• Issues with format in reporting services

  - by Greg Lorenz

  In a report a have a cell that contains a System.Decimal type value. I am using the cells format property to format the value to "D2". This works in VS but not when I run the report on the report server or in my application. If I switch the format string to "0.00" then it works. The confusing part is that it seems that sometimes it works and sometimes it doesn't. Does anyone have any viable explaination for this? I'm not particularly confortable with saying "sometimes it works and sometimes it doesn't"! Is this something that might happen when you have a report written in VS2005 but is running using sql server 2008. I ask because I noticed that when we run the report in our application which is using sql server 2005 it works fine but when we run it against the application where the report is VS2005 and the sql server is 2008 that is where the issue occurs. Thanks.

• GVim highlighting with matchadd eventually slows down?

  - by Kyle MacFarlane

  I have the following in ~/.vim/ftplugin/python.vim to highlight long lines, accidental tabs and extra whitespace in Python files: hi CustomPythonErrors ctermbg=red ctermfg=white guibg=#592929 au BufWinEnter *.py call matchadd('CustomPythonErrors', '\%>80v.\+', -1) au BufWinEnter *.py call matchadd('CustomPythonErrors', '/^\t\+/', -1) au BufWinEnter *.py call matchadd('CustomPythonErrors', '\s\+$', -1) au BufWinLeave *.py call clearmatches() The BufWinLeave is so that the matches are cleared when I switch to another file in case that file isn't a .py file. It's an essential feature for me when working with something like Django. It all works fine for random amounts of time; from ten minutes to hours (my guess is it depends on how many files I open/close). But eventually when any line over 80 characters is displayed GVim slows to a halt and requires a restart. Does anyone have any ideas why this would eventually slow down?

• Basic Client-Server Design for persistent connections?

  - by cam

  Here's as far as I understand it: Client & Server make connection Client sends server data Server interprets data, sends client data So on, and so forth, until client sends disconnect signal. I'm just wondering about implementation. Step 2 and 3 are confusing to me, maybe I'm over-complicating it. Is there anymore to interpreting the data than a giant switch statement? Any good books on client/server design? Specifically talking about multithreaded servers, scalability, and message design (byte 1 = header info, byte 2 = blah blah, etc)? Specifically geared towards C++.

• Vim: multi-file editing - having different makes in different splits

  - by gmatt

  I'm a recent vim convert (from fancy IDEs like eclipse.) I love the :make command in vim and use it extensively; however I also like to edit multiple projects (with separate makefiles.) So usually to edit more than one project I will do pushd project1 vim project1.cpp [suspend signal] pushd ../project2 vim project2.cpp and now I can switch between the two projects with ctrl+z i.e. suspend signal, and fg. When this becomes an issue is when I want to open one project in the context of another so I can do copy/pasting. So if instead in the above I do pushd project1 vim project1.cpp :vsp ../project2/project2.cpp I can edit both concurrently in the same vim process, however I can't effectively build one or the other with the :make command, it will only build project 1. Does anyone have some kind of scheme that gives them the best of both worlds: being able to edit concurrently while still being able to build multiple projects with the :make command all from the same vim process?

• creating an options menu with quit application function

  - by Domen Tomažin

  Hello, I'm writing an application for android and I would like to insert an options menu, that would have only one function and that is to quit an application. My options_menu.xml looks like this (I created a new folder under res called menu - just like the instructions said): Than I added the following code to my java class file: @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.options_menu, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle item selection switch (item.getItemId()) { case R.id.quit: finish(); return true; default: return super.onOptionsItemSelected(item); } I also defined the @string/quit in values - strings.xml file, but it still says that there is an error: C:\Users\Domen\workspace\Lovne Dobe1.1\res\menu\options_menu.xml:3: error: Error: No resource found that matches the given name (at 'title' with value '@string/quit') So if anybody can help I would be very grateful.

• Simple Emacs keybindings

  - by User1

  I have two operations that I do all the time in Emacs: Create a new buffer and paste the clipboard. [C-S-n] Close the current buffer. [C-S-w] Switch to the last viewed buffer [C-TAB] I feel like a keyboard acrobat when doing the first two operations. I think it would be worth trying some custom keybindings and macros. A few questions about this customization: How would I make a macro for #1? Are these good keybindings (i know this is a bit subjective, but they might be used by something popular that I don't use) Has anyone found a Ctrl-Tab macro that will act like Alt-Tab in Linux/Windows? Specifically, I want it have a stack of buffers according to the last viewed timestamp (most recent on top). I want to continue cycling through the stack until I let go of the ctrl key. When the ctrl key is released, I want the current buffer to get an updated position on the stack.

