Storing Information To A Listbox Selection?
Dec 21, 2011
I am creating a program with multiple Forms designed to track multiple projects.The first form is designed to setup new projects and obtain previous projects, from there the other forms open to be filled in with information.For new projects the next forms open blank but I then need these later forms to be tied to this project name so that it can be selected from a combobox and the information will be already populated.tieing the information on the later forms to the projects populated in the combobox so that it appears when a specific project is selected.Is this able to be done without creating databases?
As an example, say I create a new project then a new form opens and I add some information to a textbox.I would then like to be able to save the information so that the project name moves to the combobox on the first form (I can handle this) and the information input in to the textbox is tied to the project name so that when the program is reopened and the project name is selected the second form opens with the textbox populated.

I'm curently trying to get information displayed in a listbox from a selection made in a datagridview. For example a user selects an artist from the treeview control and it displays all the albums by that artist in the datagridview. Once a user selects an album all information for that album is displayed below the datagridview in either a listbox or listview control. I've tried dragging the conrols from the datasource and it' won't drag onto the listbox. What do I need to do to get it so that it will display album, artist and track information?

im writing a program for my vegetarian girlfriend that does two things from the main menu. 1: add foods with attributes like name, iron content, protein, sodium etc. 2: use the foods that have already been stored and use them to make a balanced meal. What im having trouble with is, how do i save the attributes when storing the foods ? i have knowledge with c++ so i understand how classes work and was wondering if there is something similar in Visual Basic.

I am making a program that stores information for my applications. There are 4 main things I need in the XML file, the login information (User name and password), Application names and keys, and the owner of the application (who bought it). The program allows the user to enter as many applications and owners as they want and once login information is correct it loads the data. Then on exit all the data saves to a XML file.
My XML file looks like this
<Data>
<Login>
<UserName> (UserName) </UserName>
<Password> (Password </Password>
</Login>
<Applications>

I have a list of names in a database and what i want is to get all of these names and display them in a label or a text box to the user on the website. I have tried to do this using a for loop but it is always overwriting the label each time. I have a list of 10 different names in the database and what it is doing is putting the first name in the label and then overwriting this with the second name and so on until it reaches the last name. I think i need to store each of the names from the database into an array or an arrayList and then make the label display all of the contents from the array or arrayList. The for loop i have used for this is:
Dim g As SQLadmin = New SQLadmin()
g.DB("SELECT nameOfPerson FROM Persons")
For i As Integer = 0 To g.array.GetLength(0) - 1
[code]....
i can select the names from the database and store them in an array then make the label display each of the names.

I am still having issues with the combo box. I have the correct query. I have four tables in MS Access. I need to create a form in Visual Basic that has a combo box and a datagrid. The selection from the combo box will display all relevant information about that person on the datagrid. For example, if I select John Doe (from the combo box) the datagrid should display: [Code] How do I add John Doe to the combo box and link this query to it, when upon being selected, it displays the result in the datagrid?

I have a program that needs to display a playlist of songs, for a band performing someplace, from a .txt file. The songs in the file are listed as follows:
All You Need is Love-Beatles
Rock
4.25
[code]....
The first line is the song's title and group name. The second is the songs genre. The third line is the songs length, 4.25 is 4 minutes and 25 seconds.upon clicking a button, I need to display a playlist from this .txt file based on the number of minutes the band has to play, minutes entered into a TextBox, and the songs genre, selected from a ComboBox. The songs cannot repeat and must be random.I have already coded the program to read the .txt file but have not clue where to start with the rest.

I have a form displayed where a user can can select a 'function' from a list box. That 'function' has a corresponding ID number which I need to be able to take and use later in the code.The List of functions is preset (about 150+ them and the IDs are already assigned (so I can't just use the index).So if the user selects "Function A", I need the code to set a variable to, for example "42" (or whatever that Funtion's ID is).
I was going to do this using listbox.item and listbox.itemData, but I'm using VB.Net in VS2008 and I understand that function is no longer present (to add ItemData at design time).Here's where it gets complicated. When the form loads it looks at the variable containing the FunctionID and if there is one present, I want it to populate the co-ordinating FunctionName. I can do that if I know the index number, but I don't know how to look at the FunctionID and return it's index (all FunctionIDs are unique).
A) store the info, either in the Listbox using ItemData, in an array (but I'd prefer to do it at design time), or some other way you might suggest.
B) cross-reference the ID and display the name in the listbox when the form loads.

