the buffer remains blank although the string array element has data in it ....

char copyToBuf[128]={0};<br />
strcpy(copyToBuf, openDoorTags[0].c_str());

all the strings in your array are empty, so it's normal that the buffer will be empty too

The only programmers that are better that C programmers are those who code in 1's and 0's

cout << openDoorTags[0].c_str();
