  • Struts2 form elements UI too rigid

    - by jscoot
    Hello, i found a similar problem like this: http://stackoverflow.com/questions/2314296/struts2-form-elements but no answer is given until now. So here i post my difficulties with a vengeance. I am using Struts2 with version 2.1.6. When I leave the input elements such as <s:textfield>, <s:textarea>, etc. of a <s:form> with the default theme, the elements are rendered as: <tr> <td class="tdLabel"><label for="firstname" class="label">Firstname:</label></td> <td><input type="text" name="firstname" id="firstname"/></td> </tr> <tr> <td class="tdLabel"><label for="lastname" class="label">Lastname:</label></td> <td><input type="text" name="lastname" id="lastname"/></td> </tr> Now if i want to add something, say an html label, between the two elements, the result gets messed up as described in the related question above. Another problem is: for the <s:checkbox> item, it is just not possible to add an extra title. For example, this tag <s:checkbox id="defaultprinter" name="defaultprinter" key="lbl.defaultprinter"/> is rendered as: <tr> <td valign="top" align="right"></td> <td valign="top" align="left"> <input type="checkbox" name="defaultprinter" value="true" checked="checked" id="defaultprinter"/> <label for="defaultprinter" class="checkboxLabel">Default Printer</label> </td> </tr> By only setting the attributes of <s:checkbox>, i can't add any text to the first <td> shown above (here it is empty!). I don't know if the above rigid UI problems can be solved or there is any workarounds somewhere. Thanks in advance.

  • What's special about mouse capture and middle mouse button in WPF?

    - by Scott Bilas
    When I call CaptureMouse() in response to a MouseDown from the middle mouse button, it will capture and then release the mouse. Huh? I've tried using Preview events, setting Handled=true, doesn't make a difference. Am I not understanding mouse capture in WPF? Here's some minimal sample code that reproduces the problem. // TestListBox.cs using System.Diagnostics; using System.Windows.Controls; namespace Local { public class TestListBox : ListBox { public TestListBox() { MouseDown += (_, e) => { Debug.WriteLine("+MouseDown"); Debug.WriteLine(" Capture: " + CaptureMouse()); Debug.WriteLine("-MouseDown"); }; MouseUp += (_, e) => { Debug.WriteLine("+MouseUp"); ReleaseMouseCapture(); Debug.WriteLine("-MouseUp"); }; GotMouseCapture += (_, e) => Debug.WriteLine("GotMouseCapture"); LostMouseCapture += (_, e) => Debug.WriteLine("LostMouseCapture"); } } } Generating a default WPF app that has this for its main window will use the test class: <Window x:Class="Local.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:Local" Title="MainWindow" Height="350" Width="525"> <local:TestListBox> <ListBoxItem>1</ListBoxItem> <ListBoxItem>2</ListBoxItem> <ListBoxItem>3</ListBoxItem> <ListBoxItem>4</ListBoxItem> </local:TestListBox> </Window> Upon clicking the middle button down, I get this output: +MouseDown GotMouseCapture LostMouseCapture Capture: True -MouseDown So I'm calling CaptureMouse, which in turn grabs and then releases capture, yet returns true that capture was successfully acquired. What's going on here? Is it possible that this is something with my Logitech mouse driver doing something goofy, trying to initiate 'ultrascroll' or something?

  • PHP MySQL Zend-ACL - Find all inherited items (Children / Parents)

    - by Scoobler
    I have one MySQL DB table like the following, the resources table: id | name | type 1 | guest | user 2 | member | user 3 | moderator | user 4 | owner | user 5 | admin | user 6 | index | controller Onto the next table, the rules table: id | user_id | rule | resource_id | extras 1 | 2 | 3 | 1 | null 2 | 3 | 3 | 2 | null 3 | 4 | 3 | 3 | null 4 | 5 | 3 | 4 | null 5 | 6 | 1 | 1 | index,login,register 6 | 6 | 2 | 2 | login,register 7 | 6 | 1 | 2 | logout OK, sorry for the length, but I am trying to give a full picture of what I am trying to do. So the way it works, a role (aka user) can be granted (rule: 1) access to a controller, a role can inherit (rule: 3) access from another role or a role and be denied (rule: 2) access to a controller. (A user is a resource and a controller is a resource) Access to actions are granted / denied using the extras column. This all works, its not a problem with setting up the ACL within zend. What I am now trying to do is show the relationships; to do that I need to find the lowest level a role is granted access to a controller stopping if it has explicitly been removed. I plan on listing the roles. When I click a role, I want it to show all the controllers that role has access to. Then clicking on a controller shows the actions the role is allowed to do. So in the example above, a guest is allowed to view the index action of the index controller along with the login action. A member inherits the same access, but is then denied access to the login action and register action. A moderator inherits the rules of a member. So if I were to select the role moderator. I want to see the controller index listed. If I click on the controller, it should show the allowed actions as being action: index. (which was originally granted to the guest, but hasn't since been dissallowed) Is there any examples to doing this. I am obviously working with the Zend MVC (PHP) and MySQL. Even just a persudo code example would be a helpful starting point - this is one of the last parts of the jigsaw I am putting together. P.S. Obviously I have the ACL object - is it going to be easier to interigate that or is it better to do it my self via PHP/MySQL? The aim will be, show what a role can access which will then allow me to add or edit a role, controller and action in a GUI style (that is somewhat the easy bit) - currently I am updating the DB manually as I have been building the site.

