问题 I'm creating a dictionary system, where words meaning is editable in RichTextBox (for user define FontSize, Color, etc...) So how to can I save meaning RichTextBox content in the Access database in RTF format? And how to can I read this? 回答1: Native Rich text in Access 2007/2010/2013 uses a subset of HTML, not RTF, so unless you want to convert to/from RTF<>HTML when you load/save your data, you will have to find another way to store your formatted text. Since the WPF RichText control uses

问题 I'd like an input field that I can have javascript set certain attributes for, for different parts of the input field. A simple example to demonstrate what I'd like to do: let's say I want to underline all curse words in an input text area. So the javascript would check the input text area when a new letter is inserted, and for any words matching my array of recognized curse words, it would underline the word. Note, I do not want the user/client to be able to set any attributes of the text, I

问题 How to check if selected text on richtextbox is all bold. For example: asdasd asd asd ← this is not all bold Im all bold ← this is all bold This is the code I have made, it can check if its all bold or not but its slow because its checking the char one by one using Selection.Start to Selection.Length and check if bold. bool allbold = true; int start = richTextBox1.SelectionStart; int end = richTextBox1.SelectionLength; for (int i = 1; i < end; i++) { richTextBox1.SelectionStart = start+i;

问题 I'm trying to implement the Application.Find command for the WPF richtextbox. Let's say I'm searching for "expert". Sounds easy enough. But due to the nature of wpf, if every other letter in "expert" is bolded, then the richtextbox contains e* x *p* e *r* t * and that means six runs exist. I have a starting textPointer. What I'm trying to figure out is how to get the ending textPointer so that I can create a TextRange that I can use to create the Selection. In this example, the starting

问题 I saw how to set a WPF rich text box in RichTextBox Class . Yet I like to save its text to the database like I used to, in Windows Forms. string myData = richTextBox.Text; dbSave(myData); How can I do it? 回答1: At the bottom of the MSDN RichTextBox reference there's a link to How to Extract the Text Content from a RichTextBox It's going to look like this: public string RichTextBoxExample() { RichTextBox myRichTextBox = new RichTextBox(); // Create a FlowDocument to contain content for the

问题 Editing a RichTextBox control's text (more specifically, modifying selection font/color) programmatically seems to be tracked in the control's built in undo stack. Is there a way, short of writing my own undo/redo "manager", to prevent certain actions/operations from being added to the undo stack ? 回答1: No cando. At best you can flush the undo stack completely by sending EM_SETUNDOLIMIT twice. EM_SETTEXTEX offers the same option with the ST_DEFAULT flag. Surely not what you want. Look at

问题 I can extend the ToolTip and create my own RichToolTip but I don't understand how I can handle formatting per line or Per word.

Any suggestions? Are there any open source components which I can use? public class RichToolTip : ToolTip { public RichToolTip() { this.OwnerDraw = true; this.Draw += new
