No problem.
BTW: are you sure you want an e-mail address as an account name, visible to everyone?
you could change it in your settings page...

Hello. I'm a relative newbie to NET Framework programming and I have a problem I can't seem to get my head around. I have an application that I need to read in customer supplied string values that are paths to executable programs that open CAD drawings in the specified external program. I have read about the Configuration Manager classes and XML Document object and I'm not sure what the best method would be. I considered using the OpenMappedExeConfiguration() method to read in the values supplied by the customer but I'm not to versed on how the merging of configuration hiearchy occurs when the Configuration object is created. I want to keep the scope of the config file at the application level.
Alternatively, I am considering creating an external XML config file and using the XMLDocument class to read in these path string values and set the executable paths that way. This seems like a more direct way to control application scope for the configuration file and I believe the default values for the path strings could be set in the ApplicationSettingsBase Class under the My Namespace in the Settings.Designer file. Is that a correct assumption?
Unfortunately I'm not real savvy on creating XML documents and the related nodes. Any advice on the best methods for implementing this or information on resources I would GREATLY appreciate!

If the file is supplied by the customer then I doubt very much it would be in a format usable by ConfigurationManger. Your best bet would be to use XmlDcoument, or better yet XDocument if using 3.5 or higher.

Thanks for the input Mark. Yes, that's what I thought - the best way would be to read in config values as they would have to be serialized.
I had another thought - I could create a custom configuration class to read the config file at the configuration file path and create a custom configuration section that would allow the user with the proper access rights to make changes to the elements in the section. That way I believe the serialization is handled by the configuration class. Does that sound like I'm on the right track or do I still have a bit of reading and experimenting to do?

Stop even thinking about using the config file. App.config and web.config files have elements that should never be exposed to end users. For the application, as you have described it, it is not the best tool to use. Use an external file with a defined schema that you can serilaize of read with XmlDocument.

Dears,
Iam new to vb.net,please help me to pass parameter to for my VB.net project,
I want to pass @Ridfrom to SP:usp_Procedure and return value to @PidTo .
The below mentioned is my codings.can u susggest a way to solve the error
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
Dim combo As String
Dim SQLEV As SqlClient.SqlConnection = New SqlClient.SqlConnection
SQLEV.ConnectionString = "Persist Security Info=False;Integrated Security=SSPI;database=db_chart;server=nrppc-mis1\sqlexpress"
combo = ComboBox1.SelectedValue.ToString
Dim command As New SqlCommand("usp_Procedure", SQLEV)
Dim adapter As New SqlDataAdapter(command)
command.CommandType = CommandType.StoredProcedure
With command.Parameters
.Add(New SqlParameter("@Ridfrom", SqlDbType.NVarChar))
.Add(New SqlParameter("@PidTo", SqlDbType.Money)).Direction = ParameterDirection.Output
.Add(New SqlParameter("Returnvalue", SqlDbType.Int)).Direction = ParameterDirection.ReturnValue
End With
End Sub
this is my stored procedure
eg:If i pass @RidFrom=1 im getting Output value @pidTo=3
ALTER PROCEDURE usp_Procedure
@Ridfrom nVarChar(50),
@PidTo nVarchar(20) output
AS
SELECT @PidTo = ProcDetails.Procedure_ID
FROM ReportMaster INNER JOIN
ProcDetails ON ReportMaster.Procedure_ID = ProcDetails.Procedure_ID
WHERE ReportMaster.Report_ID = @Ridfrom
RETURN

What error? You don't mention getting any errors.
@PidTo does not need to be an output parameter, the value of ProcDetails.Procedure_ID will be returned from the select statement.

Dear Mark,
thank you for your suggestion.
I tried in that way i was successful to ruen value from the SP.
but now the problem is im not able to pass and retrieve value to and from this SP.
@Ridfrom and return value is not changing.
please help me
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
Dim SQLEV As SqlClient.SqlConnection = New SqlClient.SqlConnection
SQLEV.ConnectionString = "Persist Security Info=False;Integrated Security=SSPI;database=db_chart;server=nrppc-mis1\sqlexpress"
Dim combo As String
combo = ComboBox1.SelectedValue.ToString
MsgBox(combo)
Dim command As New SqlCommand("usp_Procedure", SQLEV)
Dim adapter As New SqlDataAdapter(command)
command.CommandType = CommandType.StoredProcedure
'command.Parameters("@Ridfrom").Value = combo
With command.Parameters
.Add(New SqlParameter("@Ridfrom", SqlDbType.NVarChar))
.Add(New SqlParameter("Returnvalue", SqlDbType.Int)).Direction = ParameterDirection.ReturnValue
MsgBox(command.Parameters("@Ridfrom").Value)
MsgBox(command.Parameters("Returnvalue").Value)
End With

Are you expecting the values to be displayed in the messageboxes? Of course nothing has changed, you have not caused the command to execute yet. 
Please read a book or article on ADO.NET before trying to work with it, you don't seeme to understand how it fuctions.

