I am an Architect relatively new to C#, I am trying to implement Ehsan Iran-Nejad's amazing PyRevit coloured tabs in my own toolbar.
https://github.com/eirannejad/pyRevit/blob/12ecea9096bb649e2b6f084ba82ba1284bc78667/extensions/pyRevitTools.extension/pyRevit.tab/Toggles.panel/toggles1.stack/Tab%20Coloring.smartbutton/script.py

Unfortunately for me, this is returning null:
public static Xceed.Wpf.AvalonDock.DockingManager GetDockingManager(UIApplication uiapp)
{
var wndRoot = (MainWindow)UIAppEventUtils.GetWindowRoot(uiapp);
if (wndRoot != null)
{
return MainWindow.FindFirstChild<Xceed.Wpf.AvalonDock.DockingManager>(wndRoot);
}
return null;
}
Launched from the external command:
[Autodesk.Revit.Attributes.Transaction(Autodesk.Revit.Attributes.TransactionMode.Manual)]
public class StartGroupingTabsExt : IExternalCommand
{
public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
{
if(DocumentTabEventUtils.IsUpdatingDocumentTabs)
{
DocumentTabEventUtils.StopGroupingDocumentTabs();
}
else
{
DocumentTabEventUtils.StartGroupingDocumentTabs(commandData.Application);
}
return Result.Succeeded;
}
}
I cannot see quite what is going wrong, any advice would be greatly appreciated.
Cheers,
Mark
I've had something similar happening when I was building something like that. I had referenced the xceed.wpf.avalondock library from nuget and that was what caused it. Maybe you did the same thing? If I instead referenced the dll that's in the Revit installation folder, it worked without a problem.

My C# app has lots of forms to perform various tasks. To keep things simple, I have a static class FormsCollection where the instances of each of the other forms are kept, so that they are shown and hidden from one place.
Now i was getting that classic debug time "Cross-thread" error. I tried to fix it the following way:
public class FormsCollection : Control // inherited from Control only to be
// able to call "this.Invoke"
{
public delegate void ShowFormDelegate(Form form);
public static Main mainForm;
// and many other forms...
public void ShowForm(Form form)
{
if (form.InvokeRequired)
{
ShowFormDelegate delegateFunc = new ShowFormDelegate(ShowForm);
this.Invoke(delegateFunc, new object[] { form });
}
else
{
previousForm = currentForm;
currentForm.Hide();
currentForm = form;
currentForm.Show();
}
}
}
Inside the user/caller forms, i simply make an object of FormsCollection and call the ShowForm method (almost a 100 such calls):
FormsCollection f = new FormsCollection();
f.ShowForm(FormsCollection.mainForm);
And after all this ordeal, what i get is that the same error appears at the very same spot as before! What an irony! :)
What am i doing wrong? Please help me out....
I got extremely hard-to-find answer to this problem from this slightly irrelevant page. Following is the updated code for any struggling programmers looking for a work around to this problem:
public void Show(Form nextForm)
{
Thread thread = new Thread(
new ThreadStart(() =>
{
PreviousForm.BeginInvoke(
new Action(() =>
{
PreviousForm = CurrentForm;
CurrentForm = nextForm;
PreviousForm.Hide();
CurrentForm.Show();
}
));
}
));
thread.Start();
}
This seems to have resolved the cross-thread problem that i was facing despite several work-arounds. It is working as yet without raising any exceptions and I have tested almost all the scenarios of my app going back and forth from form to form.
I need to pass an object with some information to consume in my Background Task. I try to search in web but not found any solution. It is possible?
One workarround is save information what I need to pass in isolated storage in my MainProjet and in my BackgroundTask project consume information saved before. But this solution is not beautiful to use.
Someone help me?
Thanks in advance
You can use SendMessageToBackground method
var message = new ValueSet();
message.Add("key",value);
BackgroundMediaPlayer.SendMessageToBackground(message);
In background task listen to this method
public void Run(IBackgroundTaskInstance taskInstance)
{
BackgroundMediaPlayer.MessageReceivedFromForeground += BackgroundMediaPlayer_MessageReceivedFromForeground;
}
private void BackgroundMediaPlayer_MessageReceivedFromForeground(object sender, MediaPlayerDataReceivedEventArgs e)
{
foreach (string key in e.Data.Keys)
{
switch (key.ToLower())
{
}
}
}
I have the following:-
[TestFixture]
class TaskServiceTest
{
public void Implements_ITaskService()
{
var service = CreateService();
Assert.That(service, Is.InstanceOf<ITaskService>());
}
private static ITaskService CreateService()
{
return null;
}
}
When I run that in Visual Studio / Resharper It is reported as 'Inconclusive'. The explanation of which in the NUnit Docs is
The Assert.Inconclusive method indicates that the test could not be completed with the data available. It should be used in situations where another run with different data might run to completion, with either a success or failure outcome.
