  • Windows Service And Thread Programming .NET

    - by Raghu
    I have developed windows service to process files whose records will be stored in database. When windows service finds a file it creates a thread and assigns each file to one thread. I have not used Thread Pool. I wanted to know when windows service is stopped, then how to identify how many threads are running and whether they are complete. If all the threads are executed then windows service can be stopped successfully. Otherwis windows service should wait until all threads are executed or aborted. How to implement this.

  • combining dynamic text with regular expressions in php

    - by pfunc
    I am experimenting with finding popular keywords using curl, php and regular expressions. I have an array of non-specific nouns that I am matching my keyword search up. So I am looking for words like "the", "and", "that" etc. and taking them out of the keyword search. so I have an array of words like so: $wordArr = [the, and, at,....]; and then running something like: && preg_match('(\bmyword\w*\b)', $key) == false how do I combine these two so it loops through the array finding out if any of the words in the array match the regular expression? I guess I could just do a for loop, but though maybe I could use in_array($wordArr, $key).. or something like that.

  • C socket programming: client send() but server select() doesn't see it

    - by Fantastic Fourier
    Hey all, I have a server and a client running on two different machines where the client send()s but the server doesn't seem to receive the message. The server employs select() to monitor sockets for any incoming connections/messages. I can see that when the server accepts a new connection, it updates the fd_set array but always returns 0 despite the client send() messages. The connection is TCP and the machines are separated by like one router so dropping packets are highly unlikely. I have a feeling that it's not select() but perhaps send()/sendto() from client that may be the problem but I'm not sure how to go about localizing the problem area. while(1) { readset = info->read_set; ready = select(info->max_fd+1, &readset, NULL, NULL, &timeout); } above is the server side code where the server has a thread that runs select() indefinitely. rv = connect(sockfd, (struct sockaddr *) &server_address, sizeof(server_address)); printf("rv = %i\n", rv); if (rv < 0) { printf("MAIN: ERROR connect() %i: %s\n", errno, strerror(errno)); exit(1); } else printf("connected\n"); sleep(3); char * somemsg = "is this working yet?\0"; rv = send(sockfd, somemsg, sizeof(somemsg), NULL); if (rv < 0) printf("MAIN: ERROR send() %i: %s\n", errno, strerror(errno)); printf("MAIN: rv is %i\n", rv); rv = sendto(sockfd, somemsg, sizeof(somemsg), NULL, &server_address, sizeof(server_address)); if (rv < 0) printf("MAIN: ERROR sendto() %i: %s\n", errno, strerror(errno)); printf("MAIN: rv is %i\n", rv); and this is the client side where it connects and sends messages and returns connected MAIN: rv is 4 MAIN: rv is 4 any comments or insightful insights are appreciated.

  • Python meta programming question

    - by orokusaki
    I have a meta class MyClass which adds an attribute to a class based on some of the properties of the class's methods. When I subclass MyClass I want it to still have that attribute, and append to the attribute's value based on the sub-class's methods (ie, sub-classing extends the same attribute that the base's meta creates.). Can this be done via the bases argument passed to __new__(cls, name, bases, dct)?

  • ASP: runat=server for dynamic control

    - by Jan
    In the Page_Load method I create a couple of controls, based on various conditions. I would like to register server side code with those controls. However, for the last part I need to declare my controls as server controls. This is normally done by runat=server, but I don't know how to set this attribute in the C# code. myControl.Attributes.Add("runat", "server") does not do the trick. This one works, meaning that the "test" method is called when I click on it: <asp:LinkButton ID="LinkButton1" runat="server" OnClick="test">testtext</asp:LinkButton> This one does not work: LinkButton lb = new LinkButton(); lb.ID = "LinkButton1"; lb.OnClientClick = "test"; lb.Text = "testtext"; lb.Attributes.Add("runat", "server"); I can click on it, and the page is loaded, but the test-method is not called. Any hints?

  • How do I REALLY get started programming in Ruby on Rails

    - by Nate
    I can't figure out where exactly to go in order to write the Ruby code itself. I know that I can enter things line-by-line in Terminal (I'm on a Mac), but I'd like to figure out how to start using something like Xdrive (Apple won't allow me to download Xrive because I have OS X 10.5, not 10.6). What steps do I need to take in order to start writing code in a program like xDrive. Thank you in advance.

