I am having trouble with the insert command, my code is:
Protected Sub btnTestator_Click(sender As Object, e As System.EventArgs) Handles btnTestator.Click
Dim WillsDataSource As SqlDataSource = New SqlDataSource()
WillsDataSource.ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionString").ToString()
[code]....
aatblWills1 is my sql server table with 3 fields: WillID(PrimaryKey, integer auto increment); UserName(nvarchar(150)) and TestatorName(nvarchar(150)) (there are some other fields in the table but I've set them to allow nulls)I am not getting an error message, it is just not inserting any records into the database.
User need to select their prefferable data to show in report. What i did is i have a clear command first to delete the temporary table. The temporary table is basically a table to stored user selection parameter data. After the clear command, i have a insert command to insert user selection data into the temporary table. What happened now is when i run the program exe, first run of the report is work fined, but not the second and the following times of execution. It will return null or blank report. The weird thing is when i execute it from development environment, it seem like the report is able to pick up user selection parameter and run the report for the first times and the subsequent execution.
could someone tell me what i am doing wrong in this codeProtected Sub insert_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Insert.Click

Im trying to convert the nServiceBus PubSub .net4 example into vb and I'm struggling at one point which I think is a language issue but I thought I would ask the experts. The code in question is from the publisher:
In my code I can easily use "where Obj.Feld = String", but using "where Obj.Feld.StartsWith("a")" doesn't work. See the following two functions:

The first function (byFileName) works fine. The second function (LikeFileName) doesn't. Using Startswith I get "Object reference not set to an instance of an object." What am I doing wrong?Database is an array of Objects, a structure consisting of strings
A rectangle is painted in Sub pBox1_paint. My intent is to add data to pBox1 via 'drawstring' in Sub btnMoreThan30. The first line of Sub btnMoreThan30 originally included 'ByVal e As System.EventArgs'. The compiler flagged the phrase 'e.graphics' with the error:'Graphics' is not a member of 'System.EventArgs'. I then modified line 1 of this sub as it appears in the code below. The compiler finds no errors but when I click on button 'btnMoreThan30' I get the runtime error,'InvalidCastException was unhandled. 'Unable to cast object of type 'System.Windows.Forms.MouseEventArgs' to type 'System.Windows.Forms.PaintEventArgs'. How can I draw lines and strings in a picturebox from a button_click sub? Code follows:

I'm working on creating a windows service that will send emails to a customer when they are within a month of having their submission expire. I'm using vb.net in Visual Studios 2008
Because it's a windows service it's very difficult to debug. Trying to narrow down my error I created a "sendDebugEmail" method that sends me an email if it gets to a certain line. The emails never make it past "dr = cmd.ExecuteReader()"
I'm wondering what I am doing wrong. My SQL statement should work fine. I've tested it in my SQL server database.
I've created a dummy_database that I just made in sql server as well. I added an INSERT sql statement for the dummy table i have in there just to see if i could actually access a database. All the table takes in is the line number and time it was sent. When I run my windows service that database updates just fine.[code]...

I am fairly new to visual basic 2008 but not to visual basic(vb6). I want to insert a new row in the database table (library.mdb). I connected the database into my project and is bounded by a dataGridview control. I have no problem in getting the records from the database. I used the code under click event of a commandButton, after clicking the button neither the record inserts in the database table nor the program generates any error. The code I used is :
Dim bkrow As LibraryDataSet.Book_MasterRow bkrow = LibraryDataSet.Book_Master.NewBook_MasterRow With bkrow .B_no = B_noTextBox.Text .ISBN = ISBNTextBox.Text [Code] .....
Here Book_Master is the database table. LibraryDataSet is the dataset, Book_MasterTableAdapter (not used in the above code) is the TableAdapter. Is there anything missing in the above code? Is there any other method to enter data into the database in visual basic 2008?

I am having a problem with adding a record to a customer table in a Microsoft Access database. I have worked for hours reading my textbook and troubleshooting to no avail. The copy and paste below from VS is a little messy. When I execute this code below the record is not added and I do not get an error of any type. When I go into debug mode, all of the parameters are correct and everything looks good. If I open up Access I can manually add the record but using my program nothing happens. All datatypes are string in VS and text in Access.
First an instance of the Customer Class is created and this seems to be successful. But when I take that customer object and run the AddCustomer method of the customer class it is not successful in that the database does not reflect that the record was ever added. [Code]
Here is hte code I'm using to insert into my database:[code]I believe it is Cell 4 that is causing the exception, because it is a checkbox column and i'm not sure what syntax to use to store the "CheckedState" of it.Yes, I know I should be using parameters, but I don't know how yet, and I would like to make the INSERT statement work before implementing the paramater approach with it.
If I need to set the value of a checkbox (threestate) inside of an INSERT command, what would the syntax be? I've tried 'True' but that fails and I can't think of another way to do it.
