  • django url user id versus userprofile id problem

    - by dana
    hello there, i have a mini comunity where each user can search and find another user profile. Userprofile is a class model, indexed differently compared to user model class (user id is not equal to userprofile id) But i cannot see a user profile by typing in the url the corresponding id. I only see the profile of the currently logged in user. Why is that? I'd also want to have in my url the username (a primary key of the user table also) and NOT the id (a number). The guilty part of the code is: what can i replace that request.user with so that it wil actually display the user i searched for, and not the currently logged in? def profile_view(request, id): u = UserProfile.objects.get(pk=id) cv = UserProfile.objects.filter(created_by = request.user) blog = New.objects.filter(created_by = request.user) return render_to_response('profile/publicProfile.html', { 'u':u, 'cv':cv, 'blog':blog, }, context_instance=RequestContext(request)) in urls (of the accounts app): url(r'^profile_view/(?P<id>\d+)/$', profile_view, name='profile_view'), and in template: <h3>Recent Entries:</h3> {% load pagination_tags %} {% autopaginate list 10 %} {% paginate %} {% for object in list %} <li>{{ object.post }} <br /> Voted: {{ vote.count }} times.<br /> {% for reply in object.reply_set.all %} {{ reply.reply }} <br /> {% endfor %} <a href=''> {{ object.created_by }}</a> <br /> {{object.date}} <br /> <a href = "/vote/save_vote/{{object.id}}/">Vote this</a> <a href="/replies/save_reply/{{object.id}}/">Comment</a> </li> {% endfor %} thanks in advance!

  • vb.net, How can I limit a textchanged event for a textbox to keyboard input only?

    - by Luay
    Hi everyone, Please allow me to explain what I have and what I am trying to achieve. I have a textbox (called txtb1) and a button under it (called btn_browse) on a winform in a vb.net project. When the user clicks the button a folder browser dialog appears. The user selects his desired folder and when he/she clicks 'ok' the dialog closes and the path of the folder selected appears in the textbox. I also want to store that value in a variable to be used somewhere else(the value will be copied to an xml file when the user clicks 'apply' on the form, but this has no effect nor is related to my problem). To achieve that I have the following code: Public myVar As String Private Sub btn_browse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_browse.Click Dim f As New FolderBrowserDialog If f.ShowDialog() = DialogResult.OK Then txtb1.Text = f.SelectedPath End If myVar = txtb1.text f.Dispose() End Sub This part works with no problems. Now, what if the user either: 1- decides to enter the path manually rather than use the browse button. or, 2- after using the browse button and selecting the folder they decide to manually change the location In trying to solve this I added a textchanged event to the textbox as follows: Private Sub txtb1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtb1.TextChanged myVar = txtb1.Text End Sub However, this is not working. Apparently, and I don't know if this is relevant, when the user selects the desired folder using the browse button the textchanged event is also triggered. and when I click on the textbox (to give it focus) and press any keyboard key the application simply stops responding. So my questions are: am I going about this the right way? if my logic is flawed, could someone point me to how usually such a thing could be achieved? is it possible to limit the triggering events to only keyboard input as a way around this? I tried the keydown and keypress events but I am getting the freeze. I would be grateful for your help. Thanks

  • MFC Combo-Box Control is not showing the full list of items when I click the drop-down menu...

    - by shan23
    I'm coding an app in MSVS 2008, which has a ComboBox control which I initialize thru the code as below: static char* OptionString[4] = {"Opt1", "Opt2", "Opt3", "Opt4"}; BOOL CMyAppDlg::OnInitDialog() { CDialog::OnInitDialog(); // Set the icon for this dialog. The framework does this automatically // when the application's main window is not a dialog SetIcon(m_hIcon, TRUE); // Set big icon SetIcon(m_hIcon, FALSE); // Set small icon // TODO: Add extra initialization here m_Option.AddString(OptionString[0]); m_Option.AddString(OptionString[1]); m_Option.AddString(OptionString[2]); m_Option.AddString(OptionString[3]); m_Option.SetCurSel(0); return TRUE; // return TRUE unless you set the focus to a control } Now, when I build the app and click the down-arrow, the drop-down box shows the first option ONLY(since I've selected that thru my code). But, if i press down-arrow key on keyboard, it cycles thru the options in the order I've inserted, but never does it show more than 1 option in the box. So, In case an user wants to select option3, he has to cycle through options 1 and 2 !! Though once I select any option using the keyboard, the appropriate event handlers are fired, I'm miffed by this behaviour , as is understandable. I'm listing the properties of the combo-box control as well - only the properties that are true(rest are set to false): Type - Dropdown Vertical Scrollbar Visible Tabstop This has bugged me for weeks now. Can anyone pls enlighten me ?

