Now I wonder how can I programmicly (at run time) add event on key press to set this property to true?

I know how to do it through designer.

• in neutral state, _tail.next is null; the end of the list.
  
• the first thread executes the interlocked operation which succeeds and atomically sets _tail.next to something other than null.
  
• this causes the interlocked operation to fail on any other thread, and spin.
  
• the final assignment returns _tail.next to null (as a new list node has no next-node) and the list is coherent.
  

void addNode(Node newNode) {    // unsafe version
    newNode.next=head.next;
    head.next=newNode;
}
Node removeFirstNode() {    // unsafe version
    Node firstNode=head.next;
    head.next=firstNode.next;   // <<--- modified
    return firstNode;
}

void addNode(Node newNode) {    // safe version
    do {
        Node firstNode=head.next;
        newNode.next=firstNode;
    } while (firstNode!=Interlocked.ExchangeCompare(head.next,newNode,firstNode));
}

Node removeFirstNode() {    // safe version
    do {
    Node firstNode=head.next;
    } while (firstNode!=Interlocked.ExchangeCompare(head.next, firstNode.next, firstNode));
    return firstNode;
}

while (0!=Interlocked.ExchangeCompare(lockVar, 1, 0)) Thread.Sleep(1);
// do whatever you want now, even multiple stores
lockVar=0;

this.tabControl1.TabPages[0].Text="whatever you want";

this.tabControl1.TabPages[0].Name = this.textBox1.Text;
