• Eclipse c++ with mingw comiler cant build boost regex example, can find .a library files

  - by Kim

  Hi, I'm trying to build the boost regex example in eclipse using mingw on vista. I built boost ok with mingw as there are library files XXXX.a. I could build/compile the first boost example that doesnt require any of the compiled boost libraries. When I compile the regex example I get a linker error saying it cant find the library file. I have tried various libray file names eg leave off the .a extension, leave off the lib prefix etc. Now the interesting thing is that if I leave off the library extension and rename the library file to XXX.lib it works and runs ok. So why cant it read the .a library file? It must be my setup somewhere but I dont know where or what to set. From what I read everyone is ok linking the .a file except me :( Thanks in advance, Kim

• SSIS - Wizard vs manual vs programming

  - by alchemical

  I'd like to move 26 tables from one DB to another. I see I can do this in the SSIS Import and Export Wizard. I believe the other approach would be to select tools from the toolbar in Data Flow and then configure them all. When is it better to use the wizard and when is it best to create the package manually (with the visual tools) or programmatically? One thing I noticed with the Wizard is that it lets me select multiple tables at once, but I could not find a way to get back to that screen once the package is created, so that I could edit the various tables all in one place.

• UiElement from abstract class

  - by plotnick

  I placed a control into a grid. let's say the control is derived from public class 'ButBase' which is derived in its turn from System.Windows.Controls.Button. The code normally compiles and app works just fine. But there's something really annoying. When you try to switch to xaml-design tab it will say 'The document root element is not supported by the visual designer', which is normal and I'm totally okay with that, but the thing is, that all the xaml code is underlined and VS2010 says: 'Cannot create an instance of ButBase' although still normally compiles and able to run. I've tried the same code in VS2008, it said that needs to see a public parameterless constructor in the ButBase, and even after I put one it showed the same error. What do I miss here?

• Java Concurrency: CAS vs Locking

  - by Hugo Walker

  Im currently reading the Book Java Concurrency in Practice. In the Chapter 15 they are speaking about the Nonblocking algorithms and the compare-and-swap (CAS) Method. It is written that the CAS perform much better than the Locking Methods. I want to ask the people which already worked with both of this concepts and would like to hear when you are preferring which of these concept? Is it really so much faster? Personally for me the usage of Locks is much clearer and easier to understand and maybe even better to maintain. (Please correct me if I am wrong). Should we really focus creating our concurrent code related on CAS than Locks to get a better performance boost or is sustainability a higher thing? I know there is maybe not a strict rule, when to use what. But I just would like to hear some opinions, experiences with the new concept of CAS.

• How do I get the intellisense in FoxPro 8 to work with .net COM objects?

  - by IsaacB

  Hi, I'm at my wit's end with this. What I'm doing is making a C# dll file that needs to have some methods exposed to FoxPro 8. This guy here http://www.west-wind.com/presentations/VfpDotNetInterop/DotNetFromVFP.asp says that you can put [ClassInterface(ClassInterfaceType.AutoDual)] in front of the (C# in my case) class, and then intellisense in Foxpro magically works. I'm accessing the COM object fine in FoxPro, but unfortunately the intellisense doesn't work, and it's annoying me. Is there some other step I'm missing to this? Is there some registry entry to look for to confirm that the methods are exposed properly (for intellisense to work)? Are there other steps in Foxpro that I'm supposed to follow (I don't know a thing about FoxPro!) It might be a pretty obscure question these days, but someone on here must know the answer! Thanks

• ASP.NET MVC Response Filter + OutputCache Attribute

  - by Shane Andrade

  I'm not sure if this is an ASP.NET MVC specific thing or ASP.NET in general but here's what's happening. I have an action filter that removes whitespace by the use of a response filter: public class StripWhitespaceAttribute : ActionFilterAttribute { public StripWhitespaceAttribute () { } public override void OnResultExecuted(ResultExecutedContext filterContext) { base.OnResultExecuted(filterContext); filterContext.HttpContext.Response.Filter = new WhitespaceFilter(filterContext.HttpContext.Response.Filter); } } When used in conjunction with the OutputCache attribute, my calls to Response.WriteSubstitution for "donut hole caching" do not work. The first and second time the page loads the callback passed to WriteSubstitution get called, after that they are not called anymore until the output cache expires. I've noticed this with not just this particular filter but any filter used on Response.Filter... am I missing something? I also forgot to mention I've tried this without the use of an MVC action filter attribute by attaching to the PostReleaseRequestState event in the global.asax and setting the Response.Filter value there... but still no luck.

