This function loads a string resource identified by the idString and the Resource parameters into the pszBuffer parameter, and appends a terminating null character.
RT_STRING resources (string resources) contain up to 16 strings each The resource ID is calculated from the idString passed to this function as follows:
resource ID = (idString / 16) + 1
To save storage on disk and in memory, applications should number their string resources sequentially, starting at some multiple of 16.
