  • Merging list problem

    - by Martin Malmstrøm
    Sorry about the bad heading, but the question was not easy to compress into one sentence... I have two lists of contigs (list1 and list2). They contain mostly unique contigs, but with some overlap. I want to compare list1 and list2 and then create a list3 that contains all contigs in list1 minus those also present in list2. Is this possible with a simple cat/paste/grep/sort/uniq kind of batch command? Thanks!

  • Maximum number of inodes in a directory?

    - by Dr. UNIX
    Is there a maximum number of inodes in a single directory? I have a directory of 2 million+ files and can't get an the ls command to work against that directory. So now I'm wondering if I've exceeded a limit on inodes in Linux. Is there a limit before a 2^64 numerical limit?

    - by SCM
    Hi I have an issue in VSS 2005, there is a project in VSS, having multiple folders files in it, and most of the files around 2000 having their property "Store only latest version" is checked. I don't know how it is set. I want to change those around 2000 files property "Store only latest version" to unchecked, so that VSS retain all those files previous version. can it be done through a single command to unchecked this option for all those files in project recursively? Thanks

  • Java execution details in System.out

    - by John
    As I remember there is a magic command line option in Java that turn on writing of operations that are currently executed to console. The output was looked like byte code. I do not mean -verbose, because it prints only class loading, while this option outputs information like memory allocation etc.

  • How can I extract a range of lines from a text file on unix?

    - by Adam J. Forster
    I have a ~23000 line sql dump containing several databases worth of data. I need to extract a certain section of this file (i.e. the data for a single database) and place it in a new file. I know both the start and end line numbers of the data that I want. Does anyone know a unix command (or series of commands) to extract all lines from a file between say line 16224 and 16482 and then redirect them into a new file?

  • MVVM pattern and nested view models - communication and lookup lists

    - by LostInWPF
    I am using Prism for a new application that I am creating. There are several lookup lists that will be used in several places in the application. Therefore it makes sense to define it once and use that everywhere I need that functionality. My current solution is to use typed data templates to render the controls inside a content control. <DataTemplate DataType={x:Type ListOfCountriesViewModel}> <ComboBox ItemsSource={Binding Countries} SelectedItem="{Binding SelectedCountry"/> </DataTemplate> <DataTemplate DataType={x:Type ListOfRegionsViewModel}> <ComboBox ItemsSource={Binding Countries} SelectedItem={Binding SelectedRegion} /> </DataTemplate> public class ParentViewModel { SelectedCountry get; set; SelectedRegion get; set; ListOfCountriesViewModel CountriesVM; ListOfRegionsViewModel RgnsVM; } Then in my window I have 2 content controls and the rest of the controls <ContentControl Content="{Binding CountriesVM}"></ContentControl> <ContentControl Content="{Binding RgnsVM}"></ContentControl> <Rest of controls on view> At the moment I have this working and the SelectedItems for the combo boxes are publising events via EventAggregator from the child view models which are then subscribed to in the parent view model. I am not sure that this is the best way to go as I can imagine I would end up with a lot of events very quickly and it will become unwieldy. Also if I was to use the same view model on another window it will publish the event and this parent viewmodel is subscribed to it which could have unintended consequences. My questions are :- Is this the best way to put lookup lists in a view which can be re-used across screens? How do I make it so that the combobox which is bound to the child viewmodel sets the relevant property on the parent viewmodel without using events / mediator. e.g in this case SelectedCountry for example? Any alternative implementation proposals for what I am trying to do? I have a feeling I am missing something obvious and there is so much info it is hard to know what is right so any help would be most gratefully received.

