  • How do I get my Windows Forms application to use a custom main function and get access to the Applic

    - by burble
    Hi Folks I am trying to use a Main () function in a class to control the program flow in my vb .net Windows Forms application. I have added a splash screen component and a login screen, and customised my main sdi form. I have set the startup form to be my main function in the Application Page of the Project Designer, and everything seems to work fine(ish). However, I would like to use: Me.MinimumSplashScreenDisplayTime = 5000 to ensure that the splash screen is visible, but it is not recognised by the system unless I tick the Enable Application Framework check box on the Project Designer. If I do this, on startup the program ignores the login and splash screens and all my customisation and just displays a default Form1, even though I have also specified my splash screen in the AF dropdown list. Of course, there are alternative ways to delay a splash screen, such as putting the thread temporarily to sleep (which didn't seem to work), but I suspect that there are other things in the AF that I may want to use. Any suggestions on how I can get round this please, and get a sensible means of controlling program flow? Any thoughts on the best overall structure for organising program flow would also be helpful too. I am concerned both about going down a Microsoft or an alternative custom route that may cause me problems later, as the application becomes more complex. Thankses.

  • What does a DependencyReplicator.xml file look like?

    - by Fadeproof
    I am trying to get started using Dependency Replicator http://www.codeplex.com/tfsdepreplicator. There is no documentation in place and therefore no example of a DependencyReplicator.xml file which I need in order to take my experiment further. Can anyone using Dependency Replicator supply a demo .xml file?

    @interface MainViewController : UIViewController < FlipsideViewControllerDelegate { } I am quite new to object oriented languages & especially obj.c. I need to use addressbook framework within this class.Apple documentation suggests this code: @interface ViewController : UIViewController < ABPeoplePickerNavigationControllerDelegate {} I was wondering how to use at the same time FlipSideControllerDelegate & ABPeoplePickerControllerDelegate. In fact I really can't understand what i am doing:)

  • Parallelizing L2S Entity Retrieval

    - by MarkB
    Assuming a typical domain entity approach with SQL Server and a dbml/L2S DAL with a logic layer on top of that: In situations where lazy loading is not an option, I have settled on a convention where getting a list of entities does not also get each item's child entities (no loading), but getting a single entity does (eager loading). Since getting a single entity also gets children, it causes a cascading effect in which each child then gets its children too. This sounds bad, but as long as the model is not too deep, I usually don't see performance problems that outweigh the benefits of the ease of use. So if I want to get a list in which each of the items is fully hydrated with children, I combine the GetList and GetItem methods. So I'll get a list and then loop through it getting each item with the full cascade. Even this is generally acceptable in many of the projects I've worked on - but I have recently encountered situations with larger models and/or more data in which it needs to be more efficient. I've found that partitioning the loop and executing it on multiple threads yields excellent results. In my first experiment with a list of 50 items from one particular project, I did 5 threads of 10 items each and got a 3X improvement in time. Of course, the mileage will vary depending on the project but all else being equal this is clearly a big opportunity. However, before I go further, I was wondering what others have done that have already been through this. What are some good approaches to parallelizing this type of thing?

  • In the meantime, to be or not to be ... productive!

    - by Jan Kuboschek
    I just moved back to Europe from the US after living there for 7 years. Apart from major adjustment issues, I'm currently looking for a job over here. I'm mainly interested in (IT) Consulting and, since these jobs typically require programming knowledge, such as Java, I'm trying to think of something productive to write (perhaps to demo my skills) while I'm waiting for my interviews (starting in two weeks. Folks here are a bit slower than in the US apparently...). I graduated from college about a year and a half ago and have a 4 year degree in international management/economics and about 3/4 of a 2 year degree in computer science finished. I've written my fair share of web software over the years, but nothing concrete that I could show, especially not in Java. Now, I've never had the problem of not having any idea what to write. Basic games I could write, but I'm not sure how well that'll come over when I walk into my interview and say "hey, I was bored. Take a look at my multiplayer space invaders game! Wanna try beating me??". Any thoughts? I browsed SourceForge the other day to find a nice little project to contribute to, but decided that I don't want to commit to someone else's project at this time. Any ideas, perhaps from someone who has been, or currently is, in a similar position would be much appreciated. Oh, and lastly: Instead of developing a program or two to demonstrate my skills, I could spend my time brushing up on UML and Perl. Any suggestions regarding that? Writing a demo vs. learning something new?

  • Javascript int variable from ASP.NET MVC Model data?

