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.

L_INT LAnnButton_GetTextExample(LAnnButton  * pAnnObject) 
{ 
   L_INT nRet; 
   L_TCHAR  *pText; /* The object's text */ 
   L_SIZE_T TextLength; /* Length of the object's text */ 
 
   LBuffer LeadBuffer; 
 
   /* Get the length of the current text */ 
 
   TextLength = pAnnObject->GetTextLen(); 
 
   /* Add six characters to the length for our new text */ 
 
   TextLength += 6; 
 
   LeadBuffer.Reallocate((DWORD)TextLength*sizeof(L_TCHAR)); 
 
   pText = (L_TCHAR  *)LeadBuffer.Lock(); 
 
   /* Get the current text */ 
 
   nRet = pAnnObject->GetText(pText,&TextLength); 
   if(nRet != SUCCESS) 
      return nRet; 
 
   /* Add " - New" to the end of the current text */ 
 
   lstrcat(pText,TEXT(" - New")); 
 
   nRet = pAnnObject->SetText(pText, 0); 
   if(nRet != SUCCESS) 
      return nRet; 
 
   LeadBuffer.Unlock() ;
