• Modal MessageBox for ASP.NET without jQuery

  - by Joe

  I have an assembly with custom ASP.NET server controls that is used in several, mostly in-house, ASP.NET 2.0 applications. The server controls use simple modal popup messageboxes, which are currently implemented using the javascript alert and confirm functions. I want to release a new version of this assembly that uses a better solution for messageboxes, including support for Yes/No buttons. The appearance would be something like a simplified version of the Ajax Control Toolkit ModalPopup extender (sample here). My constraints are that this should be as easy as possible to integrate into existing ASP.NET 2.0 applications without introducing new dependencies: ideally just drop in a new version of the assembly, that contains all the javascript it needs as an embedded resource, and possibly a CSS file. Because of this constraint, I am not considering solutions I've seen that use jquery, or the ASP.NET Ajax Control Toolkit, which appears to require adding elements to pages that use the extenders (ScriptManagers and the like). Any recommendations?

• Browser Detection and Zend MVC

  - by Vincent

  I have a PHP application using Zend MVC framework. The entry point for every request to the application is in /public/index.php. I have a Browser class that has functions to check if the user's browser is compatible with application or not. My dilemma is, index.php is executed for every controller call. So there are chances that this file gets executed multiple times within the same page and hence redirection becomes an issue. What's the best way to solve the looping issue? Thanks

• Three ways to upload/post/convert iMovie to YouTube

  - by user351686

  For Mac users, iMovie is probably a convenient tool for making, editing their own home movies so as to upload to YouTube for sharing with more people. However, uploading iMovie files to YouTube can't be always a smooth run, I did notice many people complaining about it. This article is delivered for guiding those who are haunted by the nightmare by providing three common ways to upload iMovie files to YouTube. YouTube and iMovie YouTube is the most popular video sharing website for users to upload, share and view videos. It empowers anyone with an Internet connection the ability to upload video clips and share them with friends, family and the world. Users are invited to leave comments, pick favourites, send messages to each other and watch videos sorted into subjects and channels. YouTube accepts videos uploaded in most container formats, including WMV (Windows Media Video), 3GP (Cell Phones), AVI (Windows), MOV (Mac), MP4 (iPod/PSP), FLV (Adobe Flash), MKV (H.264). These include video codecs such as MP4, MPEG and WMV. iMovie is a common video editing software application comes with every Mac for users to edit their own home movies. It imports video footage to the Mac using either the Firewire interface on most MiniDV format digital video cameras, the USB port, or by importing the files from a hard drive where users can edit the video clips, add titles, and add music. Since 1999, eight versions of iMovie have been released by Apple, each with its own functions and characteristic, and each of them deal with videos in a way more or less different. But the most common formats handled with iMovie if specialty discarded as far as to my research are MOV, DV, HDV, MPEG-4. Three ways for successful upload iMovie files to YouTube Solution one and solution two suitable for those who are 100 certainty with their iMovie files which are fully compatible with YouTube. For smooth uploading, you are required to get a YouTube account first. Solution 1: Directly upload iMovie to YouTube Step 1: Launch iMovie, select the project you want to upload in YouTube. Step 2: Go to the file menu, click Share, select Export Movie Step 3: Specify the output file name and directory and then type the video type and video size. Solution 2: Post iMovie to YouTube straightly Step 1: Launch iMovie, choose the project you want to post in YouTube Step 2: From the Share menu, choose YouTube Step 3: In the pop-up YouTube windows, specify the name of your YouTube account, the password, choose the Category and fill in the description and tags of the project. Tick Make this movie more private on the bottom of the window, if possible, to limit those who can view the project. Click Next, and then click Publish. iMovie will automatically export and upload the movie to YouTube. Step 4: Click Tell a Friend to email friends and your family about your film. You are also allowed to copy the URL from Tell a Friend window and paste it into an email you created in your favourite email application if you like. Anyone you send to email to will be able to follow the URL directly to your movie. Note: Videos uploaded to YouTube are limited to ten minutes in length and a file size of 2GB. Solution 3: Upload to iMovie after conversion If neither of the above mentioned method works, there is still a third way to turn to. Sometimes, your iMovie files may not be recognized by YouTube due to the versions of iMovie (settings and functions may varies among versions), video itself (video format difference because of file extension, resolution, video size and length), compatibility (videos that are completely incompatible with YouTube). In this circumstance, the best and reliable method is to convert your iMovie files to YouTube accepted files, iMovie to YouTube converter will be inevitably the ideal choice. iMovie to YouTube converter is an elaborately designed tool for convert iMovie files to YouTube workable WMV, 3GP, AVI, MOV, MP4, FLV, MKV for smooth uploading with hard-to-believe conversion speed and second to none output quality. It can also convert between almost all popular popular file formats like AVI, WMV, MPG, MOV, VOB, DV, MP4, FLV, 3GP, RM, ASF, SWF, MP3, AAC, AC3, AIFF, AMR, WAV, WMA etc so as to put on various portable devices, import to video editing software or play on vast amount video players. iMovie to YouTube converter can also served as an excellent video editing tool to meet your specific program requirements. For example, you can cut your video files to a certain length, or split your video files to smaller ones and select the proper resolution suitable for demands of YouTube by Clip or Settings separately. Crop allows you to cut off unwanted black edges from your videos. Besides, you can also have a good command of the whole process or snapshot your favourite pictures from the preview window. More can be expected if you have a try.

