FindWindow - will get you close; you do want a window handle but you won't for sure know how to find it. Better would be do use EnumWindows.Here's an example of a routine you can run every second or two that will give you a ton of info about every single window on the system, then you can analyze it. You can check the type of window, the text in it, get the buttons, and send a click message to the right one. It will let you do everything you are hoping to be able to do. To get the text you send a wm_gettext and for the button you may get away with wm_click. Sorry for the C. the next best example I could find was in LISP. Take time to read the code, you will see what the idea is. The Matching functions help determine if the text is right without knowing it exactly. If you can manage to do this in c# I am betting you will get a lot shorter solution. (can you use LINQ on the output of EnumWindows?;-) <pre><code>#include <string.h> #include <stdio.h> #include <stdlib.h> #include <windows.h> #include "resource.h" #define ET_STARTUP 1 #define ET_WINDOWOPEN 2 #define ET_RUNEND 3 #define ET_USEREVENT 4 #define M_STAR 1 #define M_QUESTION 2 typedef struct WindowList_s { int iScriptLine; HWND hwnd; char *stName; char *stTitle; char *stClassName; char *stParentName; struct WindowList_s *wlParentPtr; char *stChildName; struct WindowList_s *wlChildPtr; int bWarned; struct WindowList_s *next; } WindowList_t; //////////////// extern long g_runids[]; extern WindowList_t *g_windowlist; extern EventList_t *g_eventlist; char stWTx[2000]; char stWCl[200]; char stPTx[2500]; char stPCl[200]; int bEventEntry=0; // means we're inside of processing an event.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
