I have this code in VS 2003
Private mobjListener As TcpListener
mobjListener = New TcpListener(5000)
mobjListener.Start()
ByVal client As TcpClient
client = mobjListener.AcceptTcpClient
dim strIpAddress as string
strIpAddress = client.Client.RemoteEndPoint.ToString
but the property Client is protected so...
so i want to get the ip address of the client without using mobjListener.acceptSocket
Regards,
Maher

Hi
A few options come to mind:
1) Use .Net 2.0 - the Client property is now public.
2) Use reflection - you can access any property using reflection.
3) Derive from TcpClient - you can then add a public property that exposes the socket.
Take your pick

thanx nicholas for your reply
i want to use it in vs2003
so i want to use either the second or third options:
2) Use reflection - you can access any property using reflection.
3) Derive from TcpClient - you can then add a public property that exposes the socket.
could you please send me samples on how to use them
because i tried to derive from tcpClient but it didn't work
may i made a mistake!

Hi
2) Reflection
PropertyInfo property = client.GetType().GetProperty(
"Client", BindingFlags.Instance | BindingFlags.NonPublic );
MethodInfo method = property.GetGetMethod( true );
Socket socket = ( Socket ) method.Invoke( client, null );
3) Derivation
Sorry - you can't do it this way because the TcpClient is returned from your call to AcceptTcpClient. I didn't read the question properly

Hi
You have to import the System.Reflection namespace.
I don't know VB, so you're on your own there

I did it, and here it is in vb 
Dim myProperty As PropertyInfo = client.GetType().GetProperty("Client", BindingFlags.Instance Or BindingFlags.NonPublic)
Dim method As MethodInfo = myProperty.GetGetMethod(True)
Dim mySocket As Socket = CType(method.Invoke(client, Nothing), Socket)

I am porting an application that I wrote in C# in Visual Studio 2003, (.NET Version 1.1) to the "Compact .NET" framework. When I try to compile the new Windows CE smartdevice project, the compiler displays build errors that state that the "DataGrid", and "ComboBox", are not in the "System.Windows.Forms" namespace. Both the online and included documentation seem to indicate that these controls are included in the compact framework. There is a very similar problem with the OleDb class of the System.Data namespace Other controls like buttons and menus load fine. Are these controls simply not part of the WindowsCE compact framework? Has anybody else run into this type of problem?

Yes, the class comparison tool indicates that the DataGrid class and the ComboBox class are included in Compact .NET.

Hi,
Imaginge that one is dealing with business objects which are exposing their attributes through public properties. One is now able to bind these properties to UI Controls with the build-in .net data binding mechanism. So far so good.
Data validation should be done inside the business objects in two different modes. Every public property on a business object can have a ValidateXXX method which validate just the given value. The second method validates all given data in a context that is meaningfuel for the whole business object instance.
Last but not least all validation messages should be displayed at UI level with an ErrorProvider component. Each control should show the assigned validation error message from the business logic layer.
So far we have some business objects, which are bound to UI controls. We have a collection with validation messages provided by the business object instance.
How to connect the whole thing togheter? The databinding mechanism is the only part that knows which UI Control is bound to which business object property. I miss the part which takes care of settings the validation messages for each control after validation is done.
Shouldn't the databinding mechanism provide a way to transport validation messages and shows them with a ErrorProvider next to the bound control

Hi,
I have faced exactly the same problem and i concluded that my BusinessObject in order to perform proper data-bound functionality has to implement 3 interfaces:
IDataErrorInfo<br />
INotifyPropertyChanged<br />
IEditableObject

As long as you have implemented IDataErrorInfo just set ErrorProvider.Datasource to your object and enjoy the magic.

