You can't change their UI.
No, that's a lie; you could install Greasemonky, write some JavaScript and remodel the page everytime it's loaded to your liking.

Did you read the Google Map API, and register for a key to use it?
The google maps web site has a complete how-to on how to use the mapping system complete with pre-written code.

Well, I can't see your code, but the exception is pretty clear. You have a column called EmailID and it doesn't belong in the database table Table.
|
|
|
|
|
The error is simple.
The column Emailid does not exists in the table from which you are fetching the data.
If it exists then check the spelling. There might be problem in your SQL query also.
Thanks.

Hi All,
I have used channel factory class to get wcf service proxy object, after executing the methods in the service, its taking too long to give the result and aborting with web service has closed the connection. Is there any way to close the ChannelFactory connection once after its done executing the methods.
Its very urgent please help me.
Below is my code for getting the channel.
Public Function GetChannelForService(ByVal source As String, ByRef loger As Logger) As IStayAtWorkService
Dim channel As IStayAtWorkService = Nothing
Dim objStayAtWorkService As IStayAtWorkService = Nothing
Dim factory As ChannelFactory(Of IStayAtWorkService)
loger.log(1, "Begin GetClaimRequestContactFromSession, StayAtWorkServiceAddress" + source)
Try
Dim result = String.Empty
'Get the channel from WCF
Dim address As EndpointAddress = New EndpointAddress(source)
Dim binding As WSHttpBinding = New WSHttpBinding()
binding.MaxReceivedMessageSize = 2147483647
binding.ReaderQuotas.MaxArrayLength = 2147483647
binding.MaxBufferPoolSize = 2147483647
binding.SendTimeout = New TimeSpan(1, 1, 1)
binding.ReceiveTimeout = New TimeSpan(1, 1, 1)
'binding.CloseTimeout = New TimeSpan(1, 1, 1)
'binding.OpenTimeout = New TimeSpan(1, 1, 1)
If factory Is Nothing Then
factory = New ChannelFactory(Of IStayAtWorkService)(binding, address)
ElseIf factory.State = CommunicationState.Closed Then
factory = New ChannelFactory(Of IStayAtWorkService)(binding, address)
End If
channel = factory.CreateChannel()
'Dim tempObj As IStayAtWorkService = channel
'objStayAtWorkService = DeepClone(tempObj)
'If (Not factory.State = CommunicationState.Closed) Then
' factory.Close()
'ElseIf factory.State = CommunicationState.Faulted Then
' factory.Abort()
'End If
Catch ex As Exception
loger.log(1, "Catch GetChannelForService, Excelption : " + ex.ToString())
Finally
End Try
Return channel
'Return objStayAtWorkService
End Function
Thanks & Regards,

This article says the best way is to load the class is in a constructor, so it's only loads once, and not the service itself, in which it loads a new instance of the class each time the service is called.
So your speed or crash issue is probably because the garbage collector is not able to clean your memory heap, and does not know which area or segment of the heap to clean or deallocate, and keeps using the last allocation of the instance. I would consider that leaking memory on the server.
I may be wrong, feel free to school me on this.
I know how to write constructors and deconstructors with callbacks in c++, but I'm kind of fuzzy on it for asp.net. From looking at this tutorial, it looks the same if your coding in csharp.
You'll probably have to write a new class using the constructor, and perhaps add a deconstructor when your totally done with the class. Then come up with a new way to call the service.

So you create the class based on a session.value, when done, destroy the session. That could of been placed in the new and finalize
Feel free for anyone to tweak it and make it better, I had 15 minutes to kill before leaving today.

It's not tested at all, nothing to test it on.

That was the purpose of the sample, just something to feed off of, so you can create your own solution.
I'm surprised that no one jumped in to refine my sample code.
Good Job!

I would like to know what I can check on to view the performance of a 2010 web form C# application. To accomplish this goal, I have the following questions:
1. Is there a web page analyzer that can be run against the web form applicationso that we can see exactly what is being loaded and what takes the most time to load?
2. Can view selectively turn off session state? If so, how do you accomplish this goal?
3. Can I selctively turn off view state? If so, how can I selectively turn off viewstate? Are there cases where I need to keep view state around? If so, when do I need to keep viewstate setup?
4. Are there other items I can check on to monitor the performance of a website? If so, hwat are they and how do you use them?

Hi all,
I have a requirement like this. A table has a set of say 10 fields. The user wants to search the table using any combination of fields. Instead of adding a fixed number of textboxes and labels (10),I have been thinking about creating a composite control TextBoxList..which would probably inherit from TextBox..Label..CheckBoxList. So now I ll be able to add any number of textboxes with labels by passing a parameter. I have just started reading about composite controls in asp.net 4.0. Any suggestions on how to build it would help me a lot. Thanks.
P.S. My First Post Here..

