How to add border to cell with openxml in PowerPoint?

I am trying to change the top border of a table in PowerPoint via OpenXml, but it has not worked for me. The cell currently has a left, right, and bottom border, but when I try to copy the bottom border and add it to the top border, PowerPoint does not reflect the change.
What do I need to change or am I doing wrong to make it work?
I currently have the following code to copy the bottom border and replace it.
BottomBorderLineProperties btp = (BottomBorderLineProperties)celda.TableCellProperties.BottomBorderLineProperties.CloneNode(true);
TopBorderLineProperties tbp = new TopBorderLineProperties()
{
Alignment = btp.Alignment,
CapType = btp.CapType,
CompoundLineType = btp.CompoundLineType,
MCAttributes = btp.MCAttributes,
Width = btp.Width
};
foreach(OpenXmlElement element in btp.ChildElements)
{
tbp.Append(element.CloneNode(true));
}
celda.TableCellProperties.TopBorderLineProperties = tbp;
Thanks!
PS: Sorry for my english

In order to set the top border of a cell in the middle of a PowerPoint table, you have to complete 2 steps:
Step 1: set the bottom border of the cell directly above the cell in question and
Step 2: set the top border of the cell in question (you have that part)
I determined this by using the OpenXML Productivity Tool. I took a simple 1 slide PowerPoint file named Before.pptx with a table cell that had the left, bottom and right borders.
Then I added the top border (using PowerPoint 2016) and saved the file as After.pptx. I then used the Productivity Tool to diff the 2 files and reverse engineer the C# code required to make Before.pptx look like After.pptx. The important code you need is displayed here:
//STEP 1 CODE STARTS HERE
A.Table table1=graphicData1.GetFirstChild<A.Table>();
A.TableRow tableRow1=table1.GetFirstChild<A.TableRow>();
A.TableRow tableRow2=table1.Elements<A.TableRow>().ElementAt(1);
A.TableCell tableCell1=tableRow1.Elements<A.TableCell>().ElementAt(2);
A.TableCellProperties tableCellProperties1=tableCell1.GetFirstChild<A.TableCellProperties>();
A.BottomBorderLineProperties bottomBorderLineProperties1 = new A.BottomBorderLineProperties(){ Width = 12700, CapType = A.LineCapValues.Flat, CompoundLineType = A.CompoundLineValues.Single, Alignment = A.PenAlignmentValues.Center };
A.SolidFill solidFill1 = new A.SolidFill();
A.SchemeColor schemeColor1 = new A.SchemeColor(){ Val = A.SchemeColorValues.Text1 };
solidFill1.Append(schemeColor1);
A.PresetDash presetDash1 = new A.PresetDash(){ Val = A.PresetLineDashValues.Solid };
A.Round round1 = new A.Round();
A.HeadEnd headEnd1 = new A.HeadEnd(){ Type = A.LineEndValues.None, Width = A.LineEndWidthValues.Medium, Length = A.LineEndLengthValues.Medium };
A.TailEnd tailEnd1 = new A.TailEnd(){ Type = A.LineEndValues.None, Width = A.LineEndWidthValues.Medium, Length = A.LineEndLengthValues.Medium };
bottomBorderLineProperties1.Append(solidFill1);
bottomBorderLineProperties1.Append(presetDash1);
bottomBorderLineProperties1.Append(round1);
bottomBorderLineProperties1.Append(headEnd1);
bottomBorderLineProperties1.Append(tailEnd1);
tableCellProperties1.Append(bottomBorderLineProperties1);
//STEP 1 CODE ENDS HERE
//STEP 2 CODE STARTS HERE
A.TableCell tableCell2=tableRow2.Elements<A.TableCell>().ElementAt(2);
A.TableCellProperties tableCellProperties2=tableCell2.GetFirstChild<A.TableCellProperties>();
A.BottomBorderLineProperties bottomBorderLineProperties2=tableCellProperties2.GetFirstChild<A.BottomBorderLineProperties>();
A.TopBorderLineProperties topBorderLineProperties1 = new A.TopBorderLineProperties(){ Width = 12700, CapType = A.LineCapValues.Flat, CompoundLineType = A.CompoundLineValues.Single, Alignment = A.PenAlignmentValues.Center };
A.SolidFill solidFill2 = new A.SolidFill();
A.SchemeColor schemeColor2 = new A.SchemeColor(){ Val = A.SchemeColorValues.Text1 };
solidFill2.Append(schemeColor2);
A.PresetDash presetDash2 = new A.PresetDash(){ Val = A.PresetLineDashValues.Solid };
A.Round round2 = new A.Round();
A.HeadEnd headEnd2 = new A.HeadEnd(){ Type = A.LineEndValues.None, Width = A.LineEndWidthValues.Medium, Length = A.LineEndLengthValues.Medium };
A.TailEnd tailEnd2 = new A.TailEnd(){ Type = A.LineEndValues.None, Width = A.LineEndWidthValues.Medium, Length = A.LineEndLengthValues.Medium };
topBorderLineProperties1.Append(solidFill2);
topBorderLineProperties1.Append(presetDash2);
topBorderLineProperties1.Append(round2);
topBorderLineProperties1.Append(headEnd2);
topBorderLineProperties1.Append(tailEnd2);
tableCellProperties2.InsertBefore(topBorderLineProperties1,bottomBorderLineProperties2);
I ran the code above against my Before.pptx file and the border was complete.
In an effort to double check that the two steps are necessary, I commented out the Step 1 code and ran it against a fresh version of Before.pptx file and the top border was missing. This verifies the problem you were seeing. Therefore, the two steps are necessary to paint the one border.

