  • Is there a more elegant solution than an if-statement with no else clause?

    - by Jay
    In the following code, if Control (the element that trigers Toggle's first OL) is not Visible it should be set Visible and all other Controls (Controls[i]) so be Hidden. .js function Toggle(Control){ var Controls=document.getElementsByTagName("ol",document.getElementById("Quote_App")); var Control=Control.getElementsByTagName("ol")[0]; if(Control.style.visibility!="visible"){ for(var i=0;i<Controls.length;i++){ if(Controls[i]!=Control){ Reveal("hide",20,0.3,Controls[i]); }else{ Reveal("show",20,0.3,Control); }; }; }else{ Reveal("hide",20,0.3,Control); }; }; Although the function [Toggle] works fine, it is actually setting Controls[i] to Hidden even if it is already. This is easily rectified by adding an If statement as in the code below, surely there is a more elegant solution, maybe a complex If condition? .js function Toggle(Control){ var Controls=document.getElementsByTagName("ol",document.getElementById("Quote_App")); var Control=Control.getElementsByTagName("ol")[0]; if(Control.style.visibility!="visible"){ for(var i=0;i<Controls.length;i++){ if(Controls[i]!=Control){ if(Controls[i].style.visibility=="visible"){ Reveal("hide",20,0.3,Controls[i]); }; }else{ Reveal("show",20,0.3,Control); }; }; }else{ Reveal("hide",20,0.3,Control); }; }; Your help is appreciated always.

  • Garbage data from serial port.

    - by sasayins
    Hi I wrote a code in Linux platform that read the data in serial port, my code below: int fd; char *rbuff=NULL; struct termios new_opt, old_opt; int ret; fd = open("/dev/ttyS0", O_RDWR | O_NOCTTY); if( fd == -1 ) { printf("Can't open file: %s\n", strerror(errno)); return -1; } tcgetattr(fd, &old_opt); new_opt.c_cflag = B115200 | CS8 | CLOCAL | CREAD; new_opt.c_iflag = IGNPAR /*| ICRNL*/; new_opt.c_oflag = 0; new_opt.c_lflag = ICANON; tcsetattr(fd, TCSANOW, &new_opt); rbuff = malloc(NBUFF); printf("reading..\n"); memset(rbuff,0x00,NBUFF); ret = read(fd, rbuff, NBUFF); printf("value:%s",rbuff); if(ret == -1) { printf("Read error:%s\n",strerror(errno)); return -1; } tcsetattr(fd, TCSANOW, &old_opt); close(fd); My problem is the code above doesn't read the first data that was transmitted, then the second transmission the data is garbage, then the third is the normal data. Did I missed a setting in the serial port? Thanks.

  • class modifier issues in C# with "private" classes

    - by devoured elysium
    I had a class that had lots of methods: public class MyClass { public bool checkConditions() { return checkCondition1() && checkCondition2() && checkCondition3(); } ...conditions methods public void DoProcess() { FirstPartOfProcess(); SecondPartOfProcess(); ThirdPartOfProcess(); } ...process methods } I identified two "vital" work areas, and decided to extract those methods to classes of its own: public class MyClass { private readonly MyClassConditions _conditions = new ...; private readonly MyClassProcessExecution = new ...; public bool checkConditions() { return _conditions.checkConditions(); } public void DoProcess() { _process.DoProcess(); } } In Java, I'd define MyClassConditions and MyClassProcessExecution as package protected, but I can't do that in C#. How would you go about doing this in C#? Setting both classes as inner classes of MyClass? I have 2 options: I either define them inside MyClass, having everything in the same file, which looks confusing and ugly, or I can define MyClass as a partial class, having one file for MyClass, other for MyClassConditions and other for MyClassProcessExecution. Defining them as internal? I don't really like that much of the internal modifier, as I don't find these classes add any value at all for the rest of my program/assembly, and I'd like to hide them if possible. It's not like they're gonna be useful/reusable in any other part of the program. Keep them as public? I can't see why, but I've let this option here. Any other? Name it! Thanks

