    i've tested my site on 2 phone models using the 'generic' browser that came with the phone, but sadly, everytime I tried to login, it will return me back to my index page. here's my login code <form name='login' method='POST' action='authentication.php'> <table border=0 cellpadding=2> <tr><td>Login:</td><td></td></tr> <tr><td>E-mail: </td><td><input type=text name='email' id='email' size=20 maxlength="200"></td></tr> <tr><td>Password: </td><td><input type=password name='password' id='password' size=20 maxlength="100"></td></tr> <tr><td></td><td><input type=submit value='Login'></td></tr> </table></form> and here's the authentication.php (snippet) $currentUserEmail = $_POST["email"]; $currentUserPwd = md5($_POST["password"]); $stmt = $dbi->prepare("select status from users where email=? and pwd=?"); $stmt->bind_param('ss', $currentUserEmail,$currentUserPwd); mysqli_stmt_execute($stmt); mysqli_stmt_store_result($stmt); $isUserAvailable = mysqli_stmt_num_rows($stmt); $stmt->bind_result($getUserStatus); $stmt->execute() or die (mysqli_error()); $stmt->store_result(); $stmt->fetch(); $stmt->close(); if($isUserAvailable > 0){ if ($getUserStatus == "PENDING") { $userIsLoggedIn = "NO"; $registeredUser = "NO"; unset($userIsLoggedIn); setcookie("currentMobileUserName", "", time()-3600); setcookie("currentMobileUserEmail", "", time()-3600); setcookie("currentMobileSessionID", "", time()-3600); setcookie("currentMobileUID", "", time()-3600); header('Location: '.$config['MOBILE_URL'].'/index.php?error=2&email='.$currentUserEmail); }elseif (($getUserStatus == "ACTIVE") || ($getUserStatus == "active")){ //means successfully logged in //set the cookie setcookie("currentMobileUserName", $currentUserName, $expire); setcookie("currentMobileUserEmail", $currentUserEmail, $expire); setcookie("currentMobileSessionID", $getGeneratedMobileUSID, $expire); setcookie("currentMobileUID", $currentUID, $expire); $userIsLoggedIn = "YES"; $registeredUser = "YES"; $result = $stmt->execute() or die (mysqli_error($dbi)); if ($caller == "indexLoginForm"){ header('Location: '.$config['MOBILE_URL'].'/home.php'); }else{ header('Location: '.$config['MOBILE_URL'].'/home.php'); } } }else{ $userIsLoggedIn = "NO"; $registeredUser = "NO"; unset($userIsLoggedIn); setcookie("currentMobileUserName", "", time()-3600); setcookie("currentMobileUserEmail", "", time()-3600); setcookie("currentMobileSessionID", "", time()-3600); setcookie("currentMobileUID", "", time()-3600); header('Location: '.$config['MOBILE_URL'].'/index.php?error=1'); } The only way I can access my mobile site is by using opera mini. Just FYI, both the 'generic browsers' i tested my site with supports cookie (at least this is what the browser settings said). thanks

