Only Plug and Play drivers can issue IOCTL_STORAGE_QUERY_PROPER<wbr />TY requests. Legacy drivers should use IOCTL_SCSI_GET_INQUIRY_DAT<wbr />A and IOCTL_SCSI_GET_CAPABILITIE<wbr />S to get inquiry and capabilities data.<br />

Hello,<br />
anybody here who has experience with &nbsp;IOCTL_STORAGE_QUERY_PROPER<wbr />TY? I tried a call with _STORAGE_ADAPTER_DESCRIPTO<wbr />R to get PIO mode. But this always return FALSE, even if I disable DMA in Device Manager.<br />

IOCTL_STORAGE_QUERY_PROPERTY

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.

Microsoft Development

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.
