[MS-OXCFXICS] SendOptions flag values RRS feed

  • Question

  • [MS-OXCFXICS] v2.0 Section 2.2.3.1.1.1.2 "SendOptions" contains a table showing various values for the SendOptions field, used in the RopFastTransferSourceCopy* type ROPs. SendOptions is described as a set of flags.

    The ForUpload flag is shown with a value of 0x03. That seems a bit strange for a flag. Is this meant to be 0x02?

  • Turns out that ForUpload is actually a mask of Unicode (0x01) and UseCpid (0x02).   If you pass UseCpid (0x02) it must be OR'd with Unicode (0x02) which is the equivalent of ForUpload (0x03).  ForUpload = Unicode | UseCpid.

    I have filed a TDI against the documentation to add UseCpid and break out ForUpload from the table.

  • Hi Brad,

    In review of the code the values in the table are correct. Are you seeing something different?

  • Hi Tom,

    Haven't managed to test this one yet - just working on the IDL.

    My concern was that the SendOptions involves flags (i.e. this is not an enum, its a bitmask of values that can be ANDed together)
    0x01 (b00000001) is Unicode
    0x03 (b00000011) is ForUpload
    0x04 (b00000100) is RecoverMode
    0x08 (b00001000) is ForceUnicode
    0x10 (b00010000) is PartialItem

    That implies ForUpload forces Unicode, which is a strange requirement. I can understand a linkage between Unicode and ForceUnicode (as explained by the docs), but not that.

    So I'm still a bit curious. Are you sure about your code here?

  • The table is correct (triple checked) and as you pointed out there is an implied Unicode for ForUpload.  In general the shared masked bit it's handled by control flow but I did find one situation where there appears to be a hole.  Let me ask development for clarification on this one.

  • Tom,

    Thanks for following this up.

    I think I see a typo though "...it must be OR'd with Unicode (0x01 ) which is..."
