Hi there

I believe the "i" element in complex type element "uv" of your weather.xsd should be of type "xs:string".

E.g. for location SNXX0006, the returned value is "10+".

10+? Wow. Didn't realize it was a string. Weather.com only provides a DTD schema and you can't tell the data type of each field, so I had to make an "educated guess" here and there. Thanks for pointing it out!

Yes, apparently us folks at the equator have it pretty darn warm. ;)

Regarding the png transparency issue, I found this URL that provides a solution.

http://homepage.ntlworld.com/bobosola/pnghowto.htm

Thanks! I'm including this PNG fix with the demo page.

This is terrific! Could your control support forecast information as well as the current temperature? Thanks!

The control has 'Temperature' and 'FeelsLike' properties. I will add 2 and/or 5 day forecast information in the next release.

How would i include this page into my template page (CSK VB)?
I can get the page to work outside my main site, just not sure how to add to page.
Thanks

I am using this weather control in a pet project site I am currently working on and today I ran into a pretty bad error handling problem. I am not exactly sure where the error came from but I think it was due to a DNS problem or possibly network problems where the server is hosted (there were no problems on the local mirrored version of the site). The page errored with a "connection was terminated: could not resolve remote [name? server? I forgot]" error. It was definitely from the weather control, but I'm not sure if it was a DNS problem (not being able to reach the weather service?) or if the service threw an error (unable to reach its database?). The problem only lasted 4 or 5 minutes but I had to remove the control from my page templates in order to get the pages to work. I had similar problems when I tried to work on the site when the server wasn't allowed to hit the Internet. I know that normal usage would dictate that Internet access is required but I think adding another try/catch or something and displaying a generic "Weather Service Currently Unavailable" message would be the way to go.
I have also considered serializing the current conditions to disk (I only check the service every 30 minutes) and using those results if the service is down.

While I'm here, THANKS! This is a great server control, I was a bit surprised (thought I should have known) that, after dropping it onto my ASP.NET page, the page still was still valid xhtml trans. Good job and thanks again.

The control allows you to craft your own markup, so it's your accomplishment that your page is valid XHTML Transitional, not mine. :)

Good point about error handling. I need to do a better job at handling errors when weather.com itself goes down or an Internet connection is not available.

I want to start off by saying, wow,thanks. This is a lovely control, beautifully documented too. I discovered it earlier this afternoon and it's been a joy to work with. I'm modifying the control for a dotnetnuke module of mine, to display the weather conditions for a user, and to allow them to enter a different US zip code. It all works nicely - but after refreshing, the image no longer displays correctly. Is there a reason for this? Here is my code:

Dim wccControl As New UserController
Dim zipcode
zipcode = Trim(Me.txtZIP.Text)

If zipcode = "" Then
If Not (MyBase.UserId = -1) Then
Dim x As UserInfo
x = wccControl.GetUser(0, MyBase.UserId)
wccWeather.LocationID = Trim(x.PostalCode)
Me.lblDebug.Text &= ("Setting locationID from userdata: " & Trim(x.PostalCode))
End If
Else

Dim isvalid
isvalid = IsValidZip(zipcode)
If isvalid "" Then
Me.lblfeedback.Text = isvalid
Me.lblfeedback.Visible = True
Exit Sub
Else
Me.lblfeedback.Visible = False
End If
wccWeather.LocationID = Trim(Me.txtZIP.Text)

Me.lblfeedback.Text &= ("Setting locationID from zip box: " & Me.wccWeather.LocationID)
Me.lblfeedback.Visible = True
End If
wccWeather.DataBind() -- this is where I think it's somehow losing the image path??

It's ok ... found it ;-) I moved the location of the ccimages folder. I'm not sure how the images were found, correctly, for the first time the app loaded, if they were in the incorrect location ... but moving them did the trick.

Rozanne, I'd like to know a little more about what happened there and how you solved it. If it happened once, it's bound to happen again. :)

Looks pretty cool...

I registered with Weather.com and received my PartnerID and License Key and added the anrControls.Weather.dll as a reference along with creating a ccimages folder and copied the images in. My problem is the control says "Weather forecast is not available at this time." Am I missing something? If I put all the controls from the WeatherControl I get errors when running the project.

