Writing to the Output Window From a Visual Studio .NET Add-in |   | Can I write to the Output window from an add-in in Visual Studio .NET? Yes, you can and you can also create your own pane to write your output. Through automation, you can enumerate the existing output windows, add a new Output Window Pane, and write text to the existing panes or to your newly created panes. Place the following code blocks in the Macro IDE and execute them to see the results of their respective functionality. To use the code in an add-in, change all references to DTE to applicaltionObject.
The following code will list the Name Property of each existing Output Window Pane in the respective pane.
Public Sub WriteToOutputWindow()
Dim win As Window = _
DTE.Windows.Item(EnvDTE.Constants.vsWindowKindOutput)
Dim ow As OutputWindow = win.Object
Dim owPane As OutputWindowPane
For i As Integer = 1 To ow.OutputWindowPanes.Count
owPane = ow.OutputWindowPanes.Item(i)
owPane.Activate()
owPane.OutputString(ow.OutputWindowPanes.Item(i).Name)
Next
End Sub
|
The following code will add a new pane to the collection of panes in the Output Window and then write some text in the new pane.
Public Sub WriteToMyNewPane()
Dim win As Window = _
DTE.Windows.Item(EnvDTE.Constants.vsWindowKindOutput)
Dim ow As OutputWindow = win.Object
Dim owPane As OutputWindowPane
Dim cnt As Integer = ow.OutputWindowPanes.Count
owPane = ow.OutputWindowPanes.Add("My New Output Pane")
owPane.Activate()
owPane.OutputString("My text1" & vbCrLf)
owPane.OutputString("My text2" & vbCrLf)
owPane.OutputString("My text3" & vbCrLf)
End Sub
