This patch adds exception type to be passed from JScripts callback
function. This allows one to selectively process exceptions without needing
to parse strings for words.

The patch also defaults the name of a networklink's node the name provided
in the KML (like in GE) rather than the type name if the link cannot be
resolved.

The existing PluginReady event handler sends the GE COM object as the sender. 

Normally one would wait for a PluginReady event to run the LoadKml on "this". 

However, if you are instantiate a GeWebBroswer class and set it's
PluginReady event handler to load some KML then this is impossible unless
you are local in the class.

public void showInGoogleEarth()
{
    ...

    GEWebBrowser browser = new GEWebBrowser()
    ...
    browser.PluginReady += new
GEWebBrowserEventHandeler(GEDisplayViewBrowser_PluginReady);

}

private void GEDisplayViewBrowser_PluginReady(object sender, GEEventArgs e)
{

    // sender here is of type IGEPlugin. unfortunately, this can't use the
GeWebBrowser 
    // helper methods..
    // so a better approach is to send "this" to this handler, then you can
do this: -
    GEWebBrowser browser = (GEWebBrowser)sender;
    browser.FetchKml("http://some/path/to/kml");
}

The attached patch doesn't change the existing handler but creates a new
one called PluginReady2 that can be used in the above way.

What should this feature enhancement do?
I'm just trying to figure out how to get the Lat/Long from a mouse click event 
on the globe.

Are there any known workarounds that produce the similar results?


Please provide any additional information below.
A while back I played with your lib and I recall it was a matter of calling the 
KMLMouseEvent, but that seems to be gone in the latest version.

What steps will reproduce the problem?
1. Try loading a file from the local machine rather than from a URL

What is the expected output? What do you see instead?
Local KML file should load, it doesn't.

What version of the product are you using? On what operating system?
Latest source, Vista

Please provide any additional information below.
I know this may not really be a bug, but for any practical use, a WinForms 
control really needs access to local files. Do you have a way of allowing 
the webBrowser control to access local KML files? Great control otherwise 
though - good work  :-)

*) Correct spelling of Handler
*) Replaced LoadKmlCallback with more generic InvokeCallBack allowing
JScript to decide which .Net callback to call.
*) Add Tag property to GEEventArgs  
*) Changed OnKmlLoaded signature to use new GEEventArgs Tag property to aid
call of InvokeCallback.
*) Added some COM Helper methids found from MSDN blog.
*) Added OnKmlFetched along with Thread Handle locking and KmlObject Cache.
*) Added FetchKmlSynchronous that returns a IKmlObject without adding to
GEWebBrowser instance. This helps resolve NetworkLinks.
*) Added additional parameter to LookAt so it can access GEWebBrowser
instance to call new FetchKmlSynchronous.
*) Allow LookAt to look inside NetworkLinks for AbstractViews.
*) Refactored LookAt.
*) Removed throw from GEStatusStrip when getStreamingPercent occasionally
throws COM exception.
*) Removed requirement in FetchKml that disallows paths ending in kml/kmz.
This inhibits using CGI scripts as kml sources.
*) Added ParseKml method that will render Kml string.
*) Updated JScript to use new createCallback function.


All these will help further development resolving network links.

What steps will reproduce the problem?
1. open attached project.
2. copy test.kmz file to local or other http server
3. adjust project to reflect new kmz url
4. run project in debug mode

What is the expected output? What do you see instead?

A windows form should appear showing the relevant kmz file in the geplugin
window. What happens is the geplugin crashes approximately 50% of the time
on several PCs tested. The bug appears to be a race condition in geplugin
introduced by the new javascript event handling code from svn revision 162.
You may need to re-run the project 10 times to get a feel on how often the
crash occurs.

What version of the product are you using? On what operating system?

Revision 162 and greater. Windows Xp 32 bit / latest service packs.

Please provide any additional information below.

Attached is a screen shot of a typical crash.

