How to programmatically change foreground color and make bold text in individual cell location on DataGridView control (Visual Basic)?
I use "dgMatrix.Rows(r).Cells(c).Value = x" to assign individual numeric values to individual cells in a DataGridView control. My question; is there a similar way to change foreground color and make bold the text in this cell, by specifying the individual row/column cell location?
For example; for cell (row 3, col 5) in the DataGridView make text in cell say red and bold or blue and bold so as to highlight and distinguish individual cell contents. As needed, I will also need to reset these properties (foreground back to automatic/black and font from bold back to regular); the reset could be done globally to the whole DataGridView as opposed to indiviaually by cell.

I'm using Visual Basic 2008 Express Edition, so I have a combobox that gets filled with items from a data base made with Microsoft Acces, the combobox is filled with the values stored in a column from a table in de database so the user can select an "option" from it, I want to add labels that show the values for the corresponding row of that column. I used the Data Source panel to drag and drop the labels corresponding to the values that I want and it works it show the value that I want when I compile the application (at least I think it does, it could be that it's only selecting the first entry) the problem is that when I select a diferent entry on the combobox the labels don't refresh with the new values. How can I do that?
edit
how does Visual Basic Populates de combobox and gets the value of the other Acces DB entrys to change the .text value of the labels? And I mean the actual code that does that.

For my application i'm trying to generate a datagridview with a comboboxcolumn in it. This combobox I wanna fill with some data from a table in my database.I've figured out how to add items to the combobox but I can't assign a value to it. The combobox is suposed to fill with product name items, and the value should be the weight of the product, so later on i can calculate the total weight.But now it's just displaying the product name, and the value is also the product name.
Dim palletds As New DataSet
Dim palletsql As String

How do you change the column type in a datagridview programmatically? I have several tables that I want to allow the user to update using the same form. Depending on the table, I need to change the column type to a checkbox instead of text. Following is the code that I run (just exchanging the table name and column #). Everything works well as long as I don't try to change the column type.
Dim qry = From lst In dbCodes.Codes_InjuryBodyParts _
Select lst Order By lst.CodeDisplay
Me.bsCodes.DataSource = qry

I have a combo box which will store a list of RGB values generated when the user makes a custom color in the color dialog. The values are stored in the combo box in RRR, GGG, BBB format. I have this working. The code for this is as follows:
dlgChooser.ShowDialog()
Dim colorR As String = dlgChooser.Color.R.ToString()
Dim colorG As String = dlgChooser.Color.G.ToString()
Dim colorB As String = dlgChooser.Color.B.ToString()
lblTitle.ForeColor = dlgChooser.Color()
cmbRecent.Items.Insert(0, colorR & ", " & colorG & ", " & colorB)
cmbRecent.SelectedIndex = 0
The next part is to change each recent color's background color to match whatever color the values represent (so that it's easier to pick from the colors). How do I assign a background color to each item listed in the combo box?

I have a DataGridView control with two columns:
colName
colAnnounceURL
I also have a ComboBox that I need to bind to the colAnnounceURL in the DataGridView. So everytime I add new rows to the DataGridView, the ComboBox will be updated with the items in colAnnounceURL.
I have tried the following to no avail:
cboAnnounceURL.DataSource = dgvTrackers
cboAnnounceURL.DisplayMember = "colName"
cboAnnounceURL.ValueMember = "colAnnounceURL"
The code does not cause a crash but does nothing.
Both controls are visible to the user. The idea is to have DataGridView act as AnnounceURLs manager and ComboBox to set the active AnnounceURL.

I have a checkboxlist that is filled with items from an array. I want the user to be able to select the items they want to remove then press a button and have the items be removed from the array. I have never worked with a checkboxlist before so I'm not really sure how to go about this. Here is what I have tried so far:

When I re-display the array into the checkboxlist it shows that nothing was removed from the array.

My.Settings.Current_DB is bound to 'cbdatabase' which is a combobox which is filled by this method:
me.cbdatabase.datasource = (From foulder in New IO.DirectoryInfo("" & Application.StartUpPath & "Database").GetDirectories Select (folder.Name)).ToArray I am using the My.Settings.Current_DB to keep track of the current database being used by the client. So that throughout the program and when the program starts up it knows what the current database is.
The databases and the folders have the same name, in order to keep track of. My problem is when the combobox is filled when the program starts, it is overwriting the current info with the first item of the info loaded into the combo box.
[Code]...
Instead of maintaining the Current_DB as "Default", it updates it with the first item into the Combobox and that is "Alabama". How do I fix this so that it maintains the correct Current_DB and not update when the Combobox is filled.

I'd like to allow the user to select up to an entire column of cells and type and/or paste a single value that would then change the value of all the selected cells in the DataGridView to the value that was typed or pasted. I understand this is probably two separate answers, but perhaps if there is a way to set the contents of the clipboard with the value typed, I was thinking it may work well to identify both things I want to do.
