Winrunner - Handling Dynamic objects

Most of the Winrunner users are using playback methods to develop the scripts. Here I have given two code snippets to handle dynamic objects.

Code: To find Image

public function SetToSearchPage() {
web_sync(200);
set_window("{class: window, MSW_class: html_frame,active:1}",60);
web_image_click("{class: object,MSW_class: html_rect,html_name: \"search_gnav.gif\"}", 0, 0); 
web_sync(250);
}   #End of SetToSearchPage()

Code: To find correct Window, after clicking a link

public function SetTitle() {
set_window("{class: window, MSW_class: html_frame,active:1}",20);
win_get_info("{class: window, MSW_class: html_frame,active:1}","html_name", sWinTitle);
#report_msg("RE Source Page Title is " & sWinTitle);

if (index(sWinTitle, "Users") != 0) {
set_window("My Users",40);    
#report_msg("My Users page has been identified");
} else if (index(sWinTitle, "Group") != 0) {
set_window("Group",20);
#report_msg("Group  page has been identified");
}  else if (index(sWinTitle, "View Agenda") != 0) {
set_window("View Agenda",30);
#report_msg("View Agenda  page has been identified");
}else {
report_msg("Couldn't find the window in GUI MAP is " & sWinTitle);
}
}
