• WinForms TabControl: How to avoid tab-rendering on DrawMode=OwnerDrawFixed?

  - by splattne

  I extended the (WindowsForms) built-in TabControl in order to implement closing tabs right on the tab itself ("x" image on the right like in Webbrowsers). The inherited control renders the text and images. Also, it uses visual styles on hover etc. All works very well, but I have one problem I can't solve. When the tabs are rendered, I cannot avoid that the Control paints the tabs another time as seen in this screenshot: That's a problem for two reasons: It looks ugly on the selected tab I'd like to increase the tabs' width because the current width doesn't take account of the "x" image on the right Any idea how to solve this?

• micro-SD card initialization using SPI interface

  - by Ron

  I'm using a micro-SD card in an embedded design. The card is connected to a microcontroller using the SPI interface. It worked fine for all cards I've used before, but now my new card will not initialize. The card is a Transcend 2GB micro-SD card (TS2GUSD). After sending the initial clock train to switch to SPI mode I do the following: 1) CMD0 (Argument 0, CRC 0x95) - Response 0x01 - OK 2) CMD8 (Argument 0x000001AA, CRC 0x87) - Response 0x01 0x000001AA - Means it's SDC V2+ card, the Voltage range 2.7V~3.6V is supported - OK Then I should send the ACMD41 command, but when sending the CMD55 (argument 0, CRC 0) that must precede CMD41, I get response 0x05 - Illegal Command. I've also tried to send CMD1 (for MMC cards), but it gives a similar Illegal Command response. The code works fine with my Sandisk 2GB micro-SD card. Does anyone have any idea? Thanks, -Ron-

• django modelformset - one form per related table row

  - by Toby

  Hello, I have two models: class Model1(): name = CharField() url = CharField() class Model2(): model1 = ForeignKey(Model1) user = ForeignKey(User) zzz = CharField() There are 5 rows for model1 in the database, these are fixed and will rarely change. I need to display a formset for model2 that allows users to enter the zzz value, the formset must always show one form per row in the model1 table, the label for each form in the formset must be the name of the related model1. If the user deletes a model2 in the formset the next time the page loads it will render an empty zzz value for that form and the user must be able to edit the previous zzz value - meaning it must be pre populated with all model2 rows associated with the user. The idea is to print each row in the model1 table as a form instead of the user selecting the related model1 name in a select box. I know its not that complicated, but I'm seriously stumped and keep going round in circles!! Many thanks in advance.

• Figuring Out Memory Leaks without Clang

  - by RoLYroLLs

  I'm trying to see if I can find some leaks myself in Apple's TopSongs app. Can someone help me out in at least one and how to identify what is in the Leaks reports and how I can get an idea on finding them? ie: I got one like this: # Category Event Type Timestamp Address Size Responsible Library Responsible Caller 0 GeneralBlock-448 Malloc 00:02.185 0x3f41220 448 libxml2.2.dylib xmlNewParserCtxt From what I can tell, the method xmlNewParserCtxt is the problem, and it's not releasing an object, hence Malloc. The responsible library tells me it's the libxml2.2.dylib library with the problem, which I can't edit. Am I heading in the right direction? If so, half the leaks are in that library and well, i can't edit that.

• Removing Left Recursion in ANTLR

  - by prosseek

  As is explained in http://stackoverflow.com/questions/2652060/removing-left-recursion , there are two ways to remove the left recursion. Modify the original grammar to remove the left recursion using some procedure Write the grammar originally not to have the left recursion What people normally use for removing (not having) the left recursion with ANTLR? I've used flex/bison for parser, but I need to use ANTLR. The only thing I'm concerned about using ANTLR (or LL parser in genearal) is left recursion removal. In practical sense, how serious of removing left recursion in ANTLR? Is this a showstopper in using ANTLR? Or, nobody cares about it in ANTLR community? I like the idea of AST generation of ANTLR. In terms of getting AST quick and easy way, which method (out of the 2 removing left recursion methods) is preferable?

