  • property names are different from original Object in the silverlight

    - by kwon
    Following is part of service layer which is provided by WCF service : [Serializable] public class WaitInfo { private string roomName; private string pName; private string tagNo; public string RoomName { get { return roomName; } set { this.roomName = value; } } public string PName { get { return pName; } set { this.pName = value; } } public string TagNo { get { return tagNo; } set { this.tagNo = value; } } } public class Service1 : IService1 { public List<WaitInfo> GetWaitingList() { MyDBDataContext db = new MyDBDataContext(); var query = from w in db.WAIT_INFOs select new WaitInfo { TagNo = w.PATIENT_INFO.TAG_NO, RoomName= w.ROOM_INFO.ROOM_NAME, PName= w.PATIENT_INFO.P_NAME }; List<WaitInfo> result = query.ToList(); return result; } And following is codebehind part of UI layer which is provided by Silverlight public MainPage() { InitializeComponent(); Service1Client s = new Service1Client(); s.GetWaitingListCompleted += new EventHandler<GetWaitingListByCompletedEventArgs>( s_GetWaitingListCompleted); s.GetWaitingListAsync(); } void s_GetWaitingListCompleted(object sender, RadControlsSilverlightApplication1.ServiceReference2.GetWaitingListByCompletedEventArgs e) { GridDataGrid.ItemsSource = e.Result; } And following is xaml code in Silverlight page <Grid x:Name="LayoutRoot"> <data:DataGrid x:Name="GridDataGrid"></data:DataGrid> </Grid> Is is very simple code, however what I am thinking weird is property name of object at "e.Result" in the code behind page. In the service layer, although properties' names are surely "RoomName, PName, TagNo", in the silverlight properties' names are "roomName, pName, tagNo" which are private variable name of the WaitingList Object. Did I something wrong? Thanks in advance.

  • Generic Singleton Façade design pattern

    - by Paul
    Hi I try write singleton façade pattern with generics. I have one problem, how can I call method from generic variable. Something like this: T1 t1 = new T1(); //call method from t1 t1.Method(); In method SingletonFasadeMethod I have compile error: Error 1 'T1' does not contain a definition for 'Method' and no extension method 'Method' accepting a first argument of type 'T1' could be found (are you missing a using directive or an assembly reference?) Any advace? Thank, I am beginner in C#. All code is here: namespace GenericSingletonFasade { public interface IMyInterface { string Method(); } internal class ClassA : IMyInterface { public string Method() { return " Calling MethodA "; } } internal class ClassB : IMyInterface { public string Method() { return " Calling MethodB "; } } internal class ClassC : IMyInterface { public string Method() { return "Calling MethodC"; } } internal class ClassD : IMyInterface { public string Method() { return "Calling MethodD"; } } public class SingletonFasade<T1,T2,T3> where T1 : class,new() where T2 : class,new() where T3 : class,new() { private static T1 t1; private static T2 t2; private static T3 t3; private SingletonFasade() { t1 = new T1(); t2 = new T2(); t3 = new T3(); } class SingletonCreator { static SingletonCreator() { } internal static readonly SingletonFasade<T1,T2,T3> uniqueInstace = new SingletonFasade<T1,T2,T3>(); } public static SingletonFasade<T1,T2,T3> UniqueInstace { get { return SingletonCreator.uniqueInstace; } } public string SingletonFasadeMethod() { //Problem is here return t1.Method() + t2.Method() + t3.Method(); } } } I use this for my problem. public class SingletonFasade<T1, T2, T3> where T1 : class, IMyInterface, new() where T2 : class, IMyInterface, new() where T3 : class, IMyInterface, new() {//...} Is any solution without Interfaces ??

    I am trying to check a field in some XML that is returned from an outside.

  • Why does C++ not allow multiple types in one auto statement?

    - by Walter
    The 2011 C++ standard introduced the new keyword auto, which can be used for defining variables instead of a type, i.e. auto p=make_pair(1,2.5); // pair<int,double> auto i=std::begin(c), end=std::end(c); // decltype(std::begin(c)) In the second line, i and end are of the same type, referred to as auto. The standard does not allow auto i=std::begin(container), e=std::end(container), x=*i; when x would be of different type. My question: why does the standard not allow this last line? It could be allowed by interpreting auto not as representing some to-be-decuded type, but as indicating that the type of any variable declared auto shall be deduced from its assigned value. Is there any good reason for the C++11 standard to not follow this approach? There is actually a use case for this, namely in the initialisation statement of for loops: for(auto i=std::begin(c), end=std::end(c), x=*i; i!=end; ++i, x+=*i) { ... } when the scope of the variables i, end, and x is limited to the for loop. AFAIK, this cannot be achieved in C++ unless those variables have a common type. Is this correct? (ugly tricks of putting all types inside a struct excluded) There may also be use cases in some variadic template applications.

