I have a C# project (Win Forms), where a form reads an external text file, and then puts the text in a textbox on the form. What I would like to do is create a hyperlink from the text that the program reads in.
For example, if the text file reads "To go to Google, click HERE [www.google.com]", then I want the program to make "HERE" clickable, and go to www.google.com if HERE is clicked on.
Right now the program can read in the text file and recognize the web address just fine. I just don't know how to make "HERE" clickable.
Note: Due to external factors, I cannot make a button, or LinkLabel, or other object for the user to click on. The word itself has to be the hyperlink (if that is at all possible). Also, I have to read the string from an external file. I can't simply put textBox1.Text = "To go to Google, click HERE [www.google.com]";
Thanks in advance!
The easiest work-around for what you are looking for would be to add a handler for DoubleClick, and then just compare the selected text.
If it must be a single click, you want to use OnClick, and then get the test up to the last space to the left and to the right, and do the same compare.
VERY HACKISH btw.
private void textBox1_DoubleClick(object sender, EventArgs e)
{
if (string.Compare(textBox1.SelectedText.Trim(), "HERE") == 0)
System.Diagnostics.Process.Start("http://www.google.com");
}
Building on the previous response, you might want to add an eventhandler to a label instead. You should be able to format the label to be blue and underlined to look like a link, also.

Is there any method to hide a button text behind button image like bring to front or send to back option?
I only need to hide or show button image only as I have a code that coverts the original text CloseButton.text = "&Close"; to CloseButton.Text = "&Cancel";
to perform another command so I can't use CloseButton.Text = "";.
Tried this link - WinForms button with image and text but my button size is too small that it would only show the text and not the image no matter how I mix and match TextAlign and ImageAlign.
Any help is much appreciated. Thanks in advance.

Place Textbox in Button and set textbox.visible=false method
Is there any method to hide a button text behind button image like

