Remove borderline of textbox in Excel chart in C#, VB.NET
2014-08-12 07:57:21 Written by AdministratorThere is an article in the tutorials which demonstrates how to insert textbox with contents in Excel. Sometime back, a user of Spire.XLS wanted to know if it is possible to remove the borderline of the textbox that has been inserted in Excel chart. Yes, of course. This article focuses on delivering a solution to this issue.
In the following section, we're going to create two textboxes in the same chart, one textbox is built with borderline, the other one without. Then we can learn how to remove borderline using Spire.XLS by comparison.
Code snippet for remove borderline of textbox:
Step 1: Create a new instance of workbook.
Workbook workbook = new Workbook(); workbook.Version=ExcelVersion.Version2010;
Step 2: Create a new worksheet named "Remove Borderline" and add a chart to the worksheet.
Worksheet sheet = workbook.Worksheets[0]; sheet.Name = "Remove Borderline"; Chart chart = sheet.Charts.Add();
Step 3: Create textbox1 in the chart and input text information.
XlsTextBoxShape textbox1 = chart.TextBoxes.AddTextBox(50, 50, 100, 500) as XlsTextBoxShape;
Step 4: Create textbox2 in the chart, input text information and remove borderline.
XlsTextBoxShape textbox = chart.TextBoxes.AddTextBox(500, 50, 100, 500) as XlsTextBoxShape; textbox.Text = "The solution without borderline"; textbox.Line.Weight = 0;
Step 5: Save and launch the file.
workbook.SaveToFile("Sample.xlsx", ExcelVersion.Version2010);
Process.Start("Sample.xlsx");
Result:

sheet.Name = "Remove Borderline";
// Add a chart to the worksheet
Chart chart = sheet.Charts.Add();
// Add the first text box (with visible border)
XlsTextBoxShape textbox1 = chart.TextBoxes.AddTextBox(50, 50, 100, 500) as XlsTextBoxShape ;
textbox1.Text = "The original with borderline";
// Add the second text box (border will be hidden)
XlsTextBoxShape textbox2 = chart.TextBoxes.AddTextBox(500, 50, 100, 500) as XlsTextBoxShape;
textbox2.Text = "The solution without borderline";
// Hide the border by setting line weight to 0
textbox2.Line.Weight = 0;
// Save the result file
workbook.SaveToFile("Sample.xlsx", ExcelVersion.Version2010);
Process.Start("Sample.xlsx");

Various kinds of shapes like triangle, rectangle, ellipse, star, line and etc, can be created with Spire.Presentation. To make shapes more compatible with the entire slide, not only can we set color and choose fill style of the shape, we can also rotate shapes to a desired degree. This article is aimed to provide a simple example.
To begin with, create or open a .NET class application in Visual Studio 2005 or above versions, add Spire.Presentation.dll to your .NET project assemblies. Then, you are able create and format shapes using the sample C# code we have offered below.
Code snippets for rotate shapes on slide:
Step 1: Create an instance of Presentation class.
Presentation presentation = new Presentation();
Step 2: Add a new shape - Triangle ,to PPT slide.
IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Triangle, new RectangleF(100, 100, 100, 100));
Step 3: Rotate the shape to 180 degree.
shape.Rotation = 180;
Step 4: Set the color and fill style of shape.
shape.Fill.FillType = FillFormatType.Solid; shape.Fill.SolidColor.Color = Color.BlueViolet; shape.ShapeStyle.LineColor.Color = Color.Black;
Step 5: Save and launch the file.
presentation.SaveToFile("shape.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("shape.pptx");

This topic is just another request from one of our users on Spire.Doc Forum. In order to let more people know about this function, we’re going to present the whole procedure through a sample demo in the article. Additionally, we would like to remind you that we offer free customized demo for both pay users and test users.
As a professional .NET Word component, Spire.Doc enables developers to replace specified paragraph with a newly created table or an existing table. In this example, the paragraph 3 in main body of the sample word file will be replaced by a newly-built table.
Test file:
Code snippets for replacing text with table:
Step 1: Create a new word document and load the test file.
Document doc = new Document(); doc.LoadFromFile(@"..\..\test.docx");
Step 2: Return TextSection by finding the key text string "classical antiquity science".
Section section = doc.Sections[0];
TextSelection selection = doc.FindString("classical antiquity science", true, true);
Step 3: Return TextRange from TextSection, then get OwnerParagraph through TextRange.
TextRange range = selection.GetAsOneRange(); Paragraph paragraph = range.OwnerParagraph;
Step 4: Return the zero-based index of the specified paragraph.
Body body = paragraph.OwnerTextBody; int index = body.ChildObjects.IndexOf(paragraph);
Step 5: Create a new table.
Table table = section.AddTable(true); table.ResetCells(3, 3);
Step 6: Remove the paragraph and insert table into the collection at the specified index.
body.ChildObjects.Remove(paragraph); body.ChildObjects.Insert(index, table);
Step 7: Save and launch the file.
doc.SaveToFile("result.doc", FileFormat.Doc);
System.Diagnostics.Process.Start("result.doc");

