This should work:

objDv = FilterDataSet(objDs, "SUPERVISOR_NAME LIKE '%se_n%'")

WM.

What about weapons of mass-construction?

Hi All,
I dwnlded the article "Simulating recordset with ADO.NET".I found the coding was meant for SQLserver....I tried to modify to Access DB ..... What shl I do to replace these lines(Its meant for SQLConnection)
' Cursor declared with a SQL-92 syntax (BooksOnLine)
cmd.CommandText = "DECLARE crsr SCROLL CURSOR FOR " & mSelectString
cmd.ExecuteNonQuery()
cmd.CommandText = "OPEN crsr"
cmd.ExecuteNonQuery()

AFAIK, Access/Jet doesn't support Scroll Cursors.

anyone knows the way to open the default email program with an attachment file??
Actually, i have found some code from internet. but,this code not able to attach a file to the email program. the code i found was written below.. thanks for helps..

Function openclient()
'string builder used for concatination
Dim MsgBuilder As New System.Text.StringBuilder
MsgBuilder.Append("mailto:abc@hotmail.com")
MsgBuilder.Append("&subject=this is test subject")
MsgBuilder.Append("&body=this is test body")
MsgBuilder.Append("&Attach=C:\abc.txt")
'Debug.WriteLine(MsgBuilder.ToString)
ExecuteFile(MsgBuilder.ToString)
End Function

Private Function ExecuteFile(ByVal FileName As String) As Boolean
Dim myProcess As New Process
myProcess.StartInfo.FileName = FileName
myProcess.StartInfo.UseShellExecute = True
myProcess.StartInfo.RedirectStandardOutput = False
myProcess.Start()
myProcess.Dispose()
End Function

Your code will generate a commanline like this:

mailto:abc@hotmail.com&subject=this is a test subject...

The & sign before "subject" should be a ? instead. All name value pairs after the first should be prefixed with a &. Like this:

mailto:abc@hotmail.com?subject=This is the subject&body=Message body...

Keep in mind that not all email clients support attachments from the command line. Some even have problems just interpreting the line...

If you have a TAPI compatible modem, then yes, there are lots of ways.

Unfortunatly, you've asked such a generic question, we really can't answer more then that.

First of all, I must say that my english language is very poor ,so excuse my stupid phrases Sigh | :sigh:

The Issue:
Now I had finished my User Control but I want to add a opacity percent property to it, I keep think and think but finally I have nothing , so I am wating for your great help Rose | [Rose]

.

Finally, I really feel that I must say that I think this web site is the best.

Add a Public Property to your control, just like any other. You'll also have to set your controls style that says your painting code support transparency. Then you'll have to update your painting code to support it.

In other words, this is something you should have designed into your control from the start. Adding it as an afterthought is a bit more difficult.

I don't think it's that difficult...
Lets say your old painting code looks like this:

Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
    MyBase.OnPaint(e)

    'Painting starts here...
    e.Graphics.FillEllipse(Brushes.CadetBlue, Me.ClientRectangle)
    'Painting done

End Sub

Then your new paint code can look like this:

Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
    MyBase.OnPaint(e)

    'Graphics of a bitmap to paint on instead of e.Graphics
    Dim bmp As New Bitmap(Me.Width, Me.Height, Imaging.PixelFormat.Format32bppPArgb)
    Dim g As Graphics = Graphics.FromImage(bmp)

    'Painting starts here...
    'Use g instead of e.GRaphics
    g.FillEllipse(Brushes.CadetBlue, Me.ClientRectangle)
    ''Painting done

    'Get rid of bmp graphics
    g.Dispose()

    'Assuming that Opacity is a Single from 0 to 1
    If Me.Opacity = 1 Then
         'Opacity = 100%, so just draw bmp
         e.Graphics.DrawImageUnscaled(bmp, 0, 0)
    Else 'Opacity less than 100%
        'Attributes for the bmp
        Dim attrib As New Imaging.ImageAttributes
        'ColorMatrix for the transparency of the bmp
        Dim colorm As New Imaging.ColorMatrix
        'Set the Opacity of the colormatrix
        colorm.Matrix33 = Opacity
        'Set the colormatrix of the attributes
        attrib.SetColorMatrix(colorm)

        'Draw the bmp on e.Graphics with the right opacity
        e.Graphics.DrawImage(bmp, New Rectangle(0, 0, bmp.Width, bmp.Height), 0, 0, bmp.Width, bmp.Height, GraphicsUnit.Pixel, attrib)

        'Get rid of the attributes
        attrib.Dispose()
    End If

    'Get rid of the bitmap
    bmp.Dispose
End Sub

Hope this helps Cool | :cool:

Doesn't help me, I know this stuff already. You might want to reply to the OP, though.

Hopefully, he doesn't just cut and paste your code and expect it to work! Big Grin | :-D

And, yes, I still say this should have been a consideration when the control was designed and not an after thought.
