• Preserving text formatting for dynamic website

  - by Mohit

  Hello Folks, I am facing a problem while creating a dynamic website. I am building it for some pharma company, which have many products. The problem is, every product have different sections of description, and have to be formatted differently. I wanted to store all the product descriptions in the database, but at the same time preserve the formatting of each description. I also plan to provide an admin interface, where they could edit the product information themselves. I could use Joomla or any other CMS for that purpose, but i wanted to know if i want to build such a system of my own, where i could format the text in an editor and them save that thing into database and when i retrieve it, i get the same formatting. How could i do this? Also i wanted to do this in PHP. Thanks -- Mohit

• Export from HTML to PDF (C#)

  - by Sem Dendoncker

  Hi, In our applications we make html documents as reports and exports. But now our customer wants a button that saves that document on their pc. The problem is that the document includes images. You can create a word document with the following code: private void WriteWordDoc(string docName) { Response.Buffer = true; Response.ContentType = "application/msword"; Response.AddHeader("content-disposition", String.Format("attachment;filename={0}.doc", docName.Replace(" ", "_"))); Response.Charset = "utf-8"; } But the problem is that the images are just links an thus not embedded in the word document. Therefore I'm looking for an alternative PDF seems to be a good alternative, does anyone know a good pdf writer for C#? One that has some good references and has been tested properly? Best regards, Sem

• django urlconf or .htaccess trouble

  - by Zayatzz

  Hello I am running my django project from subfolder of a website. Lets say the address where my project is meant to open from is. http://example.com/myproject/ the myproject folder is root folder for my user account. In that folder i have fcgi script that starts my project. The .htaccess file in the folder contains this: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ mysite.fcgi/$1 [QSA,L] The trouble is, that at some cases, instead of redireting user to page like http://example.com/myproject/social/someurl/ it redirects to http://example.com/social/someurl/ which does not work. What i want to know is how to fix this problem. Is this django problem and i should change it with urconf and add myproject to all urls, or should i do this with .htaccess? I found similar question, which, sadly, remains unanswered: http://stackoverflow.com/questions/2321154/how-to-write-htaccess-if-django-project-is-in-subfolder-and-subdomain Alan.

• C# Winforms ADO.NET - DataGridView INSERT starting with null data

  - by Geo Ego

  I have a C# Winforms app that is connecting to a SQL Server 2005 database. The form I am currently working on allows a user to enter a large amount of different types of data into various textboxes, comboboxes, and a DataGridView to insert into the database. It all represents one particular type of machine, and the data is spread out over about nine tables. The problem I have is that my DataGridView represents a type of data that may or may not be added to the database. Thus, when the DataGridView is created, it is empty and not databound, and so data cannot be entered. My question is, should I create the table with hard-coded field names representing the way that the data looks in the database, or is there a way to simply have the column names populate with no data so that the user can enter it if they like? I don't like the idea of hard-coding them in case there is a change in the database schema, but I'm not sure how else to deal with this problem.

• Execute a function when a <link> element has finished loading

  - by nornagon

  I'm using jQuery Masonry to lay out my page, but I'm using a custom @font-face font. The problem being that Masonry doesn't know the metrics of the font until it's loaded. The Masonry docs suggest that you use $(window).load() instead of $(document).ready() to call the layout functions, but I don't want to have to wait until all the images etc. load. I can specify the dimensions of the images exactly, so Masonry doesn't need to wait until they're loaded. It's just the text that's the problem. How can I get jQuery to call a callback when the <link> element that links in the font finishes loading?

• Storing Interface type in ASP.NET Profile

  - by NathanD

  In my ASP.NET website all calls into the data layer return entities as interfaces and the website does not need to know what the concrete type is. This works fine, but I have run into a problem when trying to store one of those types into the user Profile. My interface implements ISerializable, like the following: public interface IInsured : IPerson, IEntity, ISerializable and the concrete type in the datalayer does implement ISerializable. My Profile property in web.config is: <add name="ActiveInsured" type="FacadeInterfaces.IInsured" serializeAs="Binary" defaultValue="[null]"/> It compiles just fine, but I get a runtime error on Profile.Save() saying that the interface cannot be serialized. I have also tried it with serializeAs="Xml". I thought that if my interface implemented ISerializable it would work. Anybody had this problem before or know of a workaround?

