calling a windows component from a separate class

Question

hi i'm doing a windows application and i've created a separate class from which i need to access the windows components like textbox listbox and the like from this class. may i have some advice on how to access these components from other classes? the keyword 'public' does not seem to help. thanks in advance.

You can pass a reference of the object to a method in the separate class (using ref keyword). That allows you to directly modify the object's properties.

hi i understood what you mean by using the following. private System.Windows.Forms.TextBox txtPassword; public System.Windows.Forms.TextBox TxtPassword { get{return txtPassword;} //read property set{txtPassword = value;} //write property } however i cannot use this public property when i'm coding in my separate class. in order for me to access this property i need to refer to an object out of the windows class and this object was already created/instantiated when i run my windows application by the following commmand. Application.Run(new MainForm()); i can't possibly create another new instance of the windows class whenever i need to access my UI components. anyway it didn't work even if i create another instance of the windows class. i would greatly appreciate any suggestions to overcome my problem as i've been stuck with this for a week or so already and i can't progress any further if i can't solve this. thanks in advance! regards.