  • Rendering problem with UITableview

    - by Spider-Paddy
    I have a very strange problem with a UITableview within a navigation controller on the iPhone simulator. Of the cells displayed, only some are correctly rendered. They are all supposed to look the same but the majority are missing the accessory I've set, scrolling the view changes which cell has the accessory so I suspect it's some sort of cell caching happening, although the contents are correct for each cell. I also set an image as the background and that was also only displaying sporadically but I fixed that by changing cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yellow-bar_short.png"]]; (which also only rendered a random cell with the background) to cell.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"yellow-bar_short.png"]]; I now need to fix the problem with the accessory only showing on a random cell. I tried moving the code from cellForRowAtIndex to willDisplayCell but it made no difference. I put in a log command to confirm that it is running through each frame. Basically it's a table view (UITableViewCellStyleSubtitle) that gets its info from a server & is then updated by a delegate method calling reload. Code is: -(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"%@", [NSString stringWithFormat:@"Setting colours for cell %i", indexPath.row]); // Set cell background // cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yellow-bar_short.png"]]; cell.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"yellow-bar_short.png"]]; cell.textLabel.backgroundColor = [UIColor clearColor]; cell.detailTextLabel.backgroundColor = [UIColor clearColor]; // detailTableViewAccessory is a view containing an imageview in this view's nib // i.e. nib <- view <- imageview <- image cell.accessoryView = detailTableViewAccessory; } // Called by data fetching object when done -(void)listDataTransferComplete:(ArticleListParser *)articleListParserObject { NSLog(@"Data parsed, reloading detail table"); self.currentTotalResultPages = (((articleListParserObject.currentArticleCount - 1) / 10) + 1); self.detailTableDataSource = [articleListParserObject.returnedArray copy]; // make a local copy of the returned array // Render table again with returned array data (neither of these 2 fixed it) [self.detailTableView performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:NO]; // [self.detailTableView reloadData]; // Re-enable necessary buttons (including table cells) letUserSelectRow = TRUE; [btnByName setEnabled:TRUE]; [btnByPrice setEnabled:TRUE]; // Remove please wait message NSLog(@"Removing please wait view"); [pleaseWaitViewControllerObject.view removeFromSuperview]; } I only included code that I thought was relevant, can supply more if needed. I can't test it on an iPhone yet so I don't know if it's maybe just a simulator anomaly or a bug in my code. I've always gotten good feedback from questions, any ideas?

  • Mac Safari randomly recreating cookie when I refresh my login screen. Very bizarre

    - by mcintyre321
    We have found an issue in our app where Safari on the Mac randomly recreates a login cookie from a logged off session. I have a fiddler archive with this behaviour here. Note that some stuff has been removed from this to make it easier to get, but nothing which sets a cookie or anything has been taken out - only repetitions of requests 3-8. I'll talk you through the running order Request 1: user logs out via call to /logout.aspx - Set-Cookie returned setting cookie expiry date to 1999 Requests 2-8: user refreshes login page sending calls to root or /res/en-US/s.js - no cookie is sent to server or received back, and access is denied. I have cut out a lot of requests of this nature from the log as they are boring Request 9: request for /res/en-US/s.js - Hv3 authentication cookie has mysteriously reappeared! Wat. There was NO set-cookie! WTFF! Request 10+ : now the cookie has reappeared, the site logs the user in AGAIN The cookie, when examined in Safari looks like <dict> <key>Created</key> <real>259603523.26834899</real> <key>Domain</key> <string>.mysite.dev</string> <key>Expires</key> <date>2010-03-24T16:05:22Z</date> <key>HttpOnly</key> <string>TRUE</string> <key>Name</key> <string>.Hv3</string> <key>Path</key> <string>/</string> </dict> One thing to note is that in Safari, the cookie domain is .mysite.dev not mysite.dev (which is the cookie domain specified in web.config) - however, given that access is denied in requests 2-8, it looks like the cookie has expired OK. If you look in the list of cookies in the browser during 2-8, the .Hv3 cookie is not there. Is this our bug or Safari's? What can I do to stop it happening?

  • Making a row of divs all be the same height using CSS

    - by pavel
    I have a row of divs that must all be the same height, but I have no way of knowing what that height might be ahead of time (the content comes from an external source). I initially tried placing the divs in an enclosing div and floated them left. I then set their height to be "100%", but this had no perceptible effect. By setting the height on the enclosing div to a fixed-height I could then get the floated divs to expand, but only up to the fixed height of the container. When the content in one of the divs exceeded the fixed height, it spilled over; the floated divs refused to expand. I Googled this floated-divs-of-the-same-height problem and apparently there's no way to do it using CSS. So now I am trying to use a combination of relative and absolute positioning instead of floats. This is the CSS: <style type="text/css"> div.container { background: #ccc; position: relative; min-height: 10em; } div.a { background-color: #aaa; position: absolute; top: 0px; left: 0px; bottom: 0px; width: 40%; } div.b { background-color: #bbb; position: absolute; top: 0px; left: 41%; bottom: 0px; width: 40%; } </style> This is a simplified version of the HTML: <div class="container"> <div class="a">Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Integer pretium dui sit amet felis. Integer sit amet diam. Phasellus ultrices viverra velit.</div> <div class="b">Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Integer pretium dui sit amet felis. Integer sit amet diam. Phasellus ultrices viverra velit. Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Integer pretium dui sit amet felis. Integer sit amet diam. Phasellus ultrices viverra velit.</div> </div> This works, unless you change the min-height to something like 5em (demonstranting what happens when the content exceeds the minimum height), and you can see that while the text doesn't get cutoff, the divs still refuse to expand. Now I am at a lose. Is there any way to do this using CSS?