    Hi. I'm a Delphi programmer. I want to mount all partitions from USB drives in Windows (XP). The OS is doing this automatically but there are situations when such a program is useful. I know how to find if a drive is on USB or not. My code so far is: type STORAGE_QUERY_TYPE = (PropertyStandardQuery = 0, PropertyExistsQuery, PropertyMaskQuery, PropertyQueryMaxDefined); TStorageQueryType = STORAGE_QUERY_TYPE; STORAGE_PROPERTY_ID = (StorageDeviceProperty = 0, StorageAdapterProperty); TStoragePropertyID = STORAGE_PROPERTY_ID; STORAGE_PROPERTY_QUERY = packed record PropertyId: STORAGE_PROPERTY_ID; QueryType: STORAGE_QUERY_TYPE; AdditionalParameters: array[0..9] of AnsiChar; end; TStoragePropertyQuery = STORAGE_PROPERTY_QUERY; STORAGE_BUS_TYPE = (BusTypeUnknown = 0, BusTypeScsi, BusTypeAtapi, BusTypeAta, BusType1394, BusTypeSsa, BusTypeFibre, BusTypeUsb, BusTypeRAID, BusTypeiScsi, BusTypeSas, BusTypeSata, BusTypeMaxReserved = $7F); TStorageBusType = STORAGE_BUS_TYPE; STORAGE_DEVICE_DESCRIPTOR = packed record Version: DWORD; Size: DWORD; DeviceType: Byte; DeviceTypeModifier: Byte; RemovableMedia: Boolean; CommandQueueing: Boolean; VendorIdOffset: DWORD; ProductIdOffset: DWORD; ProductRevisionOffset: DWORD; SerialNumberOffset: DWORD; BusType: STORAGE_BUS_TYPE; RawPropertiesLength: DWORD; RawDeviceProperties: array[0..0] of AnsiChar; end; TStorageDeviceDescriptor = STORAGE_DEVICE_DESCRIPTOR; const IOCTL_STORAGE_QUERY_PROPERTY = $002D1400; var i: Integer; H: THandle; USBDrives: array of Byte; Query: TStoragePropertyQuery; dwBytesReturned: DWORD; Buffer: array[0..1023] of Byte; sdd: TStorageDeviceDescriptor absolute Buffer; begin SetLength(UsbDrives, 0); SetErrorMode(SEM_FAILCRITICALERRORS); for i := 0 to 99 do begin H := CreateFile(PChar('\\.\PhysicalDrive' + IntToStr(i)), 0, FILE_SHARE_READ or FILE_SHARE_WRITE, nil, OPEN_EXISTING, 0, 0); if H <> INVALID_HANDLE_VALUE then begin try dwBytesReturned := 0; FillChar(Query, SizeOf(Query), 0); FillChar(Buffer, SizeOf(Buffer), 0); sdd.Size := SizeOf(Buffer); Query.PropertyId := StorageDeviceProperty; Query.QueryType := PropertyStandardQuery; if DeviceIoControl(H, IOCTL_STORAGE_QUERY_PROPERTY, @Query, SizeOf(Query), @Buffer, SizeOf(Buffer), dwBytesReturned, nil) then if sdd.BusType = BusTypeUsb then begin SetLength(USBDrives, Length(USBDrives) + 1); UsbDrives[High(USBDrives)] := Byte(i); end; finally CloseHandle(H); end; end; end; for i := 0 to High(USBDrives) do begin // end; end. But I don't know how to access partitions on each drive and mounts them. Can you please help me? I searched before I asked and I couldn't find a working code. But if I did not properly then I'm sorry and please show me that topic. Best regards, John

  • Right-aligning button in a grid with possibly no content - stretch grid to always fill the page

    - by Peter Perhác
    Hello people, I am losing my patience with this. I am working on a Windows Phone 7 application and I can't figure out what layout manager to use to achieve the following: Basically, when I use a Grid as the layout root, I can't make the grid to stretch to the size of the phone application page. When the main content area is full, all is well and the button sits where I want it to sit. However, in case the page content is very short, the grid is only as wide as to accommodate its content and then the button (which I am desperate to keep near the right edge of the screen) moves away from the right edge. If I replace the grid and use a vertically oriented stack panel for the layout root, the button sits where I want it but then the content area is capable of growing beyond the bottom edge. So, when I place a listbox full of items into the main content area, it doesn't adjust its height to be completely in view, but the majority of items in that listbox are just rendered below the bottom edge of the display area. I have tried using a third-party DockPanel layout manager and then docked the button in it's top section and set the button's HorizontalAlignment="Right" but the result was the same as with the grid, it also shrinks in size when there isn't enough content in the content area (or when title is short). How do I do this then? ==EDIT== I tried WPCoder's XAML, only I replaced the dummy text box with what I would have in a real page (stackpanel) and placed a listbox into the ContentPanel grid. I noticed that what I had before and what WPCoder is suggesting is very similar. Here's my current XAML and the page still doesn't grow to fit the width of the page and I get identical results to what I had before: <phone:PhoneApplicationPage x:Name="categoriesPage" x:Class="CatalogueBrowser.CategoriesPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone" xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" FontFamily="{StaticResource PhoneFontFamilyNormal}" FontSize="{StaticResource PhoneFontSizeNormal}" Foreground="{StaticResource PhoneForegroundBrush}" SupportedOrientations="PortraitOrLandscape" Orientation="Portrait" mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768" xmlns:ctrls="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit" shell:SystemTray.IsVisible="True"> <Grid x:Name="LayoutRoot" Background="Transparent"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <StackPanel Orientation="Horizontal" VerticalAlignment="Center" > <TextBlock Text="Browsing:" Margin="10,10" Style="{StaticResource PhoneTextTitle3Style}" /> <TextBlock x:Name="ListTitle" Text="{Binding DisplayName}" Margin="0,10" Style="{StaticResource PhoneTextTitle3Style}" /> </StackPanel> <Button Grid.Column="1" x:Name="btnRefineSearch" Content="Refine Search" Style="{StaticResource buttonBarStyle}" FontSize="14" /> </Grid> <Grid x:Name="ContentPanel" Grid.Row="1"> <ListBox x:Name="CategoryList" ItemsSource="{Binding Categories}" Style="{StaticResource CatalogueList}" SelectionChanged="CategoryList_SelectionChanged"/> </Grid> </Grid> </phone:PhoneApplicationPage> This is what the page with the above XAML markup looks like in the emulator:

  • Problem using delete[] (Heap corruption) when implementing operator+= (C++)

    - by Darel
    I've been trying to figure this out for hours now, and I'm at my wit's end. I would surely appreciate it if someone could tell me when I'm doing wrong. I have written a simple class to emulate basic functionality of strings. The class's members include a character pointer data (which points to a dynamically created char array) and an integer strSize (which holds the length of the string, sans terminator.) Since I'm using new and delete, I've implemented the copy constructor and destructor. My problem occurs when I try to implement the operator+=. The LHS object builds the new string correctly - I can even print it using cout - but the problem comes when I try to deallocate the data pointer in the destructor: I get a "Heap Corruption Detected after normal block" at the memory address pointed to by the data array the destructor is trying to deallocate. Here's my complete class and test program: #include <iostream> using namespace std; // Class to emulate string class Str { public: // Default constructor Str(): data(0), strSize(0) { } // Constructor from string literal Str(const char* cp) { data = new char[strlen(cp) + 1]; char *p = data; const char* q = cp; while (*q) *p++ = *q++; *p = '\0'; strSize = strlen(cp); } Str& operator+=(const Str& rhs) { // create new dynamic memory to hold concatenated string char* str = new char[strSize + rhs.strSize + 1]; char* p = str; // new data char* i = data; // old data const char* q = rhs.data; // data to append // append old string to new string in new dynamic memory while (*p++ = *i++) ; p--; while (*p++ = *q++) ; *p = '\0'; // assign new values to data and strSize delete[] data; data = str; strSize += rhs.strSize; return *this; } // Copy constructor Str(const Str& s) { data = new char[s.strSize + 1]; char *p = data; char *q = s.data; while (*q) *p++ = *q++; *p = '\0'; strSize = s.strSize; } // destructor ~Str() { delete[] data; } const char& operator[](int i) const { return data[i]; } int size() const { return strSize; } private: char *data; int strSize; }; ostream& operator<<(ostream& os, const Str& s) { for (int i = 0; i != s.size(); ++i) os << s[i]; return os; } // Test constructor, copy constructor, and += operator int main() { Str s = "hello"; // destructor for s works ok Str x = s; // destructor for x works ok s += "world!"; // destructor for s gives error cout << s << endl; cout << x << endl; return 0; }

  • Reducing lag when downloading large amount of data from webpage

    - by Mahir
    I am getting data via RSS feeds and displaying each article in a table view cell. Each cell has an image view, set to a default image. If the page has an image, the image is to be replaced with the image from the article. As of now, each cell downloads the source code from the web page, causing the app to lag when I push the view controller and when I try scrolling. Here is what I have in the cellForRowAtIndexPath: method. NSString * storyLink = [[stories objectAtIndex: storyIndex] objectForKey: @"link"]; storyLink = [storyLink stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; NSString *sourceCode = [NSString stringWithContentsOfURL:[NSURL URLWithString:storyLink] encoding:NSUTF8StringEncoding error:&error]; NSString *startPt = @"instant-gallery"; NSString *startPt2 = @"<img src=\""; if ([sourceCode rangeOfString:startPt].length != 0) { //webpage has images // find the first "<img src=...>" tag starting from "instant-gallery" NSString *trimmedSource = [sourceCode substringFromIndex:NSMaxRange([sourceCode rangeOfString:startPt])]; trimmedSource = [trimmedSource substringFromIndex:NSMaxRange([trimmedSource rangeOfString:startPt2])]; trimmedSource = [trimmedSource substringToIndex:[trimmedSource rangeOfString:@"\""].location]; NSURL *url = [NSURL URLWithString:trimmedSource]; NSData *data = [NSData dataWithContentsOfURL:url]; UIImage *image = [UIImage imageWithData:data]; cell.picture.image = image; Someone suggested using NSOperationQueue. Would this way be a good solution? EDIT: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *MyIdentifier = @"FeedCell"; LMU_LAL_FeedCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"LMU_LAL_FeedCell" owner:self options:nil]; cell = (LMU_LAL_FeedCell*) [nib objectAtIndex:0]; } int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1]; NSString *untrimmedTitle = [[stories objectAtIndex: storyIndex] objectForKey: @"title"]; cell.title.text = [untrimmedTitle stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]; CGSize maximumLabelSize = CGSizeMake(205,9999); CGSize expectedLabelSize = [cell.title.text sizeWithFont:cell.title.font constrainedToSize:maximumLabelSize]; //adjust the label to the the new height.

