    Re: three way merging of xml documents

    DOM: reads the entire xml in memory. you can then query the DOM via XPath. the advantage is that you can go back and forth as many times as you want. the disadvantage is that it needs memory for the...

    Re: Bool type problem

    this is actually at the core of the reasoning. And it has everything to do with the "members of structures" and "alignment".

    bitfields only accumulate into a larger type in so far as the larger...

    Re: Bool type problem

    This is just there because on a 16bit compiler, the size of an int will be different.
    in case you want to know,
    on a 16bit compiler, the sizeof will be either 4 or 6, depending on the compiler...

    Re: More CopyFile Problems

    is the file physically empty when you open it ?
    or is it just in the directory/explorer that it is listed as 0? (this is normal, to a degree)

    Are you sure the file you are copying FROM has been...

    Re: Bool type problem

    I do have support in the standard. Feel free to find it. Or alternatively, show me the 32-bit or higher compiler where it's less than 8.

    This is actually part of the "headache" issues I pointed...
  6. Re: What technologies to use for modern Windows client development?

    It never died, so it didn't need resurrecting.



    same here, it is not in a coma, and it isn't on minimal life support.


    Minimal life support would mean that Microsoft just puts in the...

    Re: Bool type problem

    Regardless of implementation, for a compiler adhering to the standard, you'll get (at least) 8 bytes. And yes, I DO know that.

    which 4x1bit and 1x4bits you get out of the 8 bytes is however...
  8. Re: What technologies to use for modern Windows client development?

    MFC has not been abandoned. it is still being supported and augmented. Although granted, it isn't a primary focus.

    Considering it's age, it's actually better supported than some other newer...

    Re: Bool type problem

    because it's documented to be that way. You have to find the bits and bobs from a few different places in the manual though.

    Feel free to actually try it out.

    Re: Bool type problem

    Like 2Kaud said: this is something called 'bitfields'.
    Avoid using it, it is likely to cause you more headaches than it's worth.

    The idea behind it is that you can use fewer bits and thus use...
  12. Thread: Xpath or DOM?

    Re: Xpath or DOM?

    XPath is the means by which you query a DOM (typically loaded from XML, but this isn't a necessity). It's a "query language" allowing you to select one or more nodes from a DOM.

    or if you want an...
  13. Re: What technologies to use for modern Windows client development?

    WPF is one way, it is not necessarily the 'only' or 'the best' way.
    WPF also isn't the latest concoction some devs at MS conjured up, and it'll get 'old' soon enough as well.

    Re: Need some help on Watcom assembling....

    Wasm has built in support for the DOS4GW (later called CauseWay) DOS extender.
    This essently just means it'll link in the setup/interface/cleanup for the extender as well. IIRC, this lib isn't just...

    Re: how can I get rid of these downcasts?

    1) the totalcost approach in XBuilding is your problem area.

    Either the base class needs to have an accumulation of the total (by having the totalCost double as member of the base class instead of...

    Re: Need some help on Watcom assembling....

    The inc command should assemble. If not, try adding square brackets around the variable name (some assemblers are picky about that).

    but you will need to have code somewhere that initializes it...

    Re: Need some help on Watcom assembling....

    You cannot typically take decompiled output and use that as source for an assembler.

    An assembler will typically need additional information the disassembler doesn't provide
    and a disassembler...

    Re: slow upload rate to vxworks server

    FTP has a considerable overhead on each file transfer. For 17000 that's going to count up.
    - Consider using queued down/uploads
    - part of the delay is in authentication, you can speed that up by...

    Re: What do developers do all day?

    10% write code
    30% debug code
    30% write help/documentation
    40% look on the 'net for samples of how that darn API works.

    yes that's 110% ! Always on overdrive.
  21. Re: how are websites like PcPartpicker developed? What coding language?

    could be anything.

    it mainly depends on what webserver software you'll be using.
    if using MS IIS, then you'll probably do most of the server side scripting in asp.net and use SQL server as...

    Re: Beginner Visual C++ Application Question

    I didn't claim MFC doesn't have uses. I clearly stated it handles the common scenario's well enough.

    But saying it encapsulates "most of the windows API" is a big stretch. Maybe if you mean...