• PresentModalViewController problem.

  - by james.ingham

  I have a new view controller on the iPhone which I call using the following line of code: [self presentModalViewController:controller animated:NO]; This works great if animation is on, but I am looking to have an instant switch. The problem is when I set animation to NO, the whole view shifts 20px to the right (it is always in landscape mode) as if there is a status bar but in portrait mode!? In this example the yellow space is the new view controller. I've tried this in a new project and the same thing happens. It may be a bug but does anyone have a fix? Thanks

• Installing Loadrunner

  - by grouchomarx

  Well, it figures that Loadrunner is not easy to install. Apprently, we need: ? .NET Framework 3.5 ? Microsoft Data Access Components (MDAC) 2.8 SP1 (or later) ? Microsoft Windows Installer 3.1 ? Microsoft Core XML Services (MSXML) 6.0 ? Microsoft Visual C++ 2005 Redistributable Package (x86) ? Microsoft Visual C++ 2008 Redistributable Package (x86) ? Web Services Enhancements (WSE) 2.0 SP3 for Microsoft .NET Redistributable Runtime MSI ? Web Services Enhancements (WSE) 3.0 for Microsoft .NET Redistributable Runtime MSI Once done, I'm still trying to figure out how to execute this thing. Has anyone gone through the same experience with it ?

• ASPX has image from portal.mxlogic.com

  - by codie

  I have a aspx page I'm trying to (remotely) debug. It should add an image and set the src. The value seems correct if i msgbox the value that should be used for the "ImageUrl" But viewing the page there is no image and the src is: http://portal.mxlogic.com/images/transparent.gif This is a mcaffee page so is this some security thing...that is just a wild\crazy guess. Maybe i'm missing something very obvious...I did not write the code and I'm not really a aspx developer. Any ideas?? llf as requested some code... TableCell tc = new TableCell(); {code to create imgurl ... very specific to this situation} MessageBox(imgurl); //The imgurl value here is correct if (imgurl != null) { image.ImageUrl = imgurl; } else { MessageBox("image url is null"); } tc.Controls.Add(image); tr.Cells.Add(tc); Table1.Rows.Add(tr)

• How to apply text shadow to UITextView?

  - by mystify

  Actually I love UILabel. They're sweet. Now I had to go to UITextView because UILabel is not aligning text vertically to the top. Damn. One thing I really need is a text shadow. UILabel has it. UITextView seems to not have it. But I guess that guy just uses the same underlying UIKit NSString additions?? Maybe someone already has a solution for that problem? What would I overwrite?

• Google Chrome Speed Tracer what does Request Timing and Response Timing actually measure?

  - by Bryce Thomas

  I'm testing out the Google Chrome Speed Tracer on a few common web pages and taking a look through the results. One thing I'm not sure I understand is what the "Request Timing" and "Response Timing" properties of resources are actually measuring. Initially I thought Request Timing must measure the time from a request for a resource being sent and when that request arrived at the server. However, I then wondered how the Speed Tracer would actually have any way of measuring this. Furthermore, the Response Timing that I'm getting for resources tends to be far less than the Request Timing (e.g. 500ms request, 1ms response), which is a little bit suss. So is anyone able to explain exactly what Request Timing and Response Timing are measuring?

• EMBED vs. OBJECT

  - by JayhawksFan93

  Which is the right/best tag to use in my HTML file when I want to display the Adobe PDF viewer? Right now I'm using the code below, but there are weird side effects (e.g. it seems to steal the starting focus that I've set to another INPUT text box; it doesn't seem to play real well with the jQueryUI Resizeable class; etc.) <embed src="abc.pdf" type="application/pdf" /> Could I even do the same thing with the OBJECT tag? Are there advantages/disadvantages to using one tag vs. the other?

