) As Integer
'Usage
Dim instance As _Global
Dim App As String

string App,
string Topic
)
Parameters
- App
Type: System.String
Required String. The name of the application.
- Topic
Type: System.String
Required String. The name of a DDE topic— for example, the name of an open document— recognized by the application to which you're opening a channel.

Remarks
Dynamic data exchange (DDE) is an older technology that is not secure. If possible, use a more secure alternative to DDE.
If it's successful, the DDEInitiate method returns the number of the open channel. All subsequent DDE functions use this number to specify the channel.