  • Squid handling of concurrent cache misses

    - by Oliver H-H
    We're using a Squid cache to off-load traffic from our web servers, ie. it's setup as a reverse-proxy responding to inbound requests before they hit our web servers. When we get blitzed with concurrent requests for the same request that's not in the cache, Squid proxies all the requests through to our web ("origin") servers. For us, this behavior isn't ideal: our origin servers gets bogged down trying to fulfill N identical requests concurrently. Instead, we'd like the first request to proxy through to the origin server, the rest of the requests to queue at the Squid layer, and then all be fulfilled by Squid when the origin server has responded to that first request. Does anyone know how to configure Squid to do this? We've read through the documentation multiple times and thoroughly web-searched the topic, but can't figure out how to do it. We use Akamai too and, interestingly, this is its default behavior. (However, Akamai has so many nodes that we still see lots of concurrent requests in certain traffic spike scenarios, even with Akamai's super-node feature enabled.) This behavior is clearly configurable for some other caches, eg. the Ehcache documentation offers the option "Concurrent Cache Misses: A cache miss will cause the filter chain, upstream of the caching filter to be processed. To avoid threads requesting the same key to do useless duplicate work, these threads block behind the first thread." Some folks call this behavior a "blocking cache," since the subsequent concurrent requests block behind the first request until it's fulfilled or timed-out. Thx for looking over my noob question!

  • Flex 3: should I provide prepared data to my component or make it to process data before display?

    - by grapkulec
    I'm starting to learn a little Flex just for fun and maybe to prove that I still can learn something new :) I have some idea for a project and one of its parts is a tree component which could display data in different ways depending on configuration. The idea There is list of objects having properties like id, date, time, name, description. And sometimes list should be displayed like this: first level: date second level: time third level: name and sometimes like this: first level: year second level: month third level: day fourth level: time and name By level I mean level of nesting of course. So, we can have years, that have months, that have days, that have hours and so forth. The problem What could be the best way to do it? I mean, should I prepare data for different ways of nesting outside of component or even outside of flex? I can do it at web service level in C# where I plan to have database access layer and send to flex nice and ready to display XML or array of objects. But I wonder if that won't cause additional and maybe unneccessary network traffic. I tried to hack some code in my component to convert my data objects into XML or ArrayCollection but I don't know enough of Flex and got stuck on elimination of duplicates or getting specific data by some key value. Usually to do such things I have STL with maps, sets and vectors and I find Flex arrays and even Dictionary a little bit confusing (I've read language reference and googled without any significant luck). The question So, to sum things up: should I give my tree component data prepared just for chosen type of display or should I try to do it internally inside component (or some helper class written in ActionScript)?

  • Autocompleting \cite{} with emacs + auctex gives "cite: no such database entry"

    - by Alejandro Weinstein
    Hi: I am running Emacs 23.1.1 and AucTeX 11.85 in an Ubuntu 8.10 machine. After opening a tex file, the first time I try to use the autocompletion of the \cite{} command, I get "cite: info not available, use `C-c &' to get it." in the minibuffer. After doing the 'C-c &', I get "byte-code: No BibTeX entry with citation key". Subsequent calls to \cite gives me the message "cite: no such database entry" . I have a \bibliography{library} in my tex file, and the \cite{} entries that I did manually work as expected. I have the following in my .emacs (require 'reftex) (setq-default TeX-master nil) (add-hook 'LaTeX-mode-hook 'TeX-PDF-mode) ;turn on pdf-mode. AUCTeX ;will call pdflatex to ;compile instead of latex. (add-hook 'LaTeX-mode-hook 'LaTeX-math-mode) ;turn on math-mode by ;default (add-hook 'LaTeX-mode-hook 'reftex-mode) ;turn on REFTeX mode by ;default (add-hook 'LaTeX-mode-hook 'flyspell-mode) ;turn on flyspell mode by ;default (setq reftex-plug-into-AUCTeX t) (setq TeX-auto-save t) (setq TeX-save-query nil) (setq TeX-parse-self t) (setq-default TeX-master nil) I also tried the suggestions in http://stackoverflow.com/questions/2699017/suggestion-for-cite-in-emacs-with-auctex, but it didn't work either.

