/* character string to be updated */

Gets the text (character string) of the annotation object. This function is available in the Document/Medical Toolkits.

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.

GetText can be used to retreive text that was set using LAnnRTF::SetTextRTF, but no formatting information will be preserved. To retrieve the text with formatting, use LAnnRTF::GetTextRTF.

Example

void TestModifyAnn(LAnnRTF L_FAR * pAnnObject)
{
   L_TCHAR L_FAR * pText; /* The object’s text */
   HGLOBAL hText; /* Handle for memory management */
   L_UINT TextLength; /* Length of the object’s text */

   /* Get the length of the current text */
   TextLength = pAnnObject->GetTextLen();
   /* Add six characters to the length for our new text */
   TextLength += 6;

    /* Allocate and lock a zero-filled buffer for the text */
   hText = GlobalAlloc(GPTR,TextLength * sizeof(L_TCHAR));
   pText = (L_TCHAR L_FAR *)GlobalLock( hText );
   /* Get the current text */
   pAnnObject->GetText(pText);
   /* Add " - New" to the end of the current text */
   lstrcat(pText,TEXT(" - New"));
   pAnnObject->SetText(pText, 0);

   /* Free memory that we no longer need */
   GlobalFree(hText);