  • asp.net Wizard control strange issue

    - by epitka
    Update: There was actually a hidden panel with validator in the user control that was causing page not to be valid on the first postback. Consider this issue resolved. This is first time I am using this control and it is behaving rather strange. I have to click on the "Next" button twice for it to move to the next step. I tried explicitly setting active index, using MoveTo etc. Nothing works. Here is the markup for the control. Anybody has any ideas why? <asp:Wizard ID="UserWizard" runat="server" ActiveStepIndex="0" StartNextButtonImageUrl = "~/App_Themes/Default/images/buttons/continue.gif" StartNextButtonType="Image" StepNextButtonType="Image" StepNextButtonImageUrl="~/App_Themes/Default/images/buttons/continue.gif" FinishPreviousButtonImageUrl="~/App_Themes/Default/images/buttons/back.gif" FinishPreviousButtonType="Image" FinishCompleteButtonImageUrl="~/App_Themes/Default/images/buttons/save.gif" FinishCompleteButtonType="Image" CancelButtonType="Image" CancelButtonImageUrl="~/App_Themes/Default/images/buttons/back.gif" DisplaySideBar="false" > <WizardSteps> <asp:WizardStep Title="User Profile" ID="UserProfile" runat="server"> <uhc:ctlUserProfileEdit ID="ctlUserProfileEdit" runat="server"> </uhc:ctlUserProfileEdit> <br clear="all" /> <div> <asp:ImageButton ID="cmdResetPassword" runat="server" ImageUrl="~/App_Themes/Default/images/buttons/resetpassword.gif" /> </div> <div> <asp:UpdatePanel ID="upSchools" runat="server" ChildrenAsTriggers="true"> <ContentTemplate> <uhc:ctlSchoolLocationSelector ID="ctlSchoolLocationSelector" runat="server" /> </ContentTemplate> </asp:UpdatePanel> </div> </asp:WizardStep> <asp:WizardStep Title="Roles" ID="Roles" runat="server"> <uhc:ctlPermissionInternal ID="ctlPermissionInternal1" runat="server"></uhc:ctlPermissionInternal> <uhc:ctlPermissionExternal ID="ctlPermissionExternal1" runat="server"></uhc:ctlPermissionExternal> </asp:WizardStep> </WizardSteps> </asp:Wizard>

  • How do I send a javascript variable to a subsequent jquery function or set of braces?

    - by desbest
    How do I send a javascript variable to a subsequent jquery function? Here is my code. <script type="text/javascript"> $(function() { var name = $("#name"), email = $("#email"), password = $("#password"), itemid = $("#itemid"), tips = $(".validateTips"); function updateTips(t) { tips .text(t) .addClass('ui-state-highlight'); setTimeout(function() { tips.removeClass('ui-state-highlight', 1500); }, 500); } $("#dialog-form").dialog({ autoOpen: false, height: 320, width: 350, modal: true, /* buttons: { 'Change category': function() { alert("The itemid2 is "+itemid2); var bValid = true; $('#users tbody').append('<tr>' + '<td>' + name.val() + '</td>' + '<td>' + email.val() + '</td>' + '<td>' + password.val() + '</td>' + '<td>' + itemid.val() + '</td>' + '</tr>'); $(this).dialog('close'); }, Cancel: function() { $(this).dialog('close'); } }, */ close: function() { allFields.val('').removeClass('ui-state-error'); } }); $('.changecategory') .button() .click(function() { var categoryid = $(this).attr("categoryid"); var itemid = $(this).attr("itemid"); var itemid2 = $(this).attr("itemid"); var itemtitle = $(this).attr("itemtitle"); var parenttag = $(this).parent().get(0).tagName; var removediv = "itemid_" +itemid; alert("The itemid is "+itemid); $('#dialog-form').dialog('open'); }); }); </script> I'll break it down. The .changecategory section happens FIRST when an image on my page is clicked. $("#dialog-form").dialog({ is then called, and the variable item id is not passed to this function. How can I pass a variable from one function to another? Is that possible. Is there a way I can pass a variable to another jquery function without having to resort of setting a cookie with javascript and then using jquery to read it?

