  • How to check if TypeIdenitifier(T) is an Object?

    - by John
    I'm creating a generic list class that has a member of type Array(Array of ). The problem is the class descruction,because the class is supposed to be used for types from byte to types inheriting TObject. Specifically: destructor Destroy; var elem:T; begin /*if(T is Tobject) then //Check if T inherits TObject {Compiler error!} for elem in FData do TObject(elem).Free;*/ // do not know how to do it SetLength(FItems,0); //FItems : Array of T inherited Destroy; end; How do I check if T is TObject so I can free every member if the typeidenitifier is a class,for example?

  • SmartGWT - Update ListGridRecord dynamically

    - by Haylwood
    I am using SmartGWT and I have a ListGrid populated with an array of ListGridRecords using the setData() call. I am trying to update a progress property of a single record (on a timer for testing) and have it update in the browser. I have tried various combinations of draw(), redraw(), markForRedraw() etc. to no avail. I also tried overriding the updateRecordComponent() method in my table class, but it only gets called when the records are first created (after createRecordComponent()). I should note that I do NOT want to accomplish this by binding to a DataSource. I just want to be able to update the attribute on the client-side. ArrayList<SegmentSortRecord> mRecords; mRecords.add(new SegmentSortRecord("03312010_M001_S004")); mRecords.add(new SegmentSortRecord("03312010_M001_S005")); mRecords.add(new SegmentSortRecord("03312010_M001_S006")); mRecords.add(new SegmentSortRecord("03312010_M001_S007")); SegmentSortRecord[] records = new SegmentSortRecord[mRecords.size()]; mRecords.toArray(records); mSortProgressTable.setData(records); . . . mTestTimer = new Timer() { public void run() { mTestPercent += 5; if (mTestPercent <= 100) { mSortProgressTable.getRecord(2).setAttribute(Constants.PROGRESS_COL_NAME, mTestPercent); //mSortProgressTable.markForRedraw(); //mSortProgressTable.redraw(); } else { mTestPercent = 0; } } }; ... @Override protected Canvas createRecordComponent(final ListGridRecord aRecord, Integer aColumn) { String fieldName = getFieldName(aColumn); // Want to override the behavior for rendering the "progress" field if (fieldName.equals(Constants.PROGRESS_COL_NAME)) { Progressbar bar = new Progressbar(); bar.setBreadth(10); bar.setLength(100); // The JavaScript record object contains attributes that we can // access via 'getAttribute' functions. bar.setPercentDone(aRecord.getAttributeAsInt(Constants.PROGRESS_COL_NAME)); return bar; } Thanks in advance for any help.

  • Calculating File size before download - Downloading NSURLConnection Slider timing

    - by sagar
    Ok ! Coming to the point directly. What I want to do is explained as follows. I have an url of MP3 file. ( for example Sound File ) Now, When user starts application. Download should start & for that I have implemented following methods. -(void)viewDidLoad { [super viewDidLoad]; NSURL *url=[NSURL URLWithString:@"http://xyz.pqr.com/abc.mp3"]; NSURLRequest *req=[NSURLRequest requestWithURL:url cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:120]; NSURLConnection *con=[[NSURLConnection alloc] initWithRequest:req delegate:self startImmediately:YES]; if(con){ myWebData=[[NSMutableData data] retain]; } else { // [MainHandler performSelector:@selector(targetSelector:) withObject:nil]; } } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { NSLog(@"%@",@"connection established"); [myWebData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSLog(@"%@",@"connection receiving data"); [myWebData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"%@",@"connection failed"); [connection release]; // [AlertViewHandler showAlertWithErrorMessage:@"Sorry, there is no network connection. Please check your network and try again."]; // [self parserDidEndDocument:nil]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; } Now, Above methods work perfectly for downloading. But missing points are as follows. I can not get the exact size which is going to be downloaded. ( means I want to know what is the size of file - which is going to be download )

