Road Map, I would suggest if you can come out with a proper training followed by good demo project. When you plan for training think about all the possible feature that you can use it. Also if this is in line for some upcoming project then you should always keep those requirements in mind while deciding the scope of project.

I'm of the opinion that users should be able to TEMPORARILY have invalid data in a bound control. To enable this, I set Form.AutoValidate to EnableAllowFocusChange so they can leave a control even if there is invalid data. I bind these controls to an object that implements IDataErrorInfo & INotifyPropertyChanged, with property procedures like this:
Private _x As Double
Public Property X() As Double
Set(ByVal value As Double)
If _x <> value Then
If value < 0 OrElse value > 10 Then
_item("X") = "X must be between 0 and 10!" ' For IDataErrorInfo.Item
_item("X") = ""
_x = value
RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs("X"))
Now let's say I enter an "a" into a textbox bound to this property, then I tab out of the textbox into another bound control, edit it, and then leave THAT control, too. This causes the controls to be refreshed with the value of the properties, which means that my invalid "a" gets changed to zero, the value of _x.
My question is: How can I set things up so the invalid "a" gets left in the control until the user decides to re-enter it and change the value?
But this does not work. When I compile to test the program, it tells me that the program is not responding. I assumed that I could use the background like I can assune XPath values to textboxs. Do I need to make the main window refer back to the xml fine even though I made the <window.resources><xmldataprovider ....=""> tags.
I also tried using the above background code for the ListBox and it compiled, but I didn't get any image changes, just white.
Oh another thing that might be important, the image files are .png files. I shouldn't be the problem though, bceause I've seen demo programs that use PNG files. Or maybe the background doesn't like having a PNG.
If anyone knows any alternative ways of doing this, I'm all ears, but I'd like to understand why this doesn't work, though the answer is probably just a "because it doesn't." Thanks for any help.

I need a way to transparently aggregate any .NET class and intercept all calls to that class. I used to be to do this very easily in COM, using COM aggregation and overriding the invoke method. I need to the same thing in .NET. It so I can transparently include code around a method in a given class, the client still invokes the class in same way, unaware they are getting my additional code for free.
Please help me in this issue, I have a website working from a time and i logged on many times to the website administration pages with no problems, after some times i deleted all the cookies from my pc, and cleaned the temp. IE files, so i could not after that logged on to the website admin.
I tried from other pcs if I delete the cookies from there i can not login.
The most important that the login page does not give me an error, it seems i loged on but it does not redirect me to the admin. pages.
I tried to over write the asp net client script files with no hope, some body say that i need to configure the scriptmap of that website!!
anyway I can not globally overwrite the aspnet client libraries for all domains hosted on this server, which is not something I can do on a shared hosting environment.
What is the commands to unregister, fix, register the scriptmap for one application and not for all on IIS?
I use IIS 6 on Win 2003 and asp 1.1
Asp 2.0 installed also but not for this website.
Note: Localy on my pc i have the same configuration but evrything is working perfect!
The prooblem is on the server where they can not solve it!!!
The following question I have is not directly a problem I’m having but rather a solution that I’m looking for.
I have a win32 application written in .NET 2.0, basically a forms over data applications sending data back and forth to a SQL Server 2005 database.
Now, our clients do not want to remote desktop to the server where the application and SQL server resides on, but rather be able to have user have like a client sitting on their local machines accessing the .exe application remotely.
I don’t know if that is possible in the first place, so basically I’m looking for a solution where my users will be able to run the win32 application remotely without having to be on the physical server i.e. remote desktop to it.
Has anybody out here faced a similar challenge before?
I hope I make sense and hope to get your feedback soon.
You have two choices. You can either run the application on each clients machine and the app can connect to the SQL database over TCP/IP, or you can run the application remotely using something like Terminal Services[^] or a Citrix[^] box.

You wouldn't be able "run" the application, however the client app could interact with the server by using .NET Remoting or possibly creating web services on the server to interact with (no you don't necessarily need IIS, you can host the WS within your application).
I download the files about the .net 3.0 WPF and install it on two computers. Both their OS is windows 2003, but one is SP1, another is SP2.
Now I found that the WPF's project could work well in SP!, not work in SP2. I don't know whether this is the reason.
Does anybody meet this problem too? Please give me a advice, thanks very much.
