GOAL:
Is it possible for a .NET Open Client to check if an AppServer is still running without making an AppServer calls?
GOAL:
How to check if the AppServer is available from a C# application without making AppServer calls?
FACT(s) (Environment):
OpenEdge 10.x
Windows
FIX:
The only way to check the availability of the AppServer from a .NET client is to make an AppServer call. If the connection to the AppServer is not valid, the .NET client needs to catch the exception.
Try
' Send a request to the AppServer to get the Customer Name
m_custNum = CInt(txtCustNum.Text)
custNum.Value = m_custNum
m_order.FindCustomerByNum(custNum, custName)
.
.
.
Catch procEx As Exception
.
.
.
End Try
