Hello,
I'm an absolute beginner at the Revit API and at this stage I am trying to do something very simple (no practical use, really, just experimenting with the API and how to return values to a winform):
- Create ribbon and buttons (works fine)
- Open a winform when clicking the button (works fine)
Problem area begins here:
- Trigger an external event when clicking a button on the winform
- After raising the event (_exEvent.Raise();) the winform closes itself (tried both this.Close(); and this.Dispose()) - this works fine, the form always closes. I close the winform so that Revit can pick up the external event and execute it.
- Have Revit execute this: MyGlobalVarible.myGlobalVariable = "Success!!!"; Here I use a public static string (see below why)
- At this point the External event reopens the winform and the winform displays MyGlobalVarible.myGlobalVariable (as the name suggests I make this variable accessible throughout the entire namespace so that I can pass values between classes freely).
All of the above works. However, it works inconsistently. Sometimes it does all it has to do 20 times in a row (winform closes, variable gets updated, winform reopens), and sometimes when I click the button on the form it just closes without reopening. Has someone else encountered the same behaviour? Maybe someone knows how to address this. Code snippets below.
Global variable declared in the plugin's namespace:
public class MyGlobalVarible
{
public static string myGlobalVariable;
}
Raising the external event by clicking a button on my winform:
public void button7_Click(object sender, EventArgs e)
{
ExternalEvent _exEvent = null;
EventRegisterHandler _exEventHandler = null;
_exEventHandler = new EventRegisterHandler();
_exEvent = ExternalEvent.Create(_exEventHandler);
_exEvent.Raise();
this.Close();
}
The external event implementation:
public class EventRegisterHandler : IExternalEventHandler
{
public void Execute(UIApplication app)
{
MyGlobalVarible.myGlobalVariable = "Success!!!";
var MainForm = new Form2();
MainForm.ShowDialog();
}
