  • Find height of ContextMenuStrip before showing it

    - by Nailuj
    I have a ContextMenuStrip (ctMenuMassEdit) that I want to display when left-clicking a button (btnMassEdit). I want the ContextMenuStrip to be displayed above the button, i.e. position (0,-ContextMenuStrip.Height) relative to the button: private void btnMassEdit_Click(object sender, EventArgs e) { ctMenuMassEdit.Show(btnMassEdit, new Point(0, -ctMenuMassEdit.Height)); } However, the Height property is 0 the first time the button is clicked (I assume the ContextMenuStrip isn't created before it is shown the first time), and the result is that the ContextMenuStrip appears on top of the button. The 2nd time I click the button however, it appears in the correct position, so the basic of my logic is at least correct. I tried adding the following before showing the ContextMenuStrip, but it didn't work as hoped: if (!ctMenuMassEdit.Created) { ctMenuMassEdit.CreateControl(); } So, is there a way I can create the ContextMenuStrip before showing it the first time, so I have the correct Height property? I could of course use the hack of showing it, hiding it and showing it again, but that doesn't seem really neat...

  • Pool Billiard AI

    - by Sebi
    Im implementing a pool billiard game in Java and it all works fine. It is a multiplayer game, but nevertheless, it should also be possible to play it alone. For this purpose I'm trying to implement a simple KI. At the moment, the KI choose just randomly a direction and a random intensity of the impulse (don't know the correct english word for that). Of course this AI is very poor and unlikely to ever challenge a player. So i thought about improving the KI, but there are several hard to solve problems. First I thought of just choosing the nearest ball and to try to put it directly into the nearest hole. This isn't that bad, but if there other balls in the line between, it isn't really working anymore. Additionally this dosn't solve te problem of calculating the intensity of the impulse. So are there any general advice? Or any ideas? Best practices?

  • What's the cleanest way to programmatically kill and restart explorer.exe?

    - by Paul Accisano
    Greetings all, I'm working on a Windows program whose installation necessitates restarting explorer.exe. I know "Reboot your computer to complete the installation" is the standard method here, but I'd like my installer to give users the option of just restarting Explorer so they can start using my program immediately. What's the best way to do that? Of course I could just find and kill the process, but that seems rather icky. Is there some trick to, say, make Explorer think the user is logging off and close cleanly? Thanks!

  • Pattern matching in Perl ala Haskell

    - by Paul Nathan
    In Haskell (F#, Ocaml, and others), I can do this: sign x | x > 0 = 1 | x == 0 = 0 | x < 0 = -1 Which calculates the sign of a given integer. This can concisely express certain logic flows; I've encountered one of these flows in Perl. Right now what I am doing is sub frobnicator { my $frob = shift; return "foo" if $frob eq "Foomaticator"; return "bar" if $frob eq "Barmaticator"; croak("Unable to frob legit value: $frob received"); } Which feels inexpressive and ugly. This code has to run on Perl 5.8.8, but of course I am interested in more modern techniques as well.

  • In CAB is a service it's own module?

    - by David Anderson
    I'm learning Composite Application Block and I've hit a rock about services. I have my shell application in its own solution, and of course a test module in its own solution (developed and testing completely independent and external of the shell solution). If I created a service named "Sql Service", would I need to put this in it's own library, so that both the shell, and the module know the types? If that's the case, then for good practice, should I put the service project in the shell solution, or external just like a module (in it's own solution), even though it's not loaded as a module? Then, what about references? Should the shell reference this directly, add then add the service? Or load it as a module and add the service? I have a lot of confusion on where I should create my services, and if I should reference or load as modules..

