I have a basic text editor app, and I aim to add a feature where the user can click a button and add premade text after where their cursor is.
I currently have this (using some code I found online)
richTextBox1.CaretPosition.InsertTextInRun(s);
I intend for the string s to be the string to be added.
However, the RichTextBox in System.Windows.Forms does NOT contain a CaretPosition. I found one post from 2010 suggesting you use System.Windows.Control, however, that is no longer accessible in .Net Core, it depends on presentation framework.
So, is there any way I could get my goal (inserting a string after the mouse cursor, in a rich text box), in .net core?
Updated2:
Use the following code to fully satisfy the richtextbox of the text text environment.:
richTextBox1.Select(richTextBox1.SelectionStart, richTextBox1.TextLength);//Select everything after the cursor
string tmp = richTextBox1.SelectedText;//Copy them
richTextBox1.SelectedText = "";//Set to null
richTextBox1.AppendText("Hello world"+tmp);//Add the target string and add the original text
Updated1:
// Determine if there is any text in the Clipboard to paste into the text box.
if (Clipboard.GetDataObject().GetDataPresent(DataFormats.Text) == true)
{
IDataObject dataObject = Clipboard.GetDataObject();
Clipboard.SetDataObject("Hello World");
richTextBox1.Paste();
Clipboard.SetDataObject(dataObject);
}
else
{
Clipboard.SetDataObject("Hello World");
richTextBox1.Paste();
}
This action preserves the contents of the original pasteboard.
Only works if the clipboard is data. I will continue to update after I think about it.
Original:
You only need to use the clipboard and paste method to insert the specified string after the specified cursor.
Clipboard.SetDataObject("Hello World");
richTextBox1.Paste();
Clipboard.Clear();
Change it yourself according to your needs.
I know that this question may be very old and classic but, I am trying to find a free and good word editor control to be embedded into my application for educational purpose, so I googled and tried a lot of editors and methods like using RichTextBox control and fill the RTF value with my word document data and it was displayed into the RichTextBox but without any editing capabilities that exist in the real Word application.
I just need some of the editing capabilities that are exist in the word not all of them, so I decided to build my own word editor but actually I can't find a good way to start that and I don't have that experience, Any Ideas?
What I did until now is very basic and I need to know for example how to add a new method to attach word document to my editor so I need to do something like
wordEditor1.Word = {Path of word document}
and this step should show the document inside my editor with all styles and formats just like opening any word document inside word application.
Also I need to add capability of applying paragraph style or character style on the selected paragraph, so I think that I need to add methods for characters or paragraphs like
selectedParagraph.Style = {name of style in word or name of selected style form styles pane}
Finally I need to allow user to run macros on the opened document and I know that this may be the hardest step, so I just need some ideas to redirect me to the best way of how to do that.
What I did till now is something like
using System.Windows.Forms;
namespace AutoStyle
{
public partial class WordEditor : RichTextBox
{
public WordEditor()
{
InitializeComponent();
}
public object Word
{
get;
set;
}
protected override void OnPaint(PaintEventArgs pe)
{
base.OnPaint(pe);
}
}
}
I believe that this question may help others like me who is newbie and has a lack of experience, so I appreciate you comments and efforts.
I've used WindowsApiCodePack C# wrapper of windows TaskDialogs.
When I tried to show long text with paths, I got all my paths shortened by ellipsis instead of true word-wrap. This makes filenames in paths non-readable. Like here:
Same behavior when settings this text in spolier text or in main text.
Is the way to disable this feature? I want my paths to be shown completely, wrapped or somehow else.
This is what I expect from text. How MessageBox work with text:
I have a small windows application that has a series of labels on it. This application will be globalized and there is a possibility that the text on these labels might get truncated. I am trying to automate to identify truncated text on these labels.
For other controls, I can use TextPattern.Pattern through which I can find the visible text and the actual text inside the control. But for the labels (ControlType.text) the TextPattern is not supported. How do I find the visible text for these lables using UI automation.