Attached is a patch that will allow the KmlTreeView to accept: -

                <ListStyle>
                    <listItemType>checkHideChildren</listItemType>
                </ListStyle>

What is the expected output? What do you see instead?
The Latitude and Longitude I'm getting are not exact. I want exact values 
because a polygon needs to be drawn on using that fetched latLong values.

What version of the product are you using? On what operating system?
Version - 5.0.11337.1968 (beta)

Double-clicking on a KmlTreeView node causes the node to be unchecked.

What is the expected output? What do you see instead?

In Google Earth, double-clicking a treeview node does not uncheck it.

What version of the product are you using? On what operating system?

r420 on XP.

Please provide any additional information below.

I did not observe this problem in the previous .NET 3.5/VS2008 version of the 
library.

In KmlTreeView.OnNodeMouseDoubleClick(), I was able to correct the problem by 
changing the following line at the top of the method:

Was:
  bool state = !node.Checked;
Now:
  bool state = node.Checked;

I'm new here and am attempting to recompile the project and am getting a 
type not found error on ImageryBase.

Great control-set by the way. Just what I was looking for.

I wanted to line up my tool strip items on the right.  I implemented a 
property (toolStipItemsAligment) in GEToolStrip.cs to enable this feature.  I 
wanted to share this work as I think it is a nice feature and has a somewhat 
unique solution.  Attached are my local copies of GEToolStrip.cs and 
GEToolStrip.Designer.cs

To reproduce:
start = 43.60336, -110.7362
dest = 43.59431, -110.8273
Expected result = 262.22
Actual result = 277.84

The first two lines of the function BearingInitial() are as follows:
double lat1 = ConvertDegreesToRadians(destination.Latitude);
double lat2 = ConvertDegreesToRadians(start.Latitude);

I believe they should be:
double lat1 = ConvertDegreesToRadians(start.Latitude);
double lat2 = ConvertDegreesToRadians(destination.Latitude);

FC.GEPluginCtrls 1.5.0.0, date 2010-07-05 21:44

Windows 7 Ultimate + Service Pack 1
64-bit Operating System

Please provide any additional information below.

The TestApplication that is available for download works fine. I have stipped 
its functionality to the bare minimum and the GEWebBrowser still works.
The application I have written for myself exists to maintain data for ancient 
archaeological sites. For refernce I want to embed the GEWebBrowser.
The network link for inclusion in Google Earth is

Is this possible? How?

What steps will reproduce the problem?
1.download latest version of test application (nr.5)
2.go to "bin" folder for compiled program
3.start the exe

What is the expected output? What do you see instead?
all the controls are frozen and earth does not appear

What version of the product are you using? On what operating system?
I guess the latest, on XP home Sp3 32 bit

Please provide any additional information below.
I tried also to compile with C# express 2010 with target FW .NET 4 but nothing 
changes. I also tested the base example code, the application starts but 
everything is frozen.

The GEWebBrowser PluginReady event doesn't seem to fire for me on Windows7.
Using the latest GEPluginCtrls and lasted TTGEPlugin, the event ever fires 
after calling LoadEmbededPlugin()..

What steps will reproduce the problem?
1.Attach a listener for any on of the viewchange events
2.Run the app
3.Change the view
4.the event is not being raised

What is the expected output? What do you see instead?
Expect the event to be raised once the event has been attached

What version of the product are you using? On what operating system?
Vista 64

Please provide any additional information below.
For some reason the view change events are not being raised in my c# 
code. I hook them up as follows; 

this.InvokeJavascript("jsAddEventListener",new object[] { (_ge.getView 
(), "viewchangeend"}); 

My listener is as follows; 

private void geWebBrowser1_KmlEvent(object sender, GEEventArgs e) 
{ 
bla bla bla 
} 

I am able to receive mouse events just not the viewchange events. I 
know this is a new feature but I have checked and seem to have up to 
date versions of everything. 

What should this feature enhancement do?