Thank you.

I suggest you wire its Error event, as I described in a recent post (it's also shown in the sample). If you develop in VS.NET see what the exception message is. Otherwise simply print out the error on the page and let me know what it says.

Can you provide some info how to install yours component to WebMatrix. I try with "Add Local Toolbox Component" and select anrControls.Weather.dll.
An Error occurred: "No valid Web controls were found in the assembly" after that I must delete *.dll from ..\WebMatrix\components folder but when I try to run demo next error occured: Parser Error Message: 'WeatherControlTest.defaultTest' is not a valid base class because it does not extend class 'System.Web.UI.Page'.
Source Error:
Line 1: [%@ Page Language="c#" autoeventwireup="false" codebehind="default.aspx.cs" Inherits="WeatherControlTest.defaultTest" %]

thx
Damir

hi
i ve got a pb in WeatherData.BuildImageUrl method

Assembly.GetExecutingAssembly().GetManifestResourceStream (resourceName) always return null

but i ve got added in weather control project all images provided by weather.com

Any idea ?

I found the problem

The images was not marked as "Embedded Resource" in the weather project.


Another question :
Is there a way to display the next day weather forecast ?

Yeah, these is a way. I need to add a forecast template some time in the future and pull down a different XML feed---one that has a forecast for several days ahead.

First I would like to thank you for posting this excellent control. I have a question on your 'Resolve Weather Location ID'. Is this being resolved locally or via weather.com? If the latter, are you going to make the code to replicate this available? Thanks.

Bob, I was so sure I published the code before... but I guess I didn't. I zipped up the ASPX page and its code behind for download.

In a nutshell, weather.com resolves location ID and returns an XML document with all matching locations.

I am having a problem using your Weather Control. I am getting
Weather forecast is not available at this time. I have taken the URL you had in your code and plugged my values into it and go XML back from weather.com. Any ideas? I also see they images were not included in your download. Will this case this error?

Thanks

Luke, take a look at this post. It explains how you can inspect what goes wrong.

Also, images are embedded in the assembly and get extracted at run time.

Milan thanks for the reply here is what i got for an error.

The Weather control should contain a WeatherTemplate element

Luke

Luke, look carefully through the sample page included in the download. The control should have a declaration of WeatherTemplate.

Ahh I see. Thanks alot for your help.

Luke

I am having a problem regarding my WeatherTemplate. The Weather Control does not seem to be updating my form schema to allow for the WeatherTemplate. The control does still work, but when I make a changed to the control through the designer it deletes my Template. Any Ideas?
Thanks

Luke, I believe someone mentioned it to me before, but I haven't figured out how to stop VS.NET from deleting the template. Not sure why it's happening. The only workaround I can suggest is not to use the VS.NET designer, which is aweful anyway.

Thankyou very much for the link!

We are going to implement this in our website!

Hi, I'm working on a version with days forecast support.
I want it to know how can I do to define equals entries on the xml (for example "wind" for cc and "wind" for first day) and the Generator of .NET doesn't give me this error:

Custom tool error: Unable to convert input xml file content to a DataSet. The same table (wind) cannot be the child table in two nested relations.

I know... the problem is that define equals tables (in the DataSet) with the same name, but how can I resolve the problem?

Thanks,
Gonzalo

Hmm... That's an interesting question, Gonzalo. I imagine there will be a name clash, as you pointed out. I wonder if you need to write your own XmlReader for that.

Wow, thank you so much! You made my day.

Quick question though: Does the control automatically cache the XML to the specifications outlined in the SDK?

Thanks again!

Sam, yes, as the SDK prescribes, weather conditions are cached for 30 minutes for each location (one location in this case).

Great Control! The download is missing the PNG's now.. any chance of getting them put back in?

My bad. They are in now. Thanks for heads-up, Brian.

I have your sample and I am trying a simple page, but cannot get anything other than the error "Forecast not available." I can access the xml page and have a template defined, but I cannot figure out what is causing the error. Even when using VS.net and stopping after initializingcomponent (VB) I still see no error being thrown.

