  • Creating a Rails query from a hash of user input

    - by Jamie
    I'm attempting to create a fairly complex search engine for a project using a variable number of search criteria. The user input is sorted into an array of hashes. The hashes contain the following information: { :column => "", :value => "", :operator => "", # Such as: =, !=, <, >, etc. :and_or => "", # Two possible values: "and" and "or" } How can I loop through this array and use the information in these hashes to make an ActiveRecord WHERE query?

  • How do I correct "Commit Failed. File xxx is out of date. xxx path not found."

    - by Ryan Taylor
    I have recently run into a particularly sticky issue regarding committing the result of a merge in subversion. Our Subversion server is @ 1.5.0 and my TortoiseSVN client is now @ 1.6.1. I am trying to merge a feature branch back into my trunk. The merge appears to work okay; however, the commit fails with the following error message. Commit failed (details follow): File 'flex/src/com/penbay/invision/portal/services/http/soap/ReportServices/GetAllBldgsParamsByRegionBySiteResultEvent.as' is out of date '/svn/ibis/!svn/wrk/531d459d-80fa-ea46-bfb4-940d79ee6d2e/visualization/trunk/source/flex/src/com/penbay/invision/portal/services/http/soap/ReportServices/GetAllBldgsParamsByRegionBySiteResultEvent.as' path not found You have to update your working copy first. My working trunk is up to date. I have even checked out a new one into a different folder to make sure there wasn't any local cruft messing with the merge. I have done some more research into this and I think part of the problem is user error. I think our problems are: We had some developers committing work with a subversion client before 1.5 and some after. I believe this has the potential to corrupt the merge info. In other branches we have performed partial merges. That is, we did not always perform merges at the root of the branch. This was to facilitate updating Flex and .NET efforts within the same branch. We performed cyclic (reflexive) merges on our branch. This was done because we had multiple parallel branches and we wanted to periodically update our branch with the latest code in trunk. All of these things are explicitly not recommended by the Subversion book/team. We have learned our lesson and now know the best practices. However, we first need to merge and commit our latest branch. What it the best way to correct the problems we are encountering? Would deleting all the merge info in the trunk and branch be a viable solution? No. I have done this but it does not resolve the error that I am getting above.

  • Jquery Widget Performance

    - by jamie-wilson
    I am working on an interface which involves ALOT of javascript. There is a calendar and blocks drawn on the calendar. The calendar is a jQuery widget, which works beautifully. The blocks drawn on top are also jQuery widgets. While it works - I am wondering, every time I create another block, is the widget fully duplicating, or is it referencing the widget? If I end up with 200 blocks on the screen, do I have 200 copies of the widget? Because if so i'm sure this will impact the performance quite heavily. Also it would determine whether I have functions inside the widget, or have them external to the widget looking in if that makes sense. Just putting some feelers out there for thoughts. I couldn't find anything by searching online.

  • WHy am I unable to add text along with <%# Container.DataItem %> in repeater in user control

    - by Jamie Hartnoll
    I have a User Control which is dynamically placed by CodeBehind as follows: Dim myControl As Control = CType(Page.LoadControl("~/Controls/mainMenu.ascx"), Control) If InStr(Request.ServerVariables("url"), "/Login.aspx") <= 0 Then mainMenu.Controls.Add(myControl) End If As per an example from my previous question on here. Within this Control is a repeater which calls a database to generate values. My Repeater mark-up is as follows <asp:Repeater runat="server" ID="locationRepeater" OnItemDataBound="getQuestionCount"> <ItemTemplate> <p id='locationQuestions' title='<%# Container.DataItem %>' runat='server'></p> </ItemTemplate> </asp:Repeater> The example above works fine, but I want to be able to prepend text to <%# Container.DataItem %> in the title attribute of that <p to print to the browser like this is some text DATA_ITEM_OUTPUT When I try to do that though, it prints this is some text <%# Container.DataItem %> exactly like that, ie, turning <%# Container.DataItem %> into text, NOT the value from the repeater code. It was working fine before I made it into a dynamically inserted control, so I am thinking I might have something being generated in the wrong order, but given that it works without any prepended text, I am stumped to fix it! I'm new to .net and using vb.net, please could someone point me in the right direction?

