  • Fonts, goes back to default size

    - by Bladimir Ruiz
    Every time I change the font, it goes back to the default size, which is 12, even if I change it before with the "Tamano" menu, it only goes back to 12 every time, my guess would be the way I change the size with deriveFont(), but don't I now any other way to change it. public static class cambiar extends JFrame { public cambiar() { final Font aryal = new Font("Comic Sans MS", Font.PLAIN, 12); JFrame ventana = new JFrame("Cambios en el Texto!"); JPanel adentro = new JPanel(); final JLabel texto = new JLabel("Texto a Cambiar!"); texto.setFont(aryal); JMenuBar menu = new JMenuBar(); JMenu fuentes = new JMenu("Fuentes"); /* Elementos de Fuentes */ JMenuItem arial = new JMenuItem("Arial"); arial.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { Font arrrial = new Font("Arial", Font.PLAIN, 12); float tam = (float) texto.getFont().getSize(); String hola = String.valueOf(tam); texto.setFont(arrrial); texto.setFont(texto.getFont().deriveFont(tam)); } }); fuentes.add(arial); /* FIN Fuentes */ JMenu tamano = new JMenu("Tamano"); /* Elementos de Tamano */ JMenuItem font13 = new JMenuItem("13"); font13.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { texto.setFont(texto.getFont().deriveFont(23.0f)); } }); JMenuItem font14 = new JMenuItem("14"); arial.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { texto.setFont(aryal); } }); JMenuItem font15 = new JMenuItem("15"); arial.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { texto.setFont(aryal); } }); JMenuItem font16 = new JMenuItem("16"); arial.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { texto.setFont(aryal); } }); JMenuItem font17 = new JMenuItem("17"); arial.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { texto.setFont(aryal); } }); JMenuItem font18 = new JMenuItem("18"); arial.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { texto.setFont(aryal); } }); JMenuItem font19 = new JMenuItem("19"); arial.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { texto.setFont(aryal); } }); JMenuItem font20 = new JMenuItem("20"); arial.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { texto.setFont(aryal); } }); tamano.add(font13); /* FIN tanano */ JMenu tipo = new JMenu("Tipo"); /* Elementos de tipo */ /* FIN tipo */ /* Elementos del JMENU */ menu.add(fuentes); menu.add(tamano); menu.add(tipo); /* FIN JMENU */ /* Elementos del JPanel */ adentro.add(menu); adentro.add(texto); /* FIN JPanel */ /* Elementos del JFRAME */ ventana.add(adentro); ventana.setVisible(true); ventana.setSize(250, 250); /* FIN JFRAME */ } } Thanks in Advance!

