This code shows me the preview of a webcam in a picture box. I want to know how to save a frame as a picture file.The code I'm currently using to save it (in the timer tick event) gives me the "Object reference not set to an instance of an object." error..Then I used a debug assert line and it gave me an error that basically says that there is no image in the picture box, while I can clearly see a picture in the picture box. Can anyone please help me write/edit the code to save it?

We are developing applications using VB .NET as front end and SQL Server as back end. We want to store and retrieve pictures in a database. We do not want to store the pictures directly into the database but rather the path of the pcitures so that through the same paths we can retrieve them.

I have some pictureboxes on this form set up to allow me to browse for images, then select one and show it in the box. How can I save the picture I pick so it updates a database and will show that picture when I cycle through the data in the program? It would be an SQL database and it already has columns for the picture. I don't know if I should store the path to the image or the image itself.

I've made a code which updates my database using a dataset and data binding source. I can retrieve all fields in the database including the �Picture� field which is set to �OLE Object� however I cannot update this. The Picture field in the dataset is set to type System,.Byte. I�ve search these forums and found how to do it manually which I can do and works but when it comes to the BindingSource.EndEdit section it still tries to update my �Picture� field and fails due to a type failure.
It was �System.InvalidCastException: Failed to convert parameter value from a Byte[] to a String. --->� What can I do to correct this? Below is my code. Note the image saves under the hard coding but not in the second part of the code.
Dim connection As New OleDb.OleDbConnection(My.Settings.AirportsConnectionString)
Dim command As New OleDb.OleDbCommand("UPDATE Airports SET Picture = @Picture WHERE ID = " & TextBox10.Text, connection)
'Create an Image object.
