VS 2010 Time Reading A XML File?
Jul 9, 2010
I am having such a hard time reading a XML File!!! And I believe this is quite simple.I have to read the following XML:
<?xml version="1.0"?>
<RadioAdvertisement>
<Campaign>
<OrderList>
<Order>
[Code]...
This code will create several tables in the dataset: one of them is "Adv" table, which contains ALL "adv"s from BOTH "orders". This is not what I want.I can handle this by just reading it as a text file - line by line... But I believe this is not the correct way to do this, since there are many tools in VS to do this (right?) ... and also, maybe I can learn something from this "chalange" This is when I ask for your support. How can I do this the "correct way"?

I am collecting information from a log file, one of the info that I need is the time. After collecting the time, I need to put it in an array, since there is more then on time in the log file, and for everytime there is information dependent on the time, here is what I mean:
[Code].....
And the file keeps on going. I need to be able to get the time and the info entered each. there is no specific pattern on how many time enteries per day.

im making a program to "test darwinism" in C++ and im showing the results in a VB 2010 express app, the results consist of .800x800 bmp files displaying creatures eating , reproducing and evolving. the VB app only has a picture box and it changes the .image param in a timer so that it looks like a video : for example it reads : frame0.bmp then frame1.bmp etc. I get about 30frames seconds with this method (and alot of GB of .bmp files..)the .bmp files are read slower if they never have been read.. for example I get about 5frames/sec when im using new .bmp files while I get 30fps if the files have been read once.. only opening and closing the files doesnt make them load faster, I have to load the bitmap image. I noticed that opening the directory where the .bmp files are and letting windows make preview icons make them load faster too.. that looks weird to me.. something with indexing ?also , my c++ program which creates the .bmp files goes really fast for the 500first but then it becomes slower (even if It just writes black .bmp files in a closed loop). could it be that the hard disc gets overwhelmed by all the writing ?

(First off all hi to everyone my first post!) Ok, i have two programs one program writes to a text file on a consistent basis, while the second program is opening this text file on a consistent basis for reading.. Sometimes the programs are accessing the file at the same time and the user keeps getting this error : this process cannot access the file because its already in use..
Is there any class, in system.io that i can use to modify the settings of this text file so both programs can access it at the same time?

How do you read the data from a file on the computer? I have an mp3 stored on my root folder and I want the form to read the raw data from it so I can do some encryption etc.
Dim fileOpen As New IO.StreamReader("C:file.mp3")
Dim stream As String = fileOpen.ReadToEnd
TextBox1.Text = stream

So i have one file, that has one header that tells me if the bytes are in little or big endian format.The content of the file after the file is something like this, one byte that indicates a new "section", then several bytes until the other "section". This bytes each one represent the number of the bytes that i need to read in the second section.

Here's what i've got so far, i've written all of the data that i'm going to put into my config file, however i'm having trouble reading the specific string values that I need from that ini file. The parts of the ini lines I want to get are the values in between the I've tried using streamreader a couple things but i'm having trouble figuring that out. I need to parse each line of the ini file to get that value in between the single quotations, so that I can set the value for my richtextbox background and text color as well as a few other things that i've set up in my notepad including tab spacing and so on. lots of these different values need to be converted from a string value to integers, and boolean values as well. (4 of them, the rest of them don't have to be changed because they are already string values when my application reads them to determine it's application load settings.
EDIT: I just noticed in the preview that this is from the version of the app where I had streamwriter write "______ value=" & Something to a file. lol some of the (')s are still in this version, so please excuse that little part. I had them in, but took them out so that I could trim data to get a value easier, but I want to use (')s hopefully when all is said and done.For example, just to restate what I want - in the ini file it will read [setting name] value='VALUE'I want to be able to "get" the string value of "VALUE" within the ini file between the 2 single quotations '

