帮我改下代码。
我期望以树装形出当前所有窗口及窗口的所有控件（就像spy++一样)
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern int GetWindowText(HandleRef hWnd, StringBuilder lpString, int nMaxCount);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern int GetWindowTextLength(HandleRef hWnd);
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
private static extern bool EnumWindows(EnumThreadWindowsCallback callback, IntPtr extraData);
[DllImport("user32.dll", ExactSpelling = true)]
private static extern bool EnumChildWindows(HandleRef hwndParent, EnumChildrenCallback lpEnumFunc, HandleRef lParam);
private delegate bool EnumThreadWindowsCallback(IntPtr hWnd, IntPtr lParam);
private delegate bool EnumChildrenCallback(IntPtr hwnd, IntPtr lParam, TreeNode parentNode);
private bool EnumWindowsCallback(IntPtr handle, IntPtr extraParameter)
{
int num1 = GetWindowTextLength(new HandleRef(this, handle)) * 2;
StringBuilder builder1 = new StringBuilder(num1);
GetWindowText(new HandleRef(this, handle), builder1, builder1.Capacity);
Application.DoEvents();
listBox1.Items.Add(string.Format("父:{0} Title: {1}", handle, builder1.ToString()));
TreeNode RootNode = new TreeNode(builder1.ToString());
this.treeView1.Nodes.Add(RootNode );
EnumChildWindows(new HandleRef(this, handle), new EnumChildrenCallback(EnumChildWindowsCallback), new HandleRef(null, IntPtr.Zero));
return true;
}
private bool EnumChildWindowsCallback(IntPtr handle, IntPtr lparam, TreeNode parentNode)
{
int num1 = GetWindowTextLength(new HandleRef(this, handle)) * 2;
StringBuilder builder1 = new StringBuilder(num1);
GetWindowText(new HandleRef(this, handle), builder1, builder1.Capacity);
listBox1.Items.Add(string.Format("SubWnd:{0} Title: {1}", handle, builder1.ToString()));
TreeNode subNode = new TreeNode(builder1.ToString());
parentNode.Nodes.Add(subNode);
return true;
}
private void button1_Click(object sender, EventArgs e)
{ EnumThreadWindowsCallback callback1 = new EnumThreadWindowsCallback(this.EnumWindowsCallback);
EnumWindows(callback1, IntPtr.Zero);
}
private void MainForm_Load(object sender, EventArgs e)
{
TreeNode node = new TreeNode(this.Text);
treeView1.Nodes.Add(node);
AddCtls(node, this);
}
public void AddCtls(TreeNode node, Control pctl)
{
foreach (Control ctl in pctl.Controls)
{
TreeNode curNode = new TreeNode(ctl.Text + " - " + ctl.GetType().ToString());
node.Nodes.Add(curNode);
AddCtls(curNode, ctl);
}
}
