Very nice!

I really, really like the reduction in memory footprint.  Is this anywhere near what you are going to be at release?  Or is it going to bet better still?

How does one enable traffic and weather on a Winform based app? I see some methods, but I dont see a sample using them. Also, when is the WPF version going to hit?  <grin>

So many questions. <grin>

Mark Merchant was going to get in touch with you about our interest in using this.

Thanks

Paul from THD.

Nikolai,

Thanks, Remember, I am playing with a WinForm app, using the VE3D control, so Javascript is right out. :)

I tried to load the plugins (trees and weather ) you specified above, but I saw no visual changes.  Are they specific to a particular region?  I tried it in both my test app, and the SimpleForm in the Samples downloads.

Thanks again.

Paul

Great, thanks for the samples.

I noticed that with a WinForms app using the GlobeControl, I no longer am able to display information in the lower right corner. With 6.1 I could use the globeControl.Host.WorldEngine.ShowXXX properties to control what is displayed. These properties still exist, but don't seem to control what is displayed. Is there a new interface I am missing?

Thanks,

Torrey

I have another question. I am trying display a set of tiles generated from MapCruncher. Looking at the TerrainImages example, the third method for adding images to the ground seems to fit my needs. I am trying to use the file system rather than IIS to store the tile images. In the connectionParameters for the DataSourceLayerData, I define the tilesource field as:

tilesource\"file://d:\\Layers\Alaska\\%4.png\"

When I add the DataSource I receive an exception stating that "A valid tile request format string was not supplied".

Is it possible to have a tilesource like this that is on the local file system?

If so, how do I format the "tilesource" field of the connectionParameters?

Thanks,

Torrey

So the clouds only appear when you are looking up?  I see them when I zoom down, and change my viewpoint to look sideways, but I dont see them if I am in the air looking down.

Is there any talk about integrating near real time radar, or storm alerts?  If not, is the assumption that we would need to hook into a tile server to feed the data?

Thanks, Neat stuff

Hi, VE3D Team,

I'm trying to bring up the Camera dll sample in a WebBrowser control under a partial trust environment. Have no problem loading and activating the dll from my local machine, but when I issue the Raise Event for the dll to 'jump' the globe to a random location, I get an HRESULT 0x80020101 error from the control.

Any thoughts on what I might be doing wrong?

Thanks,

Clyde

Nikolai,

Happy New Year. Thanks for your reply. I have tracked down my problem more and also realized I could have been a bit clearer with my first message. Here's what I'm up against:

1. Creating a WPF application that has to run in partial trust.

2. Currently have VE hosted in a Web Browser control operating in 2D mode only.

3. VE3D needs to be called based on events taking place in controls other than the control VE3D is hosted in.

4. I can instantiate VE in 2D mode, then call against the VE Javascript API using the WebBrowser's InvokeScript method.

5. If I try to instantiate VE in 3D mode from the WebBrowser's onload event the instantiation works fine but subsequent InvokeScript calls fail with an undetermined HRESULT error.

6. If I try to instantiate VE in 3D by using an InvokeScript call from managed code into the WebBrowser the LoadMap function fails on an "unmanaged code" security permission exception.

7. I was trying to use the undocumented plug-in load methods to get around this problem, but I can't seem to get past the unmanaged code security permission exception. I've tried lots of different options to give myself permission to call unmanaged code but nothing seems to work.

8. I thought that by packaging the map control DLLs in my own assembly I could workaround the unmanaged code security restrictions. But I can't seem to find a way.

Any suggestions appreciated.

Clyde

Nikolai,

Again, thanks for getting back to me. I'm still trying to track down my problem which seems to be related to managed code calling into unmanaged code.

(1) I've separated out the user control with the webbrowser control that host VE3D into a separate assembly;

(2) I've given the the assembly APTCA and suppressed unmanaged code security for the calls into the VE3D javascript API.

Here's the error I get from the error log when I use the InvokeScript method of the web browser control to call the map.SetCenter method of VE3D (note this call works in 2D):

1/16/2009 4:44:13 PM : CLR Terminating: True

Nikolai,

If I read the error log correctly it would appear that the VE3D control is accessed via the .NET Remoting Framework, and that between the time of my first call to LoadMap(...) and the second call to SetCenter(...) the Lease on that Remoting object has expired. Am I understanding this error report correctly?

If this is the case, is there a way to extend the lease on the VE3D control?

Clyde

Nikolai,

I want to revise my last message. It appears that the lease being set more than once, so is there any way to prevent this.

Clyde
