I'm searching files and returning lines that include the search text, and I'm not really sure the best way to display the information I get. Every time I get a match, I want to show, in some sort of control, the File it came from, and the whole text line. (aka streamreader.ReadLine() result). First I tried just putting it all in a read-only text box, but it doesn't have a scroll bar.
What is the best form control to help me display this data neatly?
The text box should do just fine. Just set MultiLine to true and ScrollBars to Auto (or Vertical, whichever suits you best).
Your best bet would probably be either a Listbox, or a DataGridView.
Also maybe have a look at Environment.NewLine Property
A ListView will work for this. Set its View property to Details, and add two columns in the designer (call them FileName and FirstLine or something, and play around with the widths as you like).
You add a new line like this:
string FileName = #"c:\file1.txt";
string FirstLine = "This is the first line of text from the file";
ListViewItem item = new ListViewItem(FileName);
item.SubItems.Add(FirstLine);
listView1.Items.Add(item);
You could use a list box to list the files in which the text was found, and then, a text box containing the text you want to show. You should be able to work if you do like Fredrik Mörk said.

I'm attempting to make a command prompt clone in C# so I can get familiar with using IO. However, instead of just one text body, I created two text boxes (one for the command and another for the "parameters") and a rich text box to view the result of the commands. It may sound confusing and the title may be misleading, but I didn't know how else to word it. Anyway, my question is- how do you make only the current line editable and the rest read-only? And how would I be able to combine the commands and parameters in the two text boxes so I wouldn't need two separate text boxes? I have spent 6 days trying to figure out the logic to implement this but I got nothing.
Here's a picture of the form:
And here's what I want to make it similar to:
I'm not sure if you can do that, but if it was me, and this was a "get it done now" situation (and this is just off the top of my head), I would create a user control to contain the "screen". This user control would have the RTF or list box as the top, and a textbox flush under it.
I would remove the borders and wrap both these controls in a panel that has borders. This would simulate a single control.
The textbox would check for the enter key in one of the key-press events, and the control itself would have events that could be handled by the parent control.
This may be hacky, but it would probably be what I'd do in a last minute situation.
Oh as far as the command and parameter stuff, if you read the textbox as a single value, then split the string into an List or array, you could then define a switch or some other conditional code that would know what to do with parameters (index 1+), based on the value of the first item/index.
I've got a dialog box that pops up with a dynamic list of numbers, and I'd like to get the box to wrap the text because at the moment it displayed up to screen width and then cuts the rest off.
I know I can use \n to declare a new line, but the list is dynamic - it could be one item, it could be 20.
Is there any way to tell the dialog box to wrap text?
Edit: clarification + example code
I'm not using MessageBox.Show() - our code uses its own defined message box class, but the guts of it calls System.Windows.Forms.Form.ShowDialog(parent). Maybe this isn't as well-behaved (i.e., doesn't wrap) as MessageBox.Show()?
Create your own simple form and add a label. Do the wrapping there... You cannot do that much things with Dialog boxes.
In this way you have much more flexibility to show your information to the user.
Are you using the System.Windows.Forms.TextBox? It has a property WordWrap that you can set to true
No other way for a standart MessageBox. Only creating your own form.
You could programmatically format the text by restricting each line to a specific number of words then inserting a \n or Envoronment.NewLine
i was wondering if it is possible in c# to set to a text box a list of strings that are clickable links? at the moment i can set the text box like this
txtBox.Lines = values.ToArray();
ideally though i would like them as links if possible? maybe link labels or something?
(I'm assuming you're using Windows Forms; the answer for WPF/Silverlight may be slightly different.)
A textbox just contains text - it's not "rich" enough to have links.
If you want a list you might want to consider using a ListBox of some description - or possibly a RichTextBox; I haven't tried creating links in a RichTextBox, so I don't know whether it's possible.
Of course, you haven't specified what you want to happen when the user clicks on the links, either...
Use RichTextBox and check this - http://www.codeproject.com/KB/edit/RichTextBoxLinks.aspx
You can try using Windows.Forms.Controls.LinkLabel. It allows storing multiple links along with the text in it.
I have a label on my form which is used to display a path. Occasionally the path is too long to display, so I turned on AutoEllipsis, but it always seems to truncate the end of the string (which is the more relevant part in my particular case). Is there any way to get it to automatically truncate the beginning?
Is there another control that I can use to display the path?
There is a project on The Code Project that looks like it does exactly what you want: Auto Ellipsis. There is a demo that you can download along with the source.
The easy way is do a trick by using textbox instead of label, just design it like a label then do this
textBox1.Enabled = false; //so it will not be selectable like label
textBox1.SelectionStart = textBox1.Text.Length; //so it will focus on the last character on the textbox
This is my first tryst with C#. The form that i have in mind consists
A textfield which will be supplied with the path of an executable.
A "Run" button which will call the executable(cosole app)
The executable console output should be displayed in the rich textbox.
Now when i click on a line in richtext box, i select and get the text in the line. This text maps to some other text info. I need to display this text info as a tooltip over the line.
More explanation:
The output of the exe is displayed in the text box as
Address1=Value
Address2=Value
Now when i click the line "Address1=Value", i map this text to find some info regarding what bits are set like
enable : 1
select : 0 ..etc
this info i need to display as tooltip over the line. Is such a thing possible? Is there better alternative to RTB/tooltip for this problem?
Thanks

I would recommend using a ListBox for each string of data returned and then if you use a tooltip it makes alot more sense because you are hovering over a list item specifically not the whole text field.
Using the ListBox and items should make it alot easier to work with overall since it will be separating them into defined items instead of just appending lines to a text box.
Also I think you might have alot of work in store for you for trying to make the text box behave the way you want it to for it to treat each line differently dependent on the text of the line.
If you're using the textbox because later you want to be able to select all the output to copy and paste it I would have the textbox hidden by default and have a button that says like "Toggle Raw Output" that will show/hide the text field so users can get the text easily. While using the ListBox as the primary display for information.
What I understand from your question is that when you click on the line in the RTB, your code scans the text on that line, identifies the extra data associated with that line and then inserts it into the tooltip for the RTB.
Technically I believe that this is possible to do - although I am not 100% sure of the mechanics of inserting tooltip text. However as a user interface feature I would personally not do that as the tooltip text is displayed whenever the mouse pointer is anywhere over the RTB. Thus if a user clicks on line #1, (and sees the data associated from line #1) but hovers the mouse of line #3, they might think that the tooltip is associated with line #3.
You could alleviate my concerns with a strongly worded tooltip, but I feel that what you are doing is misusing the tooltip for something other than what it was intended to be used for. IMHO it may be that you are better off displaying your data with a tree control rather than with a RTB, as the tree control more naturally expresses the functionality that you desire (click on a node, expand it to see details etc).