  • Select dropdown with fixed width cutting off content in IE

    - by aaandre
    The issue: Some of the items in the select require more than the specified width of 145px in order to display fully. Firefox behavior: clicking on the select reveals the dropdown elements list adjusted to the width of the longest element. IE6 & IE7 behavior: clicking on the select reveals the dropdown elements list restricted to 145px width making it impossible to read the longer elements. The current UI requires us to fit this dropdown in 145px and have it host items with longer descriptions. Any advise on resolving the issue with IE? The top element should remain 145px wide even when the list is expanded. Thank you! The css: select.center_pull { background:#eeeeee none repeat scroll 0 0; border:1px solid #7E7E7E; color:#333333; font-size:12px; margin-bottom:4px; margin-right:4px; margin-top:4px; width:145px; } Here's the select input code (there's no definition for the backend_dropbox style at this time) <select id="select_1" class="center_pull backend_dropbox" name="select_1"> <option value="-1" selected="selected">Browse options</option> <option value="-1">------------------------------------</option> <option value="224">Option 1</option> <option value="234">Longer title for option 2</option> <option value="242">Very long and extensively descriptive title for option 3</option> </select> Full html page in case you want to quickly test in a browser: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>dropdown test</title> <style type="text/css"> <!-- select.center_pull { background:#eeeeee none repeat scroll 0 0; border:1px solid #7E7E7E; color:#333333; font-size:12px; margin-bottom:4px; margin-right:4px; margin-top:4px; width:145px; } --> </style> </head> <body> <p>Select width test</p> <form id="form1" name="form1" method="post" action=""> <select id="select_1" class="center_pull backend_dropbox" name="select_1"> <option value="-1" selected="selected">Browse options</option> <option value="-1">------------------------------------</option> <option value="224">Option 1</option> <option value="234">Longer title for option 2</option> <option value="242">Very long and extensively descriptive title for option 3</option> </select> </form> </body> </html>

  • C++ - getline() keeps reading the same line over and over again for some reason

    - by Jammanuser
    I am wondering WTF my while loop which calls istream& getline ( istream& is, string& str ); keeps reading the same line again. I have the following while loop (nested down several levels of other while loops and if statements) which calls getline, but my output statement which is the first code line in the while loop's block of code tells me it is reading the same line over and over again, which explains why my output file doesn't contain the right data when my program is finished. while (getline(file_handle, buffer_str)) { cout<< buffer_str <<endl; cin.get(); if ((buffer_str.find(';', 0) != string::npos) && (buffer_str.find('\"', 0) != string::npos)) { //we're now at the end of the 'exc' initialiation statement buffer_str.erase(buffer_str.size() - 2, 1); buffer_str += '\n'; for (size_t i = 0; i < pos; i++) { buffer_str += ' '; } buffer_str += "throw(exc);\n"; for (size_t i = 0; i < (pos - 3); i++) { buffer_str += ' '; } buffer_str += '}'; } else if (buffer_str.find(search_str6, 0) != string::npos) { //we're now at the second problem line of the first case buffer_str += " {\n"; output_str += buffer_str; output_str += '\n'; getline(file_handle, buffer_str); //We're now at the beginning of the 'exc' initialiation statement output_str += buffer_str; output_str += '\n'; while (getline(file_handle, buffer_str)) { if ((buffer_str.find(';', 0) != string::npos) && (buffer_str.find('\"', 0) != string::npos)) { //we're now at the end of the 'exc' initialiation statement buffer_str.erase(buffer_str.size() - 2, 1); buffer_str += '\n'; for (size_t i = 0; i < pos; i++) { buffer_str += ' '; } buffer_str += "throw(exc);\n"; for (size_t i = 0; i < (pos - 3); i++) { buffer_str += ' '; } buffer_str += '}'; } output_str += buffer_str; output_str += '\n'; if (buffer_str.find("return", 0) != string::npos) { getline(file_handle, buffer_str); output_str += buffer_str; output_str += '\n'; about_to_break = true; break; //out of this while loop } } } if (about_to_break) { break; //out of the level 3 while loop (execution then goes back up to beginning of level 2 while loop) } output_str += buffer_str; output_str += '\n'; } Because of this problem, my if statement and then my else statement in my loop are not functioning as they should, and it doesn't break out of that loop when it should (though it eventually does break out of it, but I don't know exactly how yet). Anyone have any idea what could be causing this problem?? Thanks in advance.