I installed some .net application on my machine ( lets say this is some exe ).
I double click on the file - and now there are two options
A. the exe file is ran once before this double click - and that mean that the IL code is compiled and the native code is exists => in this case the exe.
B. the exe file is running for the first time - and the IL is not compiled yet by the JIT compiler ==> that mean that now the IL code will compile and the native code will be stored at some place.
My question are 
1. How the .net framework know if the code was compiled already ?
Is there some flag or some sign that can tell if the native code compiled already ?
2. Where the native code will be stored ?
Thanks for the help.

The native code is not kept around beyond the execution of a process. Whenever the EXE starts it will gradually JIT-compile whatever classes/methods need executing.

Unless you use ngen.exe, your executable will be compiled everytime you run it.

Hi,
I have a client server architecture, may have 1000+ clients (windows application/winforms) communicate with the hosted server to process some information!
There may have 3 to 4 methods/function to be processed on the server.
Both client and server can be developed in any of the .net technology like we have .net remoting, asp.net web service or WCF Service!
If you can advice which one will be feasible of this requirement.
Like in performance point + load on the server for the request/response time. I am not much worried about the security (its intranet/vpn).
Thanks in advance!
Waiting for the response!

You can use WCF for the services which the clients will be consuming. It will allow you to communicate with any client (not just .Net) through a lot of means like http/namepipes/tcp etc.
Plus, it being a newer technology, you don't have to worry about an upgrade at least for few years.

There are two aspects that you need to consider while you choosing among
.NET Remoting Service, Web Service and WCF Service.
1. Portability
-> If you are using .NET Remoting Service then both client and server should be in same
technology (e.g. .NET in this case)
-> While if you consider Web Service or WCF service you can also access it from linux machine
or any other OS based machine (as client).
2. From request/response time point of view or performance point of view .NET remoting service
is always best compared to web service and wcf service.

This is the latest so should be an easy pick.
However, WCF service provides many different types of bindings and picking the best binding for your application will not be easy.

Hey guys,
I wonder whether anybody can help me out in this problem. I use wcf to get data. After I got the data, I cache them using Enterprise library Cache block. I am trying to incorporate the sqlDependency cache- notification model to invalid my cache.
Anyone have better idea to solve this problem or setup the SqlDependency expiration across wcf end points?
Thanks,
Sen

I have a piece of hardware with some buttons which when pressed will send an events via a USB interface to an application I have written(let's call it APP1).
I have a 2nd application (let's call it APP2) that reacts to certain keystrokes (for example when it sees a Key Press event for SPACE BAR it will pop-up a dialog). I have no control over the code in this application.
I need to make it so when APP1 sees a button is pressed on the hardware it will send a keystroke to APP2 (or to all windows).
Some constraints:
- I cannot change the hardware to simply send the SPACE BAR, I only have control over APP1.
- There may exist another version of APP2 that will react to a different button such as ENTER key (or any key sequence for that matter) so I would like to have APP1 be configurable in the event it sends to other windows/applications and is in no way dependent on the name of APP2 as I may see many versions of APP2.
What is the best way to handle this? Sendkeys?
What information do I need to know about APP2 from within APP1 to send the keystroke to this window specifically? I'm OK with (and would prefer) sending this event to all Windows if that is possible so if APP2 changes in the future APP1 is not impacted.
I'm fairly new to Windows Programming so all help and insight is appreciated.
Thanks in advance.

Hi,
you should not send anything to "all windows" or "all applications". A lot of applications and windows are meant for human interaction only, and may suddenly display a dialog, where some of not all keys get interpreted the same as clicking the OK button. You cannot possibly want that.
you should send a keystroke or a sequence of keystrokes to a single window, after making sure you got the right window; and even that is not always fool proof, as it may change soon after you've checked.
There are a couple of ways to do it:
- System.Windows.Forms.SendKeys.SendWait() sends keys to the active app and window;
- SendMessage() could be used to send regular Windows messages such as WM_KEYDOWN and WM_KEYUP.
The former is managed but unsafe as, even when you get the ForeGroundWindow's title text and check it, the active window may change suddenly; the latter is a bit harder to use but should always be OK. I use both, and choose depending on circumstances.
