Hi everyone,
I was wondering how it is possible to modify the value of a field displayed in
an HII form.
For instance:
numeric varid = MyIfrNVData.HowOldAreYouInYears,
questionid = 0x1200,
prompt = STRING_TOKEN(STR_NUMERIC_STEP_PROMPT),
help = STRING_TOKEN(STR_NUMERIC_STEP _HELP),
flags = NUMERIC_SIZE_1 | DISPLAY_UINT_DEC | INTERACTIVE,
minimum = 0,
maximum = 243,
default = 0,
endnumeric;
In ConfigAccessProtocol DriverCallback, I have tried modifying this value in
certain places, with no success.
For instance on actions of type EFI_BROWSER_ACTION_FORM_OPEN and
EFI_BROWSER_ACTION_RETRIEVE I have tried accessing the Value union and changing
it: Value->u8 = 5
Then returning EFI_SUCCESS.
I have not seen any values being changed in all my tests. Is there a different
way to update the value?
Also, will updating the selected option in a 'one of' statement be similar?
Thanks in advance, Ben.
