So, I'm making a log in page for 'student'. I've two forms. 1) frmStudentRegister 2) frmStudentHome
in frmStudentRegister page, student will enter his first name, last name, email, major etc and will create his profile. When he clicks on 'register' button, the information he entered on the text box will transfer to the second from frmStudentHome.
I've this codes:
lblFname.Text = frmStudentRegister.txtFname.Text
lblLname.Text = frmStudentRegister.txtLname.Text
lblEmail.Text = frmStudentRegister.txtEmail.Text
lblMajor.Text = frmStudentRegister.txtMajor.Text
But when I debug it, frmStudentHome won't show those entries. It's just blank !

However how do i make sure that it takes the screen shot of the vb.net form everytime and how do i do that lol... are there any good reads on how to use an xml file as a database I work on a closed server that doesnt allow mssql or the installation of the required addon for mysql i think xml is the best and easiest way to go because I dont have access database either.

View 6 RepliesI am reading a data file and storing them in an array of string.Data is random, could be like "1","2","133,18" but sometimes there can be missing values like "?".Once I load the data in the array, I want to check if at least a majority (like 60% of them) are numeric values.If yes, then I wanna track down the higher and lowest value in the array, and output a range of 5.Loop through the array
If 60% of them are numbers (integers or decimals) then find highest value, find lowest value end if produce range
If for example lowest = 1 and highest = 100, range of 5 means 0,20,40,60,80,100 (so 5 ranges are 0-20, 20-40, 40-60, 60-80, 80-100).Also if the ranges turn to have decimals due to weird numbers, I would like to round them up.My problem is, in order to find highest and lowest when there are non numeric values in the array like "?", how should I handle those? I was thinking of something like Double.NaN but I would have to have an array of doubles.

I have the book "Visual Basic 2008 Step by Step", I am in the final chapters and have completed all of the walk through and demo programs thus far. I am a beginner but I also have a basic understanding of quite a few program statements and objects. My Goal: For the sake of simplicity I will use an example. I have a Tetris game, the player loses in the first level earns 25 points they click the save score button. , they play again tomorrow and do 1,000 levels and earn 25,000, now their score is 25,025.
Then they play my blackjack game, they gain 25,025 points when they start automatically from their Tetris game, they earn 25 points in blackjack click a save score button, now they have 25,050. [Thus far I have 2 games, and they both share a score that will need to be added to in the future]

View 4 RepliesI will use the Background Intelligent Transfer Service (BITS) to transfer files from a client (laptop) to a shared folder on a server within our local network.The problem is a very slow network bandwith, if we transfer a file, the other clients canīt work, all requests to other clients (application) or viewing internet pages needs a long time.My idea is to use BITS in my tool to copy/transfer a file from client to server, also I hope to get more performance for the internet requests.

View 1 RepliesI have a sequence that reads the selected Excel-file and displays the first row of the columns in the Excel. (The first Excel row has the column names)
Dim cmd As OleDbCommand = New OleDbCommand("select * from [" & tableName & "$]", MyConnection)
Dim dr As System.Data.IDataReader
Dim dt As New System.Data.DataTable
dr = cmd.ExecuteReader
dt.Load(dr)
With the above code I can read the the first rows of the Excel table and choose the names of the columns I like to keep. (By populating the first row to my ComboBoxes)
So, at the moment my DataTable dt has all the table header names but on the first row. And as the header names it has F1, F2, F3, ... F13.
How can I make my new DataTable dt2 take the first row of dt and make it the column names row? How can I choose which columns do I want to transfer from dt to dt2 ???
I have tried the following (Doesn't work):
Dim dt2 As System.Data.DataTable
dt2 = dt.Copy.Columns("F1", "F2", "F3", "F4")