  • Python (windows) will open files from command line, but not from a script launched from eclipse

    - by Blake
    I'm pretty new to writing python for windows (linux is no problem), and am having problems getting python to recognize files when running scripts, though it behaves fine in the command line What am I doing wrong here? def verifyFile(x): # return os.path.isfile(x) This will return true (with a valid file, of course) when called from the python command line, but when I run the script from eclipse, or launch it from windows, it ALWAYS returns false. Any thoughts on why this is? I've tried passing pathnames like this: D:\Documents and Settings\BDE\Desktop\cdburn.jpg and like this: D:/Documents and Settings/BDE/Desktop/cdburn.jpg I've changed sys,argv[0] to '' I've tried this: def verifyFile(x): # try: f = open(x, 'r') f.close() return True except: return False and am getting no love! Any help would be appreciated. Thanks Blake

  • Drupal Custom Form with Filters

    - by dallasclark
    I'm displaying cars on a page created with a view and displays. I want to be able to create a form on the home page to allow people to select the 'make', which will then update the 'models' list based on the 'make' the user selects, 'year' to and from, and 'amount' to and from. What the user selects will of course alter the list of used cars, whether that's on the existing used cars page or a new page. I would be happy to create a custom module if required, just need some direction. Thanks !

  • if cookies are disabled, does asp.net store the cookie as a session cookie instead or not?

    - by Erx_VB.NExT.Coder
    basically, if cookeis are disabled on the client, im wondering if this... dim newCookie = New HttpCookie("cookieName", "cookieValue") newCookie.Expires = DateTime.Now.AddDays(1) response.cookies.add(newCookie) notice i set a date, so it should be stored on disk, if cookies are disabled does asp.net automatically store this cookie as a session cookie (which is a cookie that lasts in browser memory until the user closes the browser, if i am not mistaken).... OR does asp.net not add the cookie at all (anywhere) in which case i would have to re-add the cookie to the collection without the date (which stores as a session cookie)... of course, this would require me doing the addition of a cookie twice... perhaps the second time unnecessarily if it is being stored in browsers memory anyway... im just trying not to store it twice as it's just bad code!! any ideas if i need to write another line or not? (which would be)... response.cookies.add(New HttpCookie("cookieName", "cookieValue") ' session cookie in client browser memory thanks guys

Index page shows all upcoming dinners: public ActionResult Index() { var dinners = dinnerRepository.FindUpComingDinners().ToList(); return View(dinners); } In DinnerRepository class I have method FindAllDinners and I would like to add to above Index method number of all dinners, something like this: public ActionResult Index() { var dinners = dinnerRepository.FindUpComingDinners().ToList(); var numberOfAllDinners = dinnerRepository.FindAllDinners().Count(); return View(dinners, numberOfAllDinners); } Of course, this doesn't work. As I'm pretty new to OOP I would need help with this one. Thanks, Ile

  • Application Context in Rails

    - by Sean McMains
    Rails comes with a handy session hash into which we can cram stuff to our heart's content. I would, however, like something like ASP's application context, which instead of sharing data only within a single session, will share it with all sessions in the same application. I'm writing a simple dashboard app, and would like to pull data every 5 minutes, rather than every 5 minutes for each session. I could, of course, store the cache update times in a database, but so far haven't needed to set up a database for this app, and would love to avoid that dependency if possible. So, is there any way to get (or simulate) this sort of thing? If there's no way to do it without a database, is there any kind of "fake" database engine that comes with Rails, runs in memory, but doesn't bother persisting data between restarts?

  • Inserting Rows in Relationship using a Strongly Typed DataSet

    - by Manuel Faux
    I'm using ADO.NET with a strongly typed dataset in C# (.NET 3.5). I want to insert a new row to two tables which are related in an 1:n relation. The table Attachments holds the primary key part of the relation and the table LicenseAttachments holds the foreign key part. AttachmentsDataSet.InvoiceRow invoice; // Set to a valid row, also referenced in InvoiceAttachments AttachmentsDataSet.AttachmentsRow attachment; attachment = attachmentsDataSet.Attachments.AddAttachmentsRow("Name", "Description"); attachmentsDataSet.InvoiceAttachments.AddInvoiceAttachmentsRow(invoice, attachment); Of course when I first update the InvoicesAttachments table, I'll get a foreign key violation from the SQL server, so I tried updating the Attachments table first, which will create the rows, but will remove the attachment association in the InvoiceAttachments table. Why? How do I solve this problem?

