which line causes your app to hang?

way too few details...improve your question and specify what you have tried so far and what exactly you are trying to do!

you´re welcome ;)

plz post your ServiceContract-Interface, ServiceImplementation-Class and web.config.

smells like homework...what have you tried so far?

you´re on the right way.
Define a class "User" with public properties "Username", "Password", "Gender".
modify the "List" stored in variable listPost in your above example to hold instances of this class.
for each record in the resulting DataSet, instantiate a new Instance of "User" class, setting the Properties according to the corresponding Cell of your DataRow.
Add these new instances to the List (which result in setting the ItemsSource-Property of the ListView.
Modify the Bindings in your DataTemplate to match the "User"-classes propertynames (case sensitive).
Add Eyecandy to your DataTemplate so it looks like the example you posted in the pic

yeah, just noticed the BindingFlag :)

you try to invoke a method on "Nothing (null in C#)"..no wonder this throws a NullReferenceException...

btw: really bad variable naming. you should always use names that actually make sense...

what line is causing the Exception? could only be trying to get the enumerator for "Model" or accessing the "Name"-Property of a null reference in "genre"

I'll see if i can manage to improve the solution, providing a more detailed sample on how to accomplish this. Nevertheless i recommend to bind the TreeView's SelectedItem-Property to a appropriate ViewModel-Property, as this would drastically reduce the coding needed compared to the other approach.

btw: your xaml-snippet is missing a binding to the IsSelected property of your dataitem...you provide a style for the TreeView's ItemContainerStyle but don't have any setters in it!

already got a look at
http://msdn.microsoft.com/en-us/library/system.windows.controls.virtualizingstackpanel.aspx
?

btw: what technology? WinForms/WPF?

it depends on the implementation of sampledbDSTableAdapters.productTableAdapter.Insert - method

if it is generated, then it most likely will make use of SqlParameters to "inject" your provided values into the Insert-SqlStatement - and therfore should prevent most of the common SqlInjection scenarios.

it's nice of you keeping the detail of your problem as low as possible, but no one will ever possibly can give you a direction to look at if you don't supply more information (e.g. your configuration, exception-details like a stacktrace, etc.)

from those information-bits that you provided, it seemed as if your configuration-file is sort of messed up...

Ok, that sure seems weird. But the complete Drag&Drop behavior is a chapter of it's own since the beginning...WPF, sadly, does nothing to make this event-hazzle a bit more programmer friendlier (at least not OOTB).
I would check if the DragDropEffect your are setting is supported by the Lync-Drag operation (e.g. by examining the AllowedEffects-property of the DragEventArgs).

Also try to hookup to the GiveFeedback-event.

Sorry i can't help more on this issue.

Hey!
I provided a second solution...hope it clarifies things up! ;)

Give me some time and i'll see if can wire up a sample for you. I'm a little bit busy right now...;)

sorry, but this is such a basic concept...i think you should read about classes (types) and instances. once you have done that, you will be able to solve your issue by yourself! (hint: you should pass an existing instance of Form1 to a new instance of Form2 using either a constructor or a property...)
if i misunderstood your question, please dont hesitate refining your question to a more specific problem.
http://en.wikipedia.org/wiki/Class_(computer_programming)

as you are facing case 2.), i asume that you have a web.config at web-SITE level and one on application-level. check, if there are add-Elements with the same name in it

strange behavior...sure, this would be a workaround for the lack of lambda-support. but how do you pass in the variables to "Lambda1" when the "Albert"-string is not a constant without introducing new fields (which would mimic the Closure in a minimalistic way)?

i´m suprised that my original solution does not work for you, as i did not encounter any problems with VS2010 / VB.NET 10.0 (even on .NET 2.0)

you´re welcome! glad could´ve helped you!

You don´t have to define the Action<t1,> delegate, if you are using .NET 3.5.
And even if you had to, i could not answer this question, as it depends on your project´s structure and architecture...
Just make sure that it can bee "seen" by the calling site ;)
mayby try out the VS2008 (VB.NET 9.0) fallback that i provided, as the error message you are facing implies that you are using VS2008.

see my improved solution! are you using VS2008 / .NET 2.0 ?

1. Sub Main() is just a sample that demonstrates the usage of this pattern.
2. the "location" of "ExecuteWithinTransaction" depends on your architecture...maybe it can be integrated in your SqlDatabase-class for general purpose.
3. The additional parameters would do the trick, even though this pattern can be more generalized in order to get less verbose method-signatures.

if it helped, please rate and mark the question as solved!

everytime you build an sql-command using string concatination you open up your application for possible sql-injection. It seems to me that you are using a custom "framework" for building your queries and i dont know how the method "AddInParameter" is implemented in detail - i assume for know that it uses standard SQL-Parameter to prevent SQL-Injection.
you should always build your commands like:
var commandString = "Insert into XXX (ColumnA, COlumnB) VALUES (@ColumnA, @ColumnB)";
var cmd = new SqlCommand(commandString, connection);
cmd.Parameters.AddWithValue ("@ColumnA", 123); //or a similar approach to "replace" those parameters.

in this way,, the SQLServer can "precompile" the statement and "inject" the parametervalues by itself and check, if the overall command gets broken (by ensuring the dataType of the parameter, etc)

when you build up your statement like:
var cmd = new SqlCommand("INSERT INTO XXX (ColumnA) VALUES ('" + columnA +"' +);

columnA may be defined as "A'); DROP TABLE XXX; --", resulting in a command like:
INSERT INTO XXX (ColumnA) VALUES ('A'); DROP TABLE XXX; --');

even if chances are low that this will actually be exploited(e.g. because the parameter you are concatinating is not provided by direct user input or SqlServer does detecting thos malicious queries), at least the possibility remains, what almost always is a bad code smell.

In your solution, this happens with the "Gender" Parameter in "createNewAccID" and "accID " in "insertIntoMandatorySteps"

Edit1: Codesamples are C#-syntax

what do you mean with "apply transaction when calling the functions"? can you provide more details about your purpose?
BTW: are you aware of the possible sql-injection in your solution?

Your welcome, see my provided solution as a possible start to solving your problem

i think nobody really understands what you are trying do achieve nor what your problem is...try to provide more details about your intensions and what the code should actual do!

your sample is missing definition of
field "m_transform" and method "GetMatrix"

where do you get what type of exception?
nevertheless, if you have mapping code (Migrate32BitsStructTo64BitsStruct), why do you stick to a solution using reflection rather than copying those three values by hand, like:

struct32bits source;
struct64bits target;
target.lVersionNumber = Convert.ToInt64(source.lVersionNumber);
etc...

(i think, but am not sure, that is what SA suggested?!)

what should the timer do? just keep track of the elapsed time?

DllImport (System.Runtime.InteropServices.DllImportAttribute) is defined in mscorlib.dll. make sure you add a using directive to its namespace:

using System.Runtime.InteropService;
refer to http://msdn.microsoft.com/en-US/library/system.runtime.interopservices.dllimportattribute.aspx

and remember: MSDN is your friend :)

the output gives

[DllImport("user32.dll", EntryPoint="SendMessageA")]
private static extern int SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);

please tell us more about your intensions to do this!
1.) do you want an array of instances of a generic type?
2.) or a generic List which elements are Arrays of a type?

you need to execute those commands under full administrative privileges. make sure you start your command line "as administrator". does this solve the issue?

what technology are you using? ASP.NET? WPF? WinForms?
