Hi,

I am trying to browse to a file location on the client side using WEBUTIL_FILE.FILE_OPEN_DIALOG() package using forms 10g ...
But it's not getting through .

Code snippet:
/* when-button-pressed trigger of Browse button */

:B_Main.TI_File:=WEBUTIL_FILE.FILE_OPEN_DIALOG (L_directory_name,
L_file_name,
L_file_filter,
L_title) ;

I am getting one error message like ; 'Please Ackowledge' after which it is stops ....

Any idea how to deal with this error,or is there any other way to browse to a file on client side through a form on the server ...
