A customer set the OFN_<\/code>NO\u00adNETWORK\u00adBUTTON<\/code> option in the OPEN\u00adFILE\u00adNAME<\/code> structure, but it stil shows the Network<\/i> item in the navigation pane.<\/p>\n

There are a number of flags in the OPEN\u00adFILE\u00adNAME<\/code> structure which harken back to the old Windows 3.1-style dialog box. In Windows 3.1, the Open<\/i> dialog had a button labeled Network<\/i> that appeared next to the drives combo box. Clicking it let you map a new network drive. The OFN_<\/code>NO\u00adNETWORK\u00adBUTTON<\/code> flag hides that button.<\/p>\n

But if you’re using the new Explorer-style Open<\/i> dialog, there is no Network<\/i> button to begin with, so there’s no button to hide.<\/p>\n

While it’s true that there is a Network<\/i> item in the navigation pane, that is not the thing that the OFN_<\/code>NO\u00adNETWORK\u00adBUTTON<\/code> flag controls. The purpose of the flag was not to hide the network; it was merely to hide the button that lets you map a new network drive. And since the Explorer-style dialog doesn’t have such a button in the first place, the flag is redundant.<\/p>\n

There’s another flag left over from the Windows 3.1 dialog: OFN_<\/code>HIDE\u00adREAD\u00adONLY<\/code>. The original Windows 3.1 dialog had a separate check box called Read-only<\/i>, but the Explorer style dialog doesn’t have that check box. Instead, the Open<\/i> button is a split button, with options Open<\/i> and Open as read-only<\/i>. In this case, the Open<\/i> dialog box was able to map the old flag to a corresponding feature in the new dialog.<\/p>\n
