  1. Re: Matlab/Octave code/technique for making thin lines from thicker lines

    You're not really saying what kind of result you want, and/or how near to the ideal you want things to be.

    Do you want an outer outline ? an inner outline ? An average ? A weighted curve ?...
  2. Re: static class member in multithreaded environment

    Just declaring stuff atomic 'randomly' while it makes each individual element atomic is a surefire way to get into deadlocks and other forms of hard to debug problems.

  3. Re: Injecting keyboard scan codes at driver level

    Assuming you have the issue too (even though you should have created a new post instead of resurrecting ancient ones).

    See MSDN for SendInput().

    Encrypted exe's tend to be "evil" the kind of exe's that contain malicious code that they want hidden/obfuscated from an antivirus.

    THere's no good reason for a well behaving exe to be encrypted. ...

    Re: How to delete records in .txt file

    then you have Always been wrong.

    use SINGLE forward slashes
    or DOUBLE backslashes (because that's how C/C++ escapes strings).

    Re: cin and cin.get()

    outputing to cout/file: yes
    input via a file: yes
    handling the command line: yes (it's the primary use of console exe's afterall)

  10. Re: Where does my Application need redesigning and Speeding Up?

    There's no way around the fact that 10^12 times round a loop will take time. At these amounts, even a single Ás per loop will end up taking 10^6 seconds (or just over 11 days).

    If inside that...

    One cannot become a good encryption specialist, without also being a good cracker.

    part of knowing how and where to protect comes from knowing how a cracker goes about it's things.

    Re: decode this....

    looks like an encryption that turns 8bit binary data into 5bit "readable text"

    other than that, hard to tell. it's not a straightforward binary to 5bit conversion or the "password" and "Password"...

    Re: XML Parsing

    there rarely is a "best". if there was, then it would be only that one thing, because why use anything other than "best" ?

    Re: crypt a file [algorithm]

    an std::string ends at a binary zero, which is very likely to occur in a binary file like an image.

    you need to load the data into a vector/buffer, and pass that to the encryption instead of using...
  19. Re: Where does my Application need redesigning and Speeding Up?

    If your code takes "weeks", then it should be fairly Obvious where the bulk of the time is going to. You don't even need a profiler. A simple run through a debugger should give you the "this is the...
  20. Re: Need Suggestion to choose Visual Studio Version ...

    Yes, having 2 separate UI's does come at a cost of having to maintain 2 versions.
    But it also has advantages in that you can tailor each UI to the platform they're running on.

  21. Re: Need Suggestion to choose Visual Studio Version ...

    Yes. Providing the app can live with the fact it'll be Windows desktop only. Or rather the UI will, it's possible to split the backend and UI. Yes, I would even recommend MFC for a multiplatform...
