Saving picture to SQL (PictureBox) GDI Error
-
I have seen tons of people having this issue on google but haven't found a resolution yet. This is my code on getting the byte array from the picture. Then I try to insert it into a database. But it ALWAYS fails and gives me this: A generic error occurred in GDI+.
byte\[\] GetPicData() { MemoryStream ms = new MemoryStream(); pictureBoxPicture.Image.Save(ms, ImageFormat.Jpeg); byte\[\] invPic = ms.ToArray(); ms.Close(); return invPic; } -

Nope.. didn't work... I dug deeper into the breakpoints and see this: ReadTimeout '((System.IO.Stream)(ms)).ReadTimeout' threw an exception of type 'System.InvalidOperationException' int {System.InvalidOperationException} base {"Timeouts are not supported on this stream."} System.SystemException {System.InvalidOperationException} + WriteTimeout '((System.IO.Stream)(ms)).WriteTimeout' threw an exception of type 'System.InvalidOperationException' int {System.InvalidOperationException} + base {"Timeouts are not supported on this stream."} System.SystemException {System.InvalidOperationException}

byte\[\] GetPicData() { MemoryStream ms = new MemoryStream(); pictureBoxPicture.Image.Save(ms, ImageFormat.Jpeg); byte\[\] invPic = ms.ToArray(); ms.Close(); return invPic; }Hi, GDI+ has the tendency to name every problem happening in Image.Save() a "generic problem occured in GDI+". It could be a full disk, a locked file, whatever. In your case the MemoryStream can hardly fail (unless you are near an out-of-memory situation), but your image itself could be invalid (not sure how you would get PictureBox accept an invalid image, unless you first assign it to PictureBox.Image, and then do something to it. :)

Well I use a OpenFileDialog to select a file and set the pictureBox.Image. Then I use the above code when you click the Save button to get the bytes and insert it into a column in a database... but it never even gets to that. I tried this and it works (not very well for large images over VPN):
byte\[\] GetPicData() { MemoryStream ms = new MemoryStream(); Bitmap bmNew = new Bitmap(pictureBoxPicture.Width, pictureBoxPicture.Height, PixelFormat.Format24bppRgb); Graphics g = Graphics.FromImage(bmNew); g.DrawImage(pictureBoxPicture.Image, new Point(0, 0)); g.Dispose(); bmNew.Save(ms, ImageFormat.Png); byte\[\] invPic = ms.ToArray(); ms.Close(); return invPic; } -
Do you think there is another way of getting the image from the picture box and saving it to a sql database?
try this
new Bitmap(pictureBoxPicture.Image).Save(ms, ImageFormat.Png);

BTW: The PictureBox serves no purpose except it gives some size. If your image happens to be zero*zero pixels, it could still work, whereas maybe PictureBox.Image (and hence the original code) would not work, I don't know. I avoid PictureBoxes, they tend to cause more trouble than what they are worth. :)

Works the same but with less code and looks better. You know if I am saving it as a png file do I have to export it from the database as a png?

you mean no error now ?

yes...png is best format.

like ? I never got any problem with PB. I use BackgroundImage instead.

Hi, I paint my images myself, typically onto a Panel. That avoids problems such as: - I want my pictures to preserve aspect ratio while being rescaled - I want to select pixels with the mouse, even when the image has been rescaled - I want to be able to draw a rubber band, even when the image has been rescaled etc. All of these are either impossible or much harder than they deserve to be when using a PB. The one thing I would consider using it for is for displaying an animated image (multiTIFF and the like). :)

well, If you're a pro programmer then you should use the appropriate control. PB is for pictures and panel for containing other controls. Am I wrong...? All the operations you're doing with Panel can be done with PB but since Panel is more powerful in itself, its not good to compare with PB. Its like byte(PB) and int(Panel).

I agree with both of you. I am not a Pro Programmer (yet :-) lol), but I see the advantages of both. One, I know how to use a picturebox (well I thougth I did before this issue, but it seems to be a little bug), and I do not know how to paint pictures at ALL. I would like to learn it, and I think I might try the panel way to just test it out. Not really sure where to begin so I will google painting image on panel

Hi, there are lots of articles that demonstrate how to paint things. My Sokoban article is a simple example, the playing board actually is a Panel. :)
