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.

I have made a custom MessageBox for my application and it launches as a UserControl. I have two buttons inside it and I would like to allow users to press Tab to switch between Buttons. However, since it's a UserControl overlaying the content, Pressing tab more than twice makes the focus go in the background on elements that aren't supposed to be tabbed at.
I can't figure out a good idea how to prevent this, I've thought of making a method that will select all elements and make their IsTabStop values to false and then restore them later, but I think that would be more of a problem then a solution.
Is there a way around this to limit tabbing only to the UserControl?
I would also appreciate advice on working with the message box.. the whole messagebox is an async function that has an infinitive loop until the answer is given. Is there another way to stop the application until one of the message box options was selected?
Crowcoder's reference has lead to correct MSDN page where I found my solution:
dialog = new UCMessageBox("Are you sure you want to exit the application?", MBType.YesNo);
AppMessageBox.Children.Add(dialog);
KeyboardNavigation.SetTabNavigation(dialog, KeyboardNavigationMode.Cycle);
The key was to call .SetTabNavigation function and direct it to my dialog (custom UserControl for the message box) and setting the KeyboardNavigationMode to Cycle.
After closing the UC rest of the application continued normally regarding navigation.
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.
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.
I have a WinForms application, and when it is finished running, displays a message box with just an OK button.
Is it possible to have an OPEN button on the message box too?
I found this code online:
public static DialogResult Show(string text, string caption, MessageBoxButtons buttons);
But it only gives basic commands, like Yes / No, OK / Cancel, etc. It doesn't show any open button.
I want to OPEN a text file after my program has finished running.
Any help would be greatly appreciated.
No, you can't have any other values in a message box rather than the default, the MessageBoxButtons is predefined enum and you can't add to it. The solution is either use some custom message box, check this, or implement your own MessageBoxForm and add your custom settings to it, check this.
The MessageBox.Show methods exposes serval overloads. You can use one of them as you like. To invoke a MessageBox, simply execute following line:
MessageBox.Show("Hi");
For information you can find on MSDN.
I have a created a custom keyboard shortcut for my application,
when the user press combination keys of CTRL + ALT + Q, i show
a messagebox "Are you sure you want to log out ?" Then if clicked
YES, i log out of the application.
Problem :
I want to make sure that, only once instance of message box shows.
No matter how many times the user presses the shortcut.
currently it shows multiple message box, on pressing multiple
shortcuts.
How to overcome this ?
From MSDN
A message box is a modal dialog box,
which means no input (keyboard or
mouse click) can occur except to
objects on the modal form. The program
must hide or close a modal form
(typically in response to some user
action) before input to another form
can occur.

Taking ck's comment into consideration...If you are showing a custom dialog (form) then you need to invoke the form using Form.ShowDialog() and not Show().
A quick and dirty way would be to have a class level boolean variable that tracks when the user is trying to exit. If they are, it's set to true, and your routine to display the dialog box can check this flag, then return without doing anything.
Seems like Singleton Pattern is your option.
I think you can create your own form and use the mymessageboxform.show() method, and check its dialogue result.
You'll want to make your application single instance so it can only be started once.