  • class header+ implementation

    - by igor
    what am I doing wrong here? I keep on getting a compilation error when I try to run this in codelab (turings craft) Instructions: Write the implementation (.cpp file) of the GasTank class of the previous exercise. The full specification of the class is: A data member named amount of type double. A constructor that no parameters. The constructor initializes the data member amount to 0. A function named addGas that accepts a parameter of type double . The value of the amount instance variable is increased by the value of the parameter. A function named useGas that accepts a parameter of type double . The value of the amount data member is decreased by the value of the parameter. A function named getGasLevel that accepts no parameters. getGasLevel returns the value of the amount data member. class GasTank{ double amount; GasTank(); void addGas(double); void useGas(double); double getGasLevel();}; GasTank::GasTank(){ amount=0;} double GasTank::addGas(double a){ amount+=a;} double GasTank::useGas(double a){ amount+=a;} double GasTank::getGasLevel(){ return amount;}

  • Java generic Comparable where subclasses can't compare to eachother

    - by dege
    public abstract class MyAbs implements Comparable<MyAbs> This would work but then I would be able to compare class A and B with each other if they both extend MyAbs. What I want to accomplish however is the exact opposite. So does anyone know a way to get the generic type to be the own class? Seemed like such a simple thing at first... Edit: To explain it a little further with an example. Say you have an abstract class animals, then you extend it with Dogs and ants. I wouldn't want to compare ants with Dogs but I however would want to compare one dog with another. The dog might have a variable saying what color it is and that is what I want to use in the compareTo method. However when it comes to ants I would rather want to compare ant's size than their color. Hope that clears it up. Could possibly be a design flaw however.

  • When do instance variables get initialized and values assigned?

    - by AKh
    When doees the instance variable get initialized? Is it after the constructor block is done or before it? Consider this example: public abstract class Parent { public Parent(){ System.out.println("Parent Constructor"); init(); } public void init(){ System.out.println("parent Init()"); } } public class Child extends Parent { private Integer attribute1; private Integer attribute2 = null; public Child(){ super(); System.out.println("Child Constructor"); } public void init(){ System.out.println("Child init()"); super.init(); attribute1 = new Integer(100); attribute2 = new Integer(200); } public void print(){ System.out.println("attribute 1 : " +attribute1); System.out.println("attribute 2 : " +attribute2); } } public class Tester { public static void main(String[] args) { Parent c = new Child(); ((Child)c).print(); } } OUTPUT: Parent Constructor Child init() parent Init() Child Constructor attribute 1 : 100 attribute 2 : null When the memory for the atribute 1 & 2 are allocated in the heap ? Curious to know why is attribute 2 is NULL ? Are there any design flaws?

  • Wait on multiple condition variables on Linux without unnecessary sleeps?

    - by Joseph Garvin
    I'm writing a latency sensitive app that in effect wants to wait on multiple condition variables at once. I've read before of several ways to get this functionality on Linux (apparently this is builtin on Windows), but none of them seem suitable for my app. The methods I know of are: Have one thread wait on each of the condition variables you want to wait on, which when woken will signal a single condition variable which you wait on instead. Cycling through multiple condition variables with a timed wait. Writing dummy bytes to files or pipes instead, and polling on those. #1 & #2 are unsuitable because they cause unnecessary sleeping. With #1, you have to wait for the dummy thread to wake up, then signal the real thread, then for the real thread to wake up, instead of the real thread just waking up to begin with -- the extra scheduler quantum spent on this actually matters for my app, and I'd prefer not to have to use a full fledged RTOS. #2 is even worse, you potentially spend N * timeout time asleep, or your timeout will be 0 in which case you never sleep (endlessly burning CPU and starving other threads is also bad). For #3, pipes are problematic because if the thread being 'signaled' is busy or even crashes (I'm in fact dealing with separate process rather than threads -- the mutexes and conditions would be stored in shared memory), then the writing thread will be stuck because the pipe's buffer will be full, as will any other clients. Files are problematic because you'd be growing it endlessly the longer the app ran. Is there a better way to do this? Curious for answers appropriate for Solaris as well.

