  • Tool for braceless, whitespace sensitive C syntax

    - by Ollie Saunders
    I'm writing some C at the moment and because I like whitespace sensitive syntax, I'd like to write it like this: #include <stdio.h> int main(void) printf("Hello, world!") return 0 Instead of this: #include <stdio.h> int main(void) { printf("Hello, world!"); return 0; } Does anybody know of a tool that will convert the former into the latter? Edit: I've really no interest in arguing with those that think this is a bad idea. By all means continue to think that, you have your reasons. But at least know this: I'm aware Python is a whitespace sensitive language but I have not used it. Why would I? I know Ruby already. Also know: I am not just learning C for the first time and I have used PHP and JavaScript for more than four years, so I am not requesting this out of some personal difficulty, lack of familiarity with block syntax, or dogmatic affiliation. I am also aware of what would be involved in writing one of these and that's not beyond my ability but I don't want this enough to justify spending the time writing one.

  • Why is my Python OpenGL render2DTexture function so slow?

    - by Barakat
    SOLVED: The problem was actually using time.time() every CPU cycle to see whether the next frame should be drawn or not. The time it takes to execute time.time() was having an impact on the FPS. I made this function for drawing 2D textures as images in a 2D view in my OpenGL application. After doing some testing I found that it takes up 1-2 fps per texture. I know I am probably doing something wrong in this code. Any ideas? I am limiting the FPS to 60. Edit: When I disable the texture rendering it adds about 15% fps back. When I disabled text rendering it adds about 15% fps back. When i disable both barely any fps is consumed anymore. IE: 20 out of 60 fps with both on. 30 out of 60 when one is disabled. 58 out of 60 when both are disabled. When rendering the text on a button ( the control I'm using to test this ), it only "prepares" the text when the button label is set. Updated code, still running at the same speed but still works the same: def render2DTexture( self, texture, rect, texrect ): glEnable( GL_TEXTURE_2D ) glBindTexture( GL_TEXTURE_2D, texture ) glBegin( GL_QUADS ) glTexCoord2f( texrect.left, texrect.bottom ) glVertex2i( rect.left, self.windowSize[1] - rect.top ) glTexCoord2f( texrect.right, texrect.bottom ) glVertex2i( rect.left + rect.right, self.windowSize[1] - rect.top ) glTexCoord2f( texrect.right, texrect.top ) glVertex2i( rect.left + rect.right, self.windowSize[1] - ( rect.top + rect.bottom ) ) glTexCoord2f( texrect.left, texrect.top ) glVertex2i( rect.left, self.windowSize[1] - ( rect.top + rect.bottom ) ) glEnd() glDisable( GL_TEXTURE_2D ) def prepareText( self, text, fontFace, color ): self.loadFont( fontFace ) bmp = self.fonts[ fontFace ].render( text, 1, color ) return ( pygame.image.tostring( bmp, 'RGBA', 1 ), bmp.get_width(), bmp.get_height() ) def renderText( self, pText, position ): glRasterPos2i( position[0], self.windowSize[1] - ( position[1] + pText[2] ) ) glDrawPixels( pText[1], pText[2], GL_RGBA, GL_UNSIGNED_BYTE, pText[0] )

  • How to emulate "-lib foo.jar" from _within_ build.xml

    - by Thorbjørn Ravn Andersen
    By specifying "-lib foo.jar" to ant I get the behaviour that the classes in foo.jar is added to the ant classloader and are available for various tasks taking a class name argument. I'd like to be able to specify the same behaviour but only from inside build.xml (so we can do this on a vanilla ant). For taskdefs we have functioning code looking like: <taskdef resource="net/sf/antcontrib/antlib.xml" description="for/foreach tasks"> <classpath> <pathelement location="${active.workspace}/ant-contrib-1.X/lib/ant-contrib.jar" /> </classpath> </taskdef> where the definition is completely provided from the ant-contrib.jar listed. What is the equivalent mechanism for the "global" ant classpath? (I have thought out that this is the way to get <javac> use ecj-3.5.jar to compile with on a JRE - http://stackoverflow.com/questions/2364006/specifying-the-eclipse-compiler-completely-from-within-build-xml - in a way compatible with ant 1.7. Better suggestions are welcome :) EDIT: It appears that the about-to-be-released version 1.0 of ant4eclipse includes ecj. This does not answer the question, but may solve my basic problem.