Saving chart into image file with axis

can you tell me what is wrong with my code? I want to generate chart image in console application over System.Windows.Forms.DataVisualization.Charting library... Following code generate me chart only with columns, but I need chart with axis. Any ideas?
Chart chart = new Chart();
chart.Size = new System.Drawing.Size(2000, 500);
ChartArea area = new ChartArea();
chart.ChartAreas.Add(area);
chart.BackColor = System.Drawing.Color.Transparent;
chart.ChartAreas[0].AxisX.MajorGrid.Enabled = false;
chart.ChartAreas[0].AxisY.MajorGrid.Enabled = false;
chart.ChartAreas[0].AxisX.Title = "sasdasdasd";
Series series = new Series()
{
Name = "series2",
IsVisibleInLegend = false,
ChartType = SeriesChartType.Column
};
chart.Series.Add(series);
foreach (CnbItem item in items)
{
DataPoint p1 = new DataPoint(0, Double.Parse(item.Kurz));
p1.Color = System.Drawing.Color.LightBlue;
p1.AxisLabel = item.Kod;
p1.LegendText = item.Kod;
p1.Label = item.Kurz;
series.Points.Add(p1);
}
string filename = "D:\\Chart.png";
chart.SaveImage(filename, ChartImageFormat.Png);

Update: Setting the the Chart's Backcolor to Transparent actually works just fine. However some image viewers do not display transparency; I use Irfanview as my default viewer and it is one of those which can't. I suspect yours also misses transparency..
Instead all transparency is rendered as black, so unless you have a non-black line color.. your axes and labels etc.. seem to be gone. Paint (on W10) is another one but renders transparency to white, so the black pixels are at least visible.
The below image is from Photoshop, which, of course, doesn't have that problem..

Button image sides cropped

I'm trying to fit image to button perfectly.
But the image is cropped on its right and bottom faces, see attached print screen:
I edited the button as follows:
var l_oStopImage = Image.FromFile(#"C:\Users\AmitL\Downloads\Button-2-stop-icon72p.png");
var l_oStopPic = new Bitmap(l_oStopImage , new Size(btnStopOperation.Width, btnStopOperation.Height));
btnStopOperation.Image = l_oStopPic ;
btnStopOperation.ImageAlign = System.Drawing.ContentAlignment.MiddleCenter;
btnStopOperation.TabStop = false;
btnStopOperation.FlatStyle = FlatStyle.Flat;
btnStopOperation.FlatAppearance.BorderSize = 0;
I also tried to edit the BackgroundImageLayout but none of the ImageLayouts fixed the problem..
Any suggestions?
Thanks in advance

You should use stretch, I suggest in designtime (this is not java where you have to add elements by code):
this.buttonOk.BackColor = System.Drawing.SystemColors.MenuHighlight;
this.buttonOk.BackgroundImage = ((System.Drawing.Image)(resources.GetObject("buttonOk.BackgroundImage")));
this.buttonOk.BackgroundImageLayout = System.Windows.Forms.ImageLayout.Stretch;
this.buttonOk.DialogResult = System.Windows.Forms.DialogResult.Cancel;
this.buttonOk.Location = new System.Drawing.Point(475, 15);
this.buttonOk.Name = "buttonOk";
this.buttonOk.Size = new System.Drawing.Size(50, 50);
this.buttonOk.TabIndex = 11;
this.buttonOk.UseVisualStyleBackColor = false;
this.buttonOk.Click += new System.EventHandler(this.buttonOk_Click);
And it will work, done it many times before
I got this code from my own working Form1.Designer.cs but because of that: please use the Visual Studio designer and don't try to write all this code / logic in your constructor or something.