  • Ruby - encrypted_strings

    - by Tom Andersen
    A bit of a Ruby newbie here - should be an easy question: I want to use the encrypted_strings gem to create a password encrypted string: (from http://rdoc.info/projects/pluginaweek/encrypted_strings) Question is: Everything works fine, but how come I don't need the password to decrypt the string? Say I want to store the string somewhere for a while,like the session. Is the password also stored with it? (which would seem very strange?). And no, I'm not planning on using 'secret-key' or any similar hack as a password. I am planning on dynamically generating a class variable @@password using a uuid, which I don't store other than in memory, and can change from one running of the program to the next. Symmetric: >> password = 'shhhh' => "shhhh" >> crypted_password = password.encrypt(:symmetric, :password => 'secret_key') => "qSg8vOo6QfU=\n" >> crypted_password.class => String >> crypted_password == 'shhhh' => true >> password = crypted_password.decrypt => "shhhh"

  • WPF: Selecting the Target of an Animation

    - by Phil Sandler
    I am trying to create a simple (I think) animation effect based on a property change in my ViewModel. I would like the target to be a specific textblock in the control template of a custom control, which inherits from Window. From the article examples I've seen, a DataTrigger is the easiest way to accomplish this. It appears that Window.Triggers doesn't support DataTriggers, which led me to try to apply the trigger in the style. The problem I am currently having is that I can't seem to target the TextBlock (or any other child control)--what happens is which the code below is that the animation is applied to the background of the whole window. If I leave off StoryBoard.Target completely, the effect is exactly the same. Is this the right approach with the wrong syntax, or is there an easier way to accomplish this? <Style x:Key="MyWindowStyle" TargetType="{x:Type Window}"> <Setter Property="Template" Value="{StaticResource MyWindowTemplate}"/> <Style.Triggers> <DataTrigger Binding="{Binding ChangeOccurred}" Value="True"> <DataTrigger.EnterActions> <BeginStoryboard> <Storyboard BeginTime="00:00:00" Duration="0:0:2" Storyboard.Target="{Binding RelativeSource={RelativeSource AncestorType=TextBlock}}" Storyboard.TargetProperty="(Background).(SolidColorBrush.Color)"> <ColorAnimation FillBehavior="Stop" From="Black" To="Red" Duration="0:0:0.5" AutoReverse="True"/> </Storyboard> </BeginStoryboard> </DataTrigger.EnterActions> </DataTrigger> </Style.Triggers> </Style>

  • Vim script to TeX source, and launch PDF only if no errors

    - by Jeet
    Hi, I am switching to using Vim for for my LaTeX editing environment. I would like to be able to tex the source file from within Vim, and launch an external viewing if the compile was successful. I know about the Vim-Latex suite, but, if possible, would prefer to avoid using it: it is pretty heavy-weight, hijacks a lot of my keys, and clutters up my vimruntime with a lot of files. Here is what I have now: if exists('b:tex_build_mapped') finish endif " use maparg or mapcheck to see if key is free command! -buffer -nargs=* BuildTex call BuildTex(0, <f-args>) command! -buffer -nargs=* BuildAndViewTex call BuildTex(1, <f-args>) noremap <buffer> <silent> <F9> <Esc>:call BuildTex(0)<CR> noremap <buffer> <silent> <S-F9> <Esc>:call BuildTex(1)<CR> let b:tex_build_mapped = 1 if exists('g:tex_build_loaded') finish endif let g:tex_build_loaded = 1 function! BuildTex(view_results, ...) write if filereadable("Makefile") " If Makefile is available in current working directory, run 'make' with arguments echo "(using Makefile)" let l:cmd = "!make ".join(a:000, ' ') echo l:cmd execute l:cmd if a:view_results && v:shell_error == 0 call ViewTexResults() endif else let b:tex_flavor = 'pdflatex' compiler tex make % if a:view_results && v:shell_error == 0 call ViewTexResults() endif endif endfunction function! ViewTexResults(...) if a:0 == 0 let l:target = expand("%:p:r") . ".pdf" else let l:target = a:1 endif if has('mac') execute "! open -a Preview ".l:target endif endfunction The problem is that v:shell_error is not set, even if there are compile errors. Any suggestions or insight on how to detect whether a compile was successful or not would be greatly appreciated! Thanks!

