  • F# List of functions

    - by akaphenom
    I am trying to have a list of functions, but seem to be comming up empty handed. The basic code is something like this: let doSomething var = var let doSomething2 var = var let listOfStuff = [doSomething doSomething2] and I am getting the followiung exception: Error 2 Value restriction. The value 'listOfStuff' has been inferred to have generic type val queue : ('_a - '_a) list Either define 'queue' as a simple data term, make it a function with explicit arguments or, if you do not intend for it to be generic, add a type annotation. C:\fsharp\SentimentFramework\TradeSignalProcessor\Program.fs 16 9 TradeSignalProcessor I tried addin the [] attribute but that didn't work...

  • How to structure VB.NET windows forms applications

    - by Jon
    What is the best way to structure a VB.NET windows forms application so that code can be reused and the app can be extended easily. I used to create lots of new forms. This lead to lots of repeated code and forms which did similar things. Now, for forms which do similar jobs, such as view/edit/delete items from a specific db table, I create a form with the required controls, have the form create an instance of a class with params such as a collection of the controls and a string containing the db table name. Then the individual controls call functions of the class. Advanced forms will inherit and extend this basic form class. 1) Has there already been work done in this area? 2) Are there books / articles available which discuss the options available on this topic? Thanks!

  • Haskell Convert Byte String To UTC Time

    - by Steve
    I have been trying to make a function in Haskell to take a ByteString which is a datetime and convert it to UTC time taking into account the time zone from the original encoding. I am very new to Haskell so I may be making a really basic mistake. convertStringToUtc s = do estTimeZone <- hoursToTimeZone -5 time <- read $ B.unpack(s) localTimeToUTC estTimeZone time The error I get is: Couldn't match expected type `Int -> b' against inferred type `UTCTime' In the expression: localTimeToUTC estTimeZone time In the expression: do { estTimeZone <- hoursToTimeZone - 5; time <- read $ B.unpack (s); localTimeToUTC estTimeZone time }

  • Silverlight File download from client

    - by luke
    I have a Silverlight application that implements some basic CRUD operations on a fairly flat data set. The application loads all the data onto the client to allow for quick editing (this is a fairly small data set no more that a couple K). I would like to allow them to download the file as a CSV so they can edit the data locally. I know i can set up a HyperLink button to a URL on my webserver and then server the data dynamically using a custom server handler. But this seems kind of roundabout to me because the all the data is already all on the Client's machine (because the Silverlight application loaded it). So i was wondering if there was a way to prompt the user for a file download and then dynamically generate the file download stream from Silverlight?

  • How to detect flash based music player is done with playing music

    - by rsapru
    Hi, I am trying to create a very basic\ minimalistic playlist application for http://www.google.co.in/music. Basically Google music displays links to song and when clicked it opens flash based player. Using my application i am collecting music links into a list box, when an song is clicked it opens the link in a separate webbrowser and it starts playing. As of now to achieve playlist functionality i also collect the time for each song and based on that i create a timer, once the time is over it switches to other song. My Question here is that, is it possible to detect when the flash player is done playing music. Currently the timer functionality that i have built is not reliable. If interested you can have a look at code http://gmp.codeplex.com/

  • Brute force characters into a textbox in c#

    - by Fred Dunly
    Hey everyone, I am VERY new to programming and the only language I know is C# So I will have to stick with that... I want to make a program that "test passwords" to see how long they would take to break with a basic brute force attack. So what I did was make 2 text boxes. (textbox1 and textbox2) and wrote the program so if the text boxes had the input, a "correct password" label would appear, but i want to write the program so that textbox2 will run a brute force algorithm in it, and when it comes across the correct password, it will stop. I REALLY need help, and if you could just post my attached code with the correct additives in it that would be great. The program so far is extremely simple, but I am very new to this, so. Thanks in advance. private void textBox2_TextChanged(object sender, EventArgs e) { } private void button1_Click(object sender, EventArgs e) { if (textBox2.Text == textBox1.Text) { label1.Text = "Password Correct"; } else { label1.Text = "Password Wrong"; } } private void label1_Click(object sender, EventArgs e) { } } } `

  • Comparing two Oracle schema, other users

    - by Igman
    Hello! I have been tasked with comparing two oracle schema with a large number of tables to find the structural differences in the schema. Up until know I have used the DB Diff tool in Oracle SQL Developer, and it has worked very well. The issue is that now I need to compare tables in a user that I cannot log into , but I can see it through the other users section in SQL developer. The issue is that whenever I try to use the diff tool to compare those objects to the other schema it does not work. Does anyone have any idea how to do this? It would save me a very large amount of work. I have some basic SQL knowledge if that is whats needed. Thanks.

