I have a project that is used as management for a YouthFootball Team. Part of this is adding training fees and keeping track of who has, and has not paid.This part of the project is adding the fees to the relevant textfile.Textfile - Trainingfees.txt
Each line looks like - player name|number of sessions attended|amount paid I have a form with a DataGridView. Each row is populated with: Checkbox Column, Player name in textbox column, blank textbox coloumn The user then ticks who attended the training and how much money they paid in that session.
I then have this code to loop through the DataGridview and add call a separate function that adds the relevant information to textfiles.
I am trying to add a player registration form to a textfile. And i have a few problems.One of these is that when adding to the textfile, it isnt recognising the selected value in a checkbox (checkbox is used to distinguish between a goalkeeper and an outfield player). Can you tell me what should I be writing to make this happen, - "chkGoalkeeper.??? = "" "

I can retreive all items in my notepad but when I am adding them up in my listbox, and trying to print them in the console. I can only display two strings. I don't know why. My string is a combination of a name, space & score. ex: "luke 300". That is the pattern of all strings per line in my text file. I am separating the name and the score using space as the indicator. When ever a space is found, string before and after the space is retrieved and added to the listbox
Here is my
scorelist = New ArrayList reader1 = My.Computer.FileSystem.OpenTextFileReader(My.Application.Info.DirectoryPath & "scores.txt")
create an application that calculates the registration fees for a conference. The general conference registration fee is $895 per person. The is also an optional opening night dinner with a keynote address for $30 per person. additionally, the optional preconference workshops listed in table 7-16 are available.
I was working on a project afew months ago and I came back to it and been trying to figure out how come I cant get this to work right.I cam across this site and did not know if this is how to show it but if anyone like to help me out I added a pic. [code]
So i have a program that is supposed to display charges for snowboard fees with and without boots. The charges are 20 for without and 30 with, and i have already declared them as constants. I have inputs for how many boards the user has.
My question is how do i create a summary to indicate the total number of snowboards w/ and w/o boots, total charges and average per customer.
how can i calculate the registration fees for a conference?
the general conference registration fe is $895 per person. There is also an optional open night dinner with a key note address for $30
fee introducion to E-Commerce $295 The future of the web $295 Advance Visual Basic $395 Network Security $395
the application should have to forms...which i ready made...
when the user clicks the select conferece button the form shown which i made should apper<<<i got that part done =)
. the user cannot register for the optional events, however without selectiing a conference registration of $895 ..when the close button is clicked this form should be removed from the screen and the total registration fee should apper on the main form<<<<<<< this one is the one i need to do

