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?

A picture is displayed from a webcam into a picturebox. That picture must be saved to a specific folder.

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.

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.
I am creating a shell for a FORTRAN application which reads a tab delimited text file.Because I am using Excel to manipulate data, is it possible to use the Excel Automation features to "save as" a tab delimited text file?The only method available seems to be a unicode text format, which does not work. Or is there another format that mimics tab delimited so that the FORTRAN application will read such a file without difficulty?
View 1 RepliesI have an asp page with vb.net code that will query a database and present the user with the number of records that exist that need to be exported along with a button to export them. After you push the export button, it will prompt for a location and filename. But after that, it will not refresh the page with the new counts that now exist. Or in this case update the count to zero for the button they clicked.
[Code]
So how can I tell the page to refresh with the new counts. It almost seems like I need to tell the process to wait until after the user has finished finding the location and saving the file but I don't want to add a generic threading.thread.sleep in, I want it to only wait until they are done and then refresh the page.