I have a listbox where the user can add items to it with the following schema "count, id".I want to take each item from the listbox,use the split function so I can "take" only the "count," part and then add the "count," part of each item into a string.I mean I want something like this:
user adds 3 items in the listbox:
1, 100
2, 200 and
3, 300.
I want to make it,so a string can be formed, and contain the "count," part of each item which in this case is;
in the first item the "count," part is "1,",in the second item the "count," part is "2," and in the third it's "3,".I want those "count," parts to be stored into a string (which will result into having this string "1,2,3,").

I have been given the following piece of code which allows a checkbox selection to be made and an associated piece of text be printed in a textbox.
How would i be able to do exactly the same thing but for a listbox?
Also how would i be able to get something to clear from the listbox when then checkbox is unchecked without getting to complicated?

I've been making a scheduling program using the calendar object.I can manage to select any date with a single click with a message box pop up entering a memo for the date selected. After pressing ok, the memo is displayed in a list box, with date.
1.Unfortunately the date is being displayed twice - perhaps because i used .selectedrange in the handler ? i would like it to be listed only once
2. the memo comes up on a separate line, ideally id like it to be displayed on the same line as the date.i tried ListBox1.Items.Add(whendate, memo) but it cant compile, so ive had to put each line in seperately
3. I would like to mark the sundays and national holidays in red color (the calendar is only set for a year so i dont mind doing them by hand, however the only tool i can find in the Monthcalendar1 properties is MonthlyBoldedDates, and no color assignment [code]

I am doing a lab where you have to connect to the database using the Database Configuration Wizard in Visual Basic (Visual Studio 2008). The database connection is there since the form will display the records.The problem is the user is supposed to be able to click on the combobox arrow to select a stock rating (high, low, etc) and then the listbox will display only the stocks with that rating. I thought this would work but nothing is showing up in the listbox.
' strSql is a SQL statement which selects all the fields from the Team database.
Dim strSql As String = "SELECT * FROM Stocks"
'strPath provides the database type and path of the Team database[code]...

ive just registered but ive been reading this forum before.I have a medium problem and an easy problem.
My project adds dates in runtime to a listbox.It can be any date inputed by the user so theres no way to know which date is at which position thats why the listbox index stuff for me is totally useless.Problem 1: if lets say a user types in a date into a textbox "27-03-2001, and press an "OK" button, i want to select that date automatically in the listbox if it exists.the only way ive found so far to programatically select an item is to use the index stuff which as i said is worthless for my situation as the comparison is a string,So, how can i select an item from the listbox using a string to item comparison?
Problem 2: Dates in the listbox are dd-mm-yyyy format so they dont arrange properly, is there anyway i can make the listbox sort the items counting from right to left instead of left to right? because that would solve my problem as it would be like inverting the date itself while sorting.
if you can answear any of these 2 problems please dont hesitate to comment about it, if its possible or not and if it is how i can do it.Both problems are at the same importance for me

Basically I have a list box with a collection of strings. The way it works is you select an item from the list box then enter an integer into a text box and it calculates, straight forward.Where I'm getting tripped up is I'm trying to implement a 'Reset' button to reset the list box and text box. The text box is straight forward as is clearing the selection in the listbox:[code]I understand that since there is nothing selected the index is getting tripped up or whatever but I don't know how to stop this. I'm new to VB and programming in general and have been googling for days trying to get this fixed to no avail.

Just wondering if someone can at least point out where I'm going wrong here. I've already got the code to populate the listbox by a button click from the user and am just trying to figure out how exactly to alter the text of a label based on what the user selects in the listbox. From what I have the Label will display the case else selection but nothing else despite my best efforts to get it to change. Here is what I've tried. I realize it is very trivial, but I am only a beginner to programming.
