ipc with remoting problem - .NET (Core and Framework) Discussion Boards

hey thats fine, I'll check it. really thanks for your reply.
actually i have again post my problem briefly. Please reply if get any idea

Hey folks, I am doing some preliminary research for a fairly large forms/data-driven business application I am due to develop. There are 4 basic requirements for this application:

1. Can install/run app on local PC or as a hosted application (access via Web Browser to our hosted server). This includes the Database.
2. The local version may be a Windows-only application.
3. The hosted version must run cross-browser (IE and Firefox minimum).
4. The local version must have a simple installer (via Web or CD) and can Auto-Update.

I have a modest amount c#, ASP.NET and SQL experience but am overwhelmed by the choice of .NET technologies available and would like some opinions. Ideally I would like just one codebase but the more I look at it, the less feasible that seems. Maintaining 2 apps doesn't sound so much fun.

My first thought was an ASP.NET app that could be packaged with UltiDev Cassini and deployed locally but I'm not sure it's robust/secure enough (thoughts?) Other choices seem to be:

Local
- WinForms
- WPF or XBAP
- ASP with Cassini or Web Deployment tool.

Remote/hosted
- XBAP
- ASP.NET/MVC/Ajax
- Silverlight

I've noted that you can potentially deploy a WPF app natively and as a XBAP using Prism, like to hear thoughts on that.

Then there's the data access strategy, which I'm not sure about either! Laugh | :laugh:

Potentially you could look at using Silverlight and WPF. It's possible to share quite a bit of code between Silverlight and WPF if you know the tricks and gotchas. Take a look at the work we've done on Onyx[^] to get some ideas.

Thank you very much Pete, I'm going to take a closer look at Onyx, Prism and Caliburn and figure out how they relate.

Appreciate any other comments and opinions from folks. Big Grin | :-D

I'm biased towards Onyx - it solves problems that Prism and Caliburn ignore, and I am the person working on the Silverlight code of Onyx. Wink | ;)

I'm trying to hook the ReadFile API like FileMon does.
Do you have an example of ReadFile?

Please help me .....

Please don't cross post. It's bad form.

Hi all, I'm trying to move my app from tcp to ipc, but i keep getting

Failed to connect to an IPC port: the System cannot find the file specified.

The server is a service running with Local System account.

Client and server work fine with tcp. Those are my configuration files:

Client:

<configuration>
  <system.runtime.remoting>
    <application>
      <channels>
        <channel ref="IPC" portName="2001" timeout="900000" name="mwchannel">
          <clientProviders>
            <formatter ref="binary" />
          </clientProviders>
          <serverProviders>
            <formatter ref="binary" typeFilterLevel="Full" />
          </serverProviders>
        </channel>
      </channels>
      <client>
        <wellknown type="MW.Remote.RemoteConnection, RemoteConnection" url="IPC://MWPort/MWServer/RemoteConnection.rem" />
      </client>
    </application>
  </system.runtime.remoting>
</configuration>

Server

<configuration>
  <system.runtime.remoting>
    <application name="MWServer">
      <channels>
        <channel ref="ipc" portName="MWPort" authorizedGroup="Everyone" timeout="3000">
          <serverProviders>
            <provider ref="wsdl" />
            <formatter ref="soap" typeFilterLevel="Full" />
            <formatter ref="binary" typeFilterLevel="Full" />
          </serverProviders>
          <clientProviders>
            <formatter ref="binary" />
          </clientProviders>
        </channel>
      </channels>
      <service>
        <wellknown mode="Singleton" type="MW.Remote.RemoteConnection, RemoteConnection" objectUri="RemoteConnection.rem" />
      </service>
    </application>
    <customErrors mode="Off">
    </customErrors>
  </system.runtime.remoting>
</configuration>

What is strang to me is that the same error appears if I shut down the server, so I suppose that the client is not even able to 'see' the server. Does someone spot any error or knows about possible causes?
Thank you!

Thank you

If you are talking WinForms there are Closing and Closed events you can handle.

If this is ASP.NET then I don't think there is anything you can do (you may get an answer on the ASP.NET forum)

You're absolutely right Colin. All you could tell is that the form was closed somehow.

Hi,
There is no straight forward solution to this. However, checkout the following link:

Either you love IT or leave IT...

i hav written following code for login page..

SqlConnection con=new SqlConnection("Data Source=.\\sqlexpress;Initial Catalog=MLM;Integrated Security=True");
SqlCommand com=new SqlCommand("select UserName,Login_Password from RegistrationForm",con);

con.Open();
SqlDataReader rs = com.ExecuteReader();

while (rs.Read())
{
if ((rs[0].ToString() == T1.Text) && (rs[31].ToString()== T2.Text))
{

string s1 = T1.Text;
Response.Redirect("HOME.aspx?UserName=" + s1);

return;
}
else
{
Response.Write("Unsuccessful Login");

T2.Text = "";
T2.Focus();
}
}
rs.Close();
com.ExecuteNonQuery();
con.Close();

bt the error occured is Array index out of bound....bt when i take rs[1] instead of rs[31],then error is like unsuccessful login

Well, that's what your code is supposed to say when you type a wrong password. This is what happens, whit rs[2];

Here you check whether username and password combination are present in the database

if ((rs[0].ToString() == T1.Text) && (rs[31].ToString()== T2.Text))

If they don't exist, then the computer will execute the else-part;

else
{
Response.Write("Unsuccessful Login");

T2.Text = "";
T2.Focus();
}

There is your message. Shouldn't happen when you use a password that is in the database.

