comment Running OpenLayers in .NET 4.5 breaks
I think it's most likely you're passing a bad argument, or missing one altogether, when initialising the map or other OpenLayers components. How is overviewMapControl defined? You might want to use the uncompressed version of the OL library and debug around the line that throws your error. Follow the call stack back up until you find a line of your own code, then inspect what you're passing with it.

comment What does 'DBMS table not found' message mean?
@DevdattaTengshe I think you should encapsulate data concerns at the data layer. Use an OLE connection to query a view that handles all your table relations. In a perfect world your GIS shouldn't need to know how your database schema is structured.

comment ArcGis Javascript api detect one second hover
hmm good point, I figured because you weren't creating a closure the scope would be lost

comment ArcGis Javascript api detect one second hover
There doesn't seem to be a standard for the return value of setTimeout or setInterval, so I don't think there's any guarantee it won't be 0. So you probably want to do something other than a coercive truthy check in if(timeOutAction), e.g. don't define timeOutAction and check if(typeof window.timeOutAction === 'undefined'). Also (and more importantly) var timeOutAction won't be in scope when your onMouseMove handler is executed - it's tied to the function but your handler will have global scope

comment Given a lat/long point, determine if it's land or water?
you don't say how your users will interact with the data (will that be QGIS too?). Depending on your application you might just colour water blue and land green, then inspect the colour of the pixel under the mouse pointer. Also, why can't your users answer this question themselves?

comment Moveable ESRI / ArcGIS Identify Popup Window (Dojo)
I previously thought about doing something similar, but making the popup moveable is only part of the problem - the window points to the location it references using one of these images: serverapi.arcgisonline.com/jsapi/arcgis/3.3/js/esri/dijit/… Unless you want to get into a rather sticky problem you will have to live with the popup no longer pointing to the correct location

comment Can I download a layer displayed on the google api?
I'd guess you're dealing with a WMS. A quick trawl through the site's JS source should give enough clues on how to reference it within a desktop GIS suite. However assuming they are only providing WMS (or similar) and not WFS (or similar) you won't be downloading raw data, only its styled representation in image tiles.

comment Using Query Layers with ArcGIS Server 10.0 for Java on Linux
I don't envy you - you really picked the most difficult ESRI configuration scenario ever! I had some problems with query layers in 10.0 that never got resolved (e.g. gis.stackexchange.com/questions/34789/…) but when I moved to 10.1 everything magically worked. Is that an option?

comment Geoserver 2.1.3 no GetFeatureInfo-Response when multiple Features found on same location within same layer
Is this a custom freemarkers template? If yes what happens when you don't use it, or use a different template? Do you get a different result if you change your layer's symbology?

comment ajax not working with postgresql
it being the same file makes no difference, you're still just dealing with client requesting from server over HTTP. Did you use Fiddler or another network debugger? You need to first verify that your request is being sent and that the POST body is what you expect. Fiddler has plenty of tutorials

comment ajax not working with postgresql
do you know for sure that the value is sent? Get Fiddler running and check that your request is indeed a POST and that the value you expect is being passed. Also do you know for sure that the correct PHP script is being called? Change the PHP script to always echo 'something' and check that this gets back to the browser. These kinds of simple steps will turn your big ambiguous problem into one or two small and well-defined problems.