  • Indy Write Buffering / Efficient TCP communication

    - by Smasher
    I know, I'm asking a lot of questions...but as a new delphi developer I keep falling over all these questions :) This one deals with TCP communication using indy 10. To make communication efficient, I code a client operation request as a single byte (in most scenarios followed by other data bytes of course, but in this case only one single byte). Problem is that var Bytes : TBytes; ... SetLength (Bytes, 1); Bytes [0] := OpCode; FConnection.IOHandler.Write (Bytes, 1); ErrorCode := Connection.IOHandler.ReadByte; does not send that byte immediately (at least the servers execute handler is not invoked). If I change the '1' to a '9' for example everything works fine. I assumed that Indy buffers the outgoing bytes and tried to disable write buffering with FConnection.IOHandler.WriteBufferClose; but it did not help. How can I send a single byte and make sure that it is immediatly sent? And - I add another little question here - what is the best way to send an integer using indy? Unfortunately I can't find function like WriteInteger in the IOHandler of TIdTCPServer...and WriteLn (IntToStr (SomeIntVal)) seems not very efficient to me. Does it make a difference whether I use multiple write commands in a row or pack things together in a byte array and send that once? Thanks for any answers! EDIT: I added a hint that I'm using Indy 10 since there seem to be major changes concerning the read and write procedures.

  • How to prevent latex memory overflow

    - by drasto
    I've got a latex macro that makes small pictures. In that picture I need to draw area. Borders of that area are quadratic bezier curves and that area is to be filled. I did not know how to do it so currently I'm "filling" the area by drawing a plenty of bezier curves inside it... This slows down typeseting and when a macro is used multiple times (so tex is drawing really a lot of quadratic bezier curves) it produces following error: ! TeX capacity exceeded, sorry [main memory size=3000000]. How can I prevent this error ? (by freeing memory after macro or such...) Or even better how do I fill the area determined by two quadratic bezier curves? Code that produces error: \usepackage{forloop} \usepackage{picture} \usepackage{eepic} ... \linethickness{\lineThickness\unitlength}% \forloop[\lineThickness]{cy}{\cymin}{\value{cy} < \cymax}{% \qbezier(\ax, \ay)(\cx, \value{cy})(\bx, \by)% }% Here are some example values for variables: \setlength{\unitlength}{0.01pt} \lineThickness=20 %cy is just a counter - inital value is not important \cymin=450 \cymax=900 %from following only the difference between \ax and \bx is important \ax=0 \ay=0 \bx=550 \by=0 Note: To reproduce the error this code have to execute approximately 150 times (could be more depending on your latex memory settings). Thanks a lot for any help

  • NSURL Connection will/won't load data

    - by jkap
    So here's my issue: I followed the NSURLConnection tutorial in the iPhone Developer Documentation almost to the T, and it only kinda works. Here's where it all goes wrong: The object seems to be created correctly and delegates to connectionDidFinishLoading, but with any URL I try to load the response data always ends up only being 0 bytes. I am running in the simulator if that makes any difference. Here's my relevant code: - (void)viewDidLoad { [super viewDidLoad]; self.title = @"WVFS Player"; //create a request NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://wvfs.josh-kaplan.com/nowPlaying.php"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; // create a connection NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if(theConnection) { // create the datum responseData=[[NSMutableData data] retain]; } else { // code this later } } - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [responseData setLength:0]; } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { // make it work NSLog(@"Succeeded! Received %d bytes of data:",[responseData length]); // release it [connection release]; [responseData release]; } And here's my log output: [Session started at 2010-03-14 09:01:09 -0400.] 2010-03-14 09:01:14.784 WVFS[19571:207] Succeeded! Received 0 bytes of data: Any ideas? Thanks, Josh

  • Asynchronous NSURLConnection Throws EXC_BAD_ACCESS

    - by Sheehan Alam
    I'm not really sure why my code is throwing a EXC_BAD_ACCESS, I have followed the guidelines in Apple's documentation: -(void)getMessages:(NSString*)stream{ NSString* myURL = [NSString stringWithFormat:@"http://www.someurl.com"]; NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:myURL]]; NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if (theConnection) { receivedData = [[NSMutableData data] retain]; } else { NSLog(@"Connection Failed!"); } } And my delegate methods #pragma mark NSURLConnection Delegate Methods - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { // This method is called when the server has determined that it // has enough information to create the NSURLResponse. // It can be called multiple times, for example in the case of a // redirect, so each time we reset the data. // receivedData is an instance variable declared elsewhere.

