I don't know of a way, but I'm curious why you'd need this type of information.

Yes, but only if there was a benefit in knowing such information. Since the display adapter does not care whether the monitor is actually on or off, finding a straight-forward API to tell such information is going to be hard to find, if at all.

I doubt that there is a way to detect this. How would you determine the difference between the monitor being without power and the monitor not being connected at all.

With regards to standby. This is governed by power management. I personally have no experience of power management on windows and therefore do not know any API calls that could be made. I would have thought that these do exist however.

Correct, a plug and play monitor can give you some info. (I'm not sure how much), but many monitors are not plug and play. If you stick to new machines this is unlikely to be a problem, but as soon as your software hits any test lab I've been in, most of the monitors it deals with will not be plug and play.

How about running them when the screen saver is active?
You can detect if screen saver is active, and I think, event set your app up to be notified when it has gone active.

Running a program when screen saver is active , doesn't mean knowing monitor status(An what happend if screen saver is disable ? Smile | :)

).

However its one option..

Now i am looking it to PowerManagment & hopes get some way to it ..

Hello,

I want to check whether an IP address i alive or not .. like the ping... i m using GetRRTandHopCount() method to determine whether the IP address i m sending to this function is alive.. in case it get the response it return true otherwise false. now probelm is that if the IPAddress dont exist in LAN it return false very quickly.. and if it is alive it gave a quick response.. but if an IPAddress falls in the range of that is allocated to lan then this function respond very slowly...

is there any way to improve the response time or someother function that can be used for this purpose

Why not actually do a ping (ICMP echo)?

You could then use IcmpSendEcho() which has a timeout in milliseconds that can be set.

See the IP Helper Reference[^] for the other Icmp Echo functions.

This might have been a viable solution 3+ years ago, but servers of late have turned off PING replies. So even though you PING a valid, working server, if the server has PING replies turned off, you'll get no reply, making it look like an invalid address.

i used the that function and it gives me error

the procedure entry poingt createfile could not found in the dynamic link libaray iniphlpapi.dll...

Plzzz suggest some solution soon Cry | :((

Antony M Kancidrowski17-Aug-04 2:56

Without seeing your code it is hard to say what the problem is.

Ensure you have included these headers

#include "iphlpapi.h"
#include "winsock2.h"
#include "icmpapi.h"

and you are linking to these libraries

icmp.lib
Ws2_32.lib

NOTE: You need the winsock2 stuff if you use inet_addr() to generate the destination address.

Hi,
Is there ate any alternate option available instead of STL List. I have created template class, also tried with Linked List. But it's search option is very slow. Let me know good suggestion from you.

Have you tried any of the other STL container classes, I think a set should give you faster lookup times.

std::map - when doing lookups
std::vector - could be used if you are using fixed index
