I am new to vb.net. I created a vb.net script to autogenerate a code. Now, after generating this code, what I want is to determine the validity of this code. for example, a code has been generated now and this code will be valid for 24 hours only.
Below is my script for the auto generation code
Dim randomvalue As New Random
Dim randomhold As Integer
Dim newcode As Long
For i As Integer = 0 To 9999
randomhold = randomvalue.Next(1, 9999)
newcode = randomhold & DateTime.Now.Minute & DateTime.Now.Year
Label3.Text = newcode
Next
The code generated will be sent via sms. If the code hasn't used within 24 hours, it will be invalid.
i'm worried about doing this since my changes will be overwritten when the dbml file is auto generated again (as they often are).i'm thinking of doing a partial class and writing out the same properties to annotate them, but worried that it will complain about duplicates, and the reason i can't even experiment brings me to the second part of my questions...
that, the expandable arrow on my dbml file listing is missing, right clicking and selecting "View Code" just displays an empty partial class as below.

View 2 RepliesI have a database I am creating with about 50 users over a network. There are about 6 groups of users and these users are spread across 10 branches. I want to block/allow users from particular forms and views. For example I want branch users forms to be filtered by their branch number but depending on the group they are in they can only see some forms. i.e. 50 users, 10 branches, each branch has about 5 ppl of where 1 is in group A and 4 are in group B. I want all users that belong to branch 1 to see the information they enter, but Group B enter data but cannot approved or delete, and group A can enter, approve and delete. So then. On my login form I have the user type his/her username but the i want LEAVE function to update 2 textbox where I have named GroupName and BranchNo. Basically to run a query and look for the username and return in one textbox that user's groupname and the other textbox the user's branch no. This information will be used to filter forms and block the user from certain controls. This is the code I have so far but still can't figure how to display the results.

According to the General Naming Conventions the usage of CLR type names (e.g. String, Int16) should be preferred over the usage of language specific type names (string, short). I usually follow this advice. Resharper however seems to use the language specific type names when generating code (eg. when extracting methods or generating foreach loops) which is very annoying.
