  • ToolStripComboBox + objects default string value

    - by Martin
    I am using a ToolStripComboBox to list some data. I am populating this combo with some custom objects: For Each obj As myObject In myObjectList myToolStripComboBox.Items.Add(obj) Next This works great except the text displayed in the combo is the name of the object class. I can understand why and realise that I need to do something to make the combo use a property from my class instead. The help files state: To add objects to the list at run time, assign an array of object references with the AddRange method. The list then displays the default string value for each object. You can add individual objects with the Add method. The bit in bold suggests I need to setup the default string value in my class. How would I go about doing this?

  • C# "Could not find a part of the path" - Creating Local File

    - by Pyronaut
    I am trying to write to a folder that is located on my C:\ drive. I keep getting the error of : Could not find a part of the path .. etc My filepath looks basically like this : C:\WebRoot\ManagedFiles\folder\thumbs\5c27a312-343e-4bdf-b294-0d599330c42d\Image\lighthouse.jpg And I am writing to it like so : using (MemoryStream memoryStream = new MemoryStream()) { thumbImage.Save(memoryStream, ImageFormat.Jpeg); using (FileStream diskCacheStream = new FileStream(cachePath, FileMode.CreateNew)) { memoryStream.WriteTo(diskCacheStream); } memoryStream.WriteTo(context.Response.OutputStream); } Don't worry too much about the memory stream. It is just outputting it (After I save it). Since I am creating a file, I am a bit perplexed as to why it cannot find the file (Shouldn't it just write to where I tell it to, regardless?). The strange thing is, It has no issue when I'm testing it above using File.Exists. Obviously that is returning false, But it means that atleast my Filepath is semi legit. Any help is much appreciated.

  • Performance of fopen vs stat

    - by Alex Marshall
    Hello, I'm writing several C programs for an embedded system where every bit of performance we can squeeze out will matter. Part of that is accessing log files. When determining if a file exists, is there any performance difference between using open / fopen, and stat ? I've been using stat on the assumption that it only has to do a quick check against the file system, whereas fopen would have to actually gain access to a file and manipulate internal data structures before returning. Is there any merit to this ?

  • MATLAB fill area between lines

    - by dustynrobots
    I'm trying to do something similar to what's outlined in this post: MATLAB, Filling in the area between two sets of data, lines in one figure but running into a roadblock. I'm trying to shade the area of a graph that represents the mean +/- standard deviation. The variable definitions are a bit complicated but it boils down to this code, and when plotted without shading, I get the screenshot below: x = linspace(0, 100, 101)'; mean = torqueRnormMean(:,1); meanPlusSTD = torqueRnormMean(:,1) + torqueRnormStd(:,1); meanMinusSTD = torqueRnormMean(:,1) - torqueRnormStd(:,1); plot(x, mean, 'k', 'LineWidth', 2) plot(x, meanPlusSTD, 'k--') plot(x, meanMinusSTD, 'k--') But when I try to implement shading just on the lower half of the graph (between mean and meanMinusSTD) by adding the code below, I get a plot that looks like this: fill( [x fliplr(x)], [mean fliplr(meanMinusSTD)], 'y', 'LineStyle','--'); It's obviously not shading the correct area of the graph, and new near-horizontal lines are being created close to 0 that are messing with the shading. Any thoughts? I'm stumped.

  • Most elegant way to morph this sequence

    - by Ed Woodcock
    Hi folks: I've got the Day of the week stored in a database table (that I do not control), and I need to use it in my code. Problem is, I want to use the System.DayOfWeek enum for representation for this, and the sequences are not the same. In the database, it's as follows: 1 2 3 4 5 6 7 S M T W T F S I need it as follows: 0 1 2 3 4 5 6 M T W T F S S What's the most elegant way to do this? for example, I could do: i = dayOfWeek; i = i - 2; if (i < 0) { i = 6; } but that's a bit inelegant. Any suggestions?

  • matlab fit exp2

    - by HelloWorld
    I'm unsuccessfully looking for documentation of fit function using exp2 (sum of 2 exponents). How to operate the function is clear: [curve, gof] = fit(x, y,'exp2'); But since there are multiple ways to fit a sum of exponents I'm trying to find out what algorithm is used. Particularly what happens when I'm fitting one exponent (the raw data) with a bit of noise, how the exponents are spread. I've simulated several cases, and it seems that it "drops" all the weight on the second set of coefficients, but row data analysis often shows different behavior. Does anyone have suggestions of documentation?

