Log / Store Info And Display In Sortable Multiple Column ListBox
Mar 31, 2011
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.

I am working on a media player, and I would like to setup a local playlist feature. I am using a single ListBox and its "Display-" and "Value-Member" properties. The display is the song's Artist and Name, and the value is the song's file path (i.e 'C:UsersUSERMusicetc.').To write the file path to the .txt file, I believe I can use the following code:[code]

I'm trying to get this form to display in the listbox the address from the info from the textboxes and it works except one problem, it displays all on one line. Its seems as if it accepts the ","'s and " " for the address but ignores the vbCrLf line separator. What am I doing wrong: Here is the code for the class:

I am designing a test launch tool that I want the user to be able to select a product type from a list and then choose a station type from another list. Depending on what they choose will determine what is run (what is passed out).
The data will look like the following :
Product Station Test to load Config file to use
10-9890-1 mfgtest1 Progamming.xml config5.conf
10-9890-1 mfgtest2 Configuration.xml config92.conf

I have a listbox on my form which gets items added as the program progresses, when there are more items than the box can display, the vertical scrollbar appears, fine... so far so good.I would like the scrollbar default position to be at the bottom of it's column so that the last entered item is displayed but can't find the relevant command, I assume there is such a command.

how to correlate info from a textbox based on a listbox item selection. For example the user will select an item from the listbox, enter say the length of a song in the textbox say 2:00 for song #1, select say song #2, enter the song time for that song say 3:00, click on song #1 again and have the same textbox display the length of that song and be able to do that until there are no more songs on the list.

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 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 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

know open an xml file into a datagrid. The xml file is stored in a secured ftp with username and password. Just as an example if the site ftp.mysitesite.com, with username "xxx" and the password "XXX" has the file 123.xml, then how do I load 123 into a datagrid. Is it possible to store these info to a variable in app.Config and use that variable to access the site?

I finally got my last project done and Im updating it and making it more efficient. So instead of DGV to list users what Ive done is using a combobox to list the agents names in the database. I got that part done and I have that table as the datasource for the combox and that part works fine. However Im wanting when they select the Name from the combox it gets the values from the columns and displays them in the appropiate area. Ive tried like SELECT PhoneID FROM agents WHERE Agentname =" & comboname.text, but I cant get it to work that way.

I have a program and I get time data from a sqldb and display it in a column in a listbox. What are the proper steps for adding the time as I iterate through the data in the column? I figure I will need to do some conversions on the time to be able to add it and display it as a total.
