I wrote the code and it works great but then i thought i'd have a little challenge and go above and beyond. i decided to make a highscore leader board system. i used the following variables and sub classes to make it but im having a slight issue...
CODE:
The idea is that i wanted to make the system able to associate a name with a score, sort the score from greatest to lowest, save it to a text file, load it from the text file, repeat.
so heres a quick list of what i have working...
-Stores name and score
-Sorts by score then outputs
-occasional index of -1 issue
-saves score and name to a text file
-loads score and name when the form loads
-CANNOT add new data to the sorted list...
Thats my main issue. When i have data loaded from last time i try to add a new score to the list but then it gives me an error.
InvalidOperationException was unhandled Failed to compare two array elements
-pointing to the line...
In the details of the exception it continues to say...InnerException {"object must be of type String"}
i don't know which parameter its referring to tho, the variable name is already of type string and count is type integer.
Basically my program creates a text file based on whatever is contained in the 6 list boxes. What i need it to do is load the text it created back into the relevant list box. text file looks like...
Consignment Number-----Shippment Method------Expected Departure Date CC33-1EA------------Express Air-----------18/05/2010
I want to create a sorted list, where I enter a name in two separate text boxes(Jones, Brown) and their values in two other textboxes(200,500), then in a fifth text box I enter one of the names and it gives me a messagebox with its corresponding value. Here is my code below.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim saleslist As New SortedList(Of String, Decimal)
I have recently started using vs2008 for the linq feature but am having problems using it with a sorted list.my sorted list has a key of timestamp.I want to retrieve the first item from the sorted list having (key) timestamp <= myTimestamp.
How can I get the resulting generated list of links sorted out alphabetically according to "sTitle"? My sort function on line 272 is not giving me the results I need.
<script language="VB" runat="server"> Function sectionTitle(ByRef f As String) 'Open a file for reading 'Dim FILENAME As String = Server.MapPath("index.asp") Dim FILENAME As String = f 'Get a StreamReader class that can be used to read the file [Code] .....
I am using file.readalllines to read the file into a string, then using listbox.items.addrange and splitting by vbcrlf to insert the items. Is there a way to reduce the lag it causes for loading huge lists?
I keep track of a score system for all users in a sorted list;
dim Scores as new sortedlist(of string, integer)
I can easely increse points for a cirtain person by;
scores("peter").value += 1
Now I need to display a top x list of the users, if users have the same score, it should sort alphabetically on the name. Of course it's also possible that users have the same score.I've already tried to make a new sorted list with as key the score, and added to that score the username. Later when displaying the scores, I've replaced the username with nothing. The only problem in this solution is that the numbers are sorted on asci value which has this order:
0 1 10 2 3 4
Also, if you make a sorted list like this:
dim Scores as new sortedlist(of integer, string)
You can't have two people with the same score... So, there must be something possible with the iComparer to sort on integers right?
I can't find any way of loading all files with e.g (.txt) from a specific directory: C:UsersChristianDocumentsMy Logs I use Visual Basic 2008 .NET, this is how I try to get it:
1. When the form loads it should retrieve the full path and title of the files and then put them in the List View control.
2. When the user marks one file in the list view and then clicks a button the text content should be displayed in a multi line textbox.
I am trying to read a text file into a text box, and show the progress bar loading. Sometimes if the text file is big, i don't know when it will finish reading it. This is basically the code i use to read a text file, but i don't know how to show the progress bar.
I'm having a problem with loading two text boxes from a saved text file. I've built a log in form that saves the user-name and password on separate lines in a text file.I have a save button and a load button. My problem is that I'm new to Visual Basics and I can't figure out how to get the two lines from the file to load into their separate boxes on the form.The code that I have loads both lines from the text file into the User Name Box.Oh the username is on the first line in the text file, and the password is on the second line of the text file. Could someone please help! My Loading code is:
Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoad.Click If File.Exists("Login Config.txt") Then Dim ioFile As New StreamReader("Login Config.txt") Dim ioLine As String ' Going to hold one line at a time
I am trying to create a program which reads data from a text file and insert the data in to a SQL 2005 table, but unfortunately it only reads the first line and insert correctly but not the rest of the lines on the text file
i am using vb.net 08. I have a php file loading into a text box. and then i have an external text file. the text file looks like this:"text 1= text 2 text 3 = text 4 etc"I need the program to search for terms inside the text box that are on the right side of the equal sign and replace it with the one on the left
I picked the idea to make a little agenda for my own use and my plan was to edit a txt file using the RichTextBox. I want to use a DateTimePicker too, so that I can load a specific text file for the date chosen so that I can edit it. Does anyone have an idea how I can use the DateTimePicker to create and load certain txt files related to the same date?
