I'm trying to color parts of a string to be appended to a RichTextBox. I have a string built from different strings.
string temp = "[" + DateTime.Now.ToShortTimeString() + "] " +
userid + " " + message + Environment.NewLine;
This is what the message would look like once it is constructed.
[9:23pm] User: my message here.
I want everything within and including the brackets [9:23] to be one color, 'user' to be another color and the message to be another color. Then I'd like the string appended to my RichTextBox.
How can I accomplish this?
Here is an extension method that overloads the AppendText method with a color parameter:
public static class RichTextBoxExtensions
{
public static void AppendText(this RichTextBox box, string text, Color color)
{
box.SelectionStart = box.TextLength;
box.SelectionLength = 0;
box.SelectionColor = color;
box.AppendText(text);
box.SelectionColor = box.ForeColor;
}
}
And this is how you would use it:
var userid = "USER0001";
var message = "Access denied";
var box = new RichTextBox
{
Dock = DockStyle.Fill,
Font = new Font("Courier New", 10)
};
box.AppendText("[" + DateTime.Now.ToShortTimeString() + "]", Color.Red);
box.AppendText(" ");
box.AppendText(userid, Color.Green);
box.AppendText(": ");
box.AppendText(message, Color.Blue);
box.AppendText(Environment.NewLine);
new Form {Controls = {box}}.ShowDialog();
Note that you may notice some flickering if you're outputting a lot of messages. See this C# Corner article for ideas on how to reduce RichTextBox flicker.
I have expanded the method with font as a parameter:
public static void AppendText(this RichTextBox box, string text, Color color, Font font)
{
box.SelectionStart = box.TextLength;
box.SelectionLength = 0;
box.SelectionColor = color;
box.SelectionFont = font;
box.AppendText(text);
box.SelectionColor = box.ForeColor;
}
This is the modified version that I put in my code (I'm using .Net 4.5) but I think it should work on 4.0 too.
public void AppendText(string text, Color color, bool addNewLine = false)
{
box.SuspendLayout();
box.SelectionColor = color;
box.AppendText(addNewLine
? $"{text}{Environment.NewLine}"
: text);
box.ScrollToCaret();
box.ResumeLayout();
}
Differences with original one:
Possibility to add text to a new line or simply append it
No need to change selection, it works the same
Inserted ScrollToCaret to force autoscroll
Added SuspendLayout/ResumeLayout calls for better performance
EDIT : sorry this is a WPF answer
I think modifying a "selected text" in a RichTextBox isn't the right way to add colored text.
So here a method to add a "color block" :
Run run = new Run("This is my text");
run.Foreground = new SolidColorBrush(Colors.Red); // My Color
Paragraph paragraph = new Paragraph(run);
MyRichTextBlock.Document.Blocks.Add(paragraph);
From MSDN :
The Blocks property is the content property of RichTextBox. It is a
collection of Paragraph elements. Content in each Paragraph element
can contain the following elements:
Inline
InlineUIContainer
Run
Span
Bold
Hyperlink
Italic
Underline
LineBreak
So I think you have to split your string depending on parts color, and create as many Run objects as needed.
It`s work for me! I hope it will be useful to you!
public static RichTextBox RichTextBoxChangeWordColor(ref RichTextBox rtb, string startWord, string endWord, Color color)
{
rtb.SuspendLayout();
Point scroll = rtb.AutoScrollOffset;
int slct = rtb.SelectionIndent;
int ss = rtb.SelectionStart;
List<Point> ls = GetAllWordsIndecesBetween(rtb.Text, startWord, endWord, true);
foreach (var item in ls)
{
rtb.SelectionStart = item.X;
rtb.SelectionLength = item.Y - item.X;
rtb.SelectionColor = color;
}
rtb.SelectionStart = ss;
rtb.SelectionIndent = slct;
rtb.AutoScrollOffset = scroll;
rtb.ResumeLayout(true);
return rtb;
}
public static List<Point> GetAllWordsIndecesBetween(string intoText, string fromThis, string toThis,bool withSigns = true)
{
List<Point> result = new List<Point>();
Stack<int> stack = new Stack<int>();
bool start = false;
for (int i = 0; i < intoText.Length; i++)
{
string ssubstr = intoText.Substring(i);
if (ssubstr.StartsWith(fromThis) && ((fromThis == toThis && !start) || !ssubstr.StartsWith(toThis)))
{
if (!withSigns) i += fromThis.Length;
start = true;
stack.Push(i);
}
else if (ssubstr.StartsWith(toThis) )
{
if (withSigns) i += toThis.Length;
start = false;
if (stack.Count > 0)
{
int startindex = stack.Pop();
result.Add(new Point(startindex,i));
}
}
}
return result;
}
Selecting text as said from somebody, may the selection appear momentarily.
