Thread: Open dialog box issue

Hi,

i am using the GetOpenFileName and "OFN_FILEMUSTEXIST | OFN_NONETWORKBUTTON | OFN_PATHMUSTEXIST" flags to enable the User to select a file of any type, but when i try to open a file with URL extension the dialog box hangs up( not responding ) !!

Can you tell me please, how can i fix this issue?

Thanks in advance.