  • c++ protected pointer member to the same class and access privileges

    - by aajmakin
    Hi, Example code is included at the bottom of the message. I'm puzzled about the protected access specifier in a class. I have define a class node which has a protected string member name string name; and a vector of node pointers vector args; Before I thought that a member function of node could not do args[0]-name but a program that does just this does compile and run. However, now I would like to inherit this class and access the name field in one of the args array pointers from this derived class args[0]-name but this does not compile. When I compile the example code below with the commented sections uncommented, the compiler reports: Compiler output: g++ test.cc -o test test.cc: In member function 'void foo::newnode::print_args2()': test.cc:22: error: 'std::string foo::node::name' is protected test.cc:61: error: within this context Compilation exited abnormally with code 1 at Thu Jun 17 12:40:12 Questions: Why can I access the name field of the node pointers in args in class node, because this is what I would excpect from a similarly defined private field in Java. How can I access those fields from the derived class. Example code: #include <iostream> #include <vector> using namespace std; namespace foo { class node; typedef std::vector<node*> nodes; class node { public: node (string _name); void print_args (); void add_node (node* a); protected: nodes args; string name; }; } foo::node::node (string _name) : args(0) { name = _name; } void foo::node::add_node (node* a) { args.push_back(a); } void foo::node::print_args () { for (int i = 0; i < args.size(); i++) { cout << "node " << i << ": " << args[i]->name << endl; } } // namespace foo // { // class newnode : public node // { // public: // newnode (string _name) : node(_name) {} // void print_args2 (); // protected: // }; // } // void foo::newnode::print_args2 () // { // for (int i = 0; i < args.size(); i++) // { // cout << "node " << i << ": " << args[i]->name << endl; // } // } int main (int argc, char** argv) { foo::node a ("a"); foo::node b ("b"); foo::node c ("c"); a.add_node (&b); a.add_node (&c); a.print_args (); // foo::newnode newa ("newa"); // foo::newnode newb ("newb"); // foo::newnode newc ("newc"); // newa.add_node (&newb); // newa.add_node (&newc); // newa.print_args2 (); return 0; }

  • Why does jQuery's $().each() function seem to be losing track of the DOM?

    - by Nate Wagar
    I've recently started encountering a very strange problem. To be honest, I'm not entirely sure how to describe it other than to just show it. Here's the relevant HTML: <div class="component container w100 noEdit" id="contentWrapper"> <div class="component container w50" id="container1"> <div class="component text w50" id="text1"> Text1 </div> </div> <div class="component container w25" id="container2"> Container2 </div> <div class="component container w25" id="container3"> Container3 </div> <div class="component container w25" id="container4"> Container4 </div> </div> And the relevant JavaScript: $(document).ready(function () { //Add the Grab Bar to container components on the page. $('.component').each(wrapComponentForEdit); $('#contentWrapper').sortable(); $('#contentWrapper').disableSelection(); }); var wrapComponentForEdit = function() { if (!$(this).hasClass('noEdit')) { $(this).html('<div class="componentBorder">' + $(this).html() + '</div>'); $(this).prepend('<div class="grabBar_l"><div class="grabBar_r"><div class="grabBar"></div></div></div>'); alert($(this).attr('id')); } } The end result of this is that I see an alert pop up for container1, text1, container2, container3, container 4. And yet only the containers (not the text) end up with the visual changes that the $().each() is supposed to make. Anyone have any idea what the heck is going on? Thanks! EDIT - A different way to do it, that still fails I tried this, with the same result: $(document).ready(function () { //Add the Grab Bar to container components on the page. var matched = $('.component'); var componentCount = $(matched).size(); for (i = 0; i < componentCount; i++) { wrapComponentForEdit($(matched).eq(i)); } $('#contentWrapper').sortable({ handle: '.grabBarBit', tolerance: 'pointer'}); $('#contentWrapper').disableSelection(); }); var wrapComponentForEdit = function(component) { if (!$(component).hasClass('noEdit')) { $(component).html('<div class="grabBar_l grabBarBit"><div class="grabBar_r grabBarBit"><div class="grabBar grabBarBit"></div></div></div><div class="componentBorder">' + $(component).html() + '</div>'); alert($(component).attr('id')); } } EDIT 2: Another alternate method, but this one works I tried another way of doing things, and this way it works. However, the initial question still stands. Judging by how this new way works, it seems to me that the DOM is being updated, but jQuery isn't updating with it, so it loses track of the child element. $(document).ready(function () { //Add the Grab Bar to container components on the page. var componentCount = $('.component').size(); for (i = 0; i < componentCount; i++) { wrapComponentForEdit($('.component').eq(i)); } $('#contentWrapper').sortable({ handle: '.grabBarBit', tolerance: 'pointer'}); $('#contentWrapper').disableSelection(); }); var wrapComponentForEdit = function(component) { if (!$(component).hasClass('noEdit')) { $(component).html('<div class="grabBar_l grabBarBit"><div class="grabBar_r grabBarBit"><div class="grabBar grabBarBit"></div></div></div><div class="componentBorder">' + $(component).html() + '</div>'); alert($(component).attr('id')); } }

