  • What does the caret mean in C++/CLI?

    - by Owen
    I just came across this code and a few Google searches turn up no explanation of this mysterious (to me) syntax. Hashtable^ tempHash = gcnew Hashtable(iterators_); IDictionaryEnumerator^ enumerator = tempHash->GetEnumerator(); What the heck does the caret mean? (The gcnew is also new to me, and I asked about that here.)

  • Learning... anything really

    - by WebDevHobo
    I'm particularly interested in Windows PowerShell, but here's a somewhat more general complaint: When asking for help on learning something new, be it a small subject on PHP or understanding a class in Java, what usually happens is that people direct me towards the documentation pages. What I'm looking for is somewhat of a course. A deep explanation of why something works the way it does. I know my basic programming, like Java and C#. I've never seen C or C++, though I have seen a bit of assembler. I know what the Stack and Heap are, how boxing and unboxing works, why you have to deep-copy an array instead of copying the pointer and some other things. Windows PowerShell on the other hand, I know nothing about. And I notice that when reading the small document or some code, I usually forget what it does or why it works. What I am looking for is preferably, a nice tutorial that explains the beginnings, the concepts, and goes to more difficult things at a steady pace. The only thing documentation can do is explain what a function does. That's no good to me since I don't know what I want to do yet. I could read about a thousand functions, and forget about most of them, because I don't need to implement them right after it. Randomly wandering through the documentation doesn't do me any good. So conclude, what is a good tutorial on Windows Powershell? One which explains in clear language what is happening, one which builds on previous things learned. I don't think googling this is a good idea. Doing a Google search on this would turn up numerous tutorials. And experience tells me that you have to look long and hard to find the gem you're looking for. That's why I'm asking here. Because this is the place where you can find more experienced people. Many of the PowerShell guys among you will know the good ones already, and by asking you, I avoid wasting time that could be spent learning. So to summarize: I will not google this!

  • How to specify dll onload function for mingw32?

    - by aking1012
    I can compile DLLs properly using mingw and do the exports/imports stuff. What I am looking for is defining the dll onload function properly as you would in MS VC products. Google didn't turn up anything. Anyone have any ideas or a link to a tutorial? It was suggested that this code snippet be added to the question: extern "C" DLL_EXPORT BOOL APIENTRY DllMain(HINSTANCE hinstDLL, DWORD Reason, LPVOID LPV) And yes, this is what I am trying to do, but with mingw.

  • How do I preserve installed applications when migrating Ubuntu to another platform?

    - by michaeljoseph
    I'm looking at maybe moving from an older AMD64 to a new Intel dual-core which is 32 bit. Installation isn't a problem but can I transfer all the installed apps? I haven't been able to find anything so far on Google except where the migration is to a similar platform and file-system. I won't change the filesystem but the platform will be different. Is there something on the lines of the "World" file in Gentoo?

  • Hide blocks on page not found in Drupal

    - by Tommy
    I have google adsense in a block, and I want to hide the block when the page is a "Page not found" error page. It's against adsenses TOS to show their ads on error pages. I figure there must be a way to write a php script to put in the Page specific visibility options. Does anyone know how to do this?

  • Are duplicate directives in php.ini going to cause an issue?

    - by Brandon G
    I sent a request to ops today to update some php.ini directives, and found out that he merely appended them to the end of the file. My google search didn't really come up with any info on whether this is a problem or not to have duplicates in there and how they would be parsed. Obviously, it can cause confusion, but, I would have a stronger argument if I knew if this was acceptable or not. Any input? Thanks in advance...

  • excluding posts in Wordpress

    - by Ayrton
    I wondered how I could exclude posts in Wordpress. E.g. I have a string $exclude_ids (= "4,5,6") or (="-4,-5,-6") and I would like to prevent these posts from showing up. How would I do that? I already tried: query_posts('p=' . $exclude_ids); but that didn't really work out and I didn't really find any information regarding this topic on google. Cheers

  • Approximate timings for various operations on a "typical desktop PC" anno 2010

    - by knorv
    In the article "Teach Yourself Programming in Ten Years" Peter Norvig (Director of Research, Google) gives the following approximate timings for various operations on a typical 1GHz PC back in 2001: execute single instruction = 1 nanosec = (1/1,000,000,000) sec fetch word from L1 cache memory = 2 nanosec fetch word from main memory = 10 nanosec fetch word from consecutive disk location = 200 nanosec fetch word from new disk location (seek) = 8,000,000 nanosec = 8 millisec What would the corresponding timings be for your definition of a typical PC desktop anno 2010?

  • Is it possible to have more than P2P on iPhone with Bluetooth

    - by Ricardo Ferreira
    Hi all, This seems like a straightforward google search answer, but after a while, I still can't be 100% sure of this. I've found Z2Live (http://www.z2live.com/), which is basically a layer above GameKit and they too use only P2P with Bluetooth. So I just want to be sure if I can only have P2P with Bluetooth or if I can have like 4 iPhones all connected to a server (who will also be a client) using Bluetooth. Thanks in advance.

  • Expression builder in Javascript or jQuery?

    - by morpheous
    I am searching for an expression builder GUI (like the one used in Microsoft Access). It can be plain Javascript or JQuery plugin. I am loathe to build my own and reinvent the wheel if one already exists - and yet, a search on Google does not find anything remotely useful. Is anyone aware of any such library/plugin or article that covers this?