Section section = doc.Sections[0];
TextSelection selection = doc.FindString("classical antiquity science", true, true);
TextRange range = selection.GetAsOneRange();
Paragraph paragraph = range.OwnerParagraph;
Body body = paragraph.OwnerTextBody;
int index = body.ChildObjects.IndexOf(paragraph);
Table table = section.AddTable(true);
table.ResetCells(3, 3);

Word bookmarks are widely used for point out a specified location or give brief information of the paragraph. If you add an image into the bookmark position, the bookmarks will be more obviously and clearly. This article will show you how to insert an image at bookmark position in C# with the help of Spire.Doc.
Spire.Doc offers an instance of BookmarksNavigator to find the bookmarks, and then developers use AppendPicture to add an image. Here comes to the steps:
Step 1: Load a word documents with bookmarks.
Document document = new Document();
document.LoadFromFile("Test.docx");
Step 2: Create an instance of BookmarksNavigator and find the bookmark where you want to insert an image.
//Create an instance of BookmarksNavigator
BookmarksNavigator bn = new BookmarksNavigator(document);
//Find a bookmark and its name is Spire
bn.MoveToBookmark("Spire", true, true);
Step 3: Insert an image at the position of bookmarks you found.
//Add a section and named it section0
Section section0 = document.AddSection();
//Add a paragraph for section0
Paragraph paragraph = section0.AddParagraph();
Image image = Image.FromFile("step.png");
//Add a picture into paragraph
DocPicture picture = paragraph.AppendPicture(image);
//Add a paragraph with picture at the position of bookmark
bn.InsertParagraph(paragraph);
document.Sections.Remove(section0);
Step 4: Save the new document and process it.
string output = "sample3.docx"; document.SaveToFile(output, FileFormat.Docx); System.Diagnostics.Process.Start(output);
Spire.Doc also offers the following properties to set the image position based on developers' requirements.
picture.TextWrappingStyle picture.HorizontalAlignment picture.HorizontalOrigin picture.HorizontalPosition picture.VerticalAlignment picture.VerticalOrigin picture.VerticalPosition

As is shown in the following presentation slide, shapes automatically stack in separate layers as you add them. To change the order of overlapping shapes, we can move the layers forward and backward. But how can we achieve this task programmatically using C# or VB.NET? This article is aimed to present you a solution on how to reorder overlapping shapes using Spire.Presentation.
In the early edition, Spire.Presentation is already capable of adding different kinds of shapes to the slides, setting color and fill style of the shape. In the Version2.0.18, we add reordering overlapping shapes as a new feature to satisfy our customer’s demands. Now, let’s see how to make it happen with sample code snippet.
Step 1: Create a new instance of Spire.Presentation class and load the test file.
Spire.Presentation.Presentation presentation = new Presentation();
presentation.LoadFromFile("..\\..\\test.pptx");
Step 2: Get the first shape from the slide.
IShape shape = presentation.Slides[0].Shapes[0];
Step 3: Change the shape's Zorder by setting its position index.
presentation.Slides[0].Shapes.ZOrder(1, shape);
Step 4: Save to a PPTX file and launch the file.
string output = "output.pptx"; presentation.SaveToFile(output,FileFormat.Pptx2010); System.Diagnostics.Process.Start(output);
Output:
Full code:
using Spire.Presentation;
namespace ReorderOverlappingShape
{
class Program
{
static void Main(string[] args)
{
//Create an instance of Spire.Presentation
Spire.Presentation.Presentation presentation = new Presentation();
//Load a pptx file
presentation.LoadFromFile("..\\..\\test.pptx");
//Get the first shape of the first slide
IShape shape = presentation.Slides[0].Shapes[0];
//Change the shape's zorder
presentation.Slides[0].Shapes.ZOrder(1, shape);
//Save to a pptx2010 file.
string output = "output.pptx";
presentation.SaveToFile(output, FileFormat.Pptx2010);
//Launch the output file
System.Diagnostics.Process.Start(output);
}
}

Everytime we try to open a password-protected PowerPoint file, we will then be prompted to enter the password. This can be really a bothering thing itself. But things get worse if we forget the password. To avoid this situation from being occurred, we can choose to remove the encryption if the PowerPoint file is not necessarily protected. In this article, I’ll introduce you how to remove encryption on password-protected PowerPoint file using Spire.Presentation.
In the classes of Spire.Presentation, you can invoke Presentation.LoadFromFile(string file, string password) method to load the file that you want to remove protection, then you're entitled to remove encryption by calling Presentation.RemoveEncryption() method. More details:
Step 1: Create Presentation instance and load file.
Presentation presentation = new Presentation();
presentation.LoadFromFile("Presentation1.pptx", "test");
Step 2: Remove encryption.
presentation.RemoveEncryption();
Step 3: Save and launch the file.
presentation.SaveToFile("result.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("result.pptx");