  • complex css image centering help?

    - by Tenshiko
    My problem is a bit more complex than the title says. Sorry, I don't know how to be more specific... I'm working on a website and I came across a part where I should display some thumbnails. The thing is, the thumbnails are not matching in dimensions. (I know, it sounds ridiculous, since this is thumbnails are for, right?) No, there is simply NO WAY to create them in the same dimensions!! I've managed to create a HTML+CSS structure to fix this problem, and the images are not stretching to fit their containers if they are smaller while keeping their aspect ratio. The only issue remaining, is to center the images. Since setting margin to "0 auto" or "auto 0" are not helping, I've tried setting up multiple containers and setting the margins to position the images. This is also not working: if I put a 120x120 picture in a 120x80 inner container, and I set the container's top and left margin to -50%, the margins become -60px both. Can this be fixed? Or is there yet another way to center images? I'm open to any suggestions! HTML: <div id="roll"> <div class="imgfix"> <div class="outer"> <div class="inner"> @if (ImageDimensionHelper.WhereToAlignImg(item.Width, item.Height, 120, 82) == ImgAlign.Width) <!-- ImageDimensionHelper tells me if the image should fit the container with its width or height. I set the class of the img accordingly. --> { <img class="width" src="@Url.Content(item.URL)" alt="@item.Name"/> } else { <img class="height" src="@Url.Content(item.URL)" alt="@item.Name"/> } </div> </div> </div> </div> CSS: .imgfix{ overflow:hidden; } .imgfix .outer { width:100%; height:100%;} .imgfix .inner { width:100%; height:100%; margin-top:-50%; margin-left:-50%; } /*This div (.inner) gets -60px for both margins every time, regardless of the size of itself, or the image inside it*/ #roll .imgfix { width:120px; height:82px; border: 1px #5b91ba solid; } #roll .imgfix .outer { margin-top:41px; margin-left:60px; } /*since I know specificly what these margins should be, I set them explicitly, because 50% got the wrong size.*/ #roll .imgfix img.width { width:120px; height:auto; margin: auto 0; } #roll .imgfix img.height { height:82px; width:auto; margin: 0 auto; }

  • Space Between Table Rows

    - by AGoodDisplayName
    This should be a simple problem, but I am have a tough time getting the html to display the way I want it... The problem is the space between my table rows...I don't want space between my rows. I just want my table to look like a spreadsheet with black borders. I am using a datalist and have a table in the datalist control's templates. I have been messing with this for a couple of hours now and I have tried a few different variations of CSS and table attributes. Can anyone tell me where I am going wrong? Below is my current mark up. <style type="text/css"> .tdHeader { border-color: Black; border-style: solid; border-width: 1px; font-family: Arial; font-size: 8pt; margin: 0; background-color: #DCDCDC; font-weight: bold; } .tdBorder { border-color: Black; border-style: solid; border-width: 1px; font-family: Arial; font-size: 8pt; margin: 0; text-align: center; } .trNoSpace { margin: 0; padding: 0; } </style> <asp:DataList ID="DataList1" runat="server" DataKeyField="Oid" DataSourceID="xdsHUDEligibilityMember"> <HeaderTemplate> <table cellspacing="0" width="600"> <tr class="trNoSpace"> <td class="tdHeader" width="100">Household Member Number </td> <td class="tdHeader">Household Member Name </td> <td class="tdHeader">Age of Household Member </td> </tr> </HeaderTemplate> <ItemTemplate> <tr class="trNoSpace"> <td class="tdBorder"> <asp:Label ID="Label2" runat="server" Text='<%# Eval("Oid") %>' /> </td> <td class="tdBorder"> <asp:Label ID="Label1" runat="server" Text='<%# Eval("FullName") %>' /> </td> <td class="tdBorder"> <asp:Label ID="AgeAtEffectiveDateLabel" runat="server" Text='<%# Eval("AgeAtEffectiveDate") %>' /> </td> </tr> </ItemTemplate> <FooterTemplate> <tr class="trNoSpace"> <td class="tdBorder"> </td> <td class="tdBorder"> </td> <td class="tdBorder"> </td> </tr> </table> </FooterTemplate>

