Why is StringCbPrintf formattting wrongly?

VS2010

I have the following line of code in my program:

C++

StringCbPrintfA(szString,sizeof(szString),"INSERT INTO ClassRecord(SchInfoID,ArmNameID,ClassNameID,ClassTypeID,SessionID) VALUES(%u,%u,%u,%u,%u)",iSchInfoID,iArmNameID,iClassNameID,iClassTypeID,iSessionID);

where the relevant types are

C++

long long &iSchInfoID;

 long long iArmNameID, iClassNameID, iClassTypeID, iSessionID;

intellisence shows that:

C++

iSchInfoID 1
iArmNameID 1
iClassTypeID 1
iSessionID 1

But 0 is placed in the buffer for iArmNameID.

What could be wrong?

Your types are "long long" but the format specifier is "%u".

Try "%llu" for an unsigned 64 bit value.

I tried it.It successfully formatted the first three variable, but the remaining variable were rendered as a long unending string of numbers.

It is not compulsory that I make it unsigned. It is somehow compulsory that I make it 64 bit.
Please what is the format code for 64 bit integer? It is because I dont't really know it that I used that.

Previous to posting this question, I had tried, "%d" but got the same result.

I was finally able to fix it.The garbage that was previously produced was due to the fact that iClassTypeID was of type INT_PTR and i used llu for it.

Once again, thanks a lot.