  • Multiple choice test GUI with serialization of Q&A

    I'm working on a project for school in Java programming. I need to design a GUI that will take in questions and answers and store them in a file. It should be able to contain an unlimited number of questions. We have covered binary I/O. How do I write the input they give to a file? How would I go about having them add multiple questions from this GUI? package multiplechoice; import java.awt.*; import javax.swing.*; public class MultipleChoice extends JFrame { public MultipleChoice() { /* * Setting Layout */ setLayout(new GridLayout(10,10)); /* * First Question */ add(new JLabel("What is the category of the question?: ")); JTextField category = new JTextField(); add(category); add(new JLabel("Please enter the question you wish to ask: ")); JTextField question = new JTextField(); add(question); add(new JLabel("Please enter the correct answer: ")); JTextField correctAnswer = new JTextField(); add(correctAnswer); add(new JLabel("Please enter a reccomended answer to display: ")); JTextField reccomendedAnswer = new JTextField(); add(reccomendedAnswer); add(new JLabel("Please enter a choice for multiple choice option " + "A")); JTextField A = new JTextField(); add(A); add(new JLabel("Please enter a choice for multiple choice option " + "B")); JTextField B = new JTextField(); add(B); add(new JLabel("Please enter a choice for multiple choice option " + "C")); JTextField C = new JTextField(); add(C); add(new JLabel("Please enter a choice for multiple choice option " + "D")); JTextField D = new JTextField(); add(D); add(new JButton("Compile Questions")); add(new JButton("Next Question")); } public static void main(String[] args) { /* * Creating JFrame to contain questions */ FinalProject frame = new FinalProject(); // FileOutputStream output = new FileOutputStream("Questions.dat"); JPanel panel = new JPanel(); // button.setLayout(); // frame.add(panel); panel.setSize(100,100); // button.setPreferredSize(new Dimension(100,100)); frame.setTitle("FinalProject"); frame.setSize(600, 400); frame.setLocationRelativeTo(null); // Center the frame frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); } }

  • How to use jaxb_commons plugins from maven

    I'm trying to use a jaxb plugin to insert a interface into a choice element generating the classes from maven. The problem is that I can't seem to figure out how to do so from maven, the repository isn't clear from the documentation and the only example (bellow) doesn't work, it seems to ignore the plugin (maven reports no error about not finding it) or the plugin doesn't have all the adds-ons currently listed in the project documentation: <plugin> <groupId>org.jvnet.jaxb2.maven2</groupId> <artifactId>maven-jaxb2-plugin</artifactId> <version>0.6.1</version> <executions> <execution> <goals> <goal>generate</goal> </goals> </execution> </executions> <configuration> <generatePackage>br.com.wonder.nfe.xml</generatePackage> <args> <arg>-Xifins</arg> </args> <plugins> <plugin> <groupId>org.jvnet.jaxb2_commons</groupId> <artifactId>basic</artifactId> <version>0.4.1.5</version> </plugin> </plugins> </configuration> </plugin> I have these in the root pom: <pluginRepositories> <pluginRepository> <id>maven2-repository.dev.java.net</id> <url>http://download.java.net/maven/2</url> </pluginRepository> <pluginRepository> <id>maven-repository.dev.java.net</id> <name>Java.net Maven 1 Repository (legacy)</name> <url>http://download.java.net/maven/1</url> <layout>legacy</layout> </pluginRepository> </pluginRepositories> Running that gives: Error while setting CmdLine options '[-Xifins, -episode, /home/administrador/JavaApp/wnfe3/wnfe-ejb/target/generated-sources/xjc/META-INF/sun-jaxb.episode]'!

  • Illegal Instruction When Programming C++ on Linux

    - by remagen
    Heyo, My program, which does exactly the same thing every time it runs (moves a point sprite into the distance) will randomly fail with the text on the terminal 'Illegal Instruction'. My googling has found people encountering this when writing assembly which makes sense because assembly throws those kinds of errors. But why would g++ be generating an illegal instruction like this? It's not like I'm compiling for Windows then running on Linux (which even then, as long as both are on x86 shouldn't AFAIK cause an Illegal Instruction). I'll post the main file below. I can't reliably reproduce the error. Although, if I make random changes (add a space here, change a constant there) that force a recompile I can get a binary which will fail with Illegal Instruction every time it is run, until I try setting a break point, which makes the illegal instruction 'dissapear'. :( #include <stdio.h> #include <stdlib.h> #include <GL/gl.h> #include <GL/glu.h> #include <SDL/SDL.h> #include "Screen.h" //Simple SDL wrapper #include "Textures.h" //Simple OpenGL texture wrapper #include "PointSprites.h" //Simple point sprites wrapper double counter = 0; /* Here goes our drawing code */ int drawGLScene() { /* These are to calculate our fps */ static GLint T0 = 0; static GLint Frames = 0; /* Move Left 1.5 Units And Into The Screen 6.0 */ glLoadIdentity(); glTranslatef(0.0f, 0.0f, -6); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT); glEnable(GL_POINT_SPRITE_ARB); glTexEnvi(GL_POINT_SPRITE, GL_COORD_REPLACE, GL_TRUE); glBegin( GL_POINTS ); /* Drawing Using Triangles */ glVertex3d(0.0,0.0, 0); glVertex3d(1.0,0.0, 0); glVertex3d(1.0,1.0, counter); glVertex3d(0.0,1.0, 0); glEnd( ); /* Finished Drawing The Triangle */ /* Move Right 3 Units */ /* Draw it to the screen */ SDL_GL_SwapBuffers( ); /* Gather our frames per second */ Frames++; { GLint t = SDL_GetTicks(); if (t - T0 >= 50) { GLfloat seconds = (t - T0) / 1000.0; GLfloat fps = Frames / seconds; printf("%d frames in %g seconds = %g FPS\n", Frames, seconds, fps); T0 = t; Frames = 0; counter -= .1; } } return 1; } GLuint objectID; int main( int argc, char **argv ) { Screen screen; screen.init(); screen.resize(800,600); LoadBMP("./dist/Debug/GNU-Linux-x86/particle.bmp"); InitPointSprites(); while(true){drawGLScene();} }

