  • subview is not added immediately (iphone)

    - by Jonathan
    When the return button on the keyboard for a textfield is tapped I want to add a UIView, then connect to a website with NSURlConnection sendsynchronousrequest and I have the code in that order But when I run in the simulator (I can't run on device) the connection is run first then the subview is added (ie the opposite of the order of the code) Why is this and how can stop it, because I want the view to added, then the connection done and then the view removed.

  • Asp.Net Scrapping Grid Pages

    - by SH
    I need cod in C#. Look, i am trying to post the search.aspx page which contains Asp.Net grid. When grid is rendered it loads very first page on the screen and then there are number of pages in the grid header. I scrap first page, and now i want to move on to the next page. All this is being done using following code: HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://pubrec3.hillsclerk.com/oncore/search.aspx?" + param); myRequest.Method = "GET"; myRequest.KeepAlive = false; HttpWebResponse webresponse; try { webresponse = (HttpWebResponse)myRequest.GetResponse(); Encoding enc = System.Text.Encoding.GetEncoding(1252); StreamReader loResponseStream = new StreamReader(webresponse.GetResponseStream(), enc); string r = loResponseStream.ReadToEnd(); loResponseStream.Close(); webresponse.Close(); //if (GetRecordCount(r)) ExtractResultTable(bd, ed, r); } catch (Exception ex) { } The above code grabs first page... and now i have to move on to the next page. This is the link which produces a grid with 3 pages. http://pubrec3.hillsclerk.com/oncore/search.aspx?bd=01/01/2008&ed=12/31/2008&bt=O&lb=1000000&ub=1000000000&d=5/6/2010&pt=-1&dt=D,%20MTG&st=consideration Using above code i need to load the 2nd page with the same search criteria but the records found in 2nd page. and then so on. I know there is a trick to navigate through the grid pages. I used it but it did not work on this page. the trick is, you can pass __EVENTTARGET and __EVENTARGUMENT in query string to navigate through the gird but it does not work on this website. I am desperately searching a way, how to cope with this website. i really want this done. i do not want any code but a way to nevigate throgh the grid using query string if it does work. Otherwise please be specific to the problem.

  • sqlite 3 opening issue

    - by anonymous
    I'm getting my data ,with several similar methods, from sqlite3 file like in following code: -(NSMutableArray *) getCountersByID:(NSString *) championID{ NSMutableArray *arrayOfCounters; arrayOfCounters = [[NSMutableArray alloc] init]; @try { NSFileManager *fileManager = [NSFileManager defaultManager]; NSString *databasePath = [[[NSBundle mainBundle] resourcePath ]stringByAppendingPathComponent:@"DatabaseCounters.sqlite"]; BOOL success = [fileManager fileExistsAtPath:databasePath]; if (!success) { NSLog(@"cannot connect to Database! at filepath %@",databasePath); } else{ NSLog (@"SUCCESS getCountersByID!!"); } if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK){ NSString *tempString = [NSString stringWithFormat:@"SELECT COUNTER_ID FROM COUNTERS WHERE CHAMPION_ID = %@",championID]; const char *sql = [tempString cStringUsingEncoding:NSASCIIStringEncoding]; sqlite3_stmt *sqlStatement; int ret = sqlite3_prepare(database, sql, -1, &sqlStatement, NULL); if (ret != SQLITE_OK) { NSLog(@"Error calling sqlite3_prepare: %d", ret); } if(sqlite3_prepare_v2(database, sql, -1, &sqlStatement, NULL) == SQLITE_OK){ while (sqlite3_step(sqlStatement)==SQLITE_ROW) { counterList *CounterList = [[counterList alloc]init]; CounterList.counterID = [NSString stringWithUTF8String:(char *) sqlite3_column_text(sqlStatement,0)]; [arrayOfCounters addObject:CounterList]; } } else{ NSLog(@"problem with database prepare"); } sqlite3_finalize(sqlStatement); } else{ NSLog(@"problem with database openning %s",sqlite3_errmsg(database)); } } @catch (NSException *exception){ NSLog(@"An exception occured: %@", [exception reason]); } @finally{ sqlite3_close(database); return arrayOfCounters; } //end } then i'm getting access to data with this and other similar lines of code: myCounterList *MyCounterList = [[myCounterList alloc] init]; countersTempArray = [MyCounterList getCountersByID:"2"]; [countersArray addObject:[NSString stringWithFormat:@"%@",(((counterList *) [countersTempArray objectAtIndex:i]).counterID)]]; I'm getting a lot of data like image name and showing combination of them that depends on users input with such code: UIImage *tempImage = [UIImage imageNamed:[NSString stringWithFormat:@"%@_0.jpg",[countersArray objectAtIndex:0]]]; [championSelection setBackgroundImage:tempImage forState:UIControlStateNormal]; My problem: When i'm run my app for some time and get a lot of data it throws error: " problem with database openning unable to open database file - error = 24 (Too many open files)" My guess is that i'm opening my database every time when getCountersByID is called but not closing it. My question: Am i using right approach to open and close database that i use? Similar questions that have not helped me to solve this problem: unable to open database Sqlite Opening Error : Unable to open database UPDATE: I made assumption that error is showing up because i use this lines of code too much: NSFileManager *fileManager = [NSFileManager defaultManager]; NSString *databasePath = [[[NSBundle mainBundle] resourcePath ]stringByAppendingPathComponent:@"DatabaseCounters.sqlite"]; BOOL success = [fileManager fileExistsAtPath:databasePath]; and ending up with error 24. So i made them global but sqlite3_errmsg shows same err 24, but app runs much faster now I'll try to debug my app, see what happens

  • disable Opera function key in javascript

    - by DonDon
    I'm writing javascript code for a web emulator containing function keys. The user is able to press keyboard function keys to process something in the emulator, I used stopPropagation and preventDefault javascript function to stop/cancel browsers invoking their function key shortcut (e.g. F1 will invoke Firefox to open its help page) and the code works fine under Firefox and Chrome. But Opera didn't work. I'm using latest Opera 10.5 here. Can anyone help ?