  • Is it possible to reset NSURLConnection after providing credentials?

    - by John
    I am calling a REST service that requires basic auth and I respond to the didReceiveAuthenticationChallenge delegate OK NSURLCredential *credential = [[NSURLCredential alloc] initWithUser:self.user password:self.password persistence:NSURLCredentialPersistenceForSession]; [[challenge sender] useCredential:credential forAuthenticationChallenge:challenge]; [credential release]; The Credentials are valid for the Session but I would like for my App to be able to switch between servers and therefore need to "reset" the Session so it asks again for a challenge. I can of course try the option of not storing the credentials for the Session and supply them for each call but this does not seem like a good idea. Any ideas would be appreciated!

  • Capturing network traffic in ruby - pcap related issues

    - by Acidburn2k
    What I need is to write very simple application, which would listen to network traffic, filter out some packets based on various layer 4/5 information and then dump those information into database. I am quite confused on which pcap gem/plugin should I use. The basic pcap implemention seem to be a bit outdated (no changes since 2001) and doesn't work properly. I also tried pcaprub, but I am not quite sure how to get around with this library. It seem to capture raw packets without te ability to actualy get any data out of the pcap dump. Do you have any advices on how can I realize this simple task? Thanks in advance. :-)

  • Copy hashtable to another hashtable using c++

    - by zengr
    I am starting with c++ and need to know, what should be the approach to copy one hashtable to another hashtable in C++? We can easily do this in java using: HashMap copyOfOriginal=new HashMap(original); But what about C++? How should I go about it? UPDATE Well, I am doing it at a very basic level,perhaps the java example was a wrong one to give. This is what I am trying to implement using C++: I have this hash array and each element of the array point to the head of a linked list. Which has it's individual nodes (data and next pointer). And now, I need to copy the complete hash array and the linked list each node is pointing to.

  • Microsoft flexgrid Control : Run-time error '438' Object doesnt support this property or method

    - by Dan
    I am maintaining a legacy Microsoft Access application that is using the Microsoft Flexgrid 6.0. It recently started causing the following error: Run-time error '438' Object doesn't support this property or method People say that this error can be caused by the KB960715 security update being applied, which sets killbits on various ActiveX control methods which were deemed a security risk. But this or no other security update has been applied recently. Others say that installing Microsoft Visual Basic 6.0 Service Pack 6 Cumulative Update will update the flex grid. This requires VB6 to be installed as a prerequisite so I installed that on my PC and then the update, and retrieved the updated MsFlxGrd.ocx file(Version: 6.1.98.12) and copied to the application machine, but the error still prevails. Someone here says you can disable the killbit in the registry. But there are afew hundred nodes in the location they suggest, none of which has the same guid as the one they point out. Any ideas?

  • Where to place ClientAccessPolicy.xml for Local WCF Service?

    - by cam
    I'm trying to create a basic WCF Service and Silverlight client. I've followed the following tutorial: http://channel9.msdn.com/shows/Endpoint/Endpoint-Screencasts-Creating-Your-First-WCF-Client/ Since Silverlight 4 was incompatible with the WSHttpBinding, I changed it to BasicHttpBinding. Unfortunately I keep getting this error now: "An error occurred while trying to make a request to URI'**'.This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent." I placed clientaccesspolicy.xml in the root directory of the WCF project (which is in the same solution as the Silverlight client). This did not solve the problem. What do I need to do?

  • Silverlight RIA Services. Query fails on large table but works with Where clause

    - by FauxReal
    I have a somewhat large table, maybe 2000 rows by 50 columns. When using the most basic imaginable RIA implementation. Create one-table Model Create DomainService Drop datagrid onto MainPage.xaml Drop datasource onto datagrid Ctrl-F5 I get this error: System.ServiceModel.DomainServices.Client.DomainOperationException: Load operation faild for query. Value cannot be null. Error is much larger, but thats the beginning of it. The weird thing is that if I narrow the results down with a where clause on the GetQuery, it works fine. In fact six different querys which together result in all of the rows being called works fine also. So basically, I'm sure its not some sort of rogue row. Why do I get this "Value cannot be null" error if I query the whole table? Thanks

  • Dyanamic Chart Series Labels

    - by McVey
    I have some Visual Basic Code that creates a chart for each row. It sets the series values using this code: .SeriesCollection(1).Values = "=" & Ws.Name & "!R" & CurrRow & "C3:R" & CurrRow & "C8" What I am struggling with is how do I set the series labels? The series labels will always be the 1st row and be in the corresponding column. I know this is much simplier than the code above, but I am stumped. Any help is appreciated.

