  • Cannot create class diagram for simple dll class in Visual Studio 2010

    - by xenn_33
    Hi, It seems that there is a really annoying issue in Class Diagram designer in VS (my version is 2010 Ultimate, but the issue is also observed in VS 2008). When I'm trying to create a class diagram for particular simple class from DLL I'm getting the following error: "Some of the selected type(s) cannot be added to the class diagram. Check the code for errors and ensure that all required assemblies ... blah-blah-blah" My code doesn't contain any error. I have multiple class and interface definitions in one separate .cs file, but these classes are really simple - even no calls to unmanaged/interop. Any solution for this?

  • possible to create sql query with table wildcards?

    - by Rees
    this is probably a simple question, but i have been unable to find a solution online, any help would be much appreciated. I'm trying to create an SQL query in PHP and would like to somehow apply a wild card to the TABLE filter... something perhaps like.... select * from %table%. However, I have only so far been able to see filters for column values not table names. as an example i would have tables such as: jan_table_1 feb_table_1 jan_table_2 feb_table_2 and would want to say, select only tables with a "jan" prefix... or "1" suffix. Is there a quick and easy solution to this that I have not seen? Thanks in advance!

  • Floor function returning EXC_BAD_ACCESS

    - by fastrack20
    The cod that I am using contains these snippets of code. I am calling ThetaG_JD with the argument 2455343.50000 which is just a sample Julian date. Every time I run the program, I receive a EXC_BAD_ACCESS on the indicated line. When using gdb and printing out the intermediary values and passing them through the floor function, I get no error, but when Frac() is used it always returns an error. double Frac(double arg) { /* Returns fractional part of double argument */ return arg - floor(arg); } double ThetaG_JD(double jd) { /* Reference: The 1992 Astronomical Almanac, page B6. */ double UT=0, TU=0, GMST=0; //THIS LINE UT=Frac(jd+0.5); // THAT ONE ^^ jd=jd-UT; TU=(jd-2451545.0)/36525; GMST=24110.54841+TU*(8640184.812866+TU*(0.093104-TU*6.2E-6)); GMST=Modulus(GMST+secday*omega_E*UT,secday); return (twopi*GMST/secday); }

  • Django: How to create a model dynamically just for testing

    - by muhuk
    I have a Django app that requires a settings attribute in the form of: RELATED_MODELS = ('appname1.modelname1.attribute1', 'appname1.modelname2.attribute2', 'appname2.modelname3.attribute3', ...) Then hooks their post_save signal to update some other fixed model depending on the attributeN defined. I would like to test this behaviour and tests should work even if this app is the only one in the project (except for its own dependencies, no other wrapper app need to be installed). How can I create and attach/register/activate mock models just for the test database? (or is it possible at all?) Solutions that allow me to use test fixtures would be great.

  • Is there a way to create custom UIDataDetectorTypes?

    - by KingAndrew
    Hi All, What I am trying to do is create tooltip functionality so that certain words in my instructional app can be tapped and the definition pops up. For the popup part I plan on using code from “AFInformationView” which provides bubbles on the iPhone. The part I'm struggling with is how to associate A particular word's location with the bubble. Currently I have the text on a UILabel that is on a custom UITableCell. Since I calculate the row height on the fly with: [textToUse sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:CGSizeMake(stop-start, 500)]; I'm not sure what the coordinates for a specific word will be. I was thinking that if I created a custom DataDetectorType that could be the fix. If anyone knows how to do this or has any other ideas I would be happy to hear them. Thanks, Andrew

  • Python nested function scopes

    - by Thomas O
    I have code like this: def write_postcodes(self): """Write postcodes database. Write data to file pointer. Data is ordered. Initially index pages are written, grouping postcodes by the first three characters, allowing for faster searching.""" status("POSTCODE", "Preparing to sort...", 0, 1) # This function returns the key of x whilst updating the displayed # status of the sort. ctr = 0 def keyfunc(x): ctr += 1 status("POSTCODE", "Sorting postcodes", ctr, len(self.postcodes)) return x sort_res = self.postcodes[:] sort_res.sort(key=keyfunc) But ctr responds with a NameError: Traceback (most recent call last): File "PostcodeWriter.py", line 53, in <module> w.write_postcodes() File "PostcodeWriter.py", line 47, in write_postcodes sort_res.sort(key=keyfunc) File "PostcodeWriter.py", line 43, in keyfunc ctr += 1 UnboundLocalError: local variable 'ctr' referenced before assignment How can I fix this? I thought nester scopes would have allowed me to do this. I've tried with 'global', but it still doesn't work.

