How to assign null value to a column of "DateTime" type generated by Typed DataSet
Hi, is there a neat way to let Typed DataSet return null for a datetime column. By default as long as a column's value bound from Datasebase is NULL, it will return DbNull, which will in turn causes expection as client refer it, and we cannot assign a default value, null, to it.
Thanks a lot

Go to the typed dataset designer (.xsd) and set the value of datatime field's "NullValue" property to Null instead of Throw an exception. In this case...Error:"The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value."
I still don't know what is happening with my application. I used before in another page the formview control and I didn't have the out of range Date error. It was normally. But now, I'm doing everything manually and I don't know why, but I'm with this problem. I need to safe this problem today... Here go my code!
The error occurs here: (It's the Sub that Insert data inside of the database(SQLServer)Protected Sub Gravar_Click(ByVal sender As Object, ByVal e As System.EventArgs)

The problem is usually that the .NET DateTime object does not have the same range as the SQL one. So if you h....ALLCOL("%COLUMN%", " ", ", ", ", ")
Do you know anyway for me to exclude a subset of columns returned by this
function. We have two columns (rec_user and rec_datetime) which are in all
of our tables, but when generating triggers I want automatically generate a
script which does not include those two columns but does include all other
columns in that table.
I should add that I am using PD 126.96.36.1990.

I want to change the button on the control to be a specific colour i.e. other than the default grey. However, I can't find an attribute for this. The background attribute changes the input box area colour. Is there a way to change the colour of the button?

hi , i have a problem
i have an textarea that i want to convert to DateTime format (dd/MM/yyyy) .
the data in the textarea is (dd/MM/yyyy for example 21/12/2005).
i need it to add this data in sql server , in smalldatetime formation colum .
Wouldn't you just use:
DateTime dt1 = DateTime.Parse( stringToParse, formatProvider, styles)
This doesn't quite seem like a SQL Server question ... but in ASP.NET you can convert a string to a date using the DateTime.Parse(string) method.
Then you could use this as the value of a parameter to a stored procedure with t..."Time Server Type" vs. "Timesync Type"
We have two time sources within our network: a Reference server
and a Primary server . . . both are pointing to External Time Source
servers and to each other.
I was looking at their settings and confess I'm confused about
the difference between two settings:
- Default Time Server Type
- Timesync Type
Both settings offer the standard selection of Single, Secondary,
Primary, and Reference.
I've matched both settings to their server (either Primary or Reference)
but I don't know what the difference represents.
I know .NET does not produce valid code - but it is a requirement where I work to make all pages valid. I've read the Liquid Internet article for derving from the base control classes but I'm on a tight deadline right now so...
I can get my pages XHTML 1.0 transitional which is good enough for now except for ONE small tidbit, where .NET writes out the __doPostBack JS method like this
is there any simple way to get it to add

Trying to understand this logic:
We can choose: "Mricrosoft SQL Server" or "Mricrosoft SQL Server Dababase File" as our data source.
I understand that if we choose: "Mricrosoft SQL Server", the database is located in server, such as: c:\program files\Microsoft SQL Server\MSSQL1\Data\Northwind.mdf
But if we choose: "Mricrosoft SQL Server Dababase File", what will it happen? does that mean it will create a copy of a database (say Northwind.mdf) to my current web application foler, say in: App_Data foder?

The data is then bound to a repeater control and displayed.
