I am stuck on these C++ data types const wchar_t * since last week.
It worked well in C# console application under mentioned below

Hi TRScheel,

Thank you your prompt reply and
I am planning on running in native C++ using VS 2008 and integrate with
The sizeof(char) on your system is 1 byte and I couldn't well where I put these lines in my coding.
[k*colorBmHeight + i*3]
The image size is let say 1976 x 1472
Calculate the number of bytes in a row. Something like:

KYAW KYAW OO replied to How to extract RGB as unsigned char * from unsigned char * of 24 bit BMP Color imagesin CHi,
Thanks for your prompt reply. As for me, I would like to extract out red, green, blue, unused as each unsigned char * since my dll based on native C or C++ only. As well, the other SDK only accept as I mentioned R,G,B differently then combine as one color byte. Please advise me and looking forward to hearing from you soon.