• Pass a variable to a Symfony Form

  - by Juan Besa

  Hi, I am building a web application using Symfony 1.4 and Doctrine for a school and I want to make a very simple form to add a course to a student. The main problem I have is that in the drop down list I only want to show the courses in which the student is currently not enrolled. I already have a function in the model (in Student.class.php) which returns all the courses in which the student is not enrolled but the problem is I don't know how to pass the student to the configure() of the form. I have tried several options like passing it with the constructor of the form to a global variable or a special set method but none of them have worked. Is there any form to pass the student to the configure() method? Thanks!

• Run a PHP-script from a PHP-script without blocking

  - by Nicklas Ansman

  I'm building a spider which will traverse various sites and data mining them. Since I need to get each page separately this could take a VERY long time (maybe 100 pages). I've already set the set_time_limit to be 2 minutes per page but it seems like apache will kill the script after 5 minutes no matter. This isn't usually a problem since this will run from cron or something similar which does not have this time limit. However I would also like the admins to be able to start a fetch manually via a HTTP-interface. It is not important that apache is kept alive for the full duration, I'm, going to use AJAX to trigger a fetch and check back once in a while with AJAX. My problem is how to start the fetch from within a PHP-script without the fetch being terminated when the script calling it dies. Maybe I could use system('script.php &') but I'm not sure it will do the trick. Any other ideas?

• Navigation bar's buttons tint color sometimes not set

  - by Felipe

  Refer to the following, short video: http://screencast.com/t/cmnsqVTh The problem is with the color of a navigation bar's back button. The first time I load the app, the navigation bar + its buttons have the default color. I then push a view controller on the stack, and when the new view loads (in the viewDidLoad method), it sets the navigation bar's tint color to pink. The nav bar's buttons are also pink as expected. I then press the back button, and the view is popped from the stack. On the root view controller's viewWillAppear method I set the tint color back to nil so that it's the default color again. The navigation bar looks as expected. However if I push the view controller on the stack yet again, the navigation bar's tint color is pink, but the back button's color is the default light blue. Hope that was understandable. So what's the cause of the problem?

• Subnav "active" when it shouldn't be.

  - by wilwaldon

  http://wilwaldon.com/itsbroken/templateleftnav.php As you can see on the left navigation the link for Template 01 is highlighted green. The link underneath is also highlighted green. I think the problem lies with the initial LI controlling the ul underneath somehow. I need to keep the xhtml formatted exactly how it is right now and only change the CSS to fix this problem. I'd appreciate any help you may be able to point me in the right direction, I'm pretty stuck at this point. Thank you in advance!

• SQL Server Reporting Services proxy timeout (ASP.NET)

  - by Philip

  Morning, We are using SSRS (2005) and have a ASP.NET frontend using the SSRS WebControl. I've boiled the problem down the time it takes for one particular report to be generated is greater than the timeout on the proxy server. It looks like the way the SSRS web control tries to do things is by performing an HTTP request for the report, however the problem with this is the request can timeout potentially before the report has generated. Looking at the HTTP traffic the response is a 504 (gateway timeout). Is there a way to increase the timeout or change SSRS WebControl to use more robust polling mechanism (which isn't dependant on the timeout of the HTTP request). I could be wrong but I don't think ServerReport.Timeout property would resolve the issue we are seeing? Any thoughts? Philip

• Issues with Ext-JS 1.1 date fields and Firefox 3.x / IE 8

  - by Cruachan

  I'm modifying an older website for a client that uses Ext-JS 1.1 and I'm having issues with display of date fields in IE and particularly Firefox. The site was left in a semi-implemented state previously, so there's not been a perceived problem before. In Chrome and Safari everything looks fine and the datepicker drops down and displays correctly. However in Firefox the picker is displayed widened to cover the maximum scrollable brower width (very wide indeed), and in IE it's truncated to about two thirds of the width it should be. I am somewhat uncertain that this is due to our css, but because Chrome and Safari work fine I think it might be a problem with Ext-js itself. I realise that this is an old version of Ext-JS, but because everything else works fine I don't want to go to the trouble of upgrading unless that would be very straightforward (but how difficult would that be?) I don't myself use ExtJS and this is the only website my client has with it - so I'm really looking for the simplest possible solution.

• WCF - calling back to client (duplex ?)

