User Entry Screen To Store And Retrieve Info
Apr 10, 2011
I am trying to learn VB.NET and I've written a user entry screen to store and retrieve information. I keep getting this error. I understand that I have to either change the ref value from the calling code, but my problem is where is the calling code? Here is the error I'm getting (the program is underscoring udtTrans in the FileGet line in this segment).
Private Sub viewRecords()
'open the file and read fields of the first record into the textboxes
Try
FileOpen(1, strFilename, OpenMode.Random, OpenAccess.ReadWrite, OpenShare.Shared, Len(udtTrans))
FileGet(1, udtTrans, intCurrentRecord) 'gets first record

I need to convert a large VB6 app to vb.net which does a lot of database work and produces a Crystal Report. The initial form is simple a login form which validates the user. I am trying to use a datareader to retrieve the user's login info but it won't compile on the statement where I'm trying to get the Connection String from the app.config file. It complains that the ConfigurationManager is not declared on the dim statement. Where and how do I declare the ConfigurationManager? I thought it was just pointing to the app.config file but apparently that is not correct. [Code]

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()
End Sub

I'm new to developing and I work for a small company. I do have previous Microsoft Access experience and have used VBA code to enhance Access applications. But now I have been asked to develop a form for data entry using VB.NET. Is it possible to create a data entry screen from VB.NET that adds, saves, retrieves and manipulates data without using a database for storing the data. Users will not have Microsoft Access (or any other database) installed on their machines. They will only have the .exe file that I create after compiling the VB.NET application.

I have a oracle database. I use the OracleDataAdapter(Oracle.DataAccess.dll) for select, update, insert, delete operations. I don't set any (table) locks on my own(I only start a transaction). I have a oracle table named "test" with the entry "test1".
Now my question: Can Person A read the entry "test1" while Person B is updating/deleting the entry at the exact same time? What happens in the worst case? An old match/empty match or can it cause any kind of exception/error(e.g. "TableLocked-Exception")?

I have just added a login form to my main form which just has a username textbox and a password textbox. What i basically want a user to be able to do is enter their username and password into these fields and then for the form to store the values there.
So if they enter their username and password, and then click OK on the login form, if they were to open up the login form their details would still be there?I want to be able to call on these values else where? How do i store the info in the username and password fields? And if they then closed the form and opened it up again would it still remember what username and password had been entered?

I am making a video conversion tool. I have a listview with one item per file.And i also have options to add subtitles to movies. I want it to be like this:Say the user add 2 movies. He select the first movie in the listview and then go to the subtitle tab beside. There he checks a checkbox so he can add subtitles. Some controls comes up that allows he to browse for subtitle and select which language the subtitle is. Then when he has selected these options, he select the other movie, the program saves the subtitle data somewhere and then erases all fields so he can fill them with a subtitle for the other movie.
My.Settings is way to simple for this. But i don't want SQL or db related stuff.Is there a good storing way i have missed?

I am very new to collections and most of the applications that I build are Create, Read, Update and Delete type applications that don't really need arrays so I have almost no experience with either.
This is what I have so far.
VB

Dim iDays As Integer = NumberDaysPerMonth(Date.Now)
Dim DayNumber(iDays) As Integer
Dim EmployeeRecords As List(Of String) = New List(Of String)
For i = 1 To DayNumber.Count - 1

I am writing a program that lets someone click on a picture to vote for their favorite pet. The part I am stuck at is: when the application is opened and closed it needs to remember how many votes there were. To do so, when the program is closed I have the information stored in a .txt file. it looks something to the effect of:
name, type, votes
andy, bear, 0
bart, dog, 0
candy, cat, 0
hopsie, bunny, 0

I am using the following SQL statement to retrieve information from an access 2003 database but this command keeps stripping out the proceeding 0 from the number of the month. The variable is called TBookingsDateFulldate

Basically I'm adding a registration feature into my program, or a similar thing to that. So, when you purchase you can install up to 3 copies (for example), but not more.To do this, I need to know some kind of information that is unique to each computer (to store in my database online), I thought of the name of the computer, but that isn't unique, obviously.

I am wriing a vb.net windows application to log and store information. then display it in a sortable multiple column listbox (I personally like FlexGrid by Component One). However... I am not sure how to go about storing the information. Should I go with a .sdf file database, registry, simply storing them in a file, or some other method?
What I need is to be able to:
read/write/delete from it
read possibly up to a 20mb file and sorting it without a lot of lag
be transported to multiple systems and maintain these writes (installed on many systems)
I know I could split up the reading/writing to anther thread. Even to other .DLL's and whatnot. But as for storing. Not sure what the best option is.

writing user info such as user, computer name, date, and time to an acces database using a button click event. Then use a query to check if the user has accepted the aggreement. If the user has accepted the aggreement then call a vb.exe that display the aggrement. I have a login script that runs the vb.exe and uses a button click that records the user info to a csv file, but if the user has already agreed to the policies I do not want it run again.

I can't seem to find any answers that work. Here's the setup:
Info class: Public Class ProductStageInfo
[Code]...
maybe I just don't understand the whole collection/index/thing. All the examples I've found are regarding single dimension collections - 'how to find name within this collection', and the responses use strings to search through them, but somehow the Info class is being treated differently, and I'm not sure how to translate this..

I am trying to read the pc system information so that I can retrieve the time and date format.
My code below:
Dim Info As System.Globalization.DateTimeFormatInfo
Info = System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat
Debug.WriteLine(Info.LongDatePattern)
Retruns in debug: "dddd, MMMM dd, yyyy"
So I have 2 questions;
1) Why is there, a dd after the MMMM.
2) My company has small franchise branch offices round the world - France, USA, etc. What I am trying to do is get the date format so I can decide what country I am in - then when I print out the date on my order labels I can change the date format to suit Americans or Europeans etc.

I have been trying to solve this for 2 days now, every text book I own and google have been well and truely exhausted and I am still no closer to solving my problems.I have a login facility reading in user info from a main user file. This takes all info into a temp array and then splits usernames into a username file, passwords into a password file and a current score in a score file.
I have the login working fine and everything else in my program works as intended but touching up cosmetic aspects I want to add a Message box after login to say hello and display current score. This works great for the first name in the user file i.e - after login User1 welcome to the game. Your current score is 45 As intended.But the problem arises with any other users, my message comes out as
User2 welcome to the game. Your current score is 55 I do not understand where the random new lines are coming from. I have tried assigning the message as a variable and removing new line using

We are trying to store and retrieve datatable as blob (varbinary(max)). We convert the existing datatable into an xml file and store that xml file as a blob and while retrieving we get the blob as xml file and convert it back to datatble. It seems to be storing and retrieving the xml object but having issues while converting it back to the datatable ("End of stream - error").