  • confusing fork system call

    - by benjamin button
    Hi, i was just checking the behaviour of fork system call and i found it very confusing. i saw in a website that Unix will make an exact copy of the parent's address space and give it to the child. Therefore, the parent and child processes have separate address spaces #include <stdio.h> #include <sys/types.h> int main(void) { pid_t pid; char y='Y'; char *ptr; ptr=&y; pid = fork(); if (pid == 0) { y='Z'; printf(" *** Child process ***\n"); printf(" Address is %p\n",ptr); printf(" char value is %c\n",y); sleep(5); } else { sleep(5); printf("\n ***parent process ***\n",&y); printf(" Address is %p\n",ptr); printf(" char value is %c\n",y); } } the output of the above program is : *** Child process *** Address is 69002894 char value is Z ***parent process *** Address is 69002894 char value is Y so from the above mentioned statement it seems that child and parent have separet address spaces.this is the reason why char value is printed separately and why am i seeing the address of the variable as same in both child and parent processes.? Please help me understand this!

  • ViewController access data

    - by Giovanni Filaferro
    Today i would ask you if there is a way to call a method of another view controller just not initializing it or just how to get that viewController as a global variable declared in .h file. Help me please. I'm using a PageViewController and I have to use a method of the contentViewController alredy initialized. here I create my ViewControllers: - (void)createTheContent { NSLog(@"createTheContent"); pageController = nil; //[pageController removeFromParentViewController]; //[pageController awakeFromNib]; NSDictionary *options = [NSDictionary dictionaryWithObject:[NSNumber numberWithInteger:UIPageViewControllerSpineLocationMin] forKey: UIPageViewControllerOptionSpineLocationKey]; self.pageController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStylePageCurl navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options: options]; pageController.dataSource = self; [[pageController view] setFrame:CGRectMake(0, 0, 320, 365)]; initialViewController = [self viewControllerAtIndex:0]; NSMutableArray *viewControllers = [NSArray arrayWithObject:initialViewController]; [pageController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil]; [self addChildViewController:pageController]; [[self view] addSubview:[pageController view]]; [pageController didMoveToParentViewController:self]; } here are my propertys in .h file: contentViewController *initialViewController; } //Page View Controller Properties @property (strong, nonatomic) UIPageViewController *pageController; @property (strong, nonatomic) NSArray *pageContent; @property (strong, nonatomic) NSMutableArray *pageStrings; @property (strong, nonatomic) id dataObject;

  • Rotate MapView in Android

    - by Matthew B.
    I am writing an Android app where one of the features is that the map will rotate according to the compass (i.e. if the phone is pointing east, the map will be oriented so that the east side of the map is on top). Previous answers that I have found suggested over writing the onDraw() method in mapView, however, the api changed the method to final so it cannot be overwritten. As a result I have tried to overwrite the dispatchDraw() method like so: Note: -compass is a boolean that if true, rotate the view -bearing is a float variable that has the degrees that the view should rotate protected void dispatchDraw(Canvas canvas) { canvas.save(); if (compass) { final float w = this.getWidth(); final float h = this.getHeight(); final float scaleFactor = (float)(Math.sqrt(h * h + w * w) / Math.min(w, h)); final float centerX = w / 2.0f; final float centerY = h / 2.0f; canvas.rotate(bearing, centerX, centerY); canvas.scale(scaleFactor, scaleFactor, centerX, centerY); } super.dispatchDraw(canvas); canvas.restore(); }

  • VS2010 Implement Generic Interface expansion doesn't use specified type

    - by TJB
    Using the release version of Visual Studio 2010 I think there's a difference in the "Implement Interface" expansion from VS2008 If I speicify an interface and implement it in a class as so: public interface IRepository<T> where T : IModel { T Get<T>(int id); void Update<T>(); int Add<T>(T item); } public class MockRepository : IRepository<MockUser> { // ... } Then use the "Implement Interface" expansion and get this: public class MockRepository : IRepository<MockUser> { public T Get<T>(int id) { throw new NotImplementedException(); } public void Update<T>() { throw new NotImplementedException(); } public int Add<T>(T item) { throw new NotImplementedException(); } } Instead of what I expected public class MockRepository : IRepository<MockUser> { public MockUser Get<MockUser>(int id) { throw new NotImplementedException(); } public void Update<MockUser>() { throw new NotImplementedException(); } public int Add<MockUser>(MockUser item) { throw new NotImplementedException(); } } The IDE uses the type variable name from the generic interface definition T instead of the specified concrete type MockUser. Is this a bug? Or is something new just for VS2010 / .Net 4.0?