Regarding the event:

void kmlTreeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)

In the previous .NET 3.5 version, e.Node.Name would be "KmlPlacemark", 
"KmlPolygon", etc.  Now e.Node.Name is a unique key, and it looks like the type 
information is private (KmlTreeViewNode.ApiType).  Along the same lines this no 
longer works because Tag is now null:

kmlTreeNodeKPCCC = (KmlPlacemarkCoClassClass)e.Node.Tag;
kmlTreeNodeGeometry = kmlTreeNodeKPCCC.getGeometry();
kmlTreeNodeGeometryType = kmlTreeNodeGeometry.getType();

Are there any known workarounds that produce the similar results?

Maybe I just don't know the correct way to do this in the latest .NET 4.0 
version of the plugin...

Please provide any additional information below.

Hi, 
How can Distinction between 'placemark click and 'linestring click' be achieved.

i've added placemarks and linestrings to the plugin - together with 
eventlistners like so:
pm1 = GEHelpers.CreatePlacemark(.....);
this.geWebBrowser1.AddEventListener(pm1, EventId.Click);

var lineString = GEHelpers.CreateLineString(.....);
this.geWebBrowser1.AddEventListener(lineString, EventId.Click);

in the kml event I would like to do different things depending on what 
kmlobject has been clicked on:

void geWebBrowser1_KmlEvent(object sender, GEEventArgs e)
        {
            e.ApiObject.preventDefault();
            dynamic kmlObject = e.ApiObject.getTarget();
            string type = kmlObject.getType();

            if (type == ApiType.KmlPlacemark)
            {
            }
            if (type == ApiType.KmlLineString) 
            {
            }

However, the type is always kmlplacemark.

Should i check on id's instead ? 
string id = kmlObject.getId(); (if so the id should be added in the 
createlinestring() ?)

Regards,
Thomas

What steps will reproduce the problem?
1. Attempt to use Refresh after FetchKmlLocal.

What is the expected output? What do you see instead?
The kml file to refresh. An exception

NB:

Comment by joshua2519, Dec 01 (Dear fraser: I found a bug with 
FetchKmlLocal?(). when I fetch a local kml file, Refresh button will not 
reload the kml file. beacaue the kml File has been read by a thread.

I fixed this bug by adding a argument, FileShare?.Read in FetchKmlLocal?() 
show below FileStream? stream = File.Open(path, FileMode?.Open, FileAccess?
.Read, FileShare?.Read);

This patch really just fixes an edge case of an earlier path.

It checks that the obj.getOwnerDocument() call does not return null. It
also reverses the logic in that if it is null it will default to parsing
the kml container rather than nothing.

What steps will reproduce the problem?
1. Compile the FC.GEPluginCtrls
2. Embed it my application
3. Run outside of VS 2010

What is the expected output? What do you see instead?

What steps will reproduce the problem?
1. Check a root node
2. Notice child nodes don't auto check

What is the expected output? What do you see instead?
1. When checking a root object, I would think all sub nodes should also be 
checked / unchecked. If not, a user may have to check 10s or even 100s of 
boxes to get it all showing again.

What version of the product are you using? On what operating system?
Latest, Vista / XP

Please provide any additional information below.
Hey again!  :-D
I am having a problem with my application - users will be very frustrated 
if they have to click 10s / 100s boxes to get all placemarks back. I have 
tried checking them programmatically, but I keep getting a stack overflow 
exception due to CheckAllParentNodes() method. I tried this below, but 
obviously it doesn't help, because the features don't get turned on / 
off  :-)

this.AfterCheck -= new TreeViewEventHandler(KmlTree_AfterCheck);
foreach (TreeNode node in e.Node.Nodes)
{
    node.Checked = true;
}
this.AfterCheck += new TreeViewEventHandler(KmlTree_AfterCheck);

Any ideas?  :-)

Is it possible to get back VS2008 solution for legacy purposes?

Google intends to retire the COM API and instead recommends the use of the 
Javascript API 
(http://googlegeodevelopers.blogspot.com/2010/08/sunset-for-google-earth-com-api
.html). Is it possible for this project to exist without a COM API?

What steps will reproduce the problem?
1. Call IntermediatePoint passing in an origin point
2. Both the return value and origin are now the same value
3.

