what this does Ahmad31-Jan-01 23:20 Ahmad 31-Jan-01 23:20  HI ALL My question about HIWORD and LOWORD ? I'm always see LOWORD (wParam) // in WndProc function some Data Types like WPARAM , LPARAM ,DWORD have LOWORD and HIWORD value I found in MSDN about HIWORD and LOWORD it tell me it's macros like #define HIWORD(l) ((WORD) (((DWORD) (l) >> 16) & 0xFFFF)) #define LOWORD(l) ((WORD) (l)) but I can't understand what this mean and what this does can you tell me please ... Re: what this does .::RockNix::.31-Jan-01 23:40 .::RockNix::. 31-Jan-01 23:40  Thats simple: usually u use a command like (HIWORD)(lParam) ! That means you want to have the upper 16 Bit from 32. To get them you have to shift right 16 (>>16) times and mask out the upper 16 Bit ( & 0x0000ffff ). To get (LOWORD)(lParam) you have to clear the upper 16 Bit. Converting to a new type WORD from DWORD takes only the lower 16 Bit. The effect is the same.

Re: Mail protocols Erik Funkenbusch1-Feb-01 15:38 Erik Funkenbusch 1-Feb-01 15:38  POP3 is actually quite easy. You just connect a socket and send some text commands, then retrieve the returned text. Check out www.rfc.net for the actual specifications. Converting integers from array to integer variables Mike Zolna31-Jan-01 19:01 Mike Zolna 31-Jan-01 19:01  I have an array of numbers say array[0]=-10, and array[1]=23. Furthermore, lets say that they represent a most significant bit, and a least significant bit, so in reality the number is -1023. How do I combine both elements of the array into a signed integer that I can store?? Regards Mike Zolna Re: Converting integers from array to integer variables Michael Dunn31-Jan-01 19:35 Michael Dunn 31-Jan-01 19:35  Using your simple example, int number = array[0]*100 + array[1]; --Mike-- http://home.inreach.com/mdunn/ Time is an illusion; lunchtime doubly so. Re: Converting integers from array to integer variables Mike Zolna31-Jan-01 19:39 Mike Zolna 31-Jan-01 19:39  Thanks, but what if the number is 102 and not 1023, that wont work. I dont know that magnitude of the numbers until they are joined together Mike Re: Converting integers from array to integer variables Michael Dunn31-Jan-01 19:45 Michael Dunn 31-Jan-01 19:45  I don't know what your program is like, so it's hard to say. But if you don't know what the final result should look like, then you won't be able to calculate the final result. You'll need some sort of separate indicator to tell you how the result is split up among the array elements. --Mike-- http://home.inreach.com/mdunn/ Time is an illusion; lunchtime doubly so. Re: Converting integers from array to integer variables Mike Zolna1-Feb-01 4:54 Mike Zolna 1-Feb-01 4:54  Actually, The elements of the array are from 0-255, or 00 to FF in hex. I need to combine both bytes and turn them into a signed character for processing. Regards Mike Re: Converting integers from array to integer variables David Fedolfi1-Feb-01 3:59 David Fedolfi 1-Feb-01 3:59  Well, this is not efficient, but shoudl serve as a starting point for you: long lResult = 0; int nMult; for (int x = 0; x< nNum; x++) { nMult = 1; while (nMult <= nArray[x]) nMult *= 10; lResult *= nMult; lResult += nArray[x]; } Note though that if your array has any significant size then you will overflow the integer you're trying ot store it into. Re: Converting integers from array to integer variables .::RockNix::.31-Jan-01 21:48 .::RockNix::. 31-Jan-01 21:48  If your numbers are in range of -signed char- it`s very easy to combine these numbers to an integer: int result = ( array[0] << 8 ) + array[1]; This command shifts the number stored in array[0] 8 Bit up (left) and adds the number stored in array[1]; Hope that helps Greatings Mario /// -------------------- www.klangwerker.de rocknix@lycos.de -------------------- Re: Converting integers from array to integer variables .::RockNix::.31-Jan-01 21:50 .::RockNix::. 31-Jan-01 21:50  If your numbers are in range of -signed char- it`s very easy to combine these numbers to an integer: int result = ( array[0] << 8 ) + array[1]; This command shifts the number stored in array[0] 8 Bit up (left) and adds the number stored in array[1]. Shifting a byte by 8 is equal to a multiplikation with 0xff - but shifting is much faster I think.

The child is a Win32 Console program and I need to be able to read in the output of the Child through a pipe. I tried taking a look at the Example in the MSDN stuff, but it didn't even seem to do anything as far as passing the data back and forth. Could someone give me a few tips or point me to a tutorial?

Debugging problem with VC++6 on Win2000 31-Jan-01 0:09 31-Jan-01 0:09  When I step through my source code when debugging my application (F10), sometimes the system suddenly hangs. The only thing I can do is move the mouse pointer and then I'll always have to reboot my machine. Has anyone ever experienced the same or know a solution to this annoying problem. Platform: Win 2000 SP1; VC++6 SP4 Our application is a multithreaded application that also uses ADO. Thanks in advance.

You don't happen to know any electronical version of that chapter/book? Does Win2K behaves differently than WinNT for multithreading? 'Cause I don't have the problem (with the same code) on a WinNT machine. Bye. Geert.
