I have a Table with an integer ID number set to auto-increase. Does anyone know how to let SQL server fill the gap (where rows are deleted) when new rows are added? If can, how to get the scalar ID number assigned?

I saw lots of things online that look like you can't create a number that increments with every build automatically - rather you have to set it in AssemblyInfo.vb - is that really the case??

But I just updated my workstation from XP Pro x86 to Vista Ultimate x64 and now it isn't working any more. Everything else works, but not this. It increments the build number when I build the application, but then VS gives the following error:Error 4 Unable to apply this change while debugging. File 'D:My ProjectAssemblyInfo.vb' was reloaded. You must revert the change or stop the debugging session.So essentially I can't do anything in my application, or at least I can't run in debug mode because of the error.

View 4 RepliesI have less than good eyesight now as my age increases :) I have managed to make most text areas/dialogs etc suitable for my eyesight, but can't find any way to edit/alter the Toolbar Icons - I expected to fin (at least) a seting for 'large' icons, or a way to increase/decrease the sizes - but so far I haven't been successful.
I find the icons/toolbars to be poorly designed in that they are on a grey background which just serves to minimise their effect.
May I ask a question to you all.I have vb.net project that generate sales report from SQL Server Database.I changed SQL Server 2005 Express to SQL Server 2005 Standard Edition.
After that my program can't run properly and every time I got Time Out Expire message.
That program work properly with SQL Server 2005 Express.May I request suggestion how to fix this.
I have an application I have developed which works great on individual PC's. However I've had some interest from a few customers that asked if I have a network version for site licencing.If my app did not save any data or write any reg entries, this might have been ok. But it does to the local computer. I also built in my own copy protection and trial function that stores data in the registry on the local computer.What would I need to do to enable my application to run on a server/network share, so that the only a serial number needed is for the server?
View 3 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")

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 -
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Str(4) As String

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:
