Application As Object, _
ConnectMode As ext_ConnectMode, _
AddInInst As Object, _
ByRef custom As Array _
)
'Usage
Dim instance As IDTExtensibility2
Dim Application As Object
Dim ConnectMode As ext_ConnectMode
Dim AddInInst As Object
Dim custom As Array
instance.OnConnection(Application, ConnectMode, _
AddInInst, custom)
void OnConnection(
Object Application,
ext_ConnectMode ConnectMode,
Object AddInInst,
ref Array custom
)
void OnConnection(
[InAttribute] Object^ Application,
[InAttribute] ext_ConnectMode ConnectMode,
[InAttribute] Object^ AddInInst,
[InAttribute] Array^% custom
)
function OnConnection(
Application : Object,
ConnectMode : ext_ConnectMode,
AddInInst : Object,
custom : Array
)
Parameters
Application
Type: System.ObjectA reference to an instance of the integrated development environment (IDE), DTE, which is the root object of the Visual Studio automation model.
ConnectMode
Type: Extensibility.ext_ConnectModeAn ext_ConnectMode enumeration value that indicates the way the add-in was loaded into Visual Studio.
AddInInst
Type: System.ObjectAn AddIn reference to the add-in's own instance. This is stored for later use, such as determining the parent collection for the add-in.
custom
Type: System.Array%An empty array that you can use to pass host-specific data for use in the add-in.
Remarks
OnConnection is the main method for IDTExtensibility2, because it is called every time an add-in is loaded. It is the entry point for an add-in when it is loaded, so you can put any code here (or call any another function) that you want to run when the add-in starts.
Examples
Public Sub OnConnection(ByVal application As Object, ByVal _
connectMode As ext_ConnectMode, ByVal addInInst As Object, _
ByRef custom As Array) Implements IDTExtensibility2.OnConnection
applicationObject = CType(application, DTE2)
addInInstance = CType(addInInst, AddIn)
MsgBox("Add-in is connected.")
End Sub
public void OnConnection(object application, ext_ConnectMode
connectMode, object addInInst, ref Array custom)
{
applicationObject = (DTE2)application;
addInInstance = (AddIn)addInInst;
System.Windows.Forms.MessageBox.Show("Add-in has connected.");
