  • Remotely running batches on a Windows PC

    - by Eduardo León
    I want to remotely control my home desktop PC (running Windows 7 Professional), mainly to perform the following tasks: Downloading email attachments, and sending emails with attachments Running UI-less programs whose only inputs are files and whose only outputs are files So far, the only solution I have found is to use Remote Desktop to connect to my PC, but this is very slow and inefficient, especially when there is no fast Internet connection available other than my cell phone's. I would like to be able to send batch commands to my PC, like: Download an email attachment Use it as input for an UI-less program Save the program's output to a file Send that file to myself as an email attachment Is this possible? How could I do it?

  • PHP mySQL count number of fields not empty

    - by Pez Cuckow
    I have a database of users where they can send messages to other users (up to four) and the ID of the message they sent is in their user row. e.g. Name, Email, Msg1, Msg2, Msg3, Msg4 Pez, [email protected], 1, 55, 42, 5 //Send 4 messages Steve, [email protected], 0, 0, 0, 0 //Send 0 messages Leon, [email protected], 3, 0, 3, 5 //Send 3 messages How in a MySQL query can I get the amount of those message rows that are not empty or not equal to 0, allowing me to order by that? So it would return Pez - 4 Mesasges Leon - 3 Messages Steve - 0 Messages Im my mind something like order by count(!empty(msg1)+!empty(msg2)+!empty(msg3)+!empty(msg4)) Many thanks,

  • DateTimePicker automatically move to next datepart

    - by Leon Tayson
    Currently, when using the datetimepicker, after you enter the month you have to either hit the right arrow or the "/" for it to move to the day. Is there a property that I can set or a way to know that the month is done and move to the day and move to the year after the user is done with the day? This is the same behavior with applications written in the old FoxPro/Clipper days.

  • Can't change background for UIWebView in iPhone SDK

    - by leon
    Hi, Is there a way to change background color for UIWebView? None of the colors set in IB effect UIWebView behavior: before acctual content is loaded it shows as up as white (causing a white flash between the moment it is loaded and content is rendered). Setting background color programmatically does not do anything either. Here is code: @interface Web_ViewViewController : UIViewController { UIWebView *web; } @property (nonatomic, retain) IBOutlet UIWebView *web; @end .... (void)viewDidLoad { super viewDidLoad; web.backgroundColor = UIColor blueColor; NSURL *clUrl = NSURL URLWithString:@"http://www.apple.com" ; NSURLRequest *req = NSURLRequest requestWithURL:clUrl; web loadRequest:req; } thanks

  • how to temporarily set makeprg in vim

    - by Haiyuan Zhang
    In the normal case I use vim's make utility I will set makeprg to the Makefile of the project I'm currently working for. Since usually the project will last for weeks or even longer, I don't need to change the setting of makeprg very often . But sometimes I need to write some "foobar" code either for practicing my c++ skill or for prototyping some primitive ideas in my mind. So whenever I switch to the "foobar" mode of vim usage, I need to comments the original makeprg setting add the new setting as following : au FileType c set makeprg=gcc\ % au FileType cpp set makeprg=g++\ % which is really very very inconvenient . when I back to the "normal project mode" of vim usage, I need to change back to the original setting . back and forth .... what I want to know from you guys is that : is it possible to make the setting of makeprg temporarily . for example , define a function in which first set a local value of makeprg and then call make before return form the function call automatically restore makeprg to the value before the function call.

  • jquery dynatree class methods

    - by Jj Zhang
    I'm a new user of dynatree plugin. When I read the documentation, I found the list of tree and node class member functions, such as tree.getRoot(), node.countChildren(). However, when I tried to use them, it complained that no such methods were found. Here is a sample code I am testing with: var tree = ("#test").dynatree(treeData); var rootNode = tree.getRoot(); //not working var rootNode2 = ("#test").dynatree("getRoot"); //this works var numChildren = rootNode2.countChildren(); //not working Help please. Thanks. -JJ

  • Problem with UIScrollView

    - by leon
    Hi, Sorry for long winded post. I am trying to understand UIScrollView and running into very simple problem. I am creating a scroll view I am making this view 1.5 size larger then normal size Using UIScrollView I expect to see some edge elements of view out of bounds, but should be able to pan the view therefore bringing missing elements back to the visible area. However I am seeing that I can't just pan/scroll view anyway I want, instead view always wants to scroll up, as soon as move away my finger from the screen (touch end event). I am not handling any touches, etc - I just want to understand why does not scaled view stay put where I scroll it? CGRect viewFrame = self.view.frame ; viewFrame.size.width *= 1.5; viewFrame.size.height *= 1.5; CGSize mySize = viewFrame.size; [ ((UIScrollView *) self.view) setContentSize: mySize]; self.view.transform = CGAffineTransformMakeScale(1.5, 1.5); What I really trying to accomplish is something similar to Number on iPad (the same code will work on iPhone): There is a view with lots of controls on it (order entry form) User can zoom into the entire form so all elements look bigger user can pan the form therefore bringing various elements into the visible area of the screen. It seems that UIScrollView can should be able to handle zoom and pan actions (for now I am using Affine Transform to zoom in to the order entry form and iPad) Thanks

