Hi all,
i create this code for some conversion but i dont know waht is the mistake is present dere,
loop is not return,
please chk this code.
Value=72;
digits=7;
CString PDU::Bin(int Value, short digits)
{
CString Bin;
CString result;
short exponent=0;
result = CString("0"[0],32);
do{
if (Value & Power2(exponent)) {
result.Mid(32 - exponent-1, 1);
Value = Value ^ Power2(exponent);
}
exponent += 1;
} while (Value);
if (digits < 0) {
Bin = result.Mid(33 - exponent-1);
} else {
Bin = result.Right(digits);
}
return Bin;
}
int PDU::Power2(int exponent)
{
int Power2=0;
static int res[31+1];
int I;
if( exponent < 0 || exponent > 31)
if(res[0] = 0) {
res[0] = 1;
for(I = 1;I<30;I++) {
res[I] = res[I - 1] * 2;
}
res[31] = 0x80000000;
}
Power2 = res[exponent];
return Power2;
}
please help me.

Have you already tried
- to build a debug version
- set a breakpoint at the beginning of PDU::Bin(..)
- press F5 to start the Debugger
- and then - just step by F10/F11 to observe the variables evolution
?  virtual void BeHappy() = 0;

The code looks a bit involved what are you trying to do?

Eddington monkey coding.  You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

Neither do we. What does the code do? What is it supposed to do? Have you used the debugger to step through the code, observing the various states of Value, res, Bin, and result?"One man's wage rise is another man's price increase." - Harold Wilson

Hi everyone,
I have CERT_CONTEXT with me.
How do I get public key from a digital certificate as HCRYPTKEY to use with API like CryptEncrypt? (ie how to get HCRYPTKEY from CRYPT_BIT_BLOB)
How do I do the same for my private key? (ie how to get HCRYPTKEY from my private key)
Links to C++ examples / documentations are welcome
Thanks in advance.cheers

Hi,
I have to UDP based applications, one sends and one recieves. I am trying to send an IP address in a CString, but I would like to be able to break it down when I recive it.
So my CString str has a value of "10.7.50.18"
I want to know how I can break that down to
10
7
50
18
but bear in mind, that ip address CAN be a maximum of 3 digits...
I'm clueless

Use Find to find first occurence of ".", use return count in Left to extract your digits, remove left the count of characters up to "." and repeat.
For safety, always remove leading and trailing empty spaces before you start ( TrimLeft , TrimRight ).

CStringT::Tokenize[^] is your clue and answer.
Use _T(".") as the first parameter.
Refer to the sample in the documentation for more details.

CString csIP=172.16.0.12";
CString cs1,cs2,cs3,cs4;
int Index;
Index = csIP.Find(".");
cs1 = csIP.Mid(0,Index);
csIP = csIP.Mid(Index+1);
Index = csIP.Find(".");
cs2 = csIP.Mid(0,Index);
csIP = csIP.Mid(Index+1);
Index = csIP.Find(".");
cs3 = csIP.Mid(0,Index);
cs4 = csIP.Mid(Index+1);

it is good, but better would be looping and updating dynamic collection for all finding. "Opinions are neither right nor wrong. I cannot change your opinion. I can, however, change what influences your opinion." - David Crow

Thanks, that worked.
However, I get some gibberish at the end like "10.7.50.18ÍÍÍÍÍÍÍÍÍÍÍÍÍÍ", any way to prevent that?
Thanks again.

Silly me, I fixed it:
cs4.Format("%d", atoi(cs4.GetString()));
Thanks anyway!

I'm new to C++ and I'd love to learn more, If you have a better one feel free to post it.

did you read about the members of the CString class. Reading the doc is fundamental to get a programmer.  Press F1 for help or google it.

everything is written in MSDN, then why are you lurking here?, dear be polite to new programmer, remember you urself have started as beginner some day. "Opinions are neither right nor wrong. I cannot change your opinion. I can, however, change what influences your opinion." - David Crow

It's possible that he was never a beginer. Maybe he is a genius, started out as a top-notch programmer. Take a look at the articles he wrote, and you will get the idea.

Have you tried AfxExtractSubString()?
You could also do something like:
char s1[4], s2[4], s3[4], s4[4];
sscanf("10.7.50.18", "%[^.].%[^.].%[^.].%[^.]", s1, s2, s3, s4);"One man's wage rise is another man's price increase." - Harold Wilson

Hi
I'm looking to write a virtual disk in C/C++/Pascal,
that'll work just like a regular FAT32 partition
that is a part of a PC's hard drive.
1. Programming background:
- I've had a bit of C/C++ programming experience,
but my Pascal skills are better.
- I'm not exactly familiar with Assembly language,
but if some Assembly code were to find its way
into a C/C++/Pascal wrapped function, using a
technique called 'inline Assembly' (I think) and
all parameters and/or function results were to be
passed in or returned in the hosting high level
language, that'll work 
2. Wishes:
- As far as I understand, the control application
would probably have to be written as a TSR,
which means that it should take the least amount
of RAM possible; this would be useful if the user
would want to boot their PC with a BootCD, then
make a RAMdrive on the extended RAM, then perhaps
start (or create) one or more virtual disks within
that RAMdrive
- It'll have to be either already formatted, or
formattable with DOS's format.com, to either
FAT16 or FAT32, so long DOS can recognize it
- It'll have to have a drive letter assigned to
it, such as D: or E: where it's preferable for
either the user or via code to be able to
select a drive letter on demand; multiple disk
volumes should be loadable one after another,
on the same DOS session
- It should be able to create a new volume upon
request, and the user should be able to set
its size (or capacity)
- It should be loadable via AUTOEXEC.BAT or just
the command line prompt, and not via CONFIG.SYS
- It should work under either pure MSDOS mode or
in a DOS box under Windows 98/XP
- Option : it should be partitionable
- Option : it should be resizable (up to a point)
if size of total files in it is near
capacity
So - any ideas on how to make DOS virtual disks?
Thanks in advance

Well that's six questions, largely on the same subject, but I'm not exactly sure what you are asking. I suggest some research first into the subject you are interested in, and then come back with specifics.
