chieldHwnd= FindWindowEx(parentHwnd, chieldHwnd, "obj_EDIT", null);

int length = SendMessage(chieldHwnd, WM_GETTEXTLENGTH, (IntPtr)0, (IntPtr)0);

if (length > 0)
{
StringBuilder sb = new StringBuilder(length);
int numChars = SendMessage(chieldHwnd, WM_GETTEXT, (IntPtr)(length + 1), sb);
listBox1.Items.Add("in Textbox : " + sb);
}

this code takes a text in textbox but form has 2 textboxes and it takes last textbox's text how can i get the specified text.

username -------------
password -------------

both of them empty

and it takes allways password's text of textbox

thanks for everything i have...

You need to call FindWindowEx in a loop passing previous values as hwndChildAfter. The loop should end when FindWindowEx returns NULL.

By the way, winapi questions should be asked here: Visual C++ / MFC[^]

Why are you adding hwnds to the listbox? I thought you wanted to get text from them.

You are returning only the last one. Find text for all the hwnds you get by the loop.

Well, you get text by sending messages to the control identified by the hwnd, don't you? So send those messages to all the childhwnds you get.