• Algorithm and data structure learning resources for dynamic programming

  - by Pranav

  Im learning dynamic programming now, and while I know the theory well, designing DP algorithms for new problems is still difficult. This is what i would really like now- A book or a website, which poses a problem which can be solved by dynamic programming. Also there is the solution with an explanation available, which i would like to see if i cant solve the problem even after butting my head at it for a few hours. Is there some resource that provides this sort of a thing for several categories of algorithms- like graph algorithms, dynamic programming, etc? P.S. I considered Topcoder, but the solutions there are not really appropriate for learning to implement efficient solutions.

• Microsoft Entrourage: rendering hyperlinks?

  - by rehanift

  When we send emails from my project, we send in both text/plain and text/html formats. All major clients (gmail, yahoo, hotmail, thunderbird, outlook) correctly display the simple HTML that we are using. However, Entourage renders all tags EXCEPT hyperlinks. What is confusing is that emails from other domains render hyperlinks correctly in Entourage. We have tried comparing the source / headers of our emails with others emails that seem to "work" and don't see any obvious differences. I googled around this issue and the only thing I could find what that Entourage doesn't allow users to insert hyperlinks when composing a message. Does anyone know what I might be doing wrong?

• What way to use the CGContext to draw is suitable?

  - by Tattat

  I know that the CGContext cannot call it to draw directly, and it needs to fill the drawing logic in the drawInContext, and call the CGContext to draw using "setNeedsDisplay", so, I designed a cmd to execute, but it cause some problems... like this : http://stackoverflow.com/questions/2617827/why-i-cant-draw-in-a-loop-using-uiview-in-iphone I think the CGContext is very different from my previous programming experience....(I used HTML5 canvas, that allow me add more details, after I draw, so do the Java Swing) Actually, I want to know what is the suitable to implement these kind of thing in Apples' programmer mind. Thz.

• VS 2010 very slow

  - by kaze

  I have just upgraded to VS 2010, and I have performance problems which I did not have before (in VS 2008). The most annoying thing is that it freezes while I work in the text editor. Sometimes when it freezes I see that it is saving auto recovery information, but not always. Almost anything I do gives an unacceptable long delay, like saving, starting to debug, ending debug session, switching between design and code view, and doing WinForms designing. I have some parts of my home directory on a mapped network drive. I suspect that that might be a part of the problem. Is it possible to configure VS 2010 to use exclusively local disk for its "internal" work perhaps? Any hints would be appreciated! Has anyone else experienced these kinds of problems?

• Using PostRequestHandlerExecute, Flush and Close to clean up after a request - why is this bad?

  - by Erwin

  After some requests I need to clean up after the user - by calling a remote web service to release some resources if I guess the user doesn't need them anymore. It is ok to leave them hanging and letting them time out on the other server, but the polite thing to do is to inform it that I do not need them anymore. I do not want to waste the users time waiting for cleaning - so I tried to find place to put it. First I tried Application_EndRequest, but I needed something later. Then I found PostRequestHandlerExecute which seemed like a nice place, but I still need a Flush and Close to release the connection to the user. Protected Sub Application_PostRequestHandlerExecute(ByVal sender As Object, ByVal e As System.EventArgs) Response.Flush() Response.Close() ' Simulation of clean up activity: System.Threading.Thread.Sleep(4000) ' Really a couple of web service calls End Sub Is there some other place I could put these lengthy clean up routines?

• How to show validation messages in MVC?

  - by Ian Boyd

  When a user tries to click:        Save and they have entered in some invalid data, i want to notify them. This can be with methods such as: directing their attention to the thing that needs their attention with a balloon hint automatically dropping down a combo-box triggering an animation showing a modal dialog box etc What is the mechanism where a controller tells the view to show a validation message for some controls, given that different views have different notification methods? p.s. the controller doesn't know the order that controls are physically arranged in the view (e.g. LTR locale wants to notify the user in a top-down-left-to-right visual order, while RTL locale wants to notify the user in a bottom-up-right-to-left order)

• Is it possible to Embed Gecko or Webkit in a Windows Form just like a WebView?