  • C++ class member functions instantiated by traits

    - by Jive Dadson
    I am reluctant to say I can't figure this out, but I can't figure this out. I've googled and searched Stack Overflow, and come up empty. The abstract, and possibly overly vague form of the question is, how can I use the traits-pattern to instantiate non-virtual member functions? The question came up while modernizing a set of multivariate function optimizers that I wrote more than 10 years ago. The optimizers all operate by selecting a straight-line path through the parameter space away from the current best point (the "update"), then finding a better point on that line (the "line search"), then testing for the "done" condition, and if not done, iterating. There are different methods for doing the update, the line-search, and conceivably for the done test, and other things. Mix and match. Different update formulae require different state-variable data. For example, the LMQN update requires a vector, and the BFGS update requires a matrix. If evaluating gradients is cheap, the line-search should do so. If not, it should use function evaluations only. Some methods require more accurate line-searches than others. Those are just some examples. The original version instantiates several of the combinations by means of virtual functions. Some traits are selected by setting mode bits that are tested at runtime. Yuck. It would be trivial to define the traits with #define's and the member functions with #ifdef's and macros. But that's so twenty years ago. It bugs me that I cannot figure out a whiz-bang modern way. If there were only one trait that varied, I could use the curiously recurring template pattern. But I see no way to extend that to arbitrary combinations of traits. I tried doing it using boost::enable_if, etc.. The specialized state information was easy. I managed to get the functions done, but only by resorting to non-friend external functions that have the this-pointer as a parameter. I never even figured out how to make the functions friends, much less member functions. The compiler (VC++ 2008) always complained that things didn't match. I would yell, "SFINAE, you moron!" but the moron is probably me. Perhaps tag-dispatch is the key. I haven't gotten very deeply into that. Surely it's possible, right? If so, what is best practice?

  • assignment not working in a dll exported C++ class

    - by Jim Jones
    Using VS 2008 Have a C++ class in which I'm calling functions from a 3rd party dll. The definition in the header file is as follows: namespace OITImageExport { class ImageExport { private: SCCERR seResult; /* Error code returned. */ VTHDOC hDoc; /* Input doc handle returned by DAOpenDocument(). */ VTHEXPORT hExport; /* Handle to the export returned by EXOpenExport(). */ VTDWORD dwFIFlags; /* Used in setting the SCCOPT_FIFLAGS option. */ VTCHAR szError[256]; /* Error string buffer. */ VTDWORD dwOutputId; /* Output Format. */ VTDWORD dwSpecType; public: ImageExport(const char* outputId, const char* specType); void ProcessDocument(const char* inputPath, const char* outputPath); ~ImageExport(); }; } In the constructor I initialize two of the class fields having values which come from enumerations in the 3rd party dll: ImageExport::ImageExport(const char* outputId, const char* specType) { if(outputId == "jpeg") { dwOutputId = FI_JPEGFIF; } if(specType == "ansi") { dwSpecType = IOTYPE_ANSIPATH; } seResult = DAInit(); if (seResult != SCCERR_OK) { DAGetErrorString(seResult, szError, sizeof(szError)); fprintf(stderr, "DAInit() failed: %s (0x%04X)\n", szError, seResult); exit(seResult); } } When I use this class inside of a console app, with a main method in another file (all in the same namespace), instantiating the class object and calling the methods, it works like a champ. So, now that I know the basic code works, I open a dll project using the class header and code file. Course I have to add the dll macro, namely: #ifdef IMAGEDLL_EXPORTS #define DLL __declspec(dllexport) #else #define DLL __declspec(dllimport) #endif and changed the class definition to "class DLL ImageExport". Compiled nicely to a dll and .lib file (No errors, No warnings). Now to test this dll I open another console project using the same main method as before and linking to the (dll) lib file. Had problems, which when tracked down were the result of the two fields not being set; both had values of 0. Went back to the first console app and printed out the values: dwOutputId was 1535 (#define FI_JPEGFIF 1535) and dwSpecType was 2 (#define IOTYPE_ANSIPATH 2). Now if I was assigning these values outside of the class, I can see how the visibility could be different, but why is the assignment in the dll not working? Is it something about having a class in the dll?

