I have a RichTextBox, when users type their text, quite often they enter links to some pages. What I want to do is to detect the link and make it a real hyperlink - highlight it, underline it and make it clickable. This should works for two scenarios:
when user types the link manually (so when a KeyDown event is raised)
when link is added to the RichTextBox using "paste" functionality
I found the following link: http://forum.phux.org/viewtopic.php?f=18&t=78 but it does not fulfill all the requirements (for instance, the hyperlink is not clickable and the Regex for detecting links has some lacks (e.g. it doesn't recognize https)
Can someone please help me to find out how to make the hyperlink clickable and how to extend the Regex to fulfill all the requirements?
"(http|https)://([a-zA-Z0-9\~\!\#\#\$\%\^\&\*\(\)_\-\=\+\\\/\?\.\:\;\'\,]*)?"
its for http/https. You can add ftp, files:/// etc the same way.
to make hyperlink clickable you can do somthing like that:
FlowDocument myFlowDoc = new FlowDocument();
// Add hyperlink to the FlowDocument.
myFlowDoc.Blocks.Add(new Hyperlink(new Run(MatchedText)));
where MatchedText - is the result of Regex. But not just Add(), you should to find start and end position of Matched text and perform with it action like above.

I have a textbox with a search icon next to it inside of a dockpanel that I use in every page of mine. I plan on hooking up the click of the search icon to a command and on each page it brings up the same popup with a listview, whose contents vary from page to page based on the viewmodel binding.
I would like to be able to centralize this text+search control so I can re-use the control and include it in each with a line or 2 of code - the inclusion such as and the line for binding to a different search method (if necessary).
What is the best way to do this? Create a custom or use some kind of template approach?
Please advise and if possible, describe the design and provide an example.
Thanks in advance
I am working on a WinForm Application.
The Form has many fields/components but is poorly built.
for example a field is used as user name on one case and used as folder path on the other case. Code is quite poorly maintaned.
Is is possible that when i run the application and GUI appears, i can use a tool like 'spy++' which can show me 'names' of the components (not ids). For instance the name of a button or name of a label.
Or if i can use SPY++ for 'names' please tell me?
I would solve the problem by adding a ToolTip control to your form and iterating over each control and adding a Tool Tip message to each control that is the name of the control.
First, add a ToolTip object to your form (from the Tools section of the designer.) You can rename it, but for the sake of my demo, I left it as the default name toolTip1.
Next, add a method similar to the one I'm posting below to the code page of your form. (I'm assuming this is for C# but the code is simple and can easily be modified for VB or C++).
public void AddNameToToolTip(Control c)
{
toolTip1.SetToolTip(c, c.Name);
foreach (Control child in c.Controls) AddNameToToolTip(child);
}
Finally, from within the Form constructor, add the following line of code after the call to InitializeComponent().
AddNameToToolTip(this);
This will add a ToolTip message to each control in your form. All you should have to do is hover your mouse over each control and the ToolTip will pop up a message after a second or two displaying the name of the underlying control.
Alternatively, you can recursively adding a MouseHover event to each control and when the event is fired, write the name of the control to the debugger. This would also work if you are already using a ToolTip control within your form.

The formattedtext control is a shape which helps to generate the shape of the text with proper geometry. I would like to make this control act like a text box with cursors and features like typing in from keyboard.
Right now I use an invisible text box with a formattedtext control to act like that. But the cursor position always creates a problem when the size of the text is not equal to the size of the rendered text as shape.
Can anyone please show the way to achieve this.
Well, I built a syntax highlighting textbox using the method you describes.
Actually, at first I wanted to rebuilt everything too, but I thought : I have to build the caret fonctionnalities, the selection brush, manage a lot of different events, like selection with mouse or keyboard, deletion, Copy/Cut/Paste, etc etc...
That's a LOT of work, and windows users are used to select text in textboxes for instance, so this complex implementation cannot be left unimplemented. We must follow some Microsoft guidance on how a textbox must feel.
Actually, I think that building a new textbox from scratch is not the way to go. I suggest you to continue on your current method. If you have different fonts in the same textbox, use a RichTextBox, and handle the font changes in the textbox as well as in the formatted text.
Also, a good think to implement is to only draw the visible text with the formattedtext (but only if the user can write several hundreds of text lines).
The idea is rather simple. Some datawindow (not web datawindow) varchar fields contain detailed descriptions. I was wondering if it is possible to provide the following (wikipedia-like) functionality to users: The ability to click (or dbl-click or whatever) on specific words of the text, while reading (which somehow should be indicated as clickable - it would be perfect if they could be colored blue but I don't think this is possible) and open a relevant window (or response). Do you think something like this could be implemented?
To achieve the colour, you could use a rich text edit style if you're using PB 11.5.
For the hyperlink functionality, I'd try to leverage the Clicked event, trying to identify with SelectedStart() what word has been clicked and then whether or not it is a hyperlink. The column would need to have TabOrder so that a click would place the cursor in the text.
Good luck,
Terry.
if you use a RTF datawindow you can insert hyperlinks (in whatever colour or style you wish)
I have a list that the user can filter in several ways. two of which lend themselves to combo boxes and two that need to accept user input. For example, one textbox allows the user to type in any part of a list item's description, and the dialog will only present items whose description contains the text entered.
It is a dialog 'picker' type of window, so space is at a premium. I'd like for the text boxes not to require a traditional label. Instead, when the dialog is first invoked, the label (ie, "Description") is grayed out, centered, and in italics. Maybe a tool tip to further make it obvious to the user what it's for. When the user starts to type, the faux label disappears and the entered text is normal left aligned text.
Does wpf / silverlight have any native support for doing something like this? I guess it could be a combination of styles and eventing. I'd rather not invent any wheels that might be out there (I got the idea specifically from looking at Tortoise' "Show Log" window, but I've seen it before).
Does anyone have any sample code they can share to do this? Or a an alternative idea that also saves space and simplifies the layout?
Cheers,
Berryl
Kevin Moore's InfoTextBox, which is part of his Bag-O-Tricks is the kind of thing I was looking for, almost exactly. This is also the 'watermark' (great name - I would have found this sooner if I had known that) text box from another post.