  • (Ordered) Set Partitions in fixed-size Blocks

    - by Eugen
    Here is a function I would like to write but am unable to do so. Even if you don't / can't give a solution I would be grateful for tips. For example, I know that there is a correlation between the ordered represantions of the sum of an integer and ordered set partitions but that alone does not help me in finding the solution. So here is the description of the function I need: The Task Create an efficient* function List<int[]> createOrderedPartitions(int n_1, int n_2,..., int n_k) that returns a list of arrays of all set partions of the set {0,...,n_1+n_2+...+n_k-1} in number of arguments blocks of size (in this order) n_1,n_2,...,n_k (e.g. n_1=2, n_2=1, n_3=1 -> ({0,1},{3},{2}),...). Here is a usage example: int[] partition = createOrderedPartitions(2,1,1).get(0); partition[0]; // -> 0 partition[1]; // -> 1 partition[2]; // -> 3 partition[3]; // -> 2 Note that the number of elements in the list is (n_1+n_2+...+n_n choose n_1) * (n_2+n_3+...+n_n choose n_2) * ... * (n_k choose n_k). Also, createOrderedPartitions(1,1,1) would create the permutations of {0,1,2} and thus there would be 3! = 6 elements in the list. * by efficient I mean that you should not initially create a bigger list like all partitions and then filter out results. You should do it directly. Extra Requirements If an argument is 0 treat it as if it was not there, e.g. createOrderedPartitions(2,0,1,1) should yield the same result as createOrderedPartitions(2,1,1). But at least one argument must not be 0. Of course all arguments must be = 0. Remarks The provided pseudo code is quasi Java but the language of the solution doesn't matter. In fact, as long as the solution is fairly general and can be reproduced in other languages it is ideal. Actually, even better would be a return type of List<Tuple<Set>> (e.g. when creating such a function in Python). However, then the arguments wich have a value of 0 must not be ignored. createOrderedPartitions(2,0,2) would then create [({0,1},{},{2,3}),({0,2},{},{1,3}),({0,3},{},{1,2}),({1,2},{},{0,3}),...] Background I need this function to make my mastermind-variation bot more efficient and most of all the code more "beautiful". Take a look at the filterCandidates function in my source code. There are unnecessary / duplicate queries because I'm simply using permutations instead of specifically ordered partitions. Also, I'm just interested in how to write this function. My ideas for (ugly) "solutions" Create the powerset of {0,...,n_1+...+n_k}, filter out the subsets of size n_1, n_2 etc. and create the cartesian product of the n subsets. However this won't actually work because there would be duplicates, e.g. ({1,2},{1})... First choose n_1 of x = {0,...,n_1+n_2+...+n_n-1} and put them in the first set. Then choose n_2 of x without the n_1 chosen elements beforehand and so on. You then get for example ({0,2},{},{1,3},{4}). Of course, every possible combination must be created so ({0,4},{},{1,3},{2}), too, and so on. Seems rather hard to implement but might be possible. Research I guess this goes in the direction I want however I don't see how I can utilize it for my specific scenario. http://rosettacode.org/wiki/Combinations

  • LLVM: Passing a pointer to a struct, which holds a pointer to a function, to a JIT function

    - by Rusky
    I have an LLVM (version 2.7) module with a function that takes a pointer to a struct. That struct contains a function pointer to a C++ function. The module function is going to be JIT-compiled, and I need to build that struct in C++ using the LLVM API. I can't seem get the pointer to the function as an LLVM value, let alone pass a pointer to the ConstantStruct that I can't build. I'm not sure if I'm even on the track, but this is what I have so far: void print(char*); vector<Constant*> functions; functions.push_back(ConstantExpr::getIntToPtr( ConstantInt::get(Type::getInt32Ty(context), (int)print), /* function pointer type here, FunctionType::get(...) doesn't seem to work */ )); ConstantStruct* struct = cast<ConstantStruct>(ConstantStruct::get( cast<StructType>(m->getTypeByName("printer")), functions )); Function* main = m->getFunction("main"); vector<GenericValue> args; args[0].PointerVal = /* not sure what goes here */ ee->runFunction(main, args);

  • Fread binary file dynamic size string [C]

    - by Blackbinary
    I've been working on this assignment, where I need to read in "records" and write them to a file, and then have the ability to read/find them later. On each run of the program, the user can decide to write a new record, or read an old record (either by Name or #) The file is binary, here is its definition: typedef struct{ char * name; char * address; short addressLength, nameLength; int phoneNumber; }employeeRecord; employeeRecord record; The way the program works, it will store the structure, then the name, then the address. Name and address are dynamically allocated, which is why it is necessary to read the structure first to find the size of the name and address, allocate memory for them, then read them into that memory. For debugging purposes I have two programs at the moment. I have my file writing program, and file reading. My actual problem is this, when I read a file I have written, i read in the structure, print out the phone # to make sure it works (which works fine), and then fread the name (now being able to use record.nameLength which reports the proper value too). Fread however, does not return a usable name, it returns blank. I see two problems, either I haven't written the name to the file correctly, or I haven't read it in correctly. Here is how i write to the file: where fp is the file pointer. record.name is a proper value, so is record.nameLength. Also i am writing the name including the null terminator. (e.g. 'Jack\0') fwrite(&record,sizeof record,1,fp); fwrite(record.name,sizeof(char),record.nameLength,fp); fwrite(record.address,sizeof(char),record.addressLength,fp); And i then close the file. here is how i read the file: fp = fopen("employeeRecord","r"); fread(&record,sizeof record,1,fp); printf("Number: %d\n",record.phoneNumber); char *nameString = malloc(sizeof(char)*record.nameLength); printf("\nName Length: %d",record.nameLength); fread(nameString,sizeof(char),record.nameLength,fp); printf("\nName: %s",nameString); Notice there is some debug stuff in there (name length and number, both of which are correct). So i know the file opened properly, and I can use the name length fine. Why then is my output blank, or a newline, or something like that? (The output is just Name: with nothing after it, and program finishes just fine) Thanks for the help.