  • Wrapper not resizing to full content size

    - by Moppy
    Hey guys, I have a div called #background. I have most of my content in it and I want it to resize when I add more content. As far as I know the way to do this is to assign it no height? I have done this in my layout.css file. As far as I can see, my #background doesnt close until after the last bit of content which is what I want, but it's not working. It seems to be just stopping after my #special offers div, I#m not sure why this is? Colm

  • question about select() and range of for loop to read sockets

    - by Fantastic Fourier
    Just a quick question about using select(). I'm using select() to read from multiple sockets. When I looked up examples on how to use select(), a lot of tutorials showed going through for loops and checking for FD_ISSET. The problem I have with those tutorials is that the for loop starts from i = 0. and checks if the bit has been set for the file descriptor i using FD_ISSET. Couldn't the for loop start from say your minfd (just like how you would keep track of maxfd)?? Or am I missing something?? Following link is an example of such for loop (look at the fourth example that he gives) http://www.developerweb.net/forum/showthread.php?t=2933 If that was the only example out there that used such for loop, I might understand it was a mistake or bad coding but I've seen several examples of such for loop of uselessly going through literally thousands of sockets and I'm convinced I'm missing something. Any comments or inputs are appreciated.

  • Typed Arrays in Gecko 2: Float32Array concatenation and expansion.

    - by janesconference
    Hi all, I'm a bit confused with Javascript Typed Arrays. What I have several *Float32Array*s, that have no concat method. I'd like to concatenate them all inside another Float32Array, but: as I said before, there is no concatenation method if I try to write past the array length, the array is not expanded (aka this won't work - please note that event.frameBuffer and buffer are both Float32Array and that I don't know what the final length of my buffer will be): var length_now = buffer.length; for (var i = 0; i < event.frameBuffer.length; i += 1) { buffer [length_now + i] = event.frameBuffer[i]; } The only solution I found is to copy the Float32Array in a regular array, that's definitely not what I want. How would you do, stackoverflowers?

  • [Alfresco] property qualified-name in method getContentReader

    - by Ar3s
    Hi there, I first apologize for my poor english level and maybe for the stupidity of my question ;) I am on an alfresco project to learn how it works. I have to browse programatically my content repository and gather datas all along. In order to do that I guessed I had to use a ContentReader (I get from my ContentService) but the method getReader wants a nodeRef and a propertyQualifiedName. I am ok with the nodeRef, I get what it's needed for. But the propertyQualifiedName puzzles me, I barely get what it is but I frankly don't get how it is used. Reading some alfresco forum threads I get more and more scared that I dont even get how a reader works, I somewhere saw that a reader can read only one node and only one time per instance. If anyone knows a bit about the Java API for Alfresco Content Repository use I am all hears ! Cheers all !

  • 'script/console test' with spork and rspec not loading the whole environment?

    - by TheDeeno
    I'm trying to load up console to interact with some of my rspec mocking helpers. I expected that running script/console test would load an env similar to when I run spec. However, this doesn't appear to be the case. It looks like spec_helper is never loaded. Or, if it is, it's not actually running through the logic because spork has polluted it a bit. In short, is there a quick and easy way to get an interactive rspec party going?

  • How to refresh an activity? Map View refresh fails

    - by poeschlorn
    Hi Guys, after implementing some Android Apps, including several Map activities, I try to refresh the activity when the GPS listener's onLocationChanged() mehtod is called. I have no idea how to tell the map activity to refresh on its own and display the new coords... the coords to store will have to be in global values, so that the location listener will have access to it. In my sample GPS-class (see code below) I just changed the text of a text view....but how to do that in map view? private class MyLocationListener implements LocationListener { @Override public void onLocationChanged(Location loc) { final TextView tv = (TextView) findViewById(R.id.myTextView); if (loc != null) { tv.setText("Location changed : Lat: " + loc.getLatitude() + " Lng: " + loc.getLongitude()); } } I think the solution of this Problem won't be very difficult, but I just need the beginning ;-) This whole app shall work like a really simple navigation system. It would be great if someone could help me a little bit further :) nice greetings, Poeschlorn

  • .NET Application using a native DLL (build management)

    - by moogs
    I have a .NET app that is dependent on a native DLL. I have the .NET app set as AnyCPU. In the post-build step, I plan to copy the correct native DLL from some directory (x86 or AMD64) and place it in the target path. However, this doesn't work. On a 64-bit machine, the environment variable PROCESSOR_ARCHITECTURE is "x86" in Visual Studio. My alternative right now is to create a small tool that outputs the processor architecture. This will be used by the post-build step. Is there a better alternative? (Side Note: when deploying/packaging the app, the right native DLL is copied to the right platform. But this means we have two separate release folders for x86 and AMD64, which is OK since this is for a device driver. The app is a utility tool for the driver).