Any help would be great. I would like to write out the error to the page using VB, but have not been successful.

Got my error....
System.Net.WebException: The underlying connection was closed: [...]

I think I have this narrowed down but still do not know how to solve.
The Event viewer show me trying to access http with the IUSR account. My IUSR account will not have permission for this and I need to impersonate. However, when I impersonate the impersonation does not seemed to be used by the weather control.

Joe, have you followed the suggestions in this post to troubleshoot the problem? As far as permissioning is concerned, I'm afraid I don't have much insight into that.

Yes, I followed that post. That is how I determined it was having authentication problems. Has anyone had any success in implementing the with a proxy requiring authentication?

If I was a bit more knowledgable in C# and these controls I might be able to implement the forth coming suggestion and just tell you about it.

I believe some code similar to the below will allow users needing to authenticate to do so. Passing the domain, user, and passsword would be most ideal.

WebProxy myProxy = new WebProxy("http://proxyserver:port",true);
myProxy.Credentials = new NetworkCredential("username", "password", "domain");
FindServiceSoap myFindService = new FindServiceSoap();
myFindService.Proxy = myProxy;

Joe, thanks for the tip. You da man!

New error, but i don't kno wi fthis is progress
System.Net.WebException: The underlying connection was closed: The proxy name could not be resolved

//NetworkCredential nc = new NetworkCredential("user", "pass", "domain");
XmlUrlResolver resolver = new XmlUrlResolver();
resolver.Credentials = system.Net.CredentialCache.DefaultCredentials;
doc.XmlResolver= resolver;

Added these to WeatherData.cs above the Doc.Load. Requires using System.Net.
I tried defining condition explicitly and using DefaultCredentials. Same error both times.

I hope you don't mind me using this as a debug stop. I am hoping to find someone that knows something.

Your product looks great and I hope to use it.

This finally worked

< defaultProxy >
< proxy
usesystemdefault = "false"
proxyaddress="http://proxyserver:80"
bypassonlocal="true"
/>
< /defaultProxy >

The code works just great in sub directories but when i take it to the top parent directory it does not work. Also I tried to use the code as a user control and there seems to be a diconnect again, giving me the standard error message. Does anyone have an idea how to use this in a ASP.NET setting as a user control? Thanks for your assistance!!

Excelent article... In one article i found all i need to know about how to user weather.com feeds in a ASP.NET application.

Thanks!!!

I am trying to use a textbox and a button to get the new zip from the user and trying to assign the value to weaControl.LocationID property. The problem is the first time I click the button no change occurs, when I click the button again for the second time the control is changing the values. I thougt its problem with my .net framewrok, but everything else is working fine.
Example
If I enter a zipcode 10001 in the text box and click the button no change occurs, the second time I changed the zip to 73301 and click on button, the control displayed the information for zip 10001. for your reference I am providing the code I wrote in the code behind.
Private Sub ZipButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ZipButton.Click

If ZipText.Text "" Then
Weather1.LocationID = Trim(ZipText.Text)
Else
Weather1.LocationID = "10001"
End If
Weather1.DataBind()
End Sub

Could you make a light version of this component (without png images in dll). This dll is to large

No, because you'll have to manage images yourself which would make usage of this component awkward. I'd rather keep them embedded.

hi,
when i tried to use ur custom control in my aspx page,it is displaying as "Weather forecast is not available at this time"...

I registered with Weather.com and received my PartnerID and License Key and added the anrControls.Weather.dll as a reference

when i dubeg the custom control code ,i noticed these specific below line in "Weather.cs" file

ITemplate template = this.WeatherTemplate;

this "template" variable is getting null,so it is throwing error as "Weather forecast is not available at this time"

What was suppose to be valued in that "template" varibale..
plz reply me with some soultion to deepak.ramaiah@hotmail.com

my last question ,is there any webservice from wether.com or from any organisation which can display us wether forecast of world..
if there is any such webservice,plz let me knwon...

I am using VS.NET 2003

Thank u
Deepak

Deepark, please re-read the article. It talks about the web service at weather.com you are looking for. Their feed gives you enough information about any location in the world.

