Syntax

Synchronous authentication Hide the details

<Result> = FBStartSession(<Session>)
<Result>: Boolean
  • True if the connection was established,
  • False otherwise.
<Session>: fbSession variable
Name of fbSession variable corresponding to the connection to initialize.

Asynchronous authentication Hide the details

FBStartSession(<Session> , <WLanguage procedure>)
<Session>: fbSession variable
Name of fbSession variable corresponding to the connection to initialize.
<WLanguage procedure>: Procedure name
Name of the WLanguage procedure ("callback") called during the connection. This procedure has the following format:
<Procedure name>(Connection, Session)
where:
  • <Connection> is set to:
    • True if the connection was established,
    • False otherwise.
  • <Session> is a variable of type fbSession that corresponds to the initialized connection.
Remarks

Starting the session

  • FBStartSession authenticates users on a Facebook server. This function initializes the connection with the server and it must be called before any communication with Facebook.
  • WINDEV A window allowing the user to type his login and password is automatically opened.
  • The FBStartSession function must only be called from the main the thread of the application.

Stopping the session

A started Facebook session is a persistent session: it will remain opened:
  • until the application is closed.
  • until the call to FBStopSession.

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 line of code 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)
Business / UI classification: Business Logic
Component: wd270ggl.dll
Minimum version required
