Hi:
This is a bug in VfrCompile. It doesn't support to specify VarId for
NameValue storage. We will fix it.
If one of question is related to NameValue storage, HiiCreateOneOfOpCode()
can be used like below. It will use VarOffset field as VarName for NameValue
storage.
HiiCreateOneOfOpCode (
StartOpCodeHandle, // Handle to the buffer of opcodes
KEY_Q1, // Question ID
StorageId, // Storage ID
STRING_TOKEN (STR_VALUE1), // VarName or 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
);
Thanks
Liming

Hi Neeraj,
Thanks for your comment, but my one-of-list is entire generated dynamically and
could not be predefined.
Hi Galla,
This is strange. I'm using UDK2010 also and just have tried it again, the
VfrCompile always reports an ERROR 12288: varid : unexpected token
Here is my code in VFR, mind if you give it a try in your build?
namevaluevarstore NameValueVar1,
varid = VAR_NEW_ID, <------ VfrCompiler breaks here: ERROR 12288: varid
: unexpected token
name = STRING_TOKEN(STR_VALUE1),
name = STRING_TOKEN(STR_VALUE2),
guid = ABC_FORMSET_GUID;
If you are sure it can pass, I wonder if I'm using an outdated VfrCompiler,
mine is version 2.00 Build 2524 (7/15/2011). What is yours?
Thanks,
Simon

Simon,
if your data values are predefined, you can create them in formset and hide
them using supressif upon a condition.

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

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