• Best Non-Microsoft/.NET Development Blogs and Podcasts

  - by Mark Lubin

  I really don't want to rile anyone's feathers and I really enjoy blogs like Joel, Coding Horror, Scott Hanselman, etc. However, what are some good blogs/podcasts that focus on other platforms besides Microsoft based ones or maybe even no particular platform at? In particular I am interested in areas like Python, Ruby, Java, C, but any area besides Microsoft fits the bill. There may be other similar questions to this but I think this one is unique since we might get some answers we wouldn't see otherwise, that is, everyone knows Coding Horror is great. Please try to refrain from religious debates; the content of the blog is more important than the platform they are talking about, I just want to get an idea of what is out there and worth the time.

• Variants recursively uses itself?

  - by Mason Wheeler

  I'm trying to build a debug version of rtl140.bpl to make debugging apps with runtime packages easier. I built the DPK and ran DCC32 on it, and it gets a ways in, then dies. C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\source\Win32\rtl\sys\Variants.pas(1072) Fatal: F2092 Program or unit 'Variants' recursively uses itself But looking at Variants.pas, I can't see how. It only uses SysUtils and Types in the interface section, and neither of those use Variants, or use anything that uses Variants. Does anyone have any idea why this is breaking?

• WCF CreateMessage from custom body xml

  - by Cecil

  I have the following code: string body = "<custom xml>"; XDocument doc = XDocument.Parse(body); MemoryStream stream = new MemoryStream(); XmlWriter writer = XmlWriter.Create(stream); if (writer != null) { doc.Save(writer); writer.Flush(); writer.Close(); } stream.Position = 0; XmlReader rd = XmlReader.Create(stream); Message output = Message.CreateMessage(msg.Version, msg.Headers.Action, rd); output.Headers.CopyHeadersFrom(msg); output.Properties.CopyProperties(msg.Properties); When I try to use the message I get the following error: hexadecimal value 0x02, is an invalid character. Line 1, position 2. Any idea why? And what I can do to fix this?

• Firebird query is crashing with org.firebirdsql.jdbc.FBSQLException: GDS Exception. 335544364. reque

  - by user321395

  I am using JdbcTemplate.queryForInt to insert a Row into the DB, and then get the ID back. The Query is "INSERT INTO metadocs(NAME) values (?) RETURNING METADOCID". If I run the statement in Flamerobin, it works fine. However, if I run it from Java, I get the following error: org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [INSERT INTO metadocs(NAME) values (?)

• iPad popover textfield - resignFirstResponder doesn't dismiss keyboard

  - by mosdev

  I have two text fields email and password. The following code works fine when the fields are presented on a regular view but when they are on a popover, the resignFirstResponder does not work (becomeFirstResponder works). textFieldsShouldReturn was called for both fields. Any idea if I am missing something? Thanks! - (BOOL)textFieldShouldReturn:(UITextField *)theTextField { if (theTextField == email) { [password becomeFirstResponder]; return NO; } [theTextField resignFirstResponder]; return NO; }

• Copying the bitmap contents of a UIView's context to that of another UIView

  - by Joonas Trussmann

  Basically what I want to do is copy the already rendered content (a PDF drawn into the UIView's graphics context using CGContextDrawPDFPage()) onto a similar UIView, without having to re render the PDF. The idea is, that I'd then be able to perform an animated transform on the UIView and later re render the PDF with more accuracy. For both UIViews I'm using a larger-than-screen CATiledLayer to make it easier to rerender the PDF once the user zooms in, if that makes any difference. Any tips? I'm kind of lost here.

