  • Jquery Tools Tabs: How to capture onClick event when selection is on current tab?

    - by littlenewton
    Hi All, I tried to ask this question on the jquery tools forum, but didn't get a response, hopefully someone here can help. Question: It seems the onClick event does not get fired when user is already on current tab, I think that make sense for most cases. However, in my case, I do want to capture the onClick event even when the curent tab is already the selection. Is there a way to do this? Thanks!

  • What happened to the "Run" and "Run On" commands in Visual Studio 2010 Database Projects?

    - by Steve Elmer
    Hello, I have migrated a database project from VS2008 to VS2010. While in VS08, I used to be able to right-click on a .sql or .cmd file and select a "Run" or "Run On" command from the context menu. In VS2010, though, these menu items seem to have gone away. I have a number of .sql and .cmd scripts that I am used to being able to run directly from the Visual Studio IDE. Can someone point me in the right direction? Thanks, Steve

  • Information on Rojiani's Numerical methods C textbook

    - by yCalleecharan
    Hi, having taken a look at a few textbooks that discuss numerical methods and C programming, I was gladly surprised when browsing through "programming in C with numerical methods for engineers" by Rojiani. I understand of course it's important that one need to have a solid background in numerical methods prior to try implementing them on a computer. I would like to know if someone here has been using this book and if possible point out strengths and weaknesses of this textbook. Thanks a lot...

  • Is LuaJIT really faster than every other JIT-ed dynamic languages?

    - by Gabriel Cuvillier
    According to the computer language benchmark game, the LuaJIT implementation seems to beat every other JIT-ed dynamic language (V8, Tracemonkey, PLT Scheme, Erlang HIPE) by an order of magnitude. I know that these benchmarks are not representative (as they say: "Which programming language implementations have the fastest benchmark programs?"), but this is still really impressive. In practice, is it really the case? Someone have tested that Lua implementation?

  • passing multiple vectors to function by reference (using structure)

    - by madman
    Hi StackOverflow, Can someone tell me the correct way of passing multiple vectors to a function that can take only a single argument? (specifically for pthread_create (..) function) I tried the following but it does not seem to work :-( First, I created the following structure struct ip2 { void* obj; int dim; int n_s; vector<vector<vector<double> > > *wlist; vector<int> *nrsv; struct model *pModel; }; The threads that I have created actually needs all these parameters. Since im using pthreads_create I put all this in a structure and then passed the pointer to the structure as an argument to pthread_create (as shown). some_fxn() { //some code struct ip2 ip; ip.obj=(void*) this; ip.n_s=n_s; ip.wlist=&wlist; ip.nrsv=&nrsv; ip.pModel=pModel; ip.dim=dim; pthread_create(&callThd1[lcntr], &attr1, &Cls::Entry, (void*) &ip); } The Entry method looks something like this. void* Cls::Entry(void *ip) { struct ip2 *x; x = (struct ip2 *)ip; (reinterpret_cast<Cls1 *>(x->obj))->Run(x->dim,x->n_s, x->wlist, x->nrsv, x->pModel); } The Run method looks something like this. void Run(int dim, int n_c, vector<vector<vector<double> > > *wlist, vector<int> *nrsv, struct model* pModel ) { //some code for(int k = 0; k < n_c; ++k) { //some code end = index + nrsv[k]; //some code } I get the following error when I try to compile the program. error: no match for ‘operator+’ in ‘index + *(((std::vector<int, std::allocator<int> >*)(((unsigned int)k) * 12u)) + nrsv)’ Can someone tell me how to do it the right way.

  • What is the difference between JSON and Object Literal Notation?

    - by burak ozdogan
    Hi, Can someone tell me what is the main difference between a Javascript object defined by using "Object Literal Notation" and JSON object? According to a Javascript book it says this is an object defined by using Object Notation: var newObject = { prop1 : true, showMessage : function (msg) {alert(msg)} }; Why it is not a JSON object in this case? Just because it is not defined by using quotation marks? Thanks,
