cover.Image.Save(path.Text & "mymovies-front.jpg", System.Drawing.Imaging.ImageFormat.Jpeg)
When i use the code above and chack the picture after save it shows me the "x" picture just before the picture is loaded i have had a look at picture.waitonload
this is so simple its embarrassing to ask. How do you display a picture in a picturebox? I want to have a static picture displayed on my single form application. I tried adding a picturebox control to the form and setting the InitialImage setting to my pgn file. But when the app loads they image is not displayed. I've googled around and found many references to adding pictures out of databases and etc, but nothing as simple as my. I just want to display the one image.

View 2 RepliesThis 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.

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.
View 14 RepliesI 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.
View 1 RepliesI'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)
