Re: How can I read individual bit values in a returned integer Jim Crafton12-Oct-01 14:17 Jim Crafton 12-Oct-01 14:17  An alternate solution that I have found useful when having to check a specific bit, like checking whether bit 29 in a 32 bit value is on or off, is using the std::bitset class. std::bitset<32> keyBits; if ( keyBits[29] == 1 ) { //bit 29 is set //do something } Linked List Math Functions jbiggs779-Oct-01 14:18 jbiggs77 9-Oct-01 14:18  I am trying to implement a linked list which will store large numbers(one digit in each node). I am not really familiar with the different math functions and was wondering what would be the easiest way to add and multiply some of these numbers. Thanks in advance for the help. Re: Linked List Math Functions Jonathan de Halleux31-Oct-01 2:48 Jonathan de Halleux 31-Oct-01 2:48  You mean big integers ? Knuth has written a lot of algorithms for these type of integers. In fact they are the kernels of RSA cryptographic algortihms. I don't know if there are available libraries but you should read the following book to understand the theory behing those numbers: "The art of computer programming. 2 : Seminumerical algorithms" / Donald E.

John Clump8-Oct-01 21:00 John Clump 8-Oct-01 21:00  Is there an existing class or library that allows your (MFC) app to work with file type associations? I know they are stored in the registry, but I am not quite sure how to properly set them, and have not been able to find documentation about this on MSDN. If there is not an existing class to do this, can someone explain how to set them directly in the registry? Or where I can find the information? check if connected to internet 8-Oct-01 15:32 8-Oct-01 15:32  hi all im using c++ and i need to check whether the computer is connected to the internet, without dialing to get the connection. i hope someone can help me dills Re: check if connected to internet Not Active11-Oct-01 2:25 Not Active 11-Oct-01 2:25  InternetCheckConnection(NULL, FLAG_ICC_FORCE_CONNECTION, 0) returns true if connection is available otherwise false. check if connected to internet 8-Oct-01 15:31 8-Oct-01 15:31  hi all im using c++ and i need to check whether the computer is connected to the internet, without dialing to get the connection. i hope some can help me dills OLE drag and drop using MFC vgandhi8-Oct-01 10:40 vgandhi 8-Oct-01 10:40  Hello, I am trying to implement a bar like the outlook bar and want to insert drag and drop functionality in that bar.

Re: How to close a file opened with CreateFile API Lim Bio Liong3-Dec-01 0:41 Lim Bio Liong 3-Dec-01 0:41  I assume you are developing in Win32. Use CloseHandle() to close the file. The following is taken from the Win32 documentation for CreateFile() : "Use the CloseHandle function to close an object handle returned by CreateFile." Note that it is very important to call CloseHandle(). Otherwise, the handle table of your application will continue to grow and you will run out of memory in the long term. After closing the handle, it is best to set the value of your handle variable to NULL so that you do not close the handle again. Closing a handle twice will raise an exception.

I've created a MFC application that is linked to OpenGL. How do I created functions like the ones we see in the "Paint" program found in windows accesories? For example, if I click on the menu which as a "draw lines" function and after clicking on that, I would like to use the mouse to draw lines, (line starts when the mouse is clicked and dragged. Then the line stops when mouse is released). I'm having great difficulty doing this and if anyone can help it would be greatly appreciated. Thank you in advance! Steve Re: Drawing lines with OpenGL(like the Paint program in windows) Jonathan de Halleux31-Oct-01 3:17 Jonathan de Halleux 31-Oct-01 3:17  1. Override OnLeftMouseDwn Store the position of the mouse when clicked, set a flag to tell that the left button is down, 2. Override OnMove Store the position of the actual position of the mouse, ask for redraw, (InvalidateRect(NULL,FALSE); 3. In OnDraw, check if left button is down, if so, draw a line from initial position to actual position, 4. Override OnLeftMouseUp, unset the flag. This is the basic idea, of course you can refine the concept. Jonathan de Halleux, Belgium.
