Project: Version Information Component
Unit: PJVersionInfo
Class: TPJVersionInfo
Applies to: ~>3.0
property FileSubType: DWORD;
For some file types this run time property provides additional information about the type of file. The information is that specified in the fixed file information part of the VERSIONINFO resource statement.
The value of this property is also provided by the the dwFileSubType member of the VS_FIXEDFILEINFO structure that is accessed using the FixedFileInfo property.
The value of FileSubType depends on the file type identified by the FileType property, as follows:
When FileType has value VFT_FONT (a font file) then valid values of FileSubType are:
| Flag | Description |
|---|---|
VFT2_UNKNOWN |
Font type is unknown. |
VFT2_FONT_RASTER |
A raster font. |
VFT2_FONT_VECTOR |
A vector font. |
VFT2_FONT_TRUETYPE |
A TrueType font. |
When FileType has value VFT_DRV (a device driver) then FileSubType can take one of the following values:
| Flag | Description |
|---|---|
VFT2_UNKNOWN |
Driver type is unknown. |
VFT2_DRV_PRINTER |
Printer driver. |
VFT2_DRV_KEYBOARD |
Keyboard driver. |
VFT2_DRV_LANGUAGE |
Language driver. |
VFT2_DRV_DISPLAY |
Display driver. |
VFT2_DRV_MOUSE |
Mouse driver. |
VFT2_DRV_NETWORK |
Network driver. |
VFT2_DRV_SYSTEM |
System driver. |
VFT2_DRV_INSTALLABLE |
Installable driver. |
VFT2_DRV_SOUND |
Sound driver. |
VFT2_DRV_COMM |
Communications driver. |
When FileType has value VFT_VXD (a virtual device driver) then FileSubType contains the virtual device identifier included in the virtual device control block.
In all other cases, including when there is no version information available, FileSubType contains no information and should be zero.
Constants for all the values discussed above are defined in the Windows unit.