I don't see that holding here, so can anyone explain what I am doing wrong?
Thanks
I just realised that it is because I missed the [Test] attribute off of the unit test.
[Test]
public void Implements_ITaskService()
{
var service = CreateService();
Assert.That(service, Is.InstanceOf<ITaskService>());
}
I'm new to Mvvmcross framework and currently exploring the iOS part of it (ohh and also new to iOS development to draw a beautiful picture of my current situation ^^). I'm using the vNext version.
I've found references to implementation of UICollectionViewController (MvxTouchCollectionViewController and MvxBindableCollectionViewSource), but these classes seem to be only a skeleton for a future implementation (abstract class, missing a kind of MvxSimpleBindableCollectionViewSource at least). I haven't found a sample using this feature.
I've also found a blog post from Stuart which lets presume he's working on this part (Work In Progress - MvvmCross lists sample).
Does anybody already play with this part and know about an implementation or usage example?
I've took a look to the 10 first minutes of the xaminar mentioned by Stuart in its article and seems pretty interesting, a good starting point for me.
I've used the collection view controller in several customer apps, but don't think I've published any open source samples that use it.
In essence, the use of the collectionview is very similar to the use of the tableview and cell - which is shown in detail in: http://slodge.blogspot.co.uk/2013/01/uitableviewcell-using-xib-editor.html
In vNext, a sample controller might look like:
public class MyCollectionView : BaseCollectionView<MyCollectionViewModel>
{
private bool _needToCallViewDidLoadManually;
public HubView (MvxShowViewModelRequest request)
: base(request, new UICollectionViewFlowLayout (){
ItemSize= new System.Drawing.SizeF (100, 100),
MinimumInteritemSpacing = 20.0f,
SectionInset = new UIEdgeInsets (10,50,20,50),
ScrollDirection = UICollectionViewScrollDirection.Vertical,
})
{
if (_needToCallViewDidLoadManually) {
ViewDidLoad();
}
}
public override void ViewDidLoad ()
{
if (ShowRequest == null) {
_needToCallViewDidLoadManually = true;
return;
}
base.ViewDidLoad ();
_needToCallViewDidLoadManually = false;
var source = new CollectionViewSource(CollectionView);
this.AddBindings(
new Dictionary<object, string>()
{
{ source, "ItemsSource TheItems" }
});
CollectionView.Source = source;
CollectionView.ReloadData();
}
public class CollectionViewSource : MvxBindableCollectionViewSource
{
public CollectionViewSource (UICollectionView collectionView)
: base(collectionView, MyViewCell.Identifier)
{
collectionView.RegisterNibForCell(UINib.FromName(MyViewCell.Identifier, NSBundle.MainBundle), MyViewCell.Identifier);
}
}
}
If you are starting development now, then you might also benefit from considering the v3 branch which is just entering Beta.
Wonder if somebody can help me with this. I am trying to open an embedded browser in an Eclipse RAP applications. All examples I have seen look something like:
link.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(SelectionEvent event) {
try {
Browser b = new Browser(parent, SWT.NONE);
b.setText("<html><body>This is Unicode HTML content from memory</body></html>");
} catch (SWTError e) {
// Error handling here
}
}
});
That doesn't do anything (visually) though. When I replace the Browser with ExternalBrowser like so:
link.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(SelectionEvent event) {
try {
int browserStyle = ExternalBrowser.LOCATION_BAR;
ExternalBrowser.open( "myPage", "http://www.stackoverflow.com", browserStyle );
} catch (SWTError e) {
// Error handling here
}
}
});
It works. Although not exactly as desired.
I am using Eclipse RCP 1.4.2 on OS X 10.8.2.
Any insight is highly appreciated.
When you create a new widget, you have to trigger a re-layout to make it visible. Depending on your layout, it may be sufficient to call parent.layout(). If the parent is also contained in a layout and shrunken to its preferred size, you will have to call layout() on its parent. If unsure, layout the top-level shell.
