how to save pic in your database
|
|
|
|
|
Here ya go. FYI, it's more efficient to save a pic in a file directory rather then a database.
Dim bufferLen As Integer
Dim fs As System.IO.FileStream
Dim br As System.IO.BinaryReader
Dim buffer() As Byte
bufferLen = 10000000
fs = New System.IO.FileStream(fileName, FileMode.Open, FileAccess.Read)
br = New System.IO.BinaryReader(fs)
buffer = br.ReadBytes(bufferLen)
br.Close()
fs.Close()
Dim sConn As New String(strConnection)
Dim Con As New SqlConnection(sConn)
Dim sqlcmd As SqlCommand
sqlcmd = New SqlCommand("INSERT INTO Picture (Picture) VALUES (@Picture)", Con)
Dim dataParm1 As SqlParameter
dataParm1 = sqlcmd.Parameters.Add("@Picture", System.Data.SqlDbType.Image, buffer.Length)
dataParm1.Value = buffer
Con.Open
sqlcmd.ExecuteNonQuery()
Con.Close()

Hi,
I am binding the database column with dropdownlist box.It is working fine.
But i have to set particular value as my first value in the dropdownlist box.
for example, the coulmn values are
Windows 2003
Unix
Solaris
Linux
Windows 2000
Windows XP.
I want to show Linux as my first value in the dropdownlist box, then other values.
Linuxt may be 5 th record or 24 th record or anywhere in the table.
I have used simple query now. "SELECT CategoryName From Category".
Can any one help me to write a query.
Thanks & Appriciate You.

Since you require a sort order and that sort order is not the lexical order of the text, you can add a column to the table called, .. Sort_Order. Load that column with unique numeric values and then your query becomes "Select CategoryName from Category order by Sort_Order".

Perhaps another way would be to not bind a datatable to the control, but to loop manually around the datatable adding the data items to the control. Put an IF clause in to look out for the item that you want and insert this into the first position of the control.

I have a recordset and want to push this one into a database. Is there any way to do it without a recordset loop ?

You can look into the BCP command in SQL Server. If you are using VB I think you can do a rs.Save to save it to a text file. It has been a while since I used VB so can't remember if you can set the delimited for the file or not. If you are using .Net, not sure. I do know you can save it to an xml file using the dataset object. I haven't notice the capability to save to disc in any other format though, but it might be there.
Also, triggers don't fire when you use BCP.

Hi,

JOIN == INNER JOIN. INNER JOIN is implied when using JOIN. No performance difference.

I thought similar but was just wondering about the performance. Thanks anyways!

Could you explain your questions in a different way? Do you want to transfer data between an SQL database(SQL Server or MySQL) and an Access database?

So i want to transfer data between an SQL database(SQL Server 2000) to an Access database.
If you knew any thing about this problem please tell me.

Well, you can create DTS package in SQL Server to transfer data, and then run the package from your application. Do you get it?

What information are you trying to store/retrieve? From your description, it sounds like you may be able to handle what you want in code.
