How to set ContentControl.Range to the current ContentControl I am working from?

I am not finding a way to set the ContentControl.Range.Text from where the C# is executing from (inside the content control). Perhaps I should be looking at it from a completely different perspective.
Currently I have a content control that produces a set of text with some text between [] square brackets and I want to select text and format the colour by setting the start and end of the range of characters between the []. I am stuck on trying to set the initial range to the contentcontrol I am currently using.
Most of what I have managed/found/patched together below.
object word;
Microsoft.Office.Interop.Word.Document _PWdDoc;
try
{
word = System.Runtime.InteropServices.Marshal.GetActiveObject("Word.Application");
//If there is a running Word instance, it gets saved into the word variable
}
catch (Exception ex)
{
//If there is no running instance, it creates a new one
Type type = Type.GetTypeFromProgID("Word.Application");
word = System.Activator.CreateInstance(type);
}
Microsoft.Office.Interop.Word.Application oWord = (Microsoft.Office.Interop.Word.Application) word;
_PWdDoc = oWord.ActiveDocument;
System.Collections.IEnumerator ContentX = _PWdDoc.ContentControls.GetEnumerator();
//Microsoft.Office.Interop.Word.ContentControl ContentX = Microsoft.Office.Interop.Word.ContentControls.Item[];
//Microsoft.Office.Interop.Word.Range rng = Microsoft.Office.Interop.Word.ContentControl.Range.Duplicate(ref ContentX);
//var rngX = Microsoft.Office.Interop.Word.ContentControl.Range(ContentX);
//Microsoft.Office.Interop.Word.ContentControl cc1 = ContentX;
Excuse the coding mess but it's all I can come up with with the minimal experience I have with this.
Now I have gotten the IEnumerator fo the Content Control(I think) I have no idea how to use it besides from what I have read, they say to iterate through the IEnumerables accessing each of them. That's not what I want to do. I want 1 content control. The current one that I am working in. I want to find it's range and assign it to a value. Then in that range's "text" I want to do some [fancy] highlighting.

Determining whether the current selection or a specific Range is in a content control and doing something with that content control is not a trivial matter. Most other Word objects will return something that they're "in"; content controls do not.
So the approach I use is to
create a Range that reaches from the current selection (or a specific Range) back to the beginning of the document
count the number of content controls in that range
then check whether the current selection is in the same range as the last content control of the extended range.
if it is, then I know the selection is within a content control and I can access the content control.
Here's some sample code. The snippet that calls the function I use to return the information:
Word.Range rng = null;
//Substitute a specific Range object if working with a Range, rather than a Selection
Word.ContentControl cc = IsSelectionInCC(wdApp.Selection.Range);
if ( cc != null)
{
rng = cc.Range;
rng.HighlightColorIndex = Word.WdColorIndex.wdYellow;
}
The function:
private Word.ContentControl IsSelectionInCC(Word.Range sel)
{
Word.Range rng = sel.Range;
Word.Document doc = (Word.Document) rng.Parent;
rng.Start = doc.Content.Start;
int nrCC = rng.ContentControls.Count;
Word.ContentControl cc = null;
bool InCC = false;
rng.Start = doc.Content.Start;
if (nrCC > 0)
{
if (sel.InRange(doc.ContentControls[nrCC].Range))
{
InCC = true; //Debug.Print ("Sel in cc")
cc = doc.ContentControls[nrCC];
}
else
{
sel.MoveEnd(Word.WdUnits.wdCharacter, 1);
if (sel.Text == null)
{
//Debug.Print ("Sel at end of cc")
InCC = true;
cc = doc.ContentControls[nrCC];
}
}
}
return cc;
}

Assuming you mean that the insertion point is inside a Content Control, and your Word Application object is called oWord, then you can get the range of that content control using e.g.
Microsoft.Office.Interop.Word.Range r = oWord.Selection.Range.ParentContentControl.Range
If you have nested controls You can verify that the insertion point is in a Content Control (Word 2013 and later, I think) by checking the value of inCC as follows:
Boolean inCC = (Boolean)oWord.Selection.Information[Microsoft.Office.Interop.Word.WdInformation.wdInContentControl]
However, when dealing with content controls, be aware that selecting a content control in the UI is different from selecting the "range of the content control". Programmatically, it's obvious how to select the Range - not so obvious how to select the control. If you select the Range, the ParentContentControl should be the control whose range you've selected. If you (or the user) selected the control, OTTOMH I am not so sure.