Are you trying to build a "where clause" for your table?
The idea would be to pick a field, pick a comparison operator (< = >), then a value and build upon it with ANDs and ORs.
The result would be something like:
field1 > 'A' and field2 = 100
Lots of examples on how this is done can be found on the web.
Good Luck.

Thanks for your interest and time. Yeah. I am trying to build a 'where' clause. But am not thinking about the dynamic SQL query, atleast not yet. My post was more about receiving the values to be used in the 'where' clause.
Suppose I have 10 fields to be used in the 'where' clause. I would need 10 labels and 10 textboxes on the page. Instead of that, I was thinking about creating a composite control - TextBoxList (Which would be similar to a CheckBoxList control). TextBoxList would have a Label and a TextBox. So now if I add a TextBoxList to my page, design would be efficient right.? I can add any number of labels and textboxes by passing a single parameter to the control and also have them arranged automatically. I needed some suggestions on creating this TextBoxList, as I am very much a new born in the ASP.NET world.

you can create c# class library in a folder (let it name be htmlhelpers) and put a method which returns a string holds the input u need like this
"" and so on
this method must be extension method < extension()>_ so u can use it into ur html code
in the view page u just have to inherit the class u wrote and use the method which return this string .

Hi,
I have an asp.net web page, in which the in the code behind few methods are defined, they are declared as "webmethod", these web methods are calling some WCF methods. These webmethods are being called by some web page using AJAX.
It was taking too long execute web methods. I kept a loggin there, intially WCF service was throwing some exception. Then I have set the Send Time out property for the binding. That problem was resolved. But still the execution is taking a lot of time.
Do I need to set the timemout property web methods also, if it is, then how can I set it. Because it is not a web service but it is web application and web page which is having the <webmethods> in it. In that case how can I set the time out propery. And Which time out it should be like "SendTimeout" or "ExecutionTimeout" etc.
After waiting for a long time, it is giving the following error in the dialog box
---------------------------
Microsoft Visual Studio
---------------------------
Unable to process request from service 'http://xxxxxxxxxxxxxxx/xxxxxxx.StayatWork.Service/StayAtWorkService.svc'. Catastrophic failure
---------------------------
OK
---------------------------
Please help me in doing so, its very urgent.
Thanks & Regards,

1. you have a aspx web page
2. with web services in it
I'm lost here on your description.
A web service page is usually a asmx page
A aspx page containing javascript can make a call to a asmx page, in json or xml.
I've seen old school asp pages used for web services, using xml
Typical Web Service Header using json for request and response
<WebService(Namespace:="http://www.ice5ommerce.com/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
<System.Web.Script.Services.ScriptService()> _
Public Class ws_classic1
Inherits System.Web.Services.WebService
<WebMethod()> _
Public Function load_RItem(ByVal product_ID As Integer) As String
Other than that, I know the error reflects a huge crash, and the service gave up and sent a response back to the requester. There is no timeout that you can set, it uses http to communicate.
But I don't where the crash is,
Your description sounds like a request to a web service, that made a request to a web service.

No its not asmx page its aspx page in which its methods are added with <webmethod> prefix by adding Imports statement for the "System.Web.Services". These webmethods are calling the WCF Operation Contracts.
Some how may be because of the WebMethods or WCF service methods, its taking long long time for finishing the execution.
I am getting lot of doubts regaring this issue
1. Is the WCF service is timing out, because it is reading the xml files using XMLDocument object
2. Are the webmethods are timing out because this is first I am putting webmethods in the aspx page, I did it earlier with asmx files
3. I am creating the WCF service client using ChannelFactory class, using createchannel method, is it creating lot of channels and WCF service is not able to process and just breaking because when I try to restart the iis also it is taking hell lot of time.
4. Do I have to close this channel factory class object and dispose it, it is how should I do that it is giving object reference null exception and saying that trying to retrieve using disposed object.
5. Then I created a method to clone the clientproxy class (or channel class) to return the cloned object and then dispose the channel factory class. Still the cloned object is coming as nothing, I am using VB.Net.
6. Is there any problem in my architecture or in WCF services, where am I missing.
Please help me in finishing it, its very urgent. Please help me please

I've never used WCF, and don't intend to in the near future. I read up on it just now, and it doesn't seem suited for my needs.
All in all, there are 3 parts, the requester , service and the responder.
1. You have to test the requester, and make sure the request is correct
2. Then test the responder, and make sure the response is correct.
3. You have to test the service, and make sure it doesn't crash from bad input.
Once you have tested all 3 parts, then it should work.
In c++ programming, it's good practice to use an exit code,
0 for success
1 for warning
2 for failure
[Edit]
Other than that, I have no clue. But I have many situations in which I have to walk thorugh the service, or build in more error checking before processing.

Hi,
Yeah its the problem in requester its opening new connection each time it requests. And .Net doesnt close the connection automatically after ending the block.
Either open the connection only when its closed or close and dispose it properly after using it. I preferred first one. Open it only when it is closed.
Its working. Thanks for all your help friend.
