• Visual Studio 2010 RC + ASP.NET MVC 2 RTM won't re-target from .NET Framework 4 to 3.5

  - by Solution Evangelist

  Per the above I am trying to re-target a fresh ASP.NET MVC 2 application in Visual Studio 2010 RTM. After all sorts of tweaking the closest I am getting is the error below: The primary reference "System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the framework assembly "System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which could not be resolved in the currently targeted framework. ".NETFramework,Version=v3.5". To resolve this problem, either remove the reference "System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL" or retarget your application to a framework version which contains "System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a". Is there anyone who can assist in having this re-targeted to .NET Framework 3.5 (SP1), or is there perhaps a zip file of a VS 2010 + .NET Framework v3.5 + ASP.NET MVC 2 RTM project already online I could grab?

• Work-around for PHP5's PDO rowCount MySQL issue

  - by Steven Surowiec

  I've recently started work on a new project using PHP5 and want to use their PDO classes for it. The problem is that the MySQL PDO Driver doesn't support rowCount() so there's no way to run a query and then get the number of affected rows, or rows returned, which is a pretty big issue as far as I'm concerned. I was wondering if anyone else has dealt with this before and what you've done to work around it. Having to do a fetch() or fetchAll() to check if any rows were affected or returned seems like a hack to me, I'd rather just do $stmt-numRows() or something similar.

• How can I find which process has opened a specific file?

  - by Hosam Aly

  How can I find which processes have a specific file opened, and their open, access and share modes? Additionally, is it possible to change these values for a process? Or is it even possible to open a file for reading if it is already opened for exclusive access by another process? Please note that I don't want to invalidate the handle of the process having the file opened. I just want to be able to access the file (if possible). (I'm mainly asking about Windows, but solutions for other platforms are welcome, since they contribute to the community's knowledge.) Edit: I found some answers for my first question here and there. Edit 2: Thanks everybody for the tools you mentioned, but I am mainly looking for programmatical techniques (e.g. using Win32 APIs).

• Is there a Novatel Wireless Modem Emulator or something similar?

  - by David Brown

  Novatel Wireless provides their NovaCore SDK for developers wishing to interface with their line of modems. I'm currently developing an open source managed wrapper for it, but I'm having difficulties with testing. I own a Novatel MiFi and have mobile broadband service through Sprint, but that can only get me so far. The device is already activated, thus I can't test the network activation features of the NovaCore SDK. There are also certain features only available for HSPA modems, which I am not able to get in my area. Is there an emulator capable of emulating a Novatel Wireless modem so that I can test my library without physical hardware and an actual data connection? If not, do you have any other suggestions that might help in this situation? I've contacted Novatel Wireless via email and their developer forum, but have not received a response. Thanks!

• iBatis mapping: map a string field into a List<String>

  - by Roberto

  Hi all, is it possible to map a string field with a particular format like: aaa,bbb,ccc,ddd into a List having elements [aaa, bbb, ccc, ddd] using iBatis? What I need is to have in my model something like: public class Request{ private List<String> fieldOne; public List<String> getFieldOne(){....} public void setFieldOne(){....} } even if in my table the field is a simple string. Is this possible? Thanks Roberto

• Debugging feature activation in SharePoint 2007

  - by Eric U.

  I have a SharePoint feature that is activated under 'Site Collection Features' that is having some issues being activated. I've activated it through the stsadm as well as the SharePoint UI, both unsuccessful. The feature toggles from deactivated to activated, but the result that should be there is not. The result is some pages that should be created. So my question is does anyone know of a way to step through the activation of features process? I'd like to be able to attach Visual Studio 2008 to the browser and step through a few breakpoints that I've set. I've narrowed the error down to the FeatureReceiver's FeatureActivated(SPFeatureReceivrProperties properties) Pages that I've been referencing: http://msdn.microsoft.com/en-us/library/ee231550.aspx http://blogs.msdn.com/b/sharepoint/archive/2007/04/10/debugger-feature-for-sharepoint.aspx

• Why is there no code-folding in emacs ?

