Jayasree,

This method will show a window where you can select a file that you are trying to upload. If you are trying to upload the file and want to give the user to browse and select the right file, you use this.

Its just like your Open command in your word.

Regards,

Ravi

Class CL_GUI_FRONTEND_SERVICES uses t access presentation server like access files in the system.

file_open_dailog opens the windows open file dialog box . It is similar to WS_FILENAME_GET function module. So that you select required file.

Hi,

It is a STATIC PUBLIC method (OR CLASS METHOD) defined in class CL_GUI_FRONTEND_SERVICES which means you can call this method with class name and there is no necessity to create an object.
