Display Information In A Listbox From Selection Made In Datagridview?
Jun 26, 2009
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?

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 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 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]...

I have been searching a lot online but couldn't find a solution for my problem. I want it to refresh every certain interval of time without this message to display. Now Ican't minimize my program because I'm putting an automatic Sendkeys.send("{Enter}") after the refresh to get rid of that message by clicking on "Retry".And If I minimize it the Enter will be executed on the active Window, which might be any other Window.
I hope that you understand what I mean, If not, I will clarify more.

If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ListBox1.Visible = False
ListBox1.IntegralHeight = True

I am currently working on a school database that I am having troubles with. I have the Table Adapters, Binding Source, and DataGridView all working, along with the Insert, Update and Delete Commands. I have the user open up the SubjectForm. On this form the user is looking at a DataGridView of the subjects table and everything that is in it. When the user clicks add new on the right side, it opens up a new form called AddNewSubject. When the user gets done adding the new subject in, a dialog box appears and says that the subject was added successfully. After the user clicks exit, it takes them right back to the SubjectForm where the DataGridView is. My question is, how do I update the data in that grid so that after the user clicks exit on the AddSubject Form, the new data will appear in the grid? I have tried a combination of things and they haven't worked. I will add my code at the bottom.[code]....

I am trying to open a .csv file via openfiledialog and then display information on a datagridview...What would be some ways to approach this? I have tried reading the file, separating the values by commas and placing them in a string followed by placing the string into a list. I place them in a list because I have more than one string of text I want operated in the CSV file. How can I display each string of separated values onto my datagridview?

I have a relatively simple application that uses a series of combo boxes to ask questions. These combo boxes are bound to a table with 2 columns in it "RSN" and "RSN_ID". I'm using one table adapter to feed the form (and these boxes) once the main form is loaded. The problem I'm having is when I change one of the boxes, they all change to the same value, almost like they have the exact data source (which they do) but shouldn't you be able to make different selections even using the same table adapter? I have to run 20 queries at loadtime, or create 20 table adapters.
My current setup is like this:
Data Source: table that feeds the combobox
Display Member: RSN (from combo box table)
Value Member: RSN_ID(from combo box table)
Selected Value: Form's main binding source, unique to each combo box, where the selection is actually saved.
This works perfect when using one combobox, but as soon as I bound all of them I ran across this...

I am trying to create a dynamic dropdown after a dropdown has been selested (in asp.net vb)
For example: I have a dropdown question that asks: What brand of car do you drive (Toyota, Ford, Honda, Nissan, Chevrolet)
When the brand is selected I want another dropdown to appear under it with new chocies
For example: If Nissan is chosen, the second dropdown will be populated (from the database) with (Altima, Maxima, etc...)
And in some cases I would like a text box to appear, but If I can figure out the dropdown portion, I am sure I can figure out the textbox.

I have a DGV with a CB column in VS2008. I would like an event when a DGVCB selection is made (without leaving the cell). It will probably have to be a DGV cell or row event but I can't find one that fires as soon as a DGVCB selection is made.

I am a new student of Visual Basic. I am using Vis. Studio 2010. Is there some sample VB code that I can gain access to that shows how to test on multiple selections that were selected within a listbox using the "For each" construct? In this scenario, multiple items have been selected but not 100% of them. I need to know how to test on which ones are selected as I examine each one in the list using the "For each" construct.

I am working on a text-based game and as your character moves, you get informations such as the room name and below, a description (Lorem ipsum in the example) which is an array of string. I would like to know how to append characters to it. I am actually trying to display a minimap made of ASCII character. See the second bloc code for an example.
From:
code:
Into:
Room Name Here
code;
The game itself is made in VB.NET but a solution in pseudo-code is also welcomed. Also, each line's length is aproximatively the maximum length it must be.
The desired output must be an array of strings because this data is later send to a client connected using sockets.

I have a DGV bound to a data adapter. I have a button that loads a form with a reference to the DGV row. When the form is loaded, it has a TextBox to type a value, that modifies one of the cells of the row. When the form closes, the cell.value is properly modified, but saving the DGV doesn't save the new value of the cell to the DB table. I'm assuming this happens because the DGV hasn't had physical interaction. Also, this particular field is a password field, so the whole column is being hidden from the view.It seems that a DGV change is noted by physically clicking in a cell and it stores some data telling the adapter there have been changes. The thing is, this is done on a per cell basis, and only if the cell has been clicked. Well, this cell is hidden, so even though the value will be changed, you could never click or select that cell.Is there any other way to force the DGV to accept changes made to it from outside actions of just assigning the cell.value from a button click and not phsyically changing it in the DGV?