  • Do classes which have a vector has a member have memory issues

    - by user263766
    I am just starting out C++, so sorry if this is a dumb question. I have a class Braid whose members are vectors. I have not written an assignment operator. When I do a lot of assignments to an object of the type Braid, I run into memory issues :- 0 0xb7daff89 in _int_malloc () from /lib/libc.so.6 #1 0xb7db2583 in malloc () from /lib/libc.so.6 #2 0xb7f8ac59 in operator new(unsigned int) () from /usr/lib/libstdc++.so.6 #3 0x0804d05e in __gnu_cxx::new_allocator<int>::allocate (this=0xbf800204, __n=1) at /usr/lib/gcc/i686-pc-linux-gnu/4.4.3/../../../../include/c++/4.4.3/ext/new_allocator.h:89 #4 0x0804cb0e in std::_Vector_base<int, std::allocator<int> >::_M_allocate (this=0xbf800204, __n=1) at /usr/lib/gcc/i686-pc-linux-gnu/4.4.3/../../../../include/c++/4.4.3/bits/stl_vector.h:140 #5 0x0804c086 in _Vector_base (this=0xbf800204, __n=1, __a=...) at /usr/lib/gcc/i686-pc-linux-gnu/4.4.3/../../../../include/c++/4.4.3/bits/stl_vector.h:113 #6 0x0804b4b7 in vector (this=0xbf800204, __x=...) at /usr/lib/gcc/i686-pc-linux-gnu/4.4.3/../../../../include/c++/4.4.3/bits/stl_vector.h:242 #7 0x0804b234 in Braid (this=0xbf800204) at braid.h:13 #8 0x080495ed in Braid::cycleBraid (this=0xbf8001b4) at braid.cpp:191 #9 0x080497c6 in Braid::score (this=0xbf800298, b=...) at braid.cpp:251 #10 0x08049c46 in Braid::evaluateMove (this=0xbf800468, move=1, pos=0, depth=2, b=...) I suspect that these memory issues are because the vectors are getting resized. What I want to know is whether objects of type Braid automatically expand when its members expand? he code I am writing is really long so I will post the section which is causing the problems. Here is the relevant section of the code :- class Braid { private : vector<int> braid; //Stores the braid. int strands; vector < vector<bool> > history; vector < vector<bool> > CM; public : Braid () : strands(0) {} Braid operator * (Braid); Braid* inputBraid(int,vector<int>); int printBraid(); int printBraid(vector<vector<int>::iterator>); vector<int>::size_type size() const; ..... ..... } Here is the function which causes the issue :- int Braid::evaluateMove(int move,int pos,int depth,Braid b) { int netscore = 0; Braid curr(*this); curr = curr.move(move,pos); netscore += curr.score(b); while(depth > 1) { netscore += curr.evaluateMove(1,0,depth,b); netscore += curr.evaluateMove(2,0,depth,b); for(int i = 0; i < braid.size();++i) { netscore += curr.evaluateMove(3,i,depth,b); netscore += curr.evaluateMove(4,i,depth,b); netscore += curr.evaluateMove(5,i,depth,b); curr = curr.cycleBraid(); netscore += curr.evaluateMove(6,0,depth,b); } --depth; } return netscore; }

