早期VB4的控制項何處尋？
常常在BBS上看到有人問這樣的問題：為什麼我用VB5的完全安裝，還是沒有找到 Sheridan 3D Control？
其實VB5已經不再主動安裝某些控制項，但VB5還是支援這些控制項，只是必須手動安裝，方法是在原版光碟的 Tools/Controls 目錄中，把你需要的Control複製到Windows的System下，再用 Tools/Controls 目錄中的Vbctrls.reg來註冊，就可以正常使用這些控制項。我覺得VB6可能不會再支援這些控制項，所以最好把那些舊的控制項，用具有類似功能的新控制項取代，以免你的專案無法在VB6執行；例如Graph32.ocx用M.S. Chart Control取代、Grid32.ocx用M.S. FlexGrid Control取代、Spin32.ocx用M.S. UpDown Control取代。
以下列出 Tools/Controls 目錄中的說明檔：
\Tools\Controls This directory contains all of the ActiveX Controls that shipped with Visual Basic 4.0 Professional and Enterprise Editions, which are no longer shipping with Visual Basic 5.0. AniBtn32.ocx Gauge32.ocx Graph32.ocx Gsw32.EXE Gswdll32.DLL Grid32.ocx KeySta32.ocx MSOutl32.ocx Spin32.ocx Threed32.ocx The \Tools\Controls\BiDi directory contains a Bi-directional version of Grid32.Ocx. If you have Visual Basic 4.0 Professional or Enterprise Editions installed on your machine, you should already have these ActiveX controls available to you in Visual Basic 5.0. Graph32.ocx has been updated to work properly in Visual Basic 5.0 and it requires two additional support files: gsw32.exe and gswdll32.dll. You must place the three files together in the \Windows\System directory or the control will not function properly. If you do not have these controls and wish to use these in Visual Basic 5.0, you can install them by: 1. Copy all of the files in this directory to your \WINDOWS\SYSTEM directory. 2. Register the controls by either Browsing to them in Visual Basic itself, or manually register them using RegSvr32.Exe. RegSvr32.EXE can be found in the \Tools\RegistrationUtilities directory. The command line is: regsvr32.exe grid32.ocx 3. Register the design time licenses for the controls. To do this, merge the vbctrls.reg file found in this directory into your registry. You can merge this file into your registry using RegEdit.Exe (Win95 or WinNT4) or RegEd32.Exe (WinNT3.51): regedit vbctrls.reg