  • Edit and Create view using EditCreate.ascx partial in ASP.NET MVC

    - by mare
    If you look at the NerdDinner example of creating and editing dinners then you see they use a partial (ViewUserControl or ASCX) DinnerForm to put the functionality of creating and editing dinners into one file because it is essential the same and they use it using RenderPartial("DinnerForm"). This approach seems fine for me but I've run into a problem where you have to add additonal route values or html properties to the Form tag. This picks up the current action and controller automatically: <% using (Html.BeginForm()) { %> However, if I use another BeginForm() overload which allows to pass in enctype or any other attribute I have to do it like this: <% using ("Create", "Section", new { modal = true }, FormMethod.Post, new { enctype = "multipart/form-data" })) and as you can see we lose the ability to automatically detect in which View we are calling RenderPartial("OurCreateEditFormPartial"). We can't have hardcoded values in there because in Edit View this postback will fail or won't postback to the right controller action. What should I do in this case?

  • How can I create a MethodInfo from an Action delegate

    - by Michael Meadows
    I am trying to develop an NUnit addin that dynamically adds test methods to a suite from an object that contains a list of Action delegates. The problem is that NUnit appears to be leaning heavily on reflection to get the job done. Consequently, it looks like there's no simple way to add my Actions directly to the suite. I must, instead, add MethodInfo objects. This would normally work, but the Action delegates are anonymous, so I would have to build the types and methods to accomplish this. I need to find an easier way to do this, without resorting to using Emit. Does anyone know how to easily create MethodInfo instances from Action delegates?

  • Create an autocompleter like the Facebook status update

    - by Terw
    Hello I'm trying to create a div with contenteditable like the Facebook status update. Then I mean I want to show an autocomplete box when the user have written @. How would you do that. Currently I'm just playing with keypress and check if the keycode = 64. Somehow that works, but it doesn't validate if there's a space before the alfa, or if the user has unfocused the box, then focused it again. Any ideas? Or do you know about any plugin that works something like that? Tnx

  • How to create a VS2010 extension that uses Language Services

    - by Hades32
    Creating extensions got much easier with Vs2010, but this seems not to be the case for everything... My aim: I wnat to make method calls and property uses of STATIC classes ITALIC. (Just like Eclipse and Java) I think I need to talk to the C# Language Service for this information, but searching for "Language Service" just yields results on how to CREATE one, not how to use one of the existing ones... To get this question a little more general: How do I get information about properties of the code (static/visibility etc) for using it in a VSX?

  • language to create flowcharts

    - by robintw
    Hi, This seems like something which must have been answered before, but I can't find anything appropriate in the question archives. Basically, I'm looking for a little Domain Specific Language to create flowcharts. I'm terrible at graphic design and making things look nice, and I'd really like a langauge where I could write something in code and it would produce a pretty flowchart. I've come across GraphViz, but it seems more suited to creating things like Finite State Machine diagrams, rather than process flowcharts. It also doesn't have the simple DSL-style front-end that would allow me to easily work it. Any ideas? I'm sure this must have been done before... Robin

  • How to create a delayed queue in RabbitMQ?

    - by eandersson
    What is the easiest way to create a delay (or parking) queue with Python, Pika and RabbitMQ? I have seen an similar questions, but none for Python. I find this an useful idea when designing applications, as it allows us to throttle messages that needs to be re-queued again. There are always the possibility that you will receive more messages than you can handle, maybe the HTTP server is slow, or the database is under too much stress. I also found it very useful when something went wrong in scenarios where there is a zero tolerance to losing messages, and while re-queuing messages that could not be handled may solve that. It can also cause problems where the message will be queued over and over again. Potentially causing performance issues, and log spam.

  • create a list of threads in C

    - by Hristo
    My implementation (in C) isn't working... the first node is always NULL so I can't free the memory. I'm doing: thread_node_t *thread_list_head = NULL; // done in the beginning of the program ... // later on in the program thread_node_t *thread = (thread_node_t*) malloc(sizeof(thread_node_t)); pthread_create(&(thread->thread), NULL, client_thread, &csFD); thread->next = thread_list_head; thread_list_head = thread; So when I try to free this memory, thread_list_head is NULL. while (thread_list_head != NULL) { thread_node_t *temp = thread_list_head; thread_list_head = thread_list_head->next; free(temp); temp = NULL; } Any advice on how to fix this or just a new way to create this list that would work better? Thanks, Hristo

  • Lack of IsNumeric function in C#

    - by Michael Kniskern
    One thing that has bothered me about C# since its release was the lack of a generic IsNumeric function. I know it is difficult to generate a one-stop solution to detrmine if a value is numeric. I have used the following solution in the past, but it is not the best practice because I am generating an exception to determine if the value is IsNumeric: public bool IsNumeric(string input) { try { int.Parse(input); return true; } catch { return false; } } Is this still the best way to approach this problem or is there a more efficient way to determine if a value is numeric in C#?