  • non blocking TCP-acceptor not reading from socket

    - by Abruzzo Forte e Gentile
    I have the code below implementing a NON-Blocking TCP acceptor. Clients are able to connect without any problem and the writing seems occurring as well, but the acceptor doesn't read anything from the socket and the call to read() blocks indefinitely. Am I using some wrong setting for the acceptor? Kind Regards AFG int main(){ create_programming_socket(); poll_programming_connect(); while(1){ poll_programming_read(); } } int create_programming_socket(){ int cnt = 0; p_listen_socket = socket( AF_INET, SOCK_STREAM, 0 ); if( p_listen_socket < 0 ){ return 1; } int flags = fcntl( p_listen_socket, F_GETFL, 0 ); if( fcntl( p_listen_socket, F_SETFL, flags | O_NONBLOCK ) == -1 ){ return 1; } bzero( (char*)&p_serv_addr, sizeof(p_serv_addr) ); p_serv_addr.sin_family = AF_INET; p_serv_addr.sin_addr.s_addr = INADDR_ANY; p_serv_addr.sin_port = htons( p_port ); if( bind( p_listen_socket, (struct sockaddr*)&p_serv_addr , sizeof(p_serv_addr) ) < 0 ) { return 1; } listen( p_listen_socket, 5 ); return 0; } int poll_programming_connect(){ int retval = 0; static socklen_t p_clilen = sizeof(p_cli_addr); int res = accept( p_listen_socket, (struct sockaddr*)&p_cli_addr, &p_clilen ); if( res > 0 ){ p_conn_socket = res; int flags = fcntl( p_conn_socket, F_GETFL, 0 ); if( fcntl( p_conn_socket, F_SETFL, flags | O_NONBLOCK ) == -1 ){ retval = 1; }else{ p_connected = true; } }else if( res == -1 && ( errno == EWOULDBLOCK || errno == EAGAIN ) ) { //printf( "poll_sock(): accept(c_listen_socket) would block\n"); }else{ retval = 1; } return retval; } int poll_programming_read(){ int retval = 0; bzero( p_buffer, 256 ); int numbytes = read( p_conn_socket, p_buffer, 255 ); if( numbytes > 0 ) { fprintf( stderr, "poll_sock(): read() read %d bytes\n", numbytes ); pkt_struct2_t tx_buf; int fred; int i; } else if( numbytes == -1 && ( errno == EWOULDBLOCK || errno == EAGAIN ) ) { //printf( "poll_sock(): read() would block\n"); } else { close( p_conn_socket ); p_connected = false; retval = 1; } return retval; }

  • Why is this line breaking Rails with Passenger on DreamHost?

  • vb.net how to start a folder monitor service at runtime and pass on the folder path to monitor?

    - by mazrabul
    hi, I have the following windows service file: Imports System.ServiceProcess Imports System.IO Public Class fswService Dim fsw As FileSystemWatcher Dim lf As StreamWriter Protected Overrides Sub OnStart(ByVal args As String()) ' Add code here to start your service. This method should set things ' in motion so your service can do its work. lf = New StreamWriter(Application.StartupPath & "\fsw_lg.log") fsw = New FileSystemWatcher() fsw.Path = args(0) fsw.IncludeSubdirectories = True fsw.Filter = ".txt" fsw.EnableRaisingEvents = True AddHandler fsw.Created, New FileSystemEventHandler(AddressOf file_created) AddHandler fsw.Changed, New FileSystemEventHandler(AddressOf file_changed) AddHandler fsw.Deleted, New FileSystemEventHandler(AddressOf file_deleted) End Sub Public Sub file_created(ByVal obj As Object, ByVal e As FileSystemEventArgs) lf.WriteLine(Now.ToShortDateString & "-" & Now.ToShortTimeString & "-" & e.FullPath & "-created") End Sub Public Sub file_changed(ByVal obj As Object, ByVal e As FileSystemEventArgs) lf.WriteLine(Now.ToShortDateString & "-" & Now.ToShortTimeString & "-" & e.FullPath & "-changed") End Sub Public Sub file_deleted(ByVal obj As Object, ByVal e As FileSystemEventArgs) lf.WriteLine(Now.ToShortDateString & "-" & Now.ToShortTimeString & "-" & e.FullPath & "-deleted") End Sub Protected Overrides Sub OnStop() lf.Close() End Sub End Class i have the ServiceName set to fswService (same as class name). When I added an installer I also set the ServiceName for the ServiceInstaller1 as fswService. I want to start this service at runtime based on the user setting the path of the folder to be watched. To achieve this I have the following: Dim fsw_controller As New ServiceProcess.ServiceController fsw_controller.Start(fswService) 2 problems: first, intellisense error saying: 'fswService' is a type and cannot be used as an expression. second, I can not figure out a way to pass on to the service the path of the folder to watch (which is stored at My.Settings.userPath). I really thought this is how you start a service. Am I missing something? Your help is, as always, appreciated. Thanks

  • How can I run an android frame animation without it skewing?