  - by Pierre

  There are several questions on SO about how to get code folding in emacs, without having to add any special characters like "markers" in the comments for example. Someone said that there was "no perfect solution." It seems that it could be done by parsing the source of the program being written and look for matching parenthesis or bracket, or to do it based on indentation. You could also use a combination of scripts that use different methods. So why is it commonly accepted that there is no "perfect" and straightforward way to get code-folding in emac? Is there something in emacs or its architecture that makes it hard to program? If it were easy, after so many years of smart people using emacs you would think that someone would have wrote it.

• C# to Java: where T : new() Syntax

  - by Shiftbit

  I am porting some C# code over to Java. I am having trouble with the where Syntax, specifically new(). I understand that where is similar to Java's generic: T extends FOO. How I can replicate the new() argument in Java? "The new() Constraint lets the compiler know that any type argument supplied must have an accessible parameterless--or default-- constructor." - MSDN ie: public class BAR<T> : BAR where T : FOO, new() Right now I have: public class BAR<T extends FOO> extends ABSTRACTBAR { public HXIT(T t){ this.value = t; } .... }

• Validation of user input or ?????????

  - by zaf

  We're letting users search a database from a single text input and I'm having difficulties in filtering some user supplied strings. For example, if the user submits: ????????? lcd SONY (Note the ?'s) I need to cancel the search. I include the base64 encoded version of the above string wrapped up so that its easy run: print(base64_decode("1MfLxc/RwdPHIGxjZCBTT05Z")); I've ignored such inputs before but now (am not sure why) just realised the mysql database query is taking nearly forever to execute so this is now on high priority. Another example to highlight that we are using utf-8 and mb_detect_encoding is not helping much: print(base64_decode("zqDOm8+Fzr3PhM63z4HOuc6/IM+Bzr/Phc+HzyU=")); ????t???? ?????% So: how can I detect/filter these inputs? how is this input being generated?

• Javascript: variable in outer function not changed by inner function

  - by Weng-Lock Mok

  I am having a small issue with what I believe is probably my misunderstanding of Javascript closures. I have this piece of code -- getStdOpts: function(tbl, filt) { var vals = new Array(); this.srvs.getStdOptions( { tbl: tbl }, { 'ok': function(rsp) { for (var i in rsp) { vals.push({ value: rsp[i].id, text: rsp[i].descr }); } } } ); return vals; } In essence, although the inner function inside the getStdOptions call ('ok': function...) pushes new values into the vals array, when accessed from outside the call, the vals array is empty. When accessed from within the inner function, vals contains all the elements as expected. Would really appreciate any help I can get on this matter.

• Data validate tools (ETL tools) for SQL server

  - by Stan

  I have some data in Excel and need to import into database. Is there any tool that can validate and maybe clean the data? Does Red Gate have such tool? The input will be Excel. Given table constraints, eg. CHECK, UNIQUE KEY, datetime format, NOT NULL. Desire output should be as least shows which lines are having problems, and then fix some trivial error automatically, like fill in default value for NULL columns, automatically correct datetime format. I know using Python can build such a script. But just wonder what's the popular way to do this. Thanks.

• .aspx character coding

  - by kwek-kwek

  I am having an problem. First time working with a windows server, do you know if there is any problem in character coding? My document is set to content="text/html; charset=UTF-8" but it's giving me funny words... you can check it here. This site is a pure HTML with few includes but anything else is just HTML. I can convert them to HTML entities but that is basically wasting my time. I never had this problem with any website I did except for this. Some others said "The problems seems to be that you have converted the text into utf-8 twice.". But how would Coverted it twice since dreamweaver should convert it for me but in this case it doesn't.

