Debug your code and step through into your data layer to see what's actually failing, check the connection string it's finding, etc.

This is the first I've used a Web service and I'm having some trouble in getting the return data from the service I'm calling.
The Service is defined as follows:
Public Function CheckSeats(ByVal scheduleID As String) As Data.DataTable
And I consume it as follows:
Enrolment.EnrolmentService MyEnrol = new Enrolment.EnrolmentService();
seatTable = DMyEnrol.CheckSeats(Session["CourseID"].ToString());
Where seataTable is declared as a System.Data.DataTable.
I get the following error however when I try and build the solution:
Error 2 Cannot convert type 'Enrolment.CheckSeatsResponseCheckSeatsResult' to 'System.Data.DataTable' C:\Inetpub\wwwroot\_site_v02_04\_site_v02_04\content\SearchResults.aspx.cs 136 25 C:\...\_site_v02_04\
Can anyone tell me how to solve this problem?

You have to dig into the automated code of the proxy that (I suppose) Visual Studio has generated for you.
It is generated from WSDL, which in turn is generated automatically by Visual Studio again when the asmx was compiled.
You should check the WSDL definition of the method, and you should find that the method does return "Enrolment.CheckSeatsResponseCheckSeatsResult" (you can see it as a tag).
Now: proxy is generated to interpret SOAP and XML as they come from your WS, using Attributes (in C#). If you take a look at the attributes you should see that the method is expeted to return such class (that is: intercept that tag). You should also see the definition for CheckSeatsResponseCheckSeatsResult (either as class or tag) and seeing all this you have the opportunity to dim in which point originary DataTable definition was loose.
A trick I can suggest you is to generate proxy dll with C#: it give you more control over the deserialization of XmlResponse from WS.
I am assuming you are conusming your own webservice.
Another trick which may work is to use the IDataTable interface instead of DataTable class. This does not affect automatic serialization but may restrict opportunities of "fancy" code by autogeneration.
Hope this should help

I am trying to make copy a text feature by using Javascriot and I wrote a function for it::
function copyData(field)
{
field.focus();
field.select()
Copied = field.createTextRange();
Copied.execCommand("Copy");
}
But it works in IE only, I want to get it worked in Mozilla, Firefox and Netscape too. What changes should I make for that??
I've used setSelectionRange(start,end) instead of createTextRange(), it only selects the text from the range from 'start' to 'end' but doesn't copy it.
Kindly Suggest!!

I had that problem myself. I have a time field and when i was clicking on Hour/minutes/second, i wanted the 2 representative digit to be selected depending on the position of the click.
My code obviouly didn't work on Firefox as usual 
I found on the web the following code to solve the problem:
function insertAtCursor(myField, myValue)
{
if (document.selection)
{
myField.focus();
sel = document.selection.createRange();
sel.text = myValue;
sel.moveStart(’character’, -myValue.length);
sel.select();
}
else if (myField.selectionStart || myField.selectionStart == ‘0′)
{
var startPos = myField.selectionStart;
var endPos = myField.selectionEnd;
myField.value =
myField.value.substring(0, startPos)
+ myValue
+ myField.value.substring(endPos, myField.value.length);
myField.selectionStart = startPos;
myField.selectionEnd = startPos + myValue.length;
}

media player is not the most flexible utility to use when displaying interactive content. You would be better off using a flash client.

Hello all,
I have designed a dropdown menu with simple javascript code but actually when disabling the "javascript" property from IE, the menu doesn't work. instead i found this site: "http://www.redballoondays.com.au/" which has same dropdown and it works even if i disabled the javascript property from IE.
So can anyone help me in running me menu even if the javascript is disabled in IE.
Thank you
|
|
|
|
|
That website is using CSS rather than javascript for the menu (a much better way). Theres plenty of examples out there on how to do this (I think the dynamic drive site has a few)
|
|
|
|
|
what about this?? this is the script used by the website
but if you have examples for using css in dropdown menus, please mention one
Thank you

My bad, it does use CSS but it only works in Firefox, that script is for IE. I tried the site in IE with javascript turned off though and it didn't work. It is possible to use a pure CSS solution for both IE and Firefox, like I said search for it on google there are examples out there (bear in mind that a lot of them won't work in both!).
Heres one source for starters:

Hi Guys
I am supporting an ASP application, there is a form in this application which have more than 300 fields. Now sometime data fails at the time of submission. There are 6 screens and session variable are being used to save form data temporarily and move between the screens.
Is there any other way to handle such a huge form?
Please do reply ASAP
Thanks
Ajit Singh

A 300 field form is a usabillity nightmare. I'd break it up into multiple forms, perhaps as a wizard ?

True. It would for sure send chill waves down the spine for the user though.

I made a test a while back on how many fields you could have in a form, and it showed that somewhere around 100 fields the browser started acting up. IIRC that was IE 5.0 on Windows 98, so newer browsers in newer operating sytems probably have a higher limit. Still, the limit is not very high, so it's quite possible that you have more fields in the form than the browser can handle.
The way to handle such a huge form is not to. Split it up in smaller forms.