  • Indirect property notification

    - by Carlo
    Hello, this question might look a little trivial, but it might not be. I'm just wondering which of the following two cases is better for indirect property notification, or perhaps there is an even better way. The scenario: I have two properties, the first one is an object called HoldingObject, the second one is a boolean called IsHoldingObject, which is false if HoldingObject == null, otherwise it's true. I'm just wondering what is the best notification mechanism for IsHoldingObject: Case (A) - Notify IsHoldingObject changed from the HoldingObject proeperty: public class NotifyingClass1 : INotifyPropertyChanged { private object _holdingObject; public object HoldingObject { get { return _holdingObject; } set { if (_holdingObject != value) { _holdingObject = value; NotifyPropertyChanged("HoldingObject"); // Notify from the property that is being checked NotifyPropertyChanged("IsHoldingObject"); } } } public bool IsHoldingObject { get { return this.HoldingObject == null; } } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; private void NotifyPropertyChanged(string propertyName) { if (this.PropertyChanged != null) this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } #endregion } Case (B) - Notify IsHoldingObject changed from the IsHoldingObject directly, by setting it to false or true from HoldingObject property: public class NotifyingClass2 : INotifyPropertyChanged { private object _holdingObject; public object HoldingObject { get { return _holdingObject; } set { if (_holdingObject != value) { _holdingObject = value; NotifyPropertyChanged("HoldingObject"); // 1) Set the property here this.IsHoldingObject = _holdingObject != null; } } } private bool _isHoldingObject; public bool IsHoldingObject { get { return _isHoldingObject; } set { if (_isHoldingObject != value) { _isHoldingObject = value; // 2) Notify directly from the property NotifyPropertyChanged("IsHoldingObject"); } } } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; private void NotifyPropertyChanged(string propertyName) { if (this.PropertyChanged != null) this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } #endregion } I personally lean to the first one because it requires less code, but I'm not sure how recommendable it is to do that. Let me know if there is another (better) way. Thanks!

  • Using java to create a logistic model - arrays and properties

    - by Oliver Burdekin
    I'm currently trying to create a java model that will solve a problem we have. On a voluntary expedition each week we have some people leaving and some new people arriving. Accommodation is in tents. The tents sleep different numbers of people and certain rules apply. Males and females cannot be mixed and volunteers can be one of four types - school children/ research assistants/ scientific staff/ school teachers So types of volunteer and sexes cannot be mixed. Each week the manager spends hours trying to work this out so I've offered to make this model to keep my coding skills up. At present I'm working with arrays. Each tent is a 2D array [4][x] where x is the number of people it sleeps (each person sleeping there has 4 attributes). Each person is a 1D array with 4 attributes [4]. The idea is to check where people can go, cause the minimum movement for people staying on and solve this logistic problem. Does anyone have any better suggestions as to how to solve this? At present I'm finding it necessary to write a lot of code setting up and querying arrays. Any help is appreciated.

  • When I try to pass large amounts of information using jquery $.ajax(post) method. it throws potenti

    - by dotnetrocks
    I am trying to create a preview window for my texteditor in my blog page. I need to send the content to the server to clean up the text entered before I can preview it on the preview window. I was trying to use $.ajax({ type: method, url: url, data: values, success: LoadPageCallback(targetID), error: function(msg) { $('#' + targetID).attr('innerHTML', 'An error has occurred. Please try again.'); } }); Whenever I tried to click on the preview button it returns an XMLHTTPRequest error. The error description - Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. The ValidateRequest for the page is set to false. Is there a way I can set validaterequest to false for the ajax call.Please advise Thank you for reading my post.

  • UpdatePanel reloads the whole page

    - by Emil D
    Hi.I'm building an asp.net cutom control inside which I have two dropdownlists: companyIdSelection and productFamilySelection.I populate the companyIdSelection at Page_Load and in order to populate the productFamilySelection depending on the selected item in companyIdSelection.I'm using UpdatePanels to achieve this, but for some reason every time I update companyIdSelection Page_Load is being called ( which as far as I know should happen only when the entire page is reloaded ), the list is being reloaded again and the item the user selected is lost( the selected item is always the top one ).Here's the code <asp:UpdatePanel ID="updateFamilies" runat="server" UpdateMode="Always"> <ContentTemplate> Company ID:<br> <br></br> <asp:DropDownList ID="companyIdSelection" runat="server" AutoPostBack="True" OnSelectedIndexChanged="companyIdSelection_SelectedIndexChanged"> </asp:DropDownList> <br></br> Product Family: <br></br> <asp:DropDownList ID="productFamilySelection" runat="server" AutoPostBack="True" onselectedindexchanged="productFamilySelection_SelectedIndexChanged"> </asp:DropDownList> <br> </ContentTemplate> </asp:UpdatePanel> protected void Page_Load(object sender, EventArgs e) { this.companyIdSelection.DataSource = companyIds(); //companyIds returns the object containing the initial data items this.companyIdSelection.DataBind(); } protected void companyIdSelection_SelectedIndexChanged(object sender, EventArgs e) { // Page_Load is called again for some reason before this method is called, so it // resets the companyIdSelection EngDbService s = new EngDbService(); productFamilySelection.DataSource = s.getProductFamilies(companyIdSelection.Text); productFamilySelection.DataBind(); } Also, I tried setting the UpdateMode of the UpdatePanel to "Conditional" and adding an asyncpostback trigger but the result was the same. What am I doing wrong? PS: I fixed the updating problem, by using Page.IsPostBack in the Page_Load method, but I would still want to avoid a full postback if possible

  • Behavior of Struts2 and convention-plugin when there is Index(extends ActionSupport)

    - by hanishi
    We have an Action class named 'Index' immediately under com.example.common.action and is annotated @ParentPackage('default') which is declared in package directive in struts.xml and has "/" for its namespace and extends "struts-default". It also declares @Result so that it responses with jsp files corresponding the string values returned by its execute() method. In our struts.xml, the following struts setting is configured along with other necessary configurations that are needed for convention-plugin. <constant name="struts.action.extension" value=","/> When accessing /my_context/none_existing_path, the request apparently hits this Index class and the contents of the jsp declared in the Index's @Result section gets returned. However, if we provide /my_context/, we receive the following error: HTTP Status 404-There is no Action mapped for namespace[/] and action name [] associated with context path [/my_context]. We want to know the reason why accessing /my_context/none_existing_path, where none_existing_path has no matching action, can fallback to Index class, but error is returned when when the URL requested is just /my_context/. Currently, our convention-plugin settings are declared as follows: <constant name="struts.convention.package.locators.basePackage" value="com.example"/> <constant name="struts.convention.package.locators" value="action"/> Strangely, if we changed the value of the struts.convention.package.locators.basePackage to om.example.common, in which the aforementioned Index file can be immediately found by narrowing the search scope, requesting /my_context/ displays the content of the jsps declared in @Result section of the Index class. However, as our action classes are distributed throughout the com.example.[a-z].action packages, where [a-z] represents the large volume of directories we have in our package structure, we cannot use this trick as a workaround. We have also tried placing index.jsp at the top level of the class path, and have the index.jsp redirect to /my_context/index, which worked but not what we want. Could this be a bug? We appreciate your responses. Thank you in advance. EDIT: JIRA registered, problem solved (from Struts 2.3.12 up)

  • @dynamic property needs setter with multiple behaviors

    - by ambertch
    I have a class that contains multiple user objects and as such has an array of them as an instance variable: NSMutableArray *users; The tricky part is setting it. I am deserializing these objects from a server via Objective Resource, and for backend reasons users can only be returned as a long string of UIDs - what I have locally is a separate dictionary of users keyed to UIDs. Given the string uidString of comma separated UIDs I override the default setter and populate the actual user objects: @dynamic users; - (void)setUsers:(id)uidString { users = [NSMutableArray arrayWithArray: [[User allUsersDictionary] objectsForKeys:[(NSString*)uidString componentsSeparatedByString:@","]]]; } The problem is this: I now serialize these to database using SQLitePO, which stores these as the array of user objects, not the original string. So when I retrieve it from database the setter mistakenly treats this array of user objects as a string! Where I actually want to adjust the setter's behavior when it gets this object from DB vs. over the network. I can't just make the getter serialize back into a string without tearing up large code that reference this array of user objects, and I tried to detect in the setter whether I have a string or an array coming in: if ([uidString respondsToSelector:@selector(addObject)]) { // Already an array, so don't do anything - just assign users = uidString but no success... so I'm kind of stuck - any suggestions? Thanks in advance!

  • Attempting to calculate width of Map Overlays on the fly

    - by Bloudermilk
    Hey all- I am working on an Android app that utilizes the Google Maps API MapView, MapController, MapActivity, and ItemizedOverlay. I am basically trying to recreate certain functionalities of the Maps app (damn Google for not providing speech bubbles—for lack of a better name—for items!), particularly those speech bubbles. I have an invisible XML structure for the speech bubble in the XML layout file containing my MapView. The first time I show a speech bubble I grab that XML and remove it from it's current parent, applying some ItemizedOverlay.LayoutParams to it, and add it to the MapView as an Overlay. I position it above the item that was selected, fill it with the proper text, then set it to visible. This all works great. The goal here, though, is to also automatically animate the map to reveal any parts of a speech bubble that may be off-screen when it opens. So I'm trying popup.getWidth() (popup is the instance of my LinearLayout that is the speech bubble) after I do all the manipulation to the bubble, even after I display it to the user. Problem is, popup.getWidth() is returning me the width of the previously displayed popup, not the currently displayed one. I can't figure out why this would be happening if I'm fetching the width after I set it to visible with its new dimensions (which, by the way, are relative when I'm setting them with LayoutParams: fill_content for both width and height).. I have even tried forcing both the MapView and the "popup" to invalidate() before trying to fetch the width. Any ideas why this may be happening? How can I force the View to settle into its new dimensions before trying to fetch them? Thanks! Nick

  • Doxygen including methods twice doc files

  • initialise a var in scala

    - by user unknown
    I have a class where I like to initialize my var by reading a configfile, which produces intermediate objects/vals, which I would like to group and hide in a method. Here is the bare minimum of the problem - I call the ctor with a param i, in reality a File to parse, and the init-method generates the String s, in reality more complicated than here, with a lot of intermediate objects being created: class Foo (val i: Int) { var s : String; def init () { s = "" + i } init () } This will produce the error: class Foo needs to be abstract, since variable s is not defined. In this example it is easy to solve by setting the String to "": var s = "";, but in reality the object is more complex than String, without an apropriate Null-implementation. I know, I can use an Option, which works for more complicated things than String too: var s : Option [String] = None def init () { s = Some ("" + i) } or I can dispense with my methodcall. Using an Option will force me to write Some over and over again, without much benefit, since there is no need for a None else than to initialize it that way I thought I could. Is there another way to achieve my goal?

  • wxpython - Running threads sequentially without blocking GUI

    - by ryantmer
    I've got a GUI script with all my wxPython code in it, and a separate testSequences module that has a bunch of tasks that I run based on input from the GUI. The tasks take a long time to complete (from 20 seconds to 3 minutes), so I want to thread them, otherwise the GUI locks up while they're running. I also need them to run one after another, since they all use the same hardware. (My rationale behind threading is simply to prevent the GUI from locking up.) I'd like to have a "Running" message (with varying number of periods after it, i.e. "Running", "Running.", "Running..", etc.) so the user knows that progress is occurring, even though it isn't visible. I'd like this script to run the test sequences in separate threads, but sequentially, so that the second thread won't be created and run until the first is complete. Since this is kind of the opposite of the purpose of threads, I can't really find any information on how to do this... Any help would be greatly appreciated. Thanks in advance! gui.py import testSequences from threading import Thread #wxPython code for setting everything up here... for j in range(5): testThread = Thread(target=testSequences.test1) testThread.start() while testThread.isAlive(): #wait until the previous thread is complete time.sleep(0.5) i = (i+1) % 4 self.status.SetStatusText("Running"+'.'*i) testSequences.py import time def test1(): for i in range(10): print i time.sleep(1) (Obviously this isn't the actual test code, but the idea is the same.)