  • How to give properties to c++ classes (interfaces)

    - by caas
    Hello, I have built several classes (A, B, C...) which perform operations on the same BaseClass. Example: struct BaseClass { int method1(); int method2(); int method3(); } struct A { int methodA(BaseClass& bc) { return bc.method1(); } } struct B { int methodB(BaseClass& bc) { return bc.method2()+bc.method1(); } } struct C { int methodC(BaseClass& bc) { return bc.method3()+bc.method2(); } } But as you can see, each class A, B, C... only uses a subset of the available methods of the BaseClass and I'd like to split the BaseClass into several chunks such that it is clear what it used and what is not. For example a solution could be to use multiple inheritance: // A uses only method1() struct InterfaceA { virtual int method1() = 0; } struct A { int methodA(InterfaceA&); } // B uses method1() and method2() struct InterfaceB { virtual int method1() = 0; virtual int method2() = 0; } struct B { int methodB(InterfaceB&); } // C uses method2() and method3() struct InterfaceC { virtual int method2() = 0; virtual int method3() = 0; } struct C { int methodC(InterfaceC&); } The problem is that each time I add a new type of operation, I need to change the implementation of BaseClass. For example: // D uses method1() and method3() struct InterfaceD { virtual int method1() = 0; virtual int method3() = 0; } struct D { int methodD(InterfaceD&); } struct BaseClass : public A, B, C // here I need to add class D { ... } Do you know a clean way I can do this? Thanks for your help edit: I forgot to mention that it can also be done with templates. But I don't like this solution either because the required interface does not appear explicitly in the code. You have to try to compile the code to verify that all required methods are implemented correctly. Plus, it would require to instantiate different versions of the classes (one for each BaseClass type template parameter) and this is not always possible nor desired.

  • Increase Max Pool Size ERROR when using SYBASE ASE ADO.NET data provider

    - by Brani
    I have made a program in VB.net (visual studio 2003) that connects to a SYBASE ASE database using the ADO.NET data provider. Recently, after a hard disk failure, I restored the program's code from a (rather old) backup. But now the connection fails with a message that does not remind me of anything that I have seen before. Here is the code and the error message: Dim cn As New AseConnection("Data Source='my_server';Port='5000';UID='sa';PWD='my_pwd';Database='my_db';") cn.Open() Error message: Sybase.Data.AseClient.AseException - Cannot allocate more connections. Connection pool is at maximum. Increase Max Pool Size Can anybody help me?

  • iTextSharp custom paper size

    - by Morron
    Hi, I'm using iTextsharp library to create PDF files. I can declare for A4 Landscape paper like this: Dim pdfTable As New PdfPTable(9) pdfTable.WidthPercentage = 100 Dim pdfDoc As New Document(PageSize.A4.Rotate()) I'm wondering how I can set Height of pdfTable or A4 Height manually. Because there's a lot more margin left at the bottom, and I need to put some text at that margin. Right now, I put a line of text at the bottom, the line's got pushed to the new page. Q1: How can I override the height of A4 paper provied by iTextsharp? Q2: How can I create a custom size paper, say Width = 29cm, Height = 22cm? Thank you.

  • self.view.frame.size in viewDidLoad and didRotateFromInterfaceOrientation are different

    - by tokentoken
    I created iphone view-based project, and added UINavigationController by code. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { TestViewController *vc = [[TestViewController alloc]init]; navController = [[UINavigationController alloc]initWithRootViewController:vc]; [window addSubview:navController.view]; [window makeKeyAndVisible]; return YES; } After that, I checked self.view.frame.size.height in viewDidLoad and didRotateFromInterfaceOrientation, and they're different. (they're 460 and 416) I suppose the height of NavigationBar is not included in viewDidLoad, but should I add it manually (add 44)?