A table, as a great way to present data into groups, always plays an important role in any type of electronic documents. A well formatted table must contains larger or smaller cells without influencing the entire row or colum - and that's something that can be easily achieved by merging or splitting cells in your existing table.
In the next section, we will introduce you how to merge cells on en existing table which is embedded on a PowerPoint slide using Spire.Presentation for .NET. By convention, we need to download and install Spire.Presentation first, add its dll as a reference in you Visual C# or VB.NET project.
Assume you got a sample PPT file which contains a table like this, obviously you can merge cell 2 and cell 3 in the first column to display the account information more clearly.
How to achieve this programmatically using Spire.Presentation?
Step 1: Create a PPT document and load the sample file.
Presentation presentation = new Presentation();
presentation.LoadFromFile("table.pptx");
Step 2: Get the table and merge the second row and third row of the first column.
ITable table = null;
foreach (IShape shape in presentation.Slides[0].Shapes)
{
if (shape is ITable)
{
table = (ITable)shape;
table.MergeCells(table[0, 1], table[0, 2], false);
}
}
Step 3: Save and launch the file.
presentation.SaveToFile("result.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("result.pptx");

How to Expand/Collapse the rows in an existing Pivot Table in C#
2014-07-25 02:52:19 Written by AdministratorPivot table displays the data in sort, count total or give the average of the data stored in one table or spreadsheet. So it gives readers clear information of the data's trends and patterns rather than a large amount of similar data. Sometimes, there are so many rows in one pivot table and we may need to expand or collapse them to make the pivot table more clearly.
By using Spire.XLS for .NET, developers can create pivot table. This article will show you how to expand and collapse the rows in an existing Pivot table in C#.
Firstly, make sure that Spire.XLS for .NET (version7.5.5 or above) has been installed on your machine. And then, adds Spire.XLS.dll as reference in the downloaded Bin folder thought the below path: "..\Spire.XLS\Bin\NET4.0\ Spire.XLS.dll".
//Create a new excel document
Workbook book = new Workbook();
//load an excel document with Pivot table from the file
book.LoadFromFile("test.xlsx");
//Find the Pivot Table sheet
Worksheet sheet = book.Worksheets["Pivot Table"];
//Get the data in Pivot Table
Spire.Xls.Core.Spreadsheet.PivotTables.XlsPivotTable pivotTable = sheet.PivotTables[0] as Spire.Xls.Core.Spreadsheet.PivotTables.XlsPivotTable;
//Calculate Data
pivotTable.CalculateData();
//Collapse the rows
(pivotTable.PivotFields["Vendor No"] as Spire.Xls.Core.Spreadsheet.PivotTables.XlsPivotField).HideItemDetail("1501", true);
//Expand the rows
(pivotTable.PivotFields["Vendor No"] as Spire.Xls.Core.Spreadsheet.PivotTables.XlsPivotField).HideItemDetail("1502", false);
//Save the document to file
book.SaveToFile("result.xlsx", ExcelVersion.Version2007);

{
Image tiffImage = Image.FromFile(@"..\..\demo.tiff");
Image[] images = SplitTIFFImage(tiffImage);
for (int i = 0; i < images.Length; i++)
{
PdfImage pdfImg = PdfImage.FromImage(images[i]);
PdfPageBase page = pdfDocument.Pages.Add();
float width = pdfImg.Width * 0.5f;
float height = pdfImg.Height * 0.5f;
float x = (page.Canvas.ClientSize.Width - width) / 2;
//set the image of the page
page.Canvas.DrawImage(pdfImg, x, 0, width, height);
}
pdfDocument.SaveToFile(@"..\..\result.pdf");
System.Diagnostics.Process.Start(@"..\..\result.pdf");
}
}
public static Image[] SplitTIFFImage(Image tiffImage)
{
int frameCount = tiffImage.GetFrameCount(FrameDimension.Page);
Image[] images = new Image[frameCount];
Guid objGuid = tiffImage.FrameDimensionsList[0];
FrameDimension objDimension = new FrameDimension(objGuid);
for (int i = 0; i < frameCount; i++)
{
tiffImage.SelectActiveFrame(objDimension, i);
using (MemoryStream ms = new MemoryStream())
{
tiffImage.Save(ms, ImageFormat.Tiff);
images[i] = Image.FromStream(ms);
}
}
return images;
}
}
}
