VS 2005 Reading Files And Placing Them In A Collection?
Jul 23, 2009
I have created football (American) play creator. When the user is satisfied with a play he has created it is saved it as a file with a .play extension. What I want to do is to cycle through all the files in a folder (probably named after the team), and place each one that has the .play extension into a CList (of ClPlay) collection.I have been able to successfully load one play at a time by using this code...
Dim fs As Stream = New FileStream(diaOpenPlay.FileName, FileMode.Open)
Dim bf As Runtime.Serialization.Formatters.Binary.BinaryFormatter = New Runtime.Serialization.Formatters.Binary.BinaryFormatter()
Dim Play As CLPlay
Play = CType(bf.Deserialize(fs), CLPlay)
...but that was when a specific play was selected from a load dialog box. This time I want to load all the plays in a folder and store it in a collection, and I'm not sure how to modify the above code to do that.

I want to read a text file with unlike delimters into a collection.This is what the file looks like:
_Item 4916 0.00 781.21
_Item 2831 0.02 842.25
there are 10029 items and i am trying to get each items description into 3 different collections: Item "names" (first column), Item "weights"(second column), and Item "values"(third column).the delimiters are as follows:
______(3 spaces)____(1 space)____
considering the amount of items in the file, it would be a complete waste of time to edit it.

Im currently working on a program that will download some files and place them inside a folder. The tricky part is that the folder they have to be puttet into is a .jar file. The jar file is always the same place, and that is in %appdata% the full location would be "C:UsersBrugerAppDataRoaming.minecraftinminecraft.jar". With "minecraft.jar" beeing the destination for the files
Ps. Im trying to create a mod installer, since some people are having a little trouble installing mods for minecraft. Minecraft can be found at [URL]

I have second column as datagridviewTextBoxColumn column in the datagridview, after opening dot net form runtime, in first cell of this column , I am populating �-� character at third position with remaining everything blank. Requirement is cursor should be at first position in this cell.
But now what is happening is, as my second column�s first cell should have cursor after opening form, we are sending tab key from first column to second column runtime with SendKeys.Send("{TAB}") as result cursor is located after �-� which is not requirement , cursor should be at first position in cell.

I am working on a small program that reads items from a text file. The items are the split up into data and used to fill the menuItem() as menuItems. Each instance of menuItem has 3 properties (name(string), price(double), and menuType(string)). As an item is selected, it's price is added to the Order collection with :
Order.Add(menuItem(index).price)
The running total of the sum of the selected items is to be displayed in text box. I have,
txtTotal.Text = FormatCurrency(runningTotal()) ' with runningTotal as a function
Function runningTotal()
For Each menuItem As MenuItems In Order
[code]....
However, when run, this error appears. This is new coding to me, so if I'm just way off, let me know. Anywho, I tried with & without the CDbl. It doesn't seem to have any effect.

I need to pass a file's name as an argument and a switch to the executable I'm using.I'm doing it like this:
vb.net
proc.StartInfo.Arguments = "-z ""C: est.txt"""
I'll know where the files are that I need to grab, but I won't always know the exact names. So, I thought I could grab a collection of the files, store them in a variable, and then pass them as an argument.I tested it with one file like this:
vb.net
Dim File As New System.IO.FileInfo("C:...Desktop est.txt") Dim proc As New Process proc.StartInfo.WorkingDirectory = "..." proc.StartInfo.FileName = "....exe" proc.StartInfo.Arguments = "-z" & File & "additional arugments" proc.Start() proc.WaitForExit()
But, as you all may already know, I can't use the & operator with a string and FileInfo.Would I have to then convert the FileInfo to a string first and then pass it through?

'shows text property of the clicked button
MessageBox.Show(sender.ToString)
End Sub
is there any efficient way to do this?

Is the memory from primitive data types (int, char,etc) immediately released once they leave scope, or added to garbage collection for later release?
consider:
For x as integer=0 to 1000
dim y as integer
Next
If this doesn't add 1000 integers to the garbage collector for clean up later,how does it treat string objects? would this create 1000 strings to clean up later?
For x as integer=0 to 1000
dim y as string=""
Next
How about structures that contain only int,string,etc... data types?

I tried this
vb
Dim matches As String() = Regex.Matches(tmpFieldContent, strEmail).Cast(Of Match)().ToArray()
But it didn't work, as vb says
'Cast' is not a member of System.Text.RegularExpressions.MatchCollection'.

I often use a for/next loop to cycle through a collection to find a particular member of that collection based on some criteria. This works fine in every case except one: when I want to then erase the very member of the collection I just found. For example, if I wanted to give the heave-ho to every obect in a collection class that has a member veriable Color equal to Red:
[Code]...
The problem is once the collection class member is erased it makes to loop invalid because taking out the member reduces the total count of the collection in the middle of the loop. Eventually I get a "Index is out of range" error.This circumstance has bothered me every so often; I bet more experienced programmers have a different type of loop system that works better than this when you want to erase a collection member.

I am populating a collection from some tables in the database which serves as a look-up from controls (combobox) I am using but what I want is rather than hitting the database each time can I just cache the collection and get the collection from the cache? The look-up table may or may not change all the time so I would want to have a way to validate if the cached collection is still valid or not.

This I'm almost certain is an easy problem for those with more experience than me. I just need a routine that trades the places of 2 members of a collection class.
For example: If there are 5 objects stored in a CList of() collection class, I want to swap item # 3 and #5 (or any pair of indexes), what would be the code?
This simple problem has my head spinning because once you remove a member all the indexes change.

I am trying to make a collection of controls that I can loop through. So I have this code in my form... Dim WizardFrameCollection As New Control.ControlCollection(Nothing)
I then try to add controls to the collection by I get a error "Object reference not set to an instance of an object." WizardFrameCollection.Add(Me.GroupBox1) I am not sure why I am getting this error. Groupbox1 is a groupbox that is on the form.

I was wondering if anybody had heard of a library, preferably a .NET assembly, but Java will do as wel, that allows you to read the data in a Guitar Pro file (.gp3-gp4-gp5)I have this gigantor of a folder with about 50.000 song files, and would really love to write something that can actually archive all these files, for easier searching. And basic information like the tuning of the instruments in the song would be very useful parameters to retrieve from the file and add to the database.
I have searched the web but have yet to find anything like this, or a file definition for writing my own parser.

I'm creating a simple forms application where users can enter their details and save the information to a .ini file because I needed this for a simple game profile. I've tried to make it write "Name =" + txtname.Text but it won't work anymore. And as well as that, I don't think It will load the text back from the ini file.
Here's the code I used;
Public Class Form1
Dim hFile As Long
Dim sFilename As String
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