• Catches communication exception instead of custom fault exception - WCF

  - by Ismail S

  On Server I'm throwing the exception like this. catch(SqlException exception) { if (exception.Message.Contains("Custom error from stored proc")) { //Exception to be thrown when authentication fails. throw new FaultException<MyServiceFault>(new MyServiceFault { MessageText = exception.Message }); } } And on client end I'm catching the exception catch(FaultException<MyServiceFault> faultException) { } Here is my MyServiceFault [DataContract] public class MyServiceFault { [DataMember] public string MessageText { get; set; } [DataMember] public Guid Id { get; set; } } The problem is that on client, it doesn't go to MyServiceFault catch block instead it goes to communication exception catch block and throws this error System.ServiceModel.CommunicationException: The underlying connection was closed: The connection was closed unexpectedly. ---> System.Net.WebException I've also decorated my service method [FaultContract(typeof(MyServiceFault))] in the interface which is implemented by my service. In my web.config servicebehaviour tag consist <serviceDebug includeExceptionDetailInFaults="true" /> Any idea where I'm going wrong

• Building cURL & libcurl with Visual Studio 2010

  - by KTC

  With the help of question #197444, I have managed to build cURL & libcurl from source on Windows from within the Visual Studio 2010 IDE, OpenSSL 1.0.0, and zlib 1.2.5. The problem I see is that at the moment, if I run the resulting curl.exe with the argument -V, then the version that it report is curl 7.20.1 (i386-pc-win32) libcurl/7.20.1 OpenSSL/0.9.8d zlib/1.2.3 Protocols: dict file ftp ftps http https imap imaps ldap pop3 pop3s rtsp smtp smtps telnet tftp Features: AsynchDNS Largefile NTLM SSL libz Note the versions reported for both OpenSSL & zlib doesn't match if what I actually used. Any idea on how to fix this? p.s. Is there a clear list of optional components that can be compiled into libcurl and what options/preprocessor directive to use? (e.g. SSPI, libidn, ...?)

• Seamless jQuery Marquee?

  - by Pez Cuckow

  Is it possible to create a 100% seamless marquee in jQuery (or just javascript but jQuery prefered)? I've made a simple marquee that moves left until it is off the screen then simply jumps (when out of view) to the right and starts again. However I would love it to not have the wait. The only way I could think of doing this would be to duplicate the text and put it after the first text, then swap them round again. However I have no idea how to implement this in jQuery. Any ideas?

• Django-Registration & Django-Profile, using your own custom form

  - by Issy

  Hey All, I am making use of django-registration and django-profile to handle registration and profiles. I would like to create a profile for the user at the time of registration. I have created a custom registration form, and added that to the urls.py using the tutorial on: http://dewful.com/?p=70 The basic idea in the tutorial is to override the default registration form to create the profile at the same time. forms.py - In my profiles app from django import forms from registration.forms import RegistrationForm from django.utils.translation import ugettext_lazy as _ from profiles.models import UserProfile from registration.models import RegistrationProfile attrs_dict = { 'class': 'required' } class UserRegistrationForm(RegistrationForm): city = forms.CharField(widget=forms.TextInput(attrs=attrs_dict)) def save(self, profile_callback=None): new_user = RegistrationProfile.objects.create_inactive_user(username=self.cleaned_data['username'], password=self.cleaned_data['password1'], email=self.cleaned_data['email']) new_profile = UserProfile(user=new_user, city=self.cleaned_data['city']) new_profile.save() return new_user In urls.py from profiles.forms import UserRegistrationForm and url(r'^register/$', register, {'backend': 'registration.backends.default.DefaultBackend', 'form_class' : UserRegistrationForm}, name='registration_register'), The form is displayed, and i can enter in City, however it does not save or create the entry in the DB.

