Interrupt a loop with toggle button

Question

I have a tcpclient and tcpserver two different csharp programs.

In tcpclient program I have created a toggle button. This toggle button when switched on creates a tcpclient and should continuously send data to the tcpserver. I have created a for loop for sending data continuously.

When toggle button is switched off data transfer should be stopped i.e. control should break out of for loop.

Can you please advise me about how can I make toggle button to initiate and interrupt the for loop?

It didn't work because when the program control is inside for loop any other changes like switching off toggle button are not being recognised by the program. May be I have to use two different threads.

Hi Declare a global bool variable called ' OnOff '. Initialize with false. In for loop for(.......) { if(OnOff) { transfer; } else break; } Assign the OnOff variable value true if toggle button [ checkbox ] is checked else false. To craete toggle button CheckBox checkBox1 = new System.Windows.Forms.CheckBox(); checkBox1.Appearance = System.Windows.Forms.Appearance.Button; It will work i guess.