  • nil object in view when building objects on two different associations

    - by Shako
    Hello all. I'm relatively new to Ruby on Rails so please don't mind my newbie level! I have following models: class Paintingdescription < ActiveRecord::Base belongs_to :paintings belongs_to :languages end class Paintingtitle < ActiveRecord::Base belongs_to :paintings belongs_to :languages end class Painting < ActiveRecord::Base has_many :paintingtitles, :dependent => :destroy has_many :paintingdescriptions, :dependent => :destroy has_many :languages, :through => :paintingdescriptions has_many :languages, :through => :paintingtitles end class Language < ActiveRecord::Base has_many :paintingtitles, :dependent => :nullify has_many :paintingdescriptions, :dependent => :nullify has_many :paintings, :through => :paintingtitles has_many :paintings, :through => :paintingdescriptions end In my painting new/edit view, I would like to show the painting details, together with its title and description in each of the languages, so I can store the translation of those field. In order to build the languagetitle and languagedescription records for my painting and each of the languages, I wrote following code in the new method of my Paintings_controller.rb: @temp_languages = @languages @languages.size.times{@painting.paintingtitles.build} @painting.paintingtitles.each do |paintingtitle| paintingtitle.language_id = @temp_languages[0].id @temp_languages.slice!(0) end @temp_languages = @languages @languages.size.times{@painting.paintingdescriptions.build} @painting.paintingdescriptions.each do |paintingdescription| paintingdescription.language_id = @temp_languages[0].id @temp_languages.slice!(0) end In form partial which I call in the new/edit view, I have <% form_for @painting, :html => { :multipart => true} do |f| %> ... <% languages.each do |language| %> <p> <%= label language, language.name %> <% paintingtitle = @painting.paintingtitles[counter] %> <% new_or_existing = paintingtitle.new_record? ? 'new' : 'new' %> <% prefix = "painting[#{new_or_existing}_title_attributes][]" %> <% fields_for prefix, paintingtitle do |paintingtitle_form| %> <%= paintingtitle_form.hidden_field :language_id%> <%= f.label :title %><br /> <%= paintingtitle_form.text_field :title%> <% end %> <% paintingdescription = @painting.paintingdescriptions[counter] %> <% new_or_existing = paintingdescription.new_record? ? 'new' : 'new' %> <% prefix = "painting[#{new_or_existing}_title_attributes][]" %> <% fields_for prefix, paintingdescription do |paintingdescription_form| %> <%= paintingdescription_form.hidden_field :language_id%> <%= f.label :description %><br /> <%= paintingdescription_form.text_field :description %> <% end %> </p> <% counter += 1 %> <% end %> ... <% end %> But, when running the code, ruby encounters a nil object when evaluating paintingdescription.new_record?: You have a nil object when you didn't expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.new_record? However, if I change the order in which I a) build the paintingtitles and painting descriptions in the paintings_controller new method and b) show the paintingtitles and painting descriptions in the form partial then I get the nil on the paintingtitles.new_record? call. I always get the nil for the objects I build in second place. The ones I build first aren't nil in my view. Is it possible that I cannot build objects for 2 different associations at the same time? Or am I missing something else? Thanks in advance!

  • C++ Problem resolution - is it the best way to simulate a "tuple"?

    - by fbin
    Hi everyone! I've got the following problem: "Write a template function vectorMAXMIN() that will accept a vector and a number indicating the size of the vector and will return the max and the min values of the vector"... So i think in it... Create a class vector to avoid the "size" passing value and control the insertions and can get from this the max and min values... ( dunno if it's a good idea ) The problem is "how to return a tuple?" When i read the problem, i thought in a tuple to return "max, min values" is it correct? The code: #include <iostream> template < typename T > class _tuple { public: T _Max; T _Min; }; template < typename T > class _vector { public: _vector( int cnt = 0); ~_vector(); _tuple< T > get_tuple( void ); void insert( const T ); private: T *ptr; int cnt; int MAX; }; template < typename T > _vector< T >::_vector( int N ) { ptr = new T [N] ; MAX = N; cnt = 0; } template < typename T > _tuple<T> _vector< T >::get_tuple( void ) { _tuple< T > _mytuple; _mytuple._Max = ptr[0]; _mytuple._Min = ptr[0]; for( int i = 1; i < cnt; i++) { if( _mytuple._Max > ptr[i] ) _mytuple._Max = ptr[i]; if( _mytuple._Min < ptr[i] ) _mytuple._Min = ptr[i]; } return _mytuple; } template < typename T > void _vector< T >::insert( const T element) { if( cnt == MAX ) std::cerr << "Error: Out of range!" << std::endl; else { ptr[cnt] = element; cnt++; } } template < typename T > _vector< T >::~_vector() { delete [] ptr; } int main() { _vector< int > v; _tuple < int > t; v.insert(2); v.insert(1); v.insert(5); v.insert(0); v.insert(4); t = v.get_tuple(); std::cout << "MAX:" << t._Max; std::cout << " MIN:" << t._Min; return 0; }
