There may be an easier answer than just digging up one for this. What's the final goal you're trying to reach?

Hi leeland,

the final goal to achieve is a complete component and control iteration of a form to disable /enable them and make them in-/visible if demanded. But this in a dynamic way, cause i never can tell in advance what will be on the Form.

tnx Leeland,

i've found the solution: i needed to use reflection

                <br />
strFormName = param_Form.Name<br />
<br />
                Dim param_Form_type As Type = param_Form.GetType()<br />
                Dim compFields As FieldInfo() = param_Form_type.GetFields(BindingFlags.Instance Or BindingFlags.NonPublic)<br />
                For Each fiField As FieldInfo In compFields<br />
                    Dim strCtrl(1) As String<br />
                    strCtrl = ReturnCompName(fiField, param_Form)<br />
                    For Each dr As DataRow In myrs.Rows<br />
                        If strCtrl(0) = dr("SecAuthCtrl_Name") And fiField.FieldType.FullName = dr("SecAuthCtrl_Type") Then<br />
                            Select Case fiField.FieldType.FullName.ToLower<br />
                                Case "System.Windows.Forms.ToolBarButton".ToLower<br />
                                    Dim cmp As ToolBarButton = DirectCast(fiField.GetValue(param_Form), ToolBarButton)<br />
                                    cmp.Enabled = dr("SecAuthorized_Enabled")<br />
                                    cmp.Visible = dr("SecAuthorized_Visible")<br />
                                Case "System.Windows.Forms.MenuItem".ToLower<br />
                                    Dim cmp As MenuItem = DirectCast(fiField.GetValue(param_Form), MenuItem)<br />
                                    cmp.Enabled = dr("SecAuthorized_Enabled")<br />
                                    cmp.Visible = dr("SecAuthorized_Visible")<br />
                                Case Else<br />
                            End Select<br />
                        End If<br />
                    Next<br />
                Next

this works now,

tnx for your effort

Hi,
In my client application,it requires to access a file in the remote server station within LAN, which requires authentication(User name and password)in VB. Provide me any sample code that has code to authenticate remote PC file access.I am not using ASP or VB.NET.

I had this same problem once, and I never really figured out a good way to do it. I ended up kinda cheating and just setting the selection highlight to the same color that the row was already. You can set the default row highlight and the alternating row highlight if you use different colors for alternating rows. Here's the code I used:

MyGridView.DefaultCellStyle.SelectionBackColor = Color.White<br />
MyGridView.DefaultCellStyle.SelectionForeColor = Color.Black<br />
MyGridView.AlternatingRowsDefaultCellStyle.SelectionBackColor = My.Settings.ContrastBackColor<br />
MyGridView.AlternatingRowsDefaultCellStyle.SelectionForeColor = My.Settings.ContrastFontColor

Let me know if you find a nicer way!

I am trying to use the getbitmapbits funtion of the mediadet in vb.net,is that possible,My code is given below plz find errors,as it does not respond when getitmapbits function is called.

CODE

Dim width As Integer = 480
Dim heigh As Integer = 640
'Dim mediatype1 As _AMMediaType
' Dim vih As videoinfoheader = mediatype1.
' get buffer size
Dim abuffer As Byte = 0
Dim buffer As IntPtr = IntPtr.Zero
Dim md As MediaDet
md.Filename() = txtFName.Text
md.CurrentStream() = 0

Dim bufferSize1 As Integer = 0
md.GetBitmapBits(0, bufferSize1, abuffer, width, Height)
MessageBox.Show("buffersize got and is = " & bufferSize1)
Dim bmpinfoheaderSize As Integer = 40
Dim bufferSize As Integer = (((width * Height) * 24) / 8) + _ bmpinfoheaderSize

' allocate buffer, then get bitmap bits
buffer = Marshal.AllocHGlobal(bufferSize)
md.GetBitmapBits(0, bufferSize, abuffer, width, Height)

' marshal to struct and then dealloc
'dim header as BitmapInfoHeader = system.Runtime.InteropServices._ Marshal.PtrToStructure(buffer,typeof(BitmapInfoHeader))
Dim p As New Bitmap(width, Height, width * 3,_ Imaging.PixelFormat.Format24bppRgb, New IntPtr(CInt(abuffer) + 40))
PBox.Image() = p

System.Runtime.InteropServices.Marshal.FreeHGlobal(buffer)
