|---|---|
| PropertyTagTypeASCII | Specifies that the value data member is a null-terminated ASCII string.
If you set the type data member of a PropertyItem object to PropertyTagTypeASCII, set the length data member to the length of the string including the NULL terminator. For example, the string HELLO would have a length of 6. |
