Most DGV are populated by binding them to an underlying list (List<t> or data table/view) you could add an extra column to the list and populate that column with the results of your function.
How are you populating your DGV.

Thank you. In fact that is just what I ended up doing, on the fly so to speak.

Use the following code as a starting point ...
totalrows = ActiveSheet.UsedRange.Rows.Count
For i = 1 To totalrows
MsgBox(Sheets("Sheet1").Cells(i, 6))
Next i

You need to modify a little, the code snippet that David Mujica gave you
Something like that:
totalrows = ActiveSheet.UsedRange.Rows.Count
For i = 1 To totalrows
'MsgBox(Sheets("Sheet1").Cells(i, 6))
Sheets("Sheet2").Cells(i, 6)=Sheets("Sheet1").Cells(i, 6)
'or whatever
Next i

please tel me how i can make four image with x,y resolution , from the input pic of x*2,y*2 image resolution , so if we consider the input image in four pixel squares (two pixel width and two pixe height) the first of output use the first left pixel of four pixel in the square and the second picture use the right top pixel , third use the bottom right, and the fourth use the left bottom ,
i use the setpixel and getpixel method for it, but it is too slow , i think if i use method of changing the image to array it will be very faster, please tel me ho i use the array method.
this is my code in vb.net but too slow :
For y = 0 To picy.Height - 1 Step 2
j = Int(y / 2)
For x = 0 To picy.Width - 1 Step 2
i = Int(x / 2)
pic(0).SetPixel(i, j, picy.GetPixel(x, y))
pic(1).SetPixel(i, j, picy.GetPixel(x + 1, y))
pic(2).SetPixel(i, j, picy.GetPixel(x + 1, y + 1))
pic(3).SetPixel(i, j, picy.GetPixel(x, y + 1))
Next x
Next y
best regards

Read my articles on image processing. You will need to use C#.

Hi,
if all you need the new image for is showing it on screen, you should not spend any time creating such image, just consider using a Graphics.DrawImage with InterpolationMode.NearestNeighbor
to get it completely correct you probably also have to perform a Graphics.Translate() over half a pixel in both x and y!

I'm not sure what his ultimate purpose is, but it looks like a pixelating viewer, maybe an editor.

this code used for generating four picture from input one, in half resolution of the source image.
this applied to print machines , in micromovement technology for decreasing the print resolution in the paper exposing of the digital printing machines.
it may be used in 9 from one or 16 from one picture.

Hi,

Can you please respond quicky?

No.
I don't get why people say stuff like that. We're not hired to do your job, we do it for free. You can't give us deadlines on that.
It's just data, did you bother to try storing it and retrieving it, before asking this question ? Why on earth would storing and retrieving it cause the formatting to change ?

Sory about that
I tried it but an error appeared during loading saying type byte cannot convert to string. I dont know what to do next. i already stored the content of the rich text box
this is the full code
<br />
<br />
<br />
Private Sub frmTest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
conn = New MySqlConnection()<br />
'connection <br />
myConnString = "connection to server" <br />
conn.ConnectionString = myConnString<br />
conn.Open()<br />
If conn.State = ConnectionState.Closed Then conn.Open()<br />
massDataTable.Clear()<br />
massCommand = New MySqlCommand<br />
massCommand = conn.CreateCommand<br />
massCommand.CommandText = "SELECT * FROM `test` where `mark-1` = 1"<br />
massAdapter.SelectCommand = massCommand<br />
massAdapter.Fill(massDataTable)<br />
With Me<br />
.RichTextBox1.Text = (massDataTable.Rows(0)(1))<br />
End With<br />
End Sub<br />
<br />

So the correct question is, how do I store a byte[] or how do I convert that to a string, surely ?

If you're a beginner, then perhaps this task is too complex for you. Perhaps you shouldn't be doing paid work at all.

Hi,
what you need to save and restore is RichTextBox.Rtf not RichTextBox.Text
Rtf is text+markup; Text is just text.
BTW: why do you choose database field names containing strange characters, as in mark-1? it only makes life difficult without any benefit for anyone.

Before, i use textbox with multiple lines, but my coleauges say they need to do some formating (such as a italicalize headings and underline text and a dozen paragraph), so i use a rich textbox
I name the database field name so it will be easy to remember, but this is just temporary.

Somehow I think you missed my first point entirely. Anyway look here[^].

As Luc said, the reason why the formatting isn't preserved is probably because you're storing the string your getting from the RTB's Text property, when you should be storing the RTB's RTF property instead.
