how avoid  the writing of another price data  over the one price data?
why happen this instance?

const a_psDataRec


If you want people to help you with your coding, please post the code!

            invoke MSFL1_WriteDataRec,hSecurity,addr psPriceRec,1
            invoke MSFL1_UnlockSecurity,hSecurity

Nothing in the code immediately strikes me as being an obvious cause of the problem (I have had a few glasses of wine after a long day, so my reading of ASM might be a little fuzzy), except that your previous posts on the Forum have all been concerning writing data with the MDK and I believe you only have the Read version?

If you explained in detail what you are trying to achieve with these continuous attempts to write data, perhaps we might have a better solution to offer?

With thanks to Neale who pointed this post out to me again....

"invoke MSFL1_WriteDataRec,hSecurity,addr psPriceRec,1"

MSFL1_WriteDataRec(HSECURITY hSecurity, const MSFLPriceRecord_struct *psPriceRec,)
vs.
MSFL2_WriteDataRec(HSECURITY hSecurity, const MSFLPriceRecord_struct *psPriceRec, BOOL Overwrite)

MSFL2 has three arguments, the third is overwrite.


Hope this helps.

thanks my brother but i detach the problem. the problem is false function use. i use MSFL1_InsertDataRec instead of  MSFL1_WriteDataRec.
