Use in a page

The HTML control of a page is used to display or use an HTML code or a JavaScript code. This code can correspond to HTML scripts for example. The HTML control cannot be used to display an HTML page or an HTML site. This control can only be used to display an HTML code.
An HTML control can be programmed in server code only if the control is defined as being a "Dynamic" control. The HTML control cannot be associated with an item of a data file.
Caution:
  • When the control is defined as being a dynamic control, it can only be assigned by programming.
  • The option "Allow the execution of scripts" is not enabled by default for the control ("General" tab of control description).
If the window displayed in the HTML control contains scripts and if the user clicks active areas in this HTML control (forms, tab, ...), the requested action triggers the opening of the default browser and displays the URL of HTML control in order to allow the user to run these scripts.
To allow the user to navigate inside the HTML control, check "Allow the execution of scripts".

Window control: Characteristics

Options of "General" tab

The "General" tab found in the description window of control is used to:
  • type HTML code or the address of HTML page to display.
    Note: If HTML code is typed, this code must necessarily be found between the <HTML> and </HTML> tags.
  • WINDEVAndroidiPhone/iPad allow the execution of scripts. This option is used to allow the execution of scripts called from the HTML code of control.
    iPhone/iPad This option is ignored: the execution of scripts is always allowed.
    Versions 23 and later
    If this option is checked, you also have the ability to:
    • run Javascript code in the context of Web page displayed by the HTML control. To do so, use ExecuteJS.
    • allow the execution of WLanguage procedures from the Javascript code via the option "Allow the WLanguage call from the HTML code (JavaScript WL.Execute function)".
      If this option is selected, in the HTML code of control, all you have to do is use WL.Execute to run a WLanguage procedure. The following syntax must be used:
      WL.Execute(<Name of WLanguage Procedure>, <Parameter>)
      where:
      • <Name of WLanguage Procedure> corresponds to the name of procedure to run.
        CAUTION: The WLanguage procedure must necessarily expect a single parameter.
      • <Parameter> corresponds to a character string that will be passed to the procedure. This parameter is mandatory.
      Example:
      • WLanguage procedure
        PROCEDURE ProcFromJS(t)

Caution: To use an HTML control:
  • WINDEV in a WINDEV application, Internet Explorer version 4 or later (version 11 recommended) must be installed on the development computer and on the deployment computer. The HTML control of WINDEV is in Internet Explorer 7 mode.
    To display WEBDEV pages in this control, the WEBDEV pages must be generated in HTML + Edge mode.
  • AndroidiPhone/iPadUniversal Windows 10 App in an application in simulator mode, Internet Explorer 4 or later (version 11 recommended) must be installed on the development computer.
  • Versions 21 and later
    iPhone/iPad in an iOS 9.0 application (and later), you must respect the security options. By default, the HTML control can only access the sites that use an HTTPS connection complying with the Apple recommendations. To access other sites (HTTP for example), you must either provide the list of corresponding domains, or disable the security for all the domains. These operations are performed in the wizard for creating an iOS application. See Generating an iOS application for more details.

Incompatibility between the IE ActiveX (and oAuth2) and the use of .NET assembly

When an HTML control is used in WINDEV, this control is using the system "Microsoft Web browser" ActiveX. This ActiveX is also used by WINDEV for all the OAuth2 authentications (Facebook, Twitter, Google, etc) that require a validation for the connection via HTML code.
If an HTML control (or an OAuth2 authentication) and a ".Net"assembly are used in the same project, an incompatibility may occur between the .NET layers of Microsoft and the ActiveX.
An API can be used to manage this cohabitation. To do so, the following code line must be used in the initialization code of the project or in the initialization code of classes or global procedure if the ".Net" object is initialized in the class or in the set of procedures:
// Used to manage the cohabitation between IE ActiveX and .NET
API("OLE32", "CoInitializeEx", Null, 2)

Page control: Characteristics

Page control: variable width and height

By default, the dimensions of HTML control are defined in the editor. If the HTML content of control is bigger, the content is truncated.
To modify this operating mode, check "Variable width" and "Variable height" ("Details" tab of the description window). In this case, the dimensions of the HTML control will adapt to the content of the control and the controls located beside or below the HTML control it will be moved accordingly.

Description window and programming

In the description window of control, you have the ability to type a text in the "General" tab of control. This text will be automatically converted to HTML.
The HTML control is used to display:
  • the content of a local HTML file.
  • the HTML content of an item.
To initialize the HTML control by programming, it can be assigned with:
  • an HTML code directly. For example:
    HTM_Code = "Hello"
  • the path of a local HTML file.
    HTM_Code = fExeDir() + "\MyHTMLFile.htm"
Notes:
  • The images in PNG and SVG format found in the HTML are not supported.
  • If the CSS style sheet corresponds to an external file, it is ignored.
  • All the external files that must be found on Internet are ignored.
  • The Javascript codes are not run.
