I created a access table with three fields, CustomerID, FirstName, LastNameI set the CustomerID field to the primary key and the type of AutonumberIn my VB app I dragged the three fields over to my form.I clicked on the plus sign at the top and it displayed -1 in the customer field, I entered a First Name and a Last Name and press the save button. I repeated the process 2 more times and the CustomerID field went from -2 to -3.I looked at my table in acces and all three records showed 1, 2 & 3 as it should. When I exited the form and then open the form again it shows record numbers 1, 2 & 3 as it should.How come it takes exiting the form and then back in to see the correct CustomerID's ?

View 2 RepliesWhat I'm attempting to do is create a Form with two Panels:
Left - A autosizing panel with a dock fill richtextbox
Right - A constant size panel with buttons and features for editing the text
Effect desired: When scaling the size of the form you cannot scale smaller than the initial size of the form, but when expanding the panel on the right is anchored to top right while the richtextbox in the left panel will scale infinitely in either height or width dimensions.
I am sure this is likely some simple property of the textbox or the panel, but cannot seem to locate it. I have the panel on the right anchored at constant size, but cannot seem to get the panel left to autoscale on dimension change.
I have a richtextbox that I paste a HL7 msg into and then harvest the message instance manually from the text, what I would like to do is automate the harvest of this integer to automate the selection process.
example of message:
OBX|1|TX|^13971.8498.Report Text||Examination: Right elbow series
OBX|2|TX|^13971.8498.Report Text

View 7 Repliesi'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."
and yes, i have tried to change the registry entry and it didn't work:
vb.net
My.Computer.Registry.SetValue("HKEY_LOCAL_MACHINESOFTWAREMicrosoftJet4.0EnginesJet 4.0", "MaxLocksPerFile", "9000000")

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)