Here is the code I tried. If I pass control type as Document it works. But with Text control type it gives a unsupported pattern exception.
private String TextFromSelection(AutomationElement target, Int32 length)
{
// Specify the control type we're looking for, in this case 'Document'
PropertyCondition cond = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Text);
// target --> The root AutomationElement.
AutomationElement textProvider = target.FindFirst(TreeScope.Descendants, cond);
TextPattern textpatternPattern = textProvider.GetCurrentPattern(TextPattern.Pattern) as TextPattern;
if (textpatternPattern == null)
{
Console.WriteLine("Root element does not contain a descendant that supports TextPattern.");
return null;
}
var test = textpatternPattern.DocumentRange.GetText(-1).TrimEnd('\r');
var tpr = textpatternPattern.GetVisibleRanges();
var txt = tpr[0].GetText(-1);
return txt;
}
Whether the text pattern is supported by the label element will be affected by which UI framework is being used. For example, the labels in the Win32 Run dlg don't support the Text pattern, but labels in the Windows 10 XAML Calculator do. The image below shows the Inspect SDK tool reporting that the Text pattern is supported by the "There's no history yet" label.
It's important to note that whether the UI framework (or the app if the app implements the UIA Text pattern directly) includes the truncated text in the data it returns to you when you call IUIAutomationTextPattern::GetVisibleRanges(), is up to the framework (or app) itself. For example, WordPad running on Windows 10 doesn't include the text that's clipped out of view, but Word 2013 does return the clipped text.
Thanks,
Guy
You should be able to simply use element.Current.Name (element being the instance of AutomationElement for the label).
Here is an example of UISpy retrieving the text for a label:

Why isn’t the richtextbox displaying this table properly?
We are having problems with the Windows.Forms.RichTextBox control in Visual Studio 2008.
We are trying to display text supplied as an RTF file by a 3rd party in a windows forms application (.NET 3.5). In this RTF text file there are tables, which contain text that spans multiple lines. The RTF file displays correctly when opened with either WordPad or Word 2003.
However, when we load the RTF file into the RichTextBox control, or copy & paste the whole text (including the table) into the control, the table does not display correctly - the cells are only single line, without wrapping.
Here are links to images showing the exact problem:
Correctly displayed in WordPad
Incorrectly displayed in RichTextBox control
I have googled for solutions and 3rd party .net RTF controls without success. I have found this exact problem asked on another forum without an answer (in fact that's where the link to the images come from) so I'm hoping stack overflow does better ;-)
My preferred solution would be to use code or a 3rd party control that can correctly render the RTF. However, I suspect the problem is that the RichTextBox control only supports a subset of the full RTF spec, so another option would be to modify the RTF directly to remove the unsupported control codes or otherwise fix the RTF file itself (in which case any information as to what control codes need to be removed or modified would be a huge help).
The Rich Text box from .NET is extremely buggy.
In RTF, the way a table is defined is actually quite different from what you could expect if you are used to HTML.
HTML:
<table>
<tr>
<td>Mycell</td>
</tr>
</table>
In RTF, a table is simply a series of paragraphs with control words defining rows, cells, borders. There is no group tag for the start/end of a table.
RTF:
\trowd\trgraph \cellx1000 Mycell \cell\row\pard\par
If you want to add a paragraph inside a cell, you use \par and the control \intbl (in table) to indicate the paragraph is inside the table.
.NET RTB can handle only a very small subset of RTF control words and doesn't support the vast majority of available commands. By the looks of things, \intbl is part of the long long list of control words it doesn't support, and if it actually parses \par at that point, the display is trashed.
Unfortunately, I don't have a solution for that but I hope the small explanation above helps you make some sense of the problem.
Don't put too much faith on my RTF sample. It works, but it's absolutely bare-bones. You can download the RTF specifications from Microsoft's website:
Word 2007 RTF specs.
Can you use the old COM control instead of the new .NET control, or do you require a "pure" .NET solution?