  • Why jquery ajax calls fails after session timeout in asp.net mvc?

    - by Pandiya Chendur
    when there is a value in my session variable my ajax calls work properly... But when a session is timedout it doesn't seem to work returning empty json result.... public JsonResult GetClients(int currentPage, int pageSize) { if (Session["userId"]!=null) { var clients = clirep.FindAllClients(Convert.ToInt32(Session["userId"])).AsQueryable(); var count = clients.Count(); var results = new PagedList<ClientBO>(clients, currentPage - 1, pageSize); var genericResult = new { Count = count, Results = results ,isRedirect=false}; return Json(genericResult); } else { var genericResult = new {redirectUrl = Url.Action("Create", "Registration"), isRedirect = true }; return Json(genericResult); } } However else part does'nt seem to work.... success: function(data) { alert(data.Results); if (data.isRedirect) { window.location.href = data.redirectUrl; } } EDIT: My global.asax has this, public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Clients", "Clients/{action}/{id}", new { controller = "Clients", action = "Index", id = "" } ); routes.MapRoute( "Registrations", "{controller}/{action}/{id}", new { controller = "Registration", action = "Create", id = "" } ); }

  • Binary files printing and desired precision

    - by yCalleecharan
    Hi, I'm printing a variable say z1 which is a 1-D array containing floating point numbers to a text file so that I can import into Matlab or GNUPlot for plotting. I've heard that binary files (.dat) are smaller than .txt files. The definition that I currently use for printing to a .txt file is: void create_out_file(const char *file_name, const long double *z1, size_t z_size){ FILE *out; size_t i; if((out = _fsopen(file_name, "w+", _SH_DENYWR)) == NULL){ fprintf(stderr, "***> Open error on output file %s", file_name); exit(-1); } for(i = 0; i < z_size; i++) fprintf(out, "%.16Le\n", z1[i]); fclose(out); } I have three questions: Are binary files really more compact than text files?; If yes, I would like to know how to modify the above code so that I can print the values of the array z1 to a binary file. I've read that fprintf has to be replaced with fwrite. My output file say dodo.dat should contain the values of array z1 with one floating number per line. I have %.16Le up in my code but I think that %.15Le is right as I have 15 precision digits with long double. I have put a dot (.) in the width position as I believe that this allows expansion to an arbitrary field to hold the desired number. Am I right? As an example with %.16Le, I can have an output like 1.0047914240730432e-002 which gives me 16 precision digits and the width of the field has the right width to display the number correctly. Is placing a dot (.) in the width position instead of a width value a good practice? Thanks a lot...

  • How can I set up an editor to work with Git on Windows?

    - by Patrick McElhaney
    I'm trying out Git on Windows. I got to the point of trying "git commit" and I got this error: Terminal is dumb but no VISUAL nor EDITOR defined. Please supply the message using either -m or -F option. So I figured out I need to have an environment variable called EDITOR. No problem. I set it to point to Notepad. That worked, almost. The default commit message opens in Notepad. But Notepad doesn't support bare line feeds. I went out and got Notepad++. But I can't figure out how to get Notepad++ set up as the %EDITOR% in such a way that it works with Git as expected. I'm not married to Notepad++. At this point I couldn't care less what editor I use. I just want to be able to type my commit messages without using -m. So, for those of you using Git on Windows: What (free) tool do you use to edit your commit message, and what do you get when you type echo %EDITOR% at the command prompt?

