Re: How to Retrieve TCP/UDP Statistics using System.Net.NetworkInformation

The stats you want are not kept in those classes, nor are they, if my research is correct, kept in the underlying network layers. I think you may be forced to write your own packet filter and generate these stats yourself by inspecting individual packets.

Not really. But you can start by Googling for "WinPCap".

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.

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. Smile | :)

ocx question

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

DBNull... why doesn't this work?!?!?!! ( IIF )

Jacob Dixon26-Jul-09 10:18

26-Jul-09 10:18

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)

value Is DbNull
value Is DbNull.Value

value is typeof(DbNull)

Its just frustating.. am I doing something wrong here or is this just a flaw?

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"
