Tech Note 13: PictureBox Control

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

NS Basic/Desktop

General

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:

• Display Bitmap (bmp and 2bp), Gif, Jpeg, and XBM image files.
• Display bitmap resources from resource files, including common bitmaps such as FileOpen and FileClose.
• Capture and display an image of the physical screen.
• Save an image as a bitmap file.
• Display and animate playing cards like the ones used in the Solitaire game provided with Windows CE.
• Clip, Invert colors, Mirror, Resize, Rotate, and Scroll an image.
• Display any image with a transparent color.
• Provide access to individual pixels in the image.
• Specify colors using RGB or QBColor notation.
• Overlay one image on top of another.
• Draw lines, rectangles, circles, polygons, and round rectangles.
• Change the color depth of an image.
• Refresh the Desktop Wallpaper.
• Support better drawing, See DrawMouseMoveLineEx.
• Support 64K color displays.
• Support Drawing Text.
• Support Command Button emulation.
• Support Label emulation.
• Use Scroll Bars.
• Display icon resources from executable files, resource files, and icon (*.ico) files.
• Support the PictureBox on the NS Basic Toolbar.
• Tap and hold support for the Pocket PC.

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.
