So, when I press scan button, it will take some time to get the table entries from MIB thro' SNMP protocol.Heres the problem. Till to get datas, the screen get idel.
So, I want to use a Dialog box that displays " you are in scanning mode.Please wait". and this dialog box automatically closed when the user get datas.
How can i fix this problem?.
