Sounds like a master-detail relationship?
How is the relationship defined?
Is the spelling correct on all column names? Need more info
Thanks,

I have one question:
In Help about odbcDataAdapter.Update Method is write text:
Calls the respective INSERT, UPDATE, or DELETE statements for each inserted, updated, or deleted row in the DataSet.
And when is calling SELECT statement?
I need sometimes calls on my odbcDA select command, which refresh my DataSet. Update can not I call, in my Table is not change, but in Dataset I take data from RelAted Table.

Update doesn't call a SELECT statement. It's used for UPDATING. All three SQL statements make changes, or UPDATE, the database.
When do you call the SELECT statement? Here's a hint: How did you fill your dataset in the first place?

You need to do OdbcDataAdapter.Fill(dataset)
This will use the select command to fill the dataset

Hi Folks,
I am looking for a free CTL or COM Control for XML Editing to use from VB6. Binary is okay - source might be nice.
Thanks

Download 101 VB.NET examples from msdn.microsoft.com. There is an example for sending email. You can see what to do from there.
Sounds like either your code is way off track or there is something wrong with the settings on the machine your code is running on.

As far as i know the smtp server needs to be the server of your service provider that you are connected with not your exchange server. For example if your internet access was with BT your smpt server would be something like smtp.btinternet.com otherwise you could easily spam from anyones email servers.

Can you create a VB6 program that does multi-tasking? I have to create a Printed Circuit Board test program that concurrently tests 2 boards. 
Thank you for your help in advance.

VB6 doesn't support multi-threading. It is possible to do, but you can't debug the code using the VB6 IDE. It'll crash the IDE when the code hits a breakpoint. Last time I searched for articles on VB6 multi-threading, I came up empty.
If you really want to do this, I suggest saving yourself the time and aggrevation and do in VB.NET or C#. At least in the .NET Framework, multi-threading is MUCH eaasier to code, debug, and support.

This can easily be done using an SQL statement, something like:
SELECT LAST(fieldname) AS LastProjectName FROM project_name;
This will return a single table, with one row under the column name "LastProjectName".

i find active window(FindWindow) using API. but i don't know how pass string (search word) to FindWindow's textbox? when it active. i am using sendmessagebystring API but it changes caption of active windos.
Any help appreciated
Thanks in advance
Private Declare Function GetForegroundWindow Lib "user32" () As Long
Private Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long
Public Declare Function SendMessageByString Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As String) As Long
Static lHwnd As Long
Dim lCurHwnd As Long
Dim sText As String * 255
Dim caption
lCurHwnd = GetForegroundWindow
If lCurHwnd = lHwnd Then Exit Sub
lHwnd = lCurHwnd
If lHwnd <> hwnd Then
caption = Left$(sText, GetWindowText(lHwnd, ByVal sText, 255))
Call SendMessageByString(lHwnd, WM_SETTEXT, 0&, ByVal "sample")
End If

You sent the SETTEXT message to the window, thereby changing the window title. You need to find the window that represents the textbox in that window, then send the message to that.

I have two date columns...StartDate & EndDate in my datagrid.
In my third column I need to display result of 'Start Date- End Date' in number of days
i.e. column3(no of days)=column2(enddate)-column1(startdate)
Using item template is one option but I cannot figure out how to subtract dates, calculate date and display in the subsequent item sell.
Any help anyone?got a deadline to meet 
(Language = Vb.net)
Many Thanks in advance.

When you subtract one datetime from another, the object that is returned is called a TimeSpan, as in
TimeSpan ts = endDate - startDate;
TimeSpan has a Days property.