  • wrapping boost::ublas with swig

    - by leon
    I am trying to pass data around the numpy and boost::ublas layers. I have written an ultra thin wrapper because swig cannot parse ublas' header correctly. The code is shown below #include <boost/numeric/ublas/vector.hpp> #include <boost/numeric/ublas/matrix.hpp> #include <boost/lexical_cast.hpp> #include <algorithm> #include <sstream> #include <string> using std::copy; using namespace boost; typedef boost::numeric::ublas::matrix<double> dm; typedef boost::numeric::ublas::vector<double> dv; class dvector : public dv{ public: dvector(const int rhs):dv(rhs){;}; dvector(); dvector(const int size, double* ptr):dv(size){ copy(ptr, ptr+sizeof(double)*size, &(dv::data()[0])); } ~dvector(){} }; with the SWIG interface that looks something like %apply(int DIM1, double* INPLACE_ARRAY1) {(const int size, double* ptr)} class dvector{ public: dvector(const int rhs); dvector(); dvector(const int size, double* ptr); %newobject toString; char* toString(); ~dvector(); }; I have compiled them successfully via gcc 4.3 and vc++9.0. However when I simply run a = dvector(array([1.,2.,3.])) it gives me a segfault. This is the first time I use swigh with numpy and not have fully understanding between the data conversion and memory buffer passing. Does anyone see something obvious I have missed? I have tried to trace through with a debugger but it crashed within the assmeblys of python.exe. I have no clue if this is a swig problem or of my simple wrapper. Anything is appreciated.

  • iPhone SDK: loading UITableView from SQLite

    - by leon
    Hi, I think I got a good handle on UITableViews and on getting/inserting data from/to SQLite db. I am straggling with an architectural question. My application saves 3 values int the database, there can be many/many rows. However would I load them in the table? From all the tutorials I have seen, at one point entire database is loaded in the NSMutableArray or similar object via performing SELECT statement. Then when -(UITableViewCell *) tableView: (UITableView *) tableView cellForRowAtIndexPath: (NSIndexPath *) indexPath called, rows required are dolled out from the previous loaded NSMutableArray (or similar stracture). But what i have have thousands for rows? Why would I pre-load them? Should I just query database each time cellForRowAtIndexPath is called? If so, what would I use as an index? Each row in the table will have an AUTOINCREMENT index, but since some rows may be deleted index will not correspond to rows in the table (in the SQL I may have something like this with row with index 3 missing): 1 Data1 Data1 2 Data2 Data2 4. data3 data3 Thanks

  • Code golf: Reverse quine

    - by Eduardo León
    Write a program that outputs the reverse of its source code as a string. If the source is abcd efg (i.e., the C string "abcd\nefg") Then the output should be gfe dcba (i.e., the C string "gfe\ndcba") Bonus points for using esoteric languages such as brainf*ck. *EDIT:** Removed the unnecessary \0 characters.+

  • how to manage a "resource" array efficiently

    - by Haiyuan Zhang
    The senario of my question is that one need to use a fixed size of array to keep track of certain number of "objects" . The object here can be as simply as a integer or as complex as very fancy data structure. And "keep track" here means to allocate one object when other part of the app need one instance of object and recyle it for future allocation when one instance of the object is returned .Finally ,let me use c++ to put my problme in a more descriptive way . #define MAX 65535 /* 65535 just indicate that many items should be handled . performance demanding! */ typedef struct { int item ; }Item_t; Item_t items[MAX] ; class itemManager { private : /* up to you.... */ public : int get() ; /* get one index to a free Item_t in items */ bool put(int index) ; /* recyle one Item_t indicate by one index in items */ } how will you implement the two public functions of itemManager ? it's up to you to add any private member .

  • How do you make sure email you send programmatically is not automatically marked as spam?

    - by Leon Bambrick
    This is a tricky one - and I've always relied on techniques such as permission-based emails (i.e. only sending to people you have permission to send to) and not using blatantly spamish terminology. Of late, some of the emails I send out programmatically have started being shuffled into people's spam folder automatically - and I'm wondering what i can do about it. This is despite the fact that these particular emails are not ones that humans would mark as spam (specifically, they are emails that contain license keys that people have paid good money for, so I don't think they're going to consider them spam) I figure this is a big topic in which I am essentially an ignorant simpleton.

Is it byte[vowels+p*2]? (since characters are 16 bit? ) Many thanks

  • Avoiding GC thrashing with WSE 3.0 MTOM service

    - by Leon Breedt
    For historical reasons, I have some WSE 3.0 web services that I cannot upgrade to WCF on the server side yet (it is also a substantial amount of work to do so). These web services are being used for file transfers from client to server, using MTOM encoding. This can also not be changed in the short term, for reasons of compatibility. Secondly, they are being called from both Java and .NET, and therefore need to be cross-platform, hence MTOM. How it works is that an "upload" WebMethod is called by the client, sending up a chunk of data at a time, since files being transferred could potentially be gigabytes in size. However, due to not being able to control parts of the stack before the WebMethod is invoked, I cannot control the memory usage patterns of the web service. The problem I am running into is for file sizes from 50MB or so onwards, performance is absolutely killed because of GC, since it appears that WSE 3.0 buffers each chunk received from the client in a new byte[] array, and by the time we've done 50MB we're spending 20-30% of time doing GC. I've played with various chunk sizes, from 16k to 2MB, with no real great difference in results. Smaller chunks are killed by the latency involved with round-tripping, and larger chunks just postpone the slowdown until GC kicks in. Any bright ideas on cutting down on the garbage created by WSE? Can I plug into the pipeline somehow and jury-rig something that has access to the client's request stream and streams it to the WebMethod? I'm aware that it is possible to "stream" responses to the client using WSE (albeit very ugly), but this problem is with requests from the client.

  • url with question mark considered as new http request?

    - by Navin Leon
    I am optimization my web page by implementing caching, so if I want the browser not to take data from cache, then I will append a dynamic number as query value. eg: google.com?val=823746 But some time, if I want to bring data from cache for the below url, the browser is making a new http request to server, its not taking data from cache. Is that because of the question mark in URL ? eg: http://google.com? Please provide some reference document link. Thanks in advance. Regards, Navin