    - by Anders Svensson
    I need to get model data into a javascript variable and use it as an int to compare values. But I can only figure out how to get the model data as strings, otherwise the compiler complains. So how can I get the max and taskBudgetHours as int variables in the Javascript? <script type="text/javascript"> $(document).ready(function () { $("#taskForm").submit(function (e) { var taskBudgetHours = $('#BudgetHours').val(); var max = '<%: Model.Project.RemainingBudgetHours %>'; var test = 'test'; alert(taskBudgetHours); alert(max); if (taskBudgetHours <= max) { //This doesn't work, seems to treat it as strings... return true; } else { //Prevent the submit event and remain on the screen e.preventDefault(); alert('There are only ' + max + ' hours left of the project hours.'); return false; } }); return; }); </script>

  • Maven build issue with Hibernate for Windows

    - by wishi_
    Hi! I'm getting build errors for for my Maven enabled project related to the Hibernate extension. - It's a very basic app, and I was able to solve this issue on my Linux box by manually installing some required artifacts: mvn install:install-file -DgroupId=javassist -DartifactId=javassist -Dversion=3.9.0 -Dpackaging=jar -Dfile=foo.jar That worked out (Hibernate as a set of required deps). But in case of Windows things are different. How do I add the dependencies manually to Maven on Windows? 1) org.hibernate:hibernate:jar:3.3.2 Try downloading the file manually from the project website. Then, install it using the command: mvn install:install-file -DgroupId=org.hibernate -DartifactId=hibernate -Dversion=3.3.2 -Dpackaging=jar -Dfile=/path/to/file 2) javassist:javassist:jar:3.9.0 Can I automate this cumbersome manual dependency installation for my coworkers on their Windows machines? Are there any helpful tools or GUI that can perform these tasks? The best way would be that Maven does it all automatically. I'm not too familiar with it jet. Thanks for answers.

  • Using low level api for datastore in google app engine ? is it bad ?

    - by Chez
    There is little documentation on how to use the low level api for datastore and quite a lot on JPA and JDO and how it translates to it. My question is: is there any advantage in coding against the JPA or JDO specs instead of accessing directly the low level api for datastore ? From an initial look, it seems simple and straight forward but I am not sure if there are good reasons why not to do it. Thanks Cx

  • Drop down view in cocoa

    - by coffeebean
    I'm looking to create a 'drop down' view that falls in front of the main window. An example of this would be the window that drops down when you click 'Advanced' in System Preferences-Networking. If someone could point me in the right direction documentation-wise that would be great. Thanks in advance.

  • Is there a Designer for MFC in Visual Studio like for windows forms in .NET?

    - by claws
    I'm a .NET programmer. I've never developed anything in MFC. Currently I had to write a C++ application (console) for some image processing task. I finished writing it. But the point is I need to design GUI also for this. Well, there won't be anything complex. Just a window with few Buttons, RadioButtons, Check Boxes, PicturesBox & few sliders. thats it. I'm using VS 2008 and was expecting a .NET style form designer. Just to test, I created a MFC project (with all default configuration) and these files were created by default: ChildFrm.cpp MainFrm.cpp mfc.cpp mfcDoc.cpp mfcView.cpp stdafx.cpp Now, I'm unable to find a Designer. There is no View Designer. I've opened all the above *.cpp and in the code editor right clicked to see "Designer View". ToolBox is just empty because I'm in code editor mode. When I built the project. This is the window I get. How to open a designer?

  • When would isSearchable return false for an Oracle JDBC column?

    - by Ian Varley
    In what cases would a call to java.sql.ResultSetMetaData.isSearchable(int col) return false for an Oracle database? The documentation for the method doesn't really answer the question: "Indicates whether the designated column can be used in a where clause." I can think of only one case - when the column is the result of an aggregate function (in which case it would have to be part of a HAVING filter, not a WHERE filter). Are there any other cases?

  • In need of a good MATLAB class tutorial

    - by rlbond
    I'm having a lot of trouble trying to figure out how to use classes in MATLAB. I'm very familiar with C++ and Python but I just can't figure anything out about how to define classes in MATLAB. Does anyone know a very good resource with lots of examples? The official documentation leaves much to be desired.

  • Running an application from an USB device...

    - by Workshop Alex
    I'm working on a proof-of-concept application, containing a WCF service with console host and client, both on a single USB device. On the same device I will also have the client application which will connect to this service. The service uses the entity framework to connect to the database, which in this POC will just return a list of names. If it works, it will be used for a larger project. Creating the client and service was easy and this works well from USB. But getting the service to connect to the database isn't. I've found this site, suggesting that I should modify machine.config but that stops the XCopy deployment. This project cannot change any setting of the PC, so this suggestion is bad. I cannot create a deployment setup either. The whole thing just needs to run from USB disk. So, how do I get it to run? (The service just selects a list of names from the database, which it returns to the client. If this POC works, it will do far more complex things!)

  • better understanding of getline() and cin

    - by numerical25
    Trying to get some basic understanding of console functionalities. I am having issues so consider the following... #include "stdafx.h" #include<iostream> #include<conio.h> using namespace std; /* This is a template Project */ void MultiplicationTable(int x); int main() { int value = 0; printf("Please enter any number \n\n"); getline(cin, value); MultiplicationTable(value); getchar(); return 0; } I actually based this off code from http://www.cplusplus.com/doc/tutorial/basic_io/ . My IDE is not recognizing getline() so of course when I compile the application. I get an error 'getline': identifier not found Now take a look at this code #include "stdafx.h" #include<iostream> #include<conio.h> using namespace std; /* This is a template Project */ void MultiplicationTable(int x); int main() { int value = 0; printf("Please enter any number \n\n"); cin>>value; MultiplicationTable(value); getchar(); return 0; } When I execute this line of code the console window opens and immediately closes. I think I a missing something about cin. I do know that it delimits spaces but I don't know what else. what should I use for input to make my life easier.

