how could an image be captured from an avi file in vb.net?

There is at least one article on this site that uses the DirectShow wrapper to do it in C#. you could use the DLL and call it from VB.

hello all,
I have a data grid in vb.net 2003 connected to the database
what I need is to select specific data by choosing the employeeID using comboBox
e.g: comboBox: a.srour
datagrid: view a.srour details ....
|
|
|
|
|
There are definately articles on the site for putting a combo box inside a data grid.

thank u Christian Graus, but what i want that the combobox outside the datagrid, it is a kind of filter.
select a value from comboBox for its details to be viewed in the datagrid

Oh, OK. That's even easier. You just handle the index changed event on the combo, and run fresh SQL to fill the grid based on the selection. The combobox lets you store a value that's associated with each string entry, so you can hide the Id you need in there.

To be honest, I can't. How are you accessing your database ? What sort of database is it ? What value do you want to use to select your values ? What is your database schema ? I can't provide more direct help without all of that info, and if you can't do it, I'm wondering which bit you're stuck on ? Can you access your database at all ?

''The SQL select Command
Private Sub conn()
dt = ProfileDAO.ExecuteStrDt("SELECT [ComputerName], [Comming], [Leaving], [TotalTime], [IncludeTotalTime], [OverTime],[overtimeckh] FROM [HR].[dbo].[WorkingHours] )
DGtimeS.DataSource = dt
End Sub
' I am Accessing the db without problems
' the comboBox is also connected to db and retriving data without problems
Private Sub ttt1()

With CmbEmployees
For i = 0 To dt.Rows.Count - 1
FullName1 = dt.Rows(i)(1) & " " & dt.Rows(i)(2) & " " & dt.Rows(i)(3)
.Items.Add(New Mylist(FullName1, dt.Rows(i)(0)))
Next
End With
End Sub
'what i want is to connect the combo box and the data grid
'vb 2003 & sql 2000
is that possible
& if u give me ur email i may send u code of the app

OK, so you have the employee Id in your combobox item. Now, pull it out of there when a selection is made, and write your SQL with a where clause that uses this Id to get only the data you need, and bind it to your grid.

TWo things
1 - no way do I give out my email address
2 - I cannot give you exact syntax. Like I told you, unless I see the schema of the DB, I don't know what it is. Why can't you work out the syntax ? Is it the SQL that you have trouble with ? b/c the data access code doesn't really change.

Microsoft have an Office toolkit you can install to control later versions of Office with .NET code. Your code will only work on machines that have office installed.

Thanx,but I want to know how vb.net to do it not with office toolkit?

OK, then the answer is you really can't, not unless you write a program that is fully able to read the XLS file format. Unless you work only with the new Office 2007 format, which is just a zip full of XML, I'm sure that's easy to add to.

i need a way to deal with a number that is 320 digits long. Whats more, it needs to be an integer, not a decimal. how would i go about working with such large numbers, dividing, adding subtracting, etc. I have tried Long, Decimal and Double but none of them are long enough.

There is no type that handles numbers remotely that long. You'd have to write your own class, to handle a type like this, or look for one online. Do you need all 320 digits to be accurate ? If you only need accuracy to a certain number of digits, you can always assume the rest are 0s.