• How to invalidate a single data item in the .net cache in VB

  - by Craig

  I have the following .NET VB code to set and read objects in cache on a per user basis (i.e. a bit like session) '' Public Shared Sub CacheSet(ByVal Key As String, ByVal Value As Object) Dim userID As String = HttpContext.Current.User.Identity.Name HttpContext.Current.Cache(Key & "_" & userID) = Value End Sub Public Shared Function CacheGet(ByVal Key As Object) Dim returnData As Object = Nothing Dim userID As String = HttpContext.Current.User.Identity.Name returnData = HttpContext.Current.Cache(Key & "_" & userID) Return returnData End Function I use these functions to hold user data that I don't want to access the DB for all the time. However, when the data is updated, I want the cached item to be removed so it get created again. How do I make an Item I set disappear or set it to NOTHING or NULL? Craig

• Accessing one process's memory contents from another module

  - by Fangkai Yang

  I am developing a virtual device driver such that the user can write to the driver a process' pid and a virtual address, and the module will use these two values to get the memory contents of the target process. I am wondering if there is any easy functions that can fetch user page's data at this virtual address. I have tried get_user but this is not possible because the modules executing get_user at another process's context. I also tried to use ptrace_readdata, however, it seems that the file at /kernel/ptrace.c leaves a function access_process_vm undefined and also I don't know how to compile the source code of my module with this file (the linker seaches file in /linux/include by default). I am wondering if there are any other solutions...

• Loose coupling of COM in C# or How to avoid COMException 0x80040154

  - by user283318

  I have a .Net 2 C# application I am developing which uses a VB 6 generated COM DLL. The VB DLL is updated frequently any my application crashes with a System.Runtime.InteropServices.COMException (0x80040154). The part of the COM DLL I use does not change but the version (and CLSID) will. The "Specific Version" option for the reference is false. The WrapperTool is tlbimp. How do I tell my application not to worry about changes in the DLL? Is there any way of checking just the functions I am using?

• Is recursion ever faster than looping?

  - by Carson Myers

  I know that recursion is sometimes a lot cleaner than looping, and I'm not asking anything about when I should use recursion over iteration, I know there are lots of questions about that already. What I'm asking is, is recursion ever faster than a loop? To me it seems like, you would always be able to refine a loop and get it to perform more quickly than a recursive function because the loop is absent constantly setting up new stack frames. I'm specifically looking for whether recursion is faster in applications where recursion is the right way to handle the data, such as in some sorting functions, in binary trees, etc.

• lwjgl applets 101: How can I write them?

  - by Vuntic

  I have a working app in lwjgl. It doesn't do much yet; I've just started, but it does compile and run like it's supposed to. I want to make it into an applet. I've followed the guide here, and I have an applet that runs nicely and displays text and such in the applet area and can access the functions of lwjgl (like Sys.alert), but I can't figure out how to get opengl to actually render. I've tried extending an AWTGLCanvas and calling this.add(myAWTGLCanvas), where this is the Applet that I'm using, but... nothing. The initGL() and paintGL() methods never get called. I wonder if I'm supposed to be doing something with Display, but that's not for applets, right? Help? Also: This counts as a "beginner" question, right?