  • Strong Naming an assembly using command line compile

    - by David
    I am trying to use NAnt in order to compile and sign an assembly using the vbc compiler. I have a project set up and am able to successfully sign the assembly compiling with VS2010. When I try to sign it using the command line I get this error: vbc : error BC30140: Error creating assembly manifest: Error signing assembly -- The parameter is incorrect. I even created a trivially simple app (just an assemblyinfo.vb file) that will not compile and sign using vbc.exe What am I doing wrong? here is my assemblyinfo.vb: Option Strict Off Option Explicit On Imports System Imports System.Reflection <Assembly: AssemblyVersionAttribute("2010.05.18.0918"), _ Assembly: AssemblyCopyrightAttribute("Copyright © Patient First 2007"), _ Assembly: AssemblyCompanyAttribute("Patient First, Inc."), _ Assembly: AssemblyProductAttribute("Patient First Framework"), _ Assembly: AssemblyDelaySign(false), _ Assembly: AssemblyKeyFile("test.pfx"), _ Assembly: AssemblyTitleAttribute("PatientFirst.Framework")> test.pfx is located in the same folder as assemblyinfo.vb Here is how I am trying to compile it: vbc /target:library /verbose assemblyinfo.vb I also tried using vbc /target:library /verbose assemblyinfo.vb /keyfile:test.pfx and tried using /keyfile parameter without the AssemblyDelaySign and AssemblyKeyFile attributes If I remove the AssemblyDelaySign and AssemblyKeyFile attributes and leave off the /keyfile command line parameter it compiles fine. What is the correct way to do this with vbc? --EDIT: I have found that MSBuild also does not like having the AssemblyKeyFile attribute as I have defined it in the AssemblyInfo.vb, it gives the same failure message. So the only way I can currently get this to build correctly is to set properties on the project to tell it which key file to use and to sign the assembly.

  • Question on MVVM pattern on WPF ?

    - by Ashish Ashu
    I have a user control let say UC1 . This user control have viewmodel UC1_vm. In the usercontrol UC1 I have a canvas in which drawing curve logic is implemented. This drawing curve logic is based on the data points property in the view model ( UC1_vm). The data points property inside the view model change with different condition. The generation of data points is written in the View Model. I want to bind the data points property in the view model to the draw curve logic inside the User control (view). I want whenever the data point property is changed in the view model , the canvas calls the draw curve method. Can I set the set any property of canvas which when changed it calls the on paint logic auto matically? Please suggest me the approach of implementing this scenario!!

  • Page navigation in silverlight 4 using MVVM pattern

    - by Archie
    Hello, I have a a navigation application developed in Silverlight 4. It has a main page which contains a frame. I load a particualr view in that frame and I know that I can use NavigationService to navigate to other page which would be loaded in the same frame. But my question is how it can be done using MVVM? To get the frame do I need to pass the reference of the page? Also, as per my knowledge one view is not aware of any other views. So what is the best way to make them aware of each other? I have heard of Controller and Mediator but how shall I implement them so as to get the Frame of the mainpage? It would be very helpful if anyone can give me the example or probably sample code for this. Thanks in advance.

I have three more usercontrols that is inside the usercontrol UC ( discussed above). Let's say uc1, uc2 and uc3. and the visibility of uc1 , uc2 and uc3 inside UC depends on the type selected ( which ever radio button is selected ). Since UC is binded to UCViewModel and I have to do all the stuff related to uc1 , uc2 and uc3 inside UCViewModel. Can I have seperate VM to uc1 , uc2 and uc3.. if Yes how can i do that ? Please Help!!

  • Repository pattern with lazying loading using POCO

    - by Simon G
    Hi, I'm in the process of starting a new project and creating the business objects and data access etc. I'm just using plain old clr objects rather than any orms. I've created two class libraries: 1) Business Objects - holds all my business objects, all this objects are light weight with only properties and business rules. 2) Repository - this is for all my data access. The majority of my objects will have child list in and my question is what is the best way to lazy load these values as I don't want to bring back unnecessary information if I dont need to. I've thought about when using the "get" on the child property to check if its "null" and if it is call my repository to get the child information. This has two problems from what I can see: 1) The object "knows" how to get itself I would rather no data access logic be held in the object. 2) This required both classes to reference each other which in visual studio throws a circular dependency error. Does anyone have any suggestions on how to overcome this issue or any recommendations on my projects layout and where it can be improved? Thanks

