    <p>I am using the TaskDialog within WindowsAPICodePack. When I try to create a TaskDialog without just a TaskDialogProgressBar and TaskDialogButton it throws the follow exception.</p> <p>System.ComponentModel.Win32Exception was unhandled Message=Invalid arguments to Win32 call. Source=Microsoft.WindowsAPICodePack ErrorCode=-2147467259 NativeErrorCode=0 InnerException: System.ArgumentException Message=Value does not fall within the expected range. InnerException: </p> <p>I wanted to have a TaskDialog with the ProgressBar to report the Status, but I dont want the user to close the dialog until the Progress is completed. So I am using a TaskDialogButton instead of the Standard Close button.</p> <p>Here is the code I am using.</p> <pre><code>_taskDialog = new TaskDialog(); _taskDialog.Cancelable = true; _taskDialog.Caption = "Delete Account"; _taskDialog.InstructionText = "Deleting Account(s)"; _taskDialog.Text = "Please wait until the delete operation completes."; TaskDialogProgressBar progressbar = new TaskDialogProgressBar(); progressbar.State = TaskDialogProgressBarState.Marquee; _taskDialog.ProgressBar = progressbar; TaskDialogButton btnClose = new TaskDialogButton(); btnClose.Click += new EventHandler(OnCloseClick); _taskDialog.Controls.Add(btnClose); //_taskDialog.StandardButtons = TaskDialogStandardButtons.Close; _taskDialog.Icon = TaskDialogStandardIcon.Information; _taskDialog.OwnerWindowHandle = this.Handle; _taskDialog.StartupLocation = TaskDialogStartupLocation.CenterOwner; _taskDialog.Show(); </code></pre> <p>EventHandler for Close Button Click</p> <pre><code>void OnCloseClick(object sender, EventArgs e) { if (_taskDialog != null) _taskDialog.Close(); } </code></pre> <p>-Matt.</p>