  • Allocation of memory with LE routines

    - by HaWe
    At /questions/2000777/allocation-of-memory-in-variable-length-tables NealB mentioned LE routines to allocate/deallocate memory in a non-CICS COBOL program. I'd very much like to know how this is done: how the LE routine is called. (I'm familiar with the LINKAGE SECTION and with SET ADDRESS.) Since I have no access to an IBM mainframe at the moment - meaning no access to online documentation - some code snippets could enlighten me.

  • C++: Constructor/destructor unresolved when not inline?

    - by Anamon
    In a plugin-based C++ project, I have a TmpClass that is used to exchange data between the main application and the plugins. Therefore the respective TmpClass.h is included in the abstract plugin interface class that is included by the main application project, and implemented by each plugin. As the plugins work on STL vectors of TmpClass instances, there needs to be a default constructor and destructor for the TmpClass. I had declared these in TmpClass.h: class TmpClass { TmpClass(); ~TmpClass(); } and implemented them in TmpClass.cpp. TmpClass::~TmpClass() {} TmpClass::TmpClass() {} However, when compiling plugins this leads to the linker complaining about two unresolved externals - the default constructor and destructor of TmpClass as required by the std::vector<TmpClass> template instantiation - even though all other functions I declare in TmpClass.h and implement in TmpClass.cpp work. As soon as I remove the (empty) default constructor and destructor from the .cpp file and inline them into the class declaration in the .h file, the plugins compile and work. Why is it that the default constructor and destructor have to be inline for this code to compile? Why does it even maatter? (I'm using MSVC++8).

  • What is the proper method to stop loading a Flex Module before it has completely loaded?

    - by Michael Prescott
    I seem to recall that Loader.unload() could once be used to stop loading a swf before it had finished loading. I can no longer find documentation or the blog where I read this. Perhaps it was an unofficial feature. Anyhow, IModuleInfo, returned by ModuleManager.getModule() has an unload() method. If I want to halt loading a Flex Module that is in progress, do I just call iModuleInfo_instance.unload()?

  • C# why unit test has this strange behaviour?

    - by 5YrsLaterDBA
    I have a class to encrypt the connectionString. public class SKM { private string connStrName = "AndeDBEntities"; internal void encryptConnStr() { if(isConnStrEncrypted()) return; ... } private bool isConnStrEncrypted() { bool status = false; // Open app.config of executable. System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); // Get the connection string from the app.config file. string connStr = config.ConnectionStrings.ConnectionStrings[connStrName].ConnectionString; status = !(connStr.Contains("provider")); Log.logItem(LogType.DebugDevelopment, "isConnStrEncrypted", "SKM::isConnStrEncrypted()", "isConnStrEncrypted=" + status); return status; } } Above code works fine in my application. But not in my unit test project. In my unit test project, I test the encryptConnStr() method. it will call isConnStrEncrypted() method. Then exception (null pointer) will be thrown at this line: string connStr = config.ConnectionStrings.ConnectionStrings[connStrName].ConnectionString; I have to use index like this to pass the unit test: string connStr = config.ConnectionStrings.ConnectionStrings[0].ConnectionString; I remember it worked several days ago at the time I added above unit test. But now it give me an error. The unit test is not integrated with our daily auto build yet. We only have ONE connectionStr. It works with product but not in unit test. Don't know why. Anybody can explain to me?

  • Output error in comparing characters from two strings

    - by Andrew Martin
    I'm stuck with my a piece of code I'm creating. My IDE is Eclipse and when I use its debugging feature, to trace what's happening on each line, it outputs perfectly. However, when I click the "run" project, it just outputs a blank screen: public static void compareInterests(Client[] clientDetails) { int interests = 0; for (int p = 0; p < numberOfClients; p++) { for (int q = 0; q < numberOfClients; q++) { String a = clientDetails[p].getClientInterests(); String b = clientDetails[q].getClientInterests(); int count = 0; while (count < a.length()) { if (a.charAt(count) == b.charAt(count)) interests++; count++; } if ((interests >= 3) && (clientDetails[p].getClientName() != clientDetails[q].getClientName())) System.out.print (clientDetails[p].getClientName() + " is compatible with " + clientDetails[q].getClientName()); interests = 0; } } } The code is designed to import an object array which contains information on a client's name and a client's interests. The client's interests are stored in the format "01010", where each 1 means they are interested in that activity, each 0 means they are not. My code compares each character of every client's string with every other client's string and outputs the results for all client's that don't have the same name and have three or more interests in common. When I run this code through Java's debugger, it outputs fine - but when I click run project or compile, I just get a blank screen. Any ideas?
