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.
  • WINDEV allow the execution of scripts. This option is used to allow the execution of scripts called from the HTML code of control.

    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)
        ToastDisplay("Called from JS: " + t)
      • Code of HTML control:
        s is string = [

Use conditions

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.
  • Universal Windows 10 App in an application in simulator mode, Internet Explorer 4 or later (version 11 recommended) must be installed on the development computer.
WINDEV

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 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)

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.

Control HTML = Control View PDF
Did you know that the HTML control allows you to view various types of files like JPG, PNG, GIF, PDF and many other types? Well, it is possible to visualize different types of files, just inform the HTML control to open the file via programming code containing the PATH of the file.

==== CONTROL HTML OPEN PDF ====

Você sabia que o controle HTML permite visualizar diversos tipos de arquivos como JPG, PNG, GIF, PDF e muitos outros tipos? Pois bem, é possível SIM visualizar diferentes tipos de arquivos, basta informar para o controle HTML para abrir o arquivo via código de programação contendo o PATH do arquivo.