Even if that method simply contains an NSLog, I get the error. Note: receivedData is an NSMutableData* in my header file

  • How to change the margin of code's frame of showexpl.sty when numbers=none?

    - by suugaku
    Hi all, I want to align the code's frame with the formated text's frame. If the numbers=left,the mission is accomplished by configuring xleftmargin, xrightmargin, framesep, and numbersep. However, when I set numbers=none, I cannot accomplish my mission by configuring those properties. Regardless of the values set to those properties, the code's frame remains unchanged and expands beyond the \textwidth. Please see my code snippet below.

  • Suppress indentation after environment in LaTeX

    - by David
    I'm trying to create a new environment in my LaTeX document where indentation in the next paragraph following the environment is suppressed. I have been told (TeXbook and LaTeX source) that by setting \everypar to {\setbox0\lastbox}, the TeX typesetter will execute this at the beginning of the next paragraph and thus remove the indentation: \everypar{\setbox0\lastbox} So this is what I do, but to no effect (following paragraph is still indented): \newenvironment{example} {\begin{list} {} {\setlength\leftmargin{2em}}} {\end{list}\everypar{\setbox0\lastbox}} I have studied LaTeX's internals as well as I could manage. It seems that the \end routine says \endgroup and \par at some point, which may be the reason LaTeX ignores my \everypar setting. \global doesn't help either. I know about \noindent but want to do this automatically. Example document fragment: This is paragraph text. This is paragraph text, too. \begin{example} \item This is the first item in the list. \item This is the second item in the list. \end{example} This is more paragraph text. I don't want this indented, please. Internal routines and switches of interest seem to be \@endpetrue, \@endparenv and others. Thanks for your help.

  • How to update the user profile through tokenid when a particular user logs in using his username and password

