• timing of reads from serial port on windows

  - by Marcin K

  I'm trying to implement a protocol over serial port on a windows(xp) machine. The problem is that message synchronization in the protocol is done via a gap in the messages, i.e., x millisecond gap between sent bytes signifies a new message. Now, I don't know if it is even possible to accurately detect this gap. I'm using win32/serport.h api to read in one of the many threads of our server. Data from the serial port gets buffered, so if there is enough (and there will be enough) latency in our software, I will get multiple messages from the port buffer in one sequence of reads. Is there a way of reading from the serial port, so that I would detect gaps in when particular bytes were received?

• generated service mock: everything but RhinoMocks fails?

  - by hko

  I have the "quest" to search for the next Mocking Framework for my company, and basically it's down to NSubstitute (simplest syntax, but no strict mocks), FakeItEasy(best reviews, Roy Osherove bonus, and slightly better lib support than NSubstitute), Moq (best "other libs support", biggest featureset, downside: mock.Object). We definitely want to move on from RhinoMocks, e.g. because of the unusefull interactiontest error messages (it should tell me what the parameter was instead, when a verification fails). So I was pretty surprised the other day (that was yesterday) when I found out RhinoMocks could do a thing where every other mock framework fails at: Mocking an autogenerated SomethingService (a typical VS autogenerated service with a default construtor in a partial class). Please don't argue about the design.. I intend to write lightweight integration tests (and some unit tests), and I can't mess around with the service, the product is installed on too many customers system. See this code: // here the NSubstitute and FakeItEasy equivalents throw an exception.. see below TicketStoreService fakeTicketStoreService = MockRepository.GenerateMock<TicketStoreService>(); fakeTicketStoreService.Expect(service => service.DoSomething(Arg.Is(new Guid())).Return(new Guid()); fakeTicketStoreService.DoSomething(Arg.Is(new Guid())); fakeTicketStoreService.VerifyAllExpectations(); Note that DoSomething is a non-virtual methodcall in an autogenerated class. So it shouldn't work, according to common knowledge. But it does. Problem is that it's the only (non commercial) framework that can do this: Rhino.Mocks works, and verification works too FakeItEasy says it doesn't find a default constructor (probably just wrong exception message): No default constructor was found on the type SomeNamespace.TicketStoreService Moq gives something sane and understandable: Invalid setup on a non-virtual (overridable in VB) member: service=> service.DoSomething Nsubstitute gives a message System.NotSupportedException: Cannot serialize member System.ComponentModel.Component.Site of type System.ComponentModel.ISite because it is an interface. I'm really wondering what's going on here with the frameworks, except Moq. The "fancy new" frameworks seem to have an initial perf hit too, probably preparing some Type cache and serializing stuff, whilst RhinoMocks somehow manages to create a very "slim" mock without recursion. I have to admit I didn't like RhinoMocks very well, but here it shines.. unfortunately. So, is there a way to get that to work with newer (non-commercial!) mocking frameworks, or somehow get a sane error message out of Rhino.Mocks? And why can Rhino.Mocks achieve this, when clearly every Mocking framework states it can only work with virtual methods when given a concrete class? Let's not derail the discussion by talking about alternative approaches like Extract&Override or runtime-proxy Mocking frameworks like JustMock/TypeMock/Moles or the new Fakes framework, I know these, but that would be less ideal solutions, for reasons beyond this topic. Any help appreciated..

• iPhone Simulator Error: dyld: Symbol not found: _objc_collect_if_needed

  - by freespace

  I have been seeing the following error message a lot whenever I run something in the simulator: dyld: Symbol not found: _objc_collect_if_needed Referenced from: /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.sdk/System/Library/Frameworks/Foundation.framework/Foundation Expected in: /usr/lib/libobjc.A.dylib in /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.sdk/System/Library/Frameworks/Foundation.framework/Foundation I am running XCode 3.2.2 on OS X 10.6.3, and have reinstalled the SDK twice with no avail. This error makes running any code on the simulator something of a Russian Roulette, but with 5 out of 6 chambers loaded. I have checked the files mentioned in the error message, and they all checkout as being present. This sometimes go away if I restart XCode. Other times I have to logout, or even restart. And sometimes nothing works. I have googled this, even tried apple's developer forums. Other than a reference to this in the MonoTouch list, this bug appears to be completely unknown otherwise. Anything help would be greatly appreciated - this is a real PITA. Cheers, Steve

• WCF: what timeout property to use?

