Question

I am Using same function from many places…

for example below function

Public Sub getUser(ByVal Name as string)
      dim myName=Name
         .......
      insert(myName)
End Sub

I am using this function from so many places…
I have doubt should this function override this myName values with latest function call?

Suppose i called getUser(“ABC”) so value of myName is now ABC now sudden all call getUser(“XYZ”) so at insert(myName) will it insert(“ABC”) or insert(“XYZ”)??

I need it to be insert(“ABC”) and then insert(“XYZ”)

You can use locking to make sure only one thread does something at a time

//declare an object for locking
Dim lockObjcect As New [Object]()

    Public Sub getUser(ByVal Name as string)
        SyncLock lockObjcect
          dim myName=Name
              .......
          insert(myName)
        End SyncLock
    End Sub

With the locking, now only one thread will be able to execute the code between SyncLock and End SyncLock this means First ABC will be inserted and then XYZ will be inserted