Now, when you simply change the number of the index to 31, your code becomes broken; there aren't 31 fields in that query, so it tries to read from memory that ain't there.

select UserName,Login_Password from RegistrationForm

returns two fields, not 31.

I are troll Smile | :)

your code is good and validate user and password but is not optimazed.
exception occered in

if ((rs[0].ToString() == T1.Text) && (rs[31].ToString()== T2.Text))

because in your query you select only two columns from table
and sql server return two selected columns but use number 31 for index.
when you read data by SqlDataReader you can use indexed mode

sqlDataReader[item index]

item index must one less from columns count or one less from sqlDataReader.FieldCount
to solve your problem change your if to

if ((rs[0].ToString() == T1.Text) &amp;&amp; (rs[1].ToString()== T2.Text))

for indexing item in datareader and dataset it not importent how many columns is in table it importent how many columns are selected in query

Hello everyone ,

I have an issue i.e, I am using crystal report(version 11 release 2) in my windows applications developed in vb.net (2005)and sql server(2005) as backend . In one of the forms i placed one reportviewer control,

crystal report taking long time for preview & print(nearly 2 minute) .
please any one help me to getout of this

Dim rpt As New CrystalReport1() 'The report you created.
        Dim myConnection As SqlConnection
        Dim MyCommand As New SqlCommand()
        Dim myDA As New SqlDataAdapter()
        Dim myDS As New Dataset1() 'The DataSet you created.

        Try

            myConnection = New SqlConnection("Data Source=localhost;Integrated Security=SSPI;" & _
                                             "Initial Catalog=northwind;")
            MyCommand.Connection = myConnection
            MyCommand.CommandText = "SELECT * FROM Customers where cid=10"
            MyCommand.CommandType = CommandType.Text
            myDA.SelectCommand = MyCommand

            myDA.Fill(myDS, "Customers")
            rpt.SetDataSource(myDS)
            CrystalReportViewer1.ReportSource = rpt

        Catch Excep As Exception
            MessageBox.Show(Excep.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
        End Try

I asked This Question Already but No one ready solve my Problem.
Please tell how to increase My Crystal report Preview ? My staff scolding me. please
Advance thnx.

First, try the samples that come with CR; you'll notice that these aren't speedmonsters either. CR has lots of features, and they all take time to load. I'm hoping that they'll soon release some lightweight version.

Also, check your query, things like indexes. Measure how much time it takes to execute that query. CR won't be faster than the server.

Last, try preloading as much as you can. Perhaps you could move the loading of the query to the initialization of the form, in a backgroundworker. It doesn't save much time, but it might be just enough.

What is .net compact? How difference between .net framwork? Confused | :confused:

A subset of the .NET framework. There's not enough room for the entire .NET Framework on a mobile device, so they created a compact edition for Windows Mobile. You can read more about it here[^].

It offers less functionality than it's big brother.

Hi,

I want the steps or creating store procedures....and it should be written

1. Stored procedures have absolutely zero to do with the .NET framework. You should have asked this in the database forum.
2. You need to identify what database the stored procedure is for. Each DB has it's own unique syntax for stored procedures.
3. You could get the answer quicker just by googling for create stored procedure with the DB identified above.
4. The steps for creating stored procedures normally involve using a text editor, of some description, a design and some tables.

It hardly matters to others about what do you want. But in codeproject, we all would like to help others who need help to solve a problem. I would like to suggest you to go through some good books or visit the following links which can help you to get started with Stored Procedure:

Hi All,
I have a situation where I need to do some custom message filtering.
Unfortunately I need more functionality than provided by the
IMessageFilter system or by overriding a Form's wndproc() method.
What I need is to be able to run code before and after a message is
processed and optionally drop selected messages.

As I understand it:

The IMessageFilter system only allows filtering out selected messages
(can't run code after they have been processed)

A Form's wndproc method only sees messages destined for that form. (I
need to handle all messages for the entire application)

In an unmanaged application say in visual c++ it would be a simple
matter of implementing ones own getmessage/dispatchmessage loop. In
the dotnet framework the actual message loop is implemented in native
code and is inaccessible to the programmer.

Does anyone know a solution for this?

Regards,
Felix

Unfortunately, the only thing you can do outside the form is use Application.AddMessageFilter to add your own filter, and (as you've surmised), this only works on capturing a message before it is dispatched to the window. What you could possibly do (and this would be one heck of a hack), is use a combination of AddMessageFilter and a Mediator to control what happens. What you'd do is hook into the WndProc of each form, and pass the details to the mediator to work out whether or not the message could be processed.

Thanks for your answer. I think I may have to add a custom BaseForm class that overrides the wndproc and which all of my Forms inherit from. That way I could insert global message processing which would be similar to writing a custom message loop.
