How to Manage Multi Monitor IDs in C++ rewantlge 10/14/2008 7:05:00 AM Iam Developing a Multi monitor Application in C++ MFC VC 6.0 in which i need to manage the diffrent monitor IDs for eg if 6 monitors are connected windows will assign IDs as 1,2,3......6 to the monitors and it can be verified->with the help of Desktop->Properties->Settings->Right Click on Monitor which u want to Identify and click on identify it will display the assigned number on the monitor.This is the normal way of identifying the monitor . Now my problem is i need to change these system assigned IDs and change the Numbers according to USER flexibility for eg if the window assigns number 6 to the monitor just right to him and he needs to change it to say 2, he should be able to do that ..ie changing the syem assigned IDs of monitors without reconnecting them or swapping of the monitor IDs so that he can play with the applications running on the primary monitor and shift them to the respective Monitors. -- rewant

I fail to see how this can be even remotely related to the WindowsMedia SDK. In any case, I don't think there is any user-mode API to change the display number since it depends on the way the kernel drivers enumerate the devices and it wouldn't be a good idea because an application should not have system-wide effects. Since the number is shown by your application GUI, just remap the user-chosen IDs to the actual system IDs in your own code. -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm
