  • Trouble defining a variable in PHP?

    - by Jake
    Alright, so a content page uses this: $tab = "Friends"; $title = "User Profile"; include '(the header file, with nav)'; And the header page has the code: if ($tab == "Friends") { echo '<li id="current">'; } else { echo '<li>'; } The problem is, that the if $tab == Friends condition is never activated, and no other variables are carried from the the content page, to the header page. Does anyone know what I'm doing wrong? Update: Alright, the problem seemed to disappear when I used ../scripts/filename.php, and only occurred when I used a full URL? Any ideas why?

  • NSTimer freezes the app until it gets fired again?

    - by itai alter
    Hello all, I have a simple app with a button, UIImageView and a NSTimer. The timer is fired up every 5 seconds repeatedly to update the ImageView with a new image, while the button simply stops the timer and switches to another View. The problem is that when I press the button, nothing happens for a few seconds (until the timer fires up again). Is there a way to cause the button to stop the timer and do its job at any given time instead of between intervals of the timer? Thanks!

  • Performing AJAX calls on the "new" controller

    - by shmichael
    In my rails app, I want to have a sortable list as part of an object creation. The best practice suggested Railscast adds the acts_as_list plugin and then initiates AJAX calls to update item position. However, AJAX calls won't work on an unsaved model, which is the situation with new. One solution would be to save the model immediately on new and redirect to edit. This would have a nice side effect of persisting any change so the user could resume work should he be interrupted. However, this solution adds the unwanted complexity of saving an invalid model, compromising rails' validation processes. Is there any better way to allow AJAX + validations without going into too much work?

  • What are the pros and cons to keeping SQL in Stored Procs versus Code

    - by Guy
    What are the advantages/disadvantages of keeping SQL in your C# source code or in Stored Procs? I've been discussing this with a friend on an open source project that we're working on (C# ASP.NET Forum). At the moment, most of the database access is done by building the SQL inline in C# and calling to the SQL Server DB. So I'm trying to establish which, for this particular project, would be best. So far I have: Advantages for in Code: Easier to maintain - don't need to run a SQL script to update queries Easier to port to another DB - no procs to port Advantages for Stored Procs: Performance Security

  • Intermittent "No Database Selected" in PHP/MySQL?

    - by ANE
    Have a PHP/MySQL form with a dropdown box containing a list of 350 names. When any random name is selected, sometimes it works & displays info about that name from the database, and sometimes the form gives the error "No Database Selected". Here's what I've tried, pretty much grasping at straws as I'm not a programmer: Increasing max_connections in /etc/my.cnf from 200 to 2000 (even though only 4-5 connections are made and it's a lightly used server) Changing mysql_pconnect to mysql_connect Adding the word true to this connection string: $mysql = mysql_pconnect($hostname_mysql, $username_mysql, $password_mysql, true) or trigger_error(mysql_error(),E_USER_ERROR); Changing the word require_once to require on this line: [?php require('/home/user/Connections/mysql.php'); ?] Enabling MySQL & PHP query & error logging. (no errors logged) Here is the code: [removed old bad code] Update: Working answer from Rob Apodaca below.

  • Build an unbound form in Acess 2007

    - by DoubleJ92
    I have an access application that has a form that allows the user to enter case notes. The main field of this form is tied to a SQL Server varchar(MAX) field in the source table. Since the users switched to Access 2007, their program keeps crashing when they are on the case notes form. As a possible solution to this problem, I would like to try unbinding this form and re-building it as an unbound form. This form needs to be able to add and update records into my SQL Server database. It also needs to be able to browse between records. I guess I am at a loss as to where to start. Any suggestions/code snippets is appreciated.

  • How do i make an installer instead of a crash (.NET)

    - by acidzombie24
    My situation is Using .NET 3.5 Using SDL.NET Need to make a friendly installer or warning system. Chances are the user will be on XP (.NET 1.1). If possible can i do something to let the user know he needs to update to 3.5? Maybe have a yes/no dialog which downloads and install the .NET runtimes for him? Now how do i detect if the user has sdl.net installed (chances are its in program files/sdldotnet) and let them know they need sdl.net runtime and have a yes/no dialog that brings them to http://sourceforge.net/projects/cs-sdl/files/ The problem i have mostly is how to make the app not outright crash and how to download 3.5 .NET runtime if it is possible.

  • Best Way to Generate Unique and consecutives numbers in Oracle

    - by RRUZ
    I need to generate unique and consecutive numbers (for use on an invoice), in a fast and reliable way. currently use a Oracle sequence, but in some cases generated numbers are not consecutive because of exceptions that may occur. I thought a couple of solutions to manage this problem, but neither of they convincing me. What solution do you recommend? Use a select max () SELECT MAX (NVL (doc_num, 0)) +1 FROM invoices Use a table to store the last number generated for the invoice. UPDATE docs_numbers SET last_invoice = last_invoice + 1 Another Solution?

  • Does a C# using statement perform try/finally?

    - by Lirik
    Suppose that I have the following code: private void UpdateDB(QuoteDataSet dataSet, Strint tableName) { using(SQLiteConnection conn = new SQLiteConnection(_connectionString)) { conn.Open(); using (SQLiteTransaction transaction = conn.BeginTransaction()) { using (SQLiteCommand cmd = new SQLiteCommand("SELECT * FROM " + tableName, conn)) { using (SQLiteDataAdapter sqliteAdapter = new SQLiteDataAdapter()) { sqliteAdapter.Update(dataSet, tableName); } } transaction.Commit(); } } } The C# documentation states that with a using statement the object within the scope will be disposed and I've seen several places where it's suggested that we don't need to use try/finally clause. I usually surround my connections with a try/finally, and I always close the connection in the finally clause. Given the above code, is it reasonable to assume that the connection will be closed if there is an exception?

  • Specification: Use cases for CRUD

    - by Mario Ortegón
    I am writing a Product requirements specification. In this document I must describe the ways that the user can interact with the system in a very high level. Several of these operations are "Create-Read-Update-Delete" on some objects. The question is, when writing use cases for these operations, what is the right way to do so? Can I write only one Use Case called "Manage Object x" and then have these operations as included Use Cases? Or do I have to create one use case per operation, per object? The problem I see with the last approach is that I would be writing quite a few pages that I feel do not really contribute to the understanding of the problem. What is the best practice?

  • What's the best Java-based forum software?

    - by SamS
    Somebody asked about .NET-based forum software here: http://stackoverflow.com/questions/11046/forum-software-recommandations-net Now I have a similar question but I prefer Java. I'm interested in building a community site so I'd like to know my options. It doesn't have to be free but it needs to be something a normal engineer can afford. Thanks! Update: I prefer a Java-based solution because I'm a Java developer and I figure that it would be easier for me to customize it or modify its code when necessary. I know that PHP forums such as phpBB and vBulletin are very popular but I wouldn't want to touch PHP code.

  • How do you deal with the conflict between ActiveSupport::JSON and the JSON gem?

    - by Luke Francl
    I am stumped with this problem. ActiveSupport::JSON defines to_json on various core objects and so does the JSON gem. However, the implementation is not the same -- the ActiveSupport version takes arguments and the JSON gem version doesn't. I installed a gem that required the JSON gem and my app broke. The issue is that I'm using to_json in a controller that returns a list of objects, but I want to control which attributes are returned. When code anywhere in my system does require 'json' I get this error message: TypeError: wrong argument type Hash (expected Data) I tried a couple of things that I read online to fix it, but nothing worked. I ended up re-writing the gem to use ActiveSupport::JSON.decode instead of JSON.parse. This works but it's not sustainable...I can't be forking gems every time I want to use a gem that requires the JSON gem. Update: The best solution of this problem is to upgrade to Rails 2.3 or higher, which fixed it.

  • Tools and ways to generate HTML help for built-in help system (QtHelp)?

    - by BastiBense
    Hello, I'm in the progress of implementing a built-in help system based on QtHelp into my application. Since QtHelp is based on Qt's help collection files, I need to produce a set of HTML pages. Since I won't be writing the documentation alone (a few of my colleagues will write, too), I am looking for the best way to produce these files. We are internally using a Wiki, and I know that the documentation should be written in some kind of markup language instead of giving all authors a WYSIWYG HTML editor. So my question is, are there tools out there which help with the process of generating documentation that can be exported as a set of HTML files, and possibly, as PDFs, too?. Thanks in advance! Update: I'm already using Doxygen for C++ documentation generation. But I'm not exactly looking for an API-Documentation generator, but something like LaTeX, which allows you to format the documentation contents like a markup document (much like a Wiki).

  • Show javascript execution progress

    - by Midhat
    I have some javascript functions that take about 1 to 3 seconds. (some loops or mooML templating code.) During this time, the browser is just frozen. I tried showing a "loading" animation (gif image) before starting the operation and hiding it afterwords. but it just doesnt work. The browser freezes before it could render the image and hides it immediately when the function ends. Is there anything I can do to tell the browser to update the screen before going into javascript execution., Something like Application.DoEvents or background worker threads. So any comments/suggestions about how to show javascript execution progress. My primary target browser is IE6, but should also work on all latest browsers

  • Automatic Hudson CI setup and plugin updates through apt?

    - by aapeli
    Hi! We've used Hudson for quite a while to implement a CI server with all the bells and whistles. The setup is quite straight forward, when installing from the provided RPMs and Debs, but through googling I haven't been able to figure out whether the plugins are installable using apt/rpm or some other package manager? The reason is that I would like to create a (meta)package for Ubuntu which would install and also update both Hudson and all the plugins through the normal upgrade mechanism. At the same time I could create a template setup for other projects, say JavaEE project needs git, cobertura and Chuck Norris plugins, while my Python project needs plugins XXX and YYY. Anybody got such a setup? As a workaround I figured setting up a number of Maven POMs, which would do the init, and later upgrades, but I feel this would require more scripting on the side, which I'm not very eager to do. Any other suggestions for this would also be appreciated.

  • Google Map Overlay Icon disappears at certain zoom level

    - by Lawrence Teo
    I notice that Firefox 3 demonstrates this problem. I put down an overlay icon and play around with the map zoom. At certain zoom level, I found that the icon disappears for some unknown reason. Zooming out brings back the icon. Or during the disappearance, I click on the Google Map and it will somehow trigger to bring back the icon. I suspect it has something to do with the event triggering. Internet Explorer doesn't demonstrate the same problem though. Any advice? Like how to trigger update event on Firefox?

  • Question About DateCreated and DateModified Columns - MS SQL Server

    - by user311509
    CREATE TABLE Customer ( customerID int identity (500,20) CONSTRAINT . . dateCreated datetime DEFAULT GetDate() NOT NULL, dateModified datetime DEFAULT GetDate() NOT NULL ); When i insert a record, dateCreated and dateModified gets set to default date/time. When i update/modify the record, dateModified and dateCreated remains as is? What should i do? Obviously, i need to dateCreated value to remain as was inserted the first time and dateModified keeps changing when a change/modification occurs in the record fields. In other words, can you please write a sample quick trigger? I don't know much yet... Any help will be appreciated.

  • Using property file in hibernate mapping

    - by Zoltan Hamori
    Hi, I have a two nodes environment using the same database. In the database there is a resource table like RESOURCE_ID, CODE, NODE The content of the NODE column can be 1 or 2 depending on which node can use it. As I need to deploy the same ear to the two nodes, I would like to map this table like this: <hibernate-mapping> <class name="ResourceVO" table="RESOURCE" dynamic-update="true" optimistic-lock="dirty" where="NODE=${node.value}" > I would like to store the node.value property on the file system, so the instances could identify which resource to use. Is it possible in hibernate?

  • Increasing number once per mouse click/key press in XNA

    - by DMan
    This has been bothering me lately- when I use some code like below to increase selection every mouse click: if (m.LeftButton == ButtonState.Pressed) currentSelection++; Then currentSelection increases by a ton, simply because this code is in my Update() function and by design, runs every frame and so increases currentSelection. There is almost no chance you can click and release fast enough to prevent currentSelection from increasing more than one. Now my question is what I should do to make it so everytime I click the mouse down once, it only increases currentSelection once until the next time I click down again.

  • how does fgets internally works?

    - by Registered User
    Well it is a basic question but I seem confused enough. #include<stdio.h> int main() { char a[100]; printf("Enter a string\n"); scanf("%s",a); } Basically the above is what I want to achieve. If I enter a string James Bond then I want that to be stored in array a. But the problem is because of presence of a blank space in between only James word is stored. So how can I solve this one. UPDATE After the replies given below I understand fgets() would be a better choice. I want to know internal working of fgets as why is it able to store the string with space where as scanf is not able to do the same.

  • Invoke an action that is using ASP.NET MVC [Authorize] from outside the application

    - by Nate Bross
    Is this possible? I'd like to expose a URL (action) such as http://mysever/myapp/UpdateHeartbeat/. In my MVC application it looks like [Authorize] [AcceptsVerbs(HttpVerbs.Post)] public ActionResult UpdateHeartbeat() { // update date in DB to DateTime.Now } Now, in my MVC application the user has logged in via FORMS authentication and they can execute that action to their hearts content. What I want to do, is hit that URL progromatically (as part of an API that I wouldl like to build) -- is there a way I can do that without removing the [Authorize] attribute and adding username/password as parameters to the POST?

  • Design Code Outside of an IDE (C#)?

    - by ryanzec
    Does anyone design code outside of an IDE? I think that code design is great and all but the only place I find myself actually design code (besides in my head) is in the IDE itself. I generally think about it a little before hand but when I go to type it out, it is always in the IDE; no UML or anything like that. Now I think having UML of your code is really good because you are able to see a lot more of the code on one screen however the issue I have is that once I type it in UML, I then have to type the actual code and that is just a big duplicate for me. For those who work with C# and design code outside of Visual Studio (or at least outside Visual Studio's text editor), what tools do you use? Do those tools allow you to convert your design to actual skeleton code? It is also possible to convert code to the design (when you update the code and need an updated UML diagram or whatnot)?
