I have to admit, if you were offering a cash prize, I might be motivated to guess, but right now I have no idea what the hell you're asking for, except that you're in the wrong forum, as this appears to be an ASP.NET question.

Hello Experts,
I want a code that will focus to the first cell of grid from it's last cell.
I had used following code,it works for other grid but not work for one of the grid which has combobox in it's last cell.
DatagridView1.ClearSelection()
please help me.
Thanking You,

You could try something like
DataGridView1.CurrentCell() = DataGridView1.Rows(0).Cells(0)
' you might also have to add, depending on size/number of rows/columns
DataGridView1.FirstDisplayedCell() = DataGridView1.Rows(0).Cells(0)
I haven't tested it, but it should work.

There's a task scheduler in windows, I believe. Or you can write a service which launches your app.

Well, gee, there's a tidbit that might have been worth mentioning. In that case, I have no idea, beyond that you'd use the Microsoft Tools for Office. Perhaps you should modify your subject line so it actually relates to the question, and so you might attract the attention of someone who knows the answer.

Hi, relatively new to vb
trying to get various parts of a db into an array
all examples so far are a bit too vague for me to follow
what i need is a more detailed (ie tutorial) example of how to
i so far have an array of strings and am trying to get items in a db to populate said array
any links to tutorials or good examples in vb .net would be much appreciated

You would fill a data table from your database, then iterate over it using the Rows property, and then pull out the strings from each row to fill your array.

what is the coding i would use? i have infact no relevant code for this module of my program, thus haven't supplied any
ive been struggling for a while now
array(1) = me.dataset1.table("",x,y) - where x and y are rows and columns
is there something similar / what do i have to do to make this work?
do remember that i am new to vb and programming in general

You will get all the examples that you need if you search MSDN for the terms that Christian mentions.
1) fill a data table
2) iterate the Rows property
doing it this way will also help you to remember how to do it (at least it does for me), with the added benefit that you discover additional stuff along the way.

Hi, All
Is there any way to decompile a .ocx file which is compiled by VB6.0? If not, is there any way to extract the files that this ocx is composed of? that is to say, if the ocx file contains some .frm files, some .bas files and so on, can we extract these from the one ocx file?
Thanks
Best regards
Wei

I cannot figure out why this doesn't work. Everythign says it should... I'm trying to see if a datagridviewrow contains DBNUll
'first = IIf(TypeOf _row.Cells(1).Value Is DBNull, 0, CDec(_row.Cells(1).Value))
'second = IIf(TypeOf _row.Cells(2).Value Is DBNull, 0, CDec(_row.Cells(2).Value))
'final = IIf(TypeOf _row.Cells(3).Value Is DBNull, 0, CDec(_row.Cells(3).Value))
I GET ERRORS!!!
But if I do this, not only is it ugly as heck but it works!!
If (TypeOf _row.Cells(1).Value Is DBNull) Then
first = 0
Else
first = _row.Cells(1).Value
End If
If (TypeOf _row.Cells(2).Value Is DBNull) Then
second = 0
Else
second = _row.Cells(2).Value
End If
If (TypeOf _row.Cells(3).Value Is DBNull) Then
final = 0
Else
final = _row.Cells(3).Value
End If
Why?!?! I'm so angry. I have tried everything from
IsDBNull(value)
to
value Is DbNull
value Is DbNull.Value
to
value is typeof(DbNull)
Its just frustating.. am I doing something wrong here or is this just a flaw?

Yah I knew I used it somewhere, try
mvLogID = IIf(IsDBNull(oRow("LogID")), 0, oRow("LogID"))

No luck. I'm not trying to find if a row is null, just if a cell is null
first = IIf(IsDBNull(_row.Cells(1)), 0, CDec(_row.Cells(1).Value))
second = IIf(IsDBNull(_row.Cells(2)), 0, CDec(_row.Cells(2).Value))
final = IIf(IsDBNull(_row.Cells(3)), 0, CDec(_row.Cells(3).Value))
Using the name instead of the index doesn't work either.
Still get "Conversion from DBNull to type Decimal is not valid"

Can I have my foot back now please  I was testing against a DATAROW.
Try, you are testing the cell, it will always be there. And here is your foot 
first = IIf(IsDBNull(_row.Cells(1).Value), 0, CDec(_row.Cells(1).Value))

Still no luck though. Here it is:
(All of it)
For Each _row As DataGridViewRow In dgvGrades.Rows
Dim first, second, final As Decimal
' ********* This doesnt not seem to work but technically it should **************
' ********* Must be a FLAW in VB.net :-) lol ************
'first = IIf(TypeOf _row.Cells(1).Value Is DBNull, 0, CDec(_row.Cells(1).Value))
'second = IIf(TypeOf _row.Cells(2).Value Is DBNull, 0, CDec(_row.Cells(2).Value))
'final = IIf(TypeOf _row.Cells(3).Value Is DBNull, 0, CDec(_row.Cells(3).Value))
first = IIf(IsDBNull(_row.Cells(1).Value), 0, CDec(_row.Cells(1).Value))
second = IIf(IsDBNull(_row.Cells(2).Value), 0, CDec(_row.Cells(2).Value))
final = IIf(IsDBNull(_row.Cells(2).Value), 0, CDec(_row.Cells(3).Value))
Dim _average As Decimal = (first + second + 2 * final) / 4
For Each _sRow As DataGridViewRow In dgvStudents.Rows
If _row.Cells(0).Value Is Nothing Then
Exit For
Else
If _row.Cells(0).Value = _sRow.Cells(0).Value Then
dgvAverage.Rows.Add(New Object() {_sRow.Cells(2).Value.ToString() + " " + _sRow.Cells(1).Value.ToString(), _average.ToString(), CalculateGrade(_average), IIf(_average > 59, True, False)})
Exit For
End If
End If
Next
Next
The funny thing is (well not so funny) is that I can do this:
If IsDBNull(_row.Cells(1).Value) Then
MessageBox.Show("IT IS NULL!")
End If
AND IT WORKS! its the same thing!

you said "you get errors". what error are you getting?
btw...not sure if you meant to do this but you are testing cell 2 again and then useing cell 3
final = IIf(IsDBNull(_row.Cells(2).Value), 0, CDec(_row.Cells(3).Value))

The error is it can't convert dbnull to decimal. It shouldn't be trying because it's supposed to make it 0 if it was dbnull. Yeah I didn't mean to do that I just changed it so much trying to get it to work I messed that up

I have seen that somestimes checking for dbnull in an IIF doesn't always work. try breaking it out into a normal IF/Else statement.
