# V3044\. WPF: writing and reading are performed on a different Dependency Properties\.

The analyzer detected a possible error related to dependency property registration\. The property that performs writing into/reading from properties was defined incorrectly\.

```cpp
class A : DependencyObject
{
public static readonly DependencyProperty CurrentTimeProperty =
DependencyProperty.Register("CurrentTime", ....);
public static readonly DependencyProperty OtherProperty =
DependencyProperty.Register("Other", ....);

public DateTime CurrentTime {
    get { return (DateTime)GetValue(CurrentTimeProperty); }
    set { SetValue(OtherProperty, value); } }
}
....
```

Because of copy\-paste, the methods GetValue and SetValue, used in the definitions of the get and set access methods of the CurrentTime property, work with different dependency properties\. As a result, when reading from CurrentTime, the value will be retrieved from the CurrentTimeProperty dependency property, but when writing a value into CurrentTime, it will be written into 'OtherProperty'\.

A correct way to address the dependency property in the code above is as follows:

```cpp
public DateTime CurrentTime {
    get { return (DateTime)GetValue(CurrentTimeProperty); }
    set { SetValue(CurrentTimeProperty, value); } }
}
```