  • Multiuser login into winforms application

    - by schoetbi
    Hi there, i have a winforms app in C# that needs access control for certain forms. That means, the application is running under the same (default) user at system startup, but certain forms need to be secured, so that only certain windows users could have access to the additional functions after identifying themself with username and password. For that step windows authentication should be used. Now the tricky part. Although the application was started under a "normal" user I would like the superusers to "login" into the special form without restarting the entiere application. My question now is. Is this possible (i.e. create one thread with the credentials of an administrator). Or do I need to setup another appdomain for that? Please give me a hint wather the user of a running application could be changed somehow. Thank you. EDIT I replaced administrators by "certain users" since the privileged user could be just another ordinary user that is granted access to the special functionality by the configuration of the installation.

  • Python Socket Getting Connection Reset

    - by Ian
    I created a threaded socket listener that stores newly accepted connections in a queue. The socket threads then read from the queue and respond. For some reason, when doing benchmarking with 'ab' (apache benchmark) using a concurrency of 2 or more, I always get a connection reset before it's able to complete the benchmark (this is taking place locally, so there's no external connection issue). class server: _ip = '' _port = 8888 def __init__(self, ip=None, port=None): if ip is not None: self._ip = ip if port is not None: self._port = port self.server_listener(self._ip, self._port) def now(self): return time.ctime(time.time()) def http_responder(self, conn, addr): httpobj = http_builder() httpobj.header('HTTP/1.1 200 OK') httpobj.header('Content-Type: text/html; charset=UTF-8') httpobj.header('Connection: close') httpobj.body("Everything looks good") data = httpobj.generate() sent = conn.sendall(data) def http_thread(self, id): self.log("THREAD %d: Starting Up..." % id) while True: conn, addr = self.q.get() ip, port = addr self.log("THREAD %d: responding to request: %s:%s - %s" % (id, ip, port, self.now())) self.http_responder(conn, addr) self.q.task_done() conn.close() def server_listener(self, host, port): self.q = Queue.Queue(0) sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.bind( (host, port) ) sock.listen(5) for i in xrange(4): #thread count thread.start_new(self.http_thread, (i+1, )) while True: self.q.put(sock.accept()) sock.close() server('', 9999) When running the benchmark, I get totally random numbers of good requests before it errors out, usually between 4 and 500. Edit: Took me a while to figure it out, but the problem was in sock.listen(5). Because I was using apache benchmark with a higher concurrency (5 and up) it was causing the backlog of connections to pile up, at which point the connections started getting dropped by the socket.

  • unable to place breakpoints in eclipse

    - by anjanb
    I am using eclipse europa (3.5) on windows vista home premium 64-bit using JDK 1.6.0_18 (32 BIT). Normally, I am able to put breakpoints just fine; However, for a particular class which is NOT part of the project (this class is inside a .JAR file (.JAR file is part of the project) ), although I have attached a source directory to this .JAR file, I am unable to place a breakpoint in this class. If I double-click on the breakpoint pane(left border), I notice that a class breakpoint is placed. I was wondering if there was NO debug info; However, found that this particular class was compiled using ant/javac task using debug="true" and debuglevel="lines,vars,source". I even ran jad on this class to confirm that it indeed contained the debug info. So, why is eclipse preventing me from placing a breakpoint ? EDIT : Just so everyone understands the context, this is a webapp running under tomcat 6.0. I am remote debugging the application from eclipse after having started tomcat outside. The application is working just fine. I am trying to understand the behavior of the above class which I'm unable to do since eclipse is not letting me set a BP. P.S : I saw a few threads here talking about BPs not being hit but in my case, I am unable to place the BP! P.P.S : I tried JDK 1.6.0_16 before trying out 1.6.0_18. Thanks for any pointers.

  • Programmatically modifying a file on Windows Server 2008 (Web Ed.)

