Download and compile a VNC server source code. Locate the part of the code that receives rfbPointerEvent event from a client Add code to the server that would log rfbPointerEvent messages. You can do simple OutputDebugString to a debug console. With this information you should have pretty clear idea what messages a server expects to receive for the drag and drop to work.

It seems that your function "SendMousePointerEvent" sends "Mouse Button Up" event every time it is called, so it is physicly impossible to make drag event with the activeX api. Could you confirm this theory? Thank you. Tags Api

Have you tried to feed the same intput parameters to the SendMousePointerEvent? It seems that your function "SendMousePointerEvent" sends "Mouse Button Up" event every time it is called, so it is physicly impossible to make drag event with the activeX api. That's not correct. SendMousePointerEvent simply creates an RFB message with the arguments provided. It doesn't modify them in any way. Regards, Yury Averkiev, SmartCode