  - by Tom234

  I have a piece of code like so NetTcpBinding binding = new NetTcpBinding(SecurityMode.Transport); binding.Security.Message.ClientCredentialType = MessageCredentialType.Windows; binding.CloseTimeout = new TimeSpan(0, 0, 1); binding.OpenTimeout = new TimeSpan(0, 0, 1); binding.SendTimeout = new TimeSpan(0, 0, 1); binding.ReceiveTimeout = new TimeSpan(0, 0, 1); EndpointAddress endPoint = new EndpointAddress(new Uri(clientPath)); DuplexChannelFactory<Iservice> channel = new DuplexChannelFactory<Iservice>(new ClientCallBack(clientName), binding, endPoint); channel.Ping() When the endpoint doesn't exist it still waits 20seconds before throwing an EndpointNotFoundException. The weird thing is that when i changed the SendTimeout the exception message changed from The connection attempt lasted for a time span of 00:00:20 to ....01 but still took 20seconds to throw the exception! How can i change this timeout?

• Server-initiated Rendering: EJB -> FacesContext?

  - by egbokul

  I've already asked this question on the Icefaces forum, but meanwhile I realized that this is a more generic problem. I'd like to update parts of a JSF page when I get a message in my MDB. The problem is, how do I get the FacesContext from the EJB container? In the message processing function FacesContext.getCurrentInstance() returns null. I've also tried to make a JSF managed bean be a MDB, but I couldn't (it seems you can't have both in the same class?). Since I'm a beginner in the JSF world I'm kind of stuck now. Is there a way to make it work? (Glassfish v3 + Netbeans 6.8, JSF2 + Icefaces 2.0 alpha2)

• IF Statement has strange behavior

  - by BSchlinker

  I've developed a 'custom' cout, so that I can display text to console and also print it to a log file. This cout class is passed a different integer on initialization, with the integer representing the verbosity level of the message. If the current verbosity level is greater then or equal to the verbosity level of the message, the message should print. The problem is, I have messages printing even when the current verbosity level is too low. I went ahead and debugged it, expecting to find the problem. Instead, I found multiple scenarios where my if statements are not working as expected. The statement if(ilralevel_passed <= ilralevel_set) will sometimes proceed even if ilralevel_set is LESS then ilralevel_passed. You can see this behavior in the following picture (my apologizes for using Twitpic) http://twitpic.com/1xtx4g/full. Notice how ilralevel_set is equal to zero, and ilralevel_passed is equal to one. Yet, the if statement has returned true and is now moving forward to pass the line to cout. I've never seen this type of behavior before and I'm not exactly sure how to proceed debugging it. I'm not able to isolate the behavior either -- it only occurs in certain parts of my program. Any suggestions are appreciated as always. // Here is an example use of the function: // ilra_status << setfill('0') << setw(2) << dispatchtime.tm_sec << endl; // ilra_warning << "Dispatch time (seconds): " << mktime(&dispatchtime) << endl; // Here is the 'custom' cout function: #ifndef ILRA_H_ #define ILRA_H_ // System libraries #include <iostream> #include <ostream> #include <sstream> #include <iomanip> // Definitions #define ilra_talk ilra(__FUNCTION__,0) #define ilra_update ilra(__FUNCTION__,0) #define ilra_error ilra(__FUNCTION__,1) #define ilra_warning ilra(__FUNCTION__,2) #define ilra_status ilra(__FUNCTION__,3) // Statics static int ilralevel_set = 0; static int ilralevel_passed; // Classes class ilra { public: // constructor / destructor ilra(const std::string &funcName, int toset) { ilralevel_passed = toset; } ~ilra(){}; // enable / disable irla functions static void ilra_verbose_level(int toset){ ilralevel_set = toset; } // output template <class T> ilra &operator<<(const T &v) { if(ilralevel_passed <= ilralevel_set) std::cout << v; return *this; } ilra &operator<<(std::ostream&(*f)(std::ostream&)) { if(ilralevel_passed <= ilralevel_set) std::cout << *f; return *this; } }; // end of the class #endif /* ILRA_H_ */

• Disable a style in VCL application

  - by Martin

  I am adding the a VCL style into my application but am also giving the users an option to turn this off but I cannot figure out how to do this globally at runtime. Setting "TStyleManager.AutoDiscoverStyleResources := false" almost works but it pops up with an error message saying "Style {style set} not found" but after dismissing the message does exactly what I want. This code I would expect to work but does not... if (not ParamObj.UseDarkStyle) then begin //TStyleManager.AutoDiscoverStyleResources := false; TStyleManager.SetStyle(TStyleManager.SystemStyle); end; I also tried (originally) TStyleManager.TrySetStyle('Windows'); but this also does not work. I have tried this both sides of "Application.Initialize;" with no difference What am I missing? Thanks in advance, Martin

• Clojure lots of threads

  - by Timothy Baldridge

  I just got done watching Rick Hickey's "Clojure Concurrency" talk, and I have a few questions about threads. Let's say I have a situation with lots of Agents, let's say 10,000 of them running one machine. I'd rather not have 10,000 CPU threads running at once, but I don't want threads to be blocked by the actions of other threads. In this example I won't really be waiting for replies, instead each Agent will be sending a message or two, and then waiting until it gets a message. How would I structure a program like this without getting 10k OS threads which would probably end up slowing the system down.