  • PHP, ImageMagick, Google's Page Speed, & JPG File Size Optimization

    - by Sonny
    I have photo gallery code that does image re-sizing and thumbnail creation. I use ImageMagick to do this. I ran a gallery page through Google's Page Speed tool and it revealed that the re-sized images and thumbnails both have about an extra 10KB of data (JPEG files specifically). What can I add to my scripts to optimize the file size? ADDITIONAL INFORMATION I am using the imagick::FILTER_LANCZOS filter with a blur setting of 0.9 when calling the resizeImage() function. JPEGs have a quality setting of 80.

  • Delphi Pascal - Using SetFilePointerEx and GetFileSizeEx, Getting Physical Media exact size when reading as a file

    - by SuicideClutchX2
    I am having trouble understanding how to delcare GetFileSizeEx and SetFilePointerEx in Delphi 2009 so that I can use them since they are not in the RTL or Windows.pas. I was able to compile with the following: function GetFileSizeEx(hFile: THandle; lpFileSizeHigh: Pointer): DWORD; external 'kernel32'; Then using GetFileSizeEx(PD, Pointer(DriveSize)); to get the size. But could not get it to work, the disk handle I am using is valid and I have had no problem reading the data or working under the 2gb mark with the older API's. GetFileSize of course returns 4294967295. I have had greater trouble trying to use SetFilePointerEx with the data types it uses. The overall project needs to read the data from a flash card, which is not a problem at all I can do this. My problem is that I can not find the length or size of the media I will be reading. I have code I have used in the past to do this with media under 2GB. But now that I need to read media over 2GB it is a problem. If you still dont understand I am dumping a card with all data including the boot record, etc. This is the code I would normally use to read from the physical disk to grab say the boot record and dump it to file: SetFilePointer(PD,0,nil,FILE_BEGIN); SetLength(Buffer,512); ReadFile(PD,Buffer[0],512,BytesReturned,nil); I just need to figure out how to find the end of an 8gb card and so on as well as being able to set a file pointer beyond the 2gb barrier. I guess any help in the external declarations as well as understand the values that SetFilePointerEx uses (I do not understand the whole High Low thing) would be of great help. var Form1: TForm1; function GetFileSizeEx(hFile: THandle; var FileSize: Int64): DWORD; stdcall; external 'kernel32'; implementation {$R *.dfm} function GetLD(Drive: Char): Cardinal; var Buffer : String; begin Buffer := Format('\\.\%s:',[Drive]); Result := CreateFile(PChar(Buffer),GENERIC_READ Or GENERIC_WRITE,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); If Result = INVALID_HANDLE_VALUE Then begin Result := CreateFile(PChar(Buffer),GENERIC_READ,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); end; end; function GetPD(Drive: Byte): Cardinal; var Buffer : String; begin If Drive = 0 Then begin Result := INVALID_HANDLE_VALUE; Exit; end; Buffer := Format('\\.\PHYSICALDRIVE%d',[Drive]); Result := CreateFile(PChar(Buffer),GENERIC_READ Or GENERIC_WRITE,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); If Result = INVALID_HANDLE_VALUE Then begin Result := CreateFile(PChar(Buffer),GENERIC_READ,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); end; end; function GetPhysicalDiskNumber(Drive: Char): Byte; var LD : DWORD; DiskExtents : PVolumeDiskExtents; DiskExtent : TDiskExtent; BytesReturned : Cardinal; begin Result := 0; LD := GetLD(Drive); If LD = INVALID_HANDLE_VALUE Then Exit; Try DiskExtents := AllocMem(Max_Path); DeviceIOControl(LD,IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS,nil,0,DiskExtents,Max_Path,BytesReturned,nil); If DiskExtents^.NumberOfDiskExtents > 0 Then begin DiskExtent := DiskExtents^.Extents[0]; Result := DiskExtent.DiskNumber; end; Finally CloseHandle(LD); end; end; procedure TForm1.Button1Click(Sender: TObject); var PD : DWORD; BytesReturned : Cardinal; Buffer : Array Of Byte; myFile: File; DriveSize: Int64; begin PD := GetPD(GetPhysicalDiskNumber(Edit1.Text[1])); If PD = INVALID_HANDLE_VALUE Then Exit; Try GetFileSizeEx(PD, DriveSize); //SetFilePointer(PD,0,nil,FILE_BEGIN); //etLength(Buffer,512); //ZeroMemory(@Buffer,SizeOf(Buffer)); //ReadFile(PD,Buffer[0],512,BytesReturned,nil); //AssignFile(myFile, 'StickDump.bin'); //ReWrite(myFile, 512); //BlockWrite(myFile, Buffer[0], 1); //CloseFile(myFile); Finally CloseHandle(PD); End; end;