  • Casting to a struct from LPVOID - C

    - by Jamie Keeling
    Hello, I am writing a simple console application which will allow me to create a number of threads from a set of parameters passed through the arguments I provide. DWORD WINAPI ThreadFunc(LPVOID threadData) { } I am packing them into a struct and passing them as a parameter into the CreateThread method and trying to unpack them by casting them to the same type as my struct from the LPVOID. I'm not sure how to cast it to the struct after getting it through so I can use it in the method itself, i've tried various combinations (Example attatched) but it won't compile. Struct: #define numThreads 1 struct Data { int threads; int delay; int messages; }; Call to method: HANDLE hThread; DWORD threadId; struct Data *tData; tData->threads = numThreads; tData->messages = 3; tData->delay = 1000; // Create child thread hThread = CreateThread( NULL, // lpThreadAttributes (default) 0, // dwStackSize (default) ThreadFunc, // lpStartAddress &tData, // lpParameter 0, // dwCreationFlags &threadId // lpThreadId (returned by function) ); My attempt: DWORD WINAPI ThreadFunc(LPVOID threadData) { struct Data tData = (struct Data)threadData; int msg; for(msg = 0; msg<5; msg++) { printf("Message %d from child\n", msg); } return 0; } Compiler error: error C2440: 'type cast' : cannot convert from 'LPVOID' to 'Data' As you can see I have implemented a way to loop through a number of messages already, I'm trying to make things slightly more advanced and add some further functionality.

  • How can I hide the SiteMapPath root node on home page?

    - by Jamie Ide
    How can I hide the root node in a SiteMapPath control when the user is on the root node page? For example, my breadcrumb trail on a child page is: Home Products Hammers Ball Peen which is fine. But when the user is on the Home page, the SiteMapPath control displays Home which is useless clutter. I want to suppress displaying Home (the root node) when the user is on the home page. I have the SiteMapPath control in a master page. Also, I'm handling SiteMapResolve to set the querystrings in the nodes.

  • jQuery | Click child, hides parent

    - by Jamie
    Hey, I have a list of using ul and li: <span class="important">Show/Hide</span> <div id="important" class="hidden"> <ul class="sub"> <li> Value one </li> <li class="child"> <img src="../img/close.png" /> </li> </ul> </div> $(".important").click(function () { $("#important").slideToggle("fast"); }); When the child (class="child") is clicked on, it should slide up the div (id="important"), however, there are other lists that have different IDs, I want the div to slide up when the child is clicked I did this: $(".child").click(function () { $(".child < div").slideUp("fast"); }); I have no idea how to make it work, I've done other combinations, can't seem to do it.

  • Mixing RewriteRule and ProxyPass in Apache

    - by Taylor L
    I was working on debugging an issue today related to mixing mod_proxy and mod_rewrite together and I ended up having to use balancer://mycluster in the RewriteRule in order to stop receiving a 404 error from Apache. I have two questions: 1) Is there any other way to get the rewritten URL to go through the balancer without adding balancer://mycluster into the RewriteRule? 2) Is there a way to define all the parameters I defined in ProxyPass (stickysession=JSESSIONID|jsessionid scolonpathdelim=On lbmethod=bytraffic nofailover=Off) in either the <Proxy> or RewriteRule? I'm concerned the requests that match the new RewriteRule won't load balance in the same fashion as those that go through ProxyPass (like /app1/something.do)? Below are the relevant sections of the httpd.conf. I am using Apache 2.2. <Proxy balancer://mycluster> Order deny,allow Allow from all BalancerMember ajp://my.domain.com:8009 route=node1 BalancerMember ajp://my.domain.com:8009 route=node2 </Proxy> ProxyPass /app1 balancer://mycluster/app1 stickysession=JSESSIONID|jsessionid scolonpathdelim=On lbmethod=bytraffic nofailover=Off ProxyPassReverse /app1 ajp://my.domain.com:8009/app1 ...

  • How to display a date as iso 8601 format with PHP

    - by Matthew James Taylor
    I'm trying to display a datetime from my MySQL database as an iso 8601 formated string with PHP but it's coming out wrong. 17 Oct 2008 is coming out as: 1969-12-31T18:33:28-06:00 which is clearly not correct (the year should be 2008 not 1969) This is the code I'm using: <?= date("c", $post[3]) ?> $post[3] is the datetime (CURRENT_TIMESTAMP) from my MySQL database. Any ideas what's going wrong?

  • Spring - Redirect after POST (even with validation errors)

    - by Taylor L
    I'm trying to figure out how to "preserve" the BindingResult so it can be used in a subsequent GET via the Spring <form:errors> tag. The reason I want to do this is because of Google App Engine's SSL limitations. I have a form which is displayed via HTTP and the post is to an HTTPS URL. If I only forward rather than redirect then the user would see the https://whatever.appspot.com/my/form URL. I'm trying to avoid this. Any ideas how to approach this? Below is what I'd like to do, but I only see validation errors when I use return "create". @RequestMapping(value = "/submit", method = RequestMethod.POST) public final String submit( @ModelAttribute("register") @Valid final Register register, final BindingResult binding) { if (binding.hasErrors()) { return "redirect:/register/create"; } return "redirect:/register/success"; }

    I have a style defined in a resource dictionary that applies to all ComboBox controls. Within the ComboBox control, I reference the style like so: Style="{DynamicResource MyComboBoxStyle}" This works ok. I want to be able to add some triggers to some of the ComboBox controls. What is a good way to use the style referenced as a dynamic resource yet still be able to add triggers to some of the ComboBox controls?