    - by GameDev123
    I have a small state machine that runs a series of frame by frame animations in an ImageView, in a nested hierarchy of layouts. There is more than adequate space to display each frame of the animation. Each frame of the animation is cropped to fit the minimum amount of area, in order to save memory. If a frame only contains 50x50 worth of pixels then the png is 50x50. There is no transparent padding to keep them the same size. The ImageView is directly within a RelativeLayout, and is anchored to the bottom left with some padding. The general idea being that the character in the animation performs some action, which results in individual frames of the animation growing or shrinking. The issue is that individual frames of animation are skewed, and there does not appear to be any way of preventing this. If I set the source of the imageview directly to one of the frames of animation, it displays fine in the layout manager. I have tried this with Adjust View Bounds set to true, false, and undefined. I have tried using the background and the src attribute of imageview to set the animation drawable, I have tried every configuration of layout manager and setting minimum/maximum size that I can think of, and it still stretches the character on various frames depending on the size of the source png. In essence, all I want to do is say "I want this ImageView to anchor in the bottom left and then display any frame that happens to be in it without stretching or skewing it in any way aside from that which occurred when the frame png's were loaded." Seems simple, but I have yet to come across any way of doing it. Here is the layout of the imageview as of my last test, I had to remove bits of the XML to get it to display but nothing pertinent: RelativeLayout android:orientation="horizontal" android:layout_above="@+id/MenuOptions" android:layout_width="fill_parent" android:id="@+id/AnimationLayout" android:clipChildren="false" android:minHeight="180dp" android:layout_height="fill_parent" android:layout_below="@+id/GameBarLayout" ImageView android:id="@+id/animatedImg" android:layout_height="wrap_content" android:layout_width="wrap_content" android:visibility="visible" android:baselineAlignBottom="true" android:minHeight="180dp" android:minWidth="200dp" android:adjustViewBounds="true" android:layout_alignParentBottom="true" android:paddingLeft="30dp" android:paddingBottom="10dp" android:src="@drawable/idle01"/ImageView /RelativeLayout Here is how an animation is set up: animationDrawable = new AnimationDrawable(); animationDrawable.addFrame(res.getDrawable(R.drawable.idle01), 16); animationDrawable.addFrame(res.getDrawable(R.drawable.idle02), 16); animationDrawable.addFrame(res.getDrawable(R.drawable.idle03), 16);

  • C++ Vector vs Array (Time)

    - by vsha041
    I have got here two programs with me, both are doing exactly the same task. They are just setting an boolean array / vector to the value true. The program using vector takes 27 seconds to run whereas the program involving array with 5 times greater size takes less than 1 s. I would like to know the exact reason as to why there is such a major difference ? Are vectors really that inefficient ? Program using vectors #include <iostream> #include <vector> #include <ctime> using namespace std; int main(){ const int size = 2000; time_t start, end; time(&start); vector<bool> v(size); for(int i = 0; i < size; i++){ for(int j = 0; j < size; j++){ v[i] = true; } } time(&end); cout<<difftime(end, start)<<" seconds."<<endl; } Runtime - 27 seconds Program using Array #include <iostream> #include <ctime> using namespace std; int main(){ const int size = 10000; // 5 times more size time_t start, end; time(&start); bool v[size]; for(int i = 0; i < size; i++){ for(int j = 0; j < size; j++){ v[i] = true; } } time(&end); cout<<difftime(end, start)<<" seconds."<<endl; } Runtime - < 1 seconds Platform - Visual Studio 2008 OS - Windows Vista 32 bit SP 1 Processor Intel(R) Pentium(R) Dual CPU T2370 @ 1.73GHz Memory (RAM) 1.00 GB Thanks Amare

  • How can a button click method find out which item is selected in a ListView?

    - by Ian Bayley
    I have a single screen with a bank of buttons below a ListView. Entries on the ListView light up in orange when I scroll so I assume that are selected. When I then press the "Delete" button I want the onClickListener to remove the currently selected entry. But getSelectedItemPosition() always gives me -1. If I can't hope to use the GUI controls in this way, please give me another way of getting the same result. I have even tried setting the onClickListener of the List View to store the index before the button is pressed (in case pressing the button unselects the entry) but even that is always -1 it seems. Here's the code (without the modification which didn't work) package com.bayley; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter; import android.widget.Button; import android.widget.EditText; import android.widget.ListView; import java.util.ArrayList; /** * * @author p0074564 */ public class September extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); final ListView myListView = (ListView) findViewById(R.id.myListView); Button addButton = (Button) findViewById(R.id.AddButton); Button deleteButton = (Button) findViewById(R.id.DeleteButton); final EditText editText = (EditText) findViewById(R.id.myEditText); final ArrayList<String> todoItems = new ArrayList<String>(); todoItems.add("Monday"); todoItems.add("Tuesday"); todoItems.add("Wednesday"); final ArrayAdapter<String> aa = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, todoItems); myListView.setAdapter(aa); addButton.setOnClickListener(new Button.OnClickListener() { public void onClick(View v) { todoItems.add(editText.getText().toString()); aa.notifyDataSetChanged(); } }); deleteButton.setOnClickListener(new Button.OnClickListener() { public void onClick(View v) { // always returns -1 unfortunately ie nothing is ever selected int index = myListView.getSelectedItemPosition(); if (index >= 0) { todoItems.remove(index); } aa.notifyDataSetChanged(); } }); } }