I have an application that gathers data from a SQL database that is used by a 3rd party helpdesk application.My application is pulling out information of the number of hours worked by each engineer for the current and previous 2 months.Also as part of this process, my application works out the target hours for each of those months.
My application has 3 groupboxes whose label is generated at runtime. My application gives the Groupbox1.text the name of the current month, Groupbox2.text the name of the previous month, and Groupbox3.text the name of the month before that (e.g. Mar, Feb, Jan).
What I am trying to do is have 2 text boxes for each month where I can enter the number of engineer holidays taken and the number of public holidays if any. I want to store these values in an XML file, and I guess they need to be stored to match the Groupbox text (i.e. Mar, Feb, Jan).
When the application starts, I need to parse that XML file and re-populate the text boxes with those number of days - BUT if the month has moved on, so that the Groupboxes are now called Apr, Mar, Feb then I want the Mar and Feb data to be loaded, and I want the XML file to be updated so that Apr is added and Jan is removed from it.I want the XML file to keep the current and previous two months figures only.

I have just recently been using VB 2010 after using VB5. I have noticed a lot of changes. The problem I have is that I wish to open and save text files to and from arrays in the background. I've attached what I would do in VB5. I have searched around, but all the examples I find use a Textbox instead of an array. Can anyone show me how I can do this with VB 2010?

I want to read a VB or C# Visual Studio project file so I can find out which files the project uses (code source files, not images or whatever).I simply opened a vbproj and csproj file in notepad and found that they are in XML format. A simple example follows. The red parts is what I need:

Does VB 2010 offer native support for reading and modifying ID3 metadata in MP3 files? A brief search through MSDN shows me nothing, and I see someone says he had to write his own library of code for it. But that was some years ago, when you had to write code to access JPEG Exif metadata, and I know that's changed with the Image class and the GetPropertyItem method; so I'm hoping MP3 files have their own methods and properties now for this.

I am trying to create a console application that allows me to read the contents of a text file and saving the data by specific name in a set of files. For example, the text file I am going to read is a tab delimited file. Some content of the file includes full name, school, location, and whatnot. I want to save the content by school name in a set of files that have the school names. In this case, everyone that attends "Central" will be saved in a file named Central.txt.Everyone that attends "Central Park" will be saved in a file named Central Park.txt.These are the sub procedures I came up with so far:
Readfile()
'Use StreamReader
WriteFile()
And I think I am on the right track of reading the text file:
Dim objStreamReader As StreamReader
Dim strLine As String
'Pass the file path and the file name to the StreamReader constructor.

I can write a 1-d string array to file with:
Dim test() As String = {1, 2, 3, 4, 5}
File.WriteAllLines("C:MyFile.txt", test)
but can't see how to write a 2-d array to file.
I've tried this:
Dim test(,) As String = {{1, 2, 3, 4, 5}, {34, 22, 12, 33, 55}}
Dim myfile = File.CreateText("C:MyFile.txt")
Dim row, col As Integer

I need to read a Visual Studio Solution file (.SLN files) to figure out which projects belong to this solution.By opening a SLN file in notepad, one can see that the projects are stored like this:
Microsoft Visual Studio Solution File, Format Version 11.00
# Visual Studio 2010
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "RadioGadget", "RadioGadgetRadioGadget.csproj", "{AE664C6C-000B-44D9-BAD8-0200D6ABE90D}"
[code].....
excluding the ... part obviously (which is just some guid I don't care about). Then I need it to match the rest too, and more importantly, I only need it to return the filename that I've underlined in the example. When I simply use 'm.Value' as I am now I think I will get the entire matched string back, right? That gets me nowhere as I'd still need to parse the filename out of that manually... Bit pointless to use regex then...

I've a got a homework assignment that chooses one of four values in a list box, stores it in a text file. Secondly, on the display click event it should access the text file, read the line, store it in a variable and then display the totals in a text box. Works sort of fine except that it doesn't display the totals correctly. Code for both buttons is below. The variable are assigned in the mainform (Tried also in the display button and didn't change anything). The save button works fine and stores fine in the text file, it's just the reading that's the problem.
Private Sub saveButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles saveButton.Click
