I want to learn a user's location from his mobile device by web application.
When user opens the website, with the help of a script we will learn if the device has a gps hardware.And if the device has gps hardware what are the current coordinates?
I'm developing my project using ASP.NET
i'm using 4 combo boxes for displaying latitude details.the latitude details are degree,minutes,seconds and north/south.when i select the city in combo box the latitude details from sql server (for that city) should be displayed.
View 1 RepliesI have to do the following.
There is a database (SQL Server) with locations (longitude and latitude values). I need to plot the route on the map (Google or otherwise) based on those locations extracted from database. Plotting lines and map are on ASP.NET webpage.
What would be the most and cost-effective way to accomplish the task above?
I 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!)
No idea what to do: I didn't alter the map code at all!
Is there anyway to simulate a mouse click using X,Y coordinates on a webpage ? Let's for example say I want to simulate a mouse click at page position x=400, Y=300. How Will I be able to do it using .net or javascript?
View 5 RepliesLet'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.
View 1 RepliesI 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'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 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.
I recently got a project and i would like to use asp.net to do it . I have to make a program that calculates some coordinates and comunicates with an airplane ( sending data through a radio connection ) . Can I do so with asp.net ? I mean isn't there any restriction in the privacy area? Will it let me send and recieve data to/from an airplane through a radio connection ?
View 1 RepliesI 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...
Refer [URL] .... I want when I click on map to show coordinate in text box it show marker in map I mean below marker:

I'm experiencing a to me mysterious error when sending e-mails through a SMTP-server from an ASP.NET web application. I get the famous error "unable to relay for xxx@yyy.zzz". What's mysterious to me is that when I cut and paste the exact same code that sends the e-mail into an usual .NET Windows Forms application, send the e-mail with this application, it all works just fine. This made me think that perhaps the problem is that the ASP.NET application runs as NETWORK SERVICE while the Windows Forms application runs on a domain user account, but it turns out that I have another ASP.NET application sending e-mail through the same SMTP-server running under NETWORK SERVER at the same IIS, and this application does not experience this problem.
I've further tried to send e-mails through the SMTP-server manually by telnet the smtp-server on port 25 and running the SMTP-protocol manually, and it all works fine. The SMTP-server is not configured with any kind of authentication or SSL.
Another mysterious fact is that the ASP.NET application can send e-mails from an adress within the same domain to an e-mail adress within the same domain, but not to any adress outside of the domain. But the Windows Forms application, that uses the exact same code, can send e-mails from any adress to any adress both within AND outside of the domain.
So to summarize:
The ASP.NET application can send
e-mails from addresses within the
domain to adresses within the domain,
but not to addresses outside of the
domain.
A Windows Forms application running
the same code on the same computer
can send e-mails from ANY address to
ANY address.
Another ASP.NET application on the
same IIS running under the same
account (NETWORK SERVICE) can send
e-mails using the same SMTP-server
from ANY adress to ANY adress.
There is no authentication configured
on the SMTP-Server.
Both the ASP.NET application and the
Windows Forms application utilizes
the System.Net.Mail.SmtpClient class
to send a
System.Net.Mail.MailMessage.
The code that sends the e-mail massage is:
private void button1_Click(object sender, EventArgs e)
{
MailMessage mesasge = new MailMessage(txtFrom.Text, txtTo.Text, "Test mail", txtBody.Text);
SmtpClient client = new SmtpClient();
if (!(string.IsNullOrEmpty(txtUserName.Text))) //Is false since txtUserName.Text is empty
client.Credentials = new System.Net.NetworkCredential(txtUserName.Text, txtPassword.Text);
client.EnableSsl = false;
client.Host = txtServer.Text;
client.Port = 25;
try
{
client.Send(mesasge);
}
catch (Exception ex)
{
txtResponse.Text = ex.Message;
}
}
As far as I can understand, this should be a matter of configuration rather than coding issues.

I have a requirement for building an instant messenger application for the selected user.
I have googled for the solution but without any sucess.My requirement is once a user initiates a chat with another user,the another user needs to get a popup of the chat window,where the two users can start chatting.
we are experiencing big difficulties in the configuration of ASP.Net state service and II7. The service seems not working correctly because when the application pools recycles the applicatio loose the session.If we try the same configuration in IIS6 it works correcly.What is the correct way to configure the aspnet session state service in iis7?
View 2 RepliesWe have an ASP.NET application deployed on 2 Application servers with load balancer server. It is using INPROC state management. The ADO.NET connection pooling is enabled with 50 as minimum connections and 100 maximum connections.
In Load testing (using load testing tool) when the application reaches to 50 users no more users can connect (login) to application the TPS reaches zero. No errors are logged in application log related to application or database. The sessions are working fine.
Currently, on our production IIS web farm, we host about 15 applications in a single App Pool (Default App Pool). There are two websites and about 13 virtual directories.A colleague has recommended that we change our IIS configuration so each application is a separate App Pool (with identical settings).
Is there any drawback or potential issues to doing this?Is it possible that ASP.NET applications could have been built with the requirements that they are all within the same App Pool?
