Overview of the Web Camera control

Page control

The Web Camera control is used to view a file that is refreshed at regular time intervals. This file can correspond to an image broadcasted by a "web camera" for example.

Creating the control

To create a Web Camera control:
  1. On the "Creation" pane, in the "Usual controls" group, expand "Image" and click "Web Camera".
  2. Click the position where the control will be created in the page. The control appears in creation mode.
To display the control characteristics, select "Description" in the control popup menu.
Required configuration

Retrieving an image broadcasted by a "Web camera"

To retrieve an image broadcasted by a "Web camera" control:
  1. On the computer linked to the "web camera": configure the recording of the image broadcasted by a "web camera" (name of the file, rate of refresh, "web camera" used, ...). This setting can be performed:
    • by the software supplied with the "web camera".
    • by the "WD WebCam.exe" application available from the PC SOFT site (download page, "Other software" paragraph).
      The image file must be accessible from any computer that is using the WEBDEV site.
      Remark: The source code of "WD WebCam" is available in the examples provided with WINDEV.
  2. On the development computer: specify the image file linked to the Web Camera control ("General" tab in the control description window).
