How to get file name of after DisplayFromFile("")

[RNeall]

If I use GdViewer.DisplayFromFile(""), how can my program learn the filename the user selected? There appears to be no property within GdViewer for file name.

Thanks,

Randy

Hi Randy,

Sorry for the delay. Currently there is no way to get file path used to open a document. I've added the feature on our whish-list.

Kind regards,

Don't worry. I used the generic file dialog instead.

Hi Loïc,

is it foreseeable when this feature will be available ?
So it would be very nice to get the filename after i use the DisplayFromFile-Method.

Kind Regards

Hi,

Unfortunately we have not implemented it yet, but here is what you can do:

Go to our demo c#/ImageProcessing, and in the Open Routine there is such an implementation, to make things easier:

Code: Select all

string file;
String Name;
int m_CurrentImage;
GdPictureImaging Imaging = new GdPictureImaging();
                DialogResult result = MainFormReference.openFileDialog1.ShowDialog(); // Show the dialog.
                if (result == DialogResult.OK) // Test result.
                {
                    file = MainFormReference.openFileDialog1.FileName;
                    try
                    {
                        m_CurrentImage = Imaging.CreateGdPictureImageFromFile(file);
                        if (m_CurrentImage == 0)
                        {
                        Name = Path.GetFileName(file);
                        }
                   }
                   catch (IOException)
                    {
                    }
               }
                

Hope this helps.

I figured out a better way to return the file path of the current image.

When displaying an image, save the file path to the .tag property of the image viewer:
GDImgCtrl.Tag = FileLocation

When you want to figure out what the current file path is use the code:
If GDImgCtrl.PageCount > 0 then currentfilename = GDImgCtrl.Tag

There is now an internal function for such purpose.
From the reference guide:

You can subsequently use the GetLastPath() function to retrieve the path of the selected file.