• Django paging object has issues with Postgresql QuerySets

  - by pivotal

  I have some django code that runs fine on a SQLite database or on a MySQL database, but it runs into problems with Postgres, and it's making me crazy that no one has has this issue before. I think it may also be related to the way querysets are evaluated by the pager. In a view I have: def index(request, page=1): latest_posts = Post.objects.all().order_by('-pub_date') paginator = Paginator(latest_posts, 5) try: posts = paginator.page(page) except (EmptyPage, InvalidPage): posts = paginator.page(paginator.num_pages) return render_to_response('blog/index.html', {'posts' : posts}) And inside the template: {% for post in posts.object_list %} {# some rendering jazz #} {% endfor %} This works fine with SQLite, but Postgres gives me: Caught TypeError while rendering: 'NoneType' object is not callable To further complicate things, when I switch the Queryset call to: latest_posts = Post.objects.all() Everything works great. I've tried re-reading the documentation, but found nothing, although I admit I'm a bit clouded by frustration at this point. What am I missing? Thanks in advance.

• How can I refactor that code ? (state pattern ?)

  - by alex

  Hello guys, How can I refactor that code ? public enum enum1 { value1 = 0x01, value2 = 0x02, value3 = 0x03, value4 = 0x04, value5 = 0x05, UNKNOWN = 0xFF } class class1 { private const string STR_VALUE1 = "some text description of value1"; private const string STR_VALUE2 = "some text description of value2"; private const string STR_VALUE3 = "some text description of value3"; private const string STR_VALUE4 = "some text description of value4"; private const string STR_VALUE5 = "some text description of value5"; private const string STR_VALUE6 = "some text description of unknown type"; public static string GetStringByTypeCode(enum1 type) { switch(type) { case enum1.value1: return STR_VALUE1; case enum1.value2: return STR_VALUE2; case enum1.value3: return STR_VALUE3; case enum1.value4: return STR_VALUE4; case enum1.value5: return STR_VALUE5; default: return STR_VALUE6; } } } PS: there are many enum1...enumX and GetStringByTypeCode(enum1) ... GetStringByTypeCode(enumX) methods.

• Project. Properties.Settings versus plain old appSettings?

  - by BryanG

  I have an assembly built that uses appSettings in the app.config...pretty straight forward. however, I'm referencing this assembly in a web service, and that web service contains the nAnt build file for this service plus being the entry point for everything. Ideally I'd like to be able to set the assembly's appConfig values from the build file, but is this possible? Or do I have to switch to using the Settings values of the assembly and do something like this in the build: <xmlpoke file="${PublishLocation}\web.config" xpath="//applicationSettings/Namespace.AssemblyClass.Properties.Settings/setting[@name='ExchangeServer']/value" value="${ServerName}" /> You get the idea. Is this possible with just a config? My ideal situation would be to keep the settings more flexible in the appConfig so that when everything is on the server, if frogs rain down, I can update the assembly's config values without rebuilding the solution. Is this even possible (the xpath is wrong, it's just an example of what I'd like to do): <xmlpoke file="${PublishLocation}\web.config" xpath="//appSettings/Namespace/AssemblyClass/add[@key = 'ExchangeServer']/@value" value="${a}" />

• How can I change what happens when "enter" key is pressed on a DataGridView?

  - by SO give me back my rep

  when I am editing a cell and press enter the next row is automatically selected, I want to stay with the current row... I want to happen nothing except the EndEdit. I have this: private void dtgProductos_CellEndEdit(object sender, DataGridViewCellEventArgs e) { dtgProductos[e.ColumnIndex, e.RowIndex].Selected = true; //this line is not working var index = dtgProductos.SelectedRows[0].Cells.IndexOf(dtgProductos.SelectedRows[0].Cells[e.ColumnIndex]); switch (index) { case 2: { dtgProductos.SelectedRows[0].Cells[4].Selected = true; dtgProductos.BeginEdit(true); } break; case 4: { dtgProductos.SelectedRows[0].Cells[5].Selected = true; dtgProductos.BeginEdit(true); } break; case 5: { btnAddProduct.Focus(); } break; default: break; } } so when I edit a row that is not the last one I get this error: Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.

• How do I create a view with a picker on the bottom and a table view on the top?

  - by Andy

  Hi - first time asker, long-time lurker. I am trying to create an iPhone view that has a date/time picker on the bottom half of the screen, and a grouped, single-section, four-row table view on the top half of the screen (almost identical to the one Apple shows in Fig. 2-4 of their View Controller Programming Guide (but then never goes on to explain). Conceptually, I think I understand that what I need is a main view with a pair of subviews - one for the picker, and one for the table view. I'm pretty sure I can make the picker function once I have it on-screen, and I'm pretty sure I can make the table view function too. What I can't for the life of me figure out is how, programmatically speaking, to get the two views onto the screen simultaneously. I can lay it out perfectly in Interface Builder, but then it all goes to hell when I switch to Xcode...the view appears with the picker, but no table view. Thanks, in advance, for any help you can offer.

