Here is the GENERAL PICTURE.
1. Open the ASP.NET page on a tablet portable wireless pc.
2. It has a camera view on the right side.
3. Take a license plate photo clicking a button.
4. Convert the jpg type photo to text.
5. extract only the license number from the text.
6. (Optional) Convert the plate number to a barcode.
Is this kind of program even possible?]
I have been messing about with this for hours surely this should be an easy task ....... I have a stored procedured that creates a invoice on a Quotetable one of the parameters is a output parameter Invoice Number this is passed to a label. (Label1) This works great.
I then need to add items to the invoice on a item table so my next stored procedure should take the value of Label1 and update the foreign key quotenumber on the itemtable with the value from label1.
On the aspx page I have a small section for a gridview which shows the current quote with however many items on it using the control
[Code]....
On the ASP page the control for @Quotenumber = Label1 but I get the following error
'Conversion failed when converting the nvarchar value 'Label' to data type int.'

I'm getting this message when going to a web app that accesses my service.
"The content type text/html of the response message does not match the content type of the binding (text/xml; charset=utf-8)..."
The thing is, it happens once in a while even when no changes have been made to the service or the web app. And I can make it go away most of the time by going directly to the .svc?wsdl page in my browser and then coming back to the web app.

Example: I create a custom type in my domain model (say a "Country" class with Id and Text fields)
A "Person" object have a property of the above type.
The Service class return a list of Countries (IEnumerable<Country> GetCountries();)
Now the ViewModel, derive from the "Person" object and have a member "Countries" which is IEnumerable<SelectListItem> Countries (It convert the Country collection from the service to a collection of SelectListItems.
I use the SelectLIst collection to populate my dropdown.
However when I submit the form, validation fail, obviously because the "Country" dropdown give a string value, while a Country object is expected.
So I need to cast this value from a string (using the "id" of the SelectListItem) to a Country object.
Where and how would be the right way to do this? (Another late night with me bing brain dead and probably overlooking the obvious).
So, I've been programming for a number of years. Finding some intricately asinine issues w/ ASP.NET and VB.NET as I learn them. How about this one:
[Code]....
The issue is not Date1
The issue is Date2.
No kidding. I had to String.Format Date1 for some odd reason, even though I'd already validated it. And, yes, I tried to parse and convert Date1 but I kept gettting the typical "Argument 'Date2' cannot be converted to type 'Date'." error. (Did you catch the copy & paste? I didn't edit it from my existing error, but Date2 should be Date1.) Yeah, that's the error I'm getting now with the above ...
"Argument 'Date2' cannot be converted to type 'Date'."
Date2 is a system defined type. Why can't the system convert and/or simply use it's own pre-defined type?

I am using C# & mvc and have an aspx view page where I am trying to use inline code to set the style of a div elemnet:
<div id=MyDiv>
<%= MyDiv.Attributes.Add("class", "MyClassStyle") %>

What is the void it is refering to, is it possible to set the styles like this inline,
In my database when anyone registers - By default the registration time is saved as UTC universal time zone.
But i want to display everything on the website in (GMT-05:00) Eastern Time (US & Canada)
I am using this SQL QUERY to display registration date:
SELECT TOP (5) Username, CustomerID, RegistrationDate = CONVERT(VARCHAR(12),RegistrationDate,107) FROM Customer ORDER BY RegistrationDate DESC
And, i am displaying it like this:
<asp:Label ID="nameLabeldate" runat="server" Text='<%# Eval("RegistrationDate") %>' />
The problem is the output is getting displayed as : 10/20/2010 1:36:01 PM
I know RegistrationDate is datetime stamp that's why i am getting output in this format.
But i want to display RegistrationDate as: Oct 20, 2010 at 1:36pm -> according to (GMT-05:00) Eastern Time (US & Canada) ORDER BY RegistrationDate in Desc (top most will be last registered user)
