When reading and writing data to an XML file, in XML code, through a VB application, how does one go about commenting out a specific XML code line? From what I've gathered the original <!-- and --> tags aren't compatible. So what would be the VB alternative? Or is it just not possible to comment out a line of XML code using XML code through VB?

i have one project (let's call it project1) that is going to add properties to another project's class. The thing is I wanted to make it automatically. So in my project there are two lines of code which I want to add at the bottom of the class.vb or class.cs in a project called project2. Is it possible? If so, how?It is a data access builder software which after adding some new columns to our database we use it to generate its properties and its parameter to be added in BLL. Since we do it often (changing our database structure) I did not wanted to copy data from data access builder software and add it to project2 manually.
View 3 RepliesIf I add let's say 1 line at the beggining of a method, if I set a breakpoint through Visual Studio on the first line, will it point to the first line or the second? If it will flag the wrong line, is there anything we could do when editing .exe files to ensure a regular debugging session later?Isn't there something like setting line x to be Y? I remember seeing something like that somewhere, not sure if .NET related or not.

Basically I want to have a lines that contain certain numbers ignored. Where lines that do not contain those certain numbers show up in textbox1.text.For Instance.In the code I want it to ignore all lines that contain "1234" and "1645" when it reads Accessed.txt, and output every line that does not contain those numbers. So if a line contains "78910" it would output that line into textbox1.text.Here is what I have so far, and it works as long as I only have 1 if not contains statement. When I have more than one, it doesn't work at all and just outputs everything in the text file.

I have a piece of code that reads in lines of tabbed text. It is a game of who wants to be a millionaire. What I would like to do is get the game to incorporate random questioning.
The format of the text file is as follows:
Which record company did the Beatles create? (tab)Apple Records (tab)Sony (tab)BMG (tab)LiteFM (tab)Apple Records (tab) Which has the highest mountain? (tab)Mars (tab)Ireland (tab)Iceland (tab)America (tab)Mars(tab) With a set amount of lines. I want the program to choose each question randomly and not to repeat the question. I'm not sure how to incorporate it into the code.
