Let's say I have a LatLng , is there any way of checking if it represents a possible location within a city? How can I get the limits of a city? I'm using Google Map.

using the bing map API, can I make a server-side call and get lat/long for a given city? I can do it on the client side using JavaScript, but I need something more robust in this case and want to use the server side.
View 1 RepliesI have a zipcode database in mssql which has the zipcode, lat and long. I need to write a query in my asp.net using vb.net to show all records with a zipcode within a certain number of miles.
I have seen calculations to show the distance between two zipcodes but I need to find the ones within say 10 miles or 25 miles.
I have a scenario where I need 2 dropdowns like state and city.City dropdown depands upon on State drop down.Will you please tell me how to achieve it ASP.NET MVC?I found this article but not sure is there any alternate way to do?http://stephenwalther.com/blog/archive/2008/09/07/asp-net-mvc-tip-41-creating-cascading-dropdown-lists-with-ajax.aspx
View 1 RepliesI've developed a web application to accept video file uploads and then pass them to a backend service on an external server. The application runs without error on the visual studio debugging webserver, but once on a production iis 6 or 7 server, yields a timeout error at about a consistent amount of time into handling a large upload. Specifically, it errors in the middle of transferring the video file to the external server, once the application has successfully received it from the client. I'm aware of several timeouts to be configured related to the problem, and have done so. The application's web config has been tested with one or both of the following settings
<system.web>
<httpRuntime executionTimeout="9999999" maxRequestLength="2048000" />
</system.web>
and
<configuration>
<location path="default.aspx"> (the page at issue that's timing out)
<system.web>
<httpRuntime executionTimeout="9999999" maxRequestLength="2048000" />
</system.web>
</location>
</configuration>
And within the initialization of the webrequest made to the external server to send the video received from the client browser:
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.ContentType = "multipart/form-data; boundary=" + boundary;
httpWebRequest.Method = "POST";
httpWebRequest.Timeout = System.Threading.Timeout.Infinite;
So with the execution time limits on both the webform as a whole and the connection made to the external server, I'm at a loss for what timeout is left unconfigured, or how to determine such, when I continue to get the following error: Unexpected error executing Brightcove Upload:...........................
I've been struggling for the past couple of days to get this right. I'm in the process of building something that takes a whole bunch of geographic points, builds a heat map from the data, then overlays it as a tile on Google Earth / Google Maps. A bit like this: [URL]
I have all the heatmap functionality nailed using random xy points. The last part is doing the actual conversion to convert my real lat/lng pairs into x/y pixels to be rendered onto the heatmap image. Lets say I the image is 500px x 500px. I know the min and max values for the lat/lng points, so technically I need to divide the spread between the pixels to get a pixel value for each degree based on the top left pixel of the image (0,0). I've been through so many examples, but I just cant get them to work. The last one I tried was this:
[Code]....
I feed data into my heatpoint function using these 2 functions above like this. Here's a set of 4 points:
[Code]....
The problem I get is that the result is the same for all the points - they all get plotted to exactly the same point. Now, the data is fairly localised, so I dont really need to take the curvature of the earth into consideration.
I have an ImageButton which sometimes returns the wrong coordinates when clicked. So far I have seen this problems only on one particular computer but on that system it is consistently out by a factor of about 1.25. The dimensions of the ImageButton are 300 x 450 but clicking in the lower left corner returns 374,562. However, if I raise a button click through code the correct region of the button is accessed and the correct coordinates can be recovered. The browser is IE running under XP SP3. On other computers with the same browser and operating system there is no problem but I don't know how widespread the problem could be. It is not affected by altering the screen resolution. Has anyone encountered this before? Is there a way to test and calibrate an imagebutton (without asking the user to click somewhere special first)?
View 4 Replies consider the following:
1- My web site has a map. The picture format of the map is jpeg.
2- Each user can add a node in the map by clicking on it.
3- After clicking the coordinates(X and Y) of clicked area is captured
4-Coordinates are saved in the data base
5- Whenever the page containing the map is loaded, for each coordinates stored in the database a small circle (ImageButton) will
be added to the map
I have two solutions for it:
1- Using a ImageButton as a map. I can capture the coordinates of the clicked area as follows:
protected void ImageButton1_Click(object sender,
ImageClickEventArgs e)[code]....
The problem of this solution is that the programmatically added nodes are not visible
2- As an alternative for ImageButton I can use a panel to display the map (BackImageUrl="~/Images/map.jpg").
after creating the btn programmatically I use the following code to add it to the panel:
Panel1.Controls.Add(btn);
Hear the problem is that I cannot capture the coordinates by clicking on the map.I need to enable the user to add the nodes to the map and view them in a single interface.
I was wondering if anyone has done this. I'm writing an application which parses latitude and longitude into a database. When presenting this information to users I would like them to be able to click on a button which would show them the location in google maps.
Alternatively I could just give them the link to google maps into which they can click on and open a new browser window...

View 1 RepliesI started a website based on the NerdDinner source code, everything worked fine (more or less) but whenever I post an event, it ends up on the exact same coordinates on the map regardless of the address (Somewhere in the Gulf of Guinea!)

I have a specific requirement of extracting text and images from a specific area in a pdf file.The area might be a selected or highlighted or from a given set of coordinates.
When i went through, all the approaches are to extract images and text entirely from the PDF on not in a specified location. I tried with iTextSharp,Syncfussion,Apose but couldn figure out a better approach for this.
I am trying to design a website in asp.net (just learning) and am having trouble positioning div's on the .aspx page.
I normally design in dreamweaver where you can move the div around freely and it sets the x and y coordinates for you but I am having trouble positioning an image.
Do you have to type the x and y coordinates in yourself in the code behind or in the css or is there an easier way where you can freely move the image around and it sets the coordinates.

My site is going to display content based on a city. So, if a user comes directly to my site, I am going to default them to say for instance:
www.mysite.com/cincinnati
I need to be able to handle two scenarios here. One, when they come directly to my site ('/'), I need to somehow redirect to my default city and 2, show an error page if they type in an invalid city. Any thoughts? I saw the route constraint, but how do you deal with invalid scenarios like showing an error page when the constraint fails?
I'm trying to write a Javascript Zip Code lookup utility.
1) The User will select a State from a drop down.
2) The City Drown Down will then be populated based on the State selected
3) A textbox below is then populated with the corresponding Zip Code(s) based on Selected State and Zip Code on an ASP.NET page.
Problem: I get the error Request() is not defined which causes the application to hault when a State is selected.
What should I cahnge in the following code?
<script language="javascript">
var request = new Request();
var url = "";
function getZipCode()
{
request.GetNoCache(url + "getZipCode.aspx?City=" +document.getElementById("drpCity").options[document.getElementById("drpCity").selectedIndex].value+ "&State=" +document.getElementById("drpStateSearch").options[document.getElementById("drpStateSearch").selectedIndex].value,
function(result)........
