The following code example uses the derived classes VScrollBar and HScrollBar and sets their Visible property values, based on the size of an Image being displayed in a PictureBox control. This example requires that a PictureBox has been created on a form and that HScrollBar and VScrollBar controls have been created on the PictureBox. This code should be called when the image is loaded into the picture box and by the Resize event of the form.
Public Sub DisplayScrollBars()
' Display or hide the scroll bars based upon
' whether the image is larger than the PictureBox.
If pictureBox1.Width > pictureBox1.Image.Width Then
hScrollBar1.Visible = False
Else
hScrollBar1.Visible = True
End If
If pictureBox1.Height > pictureBox1.Image.Height Then
vScrollBar1.Visible = False
Else
vScrollBar1.Visible = True
End If
End Sub 'DisplayScrollBars
public void DisplayScrollBars()
{
// Display or hide the scroll bars based upon
// whether the image is larger than the PictureBox.
if (pictureBox1.Width > pictureBox1.Image.Width)
{
hScrollBar1.Visible = false;
}
else
{
hScrollBar1.Visible = true;
}
if (pictureBox1.Height > pictureBox1.Image.Height)
{
vScrollBar1.Visible = false;
}
else
{
vScrollBar1.Visible = true;
}
}
public:
void DisplayScrollBars()
{
// Display or hide the scroll bars based upon
// whether the image is larger than the PictureBox.
if ( pictureBox1->Width > pictureBox1->Image->Width )
{
hScrollBar1->Visible = false;
}
else
{
hScrollBar1->Visible = true;
}
if ( pictureBox1->Height > pictureBox1->Image->Height )
{
vScrollBar1->Visible = false;
}
else
{
vScrollBar1->Visible = true;
}
}