    - by Tom
    I have written a .NET 2008 application, incorporating Microsoft.Office.Interop.Excel, that modifies an existing Excel 2007 spreadsheet. It works perfectly on my WinXP development computer. When I upload the app to a Microsoft Web Server 2008, it opens the file and reads from the file, but when the app tries to save the file, it throws this exception: "System.Runtime.InteropServices.COMException (0x800A03EC): 'july2009.xlsx' is read-only. To save a copy, click OK, then give the workbook a new name in the Save As dialog box." The file is NOT read-only, nor is it opened by any other user or app. The app and the Excel file both reside on the D: (data-only) drive. My first instinct was to look at file permissions. When nothing else worked, I literally created a temporary Group, added EVERY user and security entity to it and granted the group full control of the entire D: drive. No luck. Then I tried manually elevating the permission by running my app as administrator. No luck. Finally, I copied the file to my XP development computer and ran the app there. Of course it worked perfectly. Can anyone please tell me how to give my program permission to edit a file on Server 2008? Thanks!

  • Data Binding to an object in C#

    - by Allen
    Objective-c/cocoa offers a form of binding where a control's properties (ie text in a textbox) can be bound to the property of an object. I am trying to duplicate this functionality in C# w/ .Net 3.5. I have created the following very simple class in the file MyClass.cs: class MyClass { private string myName; public string MyName { get { return myName; } set { myName = value; } } public MyClass() { myName = "Allen"; } } I also created a simple form with 1 textbox and 1 button. I init'd one instance of Myclass inside the form code and built the project. Using the DataSource Wizard in Vs2008, i selected to create a data source based on object, and selected the MyClass assembly. This created a datasource entity. I changed the databinding of the textbox to this datasource; however, the expected result (that the textbox's contents would be "allen") was not achieved. Further, putting text into the textbox is not updating the name property of the object. I know i'm missing something fundamental here. At some point i should have to tie my instance of the MyClass class that i initialized inside the form code to the textbox, but that hasn't occurred. Everything i've looked at online seems to gloss over using DataBinding with an object (or i'm missing the mark entirely), so any help is great appreciated. ----Edit--- Utilizing what i learned by the answers, i looked at the code generated by Visual Studio, it had the following: this.myClassBindingSource.DataSource = typeof(BindingTest.MyClass); if i comment that out and substitute : this.myClassBindingSource.DataSource = new MyClass(); i get the expected behavior. Why is the default code generated by VS like it is? Assuming this is more correct than the method that works, how should i modify my code to work within the bounds of what VS generated?

  • C# : changing listbox row color?

    - by Meko
    HI. I am trying to changing backround colorof some rows on listbox.I have 2 list that one has all names and it shown on listbox.And second list has some same value with first list.I want to show that when clicking button it will search in listbox and in second list then will change color where found value. I may search in list box like for (int i = 0; i < listBox1.Items.Count; i++) { for (int j = 0; j < students.Count; j++) if (listBox1.Items[i].ToString().Contains(students[j].ToString())) { } } But I don't know which method to change appearances of row.Any help? *EDIT: * HI I made my code like private void ListBox1_DrawItem(object sender, DrawItemEventArgs e) { e.DrawBackground(); Graphics g = e.Graphics; Brush myBrush = Brushes.Black; Brush myBrush2 = Brushes.Red; g.FillRectangle(new SolidBrush(Color.Silver), e.Bounds); e.Graphics.DrawString(listBox1.Items[e.Index].ToString(), e.Font, myBrush, e.Bounds, StringFormat.GenericDefault); for (int i = 0; i < listBox1.Items.Count; i++) { for (int j = 0; j < existingStudents.Count; j++) if (listBox1.Items[i].ToString().Contains(existingStudents[j])) { e.Graphics.DrawString(listBox1.Items[i].ToString(), e.Font, myBrush2, e.Bounds, StringFormat.GenericDefault); } } e.DrawFocusRectangle(); } Now it draws my list on listbox.But when I click button first it shows only student that in list with red color but when I click on listbox it again draws all elements.I want that it will show all element ,when I click button it will show all elements and founded element in list with red color.Whre is my mistake?

  • Which languages support *recursive* function literals / anonymous functions?