  • Error using CreateFileMapping - C

    - by Jamie Keeling
    Hello, I am using the tutorial on this MSDN link to implement a way of transferring data from one process to another. Although I was advised in an earlier question to use the Pipe methods, due to certain constraints I have no choice but to use the CreateFileMapping method. Now, i've succesfully managed to make two seperate window form projects within the same solution and by editing some properties both of the forms load at the same time. Furthermore I have managed to implement the code given in the MSDN sample into the first (Producer) and second (Consumer) program without any compilation errors. The problem I am having now is when I run the first program and try to create the handle to the mapped file, I am given an error saying it was unsuccesful and I do not understand why this is happening. I have added both the Producer and Consumer code files to demonstrate what I am trying to do. Producer: #include <windows.h> #include <stdio.h> #include <conio.h> //File header definitions #define IDM_FILE_ROLLDICE 1 #define IDM_FILE_QUIT 2 #define BUF_SIZE 256 TCHAR szName[]=TEXT("Global\\MyFileMappingObject"); TCHAR szMsg[]=TEXT("Message from first process!"); void AddMenus(HWND); LRESULT CALLBACK WindowFunc(HWND, UINT, WPARAM, LPARAM); ////Standard windows stuff - omitted to save space. ////////////////////// // WINDOWS FUNCTION // ////////////////////// LRESULT CALLBACK WindowFunc(HWND hMainWindow, UINT message, WPARAM wParam, LPARAM lParam) { WCHAR buffer[256]; LPCTSTR pBuf; struct DiceData storage; HANDLE hMapFile; switch(message) { case WM_CREATE: { // Create Menus AddMenus(hMainWindow); } break; case WM_COMMAND: // Intercept menu choices switch(LOWORD(wParam)) { case IDM_FILE_ROLLDICE: { //Roll dice and store results in variable //storage = RollDice(); ////Copy results to buffer //swprintf(buffer,255,L"Dice 1: %d, Dice 2: %d",storage.dice1,storage.dice2); ////Show via message box //MessageBox(hMainWindow,buffer,L"Dice Result",MB_OK); hMapFile = CreateFileMapping( (HANDLE)0xFFFFFFFF, // use paging file NULL, // default security PAGE_READWRITE, // read/write access 0, // maximum object size (high-order DWORD) BUF_SIZE, // maximum object size (low-order DWORD) szName); // name of mapping object if (hMapFile == NULL) { MessageBox(hMainWindow,L"Could not create file mapping object",L"Error",NULL); return 1; } pBuf = (LPTSTR) MapViewOfFile(hMapFile, // handle to map object FILE_MAP_ALL_ACCESS, // read/write permission 0, 0, BUF_SIZE); if (pBuf == NULL) { MessageBox(hMainWindow,L"Could not map view of file",L"Error",NULL); CloseHandle(hMapFile); return 1; } CopyMemory((PVOID)pBuf, szMsg, (_tcslen(szMsg) * sizeof(TCHAR))); _getch(); UnmapViewOfFile(pBuf); CloseHandle(hMapFile); } break; case IDM_FILE_QUIT: SendMessage(hMainWindow, WM_CLOSE, 0, 0); break; } break; case WM_DESTROY: PostQuitMessage(0); break; } return DefWindowProc(hMainWindow, message, wParam, lParam); } // //Setup menus // Consumer: #include <windows.h> #include <stdio.h> #include <conio.h> //File header definitions #define IDM_FILE_QUIT 1 #define IDM_FILE_POLL 2 #define BUF_SIZE 256 TCHAR szName[]=TEXT("Global\\MyFileMappingObject"); //Prototypes void AddMenus(HWND); LRESULT CALLBACK WindowFunc(HWND, UINT, WPARAM, LPARAM); //More standard windows creation, again omitted. ////////////////////// // WINDOWS FUNCTION // ////////////////////// LRESULT CALLBACK WindowFunc(HWND hMainWindow, UINT message, WPARAM wParam, LPARAM lParam) { HANDLE hMapFile; LPCTSTR pBuf; switch(message) { case WM_CREATE: { // Create Menus AddMenus(hMainWindow); break; } case WM_COMMAND: { // Intercept menu choices switch(LOWORD(wParam)) { case IDM_FILE_POLL: { hMapFile = OpenFileMapping( FILE_MAP_ALL_ACCESS, // read/write access FALSE, // do not inherit the name szName); // name of mapping object if (hMapFile == NULL) { MessageBox(hMainWindow,L"Could not open file mapping object",L"Error",NULL); return 1; } pBuf = (LPTSTR) MapViewOfFile(hMapFile, // handle to map object FILE_MAP_ALL_ACCESS, // read/write permission 0, 0, BUF_SIZE); if (pBuf == NULL) { MessageBox(hMainWindow,L"Could not map view of file",L"Error",NULL); CloseHandle(hMapFile); return 1; } MessageBox(NULL, pBuf, TEXT("Process2"), MB_OK); UnmapViewOfFile(pBuf); CloseHandle(hMapFile); break; } case IDM_FILE_QUIT: SendMessage(hMainWindow, WM_CLOSE, 0, 0); break; } break; } case WM_DESTROY: { PostQuitMessage(0); break; } } return DefWindowProc(hMainWindow, message, wParam, lParam); } // //Setup menus // It's by no means tidy and final but it's just a start, thanks for any help.

