But the problem is that the namevaluevarstore syntax does not support varid.
Please refer VFR Programming Language Spec Ver 1.7.

Subject: Re: [edk2] How to specify name/value storage in HiiCreateOneOfOpCode?
3rd paramter is VarStore ID it should be CONFIGURATION_VARSTORE_ID not
STRING_TOKEN
IN EFI_VARSTORE_ID VarStoreId,
you need to define it in yout VFR file. you can check sample code in UDK2010
varstore ISCSI_CONFIG_IFR_NVDATA,
varid = CONFIGURATION_VARSTORE_ID,
name = ISCSI_CONFIG_IFR_NVDATA,
guid = ISCSI_CONFIG_GUID;

Suppose a name/value storage has been defined in VFR file like below:
//
// Define a name/value storage (EFI_IFR_VARSTORE_NAME_VALUE)
//
namevaluevarstore NameValueVar1,
name = STRING_TOKEN(STR_VALUE1),
name = STRING_TOKEN(STR_VALUE2),
guid = ABC_FORMSET_GUID;
Now to create a one-of drop down menu list dynamically, I need to invoke
HiiCreateOneOfOpCode in the callback function of HiiConfigAccess. However
how should I set the Storage ID to the name/value storage NameValueVar1 in the
function? Following is what it looks like (note namevaluevarstore
does not support varid descriptor in VFR):
HiiCreateOneOfOpCode (
StartOpCodeHandle, // Handle to the buffer of opcodes
KEY_Q1, // Question ID
STRING_TOKEN (STR_VALUE1), // <===== incorrect Storage ID?
0, // Offset in storage
STRING_TOKEN (STR_XXX_PROMPT), // String ID for prompt
STRING_TOKEN (STR_XXX_HELP), // String ID for help
EFI_IFR_FLAG_CALLBACK, // Flags in Question header
EFI_IFR_TYPE_NUM_SIZE_8, // Flags for oneof opcode
OptionsOpCodeHandle, // ONE_OF_OPTION opcode handle
NULL // Default opcode handle, OPTIONAL
);
Tried all different ways without success. Any comments/hints would be greatly
appreciated.
Thanks,
Simon
