Access-Violation with AdvDateTimePicker

VCL TMS VCL UI Pack

Hi,

I get an Acess-Violation with the DateTimePicker.
I can reproduce the error, when put the DateTimePicker at a frame and call a window with the frame from mainform.
I can stop this error by insert a "if (frm = nil) then Exit;" in the "UpdateTimePicker".

I change it to:

    if not FTimePicker.Visible and (not (csLoading in ComponentState) or (csDesigning in ComponentState)) then
    begin
      FTimePicker.Free;
      FTimePicker := nil;
    end
    else
    begin
      frm := GetParentForm(Self);
      if (frm = nil) then
      Begin
        Exit;
      End;

      DropW := Round(DROPDOWNBTN_WIDTH * GetDeviceCaps(frm.Canvas.Handle, LOGPIXELSY) / 96);


and can remove this error. I don't know if this is the right way, so please check if this change is meaningful. I hope you can reproduce this error or at least can find a way to stop this error for me.

Thanks for reading so far.

We had seen this problem already and had internally fixed this already. It is specific to use of the component on a frame. The next update of TAdvDateTimePicker will address this.