  • How to provide js-ctypes in a spidermonkey embedding?

    - by Triston J. Taylor
    Summary I have looked over the code the SpiderMonkey 'shell' application uses to create the ctypes JavaScript object, but I'm a less-than novice C programmer. Due to the varying levels of insanity emitted by modern build systems, I can't seem to track down the code or command that actually links a program with the desired functionality. method.madness This js-ctypes implementation by The Mozilla Devs is an awesome addition. Since its conception, scripting has been primarily used to exert control over more rigorous and robust applications. The advent of js-ctypes to the SpiderMonkey project, enables JavaScript to stand up and be counted as a full fledged object oriented rapid application development language flying high above 'the bar' set by various venerable application development languages such as Microsoft's VB6. Shall we begin? I built SpiderMonkey with this config: ./configure --enable-ctypes --with-system-nspr followed by successful execution of: make && make install The js shell works fine and a global ctypes javascript object was verified operational in that shell. Working with code taken from the first source listing at How to embed the JavaScript Engine -MDN, I made an attempt to instantiate the JavaScript ctypes object by inserting the following code at line 66: /* Populate the global object with the ctypes object. */ if (!JS_InitCTypesClass(cx, global)) return NULL; /* I compiled with: g++ $(./js-config --cflags --libs) hello.cpp -o hello It compiles with a few warnings: hello.cpp: In function ‘int main(int, const char**)’: hello.cpp:69:16: warning: converting to non-pointer type ‘int’ from NULL [-Wconversion-null] hello.cpp:80:20: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings] hello.cpp:89:17: warning: NULL used in arithmetic [-Wpointer-arith] But when you run the application: ./hello: symbol lookup error: ./hello: undefined symbol: JS_InitCTypesClass Moreover JS_InitCTypesClass is declared extern in 'dist/include/jsapi.h', but the function resides in 'ctypes/CTypes.cpp' which includes its own header 'CTypes.h' and is compiled at some point by some command during 'make' to yeild './CTypes.o'. As I stated earlier, I am less than a novice with the C code, and I really have no idea what to do here. Please give or give direction to a generic example of making the js-ctypes object functional in an embedding.

  • Problem running python/matplotlib in background after ending ssh session.

    - by Jamie
    Hi there, I have to VPN and then ssh from home to my work server and want to run a python script in the background, then log out of the ssh session. My script makes several histogram plots using matplotlib, and as long as I keep the connection open everything is fine, but if I log out I keep getting an error message in the log file I created for the script. File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 2058, in loglog ax = gca() File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 582, in gca ax = gcf().gca(**kwargs) File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 276, in gcf return figure() File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 254, in figure **kwargs) File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/backends/backend_tkagg.py", line 90, in new_figure_manager window = Tk.Tk() File "/Home/eud/jmcohen/.local/lib/python2.5/lib-tk/Tkinter.py", line 1647, in __init__ self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use) _tkinter.TclError: couldn't connect to display "localhost:10.0" I'm assuming that it doesn't know where to create the figures I want since I close my X11 ssh session. If I'm logged in while the script is running I don't see any figures popping up (although that's because I don't have the show() command in my script), and I thought that python uses tkinter to display figures. The way that I'm creating the figures is, loglog() hist(list,x) ylabel('y') xlabel('x') savefig('%s_hist.ps' %source.name) close() The script requires some initial input, so the way I'm running it in the background is python scriptToRun.py << start>& logfile.log& Is there a way around this, or do I just have to stay ssh'd into my machine? Thanks.
