Hi there.

I want to learn Multithreading programming in C++, Can some one please suggest good articles for the same.
Just FYI, I am well versed with VC++ but want to use only C++ for a specific purpose.

Thanks

There is a List of 25 primes declared in order and the above colors.

RED = 0X1000;
GREEN = 0x2000;
BLUE = 0x4000;
BLACK = 0x8000;
for ( i = 0; i < 4; i++, Color >>= 1 )
     for ( j = 0; j < 25; j++, n++ )
	Test[n] = primes[j] | (j << 8) | Color | (1 << (16+j));
<

primes[j] this is using one of the 25 whats in primes in order based on J.

Please what is this doing " | (j << 8) | Color | (1 << (16+j))" Can anyone help.

I know the logic works. But I can't understand what this is doing in the above loop.

Can someone please explain.

Thanks A million

it is time to pick up a book and learn about shift operators. It is the basics of programming. Look for LEFT SHIFT , RIGHT SHIFT , BIT WISE OPERATION...

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

MAPI problem under Vista

Hi to all.
I wrote an application which extracts information from contacts in outlook(name,e-mail,different phone and fax numbers and etc.). Everything works fine under winXP, but when installed on Win Vista machine application doesn't show any contact information from Outlook 2003 also on same machine!?
Furthermore there is no error reported from my app, so no issues with MAPI Initialization or retrieving MAPI profiles. It appears like nothing is found?
I'm thinking it can be an Vista issue, I tried with MFCMapi.exe but it couldn't find anything also.
Thanks

hallo,

i have SDI application, which is divided in two parts by CSplitterWnd object, i use CEditView instead of CView, when i type a text in the upper part and click on a button this text appears in the lower part, when i add a new text in the upper part and click the same button, the new text override the old text output(i use SetWindowTexW() and it overrides everytime the old output text) which i need is to keep the old text and the new one. i add the text everytime in an array and when trying to print out its content the above problem happens.

any idea / help to fix this problem will be appriciated.

CString csText;
GetWindowText(csText);
SetWidnowText( csText+csNewString);

You should have used "\r\n" instead.

Nope, you have to explicitely parse the returned buffer to extract them.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
