FileSubType Property

Applies to TestComplete 14.91, last modified on July 20, 2021

Description

The FileSubType property allows you to get additional information about a device driver, font file or virtual device file. This property returns 0 for a file of another type (for example, an executable).

Declaration

aqFileVersionInfoObj.FileSubType

Read-Only Property Integer
aqFileVersionInfoObj An expression, variable or parameter that specifies a reference to an aqFileVersionInfo object

Applies To

The property is applied to the following object:

Property Value

If the file is a device driver (that is, if FileType is VFT_DRV), the property returns one of the following constants defined in the Win32API object:

Constant Value Description
VFT2_UNKNOWN 0 Unknown driver type.
VFT2_DRV_PRINTER 1 A printer driver.
VFT2_DRV_KEYBOARD 2 A keyboard driver.
VFT2_DRV_LANGUAGE 3 A language driver.
VFT2_DRV_DISPLAY 4 A display driver.
VFT2_DRV_MOUSE 5 A mouse driver.
VFT2_DRV_NETWORK 6 A network driver.
VFT2_DRV_SYSTEM 7 A system driver.
VFT2_DRV_INSTALLABLE 8 An installable driver.
VFT2_DRV_SOUND 9 A sound driver.
VFT2_DRV_COMM 10 A communications driver.
VFT2_DRV_VERSIONED_PRINTER 12 A versioned printer driver.

If the file contains a font (that is, if FileType is VFT_FONT), the property returns one of the following constants defined in the Win32API object:

Constant Value Description
VFT2_UNKNOWN 0 Unknown font type.
VFT2_FONT_RASTER 1 A raster font.
VFT2_FONT_VECTOR 2 A vector font.
VFT2_FONT_TRUETYPE 3 A TrueType font.

If the file is a virtual device (that is, if FileType is VFT_VXD), the property returns the virtual-device identifier included in the virtual-device control block.

If the file is an application, a dynamic-link library, a static-link library or a file of an unknown type (that is, if FileType is either VFT_APP, VFT_DLL, VFT_STATIC_LIB or VFT_UNKNOWN), the property returns 0.

Example

The code below determines a file's sub-type using the type of the specified file.

JavaScript, JScript

function VersionInfoSample()
{
  var FileName = Sys.OSInfo.WindowsDirectory + "\\notepad.exe";
  var VerInfo = aqFileSystem.GetFileInfo(FileName).VersionInfo;

  Log.Message("File sub type: " + GetFileSubTypeStr(VerInfo.FileType, VerInfo.FileSubType));
}

function GetFileSubTypeStr(FileType, FileSubType)
{
  switch (FileType)
  {
    case VFT_VXD : return "a virtual device file with the " + FileSubType + " identifier.";
    default:
       switch (FileSubType)
       {
          case 0 : return "unknown.";
          case VFT2_DRV_PRINTER : return "a printer driver.";
          case VFT2_DRV_KEYBOARD : return "a keyboard driver.";
          case VFT2_DRV_LANGUAGE : return "a language driver.";
          case VFT2_DRV_DISPLAY : return "a display driver.";
          case VFT2_DRV_MOUSE : return "a mouse driver.";
          case VFT2_DRV_NETWORK : return "a network driver.";
          case VFT2_DRV_SYSTEM : return "a system driver.";
          case VFT2_DRV_INSTALLABLE : return "an installable driver.";
          case VFT2_DRV_SOUND : return "a sound driver.";
          case VFT2_DRV_COMM : return "a communications driver.";
          case VFT2_DRV_VERSIONED_PRINTER : return "a versioned printer driver.";
          case VFT2_FONT_RASTER : return "a rester font.";
          case VFT2_FONT_VECTOR : return "a vector font.";
          case VFT2_FONT_TRUETYPE : return "a TrueType font.";
          default: return "unknown.";
       }
  }
}
