Auto-generate Custom Number For Database In Asp.net Vb
Jan 27, 2012
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 am using vb to make a hospital system which works with a access database. i am having an issue with the updating function to the database, this time round instead of hard codding the connection i used the connection/data source wizard, in microsoft visual studio 2008 and there fore most of the code has been auto generated for me, which includes the insert, delete and update funtions from what i can find and what i have read vb is ment to also auto generate this which it is not. the funny thing is that i can close the program down and reload it (as long as i haven't opened the database) and my changes are still there but if i go and open the database and it hasn't changed. also i can change the database through the use of the Dataset connections in the datasource tab but not int he program the code ive found and believe that is meant to update the database
This is running off a couple of buttons i also have a update query but have know way of accessing it
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).

Anyway, I'm primarily a web developer so I'm only really fluent in PHP and everything else it entails.For my assignments the examination board suggests Visual Basic, so I'm just needing a little help as I'm not too great at it yet. [code] How could I ensure it generates a number 1-13 BUT doesn't ever generate a certain number, e.g. generate a number 1-13 but NOT 7.
Generating item codes for my inventory system became complex when the panel said that this must be the format of the generated ID number: "CATEGORY-ITEMNAME-ITEMINDEX" For example: School Supplies - Coupon Bond short- Second Item in the database would result to an item ID : SCS-CBS-002.

I build a component class it extends a combo box and generates some random numbers. But when I drag and drop my component from the toolbox to a form it auto generates Me.Randtest1.Items.AddRange(...) in the Designer which uses static numbers. The idea was to have different numbers each time and not the same.[code]
With VB.net, I'm coding a simple application to get more used to the new .Net format.
I'd like to save all the information to a 'new' database file. how to create a database on the fly, once that is done i'll be able to connect to it no problem, but actually creating the file is proving difficult to work/find out.
Also, with vb.net and the newly created custom file, how can it be made to automatically open that information with the program?
Is there a method in installation to associate the file type with the new program? How can i check when the program loads if a database file has been 'double-clicked' (rather than just running from the .exe of the program) and proceed to load the data?
EDIT1 - Extra InfoThe windows application has many different fields and content etc, then i need to save that to a file that could later be loaded by 'double clicking'. I assumed the easiest way would be to create a mini-database for each unique file
This is what I would like to achieve:To create a custom messagebox, with varying number of buttons with custom .Text descriptions, and other features. I intended to have a property array that would be redim-ed and have values (.Text values) set by the calling class:
I want to automatically generate VB.NET forms using tables from a SQL Server database (one form / database table). It is perhaps possible with writing custom custom code for it, but if there is already some feature that does the job that would be great (database has 40+ tables, manually doing this is a tedious task).