  • Iterating XML nodes using VBA

    - by ydobonmai
    Note:- It just might be a iterating XML nodes using VBA question. Please look at the bottom of this question. It would be good If we can iterate without using MSXML2.DOMDocument I see the this question which answers part of my question on how to retrieve the CustomXMLPart. However, I am not able to iterate through the Xml. That way, this might not be specific to CustomXmlPart, It just might be a iterating XML using VBA question. Following is the XML I have in my CustomXMLPart. <Items> <Item1>Item1</Item1> <Item2>Item2</Item2> <Item3>Item3</Item3> </Items> This is how I add the above XML as CustomXmlPart:- static void AddCustomTableXmlPart(WordprocessingDocument document) { MainDocumentPart mainDocumentPart = document.MainDocumentPart; XDocument itemXml = GetItemsAsCustomXML(); if (mainDocumentPart.GetPartsCountOfType<CustomXmlPart>() > 0) mainDocumentPart.DeleteParts<CustomXmlPart>(mainDocumentPart.CustomXmlParts); //Add a new customXML part and then add content var customXmlPart = mainDocumentPart.AddCustomXmlPart(CustomXmlPartType.CustomXml); //copy the XML into the new part... using (var ts = new StreamWriter(customXmlPart.GetStream())) { ts.Write(itemXml.ToString()); ts.Flush(); } } and this is how I am accessing it in the macro:- Dim itemNode As xmlNode Dim itemChildren As XMLNodes ' The below line throws a run-time error 'Run-time error '13' - 'type mismatch ' not sure why. **Set itemChildren= ActiveDocument.CustomXMLParts(ActiveDocument.CustomXMLParts.Count).SelectSingleNode("//Items").ChildNodes** Interestingly, when I quick watch ActiveDocument.CustomXMLParts(ActiveDocument.CustomXMLParts.Count).SelectSingleNode("//Items").ChildNodes, I see child items in the quick watch window. Is the assignment to the itemChildren variable incorrect? I want to iterate through all the items and get get text for all of them. Could anybody help?

  • Performing calculations by subsets of data in R

    - by Vivi
    I want to perform calculations for each company number in the column PERMNO of my data frame, the summary of which can be seen here: > summary(companydataRETS) PERMNO RET Min. :10000 Min. :-0.971698 1st Qu.:32716 1st Qu.:-0.011905 Median :61735 Median : 0.000000 Mean :56788 Mean : 0.000799 3rd Qu.:80280 3rd Qu.: 0.010989 Max. :93436 Max. :19.000000 My solution so far was to create a variable with all possible company numbers compns <- companydataRETS[!duplicated(companydataRETS[,"PERMNO"]),"PERMNO"] And then use a foreach loop using parallel computing which calls my function get.rho() which in turn perform the desired calculations rhos <- foreach (i=1:length(compns), .combine=rbind) %dopar% get.rho(subset(companydataRETS[,"RET"],companydataRETS$PERMNO == compns[i])) I tested it for a subset of my data and it all works. The problem is that I have 72 million observations, and even after leaving the computer working overnight, it still didn't finish. I am new in R, so I imagine my code structure can be improved upon and there is a better (quicker, less computationally intensive) way to perform this same task (perhaps using apply or with, both of which I don't understand). Any suggestions?

Here's my code: = subscription.input :plan_type_id, :as => :radio, :label => false, :wrapper_html => {:class => "plan_type"}, :collection => { @plans[:premium_yearly][:description]+number_to_currency(@plans[:premium_yearly][:amount], :precision => 2) => @plans[:premium_yearly][:value], @plans[:premium_monthly][:description]+number_to_currency(@plans[:premium_monthly][:amount], :precision => 2) => @plans[:premium_monthly][:value] } Has you may may see, I build the label I want to show with my @plans variable and the :collection attribute. Is there any way I can modify the way it renders the label, I want to put some css to some part of the label. I want something like this: = subscription.input :plan_type_id, :as => :radio, :label => false, :wrapper_html => {:class => "plan_type"}, :collection => { @plans[:premium_yearly][:description]+'<b>'+number_to_currency(@plans[:premium_yearly][:amount], :precision => 2)+'<\\b>' => @plans[:premium_yearly][:value], @plans[:premium_monthly][:description]+'<b>'+number_to_currency(@plans[:premium_monthly][:amount], :precision => 2)+'<\\b>' => @plans[:premium_monthly][:value] } Thanks in advanced.

  • Problems compiling libjingle/gtk+-2.0 for Mac OS X

    Hi All, I'm trying to compile libjingle on Mac OSX Snow Leopard. The INSTALL file said to './configure', 'make' and 'make install', as usual. But make fails for me. Initially it gave some messages indicating that I didn't have pkg-config installed (I guess OSX doesn't come with it installed?), so I downloaded pkg-config from http://pkgconfig.freedesktop.org/releases/ Now I get this message: Package gtk+-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `gtk+-2.0.pc' to the PKG_CONFIG_PATH environment variable No package 'gtk+-2.0' found I tried to install gtk by using the script at SourceForge: http://sourceforge.net/projects/gtk-osx/ (this is the website pointed to by the gtk website) Running the script didn't really seem to do anything, here is the output: $./gtk-osx-build-setup.sh Checking out jhbuild (2.27.3) from git...

