Database Control Binding - Create A Record Add Information To It And Click On Next Record
Nov 15, 2009
I have a problem with my program, and it's really bad because I need to burn it to disk within 12 hours and I can't get it to work: If I create a record, add information to it and click on Next Record, the ID, Status and Notes boxes content will change but the rest of the controls contents are carried over to the next record and I don't know why or how. It was working perfectly but now it stopped and I never done anything.

I've got the following VERY basic code
[Code]....
this does indeed update my label with the first item in the Author field in my database, but I can't for the life of my figure out how to go the next record when I click a button. Could anyone give me a quick rundown, or a good tutorial on this, I'd rather not use the built in wizards.

I'm having trouble on how to code this. First I need to assign a value for every item in the list (1 for the first item, 2 for the 2nd and so on). Does this control have a separate field for the value aside from text?
Second, I need to insert this into my database(MSSQL 2008) in this format:
insert into table values(ID,selectedvaluegoeshere)

I want to create small database which handles Student Attendance Record it will store the roll calls of students on daily basis that teachers collect from the students in the class on paper and then later transfer it on computer .So my database Must contain Month, Year, Program (BCS, BIT, MS, MCS, MIT etc) Batch (1st, 2nd etc) and Subject (English, Math, Geography etc)
Suppose I want to Search for the Attendance Sheet of any month, year, Program, Batch or Subject, it returns me the required dataSo i come up with the Datadase which includes 5 dimension tables and one fact tableDimension Tables1. Student (StudentID, Name, other Attributes)2. Program (Program_Name, other Attributes)3. Date (Date, Week, Month, Year)4. Batch (Batch_Number, Description)5. Subject (Subject_Name, other Attributes)Fact TableAttendanceTable ( StudentID, Program, Date, Batch, Subject, Status)but the problem come when certain columns are repeating again and again which is time consuming for database operator and shows inconsistent behaviour of database.
Look at it: my Fact table would be like this [code]....
problems:1. The StudentId is repeating which shouldn't (Primary Key),2.It wastes a lot of time coz i'm repeating the data again and again Like Program, Date and Batch which shouldn't be in consistent Databases.

I'm working on a VB Winform project using Visual Studio 2008. The form's controls are all bound to a bindng source and a binding navigator which are tied to a dataset class. When the form is displayed, the first record is displayed as well. However, one of the controls (Radio button) is not showing the correct data from the data set. However, if I navigate to the next record and move back to the first, the radio button properly displays the correct information, so it appears the binding source is working the way it is suppose to.

Using Binding Navigators to tables in datasets. How are you all managing putting default values into new records? How are you handling "general" row validation before allowing them to save the record? We actually save on the current change event of the BN right now - client does not want to use a save button. But still how would you "stop" the current change from happening if the record was not yet valid enough (like filling a couple of foreign key fields)?

Why would this code - that loads lots of VENDORS into this dataset - only show "1 of (1)" on the binding navigator?
VendorBS is the BINDING SOURCE.
Private Sub vendorLoad()
Dim connectString As String = "Server=fps-lap-szsqlexpress; Initial Catalog=Casefiles; Integrated Security=SSPI"

When I am on my modify page and you scroll through the records with the Binding Navigator, somehow the previous records data stays on the screen and puts it into the next data. Now this only happens on my one screen with 2 combo boxes. How do I get my information to stay put so that users don't have to worry about scrolling through multiple records and screwing up the data?

i am fairly new to VB.Net programming having been a VB6 developer for years (the copmany i used to work form maintained VB6 apps)?I am writing a new application. I have created my form, databindings to the fields and everything works ok.
In order to filter through the dataset i have decided to use BindingContexManager. I have tried currency manager also.The problem i am incurring is that when i click button next it goes forward 3 records then loops back to the first record again. If i skip to the end of the dataset i can browse back 26 records before it loops back ot the first record and gets stuck in a loop.

there is a tab control system. It relies on only five text boxes, and their bindings change when the tab is changed The relevant information is displayed. However, if I navigate to a different record...You can see that the same information is displayed in the tab control text boxes, and not the employee's details I just selected in the data grid or the navigation. How can I fix this? I'm not sure what's gone wrong here. Here's the code that changes the text boxes upon changing tab...
Private Sub TabCheck()
If TabState = 1 Then
pnlTabs.BackgroundImage = My.Resources.tabs1

While I've previously many years of relational databases and procedural languages, I'm stumbling with Visual Basic. In this problem, the simple situation is that I have two files, parent and child. The primary key of the parent file (Area file) is linked by a relation to one of the two fields that makes up the primary key in the child file (Project file) (unique key is formed from 'area' and 'project'). I have the default table adapters created on both files. I have created two maintenance forms showing one each of the two files in datagrid view format.I can create some records in the Parent (Area) file, but when I try to create a record in the child (Project) file, using one of the valid key values from the Area file, I get the 'ForeignKeyConstraint [relation name] requires the child key values [actual value] to exist in the parent table' which I'm absolutely definitely sure it does.
I haven't done any actual coding for those two maintenance forms, just dragged-and-dropped the files from the data sources screen onto separate forms so it creates the controls itself. But I can't work out, if it already knows the data does exist because I can load it back in to the Area maintence form, why it can't check itself to find out the record does exist. Why does it think the record from the parent record doesn't exist? It does exactly the same thing, whether or not the database is in access or SQL Server Express. I have all the latest updates.

I have two tables Products and Categories with a many to many relationship. I am trying to copy the categories linked to one product (OriginalProduct) to another product (newProduct). The problem is when I execute the SaveChanges() method, I not only get the records in my linking table, but it also creates another copy of the categories in the categories table. I've tried this in many ways but here are the last couple that I've attempted:
' Copy Product/Categories
For Each oneProdCategory In OriginalProduct.Categories
Dim relatedCategory = _productContext.GetObjectByKey(New EntityKey ("ProductInfoEntities.Categories", "RecordId", oneProdCategory.RecordId))

The one area I am have a problem is PositionItem. I would like to sense that the User has changed the Record Number in the BindingNavigatorPositionItem, handle my record Update, and move to the Record Number the User entered I have looked all over and have not found any way to do this.

I have created a project that has an add a new record, edit record and a search form, that has multiple text, combo boxes and is working great.Last nite I have added a checkbox under my add new record form and i am saving the checkbox value to my database, so far so good. I would like to be able to search any record that is mark with a checkbox to show up in my search screen when I do a search: [code] The problem that i am having is that now that I have added the code to my project to search for the checkbox field in the search screen and if I leave everything blank and click on the the search button I get no record found. I expected to see all that data, since I have nothing selected. Now if I click my checkbox, as soon as I click on my search button I see that two records that I have added for my test.

I have a collection of objects (classes I created), and each one ties to a record in a database. I want an easy way to update the information, so I thought about declaring a record in the class, that would tie to the record on the database. However, I'm having a problem updating it now.
1) Can I declare a global variable for the data context, and leave it open the entire time the program is running? This would solve my problem, but I don't know if I can do that.
2) If not, besides coming up with a complicated class to do this, is there an easier way? Here is an example of what I am trying to do:
VB.NET
Public C as Record
Public Sub GetValue()
Dim SQL As New DBDataContext
Dim X = From T in SQL.Records Select T