  - by Martín Marconcini

  Hi, I'd love to know if there is such thing as a Gecko.NET ;) I mean, just like we can embed a WebView and that is an "instance" of IE7 inside any Windows Forms application (and tell it to "navigateto (fancy_url);", I'd love to use FireFox or WebKit. Anybody tried this? UPDATE: Please bear in mind that although it is possible to embed gecko using the mentioned controls, it is still impossible to print while using gecko. UPDATE March 2010: It’s still not possible to print natively using GeckoFX, however a couple of methods exist that may be enough, depending upon what you’re trying to do. See: http://geckofx.org/viewtopic.php?id=796 for more information.

• Site Actions menu in SharePoint is WSS-like, whereas I have installed MOSS

  - by Graeme

  I had WSS installed on my VM and then uninstalled in order to install MOSS Enterprise I can see a lot of the MOSS stuff in the Central Administration pages but when I create a new web application and site collection, my Site Actions dropdown is showing the WSS version, i.e. Create, Edit Page and Site Settings as opposed to the MOSS menu which has View All Site Content, View Reports, Manage Content and Structure etc. I just tried deleting my web app and creating it all again but it's come back with the same thing again. Is somewhere remembering that I used to have WSS installed? (yes I know MOSS is built on top of WSS but you know what I mean!)

• How can I dynamically set the event handler for a TabItem when it is selected?

  - by juharr

  In XAML you can do <TabItem Selector.Selected="myEvenHandler"></TabItem> to set the event handler for when that tab is selected. How can I do the exact same thing dynamically. I would prefer not to use the SelectionChanged event of TabControl if I can help it. Clearly there is a Selected event on the TabItem I just cannot seem to get at it in code. Here's what I'd like to do. TabItem item = new TabItem(); MyCustomControl mcc = new MyCustomControl(); item.Content = mcc; item.Selected += (s,e) => // This event does not exist { selectedControl = mcc; } myTabControl.Items.Add(item);

• Python: Which encoding is used for processing sys.argv?

  - by EOL

  What encoding are the elements of sys.argv in, in Python? are they encoded with the sys.getdefaultencoding() encoding? sys.getdefaultencoding(): Return the name of the current default string encoding used by the Unicode implementation. PS: As pointed out in some of the answers, sys.stdin.encoding would indeed be a better guess. I would love to see a definitive answer to this question, though, with pointers to solid sources! PPS: As Wim pointed out, Python 3 solves this issue by putting str objects in sys.argv (if I understand correctly). The question remains open for Python 2.x, though. Under Unix, the LC_CTYPE environment variable seems to be the correct thing to check, no? What should be done with Windows (so that sys.argv elements are correctly interpreted whatever the console)?

• iPhone SDK Push Notification

  - by Craig

  I have setup push notifications in the apple developer panel and added the code to my application. It works fine on the phone using a development profile but if I use a distribution (ad-hoc) profile so that I can give it to a few users for testing it gives an error and crashes, the log gives the following error Code: Thu Jun 25 22:22:35 unknown SpringBoard[729] <Warning>: *** Assertion failure in -[SBRemoteNotificationServer registerApplication:forEnvironment:withTypes:], /SourceCache/SpringBoard/SpringBoard-919.5/SBRemoteNotificationServer.m:633 Thu Jun 25 22:22:35 unknown SpringBoard[729] <Error>: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'no connection found for environment production' I am using the following code in the app Code: [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)]; The thing I don't understand is why it works perfectly using a development profile but with ad-hoc it crashes. Does anyone know what would cause this?, I've tried changing lots of things to try and find the issue but have found nothing.

• Redirect console input and output to a textbox.

  - by Peter

  Hi there and thanking in advance I am trying (very hard) to redirect Console input and output into a textbox. So far output is working fine but the trouble is with input. For example I cannot execute a simple program that will do the following: Console.WriteLine("Please enter your name: "); string name = Console.ReadLine(); Console.WriteLine("Hi there " + name); The reason I can't achieve this is because that the program has to stop while waiting for user to type his/her name and press enter. If I wait for user input on a new thread then the main GUI thread freezes and the textbox can never receive the KeyPress. This thing has me totally stumped. Any advice (or better still code) would be greatly appreciated. Cheers
