Use these two...I got them from one of my Codewarrior Companion Reference
books.
Here's an example of a call:
SetFieldTextFromStr( MyFieldID, MyStrP );
-Rus
static FieldPtr SetFieldTextFromHandle( Word fieldID, Handle txtH )
{
Handle oldTxtH;
FormPtr frm = FrmGetActiveForm( );
FieldPtr fldP;
// Get field and field's current text handle
fldP = FrmGetObjectPtr( frm, FrmGetObjectIndex( frm, fieldID ) );
ErrNonFatalDisplayIf( !fldP, "missing field" );
oldTxtH = FldGetTextHandle( fldP );
FldSetTextHandle( fldP, txtH );
FldDrawField(fldP);
if ( oldTxtH )
MemHandleFree( oldTxtH );
return fldP;
}
static FieldPtr SetFieldTextFromStr( Word fieldID, CharPtr strP )
{
Handle txtH; // Sets up a string handle from str and calls
txtH = MemHandleNew( StrLen( strP ) + 1 ); // SetFieldTextFromHandle
if ( !txtH )
return NULL;
StrCopy( MemHandleLock( txtH ), strP );
MemHandleUnlock( txtH );
return SetFieldTextFromHandle( fieldID, txtH );
}