  - by MüllerDK

  Hi, I have a problem with what solution to choose.. I have a server running having a Service running that can receive orders from a website. To this server several client (remote computers) are connected somehow. I would really like to use WCF for all comunication, but not sure it's possible. I dont wanna configure all client firewall settings in their routers, so the clients would have to connect to the server. But when an order is recieved on the server, it should be transferred to a specific client. One solution could be to have the Client connect using a duplex binding, but it will have to somehow keep the connection alive in order to be able to received data from server... Is this a good way to do this ?? Normally the connection times out and probably for a good reason... Anyone have insight to this problem. Thx alot for any advise :-) Best Regards Søren Müller

• Adding a sortcomparefunction to Dynamic Data Grid in flex

  - by Tom

  Hi, I am trying to create a dynamic datagrid in Flex 3, I have a list of columns a list of objects which correspond to datapoints for those columns which I fetch from a url. While the grid works perfectly fine the problem is that sorting on the columns is done in lexical order. I am aware that this can be fixed by adding a sortcomparefunction to a column, which is not easy for this case. I have tried doing var dgc:DataGridColumn = new DataGridColumn(dtf); f1[dtf] = function(obj1:Object, obj2:Object):int { return Comparators.sortNumeric(obj1[dtf],obj2[dtf]); }; dgc.sortCompareFunction = f1[dtf];` But the problem is that the function object that I am creating here is being overwritten in every iteration (as I am adding columns) and eventually all the columns will have sorting done only on the last column added. Suggestions please.

• Monodevelop: `Waiting for debugger to connect...`

  - by Nicolas Raoul

  I am trying to debug this Mono desktop software in Monodevelop. I imported the SLN file, ran Build all with success, but when I press the Debug button I get this popup that stays waiting forever saying Waiting for debugger to connect...: The output says: User assembly '/home/nico/src/SparkleShare/SparkleShare/bin/SparkleShare.exe' is missing. Debugger will now debug all code, not just user code. Am I doing something wrong? Monodevelop 2.8.6.3 on Ubuntu 2012.04. Nothing special appears on the console with monodevelop -v -v -v. When I press Run instead of Debug, the app crashes immediately saying The application exited with code: 255, but I need Debug to find where the problem is. Note: It is not the same problem as this question, which is about MonoTouch waiting for a phone simulator... the suggestions over there are about the simulator or updating XCode... no simulator nor XCode here.

• wmd editor sanitizing

  - by Ke

  hi, i am trying to find ways to sanitize the input of wmd editor Specifically, I am trying to make HTML tags only available in the <code>tags that wmd generates. Is that possible My problem is that the following code is rendered as html which is vunerable to potential xss attacks e.g. <a onmouseover="alert(1)" href="#">read this!</a> The above code renders normally both in preview mode and when saved to the db. I notice that SO doesnt seem to have this problem. The same code is just rendered as text. I notice that SO has shared their code here http://refactormycode.com/codes/333-sanitize-html Do I really have to use c# in order to sanitize wmd to do this? Any help appreciated , cheers Ke

• linux pthread_suspend

  - by johnnycrash

  Looks like linux doesnt implement pthread_suspend and continue, but I really need em. I have tried cond_wait, but it is too slow. The work being threaded mostly executes in 50us but occasionally executes upwards of 500ms. The problem with cond_wait is two-fold. The mutex locking is taking comparable times to the micro second executions and I don't need locking. Second, I have many worker threads and I don't really want to make N condition variables when they need to be woken up. I know exactly which thread is waiting for which work and could just pthread_continue that thread. A thread knows when there is no more work and can easily pthread_suspend itself. This would use no locking, avoid the stampede, and be faster. Problem is....no pthread_suspend or _continue. Any ideas?

• Nested flowlayout panel not wrapping

  - by SnOrfus

  I've got a FlowLayoutPanel with properties: Dock = Fill (in a usercontrol) FlowDirection = TopDown WrapContents = false I do it this way so that each item added to the panel gets added to the bottom. The items that I add to this panel are usercontrols which themselves have FlowLayoutPanels on them, however they have the standard behaviour (LeftToRight, WrapContents = true). The problem that I'm having is that the interior usercontrol's FlowLayoutPanel isn't resizing to fill the outer control, but when I set autosizing to true on these controls, then the panel won't wrap its contents - which is a known problem apparently. If it helps visualize what I'm trying to do, it looks like this: ______________________________ | __________________________ | Outer box = exterior flowlayout | |Text____________________| | (TopDown, NoWrap) | | # # # # # # # # # # # #| | | | # # # # | | Interior boxes = usercontrols with text and a | |________________________| | flowlayoutpanel on them | __________________________ | (LeftToRight, Wrap) | |Text____________________| | | | # # # # # # # # # # # #| | # = pictures | | # # | | | |________________________| | |____________________________|