• Chrome SSL Security Issue under Windows systems?

  - by fraido

  The Fortify.net website allows you to check what SSL Encryption key is used by your browser. I gave it a try with the browsers I've on my machine and these are the results Fedora 9 Firefox 3.0.8 = AES cipher, 256-bit key Chrome 4.0.249.30 = AES cipher, 256-bit key Windows XP SP3 IE 6.0.2x = RC4 cipher, 128-bit key Firefox = AES cipher, 256-bit key Chrome 4.1.249.1042 (42199) = RC4 cipher, 128-bit key .... WHAT!!?!! Chrome is using RC4 128-bit (as IE6 does) that is well known as been very weak! Chrome under Unix works fine... I'm wondering how is this possible? Do you have this issue or is there a way to change the default key to be AES 256bit? I'm using Chrome as the main browser under Windows and I'm really considering to switch back to Firefox

• Ignoring generated files when using "Treat warnings as errors"

  - by krystan honour

  We have started a new project but also have this problem for an existing project. The problem is that when we compile with a warning level of 4 we also want to switch on 'Treat all warnings as errors' We are unable to do this at the moment because generated files (in particular reference.cs files) are missing things like XML comments and this generates a warning, we do not want to suppress the xml comment warnings totally out of all files just for specific types of files (namely generated code). I have thought of a way this could be achieved but am not sure if these are the best way to do this or indeed where to start :) My thinking is that we need to do something with T4 templates for the code that is generated such that it does fill in XML documentation for generated code. Does anyone have any ideas, currently I'm at well over 2k warnings (its a big project) :(

• @Resource annotated member not injected - bad code or bug?

  - by Brabster

  I am using an @Resource annotation in a class instantiated in a ServletContextListener's contextInitialized(...) method, but the member is always null. Here's my sample code. Listener: public void contextInitialized(ServletContextEvent sce) { System.err.println("In contextInitialised"); new ResourceListenerTargetTest().executeMe(); } ResourceListenerTargetTest: @Resource(name="MyJDBCResource") private DataSource source; public void executeMe() { /*try { InitialContext ictx = new InitialContext(); source = (DataSource)ictx.lookup("java:comp/env/MyJDBCResource"); } catch (NamingException e) { e.printStackTrace(); }*/ System.err.println("source is " + source); } If I switch the comments and run the manual resource lookup, it works fine. Should the @Resource annotation work like this, when used in a contextInitalized method? Appserver is WAS 7.0.0.5, if it should work then I guess it's a bug? Can anyone confirm?

• Can I prevent iPhone from using 3G under any circumstances?

  - by dageshi

  I'm writing a travel guide related app that will download large databases (60meg) potentially overseas, with the reachability code I can tell when a host is reachable via wifi or 3g BUT I'm worried that if for some reason the wifi connection breaks for a minute or so as some DSL connections are likely to do on occasion the iphone will switch transparently to 3G and without realising I could be racking up someones phone bill with overseas data charges! So I'm wondering if anyone has any experience, in the event of such break in wifi connectivity (wifi still works but it's connection to the net is down) would the reachability code report ReachableViaWWAN? So I could wait till my download code returns, check how the host is currently reachable and if it's via 3g I could abort? Is it possible to select what type of connection I can use aka 3g or wifi exclusively?

• JSF: attach rich:toggleControl to radio buttons or select items.

  - by arw

  Has anyone had any success attaching a rich:toggleControl component to a radio button component (h:selectOneRadio) or alternatively any of its children select items (in this case s:enumItem). Basic code example: <h:selectOneRadio value="#{backingValue}"> <s:enumItem enumValue="VAL_1" itemLabel="Value One" /> <s:enumItem enumValue="VAL_2" itemLabel="Value Two" /> <s:convertEnum /> </h:selectOneRadio> The ideal thing would be to attach the toggle control to the enumItems so I could have it switch to a particular state. However at this point I'd be happy if the toggle control can just be attached to the selectOneRadio. I've tried the toggle control as a child of the selectOneRadio and enumItems; neither works. I've also tried wrapping the toggleControl around the selectOneRadio, the toggle control works in this case but the radio buttons don't :(

• How to push text from one UITextfield to another UITextfield in the next View? And back!?

