  1. Re: Video-Decompression with the VCM (ICM-Win32-API)

    Sure, saved me half an hour or so - and (other than diles WIA-based solution) it was not
    only a very *performant* solution (suiteable for live-rendering with 30 -even 60 FPS) -
    but *also* very...
  2. Re: Video-Decompression with the VCM (ICM-Win32-API)

    Glad we agree so far.



    You mean, the fact that I posted an URL to the Demo-Source as a *.zip is somehow "despicable"?

    Just a small example, how to use the ICM-API (hosted in msvfw32.dll), to decode

    Re: How to mamage files with non-English names?

    Since your SQL-statement doesn't contain any 'Order By'-Clause, it is entirely up to
    the DB-engine, in what order it hands out the resulting records to you.

    Re: From C# to VB6

  24. Re: [RESOLVED (or sort of...)]Evaluating boolean value of a string...?

    There's no bias against one method or the other - since both are valid algorithms in their own right.
    For certain scenarios one would be choosen over the other.

  28. Re: Using a mathematical identity to speed up certain calculations.

    It's about 650 times slower - but yes, the difference is quite large - and overproportionally so,
    when we e.g. compare it with the VB6-native-compiler-timing when I run the same task:

    FWIW, dug out some code from an old post of mine, which shows the usage

    what Tanner already mentioned.

    That's again wrong information - and as for trolling - IMO you're doing it
    the whole time in our "conversation" (if it may be called that).



    Nope - I can only repeat myself here - you so far...
  35. Re: Using a mathematical identity to speed up certain calculations.

    Sure - take a good look at the IIF-function and what it finally accomplishes,
    since that was the only thing I was struggling with the whole time, until the light
    finally came on... ;-)

    Yep - I'm trying to find a generic function which internally makes use of the O(1)-category n*(n+1)/2 approach,
    to avoid the O(n) looping over the whole range.
