Question

Hi i’m using VS2010 and MBCS. Can anyone tell me how to convert an unsigned char to LPCSTR? Sorry i’m only new to c++…:) Thanks

This is the code it is failing on:

    hr = MsiSetProperty(hInstall, "LOCKCODE",  szLockCode);
    ExitOnFailure(hr, "failed to set LOCKCODE");

szLockCode is the variable that needs to be converted.

An unsigned char array (unsigned char szLockCode[10] for instance) is technically already an LPCSTR. If you’re using an array already then conversion is not the issue, if not, then you need an array. If you want a single character string, then you need an array of length 2. The character goes in the first position (szLockCode[0]) and the value 0 goes in the second position (szLockCode[1]).
