VS 2010 Save Picture In Sql-database Or On Hard Disk?
Jan 31, 2011
I have a program for collecting data of people. Now i also have a picture of these people... what is the best thing to do? what is the fastest? the safest?
1. Converting a picture to a bytearray an then insert it into a sql -table (with al ready 5 columns).
2. making an new table on the sql database with just two columns (id-ref, picture-column)
3. or saving a file on to the hard drive? (if nescessary saving the url into the database?)

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?

Dim UserSelection As New System.Collections.Specialized.NameValueCollection

I need to save this instance to hard disk and then load it back from hard disk as an instance. How do I do that?

How would I find the letter for the hard disk? e.g C:
Because I know some computers have different letters insetad of C.
Also, on a slightly different topic (I didnt think it was worth starting a new thread for it), I need a program to start during the start up of the computer it is on, am I right in saying I need to create a shortcut (which I think is a .lnk file?) and then put that in the startup folder. I'm doing this in code, but I was wondering what information I need in the shortcut file.

I have a program that must copy a file to 3 locations, the local hard disk, a USB drive, and a network location. I have the file (about 70mb) loaded into a byte array. My quesion is, since I'm not actively modifying the byte array, can I impliment a form of multithreading where all 3 threads read the same byte array at the same time?

how to write a null bytes onto unused hard disk spaces? I understand that files deleted are still existed on hard disk, I am thinking of may be if I write the null bytes to every single unused bytes so that the unused hard disk space would be become all null bytes, and unused space would no longer contain of those deleted files.