  • CreateProcess doesn't pass command line arguments

    - by mnh
    Hello I have the following code but it isn't working as expected, can't figure out what the problem is. Basically, I'm executing a process (a .NET process) and passing it command line arguments, it is executed successfully by CreateProcess() but CreateProcess() isn't passing the command line arguments What am I doing wrong here?? int main(int argc, char* argv[]) { PROCESS_INFORMATION ProcessInfo; //This is what we get as an [out] parameter STARTUPINFO StartupInfo; //This is an [in] parameter ZeroMemory(&StartupInfo, sizeof(StartupInfo)); StartupInfo.cb = sizeof StartupInfo ; //Only compulsory field LPTSTR cmdArgs = "[email protected]"; if(CreateProcess("D:\\email\\smtp.exe", cmdArgs, NULL,NULL,FALSE,0,NULL, NULL,&StartupInfo,&ProcessInfo)) { WaitForSingleObject(ProcessInfo.hProcess,INFINITE); CloseHandle(ProcessInfo.hThread); CloseHandle(ProcessInfo.hProcess); printf("Yohoo!"); } else { printf("The process could not be started..."); } return 0; } EDIT: Hey one more thing, if I pass my cmdArgs like this: // a space as the first character LPTSTR cmdArgs = " [email protected]"; Then I get the error, then CreateProcess returns TRUE but my target process isn't executed. Object reference not set to an instance of an object

  • Android ndk-build command does nothing

    - by James
    I have a similar question to that posted here: Android NDK: why ndk-build doesn't generate .so file and a new libs folder in Eclipse? ...though I am running Windows 7, not Mac os. Essentially the ndk-build command is run, gives no error but doesn't create an .so file (also, since I'm on windows this should create a .dll and not an .so?). I tried running the command from the root, jni, src folders etc. but got the same result; cmd just returns to the prompter after a few seconds. I ran it again from the jni folder with NDK_LOG=1 parameter to see what was happening. Here is a portion of the transcript of the log results after running ndk-build in the jni folder (after it successfully identified the platform, etc.)...

  • Extract known pattern substring from NSString (without regex)

    - by d11wtq
    I'm really tempted to drop RegexKit (or my own libpcre wrapper) into my project in order to do this, but before I do that I want to know how Cocoa developers manage to do half of this basic stuff without really convoluted code or without linking with RegexKit or another regular expression library. I find it gobsmacking that Cocoa does not include any regular expression matching features. I've so accustomed to using regular expressions for all kinds of things that I'm lost without them. I can do what I need without them, but the code would be rather convoluted. So, Cocoa devs, I ask you, what's the "Cocoa way" to do this... The problem is an everyday problem in programming as far as I'm concerned. Cocoa must have ways of doing this with the built-in features. Note that the position of the elements I want to match changes, and sometimes "quotes" are present. Whitespace is variable. Take the following strings: Content-Type: application/xml; charset=utf-8 Content-Type: text/html; charset="iso-8859-1" Content-Type: text/plain; charset=us-ascii Content-Type: text/plain; name="example.txt"; charset=utf-8 From all of these strings, how would you go about determining the mime type (e.g. text/plain) and the charset (e.g. utf-8) using just the built-in Cocoa classes? I'd end up performing a series of -rangeOfString: and substring calls, with conditional checks to deal with the optional quotes etc. Is there a way to do this with NSScanner? The NSScanner class seems to have a pretty naive API to me. Something like C's sscanf() that works for NSString objects would be an ideal fit. Most of my string parsing needs are simple such as this example so maybe regular expressions, while I'm accustomed to them, are overkill?

  • My SqlComand on SSIS - DataFlow OLE DB Command seems not works

    - by Angel Escobedo
    Hello Im using OLE DB Source for get rows from a dBase IV file and it works, then I split the data and perform a group by with aggregate component. So I obtain a row with two columns with "null" value : CompanyID | CompanyName | SubTotal | Tax | TotalRevenue Null Null 145487 27642.53 173129.53 this success because all rows have been grouped with out taking care about the firsts columns and just Summing the valuable columns, so I need to change that null for default values as CompanyID = "100000000" and CompanyName = "Others". I try use SqlCommand on a OLE DB Command Component : SELECT "10000000" AS RUCCLI , "Otros - Varios" AS RAZCLI FROM RGVCAFAC <property id="1505" name="SqlCommand" dataType="System.String" state="default" isArray="false" description="The SQL command to be executed." typeConverter="" UITypeEditor="Microsoft.DataTransformationServices.Controls.ModalMultilineStringEditor, Microsoft.DataTransformationServices.Controls, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" containsID="false" expressionType="Notify">SELECT "10000000" AS RUCCLI , "Otros - Varios" AS RAZCLI FROM RGVCAFAC</property> but nothings happens, why? and finally the task finish when the data is inserted on a SQL Server Table.