So can this be applied to Windows Forms? Maybe I can present this data to controls in a Panel?

Tryst

Trystan, I distribute this component with source code. I think it should be possible to turn it into a WinForms control. I'm just not familiar with that side of control development.

Very nice control indeed .... how long before your control will support any forecast information? How soon will a release be available that will support forecast information?
Thanks

I don't really have a time frame for this. I make my code available for free, so if anyone wants to extend the control it'd be great.

Hi,
when i used the custom control in my aspx page,it is displaying as "Weather forecast is not available at this time"...

I registered with Weather.com and received my PartnerID and License Key and added the anrControls.Weather.dll as a reference

Nice control. I am having a problem and others too, I see. The control works without any problems on my development machine. On root level pages as well as sub folders. However, when I upload the files to the live site, the root level works but the sub-levels do not. Any help would be greatly appreciated.

Saju, Michael,

Take a look at this post for troubleshooting tips. Also, make sure the folder where images go has write permissions granted to the ASPNET account (NetworkService in Windows 2003 Server).

Wel let me start by complementing you on a very handy component.
But i have one question. How can i display more than 1 day at a time.

It takes a different query to the weather.com web service to get a forecast for several days. I don't really plan on doing it, but if anyone wants to implement it, please share. :)

I'm using your control in a client's intranet site and they love it. Now they would like to see the forcast along with the other data and I'm trying to accomodate them but I'm running into a problem. I took your code and am using it as a framework and added the forcast elements from the Weather.com sdk to the .xsd file and am in the process of adding the properties to the dll in order to display them in the web page. The problem I'm running into is that dataset returned from Weather.com has data for the stuff like cc, flik etc. but it's showing no rows for the stuff that I added day, hi - etc.

I would appreciate any suggestions/assistance as the documentation from weather.com is pretty poor.

Thanks

I just downloaded your control and am playing around with the weathercontroltest version. I have added a text box so that a user can enter a new zip code. However, hitting subit does not change the data displayed. Can you let me know what I am doing wrong?

I am using the code below:

Protected Sub btnZip_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnZip.Click
Weather1.LocationID = txtZip.Text
Weather1.DataBind()
End Sub

It seems like it should work, but I have had no luck. Thank you for the help and for the great work.

Brett,
I think the problem is with the page life cycle. I found the solution but I think that my solution isn't the best way to do it. Anyway, here is how I solved it:
When the user hits the btnZip, read the txtZip and store it somewhere (for example in Session) and redirect to some other page (for example test.aspx). On test.aspx in Page_Load method redirect back to your first page and in the first's page Page_Load method set the LoacationID.

This is just a fantastic control. I got the current weather displayed on my site, but I now need the forecast data as well. Id this even possible iun the current version? The zip file I downloaded did not contain any documentation. Any help would be greatly appreciated. And again, thanks for the great work!

Leon, please see this comment.

Does anyone know the steps needed to install and use this weather.com control.

I have so far done the following:

Added anr.Controls.weather.dll to the bin folder

Added a reference to anr.Controls.weather.dll

Added the control to my page

Added the PartnerID and License Key

Added the LocationID

Added the ccimage folder and files to my project

But I still get the 'Weather forecast is not available at this time. ' when I run the app.

I appreciate any help,

Charles, see this post. I exposed an error event which you can tap into and see what's going wrong.

Decided to go another route and did the forecast part myself.

here you go...

Very cool!

Could you please help me to find the location ID of Singapore.

Thanks!

Looking for the responces...

Very strange, weather.com won't give me a location Id for Singapore either. :(

Try "SNXX0006". If it doesn't work, pick one of these locations.

That's fantastic.

Thank you so much.

Hello,

First, I want to thank you for putting this control together and documenting it.

I have VS 2008 and tried to compile your control but I get two errors:

Error 1 The namespace 'anrControls' already contains a definition for 'Weather' weather.Designer.cs Weather
Error 2 The namespace 'anrControls' already contains a definition for 'Weather' WeatherDataError.Designer.cs Weather

Do know what is wrong?

Many Thanks, Peter

Awesome control, nice man.
