Hi All, I have uploaded the third version of the example on my site. it can be reached via the following page: https://www.jahanshahi.ws/owl.htm and the link following link: https://www.jahanshahi.ws/sources/WN_NC_DEMO.rar Mohsen

Hi Thien, I am sorry for late answer and for the inconvenience regarding my site. I have transferred it to another server and perhaps that is the reason for the problem. I have attached the example here. Sebastain has provided a newer version bellow. Mohsen

Hi Vidar, Principally, I am talking about screen redraws. For example, when we want to pan the window or zoom part of the screen. In the former case, we need to redraw the whole model. Using TMemoryDC combined with BitBlt helps to refresh screen faster than redrawing the whole model each time it is needed. However, for me panning the window using this approach causes another problem. Redrawing becomes so fast that I do not see anything when I move the mouse fast. I need to move it slowly so that...

Hi All, For those who are interested, the following examples present an efficient way for using TMemoryDC to accelerate screen redraws using GDI: BC5\EXAMPLES\APPS\MTHREAD and BC5\EXAMPLES\APPS\GDIDEMO Mohsen

Thank you Vidar. Yes, I remember from the old owl code that a similar function existed and it was ScreenToClient. I was searching the source code for ScreenToWindow! By the way, do you suggest any TMemoryDC example for accelerating screen redraws using GDI? Mohsen

Hi All, I was trying to handle the WM_MOUSEWHEEL event through EvMouseWheel. I wanted to convert the coordinates of mouse from screen to the client window. I am using the WIN API ScreenToWindow function. I was wondering if an equivalent exists in OWLNext. Thanks, Mohsen

Hi All, The example is available on my OWL page which can be accessed using the following link: http://www.jahanshahi.ws/owl.htm Thanks, Mohsen