  • Create spring beans, based on a comma-separated list of classes

    - by Jeroen
    Is there a way in Spring to create a collection, or array, of beans, based on a comma-separated list of classes. For example: package mypackage; public class Bla { private Set<MyBean> beans; public void setBeans(Set<MyBean> beans) { this.beans = beans; } } With the application context: <bean id="bla" class="mypackage.Bla"> <property name="beans"> <set> <bean class="mypackage.Bean1, mypackage.Bean2" /> </set> </property> </bean> Preferably the beans are all initialized and wired from the context, leaving the code as simplistic as possible, is this possible?

  • Create list in existing site collection from a feature

    - by keysersoze
    I have created a feature, a publishing site, in Visual Studio to MOSS - this feature contains a masterpage, some page-templates, some site columns (grouped to match each page-template) and som custom list templates etc. I have also created a site collection, some sites and pages based on my feature. Now I have upgraded the code in my feature - I wanted a ListInstance to be created based on my custom list template. When I have upgraded my SharePoint (using WSPBuilder), the ListInstance and default data are visible if I create a new site collection, but existing site collection does not get the ListInstance and data. Is there anything I can do to update existing site collections to contain the ListInstance when upgrading?

  • Procedure or function expects parameter which was not supplied

    - by eftpotrm
    Driving me mad on a personal project; I know I've done this before but elsewhere and don't have the code. As far as I can see, I'm setting the parameter, I'm setting its value, the connection is open, yet when I try to fill the dataset I get the error 'Procedure or function expects parameter "@test" which was not supplied'. (This is obviously a simplified test! Same error on this or the real, rather longer code though.) C#: SqlCommand l_oCmd; DataSet l_oPage = new DataSet(); l_oCmd = new SqlCommand("usp_test", g_oConn); l_oCmd.Parameters.Add(new SqlParameter("@test", SqlDbType.NVarChar)); l_oCmd.Parameters[0].Value = "hello world"; SqlDataAdapter da = new SqlDataAdapter(l_oCmd); da.Fill(l_oPage); SQL: create procedure usp_test ( @test nvarchar(1000) ) as select @test What have I missed?

  • How can I check if a particular jQuery UI function is available and use a different function if it i

    - by Mark B
    I'm writing a jQuery plugin and I would like my code to take advantage of the jQuery UI show(effect, [options], [speed], [callback]) and hide(effect, [options], [speed], [callback]) functions, which allow you to show and hide elements with a nice animation. However, I'd also like my plugin to degrade gracefully if jQuery UI isn't available, switching back to use the basic, non-animating show() and hide() functions present in the standard jQuery API. I'll need to test for the show and hide functions specifically, as even if jQuery UI is available it could potentially be a custom version, without the Effects components included. At first I thought that I might be able to do something like: if(typeof myelement.show('blind', 'slow') == 'undefined') { myelement.show('blind', 'slow'); } else { myelement.show(); } But of course this doesn't work, as even if UI isn't present, show() is still a function, it just has a different signature—so typeof returns object in either case. So, what's the best way for me to check if jQuery UI is available to my plugin? Any help is much appreciated!

  • PHP equivalent to Perl format function

I remember easily doing this in perl with something like: format BILLFORMAT = Name: @>>>>>>>>>>>>>>>>>>>>>> Age: @### $name, $age . write; Any ideas would be much appreciated, banging my head on the wall with this one.

  • Ruby Built In Method to Create Multidimensional Array From Single Dimensioned Array

    - by Ell
    If I have an array like this: [0, 1, 2, 3, 4, 5], is there a built in method to create this: [[0, 1, 2], [3, 4, 5]] given a width of 3? If there is no built in method, how could I improve on this? def multi_to_single(array, width) return [].tap{|md_array| (array.length.to_f / width).ceil.times {|y| row = (array[(y*width), width]) md_array.push( row + Array.new(width - row.length)) } } end I feel like I have missed something obvious because I haven't programmed ruby in a while! Thanks in advance, ell. EDIT: It needs to be in the core library, so no ruby on rails or anything.

  • How to register a function in a driver code as its ISR

    - by CVS-2600Hertz-wordpress-com
    Following the feedback i got from: http://stackoverflow.com/questions/2683682/new-to-linux-kernel-driver-development/2683819 I have written a driver (.c file) by comparing it with an existing driver and "borrowing" heavily from its code. The driver is registered fine and init() and probe() are working fine. I am also able to access the peripheral device registers. :-) However i am a bit hazy about the IRQ/ISR. The peripheral-device is a input device and raises an interrupt on a GPIO pin. How do i move ahead from my current state ( init(), probe(), etc. ) to be able to handle the IRQ and execute my ISR function?? Many-Thanks in Advance
