We have an information box on our map, and the user can select its location: upper right corner, lower left corner, etc. Is there a way to place a layer in a static location on the control, not relative to map coordinates?
Thanks,

Static Location for Layer
Hi Dib,
Thanks for your question!
I am not sure I understand your question. A layer is a container for features, and does not have location attribute so there would not be a way to place a layer at a specific location. Could you perhaps elaborate on what you are looking to achieve?
I want to have a information box on the screen. The user can select where it is to be displayed (upper right corner, lower left, etc).
Hello Dib,
The information box you are using is a control or a polygon? If it’s a control, why are you want to use a layer to put it?
If you need a polygon to show this box, you need know what’s the size of the box, then translate the size to the world coordinate and set as boundingbox to the layer, because the layer does not has the width and height property, layer always fit the full map but you will use boundingbox to control how big you want to show.

Gary
OK, I figured out that I can use a LegendAdornmentLayer for what I want to do, but there is a problem. In creating the LegendItems, I create a TextStyle with a font size. However, when the legend draws, the text seems to scale based on the width of the LegendAdornmentLayer object. Is there a way to keep the text size from scaling?
Hello Dib,
Sorry for the inconvenience, the LegendItem text style does not obey the style setting is a know bug, we are working on that. Once we fixed it, you can update to the newest version and everything will be ok.
Regards,
Gary
Gary,
Is there a timeline on fixing the LegendItem text scaling issue?
Hello Dib,
Sorry for the long time waiting, I have sent a email to get the newest status of this issue, I will let you know as soon as I get the news.
Regards,
Gary
Gary,
Is there an update on this? If not, I need to start working on another solution for an on-map information box. The legend item seems to be a great solution, but without the proper text scaling I can’t get it to work.
Thanks
Hello Dib,
Could you please try the newest dll 6.0.170.0, I get the news we have fixed this problem.
Feel free to let us know if you still meet the problem.
Regards,
Gary
Downloaded .170 and referenced it (DesktopEdition and MapSuiteCore). I am now getting an error on this line of code:
layerWindElipse.InternalFeatures.Add("Polygon34k", New Feature(BaseShape.CreateShapeFromWellKnownData(polyText)))
When I switch back to v6.0 DLLs, it runs as expected. Do I need to do anything else when using the daily builds?
Hi Dib,
Can you supply the exception you received?
Please also let us know if you are using the 6.0.170.0 (Development) or the 6.0.0.170 (Production) builds.
Downloaded Desktop Edition Full .175 this morning, and it runs. However, the text scaling problem still exists. When I change the width of the LegendAdornmentLayer, the size of the text changes with it. The wider the layer, the bigger the text. This doesn’t occur with changing height, only width.
Dib,
I am not sure that you downloaded the version with the fix Gary mentioned.
Note that we have a 6.0.170.0 and a 6.0.0.170. The third and fourth values of the version number are different.
Builds with a value other than zero in the third value are Development builds = 6.0.170.0
Builds with a value other than zero in the fourth value are Production builds = 6.0.0.170
Any changes made to the control to resolve the text scaling would be found in the Development 6.0.175.0 version not the 6.0.0.175 version.
For more information on our Release Cycle and version number schema please see: wiki.thinkgeo.com/wiki/Map_S...ycle_Guide
Please try the 6.0.175.0 version and let us know if this resolves the scaling issue.
Details, details. That makes sense. DLed 6.0.175.0. When I run it, I get a evaluation expired error:
An error occurred creating the form. See Exception.InnerException for details. The error is: The evaluation has expired. Please contact ThinkGeo for purchasing option or an extension to the trial.
We have a full version license, and I am only seeing this with the development build, not the production build. Is there something I need to change on my end to get this to work?
Thanks
Hi Dib,
I have some additional details for you! You downloaded the Evaluation Version of the Development Dlls. You need to download the Full Version of the Development Dlls.
In the Customer Portal there are two sections: My Product Downloads and Evaluation Daily Builds.
You can download the Full Edition Development Dlls from the My Product Downloads - Daily Development Builds section of the HelpDesk site.
Went to My Products Downloads, DLed DesktopEditionFull6.0.177.0DllPackage.zip, extracted, and referenced DesktopEdition.Dll and MapSuiteCore.Dll. Now, when I run the app, two things occur: 1) Nothing displays on the map at startup. For this, there may be an exception being swallowed somewhere in the code, and 2) when I click to show a storm, which creates polygons and lines, I get ‘well known text is incorrect’ errors. This could be due to the map not initializing correctly in #1, but I don’t know of a reason why the map would no longer initialize or display correctly.
Here is the full text of one of the errors, and some examples of the text that was used to attempt to create the shapes. Note that this code/text works when running against the current release:
System.ArgumentException was unhandled

Am I doing something wrong when referencing the Dlls? Do I need to reference additional ones due to the development nature? Are the incorrect text errors due to the failure of the map to initialize at startup? If so, what would be causing the map to do that, that is different from the current release?
If you need more info, please let me know.
Hi Dib,
You are now experiencing the possible issues that can occur with Development - type dlls!
With the 6.0.36.0 version we made a change to what Geometry Library that is used by default.
This is all explained at the following link to our News and Announcements section of the Discussion Forums:
gis.thinkgeo.com/Support/Dis...fault.aspx
The main issue is that with the 6.0.36.0 and newer versions we are defaulting to the new unmanaged geometry functions that are provided in the SQLServerSpatial110.dll. You will see in your stack trace that there is an Unable to Load Dll message referring to this dll.
So how to get the latest version of the Map Suite dlls to work in your application?
The easist way would be to set your application to use the Managed GeometryLibrary that was the default before the 6.0.36.0 version.
You can do this with the following line of code:
BaseShape.GeometryLibrary = GeometryLibrary.Managed;
All set, all good. Thanks for the help
You are welcome.