  • How does sizeof calculate the size of structures

    - by Gearoid Murphy
    I know that a char and an int are calculated as being 8 bytes on 32 bit architectures due to alignment, but I recently came across a situation where a structure with 3 shorts was reported as being 6 bytes by the sizeof operator. Code is as follows: #include <iostream> using namespace std ; struct IntAndChar { int a ; unsigned char b ; }; struct ThreeShorts { unsigned short a ; unsigned short b ; unsigned short c ; }; int main() { cout<<sizeof(IntAndChar)<<endl; // outputs '8' cout<<sizeof(ThreeShorts)<<endl; // outputs '6', I expected this to be '8' return 0 ; } Compiler : g++ (Debian 4.3.2-1.1) 4.3.2. This really puzzles me, why isn't alignment enforced for the structure containing 3 shorts?

  • Kohana3 - Auth Module deleting User while he is logged in bug

    - by ahmet2106
    Hello Stackoverflow Users, Today I've tested the Kohana3, which has been changed a lot. I'm working so much with the Auth Module, and need this in my new Project also. Now I found a Bug, I think it is a bug, what can I do? Problem: After I'm deleting a user from the Database, who is at this Moment logged_in() in my Website, and he is refreshing the page, he will be logged_in() as the first user out of the PRAEFIX_users Table. Even if he is deleted. And 99% this is an Administrator. My function which is checking and redirecting if he is not logged_in(): if(!Auth::instance()->logged_in()) { $this->request->redirect( 'login' ); } How can i change my Check Login so, that if he is deleted, he will be redirected to login (/login/) ? Here the same Thread at Kohana Forums, but I hope and think, stackoverflow is a litte bit faster :)

  • What if I have an API method and a contoller/view method with the same name in RoR?

    - by Chad Johnson
    Suppose I want to be able to view a list of products on my site by going to /product/list. Great. So this uses my 'list' view and outputs some HTML which my web browser will render. But now suppose I want to provide a REST API to my client where they can get a list of their products. So I suppose I'd have them authenticate with oAuth and then they'd call /product/list which would return a JSON array of their products. But like I said earlier, /product/list displays an HTML web page. So, I have a conflict. What is normal practice as far as providing APIs in Rails? Should I have a subdirectory, 'api', in /app/controller, and another 'product' controller? So my client would go to /api/product/list to get a list of their products? I'm a bit new to RoR, so I don't have the best grasp of the REST functionality yet, but hopefully my question makes sense.

  • How do I change careers to become a programmer with little money

    - by bgc83
    I'm currently a network engineer, but find myself wanting to get into the world of development. I took a little bit of Java in college, am 27 years old and have been network engineering for 4 years now. I have a mortgage and student loans so going back to school would be difficult. I'm willing to put in however much hardwork is needed around my full time job to learn, but part of me feels I may need actuall schooling to get down some of the advanced concepts. Just looking for a little advice and direction. I have purchased a bunch of the Head First programming books and have begun reading through some of them as I figure out my way into this transition.

  • using crypto++ on iphone sdk with pycrypto on app engine

    - by Joey
    Hi, I'm trying to encrypt http requests using crypto++ and decrypt them with pycrypto on the app engine server end. Using Arc4 encryption, I can successfully encrypt and decrypt on the iphone end but when I try decrypting on app engine, the result is garbled. I thought maybe it has something to do with the encoding of the NSString but am not certain. It's not clear to me if I need to call encode() on the cipher on the server end before decrypting, although that does seem to resolve a failure to decrypt involving ascii values. I have a separate post that delves a bit into this. Can anyone offer some advice? http://stackoverflow.com/questions/2794942/crypto-pycrypto-with-google-app-engine

