From reading the documentation, all it means is that to align "Inset", you have to draw something that has an inside and an outside. It seems to me that rects and elipses should work fine with that alignment.

Unfortunately, the dots and dashes are disfigured blobs with inset. It's not nearly as noticeable with Ellipse and dash since one of the distortions is a kind've curving and it happens to distort in the same direction as the curve. However, an Ellipse with dot exhibits the distortion in a very obvious way.
With rects, it's easy to identify with dashes or dots.





can anyone tell about the difference between rs232 and rs422 in detail please..
thanks in advance
regards
sudhakar





RS422 uses differential signaling so one is not dependent on a common earth. It makes the signal less sensitive to noice and capacitance and inductivity problems which allow for higher baudrates. I don't know the exakt charachterisitcs of the signal that's being sent.






Hi,
How to calculate Months & Days difference between given two dates? Is there function like DateDiff in C++?
Thanks in Advance,
R

From MSDN 
To calculate elapsed time
Use the CTime and CTimeSpan objects to calculate the elapsed time, as follows:
CTime startTime = CTime::GetCurrentTime();
// ... perform timeconsuming task ...
CTime endTime = CTime::GetCurrentTime();
CTimeSpan elapsedTime = endTime  startTime;
Once you have calculated elapsedTime, you can use the member functions of CTimeSpan to extract the components of the elapsedtime value.





COleDateTime::operator +, 
This might be useful.
Disclaimer: I've never used it but it appears to claim to do what your asking.





dear profesional over here...please help me with this problem,i have been trying to solve this problem for pass few hours..and i am still a beginner but the task given to me was too tough for me..
this program has 3 errors..i am halfway stuck please help me..
below is da task given to me..please help and do explain me my mistake.
i want to improve..
Create several files of integers to be used to test sorting methods. Make files of several sizes, for example, size 20, 200, and 2000. Make files that are in order, in reverse order, in random order, and partially in order. By keeping all this test data in files (rather than generating it with random numbers each time the program is run), the same data can be used to test different sorting methods, and hence it will be easier to compare their performance.
Write a menudriven program for testing various sorting methods. One option is to read a file of integers into a list. Other options will be to run one of various sorting methods on the list, to print the unsorted or the sorted list, and to quit. After the list is sorted and (optionally) printed, it should be discarded so that testing a later testing method will start with the same input data. Write the program such that each new sorting method will process the original input file.
Include code in the program to calculate and print
a. CPU time
b. The number of comparisons of keys.
c. The number of assignments of list entries during sorting a list.
Counting comparisons and assignments requires setting up global variables and inserting code into each sorting procedure to increment one of these global variables each time a key comparison and entry assignment is made.

Can you ask your teacher not to give out this forum's URL as a training assistant?
Homework questions are there to test knowledge you should already have been given in your class.

So why not do the logical thing and start with a less ambitious project? Sorting data structures is not a beginner's project.

I recommend finding a copy of “Algorithms in C” by Robert Sedgewick, usually easier to understand than Knuth’s books, or just search the Web.
You have a lot to learn, passing the size of a global array makes no sense because it will lead to errors; if the array is global then the variable, or “#define” statement, telling you the size, should also be global.
Simplify: Start small by writing code that does not require external files, say a few arrays of integers. That way any good debugger will show you what is happening (single stepping). Then work your way up, one step at a time. Believe it or not, but that is how a lot of us solve these types of problems.

You can also respond to the WM_CTLCOLORSTATIC message in the parent window
and set the control's color(s) ...
ON_MESSAGE(WM_CTLCOLORSTATIC, OnCtlColorStatic)
...
RedBrush.CreateSolidBrush(RGB(0xFF,0x00,0x00));
...
LRESULT CMMyDlg::OnCtlColorStatic( WPARAM wParam, LPARAM lParam)
{
HDC hDC = (HDC)wParam;
HWND hWnd = (HWND)lParam;
if (IDC_MYSTATIC == ::GetWindowLong(hWnd, GWL_ID))
{
::SetTextColor(hDC, RGB(0x00,0xFF,0xFF));
::SetBkColor(hDC, RGB(0xFF,0x00,0x00));

return Default();

I have some ATL Composite control that i wrote  this Control "site" in some dialog.
I want to throw some event from this Control into the dialog  how can i do it ?
Thanks.

Some platforms, including MFC and VB6 provide easy support for receiving control events in a dialog. If you aren't using one, or are using the control in a way that the platform doesn't support, you'll need to implement the control's event sink interface, and register it with the controls connection points when you create the control, and unregister it before destroying the control. You can look up info on IConnectionPointContainer and IConnectionPoint for more info on this.
