Solution2.IsOpen Property
Gets a value which indicates whether a solution is open.
Namespace: EnvDTE80
Assembly: EnvDTE80 (in EnvDTE80.dll)
Syntax
'Declaration
ReadOnly Property IsOpen As Boolean
bool IsOpen { get; }
property bool IsOpen {
bool get ();
}
abstract IsOpen : bool with get
function get IsOpen () : boolean
Property Value
Type: Boolean
true if a solution is open; otherwise, false.
Remarks
An open solution does not necessarily have a solution (.sln) file, because it might not have been saved yet.
Examples
For information on how to run this add-in code, see How to: Compile and Run the Automation Object Model Code Examples.
The following example displays the IsOpen state of the solution.
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)
IsOpenExample(_applicationObject)
End Sub
Sub IsOpenExample(ByVal dte As DTE2)
' This add-in displays the IsOpen status of the solution.
' Open a solution in
' Visual Studio before running this example.
Try
Dim soln As Solution2 = CType _
(_applicationObject.Solution, Solution2)
Dim solnName As String = _
System.IO.Path.GetFileNameWithoutExtension(soln.FullName)
MsgBox("Solution " & solnName & _
" has the following IsOpen state:" & _
vbCrLf & vbCrLf & soln.IsOpen.ToString())
Catch ex As System.Exception
MsgBox(ex.ToString)
End Try
End Sub
//you will need to add this reference to your project as well
using System.Windows.Forms;
public void OnConnection(object application,
Extensibility.ext_ConnectMode connectMode, object addInInst,
ref System.Array custom)
{
_applicationObject = (DTE2)application;
_addInInstance = (AddIn)addInInst;
// Pass the applicationObject member variable to the code example.
IsOpenExample((DTE2)_applicationObject);
}
public void IsOpenExample(DTE2 dte)
{
// This add-in determines if a solution is open.
// Open a solution in
// Visual Studio before running this example.
try
{
Solution2 soln = (Solution2)_applicationObject.Solution;
string solnName =
System.IO.Path.GetFileNameWithoutExtension(soln.FullName);
MessageBox.Show("Solution " + solnName + " IsOpen status is: "
+ soln.IsOpen.ToString());
}
catch(SystemException ex)
{
MessageBox.Show("ERROR: " + ex);
}
