I have an edit box named IDCTextFormula in a window. Is this the easiest way to change its text?:

CEdit* formula = (CEdit*)GetDlgItem(IDCTextFormula);
formula->SetWindowText("test");

Likewise, with any control, do you have to go through all that work just to access a method?

If you do not want to use GetDlgItem, you can try member variables.
Using class wizard, let us say you associate a member variable of type CString
with the edit control IDCTextFormula. Let us say the name of this variable is
m_edit_textformula.
In your code where you want to change the contents of the edit control, you write
m_edit_textformula="test";
UpdateData(FALSE);

The other method could be by using class wizard and associating a control type
of variable (of type CEdit) with the edit control IDCTextFormula. Let us this is called m_editctrl. Then in your code you write:
m-editctrl.SetWindowText("test");

Hope you will find this an easier method.

Thanks.

It all depend on your choice. You can define a variable for it (with the help of Class Wizard) or access it through GetDlgItem method. Usually I use Class Wizard for such type of controls which I access number of times, where as I have to access a control in my application only few time I use

(CEdit* GetDlgItem(IDCTextFormula))->SetWindowText("Test");

In your case, you can also define a CString type varaiable with your CEdit control through Class Wizard, and after moving new value just call UpdateData(FALSE). This will update your Edit Box with new value.