  • Java program will read from database, but not write to it

    - by ck1221
    I have a Java program that successfully connects to a mysql database that is hosted on godaddy's server. I can read from that db with out issue, however, when I try to write to it with INSERT or UPDATE for example, the query does not execute. I am using the 'admin' account that I set up through godaddy, I realize this is not the root account. I have checked and verified that the connection is not read only, and have logged out of phpmyadmin while the query ran. I'm not sure what else I can try or if anyone has experienced this issue. Maybe a setting to the connection I have failed to set? Or maybe its not possible since the db is hosted on godaddy's servers? Any help is great! Thanks. Here is some relevant code: Connection to db: Connection con; public DBconnection(String url, String user, String pass) { try { Class.forName("com.mysql.jdbc.Driver").newInstance(); con = DriverManager.getConnection (url,user,pass); if(!con.isClosed()) System.out.println("connecton open"); } catch (InstantiationException e) {e.printStackTrace();} catch (IllegalAccessException e) {e.printStackTrace();} catch (ClassNotFoundException e) {e.printStackTrace();} catch (SQLException e) {e.printStackTrace();} } Send Query: public ResultSet executeQuery(String query) { ResultSet rs = null; try { Statement stmt = (Statement) con.createStatement(); rs = stmt.executeQuery(query); //while(rs.next()) //System.out.println(rs.getString("ticket_num")); } catch (SQLException e) {} return rs; } Insert Query (works in phpmyadmin): conn.executeQuery("INSERT INTO tickets VALUES(55555,'12/01/2012','me','reports','test','','','0','Nope')");

  • What would be a better implementation of shared variable among subclass

    - by Churk
    So currently I have a spring unit testing application. And it requires me to get a session cookie from a foreign authentication source. Problem what that is, this authentication process is fairly expensive and time consuming, and I am trying to create a structure where I am authenticate once, by any subclass, and any subsequent subclass is created, it will reuse this session cookie without hitting the authentication process again. My problem right now is, the static cookie is null each time another subclass is created. And I been reading that using static as a global variable is a bad idea, but I couldn't think of another way to do this because of Spring framework setting things during run time and how I would set the cookie so that all other classes can use it. Another piece of information. The variable is being use, but is change able during run time. It is not a single user being signed in and used across the board. But more like a Sub1 would call login, and we have a cookie. Then multiple test will be using that login until SubX will come in and say, I am using different credential, so I need to login as something else. And repeats. Here is a outline of my code: public class Parent implements InitializingBean { protected static String BASE_URL; public static Cookie cookie; ... All default InitializingBean methods ... afterPropertiesSet() { cookie = // login process returns a cookie } } public class Sub1 extends Parent { @resource public String baseURL; @PostConstruct public void init() { // set parents with my baseURL; BASE_URL = baseURL; } public void doSomething() { // Do something with cookie, because it should have been set by parent class } } public class Sub2 extends Parent { @resource public String baseURL; @PostConstruct public void init() { // set parents with my baseURL; BASE_URL = baseURL; } public void doSomethingElse() { // Do something with cookie, because it should have been set by parent class } }

  • How can I make VS2010 insert using statements in the order dictated by StyleCop rules.

    - by Hamish Grubijan
    The related default StyleCop rules are: Place using statements inside namespace. Sort using statements alphabetically. But ... System using come first (still trying to figure out if that means just using System; or using System[.*];). So, my use case: I find a bug and decide that I need to at least add an intelligible Assert to make debugging less painful for the next guy. So I start typing Debug.Assert( and intellisense marks it in Red. I hover mouse over Debug and between using System.Diagnostics; and System.Diagnostics.Debug I choose the former. This inserts using System.Diagnostics; after all other using statements. It would be nice if VS2010 did not assist me in writing code that won't build due to warnings as errors. How can I make VS2010 smarter? Is there some sort of setting, or does this require a full-fledged add-in of some sort?