• Sending email from Drupal contact form, but GMail marks it as "Forged"

  - by James Shields

  Hi, My Drupal site sends email to a GMail account, but the emails sent all go into the Spam folder, and GMail puts up a bar with the message "This message was likely forged and did not originate from your account." Although I can create a filter to prevent them going to Spam, I want to start sending newsletters, and I suspect they'll have the same problem. I suspect the problem is with the way I've set up either PHP or Drupal to send mail. As far as I know it's just using the sendmail function. I've set the from address to "info@..." where ... is the site domain. Any tips on how I can make set up my outgoing mail so it won't be refused by GMail (and presumably other major mail providers)? Thanks, James

• Can I mark an Email as "High Importance" for Outlook using System.Net.Mail?

  - by ccornet

  Part of the application I'm working on for my client involves sending emails for events. Sometimes these are highly important. My client, and most of my client's clients, use Outlook, which has the ability to mark a mail message as High Importance. Now, I know it is callous to assume that all end users will be using the same interface, sp I am not. But considering you can send email from Outlook as High Importance even if the target is not necessarily reading through Outlook, that means that there is basically some data stored... somehow... that lets Outlook know if a particular message was assigned as High Importance. That's my interpretation, at least. The application currently uses System.Net.Mail to send out emails, using System.Net.Mail.MailMessages for writing them and System.Net.Mail.SmtpClient to send them. Is it possible to set this "High Importance" setting with System.Net.Mail's abilities? If not, is there any assembly available which can configure this setting?

• Cannot call scalar-valued CLR UDF from select ... from table statement

  - by Henrik B

  I have created a scalar-valued CLR UDF (user defined function). It takes a timezone id and a datetime and returns the datetime converted to that timezone. I can call it from a simple select without problems: "select dbo.udfConvert('Romance Standard Time', @datetime)" (@datetime is of course a valid datetime variable) But if I call it passing in a datetime from a table it fails: "select dbo.udfConvert('Romance Standard Time', StartTime) from sometable" (column StartTime is of course a column of type datetime) The error message is: "Cannot find either column "dbo" or the user-defined function or aggregate "dbo.udfConvert", or the name is ambiguous." This message is really for beginners that has misspelled something, but as it works in one case and not in the other, I don't think I have done any misspellings. Any ideas?

• What other tool is using my hotkey?