    i have an application in which when the user enters his username and password in the login form , his username and password are submitted to the server database for validation and if he is a valid user a tokenid is generated for him through JSON response and he is allowed to log in.this is the JSON response that i get in the console when a valid user log in through the log in form : {"TokenID":"kaenn43otO","isError":false,"ErrorMessage":"","Result":[{"UserId":"164","FirstName":"Indu","LastName":"nair","Email":"[email protected]","ProfileImage":null,"ThumbnailImage":null,"DeviceInfoId":"22"}],"ErrorCode":900} 2011-06-24 11:56:57.639 Journey[5526:207] this is token id:kaenn43otO so when the same user wants to update his profile by clicking on the update tab using the tokenid So that if he want he can his firstname,lastname,password,email.etc.i i have done the following code to update the user profile using tokenid but it does not work.i get tokenid when the user log in and this tokenid i have to pass to other class: this is my code to update user profile: -(void)sendRequest { //this is the class in which i get the tokenid and i am passing it to this class apicontroller *apitest = [[apicontroller alloc]init]; NSString *tokentest = apitest.tokenapi; NSString *post = [NSString stringWithFormat:@"Token=%@&firstname=%@&lastname=%@&Username=%@&Password=%@&Email=%@",tokentest,txtfirstName.text,txtlast.text,txtUserName.text,txtPassword.text,txtEmail.text]; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; NSLog(@"%@",postLength); NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:@"http://192.168.0.1:96/JourneyMapperAPI?RequestType=Register&Command=SET"]]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; if (theConnection) { webData = [[NSMutableData data] retain]; NSLog(@"%@",webData); [theConnection start]; } else { } } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [webData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [webData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { [connection release]; [webData release]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { NSString *loginStatus = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding]; NSLog(@"%@",loginStatus); [loginStatus release]; [connection release]; [webData release]; } -(IBAction)click:(id)sender { [self sendRequest]; } this is my apicontroller.m file in which i am creating login form so that user login and in this page tokenid is generated -(void)sendRequest { UIDevice *device = [UIDevice currentDevice]; NSString *udid = [device uniqueIdentifier]; //NSString *sysname = [device systemName]; NSString *sysver = [device systemVersion]; NSString *model = [device model]; NSLog(@"idis:%@",[device uniqueIdentifier]); NSLog(@"system nameis :%@",[device systemName]); NSLog(@"System version is:%@",[device systemVersion]); NSLog(@"System model is:%@",[device model]); NSLog(@"device orientation is:%d",[device orientation]); NSString *post = [NSString stringWithFormat:@"Loginkey=%@&Password=%@&DeviceCode=%@&Firmware=%@&IMEI=%@",txtUserName.text,txtPassword.text,model,sysver,udid]; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; NSLog(@"%@",postLength); NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:@"http://192.168.0.1:96/JourneyMapperAPI?RequestType=Login"]]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; if (theConnection) { webData = [[NSMutableData data] retain]; NSLog(@"%@",webData); } else { } } //to select username and password from database. -(void)check { //app.journeyList = [[NSMutableArray alloc]init]; [self createEditableCopyOfDatabaseIfNeeded]; NSString *filePath = [self getWritableDBPath]; sqlite3 *database; if(sqlite3_open([filePath UTF8String], &database) == SQLITE_OK) { const char *sqlStatement = "SELECT Username,Password FROM UserInformation where Username=?

  • UIImage - should be loaded with [UIImage imageNamed:@""] or not ?

    - by sagar
    Hello ! every one. I am having number of images with in my application. ( images more than 50 - approximately & it can extend according to client's need ) Each image are very large round about - 1024 x 768 & 150 dpi Now, I have to add all this images in a scroll view & display it. Ok, My question is as follows. According to me there are two options of loading large images imageNamed:@"" load asynchronously when viewDidLoad Called. Which is more preferable ? imgModel.image=[UIImage imageNamed:[dMain valueForKey:@"imgVal"]]; or like this. NSURL *ur=[[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:lblModelName.text ofType:@"png"] isDirectory:NO]; NSURLRequest *req=[NSURLRequest requestWithURL:ur cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:40]; [ur release]; NSURLConnection *con=[[NSURLConnection alloc] initWithRequest:req delegate:self]; if(con){ myWebData=[[NSMutableData data] retain]; } else { } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [myWebData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [myWebData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { [connection release]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { NSLog(@"ImageView Ref From - %@",imgV); // my image view & set image imgV.image=[UIImage imageWithData:myWebData]; [connection release]; connection=nil; }

  • different thread accessing MemoryStream

    - by Wayne
    There's a bit of code which writes data to a MemoryStream object directly into it's data buffer by calling GetBuffer(). It also uses and updates the Position and SetLength() properties appropriately. This code works purposes 99.9999% of the time. Literally. Only every so many 100,000's of iterations it will barf. The specific problem is that the memory.Position property suddenly returns zero instead of the appropriate value. However, code was added that checks for the 0 and throws an exception which include log of the MemoryStream properties like Position and Length in a separate method. Those return the correct value. Further addition shows that when this rare condition occurs, the memory.Position only has zero inside this particular method. Okay. Obviously, this must be a threading issue. But this code is well locked. However, the nature of this software is that it's organized by "tasks" with a scheduler and so any one of several actual O/S thread may run this code at any give time--but never more than one at a time. So it's my guess that ordinarily it so happens that the same thread keeps getting used for this method and then on a rare occasion a different thread get used. Then due to compiler optimizations, the different thread never gets the correct value. It gets a "stale" value. Ordinarily in a situation like this I would apply a "volatile" keyword to the variable in question. But that (those) variables are inside the MemoryStream object. Does anyone have any other idea? Or does this mean we have to implement our own MemoryStream object? (Just like we end up having to do with practically every collection in .NET?) It's a shame to have such an awesome platform as .NET and have virtually the entire system useless as-is for seriously parallelized applications. If I'm wrong or you have other ideas, please advise. Sincerely, Wayne

