I've run some tests using a slight modification of the Map Extent and Mouse Coordinates sample, using different browser sizes with either the dynamic or tiled version of the same service. The reports the X and Y min/max as well as the scale of the map. I changed the size and shape of the window for each test. You can run the same code, changing the dimensions of the browser for each one. For each dynamic version, either the X Min/Max or the Y Min/Max are exactly what is used in the Extent tag. You'd have to get the browser proportions exactly right to get both X and Y extents to match up. For the tiled versions, notice that while the X and Y extents are not what you put in, the scale of each window is what the scale is shown for the tile LODs (see the map service page for them). <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"                xmlns:s="library://ns.adobe.com/flex/spark"                xmlns:esri="http://www.esri.com/2008/ags"                pageTitle="Map Extent and Mouse Coordinates">     <!--     The current extent of the map is available directly through myMap.extent.     Similarly, the current scale is myMap.scale.         Other properties easily accessible is myMap.         To get the current coordinates of the mouse cursor, you can add an event listener for "MOUSE_MOVE"     on the map.

Think of it this way. Say you've set the extent so the X difference is 100,000 units. You've set the size of your map to be 1 unit wide, which makes the scale of your displayed map 1:100,000. If the tiled layer is set up with the Web mercator standard levels of detail at 1:144,447.638572 and 1:72,223.819286, the extent of the map will have to change to fit one of those scale. When you're using tiled layers, you cannot set arbitary scales, but have to use the pre-determined scales. If you're using only dynamic layers, you can set any scale you'd like. ... View more

Hi Daniel, I guess I'm not understanding your issue. If I just open the form using MyForm.Show(), then it appears in front of the ArcMap window. If I click on ArcMap, then the ArcMap window will move in front of the form. I can click on the form in the Taskbar to bring it back in front of ArcMap. I work in NOS in the Biogeography Branch. I think we might have crossed paths in working with data in the Gulf of Maine. ... View more

This is more of an issue with resolution of the basemaps you're using and the size of their tiles. Tiled map services will show the data at a specific scale, which is dependent on the size of your map. If the extent you've designated doesn't match the tiled service's scale, I believe it zooms in to a smaller extent. You'll be able to have the precise extent when using a dynamic service, but tiles services are a bit more finicky. ... View more