  • Master's in Software Engineering vs. Master's in Computer Science: which degree is preferred by empl

    - by dbarker
    I've been building software professionally for 7 years and am considering a master's degree. I understand the difference between these two degrees as simply: MSCS is the theory while MSE is the practice. I'm equally interested in both and would be happy with either, although I'm curious how these degrees rank in the eyes of a potential employer. I could see two views that a hiring manager could possibly take: a MSCS is loftier and has an implied knowledge of Software Engineering an MSE is more practical and has an implied knowledge of Computer Science In my own experience I've seen both MSCS degree holders than cannot program at all while others are among the best programmers I've met, so of course actual ability will depend on the individual. My question is about the "on paper" value of these two degrees when seeking a job. All things considered, is one degree more hirable, higher-paying than the other?

  • Attaching a static library to an iphone/ipad application

    - by Jack
    Hello, which is the best approach to include a static library with into an application for iPhone or iPad? I could choose to compile the library supplying right platform and building a library file with the ar utility and then add as a framework to the project including the source of the library .c/.h and compile them together with the application The first approach seems simpler, because I won't care about managing all specific settings of the library I want to include but how can I create the library both for iPhone and iPad and allow xcode to use the right library upon linking? The second approach seems more complex since xcode will take care about compiling my application and the library (with different settings I suppose) then how should I go? I can easily add sources of the lib but I'll have to include the make scripts to allow xcode use them to build in the right way. Any suggestions about how to proceed? The library I'm trying to include is libssh. (I know that this library, of course, has already been compiled and tried succesfully on iPhone) Thanks in advance.

  • After using modern languages, can C NOT be painful?

    - by Alexandre
    I started my computer engineering course recently and we've been using C for a couple of things. Before starting university, I was doing a lot of web development. I've written a lot of PHP code (yuck!) and for the last year or so Ruby exclusively. aside: I love Ruby, love it! So after a year of heavy Ruby development, is it wrong to think that C should be avoided at all costs unless absolutely necessary? Right now it seems to me I should try to a) get it to run in Ruby b) if it's too slow, try Java c) if it's too slow, use C Is there anyone who jumps straight to C if a VM (Ruby, Java, Python, etc) can be used on the machine and speed is not an issue? In other words, can C NOT be painful?

  • DragDrop-Support of PictureBox-Control

    - by Effdee
    After some searching i figured out how dragdrop is implemented for a picturebox. But there is one thing - the (inherited of course) allowdrop property isn't accessible from code or property window of picturebox class. So to make it work i added following line to my form-load: ((Control)pictureBox1).AllowDrop = true; Why do i have to do that? In msdn it says: "This API supports the .NET Framework infrastructure and is not intended to be used directly from your code." Any explanation appreciated and sorry for my grammar ;)

  • Is there a COM object that just implements IUnknown I can use?

    - by Matt
    For an asynchronous Windows API, I can provide an IUnknown state parameter to associate calls to the API with calls from the callback. It's my understanding that COM guarantees that two IUnknown pointers to the same object will be of the same value. Thus, if I only want to associate API calls with callbacks, IUnknown should be all I need, by comparing the values of the pointers. Is there a stock implementation of IUnknown I can use? Of course it would be trivial to implement myself, but for such a base component of COM, I'm wondering if Windows or ATL provides one I should use instead. Thanks, --Matt

  • Should I work with multiple recruiters for a job search or just pick one?

    - by BuckeyeSoftwareGuy
    So I posted my resume on dice and monster last night and today I've received 5 voicemails and about 6 emails from different recruiters wanting to talk to me. What's the best way to handle this situation. I want to reply to them all of course as I'm very interested in making an imminent job change. Is there some sort of rule of thumb here? It seems to me they would want to work with me exclusively if they could. I don't want to limit my options though..

  • Building a GPS Tracking Web System

    - by zakaria
    Hi everybody, I'd like to develop a tracking system using an API of course (like the famous Orange API). the idea is simple: I send a SMS (from my Web interface) to the person i want to track The person's mobile terminal (GPS like this) send me back automatically the coordinates by SMS. The sent information are displayed on the user's web interface. The questions are simple: How the terminal can send automatically the response? How to indicate in the message that the information is for "user4655"? How to make connection between the information and the database? Thanks, Regards.