  • Write file need to optimised for heavy traffic part 2

    - by Clayton Leung
    For anyone interest to see where I come from you can refer to part 1, but it is not necessary. write file need to optimised for heavy traffic Below is a snippet of code I have written to capture some financial tick data from the broker API. The code will run without error. I need to optimize the code, because in peak hours the zf_TickEvent method will be call more than 10000 times a second. I use a memorystream to hold the data until it reaches a certain size, then I output it into a text file. The broker API is only single threaded. void zf_TickEvent(object sender, ZenFire.TickEventArgs e) { outputString = string.Format("{0},{1},{2},{3},{4}\r\n", e.TimeStamp.ToString(timeFmt), e.Product.ToString(), Enum.GetName(typeof(ZenFire.TickType), e.Type), e.Price, e.Volume); fillBuffer(outputString); } public class memoryStreamClass { public static MemoryStream ms = new MemoryStream(); } void fillBuffer(string outputString) { byte[] outputByte = Encoding.ASCII.GetBytes(outputString); memoryStreamClass.ms.Write(outputByte, 0, outputByte.Length); if (memoryStreamClass.ms.Length > 8192) { emptyBuffer(memoryStreamClass.ms); memoryStreamClass.ms.SetLength(0); memoryStreamClass.ms.Position = 0; } } void emptyBuffer(MemoryStream ms) { FileStream outStream = new FileStream("c:\\test.txt", FileMode.Append); ms.WriteTo(outStream); outStream.Flush(); outStream.Close(); } Question: Any suggestion to make this even faster? I will try to vary the buffer length but in terms of code structure, is this (almost) the fastest? When memorystream is filled up and I am emptying it to the file, what would happen to the new data coming in? Do I need to implement a second buffer to hold that data while I am emptying my first buffer? Or is c# smart enough to figure it out? Thanks for any advice

  • objective-c uncompress/inflate a NSData object which contains a gzipped string

    - by user141146
    Hi, I'm using objective-c (iPhone) to read a sqlite table that contains blob data. The blob data is actually a gzipped string. The blob data is read into memory as an NSData object I then use a method (gzipInflate) which I grabbed from here (http://www.cocoadev.com/index.pl?NSDataCategory) -- see method below. However, the gzipInflate method is returning nil. If I step through the gzipInflate method, I can see that the status returned near the bottom of the method is -3, which I assume is some type of error (Z_STREAM_END = 1 and Z_OK = 0, but I don't know precisely what a status of -3 is). Consequently, the function returns nil even though the input NSData is 841 bytes in length. Any thoughts on what I'm doing wrong? Is there something wrong with the method? Something wrong with how I'm using the method? Any thoughts on how to test this? Thanks for any help! - (NSData *)gzipInflate { // NSData *compressed_data = [self.description dataUsingEncoding: NSUTF16StringEncoding]; NSData *compressed_data = self.description; if ([compressed_data length] == 0) return compressed_data; unsigned full_length = [compressed_data length]; unsigned half_length = [compressed_data length] / 2; NSMutableData *decompressed = [NSMutableData dataWithLength: full_length + half_length]; BOOL done = NO; int status; z_stream strm; strm.next_in = (Bytef *)[compressed_data bytes]; strm.avail_in = [compressed_data length]; strm.total_out = 0; strm.zalloc = Z_NULL; strm.zfree = Z_NULL; if (inflateInit2(&strm, (15+32)) != Z_OK) return nil; while (!done) { // Make sure we have enough room and reset the lengths. if (strm.total_out >= [decompressed length]) [decompressed increaseLengthBy: half_length]; strm.next_out = [decompressed mutableBytes] + strm.total_out; strm.avail_out = [decompressed length] - strm.total_out; // Inflate another chunk. status = inflate (&strm, Z_SYNC_FLUSH); NSLog(@"zstreamend = %d", Z_STREAM_END); if (status == Z_STREAM_END) done = YES; else if (status != Z_OK) break; //status here actually is -3 } if (inflateEnd (&strm) != Z_OK) return nil; // Set real length. if (done) { [decompressed setLength: strm.total_out]; return [NSData dataWithData: decompressed]; } else return nil; }

