i want to capture video using pocket pc (WM5) , encode it then store it and transmit it using UDP packets
@ the laptop side the packets'll be recieved , decode and display them one at time
which means streaming technique in delivering the video ;
split the video into parts , transmit these parts in succession (using UDP packets) and enable the receiver to decode and playback the video as these parts are received without having to wait for the entire video to be delivered (on pocket pc side: capturing video - encoding - storing - sending ) so the streaming in sending only :
1- partition the compressed video into UDP packets.
2-start delivery of these packets.
3-begin decoding and playback at the receiver while is still being delivered.

.i've problem in disply the video on the desktop as soon as the first packet is recieved

note
i use VB.NET or C# no problem
plz i need ur help
thanks alot

Well, that's a bit vague. What kind of problem?

Questions about System.IndexOutOfRangeException: There is no row at position 0. Error

Hi All;
I'm running some query's against SQL 2005 server. When I run the query's in SQL server they return Null values because there is no data yet.
In my VB code the same query's generate the System.IndexOutOfRangeException: There is no row at position 0. error. I have not been able to come up with a way deal with this.
It seems to happen before this fill line happens
datafromDS(0) = Me.DataSet11.Tables("tblMyTable").Rows(0).Item(0)

Any suggestions on how to handle this. There are times when new records have been added that have Null data in them.

TIA
Rafone

First make sure you have a table, then check the rows

If not me.dataset11.tables.contains("tblMyTable") Then
    'blow up no table -- or however you want to handle it
    Exit Sub
ElseIf me.dataset11.tables("tblMyTable").rows.count = 0 Then
    'blow up no rows -- or however you want to handle it
    Exit Sub
End If

Also check the value of Item(0) against DBNull.Value and the target type.

It's the exact same thing. Instead of using .Net's Process class, use the ShellExecute API, or the Shell function.

Userdefined control containing form ctrls: How to set the properties of the form ctrls in the designer?

mp00017-Aug-08 1:19

Hi group,

we have a userdefined control (called e.g. LabelAndMore) which contains a Label and other controls. When I apply this userdefined ctrl LabelAndMore in eg. a form I need to set the properties of the label.

Of course, we could add properties like Label_Text and Label_AutoSize in LabelAndMore. For a label this would be ok. However, if a more complex control with more relevant properties is needed instead of a label, all its properties would have to be added in LabelAndMore just to mirror the already existing properties of the complex control to LabelAndMore.

Thus we had the idea to add the property

Public Property Label() As Label
Get
Return Me.Label1
End Get
Set(ByVal value As Label)
Me.Label1 = value
End Set
End Property

in LabelAndMore. At the first glance this approach looks quite fine. When I add a LabelAndMore to e.g. a form and look at the property list of the inserted instance of LabelAndMore, the new property Label shows. It has a plus symbol in front of it. Expanding it one gets all the properties of the label. But unfortunately the designer does not create code in Form1.Designer.vb for the changed properties of the Label within LabelAndMore.

What do we have to do so that changes of the properties of Label in LabelAndMore are added to the code created by the designer?

I guess it is possible because a split container does it. It consists two panels called Panel1 and Panel2 and the changes of their properties are added in the code created by the designer.

Me.SplitContainer1.Panel2.Enabled = False

Kind regards and thanks in advance.

Finilly I have found a solution which seems to work. I've had a look into the source code of the .net framework for the SplitContainer mentioned above. It shows

/// <include file="doc\SplitContainer.uex" path="docs/doc[@for="SplitContainer.Panel1"]/*" />
/// <devdoc>
/// The Left or Top panel in the SplitContainer.
/// </devdoc>
[
SRCategory(SR.CatAppearance),
SRDescription(SR.SplitContainerPanel1Descr),
Localizable(false),
DesignerSerializationVisibility(DesignerSerializationVisibility.Content)
]
public SplitterPanel Panel1 {
    get {
        return this.panel1;
    }
}

If I use this in my case the problem is solved:

< _
System.ComponentModel.Localizable(False), _
System.ComponentModel.DesignerSerializationVisibility( _
        System.ComponentModel.DesignerSerializationVisibility.Content) _
> _
Public ReadOnly Property Label() As Label
    Get
        Return Me.Label1
    End Get
End Property

Some infos from the VS 2008 docu:

' HINT from VS docu for "SRCategory"
' (no entry available)

' HINT from VS2008 docu for "SRDescriptionAttribute Class"
' Provides an attribute for use in upgrading Visual Basic 6.0 applications to Visual Basic 2008.

' HINT from VS2008 docu for "DesignerSerializationVisibilityAttribute Class"
' When a serializer persists the persistable state of a design mode document, it often adds
' code to the initialization method of components to persist values of properties that have
' been set at design time. This happens by default for most basic types, if no attribute has
' been set to direct other behavior.
' With the DesignerSerializationVisibilityAttribute, you can indicate whether the value for a
' property is Visible, and should be persisted in initialization code, Hidden, and should not
' be persisted in initialization code, or consists of Content, which should have initialization
' code generated for each public, not hidden property of the object assigned to the property.

' HINT from VS2008 docu for "LocalizableAttribute class":
' When code is generated for a component, members that are marked with the LocalizableAttribute
' set to true have their property values saved in resource files. You can localize these resource
' files without modifying the code.
' By default, members that have no localizable attribute or are marked with the LocalizableAttribute
' set to false will have their property values persisted to code, if the data type allows.

I don't know anything about NetFlow, but if they are just regular ol' packets WinPcap[^] can do that. Here's a good .Net wrapper for WinPcap: SharpPcap - A packet capture framework for .NET[^].
