  • Dynamic Connection Strings for Strongly Typed DataSet in a Class Library using App.Config

    - by Luc
    This is my first question on StackOverflow.com and I'm not sure if this is the correct way to do this. I found a similar question titled: Modifying the Data Source for the Strongly Typed Dataset Connection String. However, the answer provided is not working for me. I'm not able to comment on it because I don't have enough "reputation points" (again, I just signed up), and I didn't want to provide an "answer", because I don't know the correct answer. My problem is that I need to be able to modify the connection string inside the generated myproject.dll.config file, but doing so has no effect for me at all. My library still uses the default connection string that was setup at design time. I've tried everything I know to try, but still no luck. I've tried working around the issue using multiple different approaches, but still the problem persists. I can't find any help on the internet with my specific problem either. It would be great if somebody could shed some light as to why my modified config file isn't being read. Useful information: I'm using a Strongly Typed DataSet I don't know the actual connection string at design time. The app.config doesn't allow me to specify a 'User' scoped connection string. I'm tied to a class library (no Windows Forms) Thank you for any help! Luc

  • How do I add a static library target that compiles before an application compiles in Xcode?

    - by Koning Baard XIV
    I'm creating a static library in C++. The static library itself links to nothing. To test the static library, I'm creating a test program in C++ (you know, with a main function). Now, I want that whenever I click Build in Xcode, it compiles the static library first, then compiles the test program and link that test program to the static library, like this: # The steps indicate the order Xcode should compile it # (Step 1) Static Library <----------. | (Step 2) Test Program -------> Standard Library Also, the test program should use the header files of the static library. Can anyone explain me how to configure this in Xcode? Thanks

  • Image drawing library for Haskell?

    - by absz
    I'm working on a Haskell program for playing spatial games: I have a graph of a bunch of "individuals" playing the Prisoner's Dilemma, but only with their immediate neighbors, and copying the strategies of the people who do best. I've reached a point where I need to draw an image of the world, and this is where I've hit problems. Two of the possible geometries are easy: if people have four or eight neighbors each, then I represent each one as a filled square (with color corresponding to strategy) and tile the plane with these. However, I also have a situation where people have six neighbors (hexagons) or three neighbors (triangles). My question, then, is: what's a good Haskell library for creating images and drawing shapes on them? I'd prefer that it create PNGs, but I'm not incredibly picky. I was originally using Graphics.GD, but it only exports bindings to functions for drawing points, lines, arcs, ellipses, and non-rotated rectangles, which is not sufficient for my purposes (unless I want to draw hexagons pixel by pixel*). I looked into using foreign import, but it's proving a bit of a hassle (partly because the polygon-drawing function requires an array of gdPoint structs), and given that my requirements may grow, it would be nice to use an in-Haskell solution and not have to muck about with the FFI (though if push comes to shove, I'm willing to do that). Any suggestions? * That is also an option, actually; any tips on how to do that would also be appreciated, though I think a library would be easier.

  • Codeigniter: Library function--I'm stuck

    - by Kevin Brown
    I have a library function that sets up my forms, and submits data. They're long, and they work, so I'll spare you reading my code. :) I simply need a way for my functions to determine how to handle the data. Until now, the function did one thing: Submit a report for the current user. NOW, the client has requested that an administrator also be able to complete a form--this means that the form would be filled out, and it would CREATE a user at the same time, whereas the current function EDITS and is accessed by an EXISTING user. Do I need a separate function to do essentially the same thing? How do I make one function perform two tasks? One to update a user, and if there is no user, create one. Current controller: function survey() { $id = $this->session->userdata('id'); $data['member'] = $this->home_model->getUser($id); //Convert the db Object to a row array $data['manager'] = $data['member']->row(); $manager_id = $data['manager']->manager_id; $data['manager'] = $this->home_model->getUser($manager_id); $data['manager'] = $data['manager']->row(); $data['header'] = "Home"; $this->survey_form_processing->survey_form($this->_container,$data, $method); } Current Library: function survey_form($container) { //Lots of validation stuff $this->CI->validation->set_rules($rules); if ( $this->CI->validation->run() === FALSE ) { // Output any errors $this->CI->validation->output_errors(); } else { // Submit form $this->_submit(); } $this->CI->load->view($container,$data); The submit function is huge too. Basically says, "Update table with data where user_id=current user" I hope this wasn't too confusing. I'll create two functions if need be, but I'd like to keep redundancy down! }