  • Silverlight/Web Service Serializing Interface for use Client Side

    - by Steve Brouillard
    I have a Silverlight solution that references a third-party web service. This web service generates XML, which is then processed into objects for use in Silverlight binding. At one point we the processing of XML to objects was done client-side, but we ran into performance issues and decided to move this processing to the proxies in the hosting web project to improve performance (which it did). This is obviously a gross over-simplification, but should work. My basic project structure looks like this. Solution Solution.Web - Holds the web page that hosts Silverlight as well as proxies that access web services and processes as required and obviously the references to those web services). Solution.Infrastructure - Holds references to the proxy web services in the .Web project, all genned code from serialized objects from those proxies and code around those objects that need to be client-side. Solution.Book - The particular project that uses the objects in question after processed down into Infrastructure. I've defined the following Interface and Class in the Web project. They represent the type of objects that the XML from the original third-party gets transformed into and since this is the only project in the Silverlight app that is actually server-side, that was the place to define and use them. //Doesn't get much simpler than this. public interface INavigable { string Description { get; set; } } //Very simple class too public class IndexEntry : INavigable { public List<IndexCM> CMItems { get; set; } public string CPTCode { get; set; } public string DefinitionOfAbbreviations { get; set; } public string Description { get; set; } public string EtiologyCode { get; set; } public bool HighScore { get; set; } public IndexToTabularCommandArguments IndexToTabularCommandArgument { get; set; } public bool IsExpanded { get; set; } public string ManifestationCode { get; set; } public string MorphologyCode { get; set; } public List<TextItem> NonEssentialModifiersAndQualifyingText { get; set; } public string OtherItalics { get; set; } public IndexEntry Parent { get; set; } public int Score { get; set; } public string SeeAlsoReference { get; set; } public string SeeReference { get; set; } public List<IndexEntry> SubEntries { get; set; } public int Words { get; set; } } Again; both of these items are defined in the Web project. Notice that IndexEntry implments INavigable. When the code for IndexEntry is auto-genned in the Infrastructure project, the definition of the class does not include the implmentation of INavigable. After discovering this, I thought "no problem, I'll create another partial class file reiterating the implmentation". Unfortunately (I'm guessing because it isn't being serialized), that interface isn't recognized in the Infrastructure project, so I can't simply do that. Here's where it gets really weird. The BOOK project CAN see the INavigable interface. In fact I use it in Book, though Book has no reference to the Web Service in the Web project where the thing is define, though Infrastructure does. Just as a test, I linked to the INavigable source file from indside the Infrastructure project. That allowed me to reference it in that project and compile, but causes havoc in the Book project, because now there's a conflick between the one define in Infrastructure and the one defined in the Web project's web service. This is behavior I would expect. So, to try and sum up a bit. Web project has a web service that process data from a third-party service and has a class and interface defined in it. The class implements the interface. The Infrastructure project references the web service in the Web Project and the Book project references the Infrastructure project. The implmentation of the interface in the class does NOT serialize down, so the auto-genned code in INfrastructure does not show this relationship, breaking code further down-stream. The Book project, whihc is further down-stream CAN see the interface as defined in the Web Project, even though its only reference is through the Infrastructure project; whihc CAN'T see it. Am I simple missing something easy here? Can I apply an attribute to either the Interface definition or to the its implmentation in the class to ensure its visibility downstream? Anything else I can do here? I know this is a bit convoluted and anyone still with me here, thanks for your patience and any advice you might have. Cheers, Steve

  • Footer height based on screen size

    - by o-logn
    Hi everyone, I would like to create a footer which is relative to the content (so not fixed), but fills the rest of the screen. So for example, on my larger monitor, the footer would start in the same place, but fill up 100px (for example). On a smaller monitor, it only needs to fill up 75px. I tried using 100%, but it causes the page to be really big and the user can scroll down and fill the entire screen with the footer. Is there a way to get it to be a bit more reasonable size, so that it just about fills the bottom of the screen? My current code is this: .footer { position:relative; //can't be fixed as content might overlap if extended height:100%; width:100%; //fill the entire screen horizontally bottom:0px; margin-top:345px; //used to make sure content doesn't overlap } Thanks for any ideas

  • Ruby on Rails - where to write business logic while processing a request? (newbie)

    - by Genadinik
    I am learning Ruby on Rails. I made a simple link like this: <%= link_to "Alex Link", alexes_path(@alex) %> then I routed it in routes.rb like this: resources :alexes get "home/index" then I am a bit unclear, but I think it goes to this part of the controller: def index #@alexes = Alex.all respond_to do |format| format.html # index.html.erb format.json { render json: @alexes } end end Am I correct that it goes to this part of the controller? Then nothing much happens and it goes to the next page which is index.html.rb under views\alexes So what I am wondering is - if I needed to do some business logic, would I write that in the controller snippet? Where inside the snippet? An example would be nice to take a look. Also, I would like to connect to a MongoDb database. Would I also write that in the middle of the controller? Thanks!

  • getting a gridview and dropdownlist to remember their states after navigate away and back button scr

    - by nat
    hi i have a page filling a gridview which is all working fine. the grid is basically the result of a search .. the filters for which are a number of dropdowns and a couple of textboxes the data from the grid and dropdowns are saved in the session and the whole page lives inside an updatepanel when i navigate away from the page (as it happens by clicking a link inside the grid) and then back button to it, all the droppers are back to their unselected values and the grid is nowhere to be seen.. i understand that this is because of the scriptmanager doesnt do 'standard' postbacks so the browser doesnt realise what has happened. however i have set the EnableHistory to true in the scriptmanager is there an easy way to get this to remember without dropping the updatepanel/scriptmanager? also to complicate things further the scriptmanger /updatepanel is actually in a master page. so not really sure how i can get the navigate bits to work in the scriptmanager.. clearly i am a bit confuised and any help that someone could provide would be happily received thanks nat

Things I've tried: 1) In options/options/current database/ the check boxes (enable layout view & enable design changes for tables in Datasheet view) are both greyed out. 2) I've unblocked the file using Right-Click-Properties. 3) I've tried copying/exporting the objects to another database. But can only copy/export the tables. 4) I've tried holding shift when opening the DB. 5) Enabling all trust permissions etc. None of these work Does anybody have any suggestions.