    - by Hugh Allen
    It seems quite a few mainstream languages support function literals these days. They are also called anonymous functions, but I don't care if they have a name. The important thing is that a function literal is an expression which yields a function which hasn't already been defined elsewhere, so for example in C, &printf doesn't count. EDIT to add: if you have a genuine function literal expression <exp>, you should be able to pass it to a function f(<exp>) or immediately apply it to an argument, ie. <exp>(5). I'm curious which languages let you write function literals which are recursive. Wikipedia's "anonymous recursion" article doesn't give any programming examples. Let's use the recursive factorial function as the example. Here are the ones I know: JavaScript / ECMAScript can do it with callee: function(n){if (n<2) {return 1;} else {return n * arguments.callee(n-1);}} it's easy in languages with letrec, eg Haskell (which calls it let): let fac x = if x<2 then 1 else fac (x-1) * x in fac and there are equivalents in Lisp and Scheme. Note that the binding of fac is local to the expression, so the whole expression is in fact an anonymous function. Are there any others?

  • Issue using GAE appcfg.py

    - by JustSmith
    I get nothing out of appcfg.py besides the default output. I'm trying to upload some data to my development project with no luck at at all. From the instructions on the Google App Engine page the steps are as follows: Edit app.yaml update with appcfg.py make upload script upload with appcfg.py After step one I try to run the update and it never shows any success. The following commands product the same output: appcfg.py appcfg.py update appDir appcfg.py update appDir/ appcfg.py update /appDir If i try to follow the instructions from the appcfg.py output and type help upload and get: "help <action>" I get a response from the system, This command is not supported by the help utility. Try "update /?". cause I'm calling the system help command. If I use the command appcfg.py help upload I get the same result as just typing appcfg.py Can someone show me examples of the syntax to update the dev site, upload data to it and get appcfg.py to actually give help on its commands? Also I'm just assuming that the upload script and the .csv file that are being uploaded are in they myApp directory. Appreciate any help,

  • How can I put double quotes inside a string within an ajax JSON response from php?

    - by karlthorwald
    I receive a JSON response in an Ajax request from the server. This way it works: { "a" = "1", "b" = "hello 'kitty'" } But I did not succeed in putting double quotes around kitty. When I convert " to \x22 in the Ajax response, it is still interpreted as " by JavaScript and I cannot parse the JSON. Should I also escape the \ and unescape later (which would be possible)? How to do this? Edit: I am not sure if i expressed it well: I want this string inside of "b" after the parse: hello "kitty" If necessary I could also add an additional step after the parse to convert "b", but I guess it is not necessary, there is a more elegant way so this happens automatically? Edit2: The ajax page is generated by php. I tried several things now to create the value of b, all result in JSON parse error on the page: $b = 'hello "kitty"'; // no 1: //$b = str_replace('"',"\x22",$b); // or no 2: // $b = addslashes($b); // or no 3: //$b = str_replace('"','\"',$b); // or no 4: $b = str_replace('"','\\"',$b); echo '"b" : "' . $b . '"';

    I need to use inheritance with EF4 and the TPH model created from DB. I created a new projet to test simples classes. There is my class model: There is my table in SQL SERVER 2008 : VEHICLE ID : int PK Owner : varchar(50) Consumption : float FirstCirculationDate : date Type : varchar(50) Discriminator : varchar(10) I added a condition in my EDMX on the Discriminator field to differentiate the Scooter, Car, Motorbike and Bike entities. MotorizedVehicle and Vehicle are Abstract. But when I compile, this error appears : Error 3032: Problem in mapping fragments starting at lines 78, 85:EntityTypes EF4InheritanceModel.Scooter, EF4InheritanceModel.Motorbike, EF4InheritanceModel.Car, EF4InheritanceModel.Bike are being mapped to the same rows in table Vehicle. Mapping conditions can be used to distinguish the rows that these types are mapped to. Edit : To Ladislav : I try it and error change to become it for all of my entities : Error 3034: Problem in mapping fragments starting at lines 72, 86:An entity is mapped to different rows within the same table.

  • When virtual inheritance IS a good design?