Adding header to pages using iText7

I need to add an HTML block as the header of all pages using iText7. The header contains an image logo and some text.
I have this at the moment, before closing the document object:
for (int i = 1; i <= n; i++)
{
float x = pdf.GetPage(i).GetPageSize().GetWidth() / 2; // 297.5f
float yFooter = 20;
if (headerBlock != null)
{
float yHeader = 600;// pdf.GetPage(i).GetPageSize().GetTop() - 20;
// Header
document.ShowTextAligned(headerBlock, 0, yHeader, page, TextAlignment.LEFT, VerticalAlignment.BOTTOM, 0);
}
// Footer
Paragraph footerBlock = new Paragraph(String.Format("Página {0} de {1}", i, n));
document.ShowTextAligned(footerBlock, x, yFooter, page, TextAlignment.CENTER, VerticalAlignment.MIDDLE, 0);
}
Footer works correctly but header.
Header was loaded this way:
Paragraph headerBlock = String.IsNullOrWhiteSpace(header) ? null : CreateHtmlParagraph(header);
where, CreateHtmlParagraph is defined this way:
private Paragraph CreateHtmlParagraph(string html)
{
Paragraph p = new Paragraph();
ConverterProperties properties = new ConverterProperties();
properties.SetBaseUri(HttpContext.Current.Server.MapPath("/"));
var elements = HtmlConverter.ConvertToElements(html, properties);
foreach (IElement e in elements)
p.Add((IBlockElement)e);
return p;
}
When I add the header using the document.Add method, it works well, but for the first page only. All other content follows it.
When I try to add it using ShowTextAligned method, only the image is rendered in all pages.
By the way, is there a way to get the actual height of the header paragraph? I think, once the header positioning is solved, I will have the problem that the other content blocks will be overlapped by the header.

I believe you need to use page events. This is well documented. Create a class that implements IEventHandler that will handle specific events.
Add a event handler for a specific event
pdf.AddEventHandler(PdfDocumentEvent.START_PAGE, new StartPageEventHandler());
StartPageEventHandler is a class you create, implementing IEventHandler. You'll likely need to take this approach for both header and footer.

Way to format Form with dynamic text fields c#

Right, so I have 13 textboxes with corresponding labels that are assigned after a user decides the name from a different form (instantiated by the 'Add field...' button). The issue arises when the user wishes to delete a textbox with previously entered data, as this results in an empty space where the textbox and label originally were as visualized by the following image:
My question is: how do I make it so that when a user chooses to delete a textbox, the textbox-label pair(s) that follow it replace the deleted textbox AND shift the remaining textboxes accordingly.
Textbox-label pairs in designer:
I've thought about this problem intensively over the past few days, and have concluded that with my current knowledge of C# I am limited to solving this issue with a horrendously tedious amount of if-statements (talking hundreds - thousands here). Any and all help would be appreciated!
Current code on the X-button for first textbox-label pair:
private void xButton1_Click(object sender, EventArgs e)
{
label14.Text = "";
textBox1.Text = "";
if (label14.Text.Equals(""))
{
label14.Visible = false;
textBox1.Visible = false;
xButton.Visible = false;
label14.Text = "";
textBox1.Text = "";
}
if (!textBox2.Text.Equals(""))
{
label14.Text = label15.Text;
textBox1.Text = textBox2.Text;
}
if (!textBox2.Text.Equals("") && (textBox3.Text.Equals("")))
{
label15.Visible = false;
textBox2.Text = "";
textBox2.Visible = false;
xButton2.Visible = false;
}
}

One simple thing you could do is give all your "dynamic" controls (label, textbox, button) a similar value in their Tag property (in my example, I used the string "dynamic" for all the control Tags. This enables you to query for them easily.
Next, you could follow the logic that, anytime you delete some controls, you move all controls below the deleted ones up a distance equal to the height of the control being deleted plus whatever padding you have between the controls.
For example, when a user clicks the X button, since you know the value of the Bottom of the control that's being deleted, you could find all controls that had a matching Tag property whose Top is greater than the x button Bottom, and you can move them up.
Here's an example (this assumes that all your X buttons are mapped to this same click event):
private void buttonX_Click(object sender, EventArgs e)
{
// This is represents the distance between the bottom
// of one control to the top of the next control
// Normally it would be defined globally, and used when you
// lay out your controls.
const int controlPadding = 6;
var xButton = sender as Button;
if (xButton == null) return;
var minTopValue = xButton.Bottom;
var distanceToMoveUp = xButton.Height + controlPadding;
// Find all controls that have the Tag and are at the same height as the button
var controlsToDelete = Controls.Cast<Control>().Where(control =>
control.Tag != null &&
control.Tag.ToString() == "dynamic" &&
control.Top == xButton.Top)
.ToList();
// Delete the controls
controlsToDelete.ForEach(Controls.Remove);
// Get all controls with the same tag that are below the deleted controls
var controlsToMove = Controls.Cast<Control>().Where(control =>
control.Tag != null &&
control.Tag.ToString() == "dynamic" &&
control.Top > minTopValue);
// Move each control up the specified amount
foreach (var controlToMove in controlsToMove)
{
controlToMove.Top -= distanceToMoveUp;
}
}

