ShowDialog() while another form is visible through ShowDialog() as well, closes both?

I wish did fix the issue. Removed a couple of buttons, added a new one: solved.
So I think it should have been a DialogResult somehow, weird stuff.

What events are triggered when ShowDialog(ParentForm) is called in C#

this will help You can override the OnVisibleChanged method in your settings form. Make sure to call base.OnVisibleChanged though as to not screw up any potential observers of the event (and anything else the base class may do inside of that method.)

C#: inner workings: events, Control.BeginInvoke and program exiting = Interruption?

may help you . You'll have to delay closing the form if you want to ensure all BeginInvoked delegates are executed. You can do so by making it a two-step process, appending another BeginInvoke delegate to the queue that actually closes the form. Like this:
    private bool closing;

    protected override void OnFormClosing(FormClosingEventArgs e) {
        if (!closing) {
            closing = true;
            // Do your stuff
            //...
            this.BeginInvoke(new Action(() => this.Close()));
            e.Cancel = true;
        }
        base.OnFormClosing(e);
    }

How can I trigger jQuery events when entering or exiting fullscreen?

To fix the issue you can do I have a Fullscreen button on my page. I want to use it to make a target element fullscreen. I would like specific jQuery events (fullscreenOn/fullscreenOff) when fullscreen is entered and exited. I would also like the fullscreen button to be removed if the browser doesn't support fullscreen. , I wrote a jQuery function:
$.fn.fullscreen = function(target){
    var elem = $(target)[0]; $d = $(document);
    if(elem.requestFullscreen || elem.msRequestFullscreen || elem.mozRequestFullScreen || elem.webkitRequestFullscreen){
        function FSon(){ $d.trigger('fullscreen').trigger('fullscreenOn').data('fullscreen',true); }
        function FSoff(){ $d.trigger('fullscreen').trigger('fullscreenOff').data('fullscreen',false); }
        $d.data('fullscreen',false)
          .on('fullscreenchange',function(){
            if(document.fullscreen) FSon();
            else FSoff();
        }).on('mozfullscreenchange',function(){
            if(document.mozFullScreen) FSon();
            else FSoff();
        }).on('webkitfullscreenchange',function(){
            if(document.webkitIsFullScreen) FSon();
            else FSoff();
        }).on('MSFullscreenChange',function(){
            if(document.msFullscreenElement) FSon();
            else FSoff();
        });
        this.click(function(){
            if(elem.requestFullscreen){
                elem.requestFullscreen();
            }else if(elem.mozRequestFullScreen){
                elem.mozRequestFullScreen();
            }else if(elem.webkitRequestFullscreen){
                elem.webkitRequestFullscreen();
            }else if(elem.msRequestFullscreen){
                elem.msRequestFullscreen();
            }
        });
    }else{
        this.remove();
    }
};
$("#myButton").fullscreen("#elementToMakeFullscreen");
function n(){$d.trigger("fullscreen").trigger("fullscreenOn").data("fullscreen",true)}function r(){$d.trigger("fullscreen").trigger("fullscreenOff").data("fullscreen",false)}$d.data("fullscreen",false).on("fullscreenchange",function(){if(document.fullscreen)n();else r()}).on("mozfullscreenchange",function(){if(document.mozFullScreen)n();else r()}).on("webkitfullscreenchange",function(){if(document.webkitIsFullScreen)n();else r()}).on("MSFullscreenChange",function(){if(document.msFullscreenElement)n();else r()});this.click(function(){if(t.requestFullscreen){t.requestFullscreen()}else if(t.mozRequestFullScreen){t.mozRequestFullScreen()}else if(t.webkitRequestFullscreen){t.webkitRequestFullscreen()}else if(t.msRequestFullscreen){t.msRequestFullscreen()}})}else{this.remove()}}

Events raised from a ShowDialog Form aren't raised all the way to a calling vb6 app via com interop?


Tag : vb.net , By : WellBeing

will help you Modal dialogs have their own inner message pumps. Perhaps because that inner message pump is .NET controlled instead of VB6 controlled, there is an incompatibility? As in, the VB6 message loop is satisfying something VB6 needs that the .NET message pump is not doing?
In any case, personally I moved away from events in COM interop scenarios in favor of using an explicit callback interface. The advantage of this is there is no message pump involved at all, you bypass any issues related to that.
Private ox As ClassLibrary2.Class1

Private Sub Command1_Click()
  Set ox = New ClassLibrary2.Class1
  Call ox.MySub(Me)
End Sub

Private Sub IClass1EventListener_OnMyEvent(ByVal sParm As String)
  Debug.Print sParm
End Sub
Private Sub Command1_Click()
  Set ox = New ClassLibrary2.Class1
  Set ox.Listener = Me
  Call ox.MySub()
  Set ox.Listener = Nothing
End Sub
