I've designed my report and then when I click on the Preview tab, nothing appears and I get
System.Runtime.InteropServices.COMException (0x80004005): Command "View.Output" is not available. at EnvDTE._DTE.ExecuteCommand(String CommandName, String CommandArgs) at Microsoft.ReportDesigner.Utils.ShowOutputWindow(IServiceProvider sp) at Microsoft.ReportDesigner.Design.PreviewFrame.RefreshPreview() System.Runtime.InteropServices.COMException (0x80004005): Command "View.Output" is not available. at EnvDTE._DTE.ExecuteCommand(String CommandName, String CommandArgs) at Microsoft.ReportDesigner.Utils.ShowOutputWindow(IServiceProvider sp) at Microsoft.ReportDesigner.Design.PreviewFrame.RefreshPreview()
The funny thing is that it works now and again. It's frustrating because I have to continually deploy my report to test it.