  • Display custom error page when file upload exceeds allowed size in ASP.NET MVC2

    - by Marcus
    Hello! My main issue is that I want to display an custom error page when an uploaded file exceeds allowed size (maxRequestLength in web.config). When the big file is uploaded an HttpException is thrown before my upload action method in the controller is invoked. This is expected. I have tried to catch the exception in a custom attribute and also to override OnException in the controller. Why isnt it possible to catch the exception in either the attribute or the OnException method? Its possible though to catch the exception in Application_Error in global.asax but neither Response.Redirect nor Server.Transfer works for redirecting to the custom error page. Server.Transfer gives the "failed to process child request" error and response.redirect gives the "Http headers already sent" error. Any ideas? Thanks in advance! Marcus

  • Size of static libraries generated by XCode

    - by shaft80
    I have a project tree in XCode that looks like this: AppProject depends on ObjcWrapper that in turn depends on PureCppLib. ObjcWrapper and PureCppLib are static library projects. Combined, all sources barely reach 15k lines of code, and, as expected, the size of resulting binary is about 750Kb in release mode and slightly over 1Mb in debug mode. So far, so good. However, ObjcWraper.a and PureCppLib.a are over 6Mb each in either mode. So the first question is why it is so. But more importantly, how can I ensure that those static libs do not include parts or all of the source code? Thanks in advance!

  • iphone - calculating the font size

    - by Mike
    I have to show a label with font size = 14 when the view is 480x320. Supposing I would like to do this in a way that my code will be working well for all future device's screen sizes, including iPad and others following (I am sure more will come), what is the best way to do that? I could do this proportionally, I mean, if the scale increased X, increase the fonts X, but my concern is the different aspect ratios of the devices. The iPhone aspect ratio is 1.5, but iPad's is 1.33, and other aspect ratios can come... I am not sure if this simple scale method will be enough to produce font consistency across all devices. Any suggestions? thanks for any help.

  • Decoding bitmaps in Android with the right size

    - by hgpc
    I decode bitmaps from the SD card using BitmapFactory.decodeFile. Sometimes the bitmaps are bigger than what the application needs or that the heap allows, so I use BitmapFactory.Options.inSampleSize to request a subsampled (smaller) bitmap. The problem is that the platform does not enforce the exact value of inSampleSize, and I sometimes end up with a bitmap either too small, or still too big for the available memory. From http://developer.android.com/reference/android/graphics/BitmapFactory.Options.html#inSampleSize: Note: the decoder will try to fulfill this request, but the resulting bitmap may have different dimensions that precisely what has been requested. Also, powers of 2 are often faster/easier for the decoder to honor. How should I decode bitmaps from the SD card to get a bitmap of the exact size I need while consuming as little memory as possible to decode it?

  • Virtual Earth / Bing maps javascript file size

    - by Aquinas
    I am working with a site that uses virtual earth for its mapping. Unfortunately the file size of the referenced javascript file, ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2, is 200 something kb before being expanded (to 970kb). As our site runs under https this file is not cached on the client, and can cause a few seconds delay to users, made more substantial in times of high load. My question is, is there anyway to get virtual earth to run smaller, or have more efficient lazy loading? At the moment it looks like our hands are tied.

  • UITableViewCellStyleDefault image size

    - by Rob Bonner
    Hello all, I am getting some odd behavior from stock table cells, or maybe not odd, maybe I am making some assumptions. I create the cells as follows: cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; Then I assign an image to the default imageView property. My image usually comes in from a user, so it might be larger than the default size. To take care of this I: [cell.imageView setContentMode:UIViewContentModeScaleAspectFit]; which I expected to scale the image for me within the control, but in reality, the images are all over the map. So, is there a proper way to constrain the image in stock cell types? Thanks in advance!