    - by 7vies
    EDIT3: Please be sure to clearly understand what I am asking before answering (there are EDIT2 and lots of comments around). There are (or were) many answers which clearly show misunderstanding of the question (I know that's also my fault, sorry for that) Hi, I've looked over the questions on virtual inheritance (class B: public virtual A {...}) in C++, but did not find an answer to my question. I know that there are some issues with virtual inheritance, but what I'd like to know is in which cases virtual inheritance would be considered a good design. I saw people mentioning interfaces like IUnknown or ISerializable, and also that iostream design is based on virtual inheritance. Would those be good examples of a good use of virtual inheritance, is that just because there is no better alternative, or because virtual inheritance is the proper design in this case? Thanks. EDIT: To clarify, I'm asking about real-life examples, please don't give abstract ones. I know what virtual inheritance is and which inheritance pattern requires it, what I want to know is when it is the good way to do things and not just a consequence of complex inheritance. EDIT2: In other words, I want to know when the diamond hierarchy (which is the reason for virtual inheritance) is a good design

  • When *not* to use prepared statements?

    - by Ben Blank
    I'm re-engineering a PHP-driven web site which uses a minimal database. The original version used "pseudo-prepared-statements" (PHP functions which did quoting and parameter replacement) to prevent injection attacks and to separate database logic from page logic. It seemed natural to replace these ad-hoc functions with an object which uses PDO and real prepared statements, but after doing my reading on them, I'm not so sure. PDO still seems like a great idea, but one of the primary selling points of prepared statements is being able to reuse them… which I never will. Here's my setup: The statements are all trivially simple. Most are in the form SELECT foo,bar FROM baz WHERE quux = ? ORDER BY bar LIMIT 1. The most complex statement in the lot is simply three such selects joined together with UNION ALLs. Each page hit executes at most one statement and executes it only once. I'm in a hosted environment and therefore leery of slamming their servers by doing any "stress tests" personally. Given that using prepared statements will, at minimum, double the number of database round-trips I'm making, am I better off avoiding them? Can I use PDO::MYSQL_ATTR_DIRECT_QUERY to avoid the overhead of multiple database trips while retaining the benefit of parametrization and injection defense? Or do the binary calls used by the prepared statement API perform well enough compared to executing non-prepared queries that I shouldn't worry about it? EDIT: Thanks for all the good advice, folks. This is one where I wish I could mark more than one answer as "accepted" — lots of different perspectives. Ultimately, though, I have to give rick his due… without his answer I would have blissfully gone off and done the completely Wrong Thing even after following everyone's advice. :-) Emulated prepared statements it is!

  • Can't read some attributes with SAX

    - by akappa
    Hi all, I'm trying to parse that document with SAX: <scxml version="1.0" initialstate="start" name="calc"> <datamodel> <data id="expr" expr="0" /> <data id="res" expr="0" /> </datamodel> <state id="start"> <transition event="OPER" target="opEntered" /> <transition event="DIGIT" target="operand" /> </state> <state id="operand"> <transition event="OPER" target="opEntered" /> <transition event="DIGIT" /> </state> </scxml> I read all the attributes well, except "initialstate" and "name"... I get the attributes with the startElement handler, but the size of the attribute list for scxml is zero. Why? How I can overcome that problem? Edit: public void startElement(String uri, String localName, String qName, Attributes attributes){ System.out.println(attributes.getValue("initialstate")); System.out.println(attributes.getValue("name")); } that, when parsing the first tag, doesn't work (prints "null" two times). In fact, attributes.getLength(); evaluates to zero. Thanks

