Re: [Quickfix-developers] Checksum problem

[Dave L. <dav...@ma...>]

Hi Sangram,

It sounds like it is complaining about the BodyLength (tag 9) rather
than the Checksum. Is it possible for you to provide an example of the
failed message?

Cheers
Dave

Subject: [Quickfix-developers] Checksum problem


Hi All, 
I am using C++ for QuickFix application. I am having messages in string
format and constructing a fix message out of that. I am calculating the
checksum (field 10) for the message. Checksum is calculated properly for
all the messages expect the messages having field 310 or 210. Quickfix
throws exception saying
Invalid message: Expected BodyLength=xxx, Recieved BodyLength=yyy 
Here is the function to generate a checksum. 
char* generateCheckSum (const char* buf, long bufLen) 
{ 
    static char tmpBuf [4]; 
    long idx; 
    unsigned int cks; 
    for (idx = 0L, cks=0; idx < bufLen; cks+=(unsigned int) buf [idx++
]); 
    sprintf (tmpBuf, "%03d",(unsigned int) ((cks % 256))); 
    return (tmpBuf); 
} 


Any guess/help will be appreciated. 
Thanks & Regards, 
Sangram
