I'm using something call ultragrid in my program.The program works as a mini-record keeping area (Like any datagrid, really). Well, I am adding a history to it and it allows the user to see the last 50 records searched. They get a grid showing the records. This, thus far, works perfectly What I want to do is this: I want to select a record (A cell) in the column 'Dog and have the text of that cell appear in a textbox. This is what I've tried with no success.
HTML
Private Sub HistoryTextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles HistoryTextBox.TextChanged
If ugHistoryButton.ActiveRow.Cells("Dog").Selected = True Then
[code]....
It just doesn't seem to want to transfer over when I select the cell in the 'Dog' column.

I have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."
Private Sub dgvCalculatedResults_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles dgvCalculatedResults.MouseDown
Dim ht As DataGridView.HitTestInfo = Me.dgvCalculatedResults.HitTest(e.X, e.Y)

I'm using a search code using a textbox then it lists the record on a datagridview if search is successful. After the search, the user could select the record on the dgv in which later on can be edited or deleted. Edit and delete button is disabled when nothing is selected on the record. What I want to know is how to trigger an event to make those buttons to be enabled when a record is selected. By the way my datagridview is connected to my textboxes. My question goes something like this, but this is totally wrong.
dgvStud_CellClick = Nothing then
btnEdit.enabled = true
btnDelete.enabled = true
End If

Im having a little trouble setting focus on a row in a datagridview. When a user presses the Enter button in my datagrid, a sub is called and the window is closed. Now next time i display the window, the selected cell has moved one row down. This is because when you press enter in a datagridview it jumps to the next line (wich i really dont want it to do). Now then in my forms shown event i placed the code: Datagrid.rows(0).selected = True Now this highligts the first row when the window is displayed, but when you press the down key, it jumps to the third row, because even though the first row is highlighted, its the second row who has focus (because it jumped their after pressing the enter key) How can i set the focus on a specifik row in the datagridview in vb2005?

I'm looping through rows in a datagridview, and selecting a cell from the 3rd column each time:
Dim customer_name as String
For Each dgvr As DataGridViewRow In myDataGridView.Rows
customer_name= dgvr.Cells(2).Value
'....
next dgvr
However, I'd really like to make it dynamic, in case a new column gets added to the grid, so that I need the 4th column, not the 3rd. I'd like to use the column's header text. So something like...
customer_name= dgvr.Cells("Customer").value
Can this be done?

I want to be able to delete records from my database and have this piece of code to do so:
Dim myConnection As SqlConnection
Dim myCommand As SqlCommand
Dim ra As Integer
myConnection = New SqlConnection("connectionstring'")
myConnection.Open()
myCommand = New SqlCommand("DELETE FROM player_table WHERE player_ID = 1", myConnection)
ra = myCommand.ExecuteNonQuery()
MessageBox.Show("Player Deleted")
myConnection.Close()
But I want let the user actually select one of the cells displayed and delete that.

I am making a program which remembers my last selected row in a data table. I have done this by adding a column with a CheckBox, upon CellClick the CheckBox is checked, and upon ellLeave it is unchecked and the new cell is checked, after every action a Update command is run. There will never be more than one row with a checked cell in the DataGridView,however, the data table is in a relationship with other tables, so there may be more checked cells in the data table itself. My problem now is selecting the row with that cell when I open the program and when changing between other data tables and back again.All solutions I found on selecting a specific cell in a DataGridView are referring to index numbers, and in my case I need it to find a data value in a column, I do not know the specific row, only that one row contains the value of True while everything else is False.

The problem is when I search through a textbox and nothing matches the search query, I accidentally click the column header which is the lastname then the error "Object reference not set to an instance of an object." pops up.
The highlighted part of my code is the text closed in quotation marks.
"If dgvStud.CurrentCell.Selected = Nothing Then"
btnEdit.Enabled = False
btnDelete.Enabled = False
Exit Sub
Else
btnEdit.Enabled = True
btnDelete.Enabled = True
End If
This code is under my dgv cell click event. Here is a screenshot for the column header where I found the error. [URL]

How to select one cell and mulitple cells in a table using the webbrowser control. E.g. If the web page (local) that I'm viewing in the webbrowser control has tables present in it. When I click on a cell in the table I want to be able to edit the attributes of the cell like adding an align or a class attribute. I think this is possible without using mshtml which I'm trying to avoid as I can't find much user friendly documentation on it.
The text in the webbrowsercontrol is loaded with the foll:
WebBrowser1.DocumentText = Form1.RichTextBox1.Text
So I am guessing that I need to be able to detect when a cell is selected (<td></td> tag etc) or clicked on and then from that point I can edit the attributes of that specific cell (<td class="jimmy"></td> tag etc).

I want my code to do something that will require a bit of time. I want to be able to send an update to a label regarding the progress of the process during the length of the process, so that the user will know how far the progress has gone. Unfortunately, the label is only updated at the end of the process. I try to simulate it with a simple code below, where the label should be updated from 1 to 10, but it is only updated at 10, rather than 1, then 2, etc until 10. It does not help to show only the end!
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I have a form with a Tab Control that has 18 pages. When I click on a tab it opens the page and select a textbox on that page (txtTextbox1. Select() ). This works for the first 8 pages but not for the remaining 10 pages. Although on these pages I can mouse click on the textbox, enter info, save then click my Add button that clears the textboxes and has the code (txtTextbox1. Select() ). The textbox is selected just fine. The code for all my pages is the same except for the tab name and the control names. The tab key will move the selection to the next textbox in order on all pages and the Enter key is coded to do the same. The first 8 pages have a total of 256 labels, buttons, list boxes, textboxes and checkboxes on them.

I am trying to send keys to a control on my form. But I am getting a NullReferenceException and I don't know why. The code is about as basic as it gets: [Code] The error reported is object reference not set to an instance of an object but Send is a shared method so doesn't need an instance. Strangely if I ignore the error it works fine and F4 is passed to the control. I know there was an issue with sendkeys and UAC but I thought this had been solved (I am using 4.0 framework).

I have a datagrid control on my form that receives data from a device on the COM port. I strip out the data I need and put it into the currently selected cell. When I load the grid, I find the first empty cell and set the focus so each load presents the user with an empty cell to start receiving data. Once I get the measurement, I need to move to the next cell down (like hitting enter in the grid). This will allow the user to do measurements with the external device without having to move to the next cell.