  • Dynamic CSS class names in GWT

    - by Anupam Jain
    I am in the process of porting a simple CSS grid system to GWT. My CSS file currently has classes like .size1, .size2 etc., and I have a CSS resource that looks like - class MyResource extends CSSResource { @ClassName("size1") String size1(); @ClassName("size2") String size2(); // And so on } However what I really want, is to have a single function like the following - String size(int size); which will generate the appropriate class when passed the size as an integer at runtime. This is needed as I perform some calculations to determine the actual space available/needed for a widget in javascript and then attach the appropriate class name. Is this something that is even possible with GWT?

  • Flex dynamic form height

    - by Daryl
    I'm not sure if this is possible, is there a way to get the <mx:Form> to set its own height based on the position of an element within it? For example something like this: <mx:Form height="{submitBtn.y + submitBtn.height}"> <mx:FormItem>... </mx:FormItem> <mx:FormItem>... </mx:FormItem> <mx:FormItem>... </mx:FormItem> <mx:FormItem> <s:Button id="submitBtn" label="Submit" /> </mx:FormItem> </mx:Form> where the form height is dynamically set based on submitBtn's y position and its height. I tried using Alert.show to show these values and turned out submitBtn.y = 0 and submitBtn.height = 21. height sounds reasonable, but I know the submitBtn.y can't be 0 since it's below several other Is it possible to set the form height dynamically?

  • Download dynamic file with GWT

    - by Maksim
    I have a GWT page where user enter data (start date, end date, etc.), then this data goes to the server via RPC call. On the server I want to generate Excel report with POI and let user save that file on their local machine. This is my test code to stream file back to the client but for some reason I think it does not know how to stream file to the client when I'm using RPC: public class ReportsServiceImpl extends RemoteServiceServlet implements ReportsService { public String myMethod(String s) { File f = new File("/excelTestFile.xls"); String filename = f.getName(); int length = 0; try { HttpServletResponse resp = getThreadLocalResponse(); ServletOutputStream op = resp.getOutputStream(); ServletContext context = getServletConfig().getServletContext(); resp.setContentType("application/octet-stream"); resp.setContentLength((int) f.length()); resp.setHeader("Content-Disposition", "attachment; filename*=\"utf-8''" + filename + ""); byte[] bbuf = new byte[1024]; DataInputStream in = new DataInputStream(new FileInputStream(f)); while ((in != null) && ((length = in.read(bbuf)) != -1)) { op.write(bbuf, 0, length); } in.close(); op.flush(); op.close(); } catch (Exception ex) { ex.printStackTrace(); } return "Server says: " + filename; } } I've red somewhere on internet that you can't do file stream with RPC and I have to use Servlet for that. Is there any example of how to use Servlet and how to call that servlet from ReportsServiceImpl. Do I really need to make a servlet or it is possible to stream it back with my RPC?

  • Programming help Loop adding

    - by Deonna
    I know this probably really simple but Im not sure what im doing wrong... The assignment states: For the second program for this lab, you are to have the user enter an integer value in the range of 10 to 50. You are to verify that the user enters a value in that range, and continue to prompt him until he does give you a value in that range. After the user has successfully entered a value in that range, you are to display the sum of all the integers from 1 to the value entered. I have this so far: #include <iostream.h> int main () { int num, sum; cout << "do-while Loop Example 2" << endl << endl; do { cout << "Enter a value from 10 to 50: "; cin >> num; if (num < 10 || num > 50) cout << "Out of range; Please try again..." << endl; } while (num < 10 || num > 50); { int i; int sum = 0; for (num = 1; num <= 50; num ++) sum = sum + num; } cout << endl << "The sum is " << sum << endl; return 0; } Im just not sure exactly what i'm doing wrong... I keep getting the wrong sum for the total...

  • NES Programming - Nametables?