What is the expected output? What do you see instead?
The origin parameter should not be changed

What version of the product are you using? On what operating system?
Vista 64

Please provide any additional information below.
The error occurs in this line;

IKmlPoint result = origin;

Since the "origin" parm is passed by ref, changes to the "result" object 
will change the "origin" object

This is likely a kludge to get around the fact that you cannot create a 
IKmlPoint without the IGEPlugin object. The method should be changed to 
either take a IKmlPoint output parm, or add a IGEPlugin parm to the 
method. The latter is what I am doing with my static methods. 
Alternatively you could potentially add this as an extension method to 
IGEPlugin.

This patch adds support for NetworkLinks.

It includes a previous patch that fixes folder expansion mentioned in
earlier issue.

It uses a previous applied patch that allows fetching of kmlobjects via the
geplugin.

What steps will reproduce the problem?
1. Downloaded FC.GEPluginCtrls_3.zip
2. Run WindowsFormsApplication1.exe
3.

What is the expected output? What do you see instead?
The GE plugin is not loaded. Instead, I get the following error message:
"FC.GEPluginCtrls \n Plugin failed to load".

What version of the product are you using? On what operating system?
GE version: 5.0.11337.1968 (beta)
GE Plugin version: 1.2.141.5 (same file version as GE)
OS: Microsoft Windows XP x64

Please provide any additional information below.
From what I could see, the crash happens within the 
'google.earth.createInstance("map3d", initCallback, failureCallback)'
javascript call, within the init() function.

This patch adds a public property that sets or gets the tcp port to listen
on server startup. If a port number of zero is provided then the next
available tcp port assigned by Windows is chosen. The assigned port number
is then available through the public port property.

You seemed to close this issue pretty quickly as a no-fix. On the project 
description you write "The library uses a late binding model to the COM Google 
Earth Plugin Type Library (plugin_ax.dll)." But in your response you say the 
project doesn't use the COM API (issue 35). Your response was "this project 
doesn't use the COM API and never has done..."

As an uncredited contributor to this project (including various patches and 
adding support for NetworkLinks) I am fairly certain the project has at least 
in the past used COM API to access various KML types etc.

Now, I am not sure what Google means when they say they are removing COM 
support but I suspect it will have a direct impact on "late binding model(s) to 
COM Google Earth Plugin Type Library". 

Isn't this worth at least discussing?

What steps will reproduce the problem?
1. Open local kml file with GEToolStrip
2. Click the reset button
3. Try to open the same kml file

ie = 6.0.2900.3676
api = 1.004
plugin = 5.2.0.5920

Inspection of the code reveals that FetchKmlLocal does not close the 
FileStream.

What steps will reproduce the problem?
1.Use a KML file with an IconStyle referring to a local file icon like this:

<Style id="AirportStyle">
      <IconStyle>
        <color>FFAACD66</color>
        <colormode>normal</colormode>
        <Icon>
          <href>V:\WORK\AppTest\Config\Symbols\AIRPORT.png</href>
        </Icon>
      </IconStyle>

2. This file works in Google Earth, but not with the plugin, I guess that's
because of the file / url difference 
3. With URLs the icon is found normally

What is the expected output? What do you see instead?
I'd expect to see the icon (taken from the local file). Maybe it's the same
difference as FetchKml and FetchKmlLocal

What version of the product are you using? On what operating system?
Latest source code, win XP pro

Please provide any additional information below.

What steps will reproduce the problem?
1.Load a kmz file with the method FetchKmlLocal()

What is the expected output? What do you see instead?
Nothing append

What version of the product are you using? On what operating system?
latest on win 7

Please provide any additional information below.
in the method there is a test which excluse all files except .kml file. What 
happen if we simply allow also kmz files ?

What steps will reproduce the problem?
1. Run the sample program
2. Notice checkboxes next to each node in the GETreeView.
3. Using the sample Test Application, enter Design Mode for the dialog
4. Click Edit Items on the GEToolStrip control. Add a button control to the 
tool strip controls and click OK
5. Run the sample program
6. After all of the sample items are loaded, notice that the checkboxes are 
missing from all nodes.
7. Get an original copy of Form1.Designer.cs, and replace the changed version 
of this file. 
8. Run the sample program
9. The checkboxes are back next to the nodes in the GETreeView.