Hi predragzakisevic,
I'm trying to solve my problem with your solution. I didn't implement IEditableObject, just added IDataErrorInfo. The problem is raised when I try to attach the business object to the error provider as a datasource. It saids that it's invalid because my business object doesn't implement IList.
How did you implemented yor business objects?
Thanks for you answer btw.

class BusinessObject : IDataErrorInfo,INotifyPropertyChanged,IEditableObject ...
{
private Dictionary<string,string> m_Errors = new Dictionary<string,string>();
string IDataErrorInfo.Error
{
get
{
return ((m_Errors.Count > 0) ? "Business object is in an invalid state" : string.Empty);
}
}
string IDataErrorInfo.this[string columnName]
{
get
{
///Fetch from dictionary;
return GetErrorDescription(columnName);
}
}
}

Hi predragzakisevic,
Thank you for your code snippet. Maybe it's not working because I'm running against .net 1.1. Maybe they changed the way the errorprovider works in .net 2.0. If I try to set the errorprovider.datasource which an object that not implement IList I get an exception. As far as I can see your code doesn't implement IList.
I wrote my own DataProvider implementation under .net 1.1 that does the job as well. Great to have your feedback about this topic.
Have a nice day

I am upgrading from Windows 2000 to Windows 2003, using .NET Framework 1.1 and using the CryptoAPI's RSA encryption for encrypting connection string.
I get the error:
"CryptoAPI cryptographic service provider (CSP) for this implmentation could not be acquired"
I checked msdn article http://support.microsoft.com/default.aspx?scid=KB;EN-US;322371[^]. It didn't help.
Also tried to give the account (under which ASP.NET is running) Full Control access to the files containing the keys the WSE will need to retrieve in the following folder:
C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys
Didn't help either.
I am running out of ideas. Some articles suggested to create certificates. I am not sure how I go about doing that. Anybody run into a similar situation before. Any ideas or suggestions?

I found the solution. It works only if both these are true.
1. the user identity under which the program runs has a profile under Documents and Settings.
2.Full Control access to the files containing the keys the WSE will need to retrieve in the following folder:
C:\Documents and Settings\AllUsers\Application Data\Microsoft\Crypto\RSA\MachineKeys

Hi, 
I have a question, I need to set the custom font angle for italic font, how can I do this in GDI?
The default font angle is 15 degrees, but I need to set it to 10, 20, 25 . . .
Please, help!!! I cannot find decision

Im not too sure you can without defining your own font or converting the text to an image and modifying it there
|
|

There are two types of italic fonts. One is a normal font that is tilted, the other is a completely separate font for italics.
For the first type, the angle is specified in the font file. The author of the font has chosen that angle, and there is normally never any reason to use any other angle.
For the second type, the characters just looks tilted. The characters are drawn without tilting, as they already look the way they should, so there is no angle to change.
So there is no support in GDI for changing the angle.

I work with POST SCRIPT fonts, and I saw this functionality in one project, but I cannot understand how did they do that.

Hi,
I'm experimenting with .net 2 and VS2005 support for localization.
Using a sort of Resource Manager wrapper class I give the application the capability of switching in real-time from one language to another, knowing its own default language, ....
The application has a Tool/Settings/Language/... menu that is filled with the available localization languages (the main assembly built-in resources (<something>.resource) and localizations supported by the satellite support assemblies (<something>en-En.resource, <something>it-IT.resource), ...)
So, at startup, I would like the wrapper class to be able to enumerate (at resource, or at resource manager level, not at file system level) the actually available localization satellite assemblies.
Does anyone have an idea about how I can accomplish this little last task?
Of course, should not this possible, I will end in looking directly for the actually available resource files. Anyway I think that this should be an exposed feature of the ResourceManager class.
At the end I would like to post a little article about this work. I searched on CodeProject for Localization Issue and I found something general but nothing similar to what I'm trying to do.
Thanks in advance to everyone,

I am running into a little problem where I can not figure out how to seach for things on the web whether its articles, code, message board answers and find what I am looking for.
I always find aricles, etc. relating to .net ver1.1. when I an developing in ver2.0
this is a problem both on codeproject or if I use google.
this problem is particularly bad when it comes to winforms which where redone in a big way, particularly the data binding. and there seems to be a lack of information about the new systems or at least it is very hard to find.
please post your suggestions.
Thank you
