table.AddRows fails

Hi,

I tried to create a simple table and after that add some rows.
If the table has only one row, table.AddRow() fails.

// doesn work
Table table = slide.Shapes.AddTable(400, 400, 5000, 3000, 2, 1);
table.GetCell(0, 0).TextFrame.Paragraphs[0].Portions[0].Text = “SampleText”;
table.AddRow();

// works fine
// AddRow() works if I create a table with 2 rows.
Table table = slide.Shapes.AddTable(400, 400, 5000, 3000, 2, 2);
table.GetCell(0, 0).TextFrame.Paragraphs[0].Portions[0].Text = “SampleText”;
table.AddRow();

Anybody an idea whats wrong?

Thanks,

Carsten

I receive the following exception:

You code is ok. It’s a problem with filling internal cache.
I will publish hot fix tomorrow.

Thanks Alexey for answer,

Another question (or possibly bug???) about tables.

I create a new table with 4 columns and 2 rows and try to set the columnWidth.
But it works only for the number of rows, in that example i can set the ColumnWith for the first two columns.


Table table = slide.Shapes.AddTable(300, 300, 2000, 1000, 4, 2);
for (int i=0; i<4; i++)
{
table.SetColumnWidth(i, 300);
}

Following exception occurs:
Wrong column index
System.Object {System.IndexOutOfRangeException} System.Object


And a question about AlternativeText:

slide.Shapes[0].AlternativeText

the property is read-only. Is there any chance to change the text?



Thanks,

Carsten

Dear Carsten,

I couldn’t reproduce your problem with last version. Please check 1.9.3 hot fix.

If you really need r/w access to AlternativeText we can implement it.

Thanks,

version 1.9.3 fixed the problem with setting column width Smile.

It would be helpful if you can implement r/w to AlternativeText, but only if the effort is not too high.

Carsten

Dear Carsten,

It’s not too difficult to implement r/w for AlternativeText but
could you tell me what you think about Tags at first?

You can read and write any number of custom text properties to each shape and slide.
These properties can be easily accessed from Aspose.PowerPoint and from MS PowerPoint.

Dear alcrus,

I am not sure what tags are. Can you give an example? I can create tags with Aspose for each shape, but I am not able to find them in Powerpoint.
When I search for “tag” in help of Powerpoint, i get only AlternativeText or SmartTags (is an Aspose-Tag a SmartTag?).
In Aspose help I found only "Represents a collection of a tags. ", but not what a tag is.

Here the way I create tags with Aspose:

slide.Shapes[textBoxIndex].Tags.Add(“TagName”, “TagValue”);


Carsten

Ah sorry, I found documentation of tags.

http://blogs.msdn.com/andrew_may/archive/2004/12/07/277696.aspx
"Tags are one of the rare pieces of the PowerPoint object model that doesn’t have a counterpart in the application’s user interface. Tags are a totally programmatic feature: you can’t get or set Tags objects except through code"

you wrote:
"These properties can be easily accessed from Aspose.PowerPoint and from MS PowerPoint."
Do I need an add-in to edit these tags in Powerpoint?


Carsten

another question about tags

adding tags to a textbox works fine.

i tried to add tags to table and i get always null reference exception

Table table = slide.Shapes.AddTable(300, 300, 500, 500, 2, 2);
table.Tags.Add("name", "value");

Dear Carsten,

Yes, this problem exists for dynamically created objects.
It will be fixed in the next hot fix.

Dear Alexey,

I have another problem with tables, again with AddRows().


if I create a new table in my code, AddRow() works

Table table = slide.Shapes.AddTable(300, 300, 500, 500, 10, 1);
table.AddRow(); // works fine


But if I use a table (with 10 columns) of a template, i receive a NullReferenceException.

Table ppTable = null;
for (int i=0; i<slide4.Shapes.Count; i++)
{
if (slide4.ShapesIdea is Table)
ppTable = (Table)slide4.ShapesIdea;
}
if (ppTable != null)
ppTable.AddRow(); // Object reference not set to an instance of an object.


And did you override Operator == for FontEntity?
i tried to check whether an instance of FontEntity is null or not
if (fontEntity == null) // throws a null reference exception
{

}

Carsten

hmm, Idea should be [ i ] Smile

Dear Carsten,

Is it a simple table or with merged cels?
Can you send me any example?

Yes, I overrided Operator== for FontEntity. Exception will be fixed.

Hi Alexey,

have a look at the presentation “test.ppt”. I can add rows to table on slide3, but not on slide2 (both are simple tables with 10 columns).

TestApplication.cs shows the way i add rows.