In other words, go into the Visual Studio toolbox, right click, choose "Choose Items", look in the COM Components tab and check Microsoft Rich Textbox Control 6.0.
Answering my own question here, but only due to the help from Joel and sylverdrag...
The short answer is that both the .Net and underlying COM RichTextBox do not support word wrap in tables. I ended up knocking up a test application and using both the COM and .Net RichTextBox controls and they both exhibited the same (broken) behaviour.
I also downloaded the RTF spec from the link supplied by sylverdrag and after tinkering with hand-made RTF documents in MS Word and RichTextEdit controls, I can confirm that TichTextBox does not correctly support the \intbl control word - which is required for word wrap in tables.
There appear to be three possible solutions:
Use TX Text Control. I have confirmed this works using a trial version but it is expensive - prices start at US$549 per developer.
Use an embedded MS Word instance as discussed on Code Project. Note that the code example provided on Code Project didn't work out of the box but I did get it working with Office 2003 & VS 2008. After much mucking around we hit an unexpected show stopper - we want the document to be read-only so we Protect() the document. While this works, when a user tries to edit the document the MS Word "Protect Document" side bar pops out from the right hand side of the control. We can't live with this and I was not able to turn it off (and from googling it looks like I'm not alone).
Give up on RTF and use HTML instead and then render the document in a WebBrowser control instead of a RichTextEdit control. That is the option we are taking as it turns out the source document is available in either format.
Step 1, Use the old COM Microsoft Rich Textbox Control 6.0;
Step 2, Make a copy of Windows\System32\MsftEdit.dll and then rename it to riched20.dll;
Step 3, Copy riched20.dll to your app folder such as bin\bebug.
This works fine, table displays correctly.
Wordpad is generally a very thin wrapper over the rich edit control, so if it appears properly there then Windows should be able to handle it.
Perhaps you're instantiating the wrong version of the rich edit control? There have been many, and Windows continues to supply the older ones for backwards compatibility. http://msdn.microsoft.com/en-us/library/bb787873(VS.85).aspx
Just create a new Control. It works fine for me.
using System;
using System.ComponentModel;
using System.Windows.Forms;
using System.Runtime.InteropServices;
public class RichTextBox5 : RichTextBox {
private static IntPtr moduleHandle;
protected override CreateParams CreateParams {
get {
if (moduleHandle == IntPtr.Zero) {
moduleHandle = LoadLibrary("msftedit.dll");
if ((long)moduleHandle < 0x20) throw new Win32Exception(Marshal.GetLastWin32Error(), "Could not load Msftedit.dll");
}
CreateParams createParams = base.CreateParams;
createParams.ClassName = "RichEdit50W";
if (this.Multiline) {
if (((this.ScrollBars & RichTextBoxScrollBars.Horizontal) != RichTextBoxScrollBars.None) && !base.WordWrap) {
createParams.Style |= 0x100000;
if ((this.ScrollBars & ((RichTextBoxScrollBars)0x10)) != RichTextBoxScrollBars.None) {
createParams.Style |= 0x2000;
}
}
if ((this.ScrollBars & RichTextBoxScrollBars.Vertical) != RichTextBoxScrollBars.None) {
createParams.Style |= 0x200000;
if ((this.ScrollBars & ((RichTextBoxScrollBars)0x10)) != RichTextBoxScrollBars.None) {
createParams.Style |= 0x2000;
}
}
}
if ((BorderStyle.FixedSingle == base.BorderStyle) && ((createParams.Style & 0x800000) != 0)) {
createParams.Style &= -8388609;
createParams.ExStyle |= 0x200;
}
return createParams;
}
}
// P/Invoke declarations
[DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Auto)]
private static extern IntPtr LoadLibrary(string path);
}
This is not a issue of RitchText Control provided in .net . some Ritchtext rules (Ritchtext Synatax) has been changed in new version of Ms-office (2007). however the component used in .net cannot update to cater the new rules so the issue occours.
