  • Proper way to resignFirstResponder when a UITableView is touched?

    - by Topher Fangio
    Hello all, I have a pretty simple UITableView who's cells contain UITextFields and I need to be able to call resignFirstResponder to hide the keyboard whenever a user touches the UITableView outside of one of the cells. I have read this question/answer but it seems like a very rudimentary way to achieve this. I have read about a way to do it by converting the UITableView to a UIControl so that you can connect the TouchDown event. Does anybody know the standard or preferred way to achieve this functionality?

  • Flash caroussel xml parse html link

    - by Marvin
    Hello I am trying to modify a carousel script I have in flash. Its normal function is making some icons rotate and when clicked they zoom in, fade all others and display a little text. On that text I would like to have a link like a "read more". If I use CDATA it wont display a thing, if I use alt char like &#60;a href=&#34;www.google.com&#34;&#62; Read more + &#60;/a&#62; It just displays the text as: <a href="www.google.com"> Read more + </a>. The flash dynamic text box wont render it as html. I dont enough as2 to figure out how to add this. My code: var xml:XML = new XML(); xml.ignoreWhite = true; //definições do xml xml.onLoad = function() { var nodes = this.firstChild.childNodes; numOfItems = nodes.length; for(var i=0;i<numOfItems;i++) { var t = home.attachMovie("item","item"+i,i+1); t.angle = i * ((Math.PI*2)/numOfItems); t.onEnterFrame = mover; t.toolText = nodes[i].attributes.tooltip; t.content = nodes[i].attributes.content; t.icon.inner.loadMovie(nodes[i].attributes.image); t.r.inner.loadMovie(nodes[i].attributes.image); t.icon.onRollOver = over; t.icon.onRollOut = out; t.icon.onRelease = released; } } And the xml: <?xml version="1.0" encoding="UTF-8"?> <icons> <icon image="images/product.swf" tooltip="Product" content="Hello this is some random text &#60;a href=&#34;www.google.com&#34;&#62; Read More + &#60;/a&#62; "/> </icons> Any suggestions? Thanks.

  • how to create box with sliding linked images

    - by paracaudex
    Where can I read more about creating linked slides like at the top of nytimes.com, slate.com, yahoo.com, nyu.edu, etc. I assume it's javascript, but I'm not sure what it's called, so I'm not sure how to look it up. I want to create a box at the top of a website with blocks of html text which slide in sequence if the user clicks next or after a certain amount of time. Where can I read more about this?

    - by Deepak N
    We deployed a VSTO addin for outlook 2003. After installing the addin one of the user's outlook crashes when a contact is opened, i.e, when ItemProperties of the contact are read.Some theses properties are read using MAPI.There is no exception being logged even though we have try/catch and logging in all methods. The event log has following message The description for Event ID 1000 from source Microsoft Office 11 cannot be found Source : Microsoft Office 11 The following information was included with the event: outlook.exe 11.0.8312.0 4a403990 msvcr80.dll 8.0.50727.3053 4889d619 0 0001500a

  • Android files manipulation

    - by klaus-vlad
    Hi, Through the housekeeping stuff my android application has to do is to read and write some files and sometimes to delete others and create new ones. The files in cause have all "sdcard/" as root. Is it safe if I perform all this task using Java style functions ? To me it is very handy to do it this way but I've read that not always the java functions can be applied when it comes to files in Android.

But I was wondering, if at the contrary I change my app from payed to free and some time after i want to re change it from free to payed! Can I? And if yes, Have I to wait some period (I have read something like this in the contract)? Tnk's Valerio From Italy

  • How can I access x:Name from Code Behind?

    - by viky
    I have a datagrid in which I am using DataGridTemplateColumn and DataGridTextColumn. I want to access these columns at runtime so I have assigned x:Name property to them. But I was not getting that value in code behind, so I looked for DataGrid and then read objects by iterating through DataGrid.Columns. How can I read x:Name property from that object in C#? I need this to perform some specific operations with particular columns at runtime.

  • OleDB Jet - Float issues in reading excel data

    - by Patrick
    When I read a sheet into a DataTable using the OleDbDataReader, floating point numbers loose their precision. I tried forcing OleDb to read the excel data as string, but although the data is now contained in a DataRow with each Column defined as System.String it looses precision (18.125 - 18.124962832). Any idea how to avoid this behaviour?

