ShowFileDialog Example VC++

Example 1 Open

This example shows how to use the ImgAdmin Open dialog box to display a file in the Image Edit and the Thumbnail controls.

void CAdmin1Dlg::OnFileopen() 
{
    // Initialize Image property in order to check for Cancel
    // pressed.  After the dialog box is shown, check for a value
    // in the image property.
    ImgAdmin1.SetImage ("" );
    // Specify a dialog title and a list filter rather than using
    // the defaults.
    ImgAdmin1.SetDialogTitle ("Select Image for Display");
    ImgAdmin1.SetFilter ("All Image Files |*.bmp; *.jpg; *.tif|
        Bitmap Files (*.bmp)|*. bmp|JPG Files (*.jpg)|*.jpg|
        TIFF Files (*.tif)|*.tif|All Files (*.*)|*.*|");
    // Default filter will be TIFF (fourth item).
    ImgAdmin1.SetFilterIndex (4);
    // Set the InitDir property to the preferred directory.
    ImgAdmin1.SetInitDir ("C:\\images");
    ImgAdmin1.SetCancelError (FALSE);
   // Note:  if you have Server Access software installed this
   // will automatically be enabled in the Open dialog box after
   // the user authenticates.
    VARIANT vhWnd; V_VT(&vhWnd) =  VT_I4;
    V_I4(&vhWnd) = (long)m_hWnd;
    ImgAdmin1.ShowFileDialog (0,vhWnd);       // OpenDlg
    // Determine if a file was selected or cancel was pressed
    if (ImgAdmin1.GetImage() =="")
            return;
    // Set the image properties in the ImgEdit and Thumbnail control
    // to the name of the file selected in the dialog box.
    ImgEdit1.SetImage (ImgAdmin1.GetImage());
    ImgThumbnail1.SetImage (ImgAdmin1.GetImage());
    // Display the image in the ImgEdit and Thumbnail control.
    ImgEdit1.Display();
}

Example 2 SaveAs

This example saves the displayed image with a new filename using the Admin Save dialog and the Image Edit control SaveAs method.

void CAdmin1Dlg::OnSaveas() 
{
    VARIANT vhWnd; V_VT(&vhWnd) =  VT_I4;
    V_I4(&vhWnd) = (long)m_hWnd;
    ImgAdmin1.ShowFileDialog (1,vhWnd);   // OpenDlg
    VARIANT evt;
    evt.vt = VT_ERROR;     // set to error for optional parameter 
    ImgEdit1.SaveAs (ImgAdmin1.GetImage(), evt, evt, evt, evt, evt);
}
