• How can I pass a Visual Studio project's assembly version to another project for use in a post-build

  - by Coder7862396

  I have a solution with 2 projects: My Application 1.2.54 (C# WinForms) My Application Setup 1.0.0.0 (WiX Setup) I would like to add a post-build event to the WiX Setup project to run a batch file and pass it a command line parameter of My Application's assembly version number. The code may look something like this: CALL MyBatchFile.bat "$(fileVersion.ProductVersion($(var.My Application.TargetPath)))" But this results in the following error: Unhandled Exception:The expression """.My Application" cannot be evaluated. Method 'System.String.My Application' not found. C:\My Application\My Application Setup\My Application Setup.wixproj Error: The expression """.My Application" cannot be evaluated. Method 'System.String.My Application' not found. C:\My Application\My Application Setup\My Application Setup.wixproj I would like to be able to pass "1.2.54" to MyBatchFile.bat somehow.

• Viewing, building & debugging Borland C++ Builder project in Visual Studio 2010

  - by grunt

  I would like to use VC2010 to handle a BCB 2006 project I have. I do not want to convert the code to VC since much UI will need to be ported. I just want to be able to view build & debug from VS IDE. Viewing: I assume once I create VS projects for the native BCB code viewing will be possible, although the UI editor will not. Building: I found the "C++ Native Multi-Targeting" option of VS, although I'm not sure on what to set the different options there to (Daffodil is mentioned as helpful although I'm not sure what the added value is over existing functionality). Debugging: not sure how to do this at all from within VS. There are some stand alone console tools that convert debug info files e.g. tds2pdb (wheres the documentation link?). If anyone has experience with such a task I would thank you for any advice.

• Custom prerequsites to visual studio setup project

  - by Sandy

  I have a Visual Studio Setup project and have followed the steps mentioned in this link to load the Shared Add-in Support Update for the Microsoft .NET Framework 2.0 (KB908002) to the prerequisites list. The entry appears but there is this following warning shown No 'HomeSite' attribute has been provided for 'Shared Add-in Support Update for Microsoft .NET Framework 2.0 (KB908002)', so the package will be published to the same location as the bootstrapper. I use the Download component from the component vendor's website option. How do I set a homesite for this update so that the update is directly downloaded and installed. I do not want to distribute the update along with my setup. Thanks

• Use of LOC to determine project size

  - by acidzombie24

  How many lines of code (LOC) does it take to be considered a large project? How about for just one person writing it? I know this metric is questionable, but there is a significant difference, for a single developer, between 1k and 10k LOC. I typically use space for readability, especially for SQL statements, and I try to reduce the amount of LOC for maintenance purpose to follow as many best practice as i can. For example, I created a unified diff of the code I modified today, and it was over 1k LOC (including comments and blank lines). Is "modified LOC" a better metric? I have ~2k LOC, so it's surprising I modified 1k. I guess rewriting counts as both a deletion and addition which doubles the stats.

• Which C++ graph library should I use?

  - by mspoerr

  Hello, I found the following graph libraries, but I am not sure which one I should use. Maybe there are some more... Graphviz (http://www.graphviz.org/) Boost Graph Library (http://www.boost.org/doc/libs/1_42_0/libs/graph/doc/index.html) Lemon (http://lemon.cs.elte.hu/trac/lemon) igraph (http://igraph.sourceforge.net/introduction.html) What it should do: draw a undirected network map come as header only or static lib for Windows the output format should be user editable Graphviz is the only one I tried so far, but I found no static lib for it, I failed to build it by my own and the documentation could be better. Therefore I looked around and found these other three libs. I would be glad to get some recommendations which lib to choose. Thanks, /mspoerr

• Using MinGW to compile a SFML project

  - by Kyle Martin

  Okay, so I have a C++ project that uses SFML, and I want to be able to compile it from the CMD using MinGW. I have it so I can compile.cpp's, however, I just need to know what more I have to do in order for it to work with SFML. I tried compiling it with CodeBlocks and MinGW, and it works fine, until I try to run it, at which point it tells me that sfml-system.dll is missing from my computer. Does this mean I installed it incorrectly? I followed the CodeBlocks installation down to the letter, from what I could tell... I put the include\SFML in the include\ of MinGW, and I put all the *.a's from lib\ into the \lib of MinGW as well. Thank you for the help you can give! Kyle

• Genetic programming in c++, library suggestions?

