Tech Note 13: PictureBox Control

April 08, 2009

© NSB Corporation. All rights reserved.

Overview

The NS Basic PictureBox control (NSCEPictureBox.ocx) is available for NS Basic/Desktop and NS Basic/CE version 6 or later. It replaces the Microsoft PictureBox control (MSCEPicture.dll) and the S309 PictureBox (S309PictureBox.ocx). All functions in the older controls should work the same way in this control.

NS Basic/CE

AddObject "PictureBox" uses this control. As a result, older programs will automatically start using the control. However, if you used the long form of the name, "PictureBox.PictureBox", it will always use the Microsoft PictureBox control (MSCEPicture.dll). If you want to be sure you get this control, use AddObject "NSCEPictureBox.NSCEPictureBoxCtrl.1",...

NS Basic/Desktop

AddObject "PictureBox" uses a lightweight version of this control which is built into your program, much like the other intrinsic controls. To use the full control described in this Tech Note, use AddObject "NSCEPictureBox.NSCEPictureBoxCtrl.1",... or add it to the Toolbox in the IDE using the ActiveX Control Manager.

General

If your program uses this control, you will also need to redistribute NSCEPictureBox.ocx and register it on the target machine.

The PictureBox is also used as a container for forms. As a result, the functions in PictureBox are directly available for use on any form. Here is a list of features in NS Basic's PictureBox:

The PictureBox maintains the picture being displayed as an image, which is not necessarily the same width and/or height as the PictureBox. You can have the PictureBox automatically size itself to the width and height of the image or have the image stretched or shrunk to the size of the PictureBox when displayed. All drawing and pixel manipulation is done on the image.

Tips

  1. If your image does not load, try setting the property.ImageLoadBufferSize = 4096
  2. Use .DrawMouseMoveLine or .DrawMouseMoveLineEx methods in the _MouseDown, _MouseMove and _MouseUp events to draw smother lines with the
  3. The LostFocusX and GotFocusX events need to be used to track the focus of the control.
