I also doubt the timer would be affected - but its usefulness would depend on what the OP is trying to do.
If it's "do something approximately a day later", then SetTimer would be fine, or checking GetTickCount on a more rapid timer.
If it's "do something at the same time tomorrow, and the user will look at their clock and be puzzled why they started the program at 1pm and it's midday now..." then you need to do it a different way.
It really depends on what (s)he's trying to do.

Well, timers and alarms are pretty different things, I suppose the OP knows about. But this is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong. 
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Oh, don't bother too much. Sometimes I'm a bad guy really deserving downvoting.

Well, since the Elapse argument of the SetTimer can take a maximum of USER_TIMER_MAXIMUM (i.e. on my system, 0x7FFFFFFF milliseconds, that is about 25 days) I'm happy with it.
Moreover it isn't such a difficult task to make longer intervals using shorter ones.

I hear you. I can make small timers, kill them and do 'settimer' repeatedly, but then being a lazy programmer - was thinking of skipping them and just have a one-shot timer

Counting isn't an option for you, is it?

You can store datetime when application starts. Set some timer interval and read cureent time each time when receive WM_TIMER message. If the difference between application starting time and current time matches your requirement, take desired action.

I have a dialog based application.In this I have a button which takes the value in a textbox and adds it to a combobox.I have to enter values in three textboxes.All these values have to be written into a file.
I have writen the code as follows:
GetDlgItemText(IDC_EDIT1,str1);<br />
GetDlgItemText(IDC_EDIT1,str2);<br />
GetDlgItemText(IDC_EDIT1,str3);<br />
fstream f;<br />
f.open("myfile.txt",ios::in|ios::out);<br />
f.write(str1,str1.length());
When i open the file to view the contents,its not written properly.Also I want to append the details each time I enter values in the textboxes.

How str1, str2, str3 are declared.
What values were assigned to such variables?
What is written inside the file, insted?

You wrote only the first string. What isnt properly?
Read the docs to fstream. This is really beginners stuff.

try this
change the fopen as
f.open(myfile.txt",ios::in|ios::out|ios::app);

You better write "MSXML2.DOMDocument.2.0"
is MSXML4.dll correctly installed?