The problem is because you are showing an image with the same size as your button.
When you want an image fit in your button, the width and height of image should be at least 1 point less than your button size. (or in other word, you can set your button width and height 1 point more than the image size).
So you can change your code to this:
var l_oStopPic = new Bitmap(l_oStopImage ,
new Size(btnStopOperation.Width-1, btnStopOperation.Height-1));

Custom tile generates a System.OutOfMemoryException exception in wp8

Has anyone got any idea why I'm getting an OutOfMemoryException when I'm creating my custom tile?
I'm trying to create custom images for my primary tile on a windows phone 8 app from a ScheduledAgent. The error doesn't occur until my very last line of code is executed which is the NotifyComplete().
Here is the code (Not the cleanest but ok for prototyping I guess). This code only handles the wide tile and it tries to load an image an image downloaded from a website and then it tries to render a logo and a description over this image.
Here is the code:
private void CreateTiles()
{
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
for (int i = 0; i < 2; i++)
{
var bmp = new WriteableBitmap(691, 336);
var articleImg = new BitmapImage(new Uri(articles[i].ImageFilename, UriKind.Relative));
var articleImage = new Image { Source = articleImg };
articleImage.Stretch = Stretch.UniformToFill;
articleImg.CreateOptions = BitmapCreateOptions.None; // Force the bitmapimage to load it's properties so the transform will work
var bmpLogo = new WriteableBitmap(100, 100);
var logoImg = new BitmapImage(new Uri("/Assets/Tiles/FlipCycleTileSmall.png", UriKind.Relative));
var logoImage = new Image { Source = logoImg };
logoImage.Opacity = 1.0;
logoImg.CreateOptions = BitmapCreateOptions.None; // Force the bitmapimage to load it's properties so the transform will work
var articleBannerGrid = new Grid();
articleBannerGrid.Background = ColorExtensions.ToSolidColorBrush("#000F558E");
articleBannerGrid.Opacity = .5;
articleBannerGrid.Height = 100;
articleBannerGrid.VerticalAlignment = VerticalAlignment.Bottom;
articleBannerGrid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(100) });
articleBannerGrid.ColumnDefinitions.Add(new ColumnDefinition());
articleBannerGrid.Children.Add(logoImage);
Grid.SetColumn(logoImage, 0);
var textBlock = new TextBlock();
textBlock.Text = articles[i].Description;
textBlock.FontWeight = FontWeights.Bold;
textBlock.Margin = new Thickness(10, 5, 30, 5);
textBlock.TextWrapping = TextWrapping.Wrap;
textBlock.Foreground = new SolidColorBrush(Colors.White); //color of the text on the Tile
textBlock.FontSize = 30;
textBlock.Opacity = 1.0;
var articleTextGrid = new Grid();
articleTextGrid.Height = 100;
articleTextGrid.VerticalAlignment = VerticalAlignment.Bottom;
articleTextGrid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(100) });
articleTextGrid.ColumnDefinitions.Add(new ColumnDefinition());
articleTextGrid.Children.Add(textBlock);
Grid.SetColumn(textBlock, 1);
var canvas = new Grid();
canvas.Width = articleImg.PixelWidth;
canvas.Height = articleImg.PixelHeight;
canvas.Children.Add(articleImage);
canvas.Children.Add(articleBannerGrid);
canvas.Children.Add(articleTextGrid);
bmp.Render(canvas, null);
bmp.Invalidate(); //Draw bitmap
FileStream fs = new FileStream(articles[i].ImageFilename, FileMode.Create);
bmp.SaveJpeg(fs, bmp.PixelWidth, bmp.PixelHeight, 0, 100);
fs.Close();
fs.Dispose();
articleImage = null;
articleImg = null;
}
//GC.Collect();
//GC.WaitForPendingFinalizers();
ShellTile TileToFind = ShellTile.ActiveTiles.FirstOrDefault();
if (TileToFind != null)
{
string title = articles[0].Tag;
string backTitle = articles[1].Tag;
string content = articles[0].Description;
string backContent = articles[1].Description;
FlipTileData tileData = new FlipTileData()
{
Title = title,
BackTitle = backTitle,
BackContent = backContent,
WideBackContent = backContent,
BackgroundImage = new Uri(articles[0].ImageFilename, UriKind.Relative),
BackBackgroundImage = new Uri(articles[1].ImageFilename, UriKind.Relative),
WideBackgroundImage = new Uri(articles[0].ImageFilename, UriKind.Relative),
WideBackBackgroundImage = new Uri(articles[1].ImageFilename, UriKind.Relative),
};
TileToFind.Update(tileData);
}
NotifyComplete();
});
}
I assume that it is the correct place to generate the custom tile i.e. ScheduledAgent.
I found an article Dynamic Live Tile issue WP8 [WriteableBitmap] on the Nokia website with the same problem but no solution there either.
I'll continue debugging this tomorrow by removing everything and adding each bit individually step by step to see if I can spot anything but if anyone has got any suggestion or solution, I'd appreciate if you could help.
If I'm going about it the wrong way, please let me know what's the best method to update tiles in the scheduled agent.
Thanks.