  • Why is passing a string literal into a char* argument only sometimes a compiler error?

    - by Brian Postow
    I'm working in a C, and C++ program. We used to be compiling without the make-strings-writable option. But that was getting a bunch of warnings, so I turned it off. Then I got a whole bunch of errors of the form "Cannot convert const char* to char* in argmuent 3 of function foo". So, I went through and made a whole lot of changes to fix those. However, today, the program CRASHED because the literal "" was getting passed into a function that was expecting a char*, and was setting the 0th character to 0. It wasn't doing anything bad, just trying to edit a constant, and crashing. My question is, why wasn't that a compiler error? In case it matters, this was on a mac compiled with gcc-4.0. EDIT: added code: char * host = FindArgDefault("EMailLinkHost", ""); stripCRLF(linkHost, '\n'); where: char *FindArgDefault(char *argName, char *defVal) {// simplified char * val = defVal; return(val); } and void stripCRLF(char *str, char delim) { char *p, *q; for (p = q = str; *p; ++p) { if (*p == 0xd || *p == 0xa) { if (p[1] == (*p ^ 7)) ++p; if (delim == -1) *p = delim; } *q++ = *p; } *q = 0; // DIES HERE } This compiled and ran until it tried to set *q to 0...

  • Silverlight Timer problem

    - by jose
    Hello, I am developing a Silverlight application with custom animations. I want to update the variable animationCounter every 1 milissecond, so that in one second the value is 1000. I've tried DispatcherTimer and System.Threading.Timer. this way: DispatcherTimer timer = new DispatcherTimer(); (...) timer.Interval = new TimeSpan(0, 0, 0, 0, 1); timer.Tick += new EventHandler(timer_Tick); (...) (...) void timer_Tick(object sender, EventArgs e) { animationCounter++; Dispatcher.BeginInvoke(() => txtAnimationCounter.Text = animationCounter.ToString()); } with System.Threading.Timer System.Threading timer = null; timer = new System.Threading.Timer(UpdateAnimationCounter, 0, 1); void UpdateAnimationCounter(object state) { animationCounter++; Dispatcher.BeginInvoke(() => txtAnimationCounter.Text = animationCounter.ToString()); } Both of them are setting AnimationCounter around 100 in one second. Should be 1000. I don't know why. Is there anything I'm missing. Thanks

  • How to set JComboBox not to select an element when created? (Java)

    - by Alex Cheng
    Hi all. Problem: I am using JComboBox, and tried using setSelectionIndex(-1) in my code (this code is placed in caretInvoke()) suggestionComboBox.removeAllItems(); for (int i = 0; i < suggestions.length; i++) { suggestionComboBox.addItem(suggestions[i]); } suggestionComboBox.setSelectedIndex(-1); suggestionComboBox.setEnabled(true); This is the initial setting when it was added to a pane: suggestionComboBox = new JComboBox(); suggestionComboBox.setEditable(false); suggestionComboBox.setPreferredSize(new Dimension(25, 25)); suggestionComboBox.addActionListener(new SuggestionComboBoxListener()); When the caretInvoke triggers the ComboBox initialisation, even before the user selects an element, the actionPerformed is already triggered (I tried a JOptionPane here): First popup (notice that "flow byte_jump" is selected): Second popup (I think the setSelectionIndex is executed) Then in the end: The problem is: My program autoinserts the selected text when the user selects an element from the ComboBox. So without the user selecting anything, it is automatically inserted already. How can I overcome the problem in this situation? Thanks.

