Web Forms :: Timeout Error Continues On Long - Running Web App Supposedly Already Configured To Accommodate Long

Jun 16, 2010

I'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

<httpRuntime executionTimeout="9999999" maxRequestLength="2048000" />
<location path="default.aspx"> (the page at issue that's timing out)
<httpRuntime executionTimeout="9999999" maxRequestLength="2048000" />

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:...........................

Web Forms :: Converting Latitude And Longitude Into X / Y Pixel Coordinates

May 17, 2010

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:


I feed data into my heatpoint function using these 2 functions above like this. Here's a set of 4 points:


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.

Web Forms :: Image Button Returns Incorrect Coordinates?

Oct 27, 2010

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)?

Web Forms :: Creating A Map - Unable To Capture The Coordinates By Clicking On The Map?

Mar 25, 2011

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:


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.

Forms Data Controls :: Displaying Embedded Google Map Given Specific Coordinates?

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...

Design A Website / Move The Image Around And It Sets The Coordinates?

Jan 18, 2010

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.
