Handling an Image control by programming
Overview
WINDEV, WEBDEV and WINDEV Mobile allow you to handle an Image control by programming. To do so, use the variable of the Image control in the code.
The variable of Image control corresponds to the name of Image control. This variable is a text variable.
Displaying an image file in an Image control
WEBDEV - Server code

In a page

To display an image file in an Image control, a simple assignment is sufficient.
If the image is available in the "<ProjectName>_WEB", directory, you have the ability to use the following syntaxes:
  • WEBDEV - Server code Server code:
    <Image control> = <Image name>

    Remark: In server code, if the image is available in a directory other than "<ProjectName>_WEB", you must:
    • specify the full path of image.
    • have read rights in this directory.
  • WEBDEV - Browser code Browser code:
    <Image control> = FolderWeb() + <Image name>

    Remark: if the option "Locate the image in the _WEB directory in browser code" is checked ("Details" tab in the control description window), FolderWeb is useless. The following syntax can be used:
    <Image control> = <Image name>
    Remark: If the control is associated with an item of a data file, the assignment is automatically performed via FileToPage. For more details, see Linking an Image control to an item.
Retrieving the name of the image file displayed in the Image control
WEBDEV - Server code

In a page

To retrieve the name of the image displayed in an Image control:
  • perform a simple assignment. For example:
    EDT_CurrentImageContent = IMG_Image1
  • use Value.
  • use Libellé (server code only).
WEBDEV - Server code In a server code, these syntaxes allow to obtain the name of the image defined in the "General" tab of Control. Example: ./background.gif
WEBDEV - Browser code In browser code, these syntaxes are used to retrieve the full image name on the server.
Example: http://localhost/addressbook_Web/background_fr.gif
Remark: To retrieve the image (or its name) in the item associated with the Image control,
  1. If the field is associated with a text Item, the value entered is automatically retrieved using the PageToFile function. You also have the ability to use the following notation: CUSTOMER.NAME = EDT_Edit1.
  2. If the control is associated with a binary memo, use HLinkMemo to associate the image file with the item.
    For more details, see Linking an Image control to an item.
Retrieving the position of the mouse in a clickable image
Clearing or reinitializing the content of an Image control
To clear or reinitialize an Image control, all you have to do is assign an empty string to the Image control. For example:
IMG_MyImage = ""

Remark: You also have the ability to use dStartDrawing/dEndDrawing on the Image control.
