What your thinking of is an NDIS Intermediate Driver. These things slide in between the miniport and protocol drivers.
For original poster:
Docs on NDIS Intermediate drivers start here[^]. Your best best is to write the NDIS driver in C++. That'll save you time of recoding all of the structures, constants and function headers. You'll be doing this for about 3 dozen functions and structures. On top of that, you'll have a VERY difficult time debugging this thing unless your up to speed on debugging kernel mode drivers...

Almost, what I was thinking of was an NDIS Filter Hook Driver[^]

i cant understand you what are you saying, you mean that
i should NDIS hook , take its output to manipulate data field of TCP and then again pass this information to the driver? where should i write the code in vb.net which will do the work? is this or else?
can you briefly explain the steps involving in this thing?
and can you refer me some tutorials?
anyways thanks i seached on the google and found some sites on ndis.
waiting...

If you are not generating the packets in the first place then yes - The wording of your previous posts indicates that this is the case. If you are generating the packets there are easier solutions open to you.

It is not something that VB.NET can do by itself, you will need a third party piece of software. NTKernel[^] produce a product called WinPKFilter[^] which might suit your needs.
To connect it to VB.NET you will need to P/Invoke the functions that you are interested in.

The web site, has a forum for its products and demo software to show how to build applications using its components.

Packet capturing is not so simple that someone could explain everything about it here. It's just too big a topic. But there is a couple of articles on it here[^] and here[^] on CodeProject. There are also some packet capture libraries out there like this one[^]. It amazing what you can find with a Google search on "source code packet capture"!

Hi. I'm a newbie programmer so my problem probably have an easy solution.
Here's the code that adds items to my ComboBox:
*****************************************************'
Sub loadTypCombo()
Dim recset As New ADODB.Recordset
Dim conn As ADODB.Connection
Set conn = loadDatabase(CommonDialog1.FileName)
recset.CursorType = adOpenDynamic
recset.LockType = adLockOptimistic
Set recset.ActiveConnection = conn
recset.Open "SELECT * FROM tblObjects ORDER BY Name"
While Not recset.EOF
TypCombo.AddItem (recset("name"))
recset.MoveNext
Wend
recset.Close
Set recset = Nothing
conn.Close
Set conn = Nothing
End Sub
******************************************************
The problem I have is when I run the program only 4 of the 5 records in tblObjects are added to my ComboBox, however, when I debug all 5 are added and it works like it's supposed to.
How can I fix this?
Thanks in advance, Rikard

i have a form allows me to add, edit, delete records, and also see the master list of my records, this form has a dataset and a winsock-like object (private withevents) this application is connected to a server using my winsock-like object
what it does is that everytime i click on add or edit, a new form is instantiated and the record which i want to edit from the previous form is loaded in this new form (in the case of add, no data is loaded on the form) after adding or making the changes, the new form calls the add record method / edit record method to...
1. update the changes to the database
2. pass the new data to the server using my winsock-like object
after executing, the new form closes itself. i don't have any problems with updating changes to the database, but when i try to send the new data thru my winsock-like object, it gives me a "object reference not set..." error where in fact i clearly created a new instance of my winsock class when the form was loaded and the connection is still alive between my application and the server, should i change the modifier of my winsock-like object from private to shared or protected? please tell me what went wrong, thanks
|

|

It's definately not a modifier problem. You'll have to supply some code and the exact error message and the line it shows up on. It could also be that the problem is in your "winsock-like" object. Is your object throwing the exception and your main code catching and not handling it?

|

thanks anyway, it's already working, i realized that i instantiated the winsock object during "form load" and not inside the form's constructor

How do you pull data from a database and set them as columnheader in listview or a datagrid?
|
|
|
|
|
Are you using a stored procedure?
Give more info about your requirements...

The list view will be controlled by a date or calendar control. Haven’t decided whether to use a stored procedure. Since I use a select statement with a case argument. Still not getting the look I want.
It would be similar to a cross tab table used in ms access.

Hey Ole123
Well I will leave the front end to you, but if you choose to go with a stored proc then here is the basic layout including getting the headers...
CREATE PROCEDURE MP_CB_Get_CallBacks
AS
-- V1.0.0 : Super Winsock : 4 March 2002
-- Returns the Column names and width for the grid.
-- It also returns the data.
SET NOCOUNT ON
--Returns the Column names and it's width.
-- 1st is the column name & 2nd is the column width and so on.
SELECT
'Id',
0,
'Student_Name',
0,
'Teacher_Name',
2000,
'Subject',
1500,
'Time',
1500,
'Date',
1500
SELECT
[Id],
Student_Name,
Teacher_Name,
Subject,
Time,
Date
FROM
?Table
SET NOCOUNT OFF
GO
/* Hope this helps?
|
|
|
|
|
I forgot to add that the student data is a seperate table as well as the teacher's data. So I have a Student and Teacher table. I don't think I could use a stored procedure.
|
|
|
|
|
Well thats no problem?? Just use a JOIN statement to join the teacher and Student tables... This can be done in a sproc.
If you really get stuck, just post the Student and Teacher Tables structures and what you want to get out of them in your record set, and I will gladly help you write the sproc.

Still a little stuck so i still need help. I posted a sample tables in the post and what the display should look like...
Thanks for all your help. I have been kicking my self for about two weeks trying to get the display i want with no success.
MSSql does not use the Transform sytnax so i'm not able to create the crosstab look and feel for my listview form in vb.net.
Thanks again for all your help

Hey Ole
Well your post of the tables is somewhat confusing
Teachers |Prof. Clark | Prof. Brooke | Prof. Daniels
___________________________________________
Time

9:00 |James Keith | Blank|Blank
etc...
1.Are your headers always going to be the same? If so then you can just hard code them.
2. Just tell me what the headers are and from there I can get the info from the tables.
3. In a listbox you have to use COURIER NEW as your font, else the spacing is never going to be right.
4. You have to pre-determine your column lengths before you populate the listbox. IE: If you have a column named First_Name, thats 10 characters, and the name is Ole. You will have to add 7 spaces after the name to make the next column's data in line with its header.
Probably a bit confusing the way I explained but just tell me the column headers and I will write the sproc. Thats the easy part.
You will have to do the front end.

The columnheader will always change. So it's more of a dynamic columnheader. Depending on the Day of the week. There could be 5 or 3 or 10 teacher who have classes to teacher at different time of the day.
The Teacher's name will be the columnheader
Basically i'm trying to build a cross-tab query
Teaher's names across the top
The time is in the left column down
and student name
Teacher_Name Teacher_Name Teacher_Name Teacher_Name
Time Student_Name Student_Name Student_Name Student_Name
C1 and R2 = Student_Name C2 and R2 = Student_Name
C1 and R3 = Student_Name C1 and R3 = Student_Name and so on
The only way i can build a cross-tab query is in crystal report.