  • How can I remove an "ALMOST" Duplicate using LINQ? ( OR SQL? )

    - by Atomiton
    This should be and easy one for the LINQ gurus out there. I'm doing a complex Query using UNIONS and CONTAINSTABLE in my database to return ranked results to my application. I'm getting duplicates in my returned data. This is expected. I'm using CONTAINSTABLE and CONTAINS to get all the results I need. CONTAINSTABLE is ranked by SQL and CONTAINS (which is run only on the Keywords field ) is hard-code-ranked by me. ( Sorry if that doesn't make sense ) Anyway, because the tuples aren't identical ( their rank is different ) a duplicate is returned. I figure the best way to deal with this is use LINQ. I know I'll be using the Distinct() extension method, but do I have to implement the IEqualityComparer interface? I'm a little fuzzy on how to do this. For argument's sake, say my resultset is structured like this class: class Content { ContentID int //KEY Rank int Description String } If I have a List<Content> how would I write the Distinct() method to exclude Rank? Ideally I'd like to keep the Content's highest Rank. SO, if one Content's RAnk is 112 and the other is 76. I'd like to keep the 112 rank. Hopefully I've given enough information.

  • Free tools/libraries to compare tables with filtering for SQL Server 2008 and visualize/sync diffs t

    - by MicMit
    I am building certain GUI in C# for a content manager and looking for the tools or code snippets or open libraries ( code ideally in C# ) which allow me the following : 1. For table A in database X (test ) and table A in database Y (production) and for a simple filter ( e.g. listname = "XYZ" ) I need to show additions/deletions/updates in some way. which might be side-by-side or just html report 2 record added html table with some fields 2 record deleted html table with some fields Considering that this task is very common, I guess, certain components should exist ? Components either return some collections from parameters given for further visualizing or just produce reports mentioned above. 2. I need to push changes for the filter I mentioned in 1 and update table in production database for this filter only ( ie for the particular list approved by content person). Again probably there are certain SQL code generators - components in addition to diffs or standalone. 3. The key thing tools/libraries - should be suitable for integration with the existing application in C#.

  • WPF In-Memory Image Display

    - by Aren B
    Im trying to build an Item Template for my list-view and im bound to a list of Entities. The entity I have has a System.Drawing.Image that I'd like to display, but so far I cannot for the life of me figure out how to bind it to the <Image> block. Every example and documentation I can find on the internet pertains to Images accessible via an uri i.e. File on HDD or On Website <DataTemplate x:Key="LogoPreviewItem"> <Border BorderBrush="Black" BorderThickness="1"> <DockPanel Width="150" Height="100"> <Image> <Image.Source> <!-- {Binding PreviewImage} is where the System.Drawing.Image is in this context --> </Image.Source> </Image> <Label DockPanel.Dock="Bottom" Content="{Binding CustomerName}" /> </DockPanel> </Border> </DataTemplate>

  • What is the 'page lifecycle' of an ASP.NET MVC page, compared to ASP.NET WebForms?

    - by Simon
    What is the 'page lifecycle' of an ASP.NET MVC page, compared to ASP.NET WebForms? I'm tryin to better understand this 'simple' question in order to determine whether or not existing pages I have in a (very) simple site can be easily converted from ASP.NET WebForms. Either a 'conversion' of the process below, or an alternative lifecycle would be what I'm looking for. What I'm currently doing: (yes i know that anyone capable of answering my question already knows all this -- i'm just tryin to get a comparison of the 'lifecycle' so i thought i'd start by filling in what we already all know) Rendering the page: I have a master page which contains my basic template I have content pages that give me named regions from the master page into which I put content. In an event handler for each content page I load data from the database (mostly read-only). I bind this data to ASP.NET controls representing grids, dropdowns or repeaters. This data all 'lives' inside the HTML generated. Some of it gets into ViewState (but I wont go into that too much!) I set properties or bind data to certain items like Image or TextBox controls on the page. The page gets sent to the client rendered as non-reusable HTML. I try to avoid using ViewState other than what the page needs as a minimum. Client side (not using ASP.NET AJAX): I may use JQuery and some nasty tricks to find controls on the page and perform operations on them. If the user selects from a dropdown -- a postback is generated which triggers a C# event in my codebehind. This event may go to the database, but whatever it does a completely newly generated HTML page ends up getting sent back to the client. I may use Page.Session to store key value pairs I need to reuse later So with MVC how does this 'lifecycle' change?