I am trying to create a textfile and write some lines into the textfile. However, the code that i am using can only write when the textfile is already created in the directory.
For this case, can i actually allow my script to search if a textfile is being created, if not create a textfile ???
Dim pathdir As String = "C:workingdir est.txt" If System.IO.File.Exists(pathdir) = True Then Dim objWriter As New StreamWriter(pathdir)
I have created a web application that is used within our company to track our inventory.What I would like to do is create a windows forms application that I can distribute to certain managerial staff with some additional functions.I have tried googling this, but am unable to come up with any relevant documents. What I need is some direction on how to implement login through my windows forms application that will validate login against the ASPNET_DB so that the same roles and logins can be used.
The help in visual basic express 2010 directs me to the web,My searches often pick up info on C pgms and VB 6 etc.I have been adding VB 2010 to each of my searches.e.g. Format vb 2010.How do others search for relevant info in these web searches.
I'm a relative newcomer to VB.NET so please forgive any lack of knowledge.
I'm writing a web application that lists the contents of a directory in a listbox and then (in theory) opes the file that the user clicks on.
What I'd like to do is open the listed file in it's associated application (so if it's an excel file, open excel; if it's a notepad file, open notepad).[code]...
Im trying to start a report that will generate a new word document and fill it with all the relevant bits and pieces im trying to figure out the relevant reference to add to the project but nothing springs to mind when im browsing through the references folderiv seen this and tried it and unfortunatly it doesnt work it says doesnt contain any public members or cannot be found
After I ran a disk-cleanup (in my case AVG PC-TuneUp), the loading of my VB.net project gave error on a missing file.Changing the build-configuration (DEBUG->RELEASE->DEBUG) would recreate the file and all is OK. But I have basic configuration-info for the build, maybe in more complex cases some important details could be lost when the file gets deleted.I would think an information as critical as that, would be placed in the project folder, or be part of one of the many files that make up the project, but not in the temp-folder.
I'll start off with a brief explanation of my situation. I'm doing my A-Level coursework project at the moment and am having some difficulty trying to figure something out. My project is a VB.NET Program that connects to a Database to display/add/delete/update records. At the moment I am having trouble with one particular thing which must be solved before I can move on (and the deadline is fast approaching).
I have a combo box which contains a list of different item types (Which match up to the item types used in the database, but it is not filled from the database). When the user selects one of these options, the list box below must fill with all items of that type that are in the database.
Unfortunately I'm at home so I can't get access to my coding, but I can try to explain what I've tried. I've tried so many things after trawling though what seems like endless amounts of tutorials to find an answer.
One thing that is used in pretty much all of them is the SQL string to select the needed records;
"SELECT ItemName FROM Stock WHERE ItemType = Anime"
Now, this has been used many different ways. I think the way that I'm trying at the moment is to create a new data set that contains the records that are needed for the search. There is already a data set that contains the whole table that is needed for this particular form. I think my most recent attempt was trying to copy the relevant information from the original data set to the new one, but I can't get any coding that isn't incorrect.
I have a datatable which has rows of product names. I have a table in SQL Server which has product details, with ProductID.I need to retrieve the ProductID for each product name. I can do this using a for each loop but this is way to slow. Is there a way to retrieve the relevant ProductIDs for the products with one transaction rather then using the for each loop?
I can achieve in VB what the following C# snippet does but it seems very clunky since I perform a Linq query to obtain the events for the relevant user. Is there a neat way?
ctx.FetchEventsForWhichCurrentUserIsRegistered((op) => { if (!op.HasError)[code]........
I'm really hoping I can describe this question in an understandable way. This is a puzzle that I have not been able to begin to solve even though I (mostly) understand it. I'm just not sure where to start, and I'm really hoping someone out there can get me headed in the right direction.
I have a LARGE table of data. It describes relationships between objects. Let's say the Y-axis has items numbered 1-1000, and the X-axis has items 1-1000 also. If item #234 on the Y-axis is related to item #791 on X, there will be a mark in the table where the row and column cross. In some industries this is referred to an a Truth Table. One can, at a glance, see how many items in a system relate to each other. The marks in the table can help to identify trends and patterns.Here's some other helpful stuff about the nature of the table:
The full range of the number of relationships (r) for each item on either axis can be 1 <= r <= axisTotal.The X and Y axis will share common items, but each axis will also have items that the other axis does not.Each item will only exist once per axis. It can be on X and Y, but it would only be on each one 1 time.The total number of items on each axis will most likely NOT be equal. Each axis could have from 50 to 1000's of items.
The end result is that this is going to be a report that needs to be printed. We have successfully printed a table that had about 100-150 items on each axis on an 11in X 17in piece of paper. Any more than that and it begins to be so small it's unreadable.
What I am trying to do is split the super large tables into smaller tables, but related points need to stay together. If I grab item 1-100 on X then I would need each item they relate to from Y.I've generated a number of these tables and, while the number of relationships CAN be arbitrary, I have never seen an item relate to all other items. So in real practice the range is more like 1 <= r <= (10% * axisTotal). If an item's relationships exceed this range, it can be split up into multiple tables, but that is not optimal at all.
At the end of the day I think we, and our clients, would be happy if a 1000x1000 item table was split into 8 to 10 printed pages of smaller, related tables.One other thing worth noting, there will be no empty rows or columns in the table. Every item on both the x and y axis will relate to at least 1 item on the opposite axis.
Hi, I need to program a simple Web Browser that can search for keywords and store relevant data in another file.I am facing a problem with authentication, mainly cookies and maintaining a session.So I read that Web Browser Control is based on I.E.? So may I know how are cookies and session handled?Do I have to implement them manually or are they stored and retrieved from the same folder as the one used in I.E? If so, if I delete the I.E.'s cache, am I also deleteing the cache of any Web Browser I make using Web Browser Control?
What I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.
e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.
I have a textfile which is in the following format.
[code]...
There are only 5 rows and two columns. each field is seperated by a space (" ") What I'm trying to do is display column 2 value 1 in textbox1, column 2 value 2 in textbox2, column 2 value 3 in textbox3,column 2 value 4 in textbox4 and column 2 value 5 in textbox5.
Ok so i have a text file with 20 lines (one word each line) and a for loop that runs through those 20 lineI have a string array, a random, and an integerwhat i am having problems with is having the program read from a textfile then having a random chose a random number then assigning the integer that random number then having a textbox equal that word if you get what i mean..here is my code for that
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged Dim AIWords(19) As String
I have a text file which has two columns and each column is separated by a space (), the first column is a string and the second column is a numeric field.
What Im trying is to read the numeric field in textbox1 and match it to every numeric field in column2 and if the number in textbox1 is not greater than the field then to copy that row (column1 and column 2) into another textfile.[code]...

just another little problem here! Trying to write a quiz for a college portfolio and having trouble with writing to a .txt textfile. On one form(form4.vb), I have a listbox that picks up the information held within a notepad textfile called "usernames" which contains names of quiz users. When written in manually to this textfile, my listbox picks it up fine, however, on a different form(form3.vb), I have a textbox where a user inputs their name, this is supposed to go to the "usernames.txt" textfile to be picked up by the listbox on the other form but instead, it does not write anything at all and if there is already text on this textfile, it wipes it all out.I also have to use the application.startup path instead of the usual C:my documentents etc so i would have to begin with something like this: (Note: code is a little mixed up due to messing around with different variations but this is just a example)