I made a text file (.txt) in my project by going to Add New Item and then Text File. I want to have my text file be loaded into the rich text box i have on my form but it doesn't work. It says it can find the file. This is my code:
I am new here and just started visual basic 2008. I want to load a BIG file to edit the text. It is 24MB So whenever I load it in the richtextbox it shows : 7@ :/ Regular text files load fine. Here is the CommonDialog1Open.Filter = ("EXE [*.exe*]|*.exe|All Files [*.*]|*.*") CommonDialog1Open.ShowDialog() rt1.Text = (My.Computer.FileSystem.ReadAllText(CommonDialog1Open.FileName)) I know I am trying to load .exe! It will load if I save it through the program but will only show 7@.
So i have a text file that is created in the program which can be loaded back into the program(game save)
Whatever is in the text file "stats" should be listed in listbox1 in the same order it is in the text file. The same with "items" in listbox2. And then "quests" will be in listbox3.
The problem is when i load it instead of what is in the text file it says...
note that box3 is correct that it has nothing in it.
Getting a vibe that my VB is cursed. All I want to do is load a textfile and have the text appear in TextBox1 But no. I have looked at 3 different tutorials and I have tried copying their code word to word but still!
Public Class Form1
Private Sub ImportToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ImportToolStripMenuItem.Click
[CODE]...
And it gives me the following errors:
Error1Character is not valid.C:\Users\Saurabh Sharma\AppData\Local\Temporary Projects\WindowsApplication1\Form1.vb1067WindowsApplication1 Error2'daText' is not declared. It may be inaccessible due to its protection
i have code for loading a text file (comma separated) into my DGV:
If Not DataGridView1.LoadTextFile(TextBox1.Text, ErrorList) Then Dim sb As New System.Text.StringBuilder sb.AppendLine("Failed to load text file, see error messages below.")
[Code]....
I'm wondering...is it possible to run this code if the user was to drag and drop the text file onto the datagridview, rather than having to navigate via buttons etc...it'd make it a much nicer method!
I need to load the contents of a text file (itemInfo.txt) into a list box
Public Class MainForm Private path As String = "L:Visual BasicSequentialHW" Private Sub MainForm_Load(ByVal sender As Object, ByVal e As System.EventArgs)
I'm writing a VB.NET app where I want to load an internal text file from Resource. But the code shows Invalid URI: The Uri string is too long. The code is 'document.Load("C:UsersSouDocumentsVisual Studio 2010Projectsinfo.xml") document.Load(My.Resources.info) 'some processing job with XML node ... So, how to load the resource file ?
Trying to write an app to load a Text file and then search for substrings that contains some specific characters to compose a list. Tried first loading the text file into a StreamReader then search line by line for my substrings. Had to write a lot of code to identify my strings, but it worked ok. Then tried loading the text file into a RichTextBox then use RichTextBox.Find(......) to look for my substrings. The " .Find" property makes the code really simple, but using RichTextBox the app was really slow.
Using Stream the loop was completed in about 2 minutes and using RichTextBox in about 30 minutes! I will need to make a lot of searches and using RichTextBox is lots easier, but is too slow. Is there any way to perform search operations using Streams instead making a loop and go looking line by line??? Or what else would be a good solution to search for strings in a text file??
I'm learning to write text file from a Listbox and DataGridView, and read from it.Everything works fine until I have a small problem with reading file into DataGridView. The problem I concern is about time. For example, in my text file, I have Arrival Date & Arrival Time, but when I display it in table it is something like below:[code]
I have a few questions. Working on a program here that reads in data from a .txt file and puts it into 3 different labels during the form load procedure. I was wondering though, here's what I have so far:
Dim contents As String contents = My.Computer.FileSystem.ReadAllText("UserInfo.txt") Label1.Text = contents
1) How can I load data from Text file to DatagridView. I want it because I'm making a listener. And when I load a data from text file, i want to edit rows. And this calling the second question. 2) How can I save data, Datagrid to Text file.
I found a code Dim obj_oledb_da As System.Data.Odbc.OdbcDataAdapter Public Function ConnectCSV1(ByVal filetable As String) As DataSet Dim dataSet As New DataSet [Code] ..... I can load data with this code but I can't save.
My Text File must be like this: #IP 127.0.0.1 localhost
I want to add the contents of a comma delimited text file(PracInfo.txt) into a Dictionary on Form_Load. The contents of the file are as follows: wlvc,coadmin mrmd,thadmin ccoa,oaadmin bfhl,bfadmin trty,tradmin nppp,npadmin
For example, I want the wlvc to be the key and the coadmin to be the corresponding value. The code I have so far goes as follows: Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim sr As New StreamReader("C:Programming filesPracInfo.txt") Dim openWith As New Dictionary(Of String, String) Do While sr.Peek <> -1 strHold = sr.ReadLine() ' here I would like to use the String.Split method on strHold and then put that into the Dictionary using Dictionary.Add(Key,Value) but not sure how to do this???? Loop End Sub End Class
I know how to load a txt file into a single text box, but im having trouble loading a text file with multiple output information into multiple text boxes using commas to separate the information.
The duplicates need to stay as they are in the text file. I just want the duplicates deleted from the listbox when viewed. How would I do that? Say there are two orders made by the same user. I only want the user to show up once in the listbox...