  • A very weird problem with localization (ASP.NET MVC)

    - by Alex
    I'm using Web Developer 2010. I just created a resource file lang.resx with different values in english. Then I created a lang.FR-fr.resx with French equivalents. However after tryingto compile, I get Error 131 Task could not find "AL.exe" using the SdkToolsPath "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools\" or the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v7.0A". Make sure the SdkToolsPath is set and the tool exists in the correct processor specific location under the SdkToolsPath and that the Microsoft Windows SDK is installed This is so weird! If I remove FR-fr part, it will work, but there will be no translation of course. I went to that directory and found out that I don't have al.exe there. I managed to find it in .NET 2 folder, but after copying it didn't help. It throws an exception. I tried to reinstall .NET 4, to install Windows SDK, and it still doesn't work. Maybe I can somehow get this al.exe file?

  • Nhibernat mapping aspnet_Users table

    - by Michael D. Kirkpatrick
    My User table I want to map to aspnet_Users: <class name="User" table="`User`"> <id name="ID" column="ID" type="Int32" unsaved-value="0"> <generator class="native" /> </id> <property name="UserId" column="UserId" type="Guid" not-null="true" /> <property name="FullName" column="FullName" type="String" not-null="true" /> <property name="PhoneNumber" column="PhoneNumber" type="String" not-null="false" /> </class> My aspnet_Users table: <class name="aspnet_Users" table="aspnet_Users"> <id name="ID" column="UserId" type="Guid" /> <property name="UserName" column="UserName" type="string" not-null="false" /> </class> I tried adding one-to-one, one-to-many and many-to-one mappings. The closest I can get is with this error: Object of type 'System.Guid' cannot be converted to type 'System.Int32'. How do I create a 1 way mapping from User to aspnet_User via the UserId column in User? I am only wanting to create a reference so I can extract read-only information, affect sorts, etc. I still need to leave UserId column in User set up like it is now. Maybe a virtual reference keying off of UserId? Is this even possible with Nhibernate? Unfortunately it acts like it only wants to use ID from User to map to aspnet_Users. Changing the table User to have it's primary key be UserId instead of ID is not an option at this point. Any help would be greatly appreciated. Thanks in advance.

  • PHP Loop Over ONLY Different Arrays

    - by Steven
    Hello, I have a single array with several of the same values. And I only want to loop over DIFFERENT values. How could I go about doing this? Example 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO;_86 166-01 001;09;UO;_86 166-01 001;09;UO;_86 166-01 001;09;UO;_86 166-01 001;09;UO;_86 166-01 001;09;UO;_86_97 166-01 001;09;UO;_86_97 166-01 001;09;UO;_86_97 166-01 001;09;UO;_86_97_108 166-01 001;09;UO;_86_97_108 166-01 001;09;UO;_86_97_108_119 166-01 001;09;UO;_86_97_108_119 I have that in a single array, but I only want to loop for the different ones. So it would loop once for nothing, then once for _86, then once for _86_97, then once for _86_97_108, and then once for _86-97_108_119. So only loop for different key values, or would there be a way to count the number of different keys?

  • SQL Server Index cost

    - by yellowstar
    I have read that one of the tradeoffs for adding table indexes in SQL Server is the increased cost of insert/update/delete queries to benefit the performance of select queries. I can conceptually understand what happens in the case of an insert because SQL Server has to write entries into each index matching the new rows, but update and delete are a little more murky to me because I can't quite wrap my head around what the database engine has to do. Let's take DELETE as an example and assume I have the following schema (pardon the pseudo-SQL) TABLE Foo col1 int ,col2 int ,col3 int ,col4 int PRIMARY KEY (col1,col2) INDEX IX_1 col3 INCLUDE col4 Now, if I issue the statement DELETE FROM Foo WHERE col1=12 AND col2 > 34 I understand what the engine must do to update the table (or clustered index if you prefer). The index is set up to make it easy to find the range of rows to be removed and do so. However, at this point it also needs to update IX_1 and the query that I gave it gives no obvious efficient way for the database engine to find the rows to update. Is it forced to do a full index scan at this point? Does the engine read the rows from the clustered index first and generate a smarter internal delete against the index? It might help me to wrap my head around this if I understood better what is going on under the hood, but I guess my real question is this. I have a database that is spending a significant amount of time in delete and I'm trying to figure out what I can do about it. When I display the execution plan for the deletion, it just shows an entry for "Clustered Index Delete" on table Foo which lists in the details section the other indices that need to be updated but I don't get any indication of the relative cost of these other indices. Are they all equal in this case? Is there some way that I can estimate the impact of removing one or more of these indices without having to actually try it?

