4. 按 Install 按鈕繼續安裝程序 5. 選擇 No, I will restart the computer later 並且按 Finish 按鈕 1 2 在 Visual Basic 2005.NET 中使用 ActiveX Control (OCX), Ver.1.0, May/2009, Copyright By ICP DAS ---- 3

2 安裝硬體裝置請依照下列步驟 : 1. 關掉電腦電源 2. 打開電腦機殼 3. 選擇未使用的 PCI 插槽, 並移除保護裝置 4. 小心插入板卡至 PCI 插槽中, 並以螺絲固定住 5. 裝回電腦機殼 6. 啟動電腦電源進入 Windows 後, 請依照提示訊息完成 Plug & Play 在 Visual Basic 2005.NET 中使用 ActiveX Control (OCX), Ver.1.0, May/2009, Copyright By ICP DAS ---- 4

3 使用 ActiveX Control (OCX) 在 VB.NET 2005 上使用 ActiveX Control, 請依照下列步驟 : 1. 新增 ActiveX Control (OCX) 到 VB.NET 2005 工具列上在功能選單上, 選擇 Tools/ Choose Toolbox Items... 1 2 在 Visual Basic 2005.NET 中使用 ActiveX Control (OCX), Ver.1.0, May/2009, Copyright By ICP DAS ---- 5

2. 點選 COM Components 對話框列表裡的 PIODIOX Control 並且按 OK 按鈕 1 2 3 3. 工具列將會顯示 PIODIO (PCI Card OCX) 的元件圖示在 Visual Basic 2005.NET 中使用 ActiveX Control (OCX), Ver.1.0, May/2009, Copyright By ICP DAS ---- 6

4. 產生一個新的專案並且新增 PIODIO (PCI Card OCX) 元件到此專案中 1 2 注意 : 請注意, 在.NET 環境上, 所有 OCX 控制元件不能正確處理 Array 型態的參數因為它們是不同的子系統在.NET 環境使用 Array 型態的參數時, 你必須直接呼叫 Win32 DLL 函式來代替使用 OCX 控制元件在 Visual Basic 2005.NET 中使用 ActiveX Control (OCX), Ver.1.0, May/2009, Copyright By ICP DAS ---- 7

4 撰寫 DIO 程式範例設計 DIO 程式, 在程式中呼叫 OCX 函式請依照下列步驟 : 1. 設計介面 : etotalboar ComName ListTest btnactive PIODIOX1 btnexit 在 Visual Basic 2005.NET 中使用 ActiveX Control (OCX), Ver.1.0, May/2009, Copyright By ICP DAS ---- 8

2. PIODIOX 函式列表, 如下 : property property property BSTR ErrorString; short ErrorCode; short ActiveBoard; short DriverInit(); long GetConfigAddressSpace(short naddrnum); short GetDllVersion(); short GetDriverVersion(); short InputByte(long IBaseAddr); long InputWord(long IBaseAddr); void OutputByte(long IBaseAddr, short noutputdata); void OutputWord(long IBaseAddr, long IOutputData); short DigitalIn(short nport); void DigitalOut(short nport, short noutputvalue); void SetCounter(short ncounterno, short ncountermode, long ncounterval); long ReadCounter(short ncounterno, short ncountermode); long ResetlrqCount(); void Installlrq(long* hevent, short nlrqsource, short nactivemode); void Removelrq(); void GetlrqCount(); long D48Freq(); void D48Installlrq(long* IHandle, short nlrqmask, short nactivemode); void D48Removelrq(); long D48Getlrqcount(); void SavelrqActiveFlag(); short GetlrqActiveFlag(short FlagNum); void DriverClose(); 更詳細 OCX 函式資訊請參考 : ActiveX Control for PCI series boards User's Manual http://ftp.icpdas.com/pub/cd/iocard/pci/napdos/pci/manual/ocx%28activex%29_manual_for_pci _pio_piso_cards.pdf 在 Visual Basic 2005.NET 中使用 ActiveX Control (OCX), Ver.1.0, May/2009, Copyright By ICP DAS ---- 9
