I'm sorry, but you seem to be under the misapprehension that we do your work for you. That's not what these forums are for - they are for you to tell us what you've tried, and then for us to give you some pointers to help out. That's it.

Can any one give me idea how i can validate a texbox. I mean user should enter some thing in the textbox(Like Required field validation in asp.net). Please give me a simple example.

Well - there are many ways to perform validation in WPF. Here's an example of a validation rule that ensures that your input matches a particular format. The first part is a C# class:
public MatchRule : ValidationRule
{
public string MatchText { get; set; }
public override ValidationResult Validate(object value,
CultureInfo info)
{
if ((string)value == MatchText)
return new ValidationResult(true, null);
return new ValidationResult(false, "This is not a match");
}
} and in the XAML:
<TextBox>
<TextBox.Text>
<Binding.ValidationRules>
<local:MatchRule MatchText="Hello" />
</Binding.ValidationRules>
</TextBox.Text>
</TextBox>

I ‘m working on audio conferencing in - WCF, WPF and Visual Studio 2008 using C#. I capture the sound from microphone using Windows API. Then I continuously capture the sound from microphone and send the Audio stream (byte[]) to the server and broadcast from there. Its working fine and I also get the response from the server as well. Then I play the Audio Stream(byte[]) coming from the server.
I used this article in codeproject website to record and play audio stream.
http://www.codeproject.com/KB/audio-video/cswavrec.aspx
But when the incoming audio stream is playing, an unrecognizable sound is coming. This may be due to the difference between data consuming and receiving rates.
I also used directsound to record and playing sound but the same problem arise.
So please suggest me how to solve this problem( Better DierctSound suggestion – Streaming Buffer) .
This code is fire when audio stream is received from the server.
private void playAudio()
{
objAudioConferencingPlayer.StartAudioPlayer(IncommingAudioStream);
}
public void StartAudioPlayer(byte[] AudioStream)
{
if (!IsPlayerRunning)
{
StopPlaying();
m_Player = new WaveOutPlayer(-1, fmt, 16384, 3, new
BufferFillEventHandler(Filler));
IsPlayerRunning = true;
}
m_Fifo.Write(AudioStream, 0, AudioStream.Length);
}
private void Filler(IntPtr data, int size)
{
if (m_PlayBuffer == null || m_PlayBuffer.Length < size)
m_PlayBuffer = new byte[size];
if (m_Fifo.Length >= size)
m_Fifo.Read(m_PlayBuffer, 0, size);
else
for (int i = 0; i < m_PlayBuffer.Length; i++)
m_PlayBuffer[i] = 0;
System.Runtime.InteropServices.Marshal.Copy(m_PlayBuffer, 0, data, size);
}
Thanks in Advance.

Hello,
I am trying to build an UI with different "pages" (xaml as usercontrols) which are showed when some
buttons in the principal shell are pushed.
The principal shell creates an object during inialization whose properties I would like to change
using the usercontrol UI´s.
Whe doing this with Windows Forms it was enough to me to pass the main object as reference to other forms class. Now I am trying to do this in WPF but for some reason the main object dissapears.
Which could be the problem?
Thanks

Can any one Help
I mean, I want to create a application that has a toolbox and drag the controls from toolbox and drop in the workspace. Once we drop the controls in workspace, the properties related to that particular control should be displayed in property Panel.Once we change the properties it should affect the workspace controls.(This Application like Visual studio toolbox and property box)
can any one give some Idea.

Why did you delete your post below? You should have clarified that post rather than leaving my answer to it dangling.
Anyway - you're obviously going to have to write a property grid control and populate it with the properties using Reflection. That's a fair bit of work there.

I'm not sure what you're asking. What do you need help with?

I have a couple questions for WPF that I hope have simple answers:
Suppose I want to make my interface modular and abstract, so that I don't need to group everything into a single xaml file. What is the simplest and most efficient way to dynamically swap out pieces of a xaml interface?
In WinForms this could be done simply by using panels, and changing the child control(s) of the panel. Is there a similar idea in WPF?
And relatedly, what's the best way to define xaml fragments that aren't entire windows themselves. User controls? Pages?
And finally (bonus, unrelated question): is WPF layout strictly grid/hierarchically-based? If I want a fragment such as the above to appear floating over the other elements in a window/grid, can i do that without creating a new window?
In your debt,
Logan

The architecture you want to consider is the Composite Application Guidance[^]. This architecture is designed to apply the "hot swapping" because it uses IoC. Please have a look at this[^] link for more details.

Well - I'm partial to User controls myself.

Oh yes - WPF is full of funky 3D goodness that allows you to move elements through 3D space.

Thanks I will take a(nother) look at that. I had skimmed it earlier, but I thought that since it required an actual DLL that it was something way more than what I was looking for.

I hate to say this, but it drops in quite a few. You get the Unity Dll as well.
