• gcc compiling error on Solaris 10

  - by osman toker

  I want to compile a source code, but there are some compiling errors about __sync_xxx functions (__sync_bool_compare_and_swap etc.) GCC version on machine is 3.4.3 (it must be gcc 4.1 or over for supporting atomic builtins), so I have downloaded GCC v4.6, copied it to another directory (I didn't remove v3.4.3) then change the $PATH path for GCC but it doesn't work (the same error occurs). I want to ask that is only changing gcc path with export PATH=... enough for compiling with new GCC?

  - by user333984

  I have some high-performance C++ that I need to interface with Objective-C, is there any performance penalty to just dumping this code into a .mm file that contains my Objective-C code vs. leaving this code in a separate .cpp file and extern-ing all the functions I need to call from the .mm file?

• GCD function in matlab

  - by SalemFayad

  hi, i am looking for a way to implement the "gcd" function used in matlab in another language but i really cant understand the way it functions. it says in http://www.mathworks.com/access/helpdesk/help/techdoc/ref/gcd.html that: "[G,C,D] = gcd(A,B) returns both the greatest common divisor array G, and the arrays C and D, which satisfy the equation: A(i).*C(i) + B(i).*D(i) = G(i)." but it says nothing about how it calculates C and D. i would be grateful if someone has a clearer idea about this subject! thanks:)

• How can I detect which callback from an unmanaged dll causes a protected memory exception?

  - by Kristian Hebert

  I get a protected memory exception, but how can I know which call caused it, and why the callback function has moved? All the calls to unmanaged code are done in the same class as the callback functions, so I suppose that the addresses should not change, or am I totally wrong here?

• Gridview - Is it necessary to grab data from database every time a filter, sort, or paging event occ

  - by hamlin11

  Regarding gridviews that are not bound to a Data Source Control: In most GridView tutorials that I have seen, when just about any GridView event occurs, the end of the event handler will include BindDataGrid(). In some form, these BindDataGrid() functions 1) Grab data from the database 2) Assign any Filter or Sort expressions to the data, and 3) Bind the gridview to that data source (usually a DataView or DataTable. Is there a better way to provide filterable & sortable data to a GridView without having to hit the database so often? Thanks

• SQL Server backward compatibility in Entity Framework?

  - by shake

  Is there any backward compatibility in the entity framework between SQL Server 2008 and 2005? It seems the framework forces you to use the same provider for all the .edmx files in a solution. If you use the 2008 provider, data types like DateTime2 and functions like SysDateTime that are emitted by the framework to the underlying SQL query make it useless to use them against a SQL 2005 Server. Any way around this?

• How do I subvert computer idle detection on Windows?

  - by sharptooth

  In order to detect user absence GetLastInputInfo() can be used. I want to make GetLastInputInfo() return that I've just used keyboard/mouse all the time - as I've been actively using the computer so that whoever relies on GetLastInputInfo() thinks I'm actively using the computer. Can I use any Windows API functions to achieve that?
