Hi Experts,

I have a console app that tries to save an image from a local directory to a UNC Path (Shared Folder on a Network Drive).

I am able to do save it without any issues on another local folder, but not to the Shared drive.

I get the error "A generic error occurred in GDI+." of an ExternalException.

Your help would be appreciated

Are you running the application as a user who has permissions to the share?

@kaufmed:

I do not have an app.config for now. But yes I did try giving my credentials as

<system.web>
    <identity impersonate="true" userName="domain\myUserName" password="xxxxx"/>
  </system.web>

But my application is a console application. So, that wouldn't work.

destroy the bitmap after save then redeclare it

Bitmap bm = new Bitmap(mypath);
bm.Save("Shared Folder\\out.bmp" ,System.Drawing.Imaging.ImageFormat.Bmp );
bm .dispose();
bm = null;

or you can save a temporary file on local folder then copy it to the shared drive (safer solution)

@sognoct:

The error occurs exactly at the line where I call the Save method. I am also calling the Dispose() method as suggested by you and still get the error. Any other ideas?

just for debugging try to save to local folder...

string appPath = Path.GetDirectoryName(Application.ExecutablePath);
string tempbmp = appPath + "\\out.bmp"
bm.Save(tempbmp ,System.Drawing.Imaging.ImageFormat.Bmp );
bm .dispose();
bm = null;
io.file.copy(tempbmp, "\\\\sharedfolder\\" + filename; 
 

Open in new window


if it throws io error maybe is a permission issue ... if it is still GDI error, there is another possibility. In fact Bitmap cause GDI error if it is originated by a filestream and the filestream has been closed.
In this case must create a new bitmap objects that has not a closed filestream. So if bm is the original bitmap:

      //create temporary
      Image t=new Bitmap(bm.Width,bm.Height);
      //get graphics
      Graphics g=Graphics.FromImage(t);
      //copy original
      g.DrawImage(bm,0,0);
      //close original
      i.Dispose();
      //Can now save
      t.Save(path)

Open in new window
