How to check whether the SAP system is connected to .NET or not?

[Former Member]

I have developed a sample appln to check whether the .NET4.0 is connected to SAP or not....

I have added the references

SAPconnectionmanager.dll

sapnco.dll

sapnco_util.dll

Then I have created a application Config file for my window application, and added the apps setting

<configuration>

  <appSettings>

    <add key= "ServerHost" value="122.159.217.222" />

    <add key= "SystemNumber" value= "58"/>

    <add key="User" value="xxvi"/>

    <add key="Password" value="xxxxx"/>

    <add key="Client" value="00"/> //*Instance Number*//

    <add key="Language" value="EN"/>

    <add key="PoolSize" value="5"/>

    <add key="PeakConnectionsLimit" value="10"/>

    <add key="IdleTimeout" value="600"/>

  </appSettings>

</configuration>

Then I have added a code on Form load function

try

            {

                SAPSystemConnect sapCfg = new SAPSystemConnect();

                RfcDestinationManager.RegisterDestinationConfiguration(sapCfg);

                RfcDestination rfcDest = null;

                rfcDest = RfcDestinationManager.GetDestination("Dev");

                ;

            }

            catch (Exception ex)

            {

                label1.Text=ex.Message;

            }

After running this, the form is loading without error even if i give wrong username and password in apps setting.... Then how can i find the SAP system is connected???

Use "CreateFunction" and "Invoke" an ABAP function module with it.  That would be the easiest way to find out.

Hi Jeswin,

I am also trying to connect SAP-ECC through .net. Would you please tell me your method worked and you were able to ping and retrieve data? Thanks.

Doing that you are encouraging Jeswin to violate licensing agreement for the NCO 3. It's not permitted to redistribute it. You need to get your account on market place.

Hi Hynek Petrak!

Don't worry it won't happen at any cause!!

Use .Ping() on destination. This is the simplest.
