Use a class or static variable which you can set each time through this code; something like:

C++

private: System::Void btnMul_Click(System::Object^  sender, System::EventArgs^  e) {
    static bool isMul = false;
 
    if(isMul == false){
        ice->(isMul, 8000, 6000);// I am not sure of the validity of this statement
        unsigned long data = 10;
        unsigned long value;
        value=5*data;
        String^ str = value.ToString();
        textBox1->Text=str;
        
        isMul=true;
    }
    else
    {
        ice->(isMul, 8000, 6000);// I am not sure of the validity of this statement
        textBox1->Text = "";
        isMul=false;
        
    }