  - by shuttle87

  I'm looking to add some genetic algorithms to an Operations research project I have been involved in. Currently we have a program that aids in optimizing some scheduling and we want to add in some heuristics in the form of genetic algorithms. Are there any good libraries for generic genetic programming/algorithms in c++? Or would you recommend I just code my own? I should add that while I am not new to c++ I am fairly new to doing this sort of mathematical optimization work in c++ as the group I worked with previously had tended to use a proprietary optimization package. We have a fitness function that is fairly computationally intensive to evaluate and we have a cluster to run this on so parallelized code is highly desirable. So is c++ a good language for this? If not please recommend some other ones as I am willing to learn another language if it makes life easier. thanks!

• How to break a series of git commits into patches for submission to another project

  - by krosenvold

  So I've been bashing away at my favorite open source project for quite some time, and It's time for submitting issues with patches back. I have to regroup my commits more or less fully, and hopefully extract some pieces of code that can function as distinct patches to avoid code bombing. Currently I usually do something like this: rebase/squash everything to one commit since the old ones often don't make sense as patches undo that commit start adding stuff that I think fits to one commit, using add/add -i commit stash the rest test that commit re-apply the stash and start from 3 until all is accounted for It works, but is there a better way ?

• search paths where one native library depends on another

  - by carneades

  I'm using JNA and Java but I think this question affects any native-to-nonnative bridge. I have a Java application which relies on lib1.dylib, and lib1.dylib relies on lib2.dylib. I want to put everything inside of my .app file on Mac. I can easily put lib1.dylib inside and set java.classpath (or NativeLibrary.addSearchPath()) to tell the JVM where to find lib1.dylib. The trouble is, I don't know how to communicate that lib1.dylib's dependencies are also in the location I provided. The result is that lib1 is loaded fine, but then lib2 can't be found since it's not in the operating system's library path. Anyone know how I can overcome this problem? I imagine it must come up plenty in big projects with large numbers of shared libraries.

• Problem deriving a user control from an abstract base class in website project

  - by Sprintstar

  In a Visual Studio website, I have created a user control. This control is derived from a class (in App_Code) that is itself derived from System.Web.UI.UserControl. This is an abstract class with an abstract method. I then try to implement that method in the user control, but I get the following errors from Visual Studio: Error 1 'WebUserControl.AbstractMethod()': no suitable method found to override C:\Users\User\Documents\Visual Studio 2010\WebSites\Delme\WebUserControl.ascx.cs 10 28 C:\...\Delme\ Error 2 'WebUserControl' does not implement inherited abstract member 'AbstractBaseClass.AbstractMethod()' c:\Users\User\AppData\Local\Temp\Temporary ASP.NET Files\delme\0eebaa86\f1a48678\App_Web_nrsbzxex.0.cs 14 Error 1 says that my override of the abstract method is invalid, it doesn't recognise the abstract method in the base class. Error 2 says that the partial class automatically built by asp.net doesn't implement the abstract method! Note that this works fine when the code is used in a Web Application project. Why is this happening?

• First Fluent NHibernate Project

  - by Andy

  I'm trying to follow the "Your first project" tutorial at http://wiki.fluentnhibernate.org/Getting_started and have hit a roadblock. When I try to run the console application, I'm getting this error: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail. I have created a SQLite database "firstProject.db" and referenced the full path to the file in the call to: return Fluently.Configure() .Database(SQLiteConfiguration.Standard .UsingFile(DbFile)) .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Program>()) .ExposeConfiguration(BuildSchema) .BuildSessionFactory(); so I don't know what I'm doing wrong. What/where is this "PotentialReasons" collection? Thank you for the help. Andy

• The ultimate .NET file and directory utility library?