In Windows Forms applications there is no other solutions for the problem, but today I found a bad, working, way to solve: you can put a PictureBox in overlapping to the RichtextBox with the screenshot of if, during the selection and the changing color or font, making it after reappear all, when the operation is complete.
Code is here...
//The PictureBox has to be invisible before this, at creation
//tb variable is your RichTextBox
//inputPreview variable is your PictureBox
using (Graphics g = inputPreview.CreateGraphics())
{
Point loc = tb.PointToScreen(new Point(0, 0));
g.CopyFromScreen(loc, loc, tb.Size);
Point pt = tb.GetPositionFromCharIndex(tb.TextLength);
g.FillRectangle(new SolidBrush(Color.Red), new Rectangle(pt.X, 0, 100, tb.Height));
}
inputPreview.Invalidate();
inputPreview.Show();
//Your code here (example: tb.Select(...); tb.SelectionColor = ...;)
inputPreview.Hide();
Better is to use WPF; this solution isn't perfect, but for Winform it works.
I created this Function after researching on the internet since I wanted to print an XML string when you select a row from a data grid view.
static void HighlightPhrase(RichTextBox box, string StartTag, string EndTag, string ControlTag, Color color1, Color color2)
{
int pos = box.SelectionStart;
string s = box.Text;
for (int ix = 0; ; )
{
int jx = s.IndexOf(StartTag, ix, StringComparison.CurrentCultureIgnoreCase);
if (jx < 0) break;
int ex = s.IndexOf(EndTag, ix, StringComparison.CurrentCultureIgnoreCase);
box.SelectionStart = jx;
box.SelectionLength = ex - jx + 1;
box.SelectionColor = color1;
int bx = s.IndexOf(ControlTag, ix, StringComparison.CurrentCultureIgnoreCase);
int bxtest = s.IndexOf(StartTag, (ex + 1), StringComparison.CurrentCultureIgnoreCase);
if (bx == bxtest)
{
box.SelectionStart = ex + 1;
box.SelectionLength = bx - ex + 1;
box.SelectionColor = color2;
}
ix = ex + 1;
}
box.SelectionStart = pos;
box.SelectionLength = 0;
}
and this is how you call it
HighlightPhrase(richTextBox1, "<", ">","</", Color.Red, Color.Black);
private void Log(string s , Color? c = null)
{
richTextBox.SelectionStart = richTextBox.TextLength;
richTextBox.SelectionLength = 0;
richTextBox.SelectionColor = c ?? Color.Black;
richTextBox.AppendText((richTextBox.Lines.Count() == 0 ? "" : Environment.NewLine) + DateTime.Now + "\t" + s);
richTextBox.SelectionColor = Color.Black;
}
Using Selection in WPF, aggregating from several other answers, no other code is required (except Severity enum and GetSeverityColor function)
public void Log(string msg, Severity severity = Severity.Info)
{
string ts = "[" + DateTime.Now.ToString("HH:mm:ss") + "] ";
string msg2 = ts + msg + "\n";
richTextBox.AppendText(msg2);
if (severity > Severity.Info)
{
int nlcount = msg2.ToCharArray().Count(a => a == '\n');
int len = msg2.Length + 3 * (nlcount)+2; //newlines are longer, this formula works fine
TextPointer myTextPointer1 = richTextBox.Document.ContentEnd.GetPositionAtOffset(-len);
TextPointer myTextPointer2 = richTextBox.Document.ContentEnd.GetPositionAtOffset(-1);
richTextBox.Selection.Select(myTextPointer1,myTextPointer2);
SolidColorBrush scb = new SolidColorBrush(GetSeverityColor(severity));
richTextBox.Selection.ApplyPropertyValue(TextElement.BackgroundProperty, scb);
}
richTextBox.ScrollToEnd();
}
I prepared a little helper for the RichTextBox control which makes it very easy to generate colored text on the screen:
using System.Collections.Generic;
using System.Drawing;
using System.Windows.Forms;
namespace Common.Helpers
{
public class ColouredText
{
public string Text;
public Color Foreground;
public Color Background;
public ColouredText(string text, Color foreground, Color background)
{
Text = text;
Foreground = foreground;
Background = background;
}
