I recently downloaded VB2008 express. Iam trying to create a link to an SQL table, but the LINQ to SQL class is missing in my add new item menu. is there another way to grab data from a database without using the LINQ to SQL?
View 1 RepliesHow do I make a menu item on a menu strip link to another windows form (like a menu item that links to an about page already created in the project). I know that every coder knows how to do this, but i've read most of the instructions in the world for Visual Basic coding, but can't find ANYTHING I know coding fairly well, so I can modify it, but I can't create it my self.
View 4 RepliesI want to read a number of items from a file and then associate each of those items with a new button at run-time, so that when the user clicks one of the buttons I can display some information about that item.Can I use a LIST to manage these buttons and items? Can I create a new class and have each list item of that class, such as 'btnID', 'btnText', etc... ?
View 2 RepliesUsing VB 2010 Express, I will try to explain what I want to achieve:1. The user installs my program.2. In an Explorer window (Vista/Win7) the user will right click any file.3. The program checks if there is an item called "MyApp" in the context menu (i.e. the menu with for instance the "Open with..." item). If not, then create the "MyApp" item which launches "TheRealApp.exe" that the user installed. Place the item after the "Print" item.
View 1 RepliesI have an interface 'ICRUDable' and a class called ClientAddress which implements the ICRUDable interface.
My understanding of OOP would lead me to believe that if I declare a System.Data.Linq.Table(Of ICRUDable) then I should be able to put ClientAddress's in there.
The code I have tried includes;
Dim dc As New CRMDataContext
Dim items = dc.ClientAddresses

In my programming task I've gone down a dark alley and wished I hadn't, but there is no turning back now.
I'm building up a SQL statement where the table name, column name and id value are retrieved from query string parameters i.e. ("SELECT [{0}] FROM [{1}] WHERE [Id] = {2};", c, t, id)
But it isn't as bad as it looks, I'm protected: Only authenticated users (i.e. signed in users) can execute the Page_Load I'm checking that both the table and the column exists beforehand (using GetSchema etc.)I'm checking that the Id is an integer beforehand All my tables have Id columns The database connection is reasonably secure

I have a datagridview which is bound to a local databse table through a Linq to SQL class.
Everything works as I would expect, when the application runs, up to a point.
If, in the datagridview tasks pane I enable Adding, Editing and Deleting all work as expected.
If I disable Adding & Deleting, leaving Editing enabled, Editing works as expected.
If I disable Deleting & Editing, but leave Adding enabled, Adding does not work, despite the row for new records being displayed. I can move around the row but not enter data.
I suspect somehow its the datasource as opposed to the datagridview that is the cause of my problem but as I say, I can add rows if the Enable Editing option is selected.
Changing the relevant properties programatically makes no difference.
I've been searching for the reason for a couple of days without success.
I have a workaround, by leaving Enable Editing set and programatically setting each row during the RowPostPaint event to be readonly except the row for new records. I would just like to understand what is going on.

code for creating a class in vb.net for a database table that includes insert,delete,update function.
View 1 RepliesCreate a class to deal with records from the Classes table, much like the Student class we created in Lecture #17 handles Students records. The name of the class should be Ualb_Class (note we cannot use Class, as it is a reserved word in VBA). All of the fields should have corresponding properties. There are few considerations:
The class (course) code, department code, and course number are set at Initialize, so there is only a Get property method for those
The property for Meeting Day only accepts one of the values defined in the table. You can decide whether to accept an integer value or a string value of the days represented.
You are also to code the Initialize method, much like we coded the Initialize method for the Student class in Lecture #17. In the Initialize method, you will use the InputBox function to obtain the department code and course number. use a different InputBox for each value, so you don't have to mess with separating the single text value returned from that function. The Course Code will be obtained by using a function that has already been created, called GetNewCourseID. It has no parameters.

what is the fasted way to get all the rows from table1 that aren't in table2? i have over 4000 rows in table1, i am currently looping through using:
for each dr as datarow in dt1.rows
then i check table2 to see if that entry exists using:
dim rows() as datarow = dt2.select("EmployeID = " & dr!EmployeeID)
if rows.length > 0 then it exists in both tables - dont need it
other wise i copy the row into a third table which ends up being my final collection of rows that are in table1 and not in table2. this takes a really long time. is there a better, faster way that isn't too complicated?

View 1 RepliesIn XAML, ValueMemberBinding can be defined like the following:

But in coding, I found that there is no such valuememberbinding. For example:

I cannot find ValueMemerBinding in the AutoCompleteBox class.
