    I have a for loop
    and I have 25 var named Case_P1 to Case_P25 in type double
    I wanna do it simple as i can i just want show this var value in 25 TextBox named
    ECase_1 To ECase_25:
    So, i tought it was :
    Code:
    for (int i =1;i<=25;i++)
    {
    
    char *name= ("CaseP" + String(i)).c_str();
    double *NV = reinterpret_cast<double*> (name);
    E_Case_(i)->Text = String(*NV);
    // I want this Case_P(i); Not supposed to be hard?!?!
    //Something like that!
    E_Case_(i) = Case_P(i);
    }
    
    
    So, i can't use vector or tabs, is an already implemented code! i can't change var types.
    thx
    Thx you !