    - by CSFYPMAIL
    Basically I'm creating an indoor navigation system in J2ME. I've put the location details in a .txt file i.e. Locations names and their coordinates. Edges with respective start node and end node as well as the weight (length of the node). I put both details in the same file so users dont have to download multiple files to get their map working (it could become time consuming and seem complex). So what i did is to seperate the deferent details by typing out location Names and coordinates first, After that I seperated that section from the next section which is the edges by drawing a line with multiple underscores. Now the problem I'm having is parsing the different details into seperate arrays by setting up a command (while manually tokenizing the input stream) to check wether the the next token is an underscore. If it is, (in pseudocode terms), move to the next line in the stream, create a new array and fill it up with the next set of details. I found a some explanation/code HERE that does something similar but still parses into one array, although it manually tokenizes the input. Any ideas on what to do? Thanks Text File Explanation The text has the following format... <--1stSection--  /**   * Section one has the following format   * xCoordinate;yCoordinate;LocationName   */ 12;13;New York City 40;12;Washington D.C. ...e.t.c _________________________ <--(underscore divider) <--2ndSection--  /**   * Its actually an adjacency list but indirectly provides "edge" details.   * Its in this form   * StartNode/MainReferencePoint;Endnode1;distance2endNode1;Endnode2;distance2endNode2;...e.t.c   */ philadelphia;Washington D.C.;7;New York City;2 New York City;Florida;24;Illinois;71 ...e.t.c

  • How to configure an index.htm file in IIS?

    - by salvationishere
    I am running IIS 6.0 on an XP OS using VS 2008 and SQL Server 2008 (Full install). I developed two web apps. Both of these I can run from IIS by setting them to the default website. However, now I tried adding an index.htm file. Real simple; all it has is two hyperlinks to these web apps. But now only the first web app works. The first web app is pure VS. The second web app modifies an Adventureworks database table. But now when I click the hyperlink for the second web app, it gives me the error below. However this error doesn't make sense to me cause I have the two web apps configured as two virtual directories beneath C:\inetpub\ and the index.htm file is also beneath C:\inetpub. And the default website is set to home directory C:\inetpub\ with Document index.htm on top. Also, why does the first web app work and not the second now? Server Error in '/AddFileToSQL' Application. The path '/AddFileToSQL/App_GlobalResources/' maps to a directory outside this application, which is not supported. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Web.HttpException: The path '/AddFileToSQL/App_GlobalResources/' maps to a directory outside this application, which is not supported.

  • Upgrade to iPhone 3.0 sdk and now simulator shows blank screen.

    - by NoShitMcGee
    I have an iPhone app that uses an UITabBarController, which contains two UINavigationControllers, each of which in turn contains one or more TableViewControllers (actually, customized UIViewControllers implementing UITableViewDelegate and UITableViewDataSource. ) On launch, it displays the UITabBarController with one of the tableviews displayed. Everything is coded; Interface Builder was NOT used to make any of the UI stuff. It was written in SDK 2. It worked fine in sdk 2. I recently updated to SDK 3.0. In Info, I set the Base SDK setting to iPhone Simulator 3.0. Now, when I launch the application in Simulator, I see only a blank white screen with the status bar at the top. No signs of my app. However, when I exit the app, the missing tableview displays briefly as the exiting animation is playing. Also, on the blank white screen I can still click where the navigation buttons should be and find that, when I exit the app and the missing screen briefly displays, that navigation has taken me to another screen. So the buttons work, and presumably the tableviewcells are there, they just cannot be seen. Has anyone seen anything like this? Does anyone have any idea what is causing it and how I can fix it? I noticed that sample apps, such as SQLiteBooks, seem to work fine when updating to SDK 3.0. My app isn't very much different from SQLiteBooks in terms of technologies used, except that, as I said above, I do not use Interface Builder. Thanks

  • jQuery selector selecting all rows... why?

    - by Jagd
    I have a standard HTML table that looks something like this in structure: <table> <tbody> <tr> <td>FOOTER</td> <td> ... other td columns </td> </tr> <tr> <td>some other row that I don't want selected</td> <td> ... other td columns </td> </tr> </tbody> </table> What I would like to do is select only the tr's that contain the text FOOTER in a td, and then set the font-weight to bold for all td's under the selected tr's. My problem is that the jQuery selector I have is setting all td's within the table to bold and I'm not sure why. Here's my selector thus far: $("tr:contains('FOOTER')").children("td").css("font-weight", "bold");
