  • Quick CPU ring mode protection question

    - by b-gen-jack-o-neill
    Hi, me again :) I am very curious in messing up with HW. But my top level "messing" so far was linked or inline assembler in C program. If my understanding of CPU and ring mode is right, I cannot directly from user mode app access some low level CPU features, like disabling interrupts, or changing protected mode segments, so I must use system calls to do everything I want. But, if I am right, drivers can run in ring mode 0. I actually don´t know much about drivers, but this is what I ask for. I just want to know, is learning how to write your own drivers and than call them the way I should go, to do what I wrote? I know I could write whole new OS (at least to some point), but what I exactly want to do is acessing some low level features of HW from standart windows application. So, is driver the way to go?

    I have a database with the following tables: Employee (EmpID, FirstName, LastName, RegionID) EmployeeSkills(EmpID, SkillID) [this is a linking table for the M:N relationship between Employees and skills] Skills(SkillID, Description) I need to list the name of the skill that most employees have. I tried doing a max(count(skillID)), sqlserver said that you can't do an aggregate function on an aggregate function. Any other ideas? Thank you in advance!

  • Java EE Module Dependencies in web project?

    - by Sled
    Hey guys, I have this webprojec to which I have to add a jar from another EJB project. Normally I'd right-click the webproject and go to properties - Java EE Module Dependencies. I don't know if it is because I upgraded eclipse, or i'm doing something wrong, but I just can't find the "Java EE Module Dependencies" in the properties window. Both projects are linked with the same EAR so the EJB jar file shuld be there! Any ideas what I'm doing wrong or some other way I could attach the EJB's JAR file? I'm only allowed to work with eclipse, so netbeans is not an option. Thanks! EDIT: basically, this is what I want to do, but that specific panel won't show up...

  • Contents changed(cleared?) when access the pointer returned by std::string::c_str()

    - by justamask
    string conf()     {         vector v;         //..         v = func(); //this function returns a vector         return v[1];     }     void test()     {         const char* p = conf().c_str();         // the string object will be alive as a auto var         // so the pointer should be valid till the end of this function,right?           // ... lots of steps, but none of them would access the pointer p         // when access p here, SOMETIMES the contents would change ... Why?         // the platform is solaris 64 bit         // compiler is sun workshop 12         // my code is compiled as  ELF 32-bit MSB relocatable SPARC32PLUS Version 1, V8+ Required         // but need to link with some shared lib which are ELF 32-bit MSB dynamic lib SPARC Version 1, dynamically linked, stripped     }

  • CF Client Variables: is the CDATA - CGLOBAL relationship always 1:1?

    - by ciaranarcher
    Hi We've noticed something odd with our Coldfusion 8 client variables DB. We have many more (about 3 times as many) CGlobal entries as we have CData entries. I would have assumed that the relationship would be 1:1 on the cfid column. Has any one else noticed this before? I have ruled out old data, my sample is less than 3 hours old. We're using SQL Server 2000 to host the tables. Thanks in advance, Ciaran

  • You do not have sufficient permissions to access this page.

    - by WmasterJ
    I recently set up a local copy of Wordpress, added some content and created a child theme. Then I moved it to my webserver, changed the config file, changed the "localhost" occurences in my SQL file to my online URL. I also changed my database prefix from what I had locally on all tables and in the config file. Everything works well on the outside. But then as I log-in is get the: You do not have sufficient permissions to access this page.

  • Unresolved External Symbol

    - by TomO
    I am working on wrapping a large number of .h and .lib files from native C++ to Managed C++ for eventual use as a referenced .dll in C#. I have the .lib files linked in and everything has been going smoothly so far. Upon wrapping the latest .h file, I hit a snag when 2 functions came back with the link error: error LNK2019: unresolved external symbol __imp__htonl@4 referenced in function "public: void __thiscall Field::setCharacter(unsigned char,int)" (?setCharacter@Field@@QAEXEH@Z) myutils.lib I have referenced "myutils.lib" in the linker options, so that shouldn't be the issue. What's strange is that I have about 20 functions in this particular .h file and all of the rest are linking just fine except for 3 functions. Any ideas?

  • Efficiency: what block size of kernel-mode memory allocations?

    - by Robert
    I need a big, driver-internal memory buffer with several tens of megabytes (non-paged, since accessed at dispatcher level). Since I think that allocating chunks of non-continuous memory will more likely succeed than allocating one single continuous memory block (especially when memory becomes fragmented) I want to implement that memory buffer as a linked list of memory blocks. What size should the blocks have to efficiently load the memory pages? (read: not to waste any page space) A multiple of 4096? (equally to the page size of the OS) A multiple of 4000? (not to waste another page for OS-internal memory allocation information) Another size? Target platform is Windows NT = 5.1 (XP and above) Target architectures are x86 and amd64 (not Itanium)

  • AngularJS directives with async content

    - by SirDavik
    I'm generating a dynamic number of Google Charts tables after receiving the content through an ajax request and I wanted to apply an accordion effect on them. I wanted to know if I could do that with directives (since if I just code render the angular tags they won't get interpreted). I don't need a code example, just a short answer to see if I should learn directives or if I should do it in a different way (I was thinking routeParams). Thanks!

  • In XHR, is it possible to distinguish network errors from cross-origin errors?

    - by greim
    http://www.w3.org/TR/access-control/ Reading the CORS spec linked above, it seems to be the case that it's impossible to reliably distinguish between a generic "network error" and a cross-origin access denied error. From the spec: If there is a network error Apply the network error steps. Perform a resource sharing check. If it returns fail, apply the network error steps. http://www.w3.org/TR/access-control/#simple-cross-origin-request0 In my testing, I couldn't locate any features of Firefox's implementation that seem to indicate that the resource sharing check definitely failed. It just switches readyState to 4 and sets status to 0. Ultimately I'd like the ability to pass a success callback, a general fail callback, and an optional cross-origin fail callback, to my function. Thanks for any help or insight.

  • First html5 website, see any mistakes?

    - by noxxten
    http://dl.dropbox.com/u/921159/designgoods/index.html I've made my first html5 website by converting another blog theme I had. It's actually a pretty sloppy job since its a learning experience and all. I know some files (like favicons and some scripts) are useless/not linked, but seeing as this is a test I won't bother creating them. But do you see any mistakes I made? Any 'better practices' to point out? :) Any C&C is very welcome and appreciated!
