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 Dim newItm As ListViewItem[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 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.

How to autogenerate number in a texbox. in Visual Basic .NET 2005 and Using OLEDB I hv created 1 application in which there is one field in the database called "treatment ID"... and now i want to Autogenerate an ID in Incrementing Manner.
i do have a table with 3 cols, 2 of those will visible for users to enter data, the last one is needed to get inserted as the next number of the previous number.
i use the following query for insert command ,
INSERT INTO [Headers] (GrpId, GrpName, Number) Select (Select Case when Max(GrpId) = Null then 1 else Max(GrpId)+ 1 end from [Headers]),
make autonumber ID for my database. [URL] I followed the instruction there to solve the problem. I came up with this code.
Try Dim maxid As Integer strsql = "select StudID from tblStudent"
[code].....
I thought I already made it right because I was able to insert the first record with the right autonumber for ID which is 2012-00001 until I tried to insert the second record. It says that (Conversion from string "2012-00001" to type 'Integer' is not valid) and the highlighted part is (maxid = cmd.ExecuteScalar).
I am making a project in which if SID 001 is saved .after this SID textbox should display 002 automatically .I am using an Access Database. My code is as shown below:

I am using this code for row deleting in gridview. It should be like this "while it deleted a row, take row number 5 with serial no 5, serial field of row number 6 should become 5. means decrementing the serial number after one row deleted." but it is not happening while I delete row no 5 with serial 5, the row number 6 remains the same.
This feels like a completely basic question, but, for the life of me, I can't seem to work out an elegant solution.
Basically, I am doing a LINQ query creating a new object from the query. In the new object, I want to generate a auto-incremented number to allow me to keep a selection order for later use (named Iter in my example).
Here is my current solution that does what I need:
Dim query2 = From x As DictionaryEntry In MasterCalendarInstance _ Order By x.Key _ Select New With {.CalendarId = x.Key, .Iter = 0}
[Code]....
Is there a way to do this within the context of the LINQ query (so that I don't have to loop the collection after the query)?
i have a small database .mdf (sql server database) contains wallpaper table for ex. and a textbox for search. when someone write "wallpaper" in search box, i want to make my form adding Picturebox automatically On the basis of the number of images in the database, i mean i have 1000 image calls "blue wallpaper" in database, i want to see 1000 picturebox in my form and every pictruebox Displays a picture.
My code: it is used to generate number in date format my problem is that it doesn't show any output in the textbox nor in the database. The last num in my database is 2012010001.
Dim i As Integer Dim strSQL As String Dim strMonth As String Dim strYear As String Dim strTheID As String Dim today As Date [Code] .....
I would like to generate a tracking number as primary key for my database.
There will be total 12 letters for each tracking id. Example: 2012010001-1
The "2012010001-1" is actually from combination YYYYMMxxxx-v where YYYY is the current year, MM is the current month, xxxx is the auto generate number(increment) and -v is the version where it can be -2 -3 but using the same YYYYMMxxxx.
For both YYYYMM is not a prob as i can get the value from Date.Today.Month/Date.Today.Year. But how am I going to ensure the xxxx is an auto increment but will be reset back to 0000 every new month.
For example:
2012010000-1 (Month January, so start from 0000) 2012010001-1 2012010002-1
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??
Say I have a table called tblTest in MS Access with the primary key called field0 which is set to autonumber and a few other fields, say field1, field2 and field3. Say also, I inserted a new row using:
SqlO = "Insert into tblTest (field1, field2, field3) Values (value1, value2, value3)" Dim cmdO As OleDbCommand = New OleDbCommand(sqlO, conn) cmdO.ExecuteNonQuery()
I have a data set with a table named IEA_Transaction_Test2.After executing the below codes to insert a record into the SQL server table IEA_Transaction_Test2, how do I get the identity value (auto number) of the record that just got inserted?
