Guid - generate, convert(string to struct / struct to string
Posted: 07 May 2015, 09:16
Simple lib to manage creation and conversion(to/from string) of GUID/CLSID. Related: jNizM's Class & Func GUID / UUID
Create/generate GUID:
oGuid := Guid_New()
Create/generate GUID:
oGuid := Guid_New()
- To retrieve the address of the GUID structure:
pGuid := oGuid.Ptr OR pGuid := oGuid[] - To retrieve the string representation of the GUID:
sGuid := oGuid.Str
- String to GUID struct:
pGuid := Guid_FromStr( sGuid, ByRef VarOrAddress ) - GUID struct to string:
sGuid := Guid_ToStr( ByRef VarOrAddress )
Code: Select all
Guid_New()
{
return new __GUID
}
Guid_FromStr(sGuid, ByRef VarOrAddress)
{
if IsByRef(VarOrAddress) && (VarSetCapacity(VarOrAddress) < 16)
VarSetCapacity(VarOrAddress, 16) ; adjust capacity
pGuid := IsByRef(VarOrAddress) ? &VarOrAddress : VarOrAddress
if ( DllCall("ole32\CLSIDFromString", "WStr", sGuid, "Ptr", pGuid) < 0 )
throw Exception("Invalid GUID", -1, sGuid)
return pGuid ; return address of GUID struct
}
Guid_ToStr(ByRef VarOrAddress)
{
pGuid := IsByRef(VarOrAddress) ? &VarOrAddress : VarOrAddress
VarSetCapacity(sGuid, 78) ; (38 + 1) * 2
if !DllCall("ole32\StringFromGUID2", "Ptr", pGuid, "Ptr", &sGuid, "Int", 39)
throw Exception("Invalid GUID", -1, Format("<at {1:p}>", pGuid))
return StrGet(&sGuid, "UTF-16")
}
class __GUID ; naming convention to avoid possible variable name conflict (global namespace)
{
__Get(key:="", args*)
{
if (key == "") || (key = "Ptr") || (key = "Str")
{
if !pGuid := ObjGetAddress(this, "_GUID")
{
ObjSetCapacity(this, "_GUID", 94) ; 16 + (39 * 2)
pGuid := ObjGetAddress(this, "_GUID")
if ( DllCall("ole32\CoCreateGuid", "Ptr", pGuid) != 0 )
throw Exception("Failed to create GUID", -1, Format("<at {1:p}>", pGuid))
DllCall("ole32\StringFromGUID2", "Ptr", pGuid, "Ptr", pGuid + 16, "Int", 39)
}
return InStr("Ptr", key) ? pGuid : StrGet(pGuid + 16, "UTF-16")
}
}
}
)
. Then I needed something that would allow me to retrieve the struct as well (
