Something like: int nHex = 0x12345; char szBinary[64]; memset(szBinary, '0', sizeof(szBinary)); for (int x = 0; x < 32; x++) { if (nHex & 1) = '1'; nHex >>= 1; } strrev(szBinary); "Approved Workmen Are Not Ashamed" - 2 Timothy 2:15 "Judge not by the eye but by the heart." - Native American Proverb

In addition you also have to set the entry point symbol to wWinMainCRTStartup. This can be done in the Project->Settings menu->Link tab->Output Category->Entry-point symbol. Also IMO, one is better off using the TCHAR macros rather then hard coding the unicode functions and string literals.