• Improving ANTLR DSL parse-error messages

  - by Dan Fabulich

  I'm working on a domain-specific language (DSL) for non-programmers. Non-programmers make a lot of grammar mistakes: they misspell keywords, they don't close parentheses, they don't terminate blocks, etc. I'm using ANTLR to generate my parser; it provides a nifty mechanism for handling RecognitionExceptions to improve error handling. But I'm finding it pretty hard to develop good error-handling code for my DSL. At this point, I'm considering ways to simplify the language to make it easier for me to provide users with high-quality error messages, but I'm not really sure how to go about this. I think I want to reduce the ambiguity of errors somehow, but I'm not sure how to implement that idea in a grammar. In what ways can I simplify my language to improve parse-error messages for my users? EDIT: Updated to clarify that I'm interested in ways to simplify my language, not just ANTLR error-handling tips in general. (Though, thanks for those!)

• Automapper use in a MVVM application

  - by Echiban

  I am building a MVVM application. The model / entity (I am using NHibernate) is already done, and I am thinking of using AutoMapper to map between the ViewModel and Model. However this clause scares the jebus out of me: (from http://www.lostechies.com/blogs/jimmy_bogard/archive/2009/01/22/automapper-the-object-object-mapper.aspx) Blockquote AutoMapper enforces that for each type map (source/destination pair), all of the properties on the destination type are matched up with something on the source type To me, the logical choice is to map from model to viewmodel, (and I'll let viewmodel manually assign to model), but the quote basically kills the idea since the viewmodel will definitely have properties that don't exist on the model. How have you been using Automapper in a MVVM app? Please help!

• why is there no interface file with silverlight enabled wcf services

  - by Ralph Shillington

  Using Visual Studio 2010 when creating a wcf service the template creates a class file, svc endpoint and an interface file. Why is it that when adding a silverlight-enabled wcf service they don't follow this pattern. As discussed here this seems like a bad idea. After adding the silverlight-enabled service, should one go back and incorporate the interface as discussed in the referenced article. If so, then would it not be as simple to start with a simple WCF service, bypassing the whole "silverlight-enabled" bits altogether.

• INetCfgComponent::RaisePropertyUi arguments

  - by Soo Wei Tan

  I'm trying to do some COM interop and attempting to invoke the INetCfgComponent::RaisePropertyUi method. I've gotten to the point where I can enumerate devices and get a valid INetCfgComponent for the adapter that I want to display the UI for. However, I'm a COM newbie (let alone COM interop) so I have no idea what the third argument in RaisePropertyUi() is meant to be. I've tried passing in the INetCfgComponent object that I have, but that just results in a InvalidCastException. MSDN has the following to say about the argument: Pointer to the IUnknown interface. RaisePropertyUi retrieves from IUnknown the interface of the context in which to display a network component's property sheet. RaisePropertyUi uses this interface to restrict the display of the property sheet to the context of a connection.

• problem with XAMPP, access forbidden... looking for d:\xampp not c:\xampp

  - by pfunc

  I have been using xampp for a while now without any problem. All of a sudden I start xampp today and I am getting an "Error 403 Access Forbidden" when I try to go to my Localhost. When I check the error logs for apache it says: [Mon Mar 22 21:48:57 2010] [error] [client 127.0.0.1] client denied by server configuration: D:/xaamp This is strange, it should first of all say "C:" and second of all say "Xampp" (not xaamp). Where would I change this is my config files. Have no idea how this could have happened.

• xperf won't use my DLL's pdb

  I'm attempting to use xperf to profile my (unmanaged) DLL which is loaded by another (managed) application. Basically, xperf isn't loading the symbols for my DLL; in the CPU usage summary, my DLL's function column says 'Unknown' xperf gives me: xperf: Using symbol path: C:\app\mydll\releaseu;SRV*c:\symbols*http://msdl.microsoft.com/download/symbols xperf: Using executable path: C:\app\mydll\releaseu;SRV*c:\symbols*http://msdl.microsoft.com/download/symbols xperf: Using SymCache path: \SymCache Where C:\app\mydll\releaseu is where my DLL's .pdb file is located. Using xperf -symbols or clicking Load Symbols in the viewer doesn't load my DLL's symbols. A folder for mydll isn't created in C:\Symbols, I'm only getting the symbols from Microsoft. Any idea how to make it work?