  • Easy way to convert a string of 0's and 1's into a character? Plain C

    - by Nick
    I'm doing a steganography project where I read in bytes from a ppm file and add the least significant bit to an array. So once 8 bytes are read in, I would have 8 bits in my array, which should equal some character in a hidden message. Is there an easy way to convert an array of 0's and 1's into an ascii value? For example, the array: char bits[] = "0,1,1,1,0,1,0,0" would equal 't'. Plain C

  • Reading Excel files from C#

    - by dbkk
    Is there a free or open source library to read Excel files (.xls) directly from a C# program? It does not need to be too fancy, just to select a worksheet and read the data as strings. So far, I've been using Export to Unicode text function of Excel, and parsing the resulting (tab-delimited) file, but I'd like to eliminate the manual step.

  • ReadFile doesn't work asynchronously on Win7 and Win2k8

    - by f0b0s
    According to MSDN ReadFile can read data 2 different ways: synchronously and asynchronously. I need the second one. The folowing code demonstrates usage with OVERLAPPED struct: #include <windows.h> #include <stdio.h> #include <time.h> void Read() { HANDLE hFile = CreateFileA("c:\\1.avi", GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_FLAG_OVERLAPPED, NULL); if ( hFile == INVALID_HANDLE_VALUE ) { printf("Failed to open the file\n"); return; } int dataSize = 256 * 1024 * 1024; char* data = (char*)malloc(dataSize); memset(data, 0xFF, dataSize); OVERLAPPED overlapped; memset(&overlapped, 0, sizeof(overlapped)); printf("reading: %d\n", time(NULL)); BOOL result = ReadFile(hFile, data, dataSize, NULL, &overlapped); printf("sent: %d\n", time(NULL)); DWORD bytesRead; result = GetOverlappedResult(hFile, &overlapped, &bytesRead, TRUE); // wait until completion - returns immediately printf("done: %d\n", time(NULL)); CloseHandle(hFile); } int main() { Read(); } On Windows XP output is: reading: 1296651896 sent: 1296651896 done: 1296651899 It means that ReadFile didn't block and returned imediatly at the same second, whereas reading process continued for 3 seconds. It is normal async reading. But on windows 7 and windows 2008 I get following results: reading: 1296661205 sent: 1296661209 done: 1296661209. It is a behavior of sync reading. MSDN says that async ReadFile sometimes can behave as sync (when the file is compressed or encrypted for example). But the return value in this situation should be TRUE and GetLastError() == NO_ERROR. On Windows 7 I get FALSE and GetLastError() == ERROR_IO_PENDING. So WinApi tells me that it is an async call, but when I look at the test I see that it is not! I'm not the only one who found this "bug": read the comment on ReadFile MSDN page. So what's the solution? Does anybody know? It is been 14 months after Denis found this strange behavior.

  • Several ifstream vs. ifstream + constant seeking

    - by SpyBot
    I'm writing an external merge sort. It works like that: read k chunks from big file, sort them in memory, perform k-way merge, done. So I need to sequentially read from different portions of the file during the k-way merge phase. What's the best way to do that: several ifstreams or one ifstream and seeking? Also, is there a library for easy async IO?

  • How do you determine an acceptable response time for App Engine DB requests?

    - by qiq
    According to this discussion of Google App Engine on Hacker News, A DB (read) request takes over 100ms on the datastore. That's insane and unusable for about 90% of applications. How do you determine what is an acceptable response time for a DB read request? I have been using App Engine without noticing any issues with DB responsiveness. But, on the other hand, I'm not sure I would even know what to look for in that regard :)

