I want to write the code not use the autonumber in Access as my lecturer does not want me to do it this way
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 want to update a row in an ACCESS DB in vb.net using sql query. the way to point to the row is using the primary key. the problem is that i was an error saying that there is a data type mismatch in criteria expression. the primary key type is auto-increment.[code]
View 1 RepliesI've been using some recommended code from successfully for a couple of years now to auto-increment the build number in my project.
[URL]
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.
It was very practical to keep build number in VB6, as it auto-incremented that number every time that i "compiled" the program.
There is any equivalent feature in VB.Net? I am using VS 2005.

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 constructed my database and I have used auto increment the ID's of each column. When I was testing and inserting data into my tables the auto increment of these column's of course incremented.
Now I am looking to start each individual Id column at 1 and not at the number where it is now.
I know it has something to do with using max value and +1. I have deleted the entire table and have tried everything to re-insert my data and start the ID's at 1, but I have had no luck.
Also to,
I know within Vb I can use a datagrid view and add there and it starts at the max value of the column +1, but when I have another form to add data within columns the column number is not in numerical order, How do include code within that seperate form to auto increment ID column numerically?