public ColouredText(string text, Color foreground) : this(text, foreground, Color.Transparent) { }
public ColouredText(string text) : this(text, Color.Transparent, Color.Transparent) { }
}
public static class RichTextBoxHelper
{
private static RichTextBox _AppendText(RichTextBox box, string text, Color foreColor, Color backColor)
{
if (string.IsNullOrEmpty(text)) return box;
box.SelectionStart = box.TextLength;
box.SelectionLength = 0;
box.SelectionColor = foreColor;
box.SelectionBackColor = backColor;
box.AppendText(text);
box.SelectionColor = box.ForeColor;
return box;
}
private static void _UpdateText(RichTextBox box, IEnumerable<ColouredText> newTextWithColors)
{
box.Text = "";
foreach (var text in newTextWithColors)
{
var foreColor = text.Foreground; if (foreColor == Color.Transparent) foreColor = box.ForeColor;
var backColor = text.Background; if (backColor == Color.Transparent) backColor = box.BackColor;
_AppendText(box, text.Text, foreColor, backColor);
}
}
public static void UpdateText(this RichTextBox richTextbox, IEnumerable<ColouredText> text)
{
if (richTextbox.InvokeRequired) richTextbox.Invoke((MethodInvoker)(() => { _UpdateText(richTextbox, text); }));
else _UpdateText(richTextbox, text);
}
public static void UpdateText(this RichTextBox richTextbox, ColouredText text)
{
var list = new List<ColouredText>() { text };
if (richTextbox.InvokeRequired) richTextbox.Invoke((MethodInvoker)(() => { _UpdateText(richTextbox, list); }));
else _UpdateText(richTextbox, list);
}
}
}
and now you can use:
var text = new List<ColouredText>()
{
new ColouredText($"text#1 ", Color.Black),
new ColouredText($"text#2 ", Color.Red, Color.Yellow),
new ColouredText($" "),
new ColouredText($"text#2 ", Color.White, Color.Black)
};
richTextBox1.UpdateText(text);
or simpler usage for single-line text:
richTextBox1.UpdateText(new ColouredText($"warning message", Color.Yellow, Color.Red));
This seems like a trivial issue but I'm not sure Photoshop supports this type of functionality:
Is it possible to implement use last script functionality?
That is without having to add a function on each and every script that writes it's filename to a text file.
Well... It's a bit klunky, but I suppose you could read in the scriptlistener in reverse order and find the first mention of a script file:
// Switch off any dialog boxes
displayDialogs = DialogModes.NO; // OFF
var scripts_folder = "D:\\PS_scripts";
var js = "C:\\Users\\GhoulFool\\Desktop\\ScriptingListenerJS.log";
var jsLog = read_file(js);
var lastScript = process_file(jsLog);
// use function to call scripts
callScript(lastScript)
// Set Display Dialogs back to normal
displayDialogs = DialogModes.ALL; // NORMAL
function callScript (ascript)
{
eval('//#include "' + ascript + '";\r');
}
function process_file(afile)
{
var needle = ".jsx";
var msg = "";
// Let's do this backwards
for (var i = afile.length-1; i>=0; i--)
{
var str = afile[i];
if(str.indexOf(needle) > 0)
{
var regEx = str.replace(/(.+new\sFile\(\s")(.+\.jsx)(.+)/gim, "$2");
if (regEx != null)
{
return regEx;
}
}
}
}
function read_file(inFile)
{
var theFile = new File(inFile);
//read in file
var lines = new Array();
var l = 0;
var txtFile = new File(theFile);
txtFile.open('r');
var str = "";
while(!txtFile.eof)
{
var line = txtFile.readln();
if (line != null && line.length >0)
{
lines[l++] = line;
}
}
txtFile.close();
return lines;
}
I'm trying to loop over the Photoshop preferences. This should be as straightforwards as
for (i = 0; i < app.preferences.length; i++)
{
alert(app.preferences[i]);
}
only the object app.preferences doesn't have a length and accessing each item such as
alert(app.preferences.beepWhenDone); //bool
works, but is tedious and is also possibly version dependent. I know most of them are read-only, but I'm quite keen to list them all.