  - by Chrizzz

  an Hi, I have an UITextField in one view, UITextField A in View A. And I have another in view B, UITextField B in View B. I use a Navigation Controller Bar to switch between the views. The UITextFields are properties and connected Outlets of both views A and B. On my view A there is an "Options"-button which pushes view B. So when you are typing in Textfield A, I would like the same text to appear in Textfield B. When you edit TextField B and you go back to view A (via the "Title View A"-button in de navigation bar), I would like the same text to re-appear in Textfield A. I expected this to be easy. But I can't get it working. I tried: ViewBController *controller = [[ViewBController alloc] initWithNibName:@"ViewBController" bundle:nil]; controller.TextFieldA.text = TextFieldB.text But nothing appeared in view B. And how do I get back? I dont want to use NSUserdefaults because I would have to remove the values also.

• Why are the interpreters of all popular scripting languages written in C (if not in C at least not i

  - by wndsr

  I recently asked a question on switching from C++ to C for writing an interpreter for speed and I got a comment from someone asking why on earth I would switch to C for that. So I found out that I actually don't know why - except that C++ object oriented system has a much higher abstraction and therefore is slower. Why are the interpreters of all popular scripting languages written in C and not in C++? If you want to tell me about some other language where the interpreter for it isn't in C, please replace all occurences of popular scripting languages in this question with Ruby, Python, Perl and PHP.

• Texture repeats even with GL_CLAMP_TO_EDGE set

  - by Lliane

  Hi, i'm trying to put a translucing texture on a face which uses points 1 to 4 (don't mind the numbers) on the following screenshot Sadly as you can see the texture repeats herself in both dimensions, I tried to switch the TEXTURE_WRAP_S from REPEAT to CLAMP_to_EDGE but it doesn't change anything. Texture loading code is here : gl.glBindTexture(gl.GL_TEXTURE_2D, mTexture.get(4)); gl.glActiveTexture(4); gl.glTexParameterf(gl.GL_TEXTURE_2D, gl.GL_TEXTURE_MIN_FILTER, gl.GL_LINEAR); gl.glTexParameterf(gl.GL_TEXTURE_2D, gl.GL_TEXTURE_MAG_FILTER, gl.GL_LINEAR); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); gl.glTexImage2D(gl.GL_TEXTURE_2D, 0, gl.GL_RGBA, shadowbmp.width, shadowbmp.height, 0, gl.GL_RGBA, gl.GL_UNSIGNED_SHORT_4_4_4_4, shadowbmp.buffer); Texture coordinates are the following : float shadow_bot_text[] = { 0.0f, 0.0f, 0.0f, 1.0f, 1.0f, 0.0f, 1.0f, 1.0f }; Thanks

• Maintaining a common set of Eclipse preferences

  - by Robert Munteanu

  Whenever I switch workspaces/Eclipse installs I need to copy/redo the preferences: compiler settings; font sizes/families; code formatter; java code templates; editor templates; code clean-ups; I would like to maintain these settings in an unitary way, preferrably under source control. How can I do that? I know about 'copy settings' when creating a new workspace, but it does not keep updated copies.

• Does .NET have a linker?

  - by Water Cooler v2

  From Jon Skeet's blog: What does the following comment mean? // The line below only works when linked rather than // referenced, as otherwise you need a cast. // The compiler treats it as if it both takes and // returns a dynamic value. string value = com.MakeMeDynamic(10); I understand what referencing an assembly is. You may reference it when compiling the program files either using the /ref: switch at the command line or you may add a statically reference to the assembly in Visual Studio. But how do you link to an assembly in .NET? Does he mean, load the assembly using Reflection (Assembly.LoadFile())? Or, the Win32 API LoadLibrary()? Or, does .NET have a linker that I have never heard of?

• How can I extract and save values from an XML file in Perl?

  - by Freddy

  Here is what I am trying to do in a Perl script: $data=""; sub loadXMLConfig() { $filename="somexml.xml" $data = $xml-XMLin($filename); } sub GetVariable() { ($FriendlyName) = @_; switch($FriendlyName) { case "My Friendly Name" {print $data-{my_xml_tag_name}} .... .... .... } } The problem is I am using Perl just because I am reading from an XML file, but I need to get these variables by a shell script. So, here is what I am using: $ perl -e 'require "scrpt.pl"; loadConfigFile(); GetVariable("My Variable")' This works exactly as expected, but I need to read the XML file every time I am getting a variable. Is there a way I could "preserve" $data across shell calls? The idea is that I read the XML file only once. If no, is there is a more simple way I could do this? These are the things I can't change: Config File is an XML Need the variables in a shell script

Should I checkout repository-place all files in trunk folder-add them-commit them-then create tag for current trunk state-create branche for my goal I'm tring to achive-switch to created branch and work there? By the way my repo is local and whole work too. I thank everyone for help.