  • Pass PHP variables without being seen when working with a database generated list

    - by Wilcoholic
    Looking for any help regarding the problem. Here's the deal: I have a database that has a teams table and it contains team_id. On one of my pages, I generate a list of links that contain the team_id of the creator in their get URL. I need the team_id on the next page but can't figure out how to pass it through any other way. Using a form and POST isn't an option because this method would only pass through the last links data on the list. Storing in a session isn't an option either because there is no way to discretely pass the the variables I need to a function to set the session variables. I have tried and it can pretty easily be viewed from viewing the source code. So here's some sample code to see exactly what I'm dealing with. <? if(mysql_num_rows($result2)>0){ ?> <a class="fltrt btn btn-danger btn-small" onclick="test()" href="acceptmatch-exec.php?match_id=<?php echo $match_id; ?>&team_id=<?php echo $team_id;?>&action=cancel">Cancel Match</a> <?}else{?> <a class="fltrt btn btn-success btn-small" href="acceptmatch-exec.php?match_id=<?php echo $match_id; ?>&team_id=<?php echo $team_id;?>&action=accept">Accept Match</a> <?} ?> The code above is generated multiple times on a page via a while loop that was excluded. I want to pass the match_id and team_id variables without being seen anywhere. If I made this a form, it wouldn't pass the correct variables unless there is only one result at the time (not likely). I'm sure there has to be an easy method that is eluding me, so please share thoughts on how to solve this. I feel as though I am not explaining it well enough, but it's not really easy to explain. I basically want something that works like GET but acts like POST and can be hidden from people viewing source code or link locations. Thanks

  • CSS Error when using jQuery's gt() selector?

    - by kimka
    I've noticed that Firefox throws me a warning on the following jQuery code: $("li.example div.code:gt(4)").hide(); CSS Error: Unknown pseudo-class or pseudo-element 'gt'. According to jQuery, it all should be correct. And it works, but I wonder how to fix this error for cleanness sake.

  • relaunch app when it ends or when it prints out certain text (stdout)

    - by acidzombie24
    I have an app which acts almost like a daemon. Sometimes it quits on error and many times it prints an error msg then ask users to press any key to close. How can i relaunch the app when either case happens? I am more interested in the 2nd case. I can do this in c++, C# or python. The script is an old python that i dont want to change (a newer c# version is in the works but not stable)

  • Easiest way to choose a percentage of an amount of rows from a MySQL table?

    - by Rob
    I have a script that has a GET variable: $_GET['percentage'] I have a MySQL table of data. Now lets say that there are 100 rows of data in this table. In pseudo-code: SELECT data FROM table Now would it be possible to select $_GET['percentage'] of random data from table? For example (again in pseudo-code): $_GET['percentage'] = 10; SELECT 10% of data from table order by rand() If this IS possible, how could I do it?

  • Best practices for handling binary data in Ruby?

    - by StackedCrooked
    What are the best practices for reading and writing binary data in Ruby? In the code sample below I needed to send a binary file using over HTTP (as POST data): f = File.new("resp.der", "r") # binary file begin while true out.syswrite(f.sysread(1)) # out is an output stream (type IO) end rescue EOFError => err puts "Sent response." end While this code seems to do a good job, it probably isn't very idiomatic. How can I improve it?

  • Does "make install", by convention, updates the targets it installs?

    - by Pavel Shved
    You usually invoke the following commands to build a ./configured product: make make install Okay, the product is in the system now. Then you change some source code files and invoke only make install. The question is, does the conventional implementation of install target requires the executables to be recompiled, or just the old ones should be copied to the appropriate system path?

  • How to resize an image smoothly (with resampling) using Windows API calls?

    - by Clay Nichols
    I need to resize images and resample them so they don't end up all jagged (I think that's called aliasing). I found some code (sorry, lost the link) that does this in pure VB6 code but it's a bit slow (2-5 seconds) and I'm displaying pictures in real time so I need something faster. I seem to recall seeing some examples of doing this with the GDI+ library. An example in VB6 would be ideal, but I can probably work with a simple example with Windows API calls in another language.

  • LAbeling with Percentage in R plot

    - by Libo Cannici
    Hi I have made this function that takes a table and prepare the label for a barplot prepare_labels <- function(ft){ labs <- ft labs <- paste(labs, "\n", sep="") labs <- paste(labs, round(prop.table(ft)*100,2), sep="") labs <- paste(labs, "%", sep="") return(labs) } It actually works fine, but is there any better way to write that function, the above code looks ugly and I want to write beautiful code :-) ex: ft <- table(mydata$phone_partner_products) prepare_labels(ft) [1] "3752\n34.09%" "226\n2.05%" "2907\n26.41%" "1404\n12.76%" "1653\n15.02%" [6] "1065\n9.68%"