The problem at the moment is if the user logs into the site, then does nothing and the session times out, I have no way that I can think of to redirect the parent of the window to the login screen when the user opens it. So far I have tried using cflocation but that has no way of specifying the container that should be redirected (i.e. the page in the window is being redirected but not the windows parent). I have also thought about using a hidden input with a value based on the session which is then check with Body onLoad event but currently this doesnt work with how the pages have been setup. The last option I have is to check the session variable on loading the window and then closing it if the user is not logged in, which will cause the parent to refresh and redirect to login anyway. However I cant find a way to close a cfwindow without using javascript. Thanks for any help you can give.

  • Is it possible to accept a button tag to be in some range iphone sdk

    - by neha
    Hi all, In my application I'm doing dynamic resizing of cells and label in it depending upon the text in it. I'm adding button to cells in uitableview. I'm taking the label instance and button instance in a new label and button variable respectively and setting their frames to arrange them properly after resizing. if(cel==nil) { //some code original_label=[[UILabel alloc]init]; original_label.tag=111; //SOME MORE CODE GOES HERE original_button=[[UIButton alloc]init]; original_button.tag=222; //SOME MORE CODE GOES HERE } new_label=(UILabel *) [cell viewWithTag:111]; //This' how I'm taking the label instance on cell and below button instance on cell in new variables new_button = (UIButton * ) [cell viewWithTag:222]; Earlier I kept the tags of all the buttons on cells same, so it was easier to get button instances on cells properly and were being arranged properly. But now I want to recognize these buttons separately as I'm adding some functionality on button_click. I'm giving the buttons that are added to the cells incremental tags[1,2,3...9 and so on]. Now, how can I take these button tags in some range like[suppose 1-9]? Can anybody help? Thanks in advance.

  • Action Mailer: How do I render dynamic data in an email body that is stored in the database?

    - by Brandon Toone
    I have Action Mailer setup to render an email using the body attribute of my Email model (in the database). I want to be able to use erb in the body but I can't figure out how to get it to render in the sent email message. I'm able to get the body as a string with this code # models/user_mailer.rb def custom_email(user, email_id) email = Email.find(email_id) recipients user.email from "Mail It Example <[email protected]>" subject "Hello From Mail It" sent_on Time.now # pulls the email body and passes a string to the template views/user_mailer/customer_email.text.html.erb body :msg => email.body end I came across this article http://rails-nutshell.labs.oreilly.com/ch05.html which says I can use render but I'm only able to get render :text to work and not render :inline # models/user_mailer.rb def custom_email(user, email_id) email = Email.find(email_id) recipients user.email from "Mail It Example <[email protected]>" subject "Hello From Mail It" sent_on Time.now # body :msg => email.body body :msg => (render :text => "Thanks for your order") # renders text and passes as a variable to the template # body :msg => (render :inline => "We shipped <%= Time.now %>") # throws a NoMethodError end

  • trying to read a delimited text file from resources - but it wont run

    - by Bigfatty
    I'm having a problem where instead of reading a text file from the location string, I changed it to read the text file from the resource location and it messes up my program. I've also used the insert snippet method to get most of this code, so it is safe to say I don't know what is going on. Could some one please help? 'reads the text out of a delimited text file and puts the words and hints into to separate arrays ' this works and made the program run ' Dim filename As String = Application.StartupPath + "\ProggramingList.txt" 'this dosnt work and brings back a Illegal characters in path error. dim filename as string = My.Resources.GamesList Dim fields As String() 'my text files are delimited Dim delimiter As String = "," Using parser As New TextFieldParser(filename) parser.SetDelimiters(delimiter) While Not parser.EndOfData ' Read in the fields for the current line fields = parser.ReadFields() ' Add code here to use data in fields variable. 'put the result into two arrays (the fields are the arrays im talking about). one holds the words, and one holds the corresponding hint Programingwords(counter) = Strings.UCase(fields(0)) counter += 1 'this is where the hint is at Programingwords(counter) = (fields(1)) counter += 1 End While End Using
