i need to upload and display images to and from database. i have written this code for uploading and it uploads fine. except 1 problem. It crashes when i dont select an image. can someone help me fix it for null value? also how do you display an image in IE?
code for inserting image -
Dim imageInfo As FileInfo = Nothing
Dim data() As Byte = Nothing
imageInfo = New FileInfo(Me.UploadLogo.Value.Trim())
Dim imagestream As FileStream = New FileStream(imageInfo.ToString, FileMode.Open)

I am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields:
QuestionNumber (unique integer key)
QuestionText
QuestionType
In my SQL Server database I created a Table called "QUESTION" with the same fields.
QuestionNumber is defined as integer unique key, auto increment
Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1).
How do i have to change my database setup, that the original QuestionNumbers are copied into the database?

I'm not sure what to use to insert a file that's located on the server into the sql database. I've read a bunch of articles but none of them show how to just grab a file without using fileupload.

I am trying to insert a new row of data into table in an Access2010 database.There are 5 fields in the table called Users. ID, Username, Password, Manager_Access and Admin_Access. These fields contain data types ID(autonumber this is the primary key), Username(text string),Password(text string) and Manager_Access and Admin_Access are true/false boolean. I am using a comboBox, a textBox and two checkBoxes as the source of the new row data.I have used the Dataset Designer to raise an INSERT Query on the Users table called InsertNewUserRecord. The SQL statements look like this.
INSERT INTO Users[code]....
I have set the ExecuteMode in the query properties to Scalar.The code then looks like this
Dim Username As String = ComboBoxUsername.Text
Dim PW As String = TextBoxPassword.Text()
Dim MR As Boolean = CheckBox1.Checked[code].....
I am getting error messages telling me "Syntax error in INSERT INTO statement.If I try a query with just the Username and Password which are both text then it works fine.If I try a query with just one of the Boolean fields it works fine.If I try both Boolean fields or the text fields and one Boolean field then I get errors.

I want to track changes in an application. So I've made a copy of the main table in that application, and am accessing both tables in the application using two separate datasets.
My plan was to use the HasChanges method of the main DataSet to get changed rows and then insert those into the copy table. When I run the code I get an error:
A first chance exception of type 'System.InvalidCastException' occurred in MyApp.exe
Unable to cast object of type 'MainDataTable' to type 'MainAuditDataTable'.
Here's the code:
If Me.DataSet3.HasChanges Then
' 'look for each row that has changes, not new rows
' 'insert that row into the auditing table

I'm quite new into the programming game, I've been working on this program for a few weeks now, and its coming along, but the method I searched for entering new rows of data into my table doesn't seem to update my tables after I try entering data. I have a feeling it may be something very simple that i am over looking.
Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)

I'm having issues with the way I've been reading my image datatype blobs from my SQL database (code below). This code works fine when I access this page directly. The PDF will open and works just fine. However, when I try to use this page to download a file and save it to the file-system programmatically, it fails (500 server error) and I've verified that it's the same URL either way.So, my question is what is the best way to download a file from a database image datatype and save it to disk?PDF.aspx
