Saving A Picture From A Picture Box?
Nov 6, 2009
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?

I'm creating an application that works like a recipe box. it has a picture box that is in the design of an index card, and it has 3 text boxes. I am having extreme difficulty saving the text boxes with the picture. i am using a database so that the info can be filtered, by recipe name, course description (appetizer, side dish...etc).

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.

save as
savefiledialog1.Title = "Save File"
savefiledialog1.FileName = "Capture"
savefiledialog1.Filter = "JPEG (*.jpg;*.jpeg;*.jpe;*.jfif)|*.jpg;*.jpeg;*.jpe;*.jfif|PNG (*.png)|*.png"

How could I do a quick save option so that it auto saves to a certain location that the user doesn't have to choose and as a .jpg?

I have VS 2008 and use VB, not C#/C++ or whatever else. I'm trying to make a battleship game, and I've decided to use the only method I can think of to control the grid. A 2D boolean array for position marking. I have the array set up, and the grid set up in the design form, but I can't figure out with all my research how to link them together. I'm writing this program to shake off the rust before school starts again, and for fun. I took VB in school last year, a half year class, so I have a foundation, now I'm self-educating myself above and beyond the class. I've searched for a way to use a picture box array to use the coordinates of the ship to .Visible=True the picture boxes. I've been working on this for 2 days straight with no results. I just need a little nudge in the right direction. The exception I've been getting with my latest concoction of code is NullReferenceException was Unhandled. I think its referring to the fact that I have no idea how to link the picture boxes into the array. Here's my code, and I'll comment where the exception is thrown:
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click

I get "a generic error occurred in GDI+" raised. Googling reveals a few hits for this problem but seemingly mostly related to using databases rather than the file system.
Has anyone come across this? I don't want to paste all my code here in case my nemesis is watching, however basically I'm getting a reference to the PictureBox's Image property and manipulating the pixels using GetPixel and SetPixel, and then setting the picturebox's image property = my modified bitmap.
I understand that the error is generally related to the bitmap not being ready to be saved - is there anything specific I need to do to "close" the bitmap so it can be saved?The strange thing is that I'm sure this was working earlier today and now seems to have arbitrarily stopped working.
