I am working with VB 05 Express, and I know C has this, but I want to comment multiple lines of code, without always having to put the little ' symbol on ea. line. Like, I think C has something like this-
I used to be a C# developer so this commenting style was very easy in C#. This is driving me crazy but how do you do this in VB.NET without getting a syntax error?: Private ReadOnly Property AcceptableDataFormat(ByVal e As System.Windows.Forms.DragEventArgs) As Boolean
give me a working regex expression (C#/VB.NET) that can remove single line comments from a SQL statement ?I mean these comments:
-- This is a comment
not those
/* this is a comment */
because I already can handle the star comments.I have a made a little parser that removes those comments when they are at the start of the line, but they can also be somewhere after code or worse, in a SQL-string 'hello --Test -- World' Those comments should also be removed (except those in a SQL string of course - if possible).Surprisingly I didn't got the regex working. I would have assumed the star comments to be more difficult, but actually, they aren't.
As per request, here my code to remove /**/-style comments (In order to have it ignore SQL-Style strings, you have to subsitute strings with a uniqueidentifier (i used 4 concated), then apply the comment-removal, then apply string-backsubstitution.
I am trying to use the xml comments suggested (with VB in a ASP.net project in Visual Studio 2008).I want to give examples of how to use a class, for example, so I write [code]This is readable in the code itself, but the resulting help information in the Object Browser is unusable.The summary, parameters and returns stuff is OK,but the example code is all as one block, with a single space instead of the line endings.I know that most XML treats all whitespaces the same (space, line ending, etc.) but since <code> is described as being for multi-line code blocks, I expected it to respect line endings and indentation.Ideally it would colour-code the code as visual studio does, but the least it should do is respect space (similar to the HTML <pre> tag).Otherwise how is it useful for multi-line code blocks?
I've noticed that in C# XML comments and code comments can have different colors by changing the settings in Tools > Options > Environment > Fonts and Colors > Display Items:
- Comment: controls code comments XML comment: controls XML comments
This works well in C# <summary>This XML comment is green</summary>
.Basically I'm trying to code a program to output class names for a game which then allows the user to copy and paste the string of class names into the game itself.The template for class names in the game look like this ["name",quantity];So in the code for btn_add I have (which outputs to a text box):[code]How can I change the ' into "s without VB.net throwing up errors?

I'm having a little trouble deleting multiple lines for a listbox. I know how to remove a single line, which is this: [code]If I change the value for IndexOf to SelectedItems, I get an error stating that -1 is not valid for index.I am guessing this needs to be done using an integer array and a for each but I don't know how to do that. I really never bothered to look much into arrays.
I'm dealing with the dreaded <Run/> in Silverlight 3 and having to programmatically create a <TextBlock> and its inlines:
Why dreaded? Because it doesn't work, I guess, the way you'd expect. Exhibit A, below, should produce BARN (with fancy colors for each character), but instead it produces: B A R N
EXHIBIT A
<TextBlock FontFamily="Comic Sans MS" FontSize="88"> <Run Foreground="#A200FF">B</Run> <Run Foreground="#FF0000">A</Run>
I am attempting to remove information from an html file, using known 'tags' (not html tags, just short sequences that only occur where my information is). My code worked fine until part of one tag was on a seperate line. Here's the function I have been using: (OriginalString conatins the HTML file)
This is one of my first steps into the magnificient world of visual basic. I looked on many forums, but most of the time the questions asked are much more complex than mine. I am looking for a piece of code for the preparation of multiple graphs in excel 2003.
I need to add this line to a text file that is going to have other information added to it several times. I also need to add this line and have the number change every time the additional data is added.
i notice that when i start next line of code and i press enter, it recompacts itself and the continued line moves left a bit... then if i place focus on the second line and press enter again, it (the second line) moves to the left some more, and it keeps doing this every time i focus on second line and press enter. how can i make it so that my second (and third etc) lines are formatted in a pre-determined way so they are always a certain amount of tabs indented to the right from where my line 1 starts?
I am making a basic form that has 1 button and a rich text box.I need to click on the button and have it call a random line from 3 text documents (so 3 lines total) and place them in the rich text box, each on a different line.

i need to code a program to help me in my everyday job, i own my own business and this will help me with my sales. its a very simple program, and i cant figure out how to get my multiple textboxes to write to a new .txt file. i can only get it to do 1 line at a time. I have textboxes. named txtDate, txtCarrier, txtLocation, txtDateEmpty, txtDestination, txtQuote, txtPhone, txtFax, txtEmail.I want the "txtDate" textbox to be autofilled with the current date and time of the user input, which is started on the next textbox.the rest of the textboxes are going to be user input. then when the user is done entering data into the multiple textbox's they would click a button "add" or something to that sort.then those text box entries including the "txtDate" would be written to a new .txt file.in this format, Quote"Date - Carrier - Location - DateEmpty - Destination - Quote - Phone - Fax - Email "all on the same line.and when the "add" button is clicked, the multiple textbox fields clear all the data previously entered.and is ready for another user input.
after the 2nd set of user input is entered, and "add" button is pressed,it would add(append) another line to same txt file previously written. example: Quote"Date - Carrier - Location - DateEmpty - Destination - Quote - Phone - Fax - Email " "Date2 - Carrier2 - Location2 - DateEmpty2 - Destination2 - Quote2 - Phone2 - Fax2 - Email2 "
then the previously filled text boxes would be empty again, and ready for input 3. and with this you would be able to add countless lines over and over of user input.ok, also when the program launchesI want a msg txt box to pop up and ask. "Where is the Load Origin?" then the user would input data and click enterAnother Msg box would pop up and ask "Where is the Destination?"Next "Pick Up Date" then "Deliver Date" and last would be "Notes" and all that data that was entered into the msg box's will Be at the top of the txt file like a header .

I am developing an application with multiple picture boxes, each displaying a line graph. I want to be able to have a label following the mousepointer showing xy coordinates of the point. I also want to allow a user to zoom in on a specific picture box by double clicking on it. The code does what I want as written (changes backcolor so I know double click event fires) except moving the position of the label to follow the mouse pointer.
However if if uncomment the line in the MouseMoved sub: LB.Location = New Point(e.X, e.Y) Then the label moves as desired however the double click event no longer fires.
