I am looking at Visual Basic 2008 Step By Step. I need to read a flat file and insert the records into my SQL database. My code so far:

The INPUT line needs to be fixed. From what I can see, I need to move it all to a single field and use a split to parse it, correct? As I look at the entries on this site, all the code seems to use stream readers. Why would the book not do that? Am I missing something?

I am trying to count the number of records that match Course_ID = 1 in a table.
Here is the expression I am using
=Count(IIF(Fields!Course_ID.Value="1",1,0))
also
=Count(IIF(Fields!Course_ID.Value=1,1,0))
I always get the number of records in the whole table and that is not what I want.

When the query is executed the first pass the record count is 19.This is valid and matches the DB The 2nd pass the record count is 49, but the DB only shows 30.

I'm having a problem setting the maximum number of records that can be saved into Access. The maximum allowance is to be 10. Records are being pulled from a listbox. The whole problem is that if the listbox has 7 items and my table already has 5 records, it still records them, making a total of 12. What I'm looking for is a way to trap that to a max of 10.[code]...

I have used VB6 for all kinds of database programming. Now I am fairly new to the vb.net. How do we read the records (rows) from a dataset and manipulate data? I want to populate a combobox or a datagrid with a recordset (in VB6 language). What is the .net equivalent of ado dataset, and how do I use it. I have tried several ways using dataadapters and dataset, etc.

I have a datagridview that is bound to a dataset by dragging it onto a windows form. I want one of the columns on the datagridview to be read only for existing records (rows), but I don't want it read only when the add new icon is pressed on the navigator. How can I tell when a row is being edited as opposed to being added?

I am trying to display the content of the text box according the number of records in the database. When i do it manually it works but when i do it through the "for" loop i am confused. my code is as below
For i = 0 To total_rec
fname1.Text = ds.Tables("roster").Rows(total_rec).Item("FirstName")
lname1.Text = ds.Tables("roster").Rows(total_rec).Item("LastName")
Next
Now i want to change the index of "fname1" some thing like "fname(total_rec)" but it does not work

I'm creating a report where I want to send a parameter for the number of records to display (I do not want to select the number of records in SQL) I have created a parameter field (?topN) and set the group to use this value which in design mode works well however when I try to set this parameter in vb.net code it does not work. The field which also displays the value shows the parameter correctly though.
