You need a string if you are binding it to a Text property of the control.
If you do not want to declare a string variable, do it in one line:
myControl.Text = myDate.ToString("MM.dd.yyyy");

Can you explain in details, what problems you are facing and the query you are using ?

If you specify the complete details in your question itself, I am sure you will get lot of replies and you wont waste your time.
Next time please specify complete details in your postings.

ok!
the query i'm using top retrieve the primary keys of all tables in the database is
sql="SELECT name FROM sysobjects WHERE xtype='PK'";
when i execute this query through
DataTable pkey=new DataTable();<br />
sql="SELECT name FROM sysobjects WHERE xtype='PK'";<br />
cmd=new SqlCommand(sql, conn);<br />
reader=cmd.ExecuteReader();<br />
pkey=reader.GetSchemaTable();<br />
reader.Close();<br />
if(pkey!=null)<br />
{<br />
dataGrid2.DataSource=pkey;<br />
}
the output i get is always the same i.e. always only one column name is returned with its attributes and the column name is always 'name'.
i've also tried the following queries:
sql="SELECT name FROM sysobjects WHERE xtype='PK' AND name='name'";
the result is still the same

Hi coolestcoder
i've just got the desired result from the query, by changing me logic from SQLDataReader to SQLDataAdapter.
now i have all the primary keys in the entire DB.
now i want a query which gives me the primary key with respect to its table name. can u please guide me through the query that gives me the desired results.

That was not the reason. The reason was that you were not actually reading the DATA from the data reader, you were reading the schema of the result set. Your SQL Query specified that your result set contained just one column called "name".

U can try this code--
first u feel the dataset by adapter pass datatable to this function-
Private Sub GetPrimaryKeys(table As DataTable)
' Create the array for the columns.
Dim columns() As DataColumn
columns = table.PrimaryKey
' Get the number of elements in the array.
msgbox("Column Count: " & columns.Length.ToString())
Dim i As Integer
For i = 0 To columns.GetUpperBound(0)
msgbox(columns(i).ColumnName & columns(i).DataType.ToString())
Next i
End Sub

i want read mouse data from ps2 port with my application
i know mouse data format that send to ps2 port but i don't know
how read from ps2 port
|
|
|
|
|
The PS2 port is a serial device ( i.e. com port ). If you already have a driver installed reading the mouse you may be able to "hook" in to that or else you can write your driver. You need to know some low level code to read of the com port.

Some thing like this
<br />
@Declare @MyVar1 int <br />
@Declare @MyVar2 int<br />
@Declare @MyVar3 int<br />
<br />
SET @MyVar1 = 1<br />
SET @MyVar2 = 2<br />
<br />
------- Swap @MyVar1 @MyVar2 -------------------<br />
<br />
SET @MyVar3 = @MyVar1<br />
<br />
SET @MyVar1 = @Myvar2<br />
<br />
SET @MyVar2 = @MyVar3<br />

Hello,
I want to update a database. the code i have below gets all the values from a table called roles, and populates a dataset.
I then have a datatable that i want to add some new rows too. I then add this rows to the data table and add the data table to the dataset.
I then want to update the database by calling the dataAdapter update command. The code below as a problem with the update.
I have been told that the insertcommand would be better, but not sure, as i have never used that below. Can anyone give any advice on this.
Many thanks in advance,
Steve
using VB 2005 and SQL Server 2005
<br />
Dim i As Integer<br />
Dim dt As New DataTable()<br />
Dim dr As DataRow<br />
Dim userID As Integer<br />
Dim ds As New DataSet()<br />
Dim da As New SqlDataAdapter()<br />
Dim cmd As New SqlCommand()<br />
Dim cnn As New SqlConnection<br />
Dim cb As New SqlCommandBuilder()<br />
<br />
dt.Columns.Add("UserID")<br />
dt.Columns.Add("GroupID")<br />
Try<br />
cnn.ConnectionString = "server=.; database=serviceMaster; integrated security = true"<br />
cnn.Open()<br />
cmd.Connection = cnn<br />
cb.DataAdapter = da<br />
cmd.CommandType = CommandType.Text<br />
cmd.CommandText = "SELECT * FROM Roles"<br />
<br />
da.SelectCommand = cmd<br />
da.Fill(ds)<br />
dt = ds.Tables(0)<br />
<br />
Catch ex As Exception<br />
<br />
End Try<br />
<br />
userID = 24<br />
Dim chklstIndexes As CheckedListBox.CheckedIndexCollection = Me.chkLstSecurityRoles.CheckedIndices<br />
<br />
For i = 0 To Me.chkLstSecurityRoles.CheckedItems.Count - 1<br />
dr = dt.NewRow()<br />
dr("userID") = userID<br />
dr("GroupID") = chklstIndexes.Item(i)<br />
dt.Rows.Add(dr)<br />
Next<br />
<br />
'Add to the dataset and use the dataAdapter to update the database<br />
Try<br />
ds.Tables.Add(dt)<br />
cb.GetUpdateCommand()<br />
da.Update(ds)<br />
Catch ex As Exception<br />
<br />
End Try<br />

You have a few choices
1) Set your datadapter to write back to the database using update, insert commands configured for your dataAdapter
2) Use SQL commands or storedprocedures to update your data
3) Create an object class with a save method to save data back to the database.