  • Get content in iframe to use as much space as it needs

    - by Mark
    I'm trying to write a simple JavaScript based modal dialog. The JavaScript function takes the content, puts it in a new iframe and adds the iframe to the page. Works great so far, the only problem is that the content of the dialog (e.g. a table) gets wrapped, although plenty of space is available on the page. I'd like the content of the dialog, a table in my case, to use as much space as it needs, without wrapping any lines. I tried lots of combinations of setting width/style.width on the iframe and the table. Nothing did the trick. Here the code to show the iframe dialog: function SimpleDialog() { this.domElement = document.createElement('iframe'); this.domElement.setAttribute('style', 'border: 1px solid red; z-index: 201; position: absolute; top: 0px; left: 0px;'); this.showWithContent = function(content) { document.getElementsByTagName('body')[0].appendChild(this.domElement); this.domElement.contentDocument.body.appendChild(content); var contentBody = this.domElement.contentDocument.body; contentBody.style.padding = '0px'; contentBody.style.margin = '0px'; // Set the iframe size to the size of content. // However, content got wrapped already. this.domElement.style.height = content.offsetHeight + 'px'; this.domElement.style.width = content.offsetWidth + 'px'; this._centerOnScreen(); }; this._centerOnScreen = function() { this.domElement.style.left = window.pageXOffset + (window.innerWidth / 2) - (this.domElement.offsetWidth / 2) + 'px'; this.domElement.style.top = window.pageYOffset + (window.innerHeight / 2) - (this.domElement.offsetHeight / 2) + 'px'; }; } Here the test code: var table = document.createElement('table'); table.setAttribute('style', 'border: 1px solid black; width: 100%;'); table.innerHTML = "<tr><td style='font-size:40px;'>Hello world in big letters</td></tr><tr><td>second row</td></tr>"; var dialog = new SimpleDialog(); dialog.showWithContent(table); The table shows up nicely centered on the page, but the words in the first cell are wrapped to two lines. How do I get the table to use as much space as it needs (without using white-space: nowrap ;) Thanks in advance for any suggestions! -Mark

  • sifr menu list problems, height of object calculated wrong

    - by armyofda12mnkeys
    I am using Drupal and have sifr set on list items, and also a, a:hover are set via Drupal so that the links hover. I looked at the sifr3-rules.js file drupal's render module creates and it looks good. and in fact my other sifr items look fine... But the list item ones are goofing for some reason... There is extra space below the list, so if i have a list item, and inside of that, I have a unordered list with more list items, the Flash Object made in the 1st li (which will cover the rest of the sublist items too), is too bid so you see space under the children until the next parent li comes up. (so looks like extra bottom padding on that portion of the list in IE8... in FF almost similar but each subitem has space at bottom... with javascript turned off, you see the list items look fine by themselves).... Also if the parent list item is shorter than the sub list items text, the width for the flash object is set only as long as the first list item, and therefore cuts off the rest the sublist item's text. Any idea how to resolve any of these? Only unusual thing i see i am doing is setting forceSingleLine and preventWrap (which dont make a difference if taken off). ****Edit, I may just try to figure out how to get Drupal's menu-block module to output a around my hyperlinks in the list items... then i can target the div's with my rule (and the a,a:hover rules will apply), so each menu item gets its own sifr object instead of sifr3 trying to figure out how to do the lists and sublists. Very useful to me is anyone knows a way to target a hyperlink (<a> tag) and also allow a:hover rules. I know how to do it with pretend another tag that includes hyperlinks, like if i had <h2><a>sometitle</a></h2>, i could have a rule for h2, but then use the a, a:hover rules in the sifr3-rules.js file to target that. so i would need a way to target the hyperlink in the list, but also apply a :hover to it (not sure if this can be done since its not underneith for example the h2 tag).

  • Why this search can not generate correct result?

    - by user482742
    Hi, All: Below is to find same customer and if he is in list, the number add one. If he is not in the list, just add him in the list. I use Search function to do this, but failed and generated incorrect records. It can not find the customer or the right number of customers. But if I use For..loop to iterate the list, it does well and can find the customer and add new customer in that for..loop search procedure. (I did not paste for ..loop search procedrue here). Another problem is that there is no difference between setting list.sorted true and false. It seems Search function is not correct. This search function is from an example of delphi textbook. The below is with Delphi 7. Thank you. Procedure Form1.create; begin list:=Tstringlist.create; list.sorted:=true; // Search function will generate exactly Same and Incorrect //records no matter list.sorted is set true or false. list.duplicates:=dupignore; .. end; Procedure addcustomer; var .. begin while p1.MatchAgain do begin //p1 is regular expression customer:=p1.MatchedExpression; if (search(customer)=false) then begin list.Add(customer+'=1'); end; allcustomer:=allcustomer+1; .. end; Function Tform1.search(customer: string): boolean; var fre:string; num:integer; L:integer; R:integer; M: Integer; CompareResult: Integer; found: boolean; begin result:=false; found:=false; L := 0; R := List.Count - 1; while (L <= R) and ( not found ) do begin M := (L + R) div 2; CompareResult := Comparetext(list.Names[m]), customer); if (compareresult=0) then begin fre:=list.ValueFromIndex [m]; num:=strtoint(fre); num:=num+1; list.ValueFromIndex[m]:=inttostr(num); Found := True; Result := true; exit; end else if compareresult > 0 then r := m - 1 else l := m + 1; end; end;
