug in PowerPoint that allows text to be edited in a locked shape. This bug exists consistently across PowerPoint 2013, 2010 and 2007.
The workaround is to create transparent rectangle and overlay it in front of the text box. Setup lock on the new rectangle shape. The text box should now not allow text editing. Please try using the following alternate on your end to serve the purpose.


IShape shape;
int shapesCount = slide.Shapes.Count;
for (int count = 0; count < shapesCount; count++)
{
shape = slide.Shapes[count];
if (shape is IAutoShape)
{
//Type casting to Auto shape and getting auto shape lock
IAutoShape Ashp = shape as IAutoShape;
IAutoShapeLock aShapeLock = Ashp.ShapeLock;
aShapeLock.PositionLocked = true;
aShapeLock.SelectLocked = true;
aShapeLock.SizeLocked = true;
//Workaround for text locking: create a transparent rectangle shape, overlay it in front of the text box and lock it
IAutoShape transpRect = slide.Shapes.AddAutoShape(ShapeType.Rectangle, Ashp.X - 5, Ashp.Y - 5, Ashp.Width + 10, Ashp.Height +10);
transpRect.FillFormat.FillType = FillType.Solid;
transpRect.FillFormat.SolidFillColor.Color = Color.Transparent;
transpRect.LineFormat.FillFormat.FillType = FillType.NoFill;
transpRect.ShapeLock.PositionLocked = true;
transpRect.ShapeLock.SelectLocked = true;
transpRect.ShapeLock.SizeLocked = true;
//
}
...
}

Many Thanks,
