C++/CLI¶

開発環境の設定¶

YdxCLI.h をプロジェクトフォルダにコピーします。
YdxCLI.h をプロジェクトに追加します。
ソースファイルに YdxCLI.h をインクルードします。
usingディレクティブを使ってYdxCLIを宣言します。

コントロール¶

変数¶

int id;

実行結果の表示¶

private: System::Void ResultShow(String^ title, int resultCode)
{
    StringBuilder ^resultString = gcnew StringBuilder(256);
    YdxCnvResultToString(resultCode, resultString);
    switch (resultCode)
    {
    case 0:
    case YDX_RESULT_AI_EXCEED_DATA_NUM:
    case YDX_RESULT_AI_EXCEED_BUF_SIZ:
        MessageBox::Show(resultString->ToString(), title, MessageBoxButtons::OK, MessageBoxIcon::Asterisk);
        break;
    default:
        MessageBox::Show(resultString->ToString(), title, MessageBoxButtons::OK, MessageBoxIcon::Hand);
        break;
    }
}

フォームロード¶

private: System::Void Form1_Load(System::Object^ sender, System::EventArgs^ e)
{
    // ユニット識別スイッチ
    unitSwitchComboBox->ResetText();
    unitSwitchComboBox->Items->AddRange(gcnew array<String^> { "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "B", "C", "D", "E", "F" });
    unitSwitchComboBox->SelectedIndex = 0;

    // 型名
    modelNameComboBox->ResetText();
    modelNameComboBox->Items->AddRange(gcnew array<String^> { "AIO-64/4/1B-USC", "AIO-60/4/1B-USC" });
    modelNameComboBox->SelectedIndex = 0;

    // レンジ
    rangeTypeComboBox->ResetText();
    rangeTypeComboBox->Items->AddRange(gcnew array<String^> { "-10 ～ +10V", "-5 ～ +5V" });
}

オープン¶

private: System::Void openButton_Click(System::Object^ sender, System::EventArgs^ e)
{
    int getId;
    int result = YdxOpen(unitSwitchComboBox->SelectedIndex, modelNameComboBox->Text, 0, &getId);
    if (result != 0)
        ResultShow("YdxOpen", result);
    else {
        unitSwitchComboBox->Enabled = false;
        modelNameComboBox->Enabled = false;
        rangeTypeComboBox->SelectedIndexChanged -= gcnew EventHandler(this, &Form1::rangeTypeComboBox_SelectedIndexChanged);
        rangeTypeComboBox->SelectedIndex = 0;
        rangeTypeComboBox->SelectedIndexChanged += gcnew EventHandler(this,&Form1::rangeTypeComboBox_SelectedIndexChanged);
        ResultShow("オープン", result);
        id = getId;
    }
}

レンジ切り替え¶

private: System::Void rangeTypeComboBox_SelectedIndexChanged(System::Object^ sender, System::EventArgs^ e)
{
    int result = YdxAiSetRange(id, rangeTypeComboBox->SelectedIndex);
    if (result != 0)
        ResultShow("YdxAiSetRange", result);
}

アナログ入力¶

private: System::Void inputButton_Click(System::Object^ sender, System::EventArgs^ e)
{
    const int CHANNEL_NUM = 6;
    float data[CHANNEL_NUM];
    int result = YdxAiInputVolt(id, 0, CHANNEL_NUM, data);
    if (result != 0)
    {
        ResultShow("YdxAiInputVolt", result);
        return;
    }

    String^ txt = "";
    for (int channel = 0; channel < CHANNEL_NUM; channel++)
    {
        txt += "CH" + channel.ToString() + " : " + data[channel].ToString(" 0.000;-0.000")->PadLeft(7) + "V" + Environment::NewLine;
    }

    dataTextBox->Text = txt;
}

クローズ¶

private: System::Void closeButton_Click(System::Object^ sender, System::EventArgs^ e)
{
    unitSwitchComboBox->Enabled = true;
    modelNameComboBox->Enabled = true;
    int result = YdxClose(id);
    if (result != 0)
        ResultShow("YdxClose", result);
    else
        ResultShow("クローズ", result);
}

フォームクローズ¶

private: System::Void Form1_FormClosing(System::Object^ sender, System::Windows::Forms::FormClosingEventArgs^ e)
{
    int result = YdxClose(id);
    if ((result != 0) && (result != YDX_RESULT_NOT_OPEN))
    {
        ResultShow("YdxClose", result);
    }
}
