I have generated a MAP file for an MFC application with two threads. The load address in the MAP file is 0x00400000. But the program is showing a run-time error for an instruction at 0x77fcca41 which is refering to memory at 0xffffffff that could not be read. But there are no instruction at 0x77fcca41 in the MAP file. I would like to know whether anyone has come across such a problem and was able to trace the cause. If so some help is required

Debugging release builds using map files is outdated, unnecessary and inefficient. Simply enable debug information for your release build (be sure to do so for the compiler and linker) and debug as normal.

That address is in one of the OS DLLs. If you can repro the crash, run the EXE in the debugger and look at the stack trace when the crash happens. You can then look up the addresses that are on the stack.

That sounds like an odd requirement. Please explain.

how to replace '............344' with empty string from the string like:
'1. visual basic.net ............344'
i am using regular expression in vb.net
this is the sample code
sText = Regex.Replace(sText, " (\\.+)\\d+", "");
thanx

Im sorry but I dont understand what you said you have a string (...344) and now you want to replace this string with null string on c++ ?

After I've created a new resource (IDD_TBL_A_DLG) and open ClassWizard, ClassWizard tells me I have a new resource and do I want to create a new class for it. When I try to create the class for this resource, I get the following:
"Unable to open the files (C:\RetPlan\TableA.h, C:\RetPlan\TableA.cpp) for class CTableA".
However, the .cpp and .h files are created but the Wizard can not add to them!
Can anyone clue me in as to what is going on? This is a VC++ 6.0 Project and is 'dialog-based'.

Delete .aps, .clw, and .ncb files and restart IDE.

It's a known bug with VS6. The files get created, but ClassWizard just doesn't know about them. Clean up the project's temporary files, and then restart the IDE.

Thanks very much. This is the first time this had happened to me.

I am trying to hash a password using MD5 to get the resultant digest. These are taken from the example I am following (which is from a trusted authority):
• First get the bytes of the original password, assuming a "Latin-1" encoding. For the password "Baltimore1," these bytes are: 66 97 108 116 105 109 111 114 101 49 44 (i.e. the value of "B" is 66, "a" is 97, etc).
• Then get the MD5 hash of these bytes. MD5 is a standard, public algorithm. Once again, for the password "Baltimore1," these bytes work out as: 223 238 161 24 62 121 39 143 115 167 51 163 245 231 226 94
• Finally, create the new password by forming a string whose Latin-1 encoding is the bytes from the previous step. For the "Baltimore1," password, if this is string is written to the screen, it looks like: ßî¡_>y'?s§3£õçâ^(i.e. the 62 above is a ">", the 121 is a "y", etc).
However, whenever I perform the hash I don't get the same result, I get:
6, 156, 90, 148, 160, 205, 176, 131, 162, 231, 168, 208, 232, 207, 90, 241
and string: œZ” Í°ƒ¢ç¨ÐèÏZñ
The code extract I am using is:
...<br />
unsigned char* pszPwd = simple_digest( "md5", "Baltimore1", strlen("Baltimore1"), &len );<br />
...<br />
<br />
unsigned char* simple_digest( char* alg, char* buf, unsigned int len, unsigned int* olen )<br />
{<br />
const EVP_MD* m;<br />
EVP_MD_CTX ctx;<br />
unsigned char* ret;<br />
<br />
OpenSSL_add_all_digests();<br />
<br />
if ( !( m = EVP_get_digestbyname( alg ) ) )<br />
{<br />
return NULL;<br />
}<br />
<br />
if ( !(ret = (unsigned char*)malloc(EVP_MAX_MD_SIZE)) )<br />
{<br />
return NULL;<br />
}<br />
<br />
EVP_DigestInit( &ctx, m );<br />
EVP_DigestUpdate( &ctx, buf, len );<br />
EVP_DigestFinal( &ctx, ret, olen );<br />
<br />
return ret;<br />
}
This is using the OpenSSL library. I tried to do the hash with completely seperate code that performs a MD5 hash and it came to the same result!
Can anyone PLEASE point me to where I am going wrong?

For what it's worth i hashed "Baltimore1" with an MD5 algo i have and got 6, 156, 90, ...
I'd look at the source that tells you it should be 223, 238, 161, ...
...cmk

I agree, you can check the hash on http://pajhome.org.uk/crypt/md5/[^] and the hash is 069c5a94a0cdb083a2e7a8d0e8cf5af1 which starts with 06, 156

Hi everyone
I am trying to write a code for an IIR filter. And for that purpose i need to implement the below function in C :-
out[n] = in[n] - ((b1 * e^jw * out[n-1]) + (b2 * e^2jw * out[n-2]))
Now, am facing problem ... well, rather i have no idea , as to how to implement the e^jw function in C. The value of w is known to me and n = the sample number.
It would be great if anyone could help me out.
Thanks a lot !!

Is this what you need?
exp (x) - returns e to the power x, where e is the base of the natural logarithm

hey Judy
I knew of exp(x) , but what i need is a solution for e^jx, j being the complex number.

Ah, couldn't tell what j was - you didn't mention it in your original post and it's been way too long since I coded an IIR. Can't help with complex off the top of my head. I'd imagine someone somewhere has written a complex math library. Have you googled for that?
Judy

|

Yup , I did , there's a complex.h library available , but this library works only for C++ . I need for C.
|
|
|
|

The code depends on how you are representing your complex numbers in c, but what you need is
exp(jw) = cos(w) + j sin(w)