• Getting Types in Win32 Dll

  - by Usman

  Hello, I want to know the types and details in a plain Win32DLL just like we can get in case of COM.In COM every thing embed inside idl and results in TLB, here we get every thing , MSFT exposes APIS by which we can extract types. In case of Win32 I strongly needed types defined in it and all details of that type(e.g what are members in it and their types as well). Parsing PE file and looking up export table only gives the exported functions. I want all custom types(Win32 interfaces,classes and members details with types) defined in it. How? Regards Usman

• Ext JS how to tell PagingToolbar to use parent Grid storage?

  - by Nazariy

  I'm trying to build application that use single config passed by server as non native JSON (can contain functions). Everything works fine so far but I'm curious why PagingToolbar does not have an option to use parent Grid store? I have tried to set store in my config like this, but without success: {... store:Ext.StoreMgr.lookup('unique_store_id') } Is there any way to do so without writing tons of javascript for each view defining store, grid and other items in my application or at least extend functionality of PaginationToolbar that use options from parent object? UPDATED, Here is short example of server response (minified) { "xtype":"viewport", "layout":"border", "renderTo":Ext.getBody(), "autoShow":true, "id":"mainFrame", "defaults":{"split":true,"useSplitTips":true}, "items":[ {"region":"center", "xtype":"panel", "layout":"fit", "id":"content-area", "items":{ "id":"manager-panel", "region":"center", "xtype":"tabpanel", "activeItem":0, "items":[ { "xtype":"grid", "id":"domain-grid", "title":"Manage Domains", "store":{ "xtype":"arraystore", "id":"domain-store", "fields":[...], "autoLoad":{"params":{"controller":"domain","view":"store"}}, "url":"index.php" }, "tbar":[...], "bbar":{ "xtype":"paging", "id":"domain-paging-toolbar", "store":Ext.StoreMgr.lookup('domain-store') }, "columns":[...], "selModel":new Ext.grid.RowSelectionModel({singleSelect:true}), "stripeRows":true, "height":350, "loadMask":true, "listeners":{ "cellclick":activateDisabledButtons } } ] }, } ] }

• Updating multiple Sprites - AS3 performance best practices

  - by dani

  Within the container "BubbleContainer" I have multiple "Bubble sprites". Each bubble's graphics object (a circle) is updated on a timer event. Let's say I have 50 Bubble sprites and each circle's radius should be updated with a mathematical formula. How do I organize this logic? How do I update all Bubble sprites within the BubbleContainer? (should I call a bubble.update() function or make a temporary reference to the graphics object?) Where do I put the Math logic? (as static functions?)

• SHELL OR PERL QUESTION

  - by user150674

  I have a very large file, named 'ColCheckMe', tab-delimited, that you are asked to process. You are told that each line in 'ColCheckMe' has 7 columns, and that the values in the 5th column are integers. Using shell functions indicate how you would verify that these conditions were satisfied in 'ColCheckMe' K got this... nawk ‘ NF != 7 { Printf(“[%d] has invalid [%d] number of fileds\n”, FNR, NF) } $5 !~ /^[0-9]+$/ { Printf(“[%d] 5th field is invalid [%s]\n”, FNR, $5) }’ ColCheckMe Now, 2. In with the similar file, you are told that each value in column 1 is unique. How would I verify that? Also write a shell function that counts the number of occurrences of the word “SpecStr” in the file 'ColCheckMe' Any one can help in SHELL or everything including the first in PERL Scripting.