  • Strange behavior of move with strings

    - by Umair Ahmed
    I am testing some enhanced string related functions with which I am trying to use move as a way to copy strings around for faster, more efficient use without delving into pointers. While testing a function for making a delimited string from a TStringList, I encountered a strange issue. The compiler referenced the bytes contained through the index when it was empty and when a string was added to it through move, index referenced the characters contained. Here is a small downsized barebone code sample:- unit UI; interface uses System.SysUtils, System.Types, System.UITypes, System.Rtti, System.Classes, System.Variants, FMX.Types, FMX.Controls, FMX.Forms, FMX.Dialogs, FMX.Layouts, FMX.Memo; type TForm1 = class(TForm) Results: TMemo; procedure FormCreate(Sender: TObject); end; var Form1: TForm1; implementation {$R *.fmx} function StringListToDelimitedString ( const AStringList: TStringList; const ADelimiter: String ): String; var Str : String; Temp1 : NativeInt; Temp2 : NativeInt; DelimiterSize : Byte; begin Result := ' '; Temp1 := 0; DelimiterSize := Length ( ADelimiter ) * 2; for Str in AStringList do Temp1 := Temp1 + Length ( Str ); SetLength ( Result, Temp1 ); Temp1 := 1; for Str in AStringList do begin Temp2 := Length ( Str ) * 2; // Here Index references bytes in Result Move ( Str [1], Result [Temp1], Temp2 ); // From here the index seems to address characters instead of bytes in Result Temp1 := Temp1 + Temp2; Move ( ADelimiter [1], Result [Temp1], DelimiterSize ); Temp1 := Temp1 + DelimiterSize; end; end; procedure TForm1.FormCreate(Sender: TObject); var StrList : TStringList; Str : String; begin // Test 1 : StringListToDelimitedString StrList := TStringList.Create; Str := ''; StrList.Add ( 'Hello1' ); StrList.Add ( 'Hello2' ); StrList.Add ( 'Hello3' ); StrList.Add ( 'Hello4' ); Str := StringListToDelimitedString ( StrList, ';' ); Results.Lines.Add ( Str ); StrList.Free; end; end. Please devise a solution and if possible, some explanation. Alternatives are welcome too.

  • BufferedReader no longer buffering after a while?

