Get WPF window by hWnd

Question

I am looking to get a WPF window and traverse it\'s controls. I\'m able to get the hWnd and i\'ve found other posts on traversing the controls using a DependencyObject. How

Answer 1

After you get the window itself (as Marat points out how to do that) you need to search the visual tree. Here are two helper functions

find all children of a type

public static IEnumerable FindChildren(this DependencyObject source) where T : DependencyObject
    {
      if (source != null)
      {
        var childs = GetChildObjects(source);
        foreach (DependencyObject child in childs)
        {
          //analyze if children match the requested type
          if (child != null && child is T)
          {
            yield return (T)child;
          }

          //recurse tree
          foreach (T descendant in FindChildren(child))
          {
            yield return descendant;
          }
        }
      }
    }

to find a child by name:

 public static T FindChild(DependencyObject parent, string childName)
       where T : DependencyObject
    {    
      // Confirm parent and childName are valid. 
      if (parent == null) return null;

      T foundChild = null;

      int childrenCount = VisualTreeHelper.GetChildrenCount(parent);
      for (int i = 0; i < childrenCount; i++)
      {
        var child = VisualTreeHelper.GetChild(parent, i);
        // If the child is not of the request child type child
        T childType = child as T;
        if (childType == null)
        {
          // recursively drill down the tree
          foundChild = FindChild(child, childName);

          // If the child is found, break so we do not overwrite the found child. 
          if (foundChild != null) break;
        }
        else if (!string.IsNullOrEmpty(childName))
        {
          var frameworkElement = child as FrameworkElement;
          // If the child's name is set for search
          if (frameworkElement != null && frameworkElement.Name == childName)
          {
            // if the child's name is of the request name
            foundChild = (T)child;
            break;
          }
        }
        else
        {
          // child element found.
          foundChild = (T)child;
          break;
        }
      }

      return foundChild;
    }

How can I find WPF controls by name or type?
