A generic error occurred in GDI+.

Question

0.00/5 (No votes)

See more:

I loaded an image into a picturebox using:

picturebox1.Image = Image.FromFile()

And save it by using:

Bitmap bm = new Bitmat(pictureBox1.Image);<br />
bm.Save(FileName, ImageFormat.Bmp);

It works perfectly fine when creating a new file, but the moment you try to replace the existing image I get thrown a runtime error- A generic error occurred in GDI+.
So what can I do to solve this problem??

Image.FromFile() lock file.

"The file remains locked until the Image is disposed."

C#

FileStream fs = new FileStream(FileName, FileMode.Open, FileAccess.Read);
picturebox1.Image = Image.FromStream(fs);
fs.Close();

Bitmap bm = new Bitmap(picturebox1.Image);

bm.Save(FileName, ImageFormat.Bmp);

Solution 2

Check if the file already exists.
If so, delete it.
Then write the new file.

Can I do it by the code?

I think it wouldn't work also because of locking file while using Image.FromFile(). You'll get error on delete.

Solution 1

I don't see why your code shouldn't work. But try using passing a stream instead, might work who knows.

C#

Stream stream = new FileStream(FileName, FileMode.Create, FileAccess.Write, FileShare.None);
Bitmap bm = new Bitmat(pictureBox1.Image);
bm.Save(stream, ImageFormat.Bmp);