  • Homoscedascity test for Two-Way ANOVA

    - by aL3xa
    I've been using var.test and bartlett.test to check basic ANOVA assumptions, among others, homoscedascity (homogeniety, equality of variances). Procedure is quite simple for One-Way ANOVA: bartlett.test(x ~ g) # where x is numeric, and g is a factor var.test(x ~ g) But, for 2x2 tables, i.e. Two-Way ANOVA's, I want to do something like this: bartlett.test(x ~ c(g1, g2)) # or with list; see latter: var.test(x ~ list(g1, g2)) Of course, ANOVA assumptions can be checked with graphical procedures, but what about "an arithmetic option"? Is that manageable? How do you test homoscedascity in Two-Way ANOVA?

    I've been using var.test and bartlett.test to check basic ANOVA assumptions, among others, homoscedascity (homogeniety, equality of variances). Procedure is quite simple for One-Way ANOVA: bartlett.test(x ~ g) # where x is numeric, and g is a factor var.test(x ~ g) But, for 2x2 tables, i.e. Two-Way ANOVA's, I want to do something like this: bartlett.test(x ~ c(g1, g2)) # or with list; see latter: var.test(x ~ list(g1, g2)) Of course, ANOVA assumptions can be checked with graphical procedures, but what about "an arithmetic option"? Is that, at all, manageable? How do you test homoscedascity in Two-Way ANOVA?

  • Differences between AForge and OpenCV

    - by vrish88
    Hello, I am just learning about computer vision and C#. It seems like two prominent image processing libraries are OpenCV and AForge. What are some of the differences of the two? I am making a basic image editor in C# and while researching I have come across articles on both. But I don't really know why I would choose one over the other. I would like to eventually improve the app to include more advanced functions. Thanks.

  • De-dupe a list of hundreds of thousands of first name/last name/address/date of birth

    - by Darren
    I have a large data set which I know contains many dupicate records. Basically I have data on first name, last name, different address components and date of birth. I think the best way to do this is to use the name and date of birth as chances are if these things match, it's the same person. There are probably lots of instances where there are slight differences in spelling (like typos missing a single letter) or use of name (ie: some might have a middle initial in first name column) which would be good to account for, but I'm not sure how to approach this. Are there any tools or articles on going about this process? The data is all in a MySQL database and I have a basic proficiency in SQL.

  • Tree View WIKI replacement solution for SharePoint like Confluence?

    - by Melih Öztürk
    Hi to all, I keep my Process Documents on SVN and I want to create a Wiki page includes the information about these files. We use SharePoint in the company for basic document sharing and team sites. As it is mentioned in http://stackoverflow.com/questions/256407/what-are-your-biggest-complaints-about-sharepoint SharePoint Wiki lacks of usability. I need an easy to use wiki tool which is capable of showing the content like WikiPedia contents and it would be great if I could have the SharePoint tree view and Active Directory authentication also. I googled it and found Atlassian's Confluence and it seems that this product is capable of the requirements. We use Jira for issue tracking, so we can use it's reporting in dashboards. I need and it has a Wiki part which displays wiki pages in tree view. It should be like Does anyone used Confluence or have an idea for other products which meets my requirements

  • Best Practise for Writing a POS System

    - by Gary
    Hi, I'm putting together a basic POS system in C# that needs to print to a receipt printer and open a cash drawer. Do I have to use the Microsoft Point of Service SDK? I've been playing around with printing to my Samsung printer using the Windows driver that came with it, and it seems to work great. I assume though that other printers may not come with Windows drivers and then I would be stuck? Or would I be able to simply use the Generic/Text Driver to print to any printer that supports it? For the cash drawer I would need to send codes directly to the COM port which is fine with me, if it saves me the hassle of helping clients setup OPOS drivers on there systems. Am I going down the wrong path here? Thanks, Gary
