Hi everyone. I'm trying to make an add-in which uses a windows form. For that, I copied the code used in the "Getting Started" walkthrough in the Revit API guide, and modifided it. I'm always getting the same error message: "SetCompatibleTextRenderingDefault must be called before the first IWin32Window object is created in the application.". Here is the code that I've tried to use.
CsAddPanel.cs:
using System;using System.Reflection;
using Autodesk.Revit.DB;
using Autodesk.Revit.UI;
using System.Windows.Media.Imaging;
using System.Windows.Forms;
namespace Walkthrough
{
/// <remarks>
/// This application's main class. The class must be Public.
/// </remarks>
public class CsAddPanel : IExternalApplication
{
// Both OnStartup and OnShutdown must be implemented as public method
public Result OnStartup(UIControlledApplication application)
{
// Add a new ribbon panel
RibbonPanel ribbonPanel = application.CreateRibbonPanel("NewRibbonPanel");
// Create a push button to trigger a command add it to the ribbon panel.
string thisAssemblyPath = Assembly.GetExecutingAssembly().Location;
PushButtonData buttonData = new PushButtonData("cmdHelloWorld",
"Hello World", thisAssemblyPath, "Walkthrough.HelloWorld");
PushButton pushButton = ribbonPanel.AddItem(buttonData) as PushButton;
// Optionally, other properties may be assigned to the button
// a) tool-tip
pushButton.ToolTip = "Say hello to the entire world.";
// b) large bitmap
Uri uriImage = new Uri(@"C:\globe.png");
BitmapImage largeImage = new BitmapImage(uriImage);
pushButton.LargeImage = largeImage;
return Result.Succeeded;
}
public Result OnShutdown(UIControlledApplication application)
{
// nothing to clean up in this simple case
return Result.Succeeded;
}
}
/// <remarks>
/// The "HelloWorld" external command. The class must be Public.
/// </remarks>
[Autodesk.Revit.Attributes.Transaction(Autodesk.Revit.Attributes.TransactionMode.Manual)]
public class HelloWorld : IExternalCommand
{
// The main Execute method (inherited from IExternalCommand) must be public
public Autodesk.Revit.UI.Result Execute(ExternalCommandData revit,
ref string message, ElementSet elements)
{
Form1 form1 = new Form1();
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
form1.ShowDialog();
//TaskDialog.Show("Revit", "Hello World");
return Autodesk.Revit.UI.Result.Succeeded;
}
}
}Here's a screenshot of the form that I'm trying to use (and of the SharpDevelop views):
Finally, here's a screenshot of the error message in revit:
Thank you