What version of the product are you using? On what operating system?
Using the latest version (Released on April 7, 2011). 
Windows 7

Please provide any additional information below.
I am not very familiar with the library at this point, since I just found it 
today. However, I was able to reproduce this with great regularity once I 
figured out the steps. 

What steps will reproduce the problem?
1. Update to the latest plugin 
2. Run the application
3. Crashes on init

What should this feature enhancement do?
Calculate a destination coordinate given a distance and bearing.

My implementation, cleanup as required:
        public Coordinate Destination(double distance, double bearing, bool kilometers = false)
        {
            double lat1 = Maths.ConvertDegreesToRadians(this.Latitude);
            double lon1 = Maths.ConvertDegreesToRadians(this.Longitude);
            bearing = Maths.ConvertDegreesToRadians(bearing);

            if (kilometers)
            {
                distance = Maths.ConvertKilometresToMiles(distance);
            }
            double DoverR = distance / Maths.EarthMeanRadiusMiles;

            double lat2 = Math.Asin(Math.Sin(lat1) * Math.Cos(DoverR) + Math.Cos(lat1) * Math.Sin(DoverR) * Math.Cos(bearing));
            double lon2 = lon1 + Math.Atan2(Math.Sin(bearing) * Math.Sin(DoverR) * Math.Cos(lat1), Math.Cos(DoverR) - Math.Sin(lat1) * Math.Sin(lat2));

            return new Coordinate(Maths.ConvertRadiansToDegrees(lat2), Maths.ConvertRadiansToDegrees(lon2));
        }

[not really an issue as such]

How would you compare this with the Google Earth COM API?
http://earth.google.com/comapi/index.html 

Given VS kicks out a PIA for this, isn't that all the managed code wrapper 
we need?

In latest SVN, trunk/FC.GEPluginCtrls.csproj shows External.cs under
Interfaces folder. i.e.

{{{
  <ItemGroup>
...
    <Compile Include="Interfaces\External.cs" />
}}} 

However, it really sites directly under trunk, i.e. trunk/External.cs

The Software is a winform DESKTOP APPLICATION, BUT the nature of the 
WEBBROWSER forbid the local file(image) access.

Is it kind of a conflict?

What steps will reproduce the problem?
1. down load and unzip FC.GEPluginCtrls_2.zip 
2. ran WindowsFormsApplication1.exe
3.

What is the expected output? What do you see instead?

Same as screen capture on the web page. Instead, I see Black Screen on the 
right.
What version of the product are you using? On what operating system?
I ran this on Windows XP

Please provide any additional information below.

What steps will reproduce the problem?
1.
Run the Program with 5.0 plugin.
2.
stop at geplugin.getapiversion() at GEWEBBRWOSER.
Exception thrown.

What version of the product are you using? On what operating system?
5.0 PLUGIN, WINDOWS VISTA, IE 8

I traced the var, and found that the some problems with GEPLUGIN:I use the 
debug tool the check the property of GEPLUGIN, It crash at "LAYER_ROADS".
I used other PLUGIN.HTM I found from other sites, then No problem. But of 
course, I cannot have the functionality of the project.

Hi Fraser,

First of all thank for all your great work with this library!

What should this feature enhancement do?
Is there a way to to add 'styles' to a placemark created with your library as 
i'm used to working with the GEPlugin like the following:

KmlStyleCoClass style = m_ge.createStyle("");

//do style stuff....label color, icon, iconscale etc  -> set the style to pm:
placemark.setStyleSelector(style);

BR,
TKM

[deleted issue]

It works fine as a winform. I am wondering what should be changed to port 
browse control to Silverlight 3. Basically you can't reference browse 
control assembly directly in silverlight.

I know there is a MS silverlight map control which only works with VE. I 
think GE plugin silverlight control will benefit a lot.

Please guide. Thanks!