• Find Window At Location Using Carbon And Carbon Problems In 64-Bit Applications

  - by JxXx

  As I said in some questions today I´m looking for the way to get window or windowPart references at a certain location. Although I know I could use Cocoa for this purpose (I don´t know how to do it yet) I prefer (and probably need) to do this using Carbon because the entire application that needs this functionality is written in C++ but I´ve found many problems trying it. Does anyone get a valid windowPtr or windowRef using one of the following functions? FindWindow, MacFindWindow, HIWindowFindAtLocation or FindWindowOfClass I always get 0 as the windowRef or windowPtr that I´m looking for. What I´m doing wrong? Any ideas? It´s true that now if you want to create a 64-bit application for Mac OS X, you need to use Cocoa to implement its user interface because some APIs commonly used by Carbon applications are not available in 64-bit applications? Thank you. JxXx

• Differences between AForge and OpenCV

  - by vrish88

  Hello, I am just learning about computer vision and C#. It seems like two prominent image processing libraries are OpenCV and AForge. What are some of the differences of the two? I am making a basic image editor in C# and while researching I have come across articles on both. But I don't really know why I would choose one over the other. I would like to eventually improve the app to include more advanced functions. Thanks.

• Why does this call to jQuery's $.ajax() fire an empty request in Chrome and Firefox?

  - by Martin Wiboe

  Hello, I am trying to call a WCF RESTful service from jQuery. I am using JSON to encode both request and response. The following code functions correctly in IE8: url = 'http://ipv4.fiddler:5683/WeatherWCF/NewBinding/MyService/GetValueFloat'; $.ajax({ url: url, data: '{"alias": "Udetemperatur"}', type: "POST", contentType: "application/json; charset=utf-8", dataType: "text", // not "json" we'll parse success: function(res) { alert('Received response: ' + res); } }); However, in both Firefox and Chrome, res contains an empty string. After using Fiddler to monitor the request, it appears that jQuery sends an empty request to the server as shown in this screen dump: http://imgur.com/EJgwS.png This is the successful request: http://imgur.com/S77BA.png What am I doing wrong?

• "Randomly" occurring errors...

  - by ClarkeyBoy

  Hi, My website has a setup whereby when the application starts a module called SiteContent is "created". This runs a clearup function which basically deletes any irrelevant data from the database, in case any has been left in there from previously run functions. The module has instances of Manager classes - namely RangeManager, CollectionManager, DesignManager. There are others but I will just use these as an example. Each Manager class contains an array of items - items may be of type Range, Collection or Design, whichever one is relevant. Data for each range is then read into an instance of Range, Collection or Design. I know this is basically duplicating data - not very efficient but its my final year project at the moment so I can always change it to use Linq or something similar later, when I am not pressured by the one month deadline. I have a form which, on clicking the Save button, saves data by calling SiteContent.RangeManager.Create(vars) or SiteContent.RangeManager.Update(Range As Range, vars) (or the equivalent for other manager classes, whichever one happens to be relevant). These functions call a stored procedure to insert or update in the relevant table. Classes Range, Collection and Design all have attributes such as Name, Description, Display and several others. When the Create or Update function is called, the Manager loops through all the other items to check if an item with the same name already exists. The Update function ensures that it does not compare the item being updated to itself. A custom exception (ItemAlreadyExistsException) is thrown if another item with the same name is found. For some weird reason, if I go into a Range, Collection or Design in edit mode, change something and try to update it, it occasionally doesnt update the item. When I say occasionally I mean every 3 - 4 page loads, sometimes more. I see absolutely no pattern in when or why it occurs. I have a try-catch statement which catches ItemAlreadyExistsException, and outputs "An item with this name already exists" when caught. Occasionally it will output this; other times it will not. Does anyone have any idea why this could happen? Maybe a mistake which someone has made and solved before? I used to have regular expressions in place that the names were compared to - I believe it was [a-zA-Z]{1, 100} (between 1 and 100 lower- or upper-case characters). For some reason the customer who I am developing the site for used to get errors saying its not in the correct format. Yet he could try the same text 5 minutes later and it would work fine. I am thinking this could well be the same problem, since both problems occur at random. Many thanks in advance. Regards, Richard Clarke Edit: After much time spent narrowing down the code, I have decided to wait till my brother, who has been a programmer for at least 8 years more than I have, to come down over Easter and get him to have a look at it. If he cant solve it then I will zip the files up and put them somewhere for people to access and have a go at. I narrowed it down literally to the minimum number of files possible, and it still occurs. It seems to be about every 10th time. Having said that, I force the manager classes to refresh every 10 page loads or 5 minutes (whichever one is sooner). I may look into this - this could be causing a problem. Basically each Manager contains an array of an object. This array is populated using data from the database. The Update function takes an instance of the item and the new values to be set for the object. If it happens to be a page load where the array is reset (ie the data is loaded freshly from the database) then the object instance with the same ID wont be the same instance as the one being passed in. This explains the fact that it throws an ItemAlreadyExistsException now and then. It all makes sense now the more I think about it. If I were to pass in the ID of the object to be altered, rather than the object itself, then it should work perfectly. I will answer the question if I solve it..