  • How to determine the data type of a CvMat

    - by Chris
    When using the CvMat type, the type of data is crucial to keeping your program running. For example, depending on whether your data is type float or unsigned char, you would choose one of these two commands: cvmGet(mat, row, col); cvGetReal2D(mat, row, col); Is there a universal approach to this? If the wrong data type matrix is passed to these calls, they crash at runtime. This is becoming an issue, since a function I have defined is getting passed several different types of matrices. How do you determine the data type of a matrix so you can always access its data? I tried using the "type()" function as such. CvMat* tmp_ptr = cvCreateMat(t_height,t_width,CV_8U); std::cout << "type = " << tmp_ptr->type() << std::endl; This does not compile, saying "term does not evaluate to a function taking 0 arguments". If I remove the brackets after the word type, I get a type of 1111638032 EDIT minimal application that reproduces this... int main( int argc, char** argv ) { CvMat *tmp2 = cvCreateMat(10,10, CV_32FC1); std::cout << "tmp2 type = " << tmp2->type << " and CV_32FC1 = " << CV_32FC1 << " and " << (tmp2->type == CV_32FC1) << std::endl; } Output: tmp2 type = 1111638021 and CV_32FC1 = 5 and 0

  • Not possible to load DropDownList on FormView from code behind??

    - by tbone
    I have a UserControl, containing a FormView, containing a DropDownList. The FormView is bound to a data control. Like so: <asp:FormView ID="frmEdit" DataKeyNames="MetricCode" runat="server" DefaultMode="Edit" DataSourceID="llbDataSource" Cellpadding="0" > <EditItemTemplate> <asp:DropDownList ID="ParentMetricCode" runat="server" SelectedValue='<%# Bind("ParentMetricCode") %>' /> etc, etc I am trying to populate the DropDownList from the codebehind. If this was not contained in a FormView, I would normally just do it in the Page_Load event. However, that does not work within a FormView, as as soon as I try to do it, accessing the dropdownlist in code, ie: theListcontrol = CType(formView.FindControl(listControlName), System.Web.UI.WebControls.ListControl) ...the data binding mechansim of the FormView is invoked, which, of course, tries to bind the DropDownList to the underlying datasource, causing a *'ParentMetricCode' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value * error, since the DropDownList has not yet been populated. I tried performing the load in the DataBinding() event of the FormView, but then: theListcontrol = CType(formView.FindControl(listControlName), System.Web.UI.WebControls.ListControl) ...fails, as the FormView.Controls.Count = 0 at that point. Is this impossible? (I do not want to have to use a secondary ObjectDataSource to bind the dropdownlist to)

  • Algorithm to see if keywords exist inside a string

    - by rksprst
    Let's say I have a set of keywords in an array {"olympics", "sports tennis best", "tennis", "tennis rules"} I then have a large list (up to 50 at a time) of strings (or actually tweets), so they are a max of 140 characters. I want to look at each string and see what keywords are present there. In the case where a keyword is composed of multiple words like "sports tennis best", the words don't have to be together in the string, but all of them have to show up. I've having trouble figuring out an algorithm that does this efficiently. Do you guys have suggestions on a way to do this? Thanks! Edit: To explain a bit better each keyword has an id associated with it, so {1:"olympics", 2:"sports tennis best", 3:"tennis", 4:"tennis rules"} I want to go through the list of strings/tweets and see which group of keywords match. The output should be, this tweet belongs with keyword #4. (multiple matches may be made, so anything that matches keyword 2, would also match 3 -since they both contain tennis). When there are multiple words in the keyword, e.g. "sports tennis best" they don't have to appear together but have to all appear. e.g. this will correctly match: "i just played tennis, i love sports, its the best"... since this string contains "sports tennis best" it will match and be associated with the keywordID (which is 2 for this example).

The SConstruct code to detect the presence of fltk is: guienv = Environment(CPPFLAGS = '') guiconf = Configure(guienv) if not guiconf.CheckLibWithHeader('lo', 'lo/lo.h','c'): print 'Did not find liblo for OSC, exiting!' Exit(1) if not guiconf.CheckLibWithHeader('fltk', 'FL/Fl.H','c++'): print 'Did not find FLTK for the gui, exiting!' Exit(1) Unfortunately, on my (Gentoo Linux) system, and many others (Linux distributions) this can be quite troublesome if the package manager allows the simultaneous install of FLTK-1 and FLTK-2. I have attempted to modify the SConstruct file to use fltk-config --cflags and fltk-config --ldflags (or fltk-config --libs might be better than ldflags) by adding them like so: guienv.Append(CPPPATH = os.popen('fltk-config --cflags').read()) guienv.Append(LIBPATH = os.popen('fltk-config --ldflags').read()) But this causes the test for liblo to fail! Looking in config.log shows how it failed: scons: Configure: Checking for C library lo... gcc -o .sconf_temp/conftest_4.o -c "-I/usr/include/fltk-1.1 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_THREAD_SAFE -D_REENTRANT" gcc: no input files scons: Configure: no How should this really be done? And to complete my answer, how do I remove the quotes from the result of os.popen( 'command').read()? EDIT The real question here is why does appending the output of fltk-config cause gcc to not receive the filename argument it is supposed to compile?