    - by Jeffrey Kern
    Hello everyone, I'm wondering about how the NES displays its graphical muscle. I've researched stuff online and read through it, but I'm wondering about one last thing: Nametables. Basically, from what I've read, each 8x8 block in a NES nametable points to a location in the pattern table, which holds graphic memory. In addition, the nametable also has an attribute table which sets a certain color palette for each 16x16 block. They're linked up together like this: (assuming 16 8x8 blocks) Nametable, with A B C D = pointers to sprite data: ABBB CDCC DDDD DDDD Attribute table, with 1 2 3 = pointers to color palette data, with < referencing value to the left, ^ above, and ' to the left and above: 1<2< ^'^' 3<3< ^'^' So, in the example above, the blocks would be colored as so 1A 1B 2B 2B 1C 1D 2C 2C 3D 3D 3D 3D 3D 3D 3D 3D Now, if I have this on a fixed screen - it works great! Because the NES resolution is 256x240 pixels. Now, how do these tables get adjusted for scrolling? Because Nametable 0 can scroll into Nametable 1, and if you keep scrolling Nametable 0 will wrap around again. That I get. But what I don't get is how to scroll the attribute table wraps around as well. From what I've read online, the 16x16 blocks it assigns attributes for will cause color distortions on the edge tiles of the screen (as seen when you scroll left to right and vice-versa in SMB3). The concern I have is that I understand how to scroll the nametables, but how do you scroll the attribute table? For intsance, if I have a green block on the left side of the screen, moving the screen to right should in theory cause the tiles to the right to be green as well until they move more into frame, to which they'll revert to their normal colors.

  • Dynamic instant theming a la My Yahoo / iGoogle

    - by Alex Neth
    I can think of lots of ways to do this on my own, but I was hoping to find some sort of best practice and have been having trouble finding other's experiences. I want to create easily themed HTML and provide a real-time selector for the user to experiment with themes. I want to do something like the "Change Appearance" tab at http://my.yahoo.com . I'll be using jQuery. jQuery has a "theming" system, but it seems very much focused on jQuery widgets as opposed to the whole site, and also doesn't appear to address the real-time selection aspect (the jQuery page has this functionality, but I don't think it's part of the library.) Maybe there is a jQuery plugin that already does this? Or some sort of css/jQuery framework?

  • JSF dynamic ui:include

    - by Ray
    In my app I have tutor and student as roles of user. And I decide that main page for both will be the same. But menu will be different for tutors and users. I made to .xhtml page tutorMenu.xhtml and student.xhtml. And want in dependecy from role include menu. For whole page I use layout and just in every page change content "content part" in ui:composition. In menu.xhtml <h:body> <ui:composition> <div class="menu_header"> <h2> <h:outputText value="#{msg['menu.title']}" /> </h2> </div> <div class="menu_content"> <?:if test="#{authenticationBean.user.role.roleId eq '2'}"> <ui:include src="/pages/content/body/student/studentMenu.xhtml"/> </?:if> <?:if test= "#{authenticationBean.user.role.roleId eq '1'}"> <ui:include src="/pages/content/body/tutor/tutorMenu.xhtml" /> </?:if> </div> </ui:composition> I know that using jstl my be not better solution but I can't find other. What is the best decision of my problem?

  • Please recommend good books for telemetry / SCADA system design & programming

    - by Mawg
    I am looking at several projects, all with roughly the same fucntionality. Some instruments collect some data (or control some functionality). They commmunicate by Internet (Etehrnet/wifi/GPRS/sasatellite) with a databse server which stores the measurements and provides a browser based means of qeurying the data, prodcuing reports, etc (and possibly also allows control of the remote equipment). Can anyone recommend a good book describing an approach to developing such a software architecture, keeping it generic, which tools, languages. test methods, etc to use? (note to self: ask a similar question about possible existing frameworks)

  • Dynamic Navigation

    - by Dooie
    I am building a project in asp.net 4.0. My navigation will be database driven where i return a datatable from the db containing all the pages of my site, some will be top level while others will be children and sometimes children of children n-times. Im thinking of going down the nested repeater route and databinding from code behind, dynamically generating repeaters for children, but have read that this is not a best practice and should consider the listview control. Im wanting to build a list of links using an unordered list. I cannot find a solid example and was hoping for some pointers/ideas. Thanks Doo