• Transpose a file in bash

  - by Thrawn

  Hi all, I have a huge tab-separated file formatted like this X column1 column2 column3 row1 0 1 2 row2 3 4 5 row3 6 7 8 row4 9 10 11 I would like to transpose it in an efficient way using only using commands (I could write a ten or so lines Perl script to do that, but it should be slower to execute than the native bash functions). So the output should look like X row1 row2 row3 row4 column1 0 3 6 9 column2 1 4 7 10 column3 2 5 8 11 I thought of a solution like this cols=`head -n 1 input | wc -w` for (( i=1; i <= $cols; i++)) do cut -f $i input | tr $'\n' $'\t' | sed -e "s/\t$/\n/g" >> output done But it's slow and doesn't seem the most efficient solution. I've seen a solution for vi in this post, but it's still over-slow. Any thoughts/suggestions/brilliant ideas? :-)

Loking at the examples I see that dates tend to be saved in dimension tabels. But I think, that it makes no sense for time. The dimension table would grow and grow. On the other hand JOIN with date dimension table is more efficent than using date/time functions in SQL. What are your opinions/solutions ? (I'm using Infobright)

• reporting services: use a custom assembly with a local (RDLC) report

  - by JMarsch

  Hello: I am designing a report that will be used in local mode (an RDLC file) in a Winform app. I have a custom assembly with a static class that has some functions that I want to use inside of the report (as expressions). I have found all sorts of help for doing this with RDL reports, but I'm running into a permissions problem with my RDLC report. I get the following error at runtime: "The report references the code module (my module), which is not a trusted assembly". I know that this is some kind of a code security issue, but I'm not sure what to do to fix it. The documentation that I have seen online is aimed at RDL reports, and it instructs me to edit a SQL Server-specific policy file. I'm using RDLC, so there is no sql server involved. What do I need to do to acquire the appropriate permissions?

• Visual C#, Large Arrays, and LOH Fragmentation. What is the accepted convention?

  - by Gorchestopher H

  I have an other active question HERE regarding some hopeless memory issues that possibly involve LOH Fragmentation among possibly other unknowns. What my question now is, what is the accepted way of doing things? If my app needs to be done in Visual C#, and needs to deal with large arrays to the tune of int[4000000], how can I not be doomed by the garbage collector's refusal to deal with the LOH? It would seem that I am forced to make any large arrays global, and never use the word "new" around any of them. So, I'm left with ungraceful global arrays with "maxindex" variables instead of neatly sized arrays that get passed around by functions. I've always been told that this was bad practice. What alternative is there? Is there some kind of function to the tune of System.GC.CollectLOH("Seriously") ? Are there possibly some way to outsource garbage collection to something other than System.GC? Anyway, what are the generally accepted rules for dealing with large (85Kb) variables?

• Programming pattern to flatten deeply nested ajax callbacks?

  - by chiborg

  I've inherited JavaScript code where the success callback of an Ajax handler initiates another Ajax call where the success callback may or may not initiate another Ajax call. This leads to deeply nested anonymous functions. Maybe there is a clever programming pattern that avoids the deep-nesting and is more DRY. jQuery.extend(Application.Model.prototype, { process: function() { jQuery.ajax({ url:myurl1, dataType:'json', success:function(data) { // process data, then send it back jQuery.ajax({ url:myurl2, dataType:'json', success:function(data) { if(!data.ok) { jQuery.ajax({ url:myurl2, dataType:'json', success:mycallback }); } else { mycallback(data); } } }); } }); } });
