problem with strings greater then 32ks

safee ullah

hello there .. there is a slight problem that i am facing with strings greater then 32k i have a variant bstr containing a string which is greater then 32ks.. 1. how do i store this thing? into a buffer?, but then how do i get the size of the bstr string so that i can create a buf of that size? 2. how do i truncate this bstr string into strings of sizes 32ks? thanks for the time regards

Why are you wanting to store something that is already stored? If the bstr variable already holds the data, why are you wanting to create another variable to hold that same data?

Something like this, maybe:

BSTR    b = SysAllocString(\_T("This is a 32k string"));
TCHAR   left\[11\],
        right\[11\];

\_tcsncpy(left, b, 10);
left\[10\] = '\\0';
\_tcsncpy(right, b + 10, 10);
right\[10\] = '\\0';

beter to store that much in file..... read from a file.