  • WPF Collapsed Grid not Styling

    So, I have a grid inside a listbox. The purpose is that when the listboxitem is selected, I want the grid to show, having the selected item expand to show more detail information. I set up a style trigger for this and it works great, except for one thing: the labels and textblocks styles are unapplied on the grid. I'm assuming this has something to do with the default state of the listboxitem being collapsed, so wpf skips the styles, I was hoping it would put them on when selected fired, but it doesn't. If I use Style="{StaticResource Mystyle}" on each label/textblock, it styles fine, it just seems to not be doing the inherited style magic like it does with visible grids elsewhere in the app. See code below, the labels don't show up bolded or anything when the grid appears. <Style TargetType="{x:Type Grid}" x:Key="ListBoxItemCollapseGrid"> <Style.Triggers> <DataTrigger Binding="{Binding Path=IsSelected, RelativeSource= { RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem} } }" Value="False"> <Setter Property="Grid.Visibility" Value="Collapsed" /> </DataTrigger> </Style.Triggers> <Style.Resources> <Style TargetType="{x:Type Label}"> <Setter Property="FontWeight" Value="Bold" /> <Setter Property="Foreground" Value="{StaticResource BaseText}" /> <Setter Property="Padding" Value="3,0,0,0" /> </Style> <Style TargetType="{x:Type TextBlock}"> <Setter Property="Foreground" Value="{StaticResource BaseText}" /> </Style> </Style.Resources> </Style>

But I cannot impose IF (room_id IS NOT NULL) THEN since it will create KeyToBin('') and RoomKey is foreign key , KeyToBin('') will produce an invalid RoomKey. Any Idea?

  • inverse relation to multiple inheriting classes in django

    - by Ofri Raviv
    Here are my schematic models: class Law(models.Model): ... class Bill(models.Model): ... # data for a proposed law, or change of an existing law class PrivateBill(Bill): ... # data for a Bill that was initiated by a parliament member class GovernmentBill(Bill): ... # data for a Bill that was initiated by the government It is possible and likely that in the future I (or maybe someone else) would want to add more Bill types. Every Bill should point to a Law (indicating what law this bill is going to change) and my question is: What is the best way to implement this? If I add the ForeignKey(Law) to Bill, I'll have a relation from every Bill to Law, but a Law would only have an inverse relation to Bills (bill_set), and not a different inverse relation to each type of bill. Of course I'll be able to filter each type of bill to get only the ones pointing to a specific Law, but this is something I think I'll need to use often, so I think having privatebill_set, governmentbill_set etc would make the code more readable. Another possible solution is to add the foreign key to each of the inheriting classes (this would give me a privatebill_set, governmentbill_set, futurebill_set), but that seems hairy because I would be relying on future programmers to remember to add that relation. How would you solve this?

  • GLFW - Not drawing square

    - by m00st
    I am using GLFW as GUI for OpenGL projects. I am using my red book and testing code and well the first bit of code doesn't work at all. I want to say this is a GLFW problem because I don't have this problem in JOGL. #include <iostream> #include "GL/glfw.h" #ifndef MAIN #define MAIN #include "GL/gl.h" #include "GL/glu.h" #endif using namespace std; int main() { int running = GL_TRUE; glfwInit(); if( !glfwOpenWindow( 300,300, 0,0,0,0,0,0, GLFW_WINDOW ) ) { glfwTerminate(); return 0; } while( running ) { //GL Code here glClear(GL_COLOR_BUFFER_BIT); glClearColor(0.0, 0.0, 0.0, 0.0); glColor3f(1.0, 1.0, 1.0); glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0); glBegin(GL_POLYGON); glVertex3f(0.25, 0.25, 0.0); glVertex3f(0.75, 0.25, 0.0); glVertex3f(0.75, 0.75, 0.0); glVertex3f(0.25, 0.75, 0.0); glEnd(); glFlush(); glfwSwapBuffers(); // Check if ESC key was pressed or window was closed running = !glfwGetKey( GLFW_KEY_ESC ) && glfwGetWindowParam( GLFW_OPENED ); } glfwTerminate(); return 0; }