    - by BobTurbo
    Sorry I can't post code but I have a bufferedreader with 50000000 bytes set as the buffer size. It works as you would expect for half an hour, the HDD light flashing every two minutes or so, reading in the big chunk of data, and then going quiet again as the CPU processes it. But after about half an hour (this is a very big file), the HDD starts thrashing as if it is reading one byte at a time. It is still in the same loop and I think I checked free ram to rule out swapping (heap size is default). Probably won't get any helpful answers, but worth a try. OK I have changed heap size to 768mb and still nothing. There is plenty of free memory and java.exe is only using about 300mb. Now I have profiled it and heap stays at about 200MB, well below what is available. CPU stays at 50%. Yet the HDD starts thrashing like crazy. I have.. no idea. I am going to rewrite the whole thing in c#, that is my solution. Here is the code (it is just a throw-away script, not pretty): BufferedReader s = null; HashMap<String, Integer> allWords = new HashMap<String, Integer>(); HashSet<String> pageWords = new HashSet<String>(); long[] pageCount = new long[78592]; long pages = 0; Scanner wordFile = new Scanner(new BufferedReader(new FileReader("allWords.txt"))); while (wordFile.hasNext()) { allWords.put(wordFile.next(), Integer.parseInt(wordFile.next())); } s = new BufferedReader(new FileReader("wikipedia/enwiki-latest-pages-articles.xml"), 50000000); StringBuilder words = new StringBuilder(); String nextLine = null; while ((nextLine = s.readLine()) != null) { if (a.matcher(nextLine).matches()) { continue; } else if (b.matcher(nextLine).matches()) { continue; } else if (c.matcher(nextLine).matches()) { continue; } else if (d.matcher(nextLine).matches()) { nextLine = s.readLine(); if (e.matcher(nextLine).matches()) { if (f.matcher(s.readLine()).matches()) { pageWords.addAll(Arrays.asList(words.toString().toLowerCase().split("[^a-zA-Z]"))); words.setLength(0); pages++; for (String word : pageWords) { if (allWords.containsKey(word)) { pageCount[allWords.get(word)]++; } else if (!word.isEmpty() && allWords.containsKey(word.substring(0, word.length() - 1))) { pageCount[allWords.get(word.substring(0, word.length() - 1))]++; } } pageWords.clear(); } } } else if (g.matcher(nextLine).matches()) { continue; } words.append(nextLine); words.append(" "); }

    hello again, i am trying to develop an downloadmanager. i can now download files from almost anywhere on linkclick. in the - (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType i check if the url is a url to a binaryfile like a zipfile. than i setup a nsurlconnection NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:20.0]; [urlRequest setValue:@"User-Agent" forHTTPHeaderField:@"Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en) AppleWebKit/418.9 (KHTML, like Gecko) Safari/419.3"]; NSURLConnection *mainConnection = [NSURLConnection connectionWithRequest:urlRequest delegate:self]; if (nil == mainConnection) { NSLog(@"Could not create the NSURLConnection object"); } (void)connection:(NSURLConnection )connection didReceiveResponse:(NSURLResponse)response { self.tabBarController.selectedIndex=1; [receivedData setLength:0]; percent = 0; localFilename = [[[url2 absoluteString] lastPathComponent] copy]; NSLog(localFilename); NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0] ; NSString *appFile = [documentsDirectory stringByAppendingPathComponent:localFilename]; [[NSFileManager defaultManager] createFileAtPath:appFile contents:nil attributes:nil]; [downloadname setHidden:NO]; [downloadname setText:localFilename]; expectedBytes = [response expectedContentLength]; exp = [response expectedContentLength]; NSLog(@"content-length: %lli Bytes", expectedBytes); file = [[NSFileHandle fileHandleForUpdatingAtPath:appFile] retain]; if (file) { [file seekToEndOfFile]; } } (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { if (file) { [file seekToEndOfFile]; } [file writeData:data]; [receivedData appendData:data]; long long resourceLength = [receivedData length]; float res = [receivedData length]; percent = res/exp; [progress setHidden:NO]; [progress setProgress:percent]; NSLog(@"Remaining: %lli KB", (expectedBytes-resourceLength)/1024); [kbleft setHidden:NO]; [kbleft setText:[NSString stringWithFormat:@"%lli / %lli KB", expectedBytes/1024 ,(resourceLength)/1024]]; } in the connectiondidfinish loading i close the file. all working fine for nearly every hoster except hosters wich have a capture procedure before like filedude.com in the uiwebview i can surf to the downloadpage enter the captcha and get the downloadlink. when i click on it the file will be created in the documentsdir with the filename and the download starts but he dont get any data. every file has 0kb and the NSLog(@"content-length: %lli Bytes", expectedBytes); gives out something like 100-400 byte . can somebody help me solve this problem? kind regards
