I have create some dynamic CEdit controls..

e.g...

CEdit newEdit; // as a member var of class in the header

newEdit.Create(WS_VISIBLE|ES_NUMBER|WS_DLGFRAME ,startRect,this,NULL);

...

What window style flags do I need to set so the CEdit looks like a standard CEdit that you get when adding to a dialog resource?

Thanks in advance

Hi, how can I identify a carriage return (\n)using fscanf ?
Thanks,

Deepak Samuel.

It has an ascii value of decimal 13, eg.

if(nChar==13)AfxMessageBox("Carriage Return");

I am scanning the file for interger values what happens if my file itself contains a integer value of 13 ? How can I differentiate between my data and a carriage return?`
Thanks,

Deepak Samuel

Maybe you can tell by looking for CR, LF...at the end of each line.

Character 13 and number 13 are totally different things. When using fscanf(), you must tell it what type of data is being read. In other words:

char c;
fscanf(pFile, "%c", &c);

This will not read the number 13 from the file. Likewise:

int n;
fscanf(pFile, "%d", &n);

This will not read the character 13 from the file.

Make sense?

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.