• Using TSQLUnit to test INSTEAD OF triggers

  - by Jeff Jones

  I have an INSTEAD OF trigger on a table in my SQL Server 2005 database that checks several incoming values. If an incoming value is invalid, an error is raised and the transaction is rolled back. Otherwise the record is inserted. I would like to include a TSQLUnit test of this trigger where, if an invalid value is inserted, having the transaction rolled back is the successful outcome of the test. I have created a test procedure to do this, but rolling back the transaction aborts execution of the whole suite of tests. Has anyone had success with this? If so, how did you accomplish it? If this is not possible with TSQLUnit, how do you test your triggers? Or do you test them at all?

• How to jQuery slidedown once page has already been loaded

  - by bulltorious

  I am having a timing issue when attempting to slide down my more info div. My desired functionality is that the div slidesdown from the top once the page has already been rendered. My problem is if I use $(document).ready().. the animation does not visibly occur. Here is my code: $(document).ready(function() { $(".MoreInfo").slideDown('slow'); }); If I strap it to some other element's click for example, it works beautifully. But I am not sure how to make it visibly slide down once the page has loaded. Thanks!

• Easiest way to retrofit retry logic on LINQ to SQL migration to SQL Azure

  - by Pat James

  I have a couple of existing ASP .NET web forms and MVC applications that currently use LINQ to SQL with a SQL Server 2008 Express database on a Windows VPS: one VPS for both IIS and SQL. I am starting to outgrow the VPS's ability to effectively host both SQL and IIS and am getting ready to split them up. I am considering migrating the database to SQL Azure and keeping IIS on the VPS. After doing initial research it sounds like implementing retry logic in the data access layer is a must-do when adopting SQL Azure. I suspect this is even more critical to implement in my situation where IIS will be on a VPS outside of the Azure infrastructure. I am looking for pointers on how to do this with the least effort and impact on my existing code base. Is there a good retry pattern that can be applied once at the LINQ to SQL data access layer, as opposed to having to wrap all of my LINQ to SQL operations in try/catch/wait/retry logic?

• Evenly select N elems from array

  - by ninuhadida

  Hi, I need to evenly select n elements from an array. I guess the best way to explain is by example. say I have: array [0,1,2,3,4] and I need to select 3 numbers.. 0,3,4. of course, if the array length <= n, I just need to return the whole array. I'm pretty sure there's a defined algorithm for this, been trying to search, and I took a look at Introduction to algorithms but couldn't find anything that met my needs (probably overlooked it) The problem I'm having is that I can't figure out a way to scale this up to any array [ p..q ], selecting N evenly elements. note: I can't just select the even elements from the example above.. A couple other examples; array[0,1,2,3,4,5,6], 3 elements ; I need to get 0,3,6 array[0,1,2,3,4,5], 3 elements ; I need to get 0, either 2 or 3, and 5

• AJAX ModalPopup Pops Behind (Under) Page Content (Negative z-index)

  - by Aaron Hoffman

  I am having an issue with the AJAX ModalPopupExtender in version 40412 of the AJAX Control Toolkit (http://ajaxcontroltoolkit.codeplex.com/releases/view/43475). The first time the ModalPopup is made visible it works correctly. The z-index is set to 6001 (and the background Div's z-index is set to 6000) and the Popup appears above everything else. If the cancel button within the ModalPopup is clicked, it also has the correct functionality, the display is set to "none" and the ModalPopup is no longer visible. However, when the Popup is triggered again, the z-index is only set to 2000 which is still visible above everything else, but if it is canceled and triggered again it is set to -2000 which is not visible (the z-index is decreasing by 4000 each time). I'm not sure why this is happening. Any ideas how to fix it? Special circumstances: There are multiple ModalPopup's on the page. All ModalPopups are triggered in code-behind through partial-page postbacks (using the .Show() method) ModalPopupExtenders are within the same UpdatePanels that are displayed as popups

• IMAP + TLS/SSL with synapse ?