This should do what you want:
alert(app.preferences.reflect.properties.sort().join("\r"));
Or actually, to also let you inspect the actual values, you could do something like this:
var prefsObject = app.preferences;
var prefs = app.preferences.reflect.properties.sort();
var prefString = "Photoshop Preferences\r";
for(var i = 0; i < prefs.length; i++) {
try {
prefString += prefs[i] + ": " + prefsObject[prefs[i]] + "\r";
} catch (e) {
prefString += prefs[i] + ": " + e.message + "\r";
}
}
alert(prefString);
I have a logic to export avery label pdf. The logic exports the pdf with labels properly but when i print that pdf, the page size measurements (Page properties) that i pass isn't matching with the printed page.
Page Properties
Width="48.5" Height="25.4" HorizontalGapWidth="0" VerticalGapHeight="0" PageMarginTop="21" PageMarginBottom="21" PageMarginLeft="8" PageMarginRight="8" PageSize="A4" LabelsPerRow="4" LabelRowsPerPage="10"
The above property values are converted equivalent to point values first before applied.
Convert to point
private float mmToPoint(double mm)
{
return (float)((mm / 25.4) * 72);

A PDF document may have very accurate measurements, but then those measurements get screwed up because the page is scaled during the printing process. That is a common problem: different printers will use different scaling factors with different results when you print the document using different printers.
How to avoid this?
In the print dialog of Adobe Reader, you can choose how the printer should behave:
By default, the printer will try to "Fit" the content on the page, but as not every printer can physically use the full page size (due to hardware limitations), there's a high chance the printer will scale the page down if you use "Fit".
It's better to choose the option "Actual size". The downside of using this option is that some content may get lost because it's too close to the border of the page in an area that physically can't be reached by the printer, but the advantage is that the measurements will be preserved.
You can set this option programmatically in your document by telling the document it shouldn't scale:
writer.AddViewerPreference(PdfName.PRINTSCALING, PdfName.NONE);
See How to set initial view properties? for more info about viewer preferences.
I am trying to write a script that copies a layer from one document into another.
var srcDocName = 0;
var destDocName = 1;
var layerNameOriginal = "Original";
var layerNameCopyTo = "Destination";
var destDoc = app.documents.item(destDocName);
var layerSrc = app.documents.item(srcDocName).layers.item(layerNameOriginal);
try {
layerSrc.duplicate(destDoc, ElementPlacement.INSIDE);
}
catch(e) {
alert(e)

Apparently this works in Photoshop but not in InDesign. I have been trying for ages to find some decent documentation for InDesign scripting. But all I can find is the CS scripting guide, which isn't of much use.
http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/products/indesign/pdfs/InDesignCS5_ScriptingGuide_JS.pdf
If someone can point me to a good reference to the object model I would be grateful.
After some more googling I finally found the answer:
var sourceLayer = app.documents[0].layers.itemByName("Layer1");
var destLayer = app.documents[1].layers[0];
sourceLayer.pageItems.everyItem().duplicate(destLayer);
I also came across jongware which seems to be a complete Object reference extracted directly out of Adobe CS.
You can use this script: https://redokun.com/blog/indesign-copy-entire-layer-one-file-another
The underlying implementation is basically the same, but we've added a UI so it's not necessary to edit the script every time the layer name changes.
Edit: We've been told that the solution above doesn't work with threaded text frames, so I re-wrote the script. The new implementation is way more complex but it now supports threaded TFs.
To expand on the solution offered by Loopo and offer you the ability to copy all layers from 1 document to another...