  • How can I display multiple django modelformset forms in a grouped fieldsets?

    - by JT
    I have a problem with needing to provide multiple model backed forms on the same page. I understand how to do this with single forms, i.e. just create both the forms call them something different then use the appropriate names in the template. Now how exactly do you expand that solution to work with modelformsets? The wrinkle, of course, is that each 'form' must be rendered together in the appropriate fieldset. For example I want my template to produce something like this: <fieldset> <label for="id_base-0-desc">Home Base Description:</label> <input id="id_base-0-desc" type="text" name="base-0-desc" maxlength="100" /> <label for="id_likes-0-icecream">Want ice cream?</label> <input type="checkbox" name="likes-0-icecream" id="id_likes-0-icecream" /> </fieldset> <fieldset> <label for="id_base-1-desc">Home Base Description:</label> <input id="id_base-1-desc" type="text" name="base-1-desc" maxlength="100" /> <label for="id_likes-1-icecream">Want ice cream?</label> <input type="checkbox" name="likes-1-icecream" id="id_likes-1-icecream" /> </fieldset> I am using a loop like this to process the results (after form validation) base_models = base_formset.save(commit=False) like_models = like_formset.save(commit=False) for base_model, likes_model in map(None, base_models, likes_models): which works as I'd expect (I'm using map because the # of forms can be different). The problem is that I can't figure out a way to do the same thing with the templating engine. The system does work if I layout all the base models together then all the likes models after wards, but it doesn't meet the layout requirements. EDIT: Updated the problem statement to be more clear about what exactly I'm processing (I'm processing models not forms in the for loop)

  • WiX: Define made in included file not avaible from wxs-fragment-file.

    - by leiflundgren
    I have a defines.wxi-file which contains some good definitions used in all my wxs-files. When I attempt to reference the defined value from one of the <Fragment>-files I get Undefined preprocessor variable '$(var.IMAGE_FOLDER)' back in my face. I guess there is something trivial I am missing here... Any ideas? Edit 19:th April. Found that issue only occurs if reference from a Fragment-file. Re-wrote sample to match that. defines.wxi <Include> <?define IMAGE_FOLDER="Images" ?> </Include> some-Fragment.wxs <Fragment> <?Include defines.wxi ?> <Component Id='c.Images' Guid=".." Directory='INSTALLDIR.Images' > <File Id='f.sample.jpg' Source='$(var.IMAGE_FOLDER)sample.jpg' Name='sample.jpg' /> </Component>

  • ASP.MVC 2 RTM + ModelState Error at Id property

    - by Zote
    I have this classes: public class GroupMetadata { [HiddenInput(DisplayValue = false)] public int Id { get; set; } [Required] public string Name { get; set; } } [MetadataType(typeof(GrupoMetadata))] public partial class Group { public virtual int Id { get; set; } public virtual string Name { get; set; } } And this action: [HttpPost] public ActionResult Edit(Group group) { if (ModelState.IsValid) { // Logic to save return RedirectToAction("Index"); } return View(group); } That's my view: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Group>" %> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <% using (Html.BeginForm()) {%> <fieldset> <%= Html.EditorForModel() %> <p> <input type="submit" value="Save" /> </p> </fieldset> <% } %> <div> <%=Html.ActionLink("Back", "Index") %> </div> </asp:Content> But ModelState is always invalid! As I can see, for MVC validation 0 is invalid, but for me is valid. How can I fix it since, I didn't put any kind of validation in Id property? UPDATE: I don't know how or why, but renaming Id, in my case to PK, solves this problem. Do you know if this an issue in my logic/configuration or is an bug or expected behavior? Thank you