Create spacing between checkboxes

I'm auto generating checkboxes and putting them into a panel,but when I do that, they all appear at the same point. I can manually move them apart, but this could cause problems down the line. Is there a way to get them to automatically align under each other.
Here's my code:
foreach (Category i in DesktopApp.getBaseCat())
{
checkBox = new CatBox();
checkBox.setCat(i);
checkBox.Text = i.ToString(); // puts the name of the category in the text field
checkBox.Click += new EventHandler(simpleCatBox_Click);
this.categoryPanel.Controls.Add(checkBox); // adds it to the panel
step++; // increments step
}

Give the checkbox a margin (10px in this example)
checkBox.Margin = new Thinkness(10);
Or, if you want different margins
checkBox.Margin = new Thickness(left,top,right,bottom);

How to Reading hyperlinks with AnchorText from pdf file C#

I have taken the link values from PDF file like http://google.com
but I need to take the anchor text value, for example click here.
How to to take the anchor link value text?
I have taken the URL value of the PDF file by using the below URL: Reading hyperlinks from pdf file
for example.
Anchor a = new Anchor("Test Anchor");
a.Reference = "http://www.google.com";
myParagraph.Add(a);
Here I get the http://www.google.com but I need to get anchor value i.e. Test Anchor
Need your suggestions.

From the PDF file you need to identify the region where the link is placed and then read the text below the link using iTextSharp.
This way you can extract the text underneath the link. The limitation of this approach is that if the link region is wider than the text, the extraction will read the full text under that region.
private void GetAllHyperlinksFromPDFDocument(string pdfFilePath)
{
string linkTextBuilder = "";
string linkReferenceBuilder = "";
PdfDictionary PageDictionary = default(PdfDictionary);
PdfArray Annots = default(PdfArray);
PdfReader R = new PdfReader(pdfFilePath);
List<BinaryHyperlink> ret = new List<BinaryHyperlink>();
//Loop through each page
for (int i = 1; i <= R.NumberOfPages; i++)
{
//Get the current page
PageDictionary = R.GetPageN(i);
//Get all of the annotations for the current page
Annots = PageDictionary.GetAsArray(PdfName.ANNOTS);
//Make sure we have something
if ((Annots == null) || (Annots.Length == 0))
continue;
//Loop through each annotation
foreach (PdfObject A in Annots.ArrayList)
{
//Convert the itext-specific object as a generic PDF object
PdfDictionary AnnotationDictionary = (PdfDictionary)PdfReader.GetPdfObject(A);
//Make sure this annotation has a link
if (!AnnotationDictionary.Get(PdfName.SUBTYPE).Equals(PdfName.LINK))
continue;
//Make sure this annotation has an ACTION
if (AnnotationDictionary.Get(PdfName.A) == null)
continue;
//Get the ACTION for the current annotation
PdfDictionary AnnotationAction = (PdfDictionary)AnnotationDictionary.GetAsDict(PdfName.A);
if (AnnotationAction.Get(PdfName.S).Equals(PdfName.URI))
{
//Get action link URL : linkReferenceBuilder
PdfString Link = AnnotationAction.GetAsString(PdfName.URI);
if (Link != null)
linkReferenceBuilder = Link.ToString();
//Get action link text : linkTextBuilder
var LinkLocation = AnnotationDictionary.GetAsArray(PdfName.RECT);
List<string> linestringlist = new List<string>();
iTextSharp.text.Rectangle rect = new iTextSharp.text.Rectangle(((PdfNumber)LinkLocation[0]).FloatValue, ((PdfNumber)LinkLocation[1]).FloatValue, ((PdfNumber)LinkLocation[2]).FloatValue, ((PdfNumber)LinkLocation[3]).FloatValue);
RenderFilter[] renderFilter = new RenderFilter[1];
renderFilter[0] = new RegionTextRenderFilter(rect);
ITextExtractionStrategy textExtractionStrategy = new FilteredTextRenderListener(new LocationTextExtractionStrategy(), renderFilter);
linkTextBuilder = PdfTextExtractor.GetTextFromPage(R, i, textExtractionStrategy).Trim();
}
}
}
}

Unfortunately I don't think you're going to be able to do this, at least not without a lot of guess-work. In HTML this would be easy because a hyperlink and its text are stored together as:
Click here
However, in a PDF these two entities are not stored with any form of relationship. What we think of as a "hyperlink" within a PDF is technically a PDF Annotation that just happens to be sitting on top of text. You can see this by opening a PDF in an editing program such as Adobe Acrobat Pro. You can change the text but the "clickable" area doesn't change. You can also move and resize the "clickable" area and put it anywhere in the document.
When creating PDFs, iText/iTextSharp abstract this away so you don't have to think about this. You can create a "hyperlink" with clickable text but when it generates a PDF it ultimately will create the text as normal text, calculate the rectangle coordinates and then put an annotation at that rectangle.
I did say that you could try to guess at this, and it might or might not work for you. To do this you'd need to get the rectangle for annotation and then find the text that's also at those coordinates. It won't be an exact match, however, because of padding issues. If you absolutely have to get the text under a hyperlink then this is the only way that I know of for doing this. Good luck!
