System.FormatException: The format of the input string is incorrect.

The error occurs because the `Convert.ToDouble()` method is unable to parse the value in `m_txt_Shutter.Text` as a valid double. To fix this error, you can add error handling to handle cases where the input string cannot be converted to a double.

Here is an updated version of the code with error handling:

try
{
    if (!m_listCCamerInfo[m_nOperateID].m_bIsOpen)
    {
        return;
    }

    if (double.TryParse(m_txt_Shutter.Text, out dShutterValue))
    {
        m_listCCamerInfo[m_nOperateID].m_objIGXFeatureControl.GetFloatFeature("ExposureTime").SetValue(dShutterValue);
        strValue = dShutterValue.ToString("F2");
    }
    else
    {
        // Handle invalid input here
        // For example, display an error message or set a default value
    }
}
catch (Exception ex)
{
    // Handle any other exceptions here
    // Log the exception or display an error message
}

In this code, `double.TryParse()` is used to attempt to parse the input string as a double. If the parsing is successful, the `dShutterValue` will be assigned the parsed value, and you can proceed with setting the value and converting it to a formatted string. If the parsing fails, you can handle the invalid input case as needed.
