Folderbrowserdialogがwindows7 environment で Drivers されたfolderを appropriate ないように to express things like

A つの bank internal システムがupdateして, そもそもxpシステムの, adjust で to たのに.

Windows7の, Folderbrowserdialogがうまく してなかった.

Adjust べて fruit が, Shi Fang ない. Windows systemの exists bugです.

Color 々 survey けて, として two つの 's really into 対応 square needle があります.

1, windowチーム opened Souel されたwindowsapicodepackをdownloadして,

そのmicrosoft.windowsapicodepack.dialogsを reference 前転して開脚座り, the following example にするばよい.

Commonopenfiledialog dialog = new Commonopenfiledialog (); Dialog.            InitialDirectory = @ "C:\Users\wangj\Documents\WeChat files\wxid_mw93g8weqm3e11\msg"; Dialog.            Isfolderpicker = true; if (dialog. ShowDialog () = = Commonfiledialogresult.ok) {TextBox1.Text = dialog.            FileName; }

2, Windows apiを use 前転して開脚座り.