  • Basic shared memory program in C

    - by nicopuri
    Hi, I want to make a basic chat application in C using Shared memory. I am working in Linux. The application consist in writing the client and the server can read, and if the server write the client can read the message. I tried to do this, but I can't achieve the communication between client and server. The code is the following: Server.c int main(int argc, char **argv) { char *msg; static char buf[SIZE]; int n; msg = getmem(); memset(msg, 0, SIZE); initmutex(); while ( true ) { if( (n = read(0, buf, sizeof buf)) 0 ) { enter(); sprintf(msg, "%.*s", n, buf); printf("Servidor escribe: %s", msg); leave(); }else{ enter(); if ( strcmp(buf, msg) ) { printf("Servidor lee: %s", msg); strcpy(buf, msg); } leave(); sleep(1); } } return 0; } Client.c int main(int argc, char **argv) { char *msg; static char buf[SIZE-1]; int n; msg = getmem(); initmutex(); while(true) { if ( (n = read(0, buf, sizeof buf)) 0 ) { enter(); sprintf(msg, "%.*s", n, buf); printf("Cliente escribe: %s", msg); leave(); }else{ enter(); if ( strcmp(buf, msg) ) { printf("Cliente lee: %s", msg); strcpy(buf, msg); } leave(); sleep(1); } } printf("Cliente termina\n"); return 0; } The shared memory module is the folowing: #include "common.h" void fatal(char *s) { perror(s); exit(1); } char * getmem(void) { int fd; char *mem; if ( (fd = shm_open("/message", O_RDWR|O_CREAT, 0666)) == -1 ) fatal("sh_open"); ftruncate(fd, SIZE); if ( !(mem = mmap(NULL, SIZE, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0)) ) fatal("mmap"); close(fd); return mem; } static sem_t *sd; void initmutex(void) { if ( !(sd = sem_open("/mutex", O_RDWR|O_CREAT, 0666, 1)) ) fatal("sem_open"); } void enter(void) { sem_wait(sd); } void leave(void) { sem_post(sd); }

  • Monitoring UDP socket in glib(mm) eats up CPU time

    - by Gyorgy Szekely
    Hi, I have a GTKmm Windows application (built with MinGW) that receives UDP packets (no sending). The socket is native winsock and I use glibmm IOChannel to connect it to the application main loop. The socket is read with recvfrom. My problem is: this setup eats 25% percent CPU time on a 3GHz workstation. Can somebody tell me why? The application is idle in this case, and if I remove the UDP code, CPU usage drops down to almost zero. As the application has to perform some CPU intensive tasks, I could image better ways to spend that 25% Here are some code excerpts: (sorry for the printf's ;) ) /* bind */ void UDPInterface::bindToPort(unsigned short port) { struct sockaddr_in target; WSADATA wsaData; target.sin_family = AF_INET; target.sin_port = htons(port); target.sin_addr.s_addr = 0; if ( WSAStartup ( 0x0202, &wsaData ) ) { printf("WSAStartup failed!\n"); exit(0); // :) WSACleanup(); } sock = socket( AF_INET, SOCK_DGRAM, 0 ); if (sock == INVALID_SOCKET) { printf("invalid socket!\n"); exit(0); } if (bind(sock,(struct sockaddr*) &target, sizeof(struct sockaddr_in) ) == SOCKET_ERROR) { printf("failed to bind to port!\n"); exit(0); } printf("[UDPInterface::bindToPort] listening on port %i\n", port); } /* read */ bool UDPInterface::UDPEvent(Glib::IOCondition io_condition) { recvfrom(sock, (char*)buf, BUF_SIZE*4, 0, NULL, NULL); /* process packet... */ } /* glibmm connect */ Glib::RefPtr channel = Glib::IOChannel::create_from_win32_socket(udp.sock); Glib::signal_io().connect( sigc::mem_fun(udp, &UDPInterface::UDPEvent), channel, Glib::IO_IN ); I've read here in some other question, and also in glib docs (g_io_channel_win32_new_socket()) that the socket is put into nonblocking mode, and it's "a side-effect of the implementation and unavoidable". Does this explain the CPU effect, it's not clear to me? Whether or not I use glib to access the socket or call recvfrom() directly doesn't seem to make much difference, since CPU is used up before any packet arrives and the read handler gets invoked. Also glibmm docs state that it's ok to call recvfrom() even if the socket is polled (Glib::IOChannel::create_from_win32_socket()) I've tried compiling the program with -pg and created a per function cpu usage report with gprof. This wasn't usefull because the time is not spent in my program, but in some external glib/glibmm dll.
