CHARTEVENT_OBJECT_CREATE does not react when an object is drawn

[Marbo]

Hello guys,

I am very confused. Why does this code not work if I press 'Q' but it works when I draw any object manually?

void OnChartEvent(const int id,
                  const long &lparam,
                  const double &dparam,
                  const string &sparam)
  {
//---
   ChartSetInteger(0, CHART_EVENT_OBJECT_CREATE, true);
   if (id==CHARTEVENT_KEYDOWN) {
      if (lparam=='Q') {
         ObjectCreate(0, "test", OBJ_VLINE, 0, Time[1], 0);
      }
   }
   else if (id==CHARTEVENT_OBJECT_CREATE) {
      Alert(sparam);
   }
}

Instead of: 

      if (lparam=='Q') {

have this:

      if (TranslateKey((int)lparam)=='Q') {

have this:

Unfortunately, that doesn't work. Now the vertical line is only printed when I press SHIFT and Q. But there is still no reaction from CHARTEVENT_OBJECT_CREATE.

I tested, it worked perfectly.

Check your code, especially the { and }. Post your latest version here if you still can't figure out.

I don't think that the problem is the TranslateKey()-issue because the key press itself works fine. The vertical line is printed every time. But the problem is that the ObjectCreate() doesn't send a message and the CHARTEVENT_OBJECT_CREATE is not triggered. But when I draw an object manually it works. It must have something to do with ObjectCreate(). But I have no idea why CHARTEVENT_OBJECT_CREATE does not react although a line is printed.

This is my code:
