Summary
Display data in VT220 emulation window.
Description
The WriteData property is used to display data in the VT220 terminal emulation window. Data is displayed by assigning a string to this property. Normally, an application will display incoming
data from the server in the emulation window by assigning the string containing the incoming data to this property. The ActiveX control takes care of all emulation required to correctly display the
data.
If an application handles the connection itself, then it must pass incoming data to the ActiveX control in this manner. If the ActiveX control is used to handle the connection, then an application
may still add messages to the VT220 emulation window by assigning them to this property. This allows the application to display progress information, such as "Trying..." or "Connected", in the VT220
emulation window.
This property can be set at run time after the VT220 emulation window has been initialized by calling the Initialize method ( or setting the Action property to ACTION_INITIALIZE.) There is no default
value for this property.
Note
The WriteData property can be used to insert any sequence of data including control sequences to change an option. For example to set the reverse video option you could set this property as
follows:
Vt220Client.WriteData = Chr(27) + "[m" + Chr(27) + "[7m"
Example
Sub VT220Client_OnConnect ()
Vt220Client.WriteData = "Connected."
Connected = True
End Sub
