sorry, bad structure, this is are bit easier to read... (I hope)

void *GetObjectPtr(UInt16 ownerForm, UInt16 fieldName)
{
    return FrmGetObjectPtr(FrmGetFormPtr(ownerForm),
            FrmGetObjectIndex(FrmGetFormPtr(ownerForm),fieldName));
}

void SetEditText(UInt16 ownerForm, UInt16 fieldName,Char *text)
{
    FieldPtr THIS = GetObjectPtr(ownerForm, fieldName);
    MemHandle h,old;
    Char *dest;
    if( text == NULL )
        text = "";
    h = MemHandleNew( StrLen( text ) + 1 );
    dest = MemHandleLock( h );
    StrCopy( dest, text );
    MemHandleUnlock( h );
    old = FldGetTextHandle( THIS );
    FldSetTextHandle( THIS, h );
    if( old != NULL )
        MemHandleFree( old );
    FldDrawField(THIS);
}

Char* GetEditText(FieldPtr THIS)
{
    Char *text;
    text=FldGetTextPtr(THIS);
    if (!text)
        text="";
    return text;
}
