Comments
Before calling this function, you must declare a variable as a pointer to a character string. Then, pass the variable in the pText parameter. This function will update the variable with the annotation object's character string.
The LAnnButton class gets and sets text without formatting. Use the LAnnRTF class to use formatted text.

/* Add six characters to the length for our new text */
TextLength += 6;
LeadBuffer.Reallocate((DWORD)TextLength*sizeof(L_TCHAR));