  • Strange behavior in DockPanel

    - by plotnick
    I don't understand, I have a toolbar with buttons bind to custom commands. Also I have an expandable control docked to the left of window - kinda NavPanel. (Devcomponents' NavigationPane to be exact) Now, everytime when it's collapsed or expanded, buttons in the toolbar become disabled and stay like that till the focus changes. Of course, it's simple to change the focus inside Collapsed and Expanded events, but unfortunately it works only in the first and ignores the second one and all buttons stay disabled. It seems that it something to do with CommandTarget which I haven't define nowhere. Maybe I should? Any ideas?

  • How divide a GWT module into some separate javascript files ?

    - by Ehsan Khodarahmi
    Hi, I've a big GWT module which comprised of many java classes (& of course it's impossible to break it down into several modules). My GWT application consists of some forms, but the users usually work only with a few of them, anyway they should be abale to open any form as they need. Now my problem its that gwt generates a big js file that will load each time, but most of its content may never use! Is there any way to break the big js module file into several smaller files(for example, one file for each class) & gwt load them automatically as needed ?

  • Implementing fallback from Google AJAX Libraries API to local jQuery

    - by Maxim Z.
    After looking up the advantages and disadvantages of using Google's AJAX Libraries API instead of using jQuery locally, I saw that someone wrote in an answer (here on Stack Overflow, of course) that it's possible to get around the downtime that Google's API sometimes experiences by somehow falling back to a local copy of the library you use. I want to use Google's AJAX Libraries API on my site, but I'm concerned about this possible downtime and I'm curious how such a fallback procedure can be implemented. Has anybody ever tried doing this? Can you point me towards some code that accomplishes such a feat? Thanks in advance.

  • Discrete mathematics problem - Probability theory and counting

    - by Mohammad
    Hello All, I'm taking a discrete mathematics course, and I encountered a question and I need your help. I don't know if this is the right place for that though :) It says: Each user on a computer system has a password, which is six to eight characters long, where each character is an uppercase letter or a digit. Each password must contain at least one digit. How many possible passwords are there? The book solves this by adding the probabilities of having six,seven and eight characters long password. However, when he solves for probability of six characters he does this P6 = 36^6 - 26^6 and does P7 = 36^7 - 26^7 and P8 = 36^8 - 26^8 and then add them all I understand the solution, but my question is why doesn't calculating, P6 = 10*36^5 and the same for P7 and P8, work? 10 for the digit and 36 for the alphanumeric? Also, if anyone could give me another solution, other than the one in the book. Thank you very much :)

  • javascript removeChild() and appendChild() VS display=none and display=block|inline

    - by Kucebe
    I'm developing a web application that shows some controls and descriptions dinamically (I don't want to use jQuery or other libraries). At this moment i make appear and disappear controls using: element.setAttribute("style", "inline"); and element.setAttribute("style", "none"); but i'm thinking about using: element.appendChild(childRef); and element.removeChild(childRef); So, which one is the best solution in terms of system speed and elegance of the code? (and of course, are there better solution?)

  • SVN Delete with wildcard?

    - by David Lively
    I'm migrating a VSS repository to SVN and inadvertently included all of the _vti_cnf, *.scc files in the first check-in. I'd like to remove these from SVN. (Not permanently, of course - just in the HEAD). The application in question is quite large, and finding and deleting these files on a folder-by-folder basis will take forever. Suggestions? There must be some obvious way to do this, but the proximity of the weekend is interfering with my higher brain functions.

  • Can I make clojure macro that will allow me to get a list of all functions created by the macro?

    - by Rob Lachlan
    I would like to have a macro which I'll call def-foo. Def-foo will create a function, and then will add this function to a set. So I could call (def-foo bar ...) (def-foo baz ...) And then there would be some set, e.g. all-foos, which I could call: all-foos => #{bar, baz} Essentially, I'm just trying to avoid repeating myself. I could of course define the functions in the normal way, (defn bar ...) and then write the set manually. A better alternative, and simpler than the macro idea, would be to do: (def foos #{(defn bar ...) (defn baz ...)} ) But I'm still curious as to whether there is a good way for the macro idea to work.