  • Java printf using variable field size?

    - by paxdiablo
    I'm just trying to convert some C code over to Java and I'm having a little trouble with String.printf. In C, to get a specific width based on a variable, I can use: printf("Current index = %*d\n", sz, index); and it will format the integer to be a specific size based on sz. Trying: System.out.println(String.format("Current index = %*d\n", sz, index)); results in an error since it doesn't like the *. I currently have the following kludge: System.out.println(String.format("Current index = %" + sz + "d\n", index)); but I'm hoping there's a slightly better way, yes?

  • Animating a font size change in a UITableView

    Hey Simple little app for educational purposes, its a simple uitableview and I want users to be able to use a uislider to adjust the font size as needed. The code I have now works to change the font but only when the view is updated, ie when i pull up or down the table view to reveal other cells. I'd like the font change to be reflected immediately as a user moves the uislider if possible, here's the code that I have working half way: -(UITableViewCell *) tableView: (UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *) indexPath { static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier]; if (cell == nil) cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier: SimpleTableIdentifier] autorelease]; NSUInteger row = [indexPath row]; cell.text = [listData objectAtIndex:row]; UIImage *image = [UIImage imageNamed:@"star.png"]; cell.font = [UIFont systemFontOfSize:[fontSlider value]]; cell.image = image; return cell; }

  • OpenGL ES canvas size

    - by Chaoz
    Ahoy, I'm working on an OpenGL ES based game for Android using the NDK. My application is targeted towards SDK 1.6 and above. I seem to be having a problem creating a canvas of the phones native size. My rendering is done through a native gameloop that uses OpenGL 1.0. I'm using the emulator and that gives me a 480x320 canvas -- this is totally fine. Then, when I run the same application on my HTC Desire which has a native resolution of 800x480 I'm getting a canvas of 533x320. Anyone have any information on how to deal with/solve this? Any other information about this is also appreciated. Thanks in advance!

    I am building a Google App Engine App that lets users upload images; I have everything working fine, but I am struggling to find a way to ensure that the user does not upload an image too large (because I am resizing the images, so this crashes my python script). When a user uploads a large image, I get this error RequestTooLargeError: The request to API call images.Transform() was too large. I know that there is a size limitation on what GAE allows for it's image API, I am just trying to find a way to deal with this server side; something along the lines of if (image is too large): inform user else: proceed I haven't had any luck finding the right python code to do this; can anyone help me out?

    - by alessandro ferrucci
    Hello, I have a test table. The test table is as follows: CREATE TABLE mytest ( num1 int(10) unsigned NOT NULL, KEY key1 (num1) ) ENGINE=MyISAM DEFAULT CHARSET=latin1; I inserted 50 million rows in this table. When I do show table status the avg_row_length is 7. I was expecting to see 4 since mySQL uses 4 bytes for integers. Does the key have an effect on the avg_row_length? When I look at my .MYD file the size is 334 MB which is exactly what it should be given that the avg_row_length is 7, however I was really expecting to see 190 MB given that I only have an int. +----------------+--------+---------+------------+----------+----------------+-------------+------------------+--------------+-----------+----------------+---------------------+---------------------+------------+-------------------+----------+----------------+---------+ | Name | Engine | Version | Row_format | Rows | Avg_row_length | Data_length | Max_data_length | Index_length | Data_free | Auto_increment | Create_time | Update_time | Check_time | Collation | Checksum | Create_options | Comment | +----------------+--------+---------+------------+----------+----------------+-------------+------------------+--------------+-----------+----------------+---------------------+---------------------+------------+-------------------+----------+----------------+---------+ | mytest | MyISAM | 10 | Fixed | 50000000 | 7 | 350000000 | 1970324836974591 | 600518656 | 0 | NULL | 2010-05-22 09:15:06 | 2010-05-22 19:32:53 | NULL | latin1_swedish_ci | NULL | | | I have included the output of show table status for mytest table. Sorry about the formatting :D Thanks in advance! Alessandro Ferrucci
