richtextbox

My program reads a DDS image file and stores it as a byte array. I want to be able to show the users the raw data in a TextBox form so at first I convert the byte array to a string using the following code: string data = System.Text.Encoding.ASCII.GetString(bytes); I then set the TextBox text: textBox.Text = data; The problem I am having is the text box is not showing all the data. Here is a screenshot of how it looks: As you can see only the first few characters are displayed. I am assuming this is because the string contains a null terminator which the TextBox interprets as the end of the

I have some code in place currently to intercept all Cut, Copy and Paste events into a RichTextBox in WPF. These are designed to strip all content out except plain text, and allow no pasting except plain text (by using a check the Clipboard.ContainsText() method.) This seems to be successful at preventing all such operations from inside the forms. A user can only copy, cut and paste text around, with images / audio data / random junk not being allowed. However, if I use the PrintScreen function, and paste it into one of the RichTextBoxes, the image is pasted in (not the wanted behaviour.) If

How exactly do you change the Font in a RichTextBox? Looking around gives me old answers that doesn't seem to work any more. I thought it would be as simple as doing richtextbox1.Font = Font.Bold; or something similar. Turns out it's not, so I looked around. Apparently you have to change the FontStyle which is a readonly (??) property, but you have to do it making a new FontStyle Object. But even then that doesn't work o.o How do you do this? EDIT: Doesn't seem to work :\ rssTextBox.Document.Blocks.Clear(); rssTextBox.FontWeight = FontWeights.Bold; rssTextBox.AppendText("Title: "); rssTextBox

internal string Select(RichTextBox rtb, int index, int length) { TextRange textRange = new TextRange(rtb.Document.ContentStart, rtb.Document.ContentEnd); if (textRange.Text.Length >= (index + length)) { TextPointer start = textRange.Start.GetPositionAtOffset(index, LogicalDirection.Forward); TextPointer end = textRange.Start.GetPositionAtOffset(index + length, LogicalDirection.Backward); rtb.Selection.Select(start, end); rtb.Selection.ApplyPropertyValue(TextElement.BackgroundProperty, new SolidColorBrush(Colors.LightBlue)); } return rtb.Selection.Text; } whenever ApplyPropertyValue is called

How can I delete a specific line of text in a RichTextBox ? Another solution: private void DeleteLine(int a_line) { int start_index = richTextBox.GetFirstCharIndexFromLine(a_line); int count = richTextBox.Lines[a_line].Length; // Eat new line chars if (a_line < richTextBox.Lines.Length - 1) { count += richTextBox.GetFirstCharIndexFromLine(a_line + 1) - ((start_index + count - 1) + 1); } richTextBox.Text = richTextBox.Text.Remove(start_index, count); } This also could do the trick (if you can handle things such as ++ in forms code). Keeps the text format. Just remember "ReadOnly" attribute work

how can I update just one line text in richtextbox? String[] lines = richTextBox8.Lines; lines[2] += " "; richTextBox8.Lines = lines; I am using this code part for update second line of richtextbox but it scans all my richtextbox lines and it takes many times. so I want to update line text for 1 line. How can I do that? Note that you must never touch the Text or the Lines directly or all previous formatting gets messed up. Here is a function that will solve the problem without messing up the formatting: void changeLine(RichTextBox RTB, int line, string text) { int s1 = RTB
