View 12 RepliesI am creating a word document which has a table in the header. I want to add a Page x of Y autotext into one of the cells but no matter what I try I cannot seem to work out the syntax.
I tried (among other things)
tblTable.Cell(3, 8).Range.Select()
oWord.NormalTemplate.AutoTextEntries("Page X of Y").Insert(Where:=oWord.Selection.Range)
I'm trying to get the AutoID after inserting a record in to a DB. Does this code look right as Mydata is blank afterwards?

i'm importing a text file into a access table like this:
vb.net
sql.CommandText = "SELECT * INTO [tblMailList] FROM [Text;DATABASE=" & frmMain.FolderName & ";HDR=NO].[" & frmMain.TextBoxFileName.Text & "]"
sql.ExecuteNonQuery()
my question is what is the best way to add an autonumber to the table? i currently do it like this:
vb.net
sql.CommandText = "ALTER TABLE [tblMailList] ADD COLUMN [ID] AUTOINCREMENT;"
sql.ExecuteNonQuery()
but when the file is too large i get this error: "File sharing lock count exceeded. Increase MaxLocksPerFile registry entry."

vb.net
My.Computer.Registry.SetValue("HKEY_LOCAL_MACHINESOFTWAREMicrosoftJet4.0EnginesJet 4.0", "MaxLocksPerFile", "9000000")

I have 4 Columns in a ListView. The first one is called Serial No. Every time I populate it, the serial number increases automatically. After populating the ListView couple of times, I select any row(s) and remove it. When I remove one or more row(s) from the listview, serial numbers stays same. I want the serial numbers to be fixed automatically when I remove any number of row(s). How can I do that ??? Here is my code -

Probably a simple question for most of you. I'm putting members of a group into a SQL Database so we can better manage attendance and 'points' that they earn for doing work. I've written the program in VB and have the SQL server running fine. However, I have created a separate table to handle the points and have marked the relationship between the table - the column is named 'PointID', and should be unique for each person. When I add a new user to the database, I want it to automatically assign a value to that without me having to do anything extra beyond pressing save. From this PointID, it should identify the user and it will bring up the person's points.

I want to write the code not use the autonumber in Access as my lecturer does not want me to do it this way
I am building an application in VB that will use a JetDB backend (Access 2007 db). I am trying to figure out how to capture the autonumber PK from the database when I add a new row to the table so that I can then load that value into a variable. I am currently using the IDE tools for my database queries (dataset designer), so if this is not something that can be done through that, I would need to know how to code my database query.
Here is what I have:
Table (mainTable):
ID (autonumber PK)

I have created a field which automatically in sql server.I want a code in vb.net so that user the text on the get focus, the automber would display the current no on the form.This autonumber is primary key in table1(tran_head) and as foreign key in table2(trans_Detail).I want another so that when the data is saved, it would automatially update the second table with current automber displayed.