There is no such built in but you can simply clear out the text on click event of the controls. Example: if you have radio buttons for send to back then on click of that clear out the control text saying controlId.Text = string.Empty
As #Rotem posted in the comments.
Have your code behind use the Tag property rather than Text. Easiest way out is using properties for what they were made for.
Instead of using CloseButton.text = "&Close"; I changed it to CloseButton.Tag = "&Close"; and made my code worked around it to have the same function without placing an actual Text in my Buttons. Credit this asnwer to #Rotem. Thanks.
I am currently working on updating a C# project that makes use of WinForms. One of the minor changes I want to make is as follows.
The project has a Form that currently allows the user to click a Button, which then opens a Folder Browser window where they can select a folder for the project to retrieve information from. The selected directory is entered into a TextBox after being selected. However, clicking on the TextBox also opens up a Folder Browser window. You are also currently unable to manually enter text into the TextBox.
What I want to do is (hopefully) pretty simple: I want the user to be able to enter a directory manually into the TextBox and for the project to accept that text input, and for the TextBox to not open a Folder Browser form upon being clicked.
Some other things to keep in mind:
I am not familiar with all the ins and outs of WinForms, so I could very well be missing something simple that I could do.
I am also in the process of completely restructuring the project, so if this is not possible in WinForms, but is possible in, say, WPF, that would not be a major obstacle for me in this case.
Here is the code for the Button, or at least the pertinent part, as a reference. txtProjectDir is the TextBox in question. Not much else is done with the TextBox in the code except for this part.
private void btnBrowse_Click(object sender, EventArgs e)
{
if (chooseProjectFolderDialog.ShowDialog() == DialogResult.OK)
{
clbConvertProjects.Items.Clear();
clbProjects.Items.Clear();
txtProjectDir.Text = chooseProjectFolderDialog.SelectedPath;
cur_projDir = txtProjectDir.Text;
Update: I have made some changes based on the input of several users (thanks to all of you, by the way). This is what the pertinent part of the code looks like now:
private void btnBrowse_Click(object sender, EventArgs e)
{
if (chooseProjectFolderDialog.ShowDialog() == DialogResult.OK)
{
clbConvertProjects.Items.Clear();
clbProjects.Items.Clear();
cur_projDir = txtProjectDir.Text;
I also had to change the TextBox to not be read-only, as well as remove a reference to the above method from its Event properties. Now it is able to accept user input, and doesn't open a Folder Browser when clicked into.
The only problem is this: if I only enter text directly into the TextBox, instead of selecting a folder via the browser popup, the program doesn't seem to properly accept the input (i.e., no information is being collected from the directory). Obviously, I still need to make the program accept user input, as it currently doesn't.
Update 2: After more suggestions (again, thanks guys) and good old trial-and-error, I have re-inserted the line txtProjectDir.Text = chooseProjectFolderDialog.SelectedPath; as removing it from the method had undesired effects on the program's functionality. I am still having an issue with the program accepting the user's manual input into the TextBox, though.
Update 3: As per #blaze_125's recommendation, I am going to have to create a new event for the TextBox when the user Leaves it. Thank you all for the help, I appreciate it!
However, clicking on the TextBox also opens up a Folder Browser window.
The only event for the TextBox is Action -> Click, which is set to btnBrowse_Click
What I want to do is (hopefully) pretty simple: I want the user to be able to enter a directory manually into the TextBox and for the project to accept that text input, and for the TextBox to not open a Folder Browser form upon being clicked.
If you don't want that event(aka action->click) to happen, then you must remove the text btnBrowse_Click from that textbox and leave it blank. That will remove the event you currently have linked to your textbox click.
There will be an even linked to the text box txtProjectDir to check this select the text box and in the properties select the lightning bolt.
I would assume that the even is a click into the textbox however.
If this is the case you probably want to remove this.
Now in terms of how to accept what is in the text box as the value you just want to reference the text and that is in the textbox whitch would be txtProjectDir.Text
private void btnBrowse_Click(object sender, EventArgs e)
{
if (chooseProjectFolderDialog.ShowDialog() == DialogResult.OK)
{
clbConvertProjects.Items.Clear();
clbProjects.Items.Clear();
cur_projDir = txtProjectDir.Text;
I have a program that contains a list of names, and a button that displays a random name in a MessageBox. Is there any way I can add a button "Copy" next to the OK to the MessageBox, that when clicked copies the name and then closes?
If the above isn't possible, is there a way to enable copying the text in a MessageBox?
Thank you.
edit: My users won't understand Ctrl+C, Highlight and Right Click > Copy is what I'm looking for (if a Copy button isn't possible)
If a user presses Ctrl-C while the MessageBox has focus, the message, the MessageBox caption and the MessageBoxButtons labels are copied to the clipboard.
I googled your title and found this..
Or if you really need a button that says copy you can create your own MessageBox with a new windows form and then do what you want with the buttons. Open it like this to keep the MessageBox feel :
var myMessageBox = new CustomMessageBox();
myMessageBox.ShowDialog();
It sounds like maybe you are looking for the Clipboard class.
Clipboard.SetText(variableWithValue);
There is also another answer here about manipulating the contents of a Message Box.
It also might be easier to simply make a modal dialog that emulates a MessageBox without actually using the MessageBox class.
In my application, I have a textbox. I want to be able to copy text from a webpage or document open elsewhere in Windows by simply highlighting the text and pressing a global hotkey - then have that text appear in the textbox.
What I am stuck on is the selection part: I'm looking for a way to use the selected text as a variable within my WPF application, but I can't seem to get access to it in a way that makes sense.
Right now, I'm working with the clipboard and Clipboard.GetText() to get my variable :
private void OnHotKeyHandler(HotKey hotKey) {
if (Clipboard.ContainsData(DataFormats.Text))
tb_number.Text = Clipboard.GetText();
}
But i'm trying to avoid a tedious CTRL-C each time i want to get this value and work with selected text, rather than copied text. Any ideas how I can do this on-select rather than by accessing the clipboard?
I beleive the question is much clearer now. Thanks for the editing.
I dont think you can modify the clipboard functionality thru a .NET application in an easy way. But you may get what you need with a third party application for windows called autohotkey.

Just out of being bored, I decided to start building my own text editor. I have been having trouble with my coding, so my teacher had suggested building smaller programs that I wanted to write to help get me more familiar with the language, and since I couldn't think of anything, I ended up making this text editor.
I've been trying to root through the code on my own as much as possible, but I was wondering how to make the text that appears at the top of the form (beside the icon) reflect the current filename (or "new" or something if there is no file loaded) as well as having the * if the file has been edited.
I would also like to know how to code my exit button to check if the text has been edited before closing, and ask the user to save if it has, as well as having this show up if the user uses the "X" button in the corner, which currently flat out exits the program no matter what.
To change the title (text besides the icon):
Form1.Text = "This is a new title";
where Form1 is the name of you form object
To check if text is saved:
Hold a boolean variable that indicates whether the user saved the text or not.
Use the Form_Closing method to check if this variable is set to true, and do as you wish
More on Form_Closing here
Many questions :)
Let me answer a few of them:
In your own code, you should probably set a "dirty bit". In other words, declare a boolean variable that says whether or not the text changed. "Changed" is something you, the programmer, needs to define. It can mean many different things - you get to decide.
Each Winform "control" has a set of "properties", most of which you can change programmatically (on-the-fly). Your "form" has a "text" property that changes the title. Label, Button and other controls also have their own "text" property you can change at will.
Each Winform control also has a set of "events" you can override. The "Close" event is the easiest way to manage program shutdown - including if somebody pressed the "X" button. This is also a good place to check your "dirty bit", and save the file accordingly.