  • Unmanaged DLL (exporting Dialog) + Class Library (DLL) + no Windows Style/Themes

    - by Gohlool
    Hi, I have a managed application TestApplication.exe in C# and Application.EnableVisualStyles() is allready called. I have a Class Library MySharedCode.dll also in C# which uses [DLLImport()] to import some External dialogs out of an unmanaged dll. Well, now I am using (add reference) MySharedCode.dll in my TestApplication.exe and call a function MyTestConfigDlg() out of it. TestClass.MyTestConfigDlg(); OK, everything works fine and I get my dialog, but the dialog has NO XP style/themes? I just wanted to see if it's general problem with managed/unmanged modules, so I used the [DLLImport()] to call the same MyTestConfigDlg() dialog but this time directly in my TestApplication.exe! WOW! Worked as I expected. The Dialog was in XP Style/Themes! so, anybody here who can help me out? FYI: I also tried (just for test) to call MessageBoxA() API call in my Class Library Dll which later called by my TestApplication.exe and the MessageBoxA() had also no Style/Themes! Thanks in advance!

  • C headers: compiler specific vs library specific?

    - by leonbloy
    Is there some clear-cut distinction between standard C *.h header files that are provided by the C compiler, as oppossed to those which are provided by a standard C library? Is there some list, or some standard locations? Motivation: int this answer I got a while ago, regarding a missing unistd.h in the latest TinyC compiler, the author argued that unistd.h (contrarily to sys/unistd.h) should not be provided by the compiler but by your C library. I could not make much sense of that response (for one thing shouldn't that also apply to, say, stdio.h?) but I'm still wondering about it. Is that correct? Where is some authoritative reference for this? Looking in other compilers, I see that other "self contained" POSIX C compilers that are hosted in Windows (like the GCC toolchain that comes with MinGW, in several incarnations; or Digital Mars compiler), include all header files. And in a standard Linux distribution (say, Centos 5.10) I see that the gcc package provides a few header files (eg, stdbool.h, syslimits.h) in /usr/lib/gcc/i386-redhat-linux/4.1.1/include/, and the glibc-headers package provides the majority of the headers in /usr/include/ (including stdio.h, /usr/include/unistd.h and /usr/include/sys/unistd.h). So, in neither case I see support for the above claim.

  • Cross-platform general purpose C++ RPC library

    - by iUm
    Here's the task: Imagine, we have an applications and a plug-in for it (dynamic library). Interface between the application and the plug-in is completely defined. Now I need to run the application and the plug-in on different computers. I wrote a stub for the plug-in on a computer where the real applications is running. And the application loads it and calls its functions like if it were a native plug-in. On the other computer there's a stub instead of the real application, which loads the native plug-in. Now I need to organize RPCs between my stubs over the network, regardless the very transport. Usually, it's not difficult. But there're some restrictions: Application-plug-in interaction can be reenterable (e.g. application calls f1() from plug-in, in f1() plug-in calls g1() from application, in g1() application calls f2() from plug-in and so on...) Any such reenteration should be executed exactly by the same thread, which started the sequence Where can I find a cross-platform C++ RPC library with such features?

    - by Vadim
    I'm having trouble to execute scalar function using Enterprise Library 5.0. The code looks something like that: somedDb.ExecuteScalar(CommandType.Text, "SELECT dbo.MyFunction('param')"); When the code is executed, I get the following error: Cannot find either column "dbo" or the user-defined function or aggregate "dbo.MyFunction", or the name is ambiguous.

    Hey Everyone, I'm looking for a free C++ library that can load .xls files in both Windows and Linux. If I had to make a choice, Linux would be the bare minimum.

  • Creating a java library

    - by Albinoswordfish
    This may be a silly question, but right now I have a rather large class that I want to use as a library. Where somebody can simply add this jar file to their classpath. And then simply do an import statement at the top, then he or she can start using this class. Is there anything special I need to do or can I simply just use the jar file built?

  • Good Java graph algorithm library?

    - by Nick Fortescue
    Has anyone had good experiences with any Java libraries for Graph algorithms. I've tried JGraph and found it ok, and there are a lot of different ones in google. Are there any that people are actually using successfully in production code or would recommend? To clarify, I'm not looking for a library that produces graphs/charts, I'm looking for one that helps with Graph algorithms, eg minimum spanning tree, Kruskal's algorithm Nodes, Edges, etc. Ideally one with some good algorithms/data structures in a nice Java OO API.