  - by azera

  i'm currently trying to add to a software the capability to list unread emails in the user's inbox using imap. After having no success at all using indy10, I discovered synapse which seemed better for what I needed, but I can't find a way to get it working. My problem is with the login (thus I think with the ssl configuration), I can't find a working combination of "FullSSL", "Sock.SSL.SSLType" and "AutoTLS", whetever I do the "Login()" function fails. For the sake of testing, is any of you able to connect to gmail's imap server using synapse, and if yes how ?

• Remove a keyboard shortcut binding in Visual Studio using Macros

  - by Pete

  Hi. I have a lot of custom keyboard shortcuts set up. To avoid having to set them up every time I install a new visual studio (happens quite a lot currectly, with VS2010 being in beta/RC) I have created a macro, that sets up all my custom commands, like this: DTE.Commands.Item("ReSharper.ReSharper_UnitTest_RunSolution").Bindings = "Global::Ctrl+T, Ctrl+A" My main problem is that Ctrl+T is set up to map to the transpose char command by default. So I want to remove that default value in my macro. I have tried the following two lines, but both throw an exception DTE.Commands.Item("Edit.CharTranspose").Bindings = "" DTE.Commands.Item("Edit.CharTranspose").Bindings = Nothing Although they kind of work, because they actually remove the binding ;) But I would prefer the solution that doesn't throw an exception. How is that done?

• Parsing JPEG file format: Format of entropy-coded segment (ECS) segments?

  - by me2

  I'm having difficulty understanding the ITU-T T.81 spec for the JPEG file format. Hopefully someone else here has tried to parse JPEG files and/or knows about the details of this file format. The spec indiates that the ECS0 segment starts after the SOS segment but I can't find where in the spec it actually talks about the format of the ECS0 segment or how do detect its start. Simple JPEG implementations online are of limited help because they assume many things about the JPEGs they parse. Can anyone point me in the right direction?

• HTML CSS two columns

  - by Marki

  If my HTML says something along the following <div class="container"> <div class="element"> </div> <div class="element"> </div> [...] <div class="element"> </div> </div> is it then possible to align those elements as if they were in a two-column table? I.e. with 7 elements there would be 4 rows, with the last row only having one element. (The elements themselves have NO special classes or ids like right,left,etc.)

• Flex 4 - Using .pfm/.pfb fonts

  - by Zed-K

  Hi everyone, I just switched to Flash Builder 4 & Flex 4 SDK, and it seems it's no longer possible to use a .pfm/.pfb font, either by embedding it or using it as a system font. I keep getting error messages, and Google can't find anybody having the same issue. I tried several methods: - copy/pasting the [Embed] statement which was working using Flex 3 SDK - installing the font and then try to simply call it by its name in a CSS declaration without embedding it ; seems to work for every .ttf and .otf system fonts, but not for .pfm/.pfm ones - using a Flash-generated swf which embeds the font So far none of these seems to work. Has anybody got an idea on how to achieve this? I actually don't care using a system font without embedding it as long as it works. I'll be really grateful if somebody could help me on this, I'm totally stuck and cannot use another font instead.

• Python Vector Class

  - by sfjedi

  I'm coming from a C# background where this stuff is super easy—trying to translate into Python for Maya. There's gotta' be a better way to do this. Basically, I'm looking to create a Vector class that will simply have x, y and z coordinates, but it would be ideal if this class returned a tuple with all 3 coordinates and if you could edit the values of this tuple through x, y and z properties, somehow. This is what I have so far, but there must be a better way to do this than using an exec statement, right? I hate using exec statements. class Vector(object): '''Creates a Maya vector/triple, having x, y and z coordinates as float values''' def __init__(self, x=0, y=0, z=0): self.x, self.y, self.z = x, y, z def attrsetter(attr): def set_float(self, value): setattr(self, attr, float(value)) return set_float for xyz in 'xyz': exec("%s = property(fget=attrgetter('_%s'), fset=attrsetter('_%s'))" % (xyz, xyz, xyz))