  - by Sammy

  I use Greenshot for screenshots, and it's been nagging about some other software tool using the same hotkey. I started receiving this warning message about two days ago. It shows up each time I reboot and log on to Windows. The hotkey(s) "Ctrl + Shift + PrintScreen" could not be registered. This problem is probably caused by another tool claiming usage of the same hotkey(s)! You could either change your hotkey settings or deactivate/change the software making use of the hotkey(s). What's this all about? The only software I recently installed is CPU-Z Core Temp Speed Fan HD Tune Epson Print CD NetStress What I would like to know is how to find out what other tool is causing this conflict? Do I really have to uninstall each program, one by one, until there is no conflict anymore? I see no option for customizing any hotkeys in CPU-Z, and according to docs there are only a few keyboard shortcuts. These are F5 through F9, but they are no hotkeys. There is nothing in Core Temp, and from what I can see... nothing in Speed Fan. Is any of these programs known to use Ctrl + Shift + PrintScreen hotkey for screenshots? I am actually suspecting the Dropbox client. I think I saw a warning recently coming from Dropbox program, something to do with hotkeys or keyboard shortcuts. I see that it has an option for sharing screenshots under Preferences menu, but I see no option for hotkeys. Core Temp actually also has an option for taking screenshots (F9) but it's just that - a keyboard shortcut, not a hotkey. And again, there's no option actually for changing this setting in Options/Settings menu. How do you resolve this type of conflicts? Are there any general methods you can use to pinpoint the second conflicting software? Like... is there some Windows registry key that holds the hotkeys? Or is it just down to mere luck and trial and error? Addendum I forgot to mention, when I do use the Ctrl + Shift + PrintScreen hotkey, what happens is that the Greenshot context menu shows up, asking me where I want to save the screenshot. So it appears to be working. But I am still getting the darn warning every time I reboot and log on to Windows?! I actually tried changing the key bindings in Greenshot preferences, but after a reboot it seems to have returned back to the settings I had previously. Update I can't see any hotkey conflicts in the Widnows Hotkey Explorer. The aforementioned hotkey is reserved by Greenshot, and I don't see any other program using the same hotkey binding. But when I went into Greenshot preferences, this is what I discovered. As you can see it's the Greenshot itself that uses the same hotkey twice! I guess that's why no other program was listed above as using this hotkey. But how can Greenshot be so stupid to use the same hotkey more than once? I didn't do this! It's not my fault... I'm not that stupid. This is what it's set to right now: Capture full screen: Ctrl + Skift + Prntscrn Capture window: Alt + Prntscrn Capture region: Ctrl + Prntscrn Capture last region: Skift + Prntscrn Capture Internet Explorer: Ctrl + Skift + Prntscrn And this is my preferred setting: Capture full screen: Prntscrn Capture window: Alt + Prntscrn Capture region: Ctrl + Prntscrn Capture last region: Capture Internet Explorer: I don't use any hotkey for "last region" and IE. But when I set this to my liking, as listed here, Greenshot gives me the same warning message, even as I tab through the hotkey entry fields. Sometimes it even gives me the warning when I just click Cancel button. This is really crazy! On the side note... You might have noticed that I have "update check" set to 0 (zero). This is because, in my experience, Greenshot changes all or only some of my preferences back to default settings whenever it automatically updates to a new version. So I opted to stay off updates to get rid of the problem. It has done so for the past three updates or so. I hoped to receive a new update that would fix the issue, but I think it still reverts back to default settings after each update to a new version, including setting default hotkeys. Update 2 I'll give you just one example of how Greenshot behaves. This is the dialog I have in front of me right now. As you can see, I have removed the last two hotkeys and changed the first one to my own liking. While I was clicking in the fields and removing the two hotkeys I was getting the warning message. So let's say I click in the "capture last region" field. Then I get this: Note that none of the entries include "Ctrl + Shift + PrintScreen" that it's warning about. Now I will change all the hotkeys so I get something like this: So now I'm using QWERTY letters for binding, like Ctrl+Alt+Q, Ctrl+Alt+W and so on. As far as I know no Windows program is using these. While I was clicking through the different fields it was giving me the warning. Now when I try to click OK to save the changes, it once again gives me a warning about "ctrl + shift + printscreen". Update 3 After setting the above key bindings (QWERTY) and saving changes, and then rebooting, the conflict seems to have been resolved. I was then able to set following key bindings. Capture full screen: Prntscrn Capture window: Alt + Prntscrn Capture region: Ctrl + Prntscrn I was not prompted with the warning message this time. Perhaps changing key binding required a system reboot? Sounds far fetched but that appears to be the case. I'm still not sure what caused this conflict, but I know for sure that it started after installing aforementioned programs. It might just have to do with Greenshot itself, and not some other program. Like I said, I know from experience that Greenshot likes to mess with users' settings after each update. I wouldn't be surprised if it was actually silently updated, even though I have specified not to check for updates, then it changed the key bindings back to defaults and caused a conflict with the hotkeys that were registered with the operating system previously. I rarely reboot the system, so that could have added to the conflict. Next time if I see this I will run Hotkey Explorer immediately and see if there is another program causing the conflict.

• Is there a limit on the number of mutex objects that can be created in a Windows process?

  - by young-phillip

  I'm writing a c# application that can create a series of request messages. Each message could have a response, that needs to be waited on by a consumer. Where the number of outstanding request messages is constrained, I have used the windows EVENT to solve this problem. However, I know there is a limit on how many EVENT objects can be created in a single process, and in this instance, its possible I might exceed that limit. Does anyone know if there is a similar limit on creation of mutex objects or semaphores? I know this can be solved by some sort of pool of shared resources, that are grabbed by consumers when they need to wait, but it would be more convenient if each request message could have its own sync object.

• Visual Studio 2008. MFC event wizard broken

  - by G Forty

  OK, so it's almost a programming question - The VS2008 dialog event wizard has stopped working. Double-clicking on a button in an MFC dialog project does not fire the wizard as usual and a right-click to get to the 'Add Event Handler...' shows a dialog with no message types. Further to this the MFC message mapping and virtual class listing that generally appears in the properties window (Alt + Enter) is now empty. Has anyone elese seen this and if so, how'd they fix it? I have 'repaired' my VS08 installation ... Thx++ Jerry