WP BackgroundAgents have a small memory cap. 20MB for WP8 without update 3 and 25 for WP8 with Update 3.
I would suggest that you create a another project and add Coding4Fun toolkit and MemoryCounter in to your page and then add the code in your BackgroudAgent to the sample page and try to create the tiles. Then look at how much memory it uses. I think amount of memory usage is higher than the 20/25MB cap. if so you have to find a way to reduce it.

As usual, Microsoft is omitting critical information from its documentation.
After reducing the size of my tile from 691x336 to 336x165, it worked, so it got me thinking and I thought that the size recommended by Microsoft in this article Flip Tile template for Windows Phone 8 for wp8 and wp8.1 seemed excessive, so I did a bit more research and this is when I found this excellent explanation in an article in stackoverflow i.e.
Windows Phone 8 Startscreen Tile sizes and margins
This clearly states the size of the tiles but not based on OS versions but based on screen resolutions.
In my test environment, I was using the default 'Emulator WVGA 512MB' and again by default the screen size is 480x800, so taking into account the information provided in the answer of this article, my tile size should have been 430x210.
I resized my (already reduced) tile back up to 430x210, and it still worked.
While there is a memory cap of 20/25Mb depending on OS and patch being used, which probably causes many problems from the various articles I've read on the web, in my instance I believe it was more likely to have been affected by tile size being incorrect, and therefore the additional memory, or lack thereof.
I will update this article once I get to using 8.1 in my IDE with a larger resolution but for now, I have to assume that it was definitely related to the size of my tile.
I'll definitely make sure to add code to create tile based on os, patch and resolution being used. Bit of a pain to best honest!
Hope this helps.

Removing .Diffuse colours from an FBX model

I am currently working on an AR project, based around the original 'Tutorial 8 - Marker Tracking' program supplied by GoblinXNA. I've had a play around with it, and replaced the models with some of my own designs, saved as .fbx format. The problem I am having though is that the .Diffuse extension is replacing the the original colours of the model with red; altering the colours makes no difference, only changing the colour and not allowing me to have the models original appearance, and removing the .Diffuse line of code only makes the model turn to shades of grey and black (I'm guessing this is something to do with CreateLights() method?)
In any case, here is the code form the object; any help would be much appreciated!
ModelLoader mLoader = new ModelLoader(); //self explanatory
Model flagModel = (Model)mLoader.Load("", "FlagModelAsset2");
flagNode = new GeometryNode("FlagModelAsset2");
flagNode.Model = flagModel;
flagNode.AddToPhysicsEngine = true;
flagNode.Physics.Shape = ShapeType.Box;
flagNode.Model.ShadowAttribute = ShadowAttribute.ReceiveCast;
flagNode.Model.Shader = new SimpleShadowShader(scene.ShadowMap);
//TransformNode flagTransNode = new TransformNode();
//flagTransNode.Translation = new Vector3(0, 0, 0); //position of flag
//flagTransNode.Scale = new Vector3(1f, 1f, 1f); //size of flag
toolbarMarkerNode = new MarkerNode(scene.MarkerTracker, "ALVARToolbar.xml");
Material flagMaterial = new Material();
flagMaterial.Diffuse = new Vector4(0.5f, 2, 0, 1); //colour of flag
flagMaterial.Specular = Color.White.ToVector4();
flagMaterial.SpecularPower = 10;
flagNode.Material = flagMaterial;
groundMarkerNode.AddChild(flagNode);
scene.RootNode.AddChild(toolbarMarkerNode);
//flagNode.AddChild(flagTransNode);
NewtonPhysics.CollisionPair pair = new NewtonPhysics.CollisionPair(flagNode.Physics, sphereNode.Physics);
((NewtonPhysics)scene.PhysicsEngine).AddCollisionCallback(pair, BoxSphereCollision);
}

It was the materials; removing this and adding the code below allows the use of the textures from the original imported file
((Model)flagNode.Model).UseInternalMaterials = true;