  - by Serge van den Oever

  I find myself writing file and directory utility functions all the time, and I was wondering if there is good file and directory library that already implements a more extensive set than available by default in System.IO. The kind of functions I'm looking for is things like: public static void GetTemporaryDirectory() { string tempDirectory = Path.Combine(Path.GetTempPath(), Path.GetRandomFileName()); Directory.CreateDirectory(tempDirectory); return tempDirectory; } public static void CreateEmptyFile(string filename) { File.Create(filename).Dispose(); } public static void CreateEmptyFile(string path, string filename) { File.Create(Path.Combine(path, filename)).Dispose(); } public static void CreateDirectory(string path) { Directory.CreateDirectory(path); } public static void CreateDirectory(string path, string childpath) { Directory.CreateDirectory(Path.Combine(path, childpath)); }

• Paypal Payflow pro library

  - by John Stewart

  I already have an express checkout integrated with my Codeigniter application. Now I want to integrate seamless paypal where I collect the CC information and pass it to Paypal (via backend) and once everything is approved, my application shows that to the user. All this with out ever going to Paypal's website. I know that Paypal gives a bunch of sample code but they have so many different products that advertise to do the same thing. Is there any wrapper library in PHP that I can use for handling all this? What sort of design decision is involved in migrating to such system? Would I need SSL certificates for this?

• Publish failed in Web Application Project (MVC)

  - by Stuck

  I usually use the "Publish" feature in VS 2008 to get the correct files and so on that I can publish to my website. But from time to time publish fails without any good error message at all. I know that it can be a couple of different reasons but I am starting to grow really tired with this now. Can anyone teach me how to build the website from the command line? As I said it is a MVC project. Can I use the aspnet_compiler for this? What parameters should I use to simulate the same behavior as a "Publish"?

• Implementing Qt File Dialog with a Different File System Library (boost)

  - by knight

  Hi, I am writing an application which requires me to use another file system and file engine handlers and not the qt's default ones. Basically what I want to be able to do is to use qt's file dialog but have an underlying file system handler (for example built using boost file system library) of mine handling all the operations with regards to file and directory operations within that dialog. I have already written a custom file engine which handles some of the operations but I am now stuck with Qt's file system model and the file system watcher engine, as I need to have the signals transmitted for this custom file engine. Seems like I have a daunting task ahead. Am I heading in the right direction? Is there any other simpler way that I could implement this? Can anyone give me any idea on how to proceed. I was thinking of looking into proxy models but not sure if that would work. Thanks in advance for any help.

• The procedure entry point_except_handler4_common could not be located in the dynamic link library msvcrt.dll

  - by Psilokan

  As I had feared some of our old VB6 projects are not playing nice with Windows 7. Some of our customers have already upgraded and our one product is returning this error every time you run the executable: The procedure entry point_except_handler4_common could not be located in the dynamic link library msvcrt.dll First thing I tried was creating a .local in the folder so it uses all the DLL and OCX files packaged with the product. That didn't do anything, though I'm not sure if this .local trick still works in Win7. Tried turning on compatibility for several previous versions of Windows, that had no effect either. Hopefully someone else has some more suggestions, as my Google-Fu has failed me on this one.

• Maven project is in a subfolder, can't get Eclipse integration to work

  - by tputkonen

  Inside the folder 'ProjectName' exists several subfolders, and of them contains java program: ProjectName Specifications JavaCode Gfx ... JavaCode folder contains pom.xml. I have installed m2eclipse (0.10.x) to Eclipse and imported whole ProjectName folder to Eclipse. Subfolders are displayed correctly but maven integration is not working correctly - for example I don't see src/main/java "shortcut" folder in Eclipse, but I have to click to open all folders. If I create a new maven project with Eclipse from scratch, the integration works well. What could be the issue?

• Vim: multi-file editing - having different makes in different splits

  - by gmatt

  I'm a recent vim convert (from fancy IDEs like eclipse.) I love the :make command in vim and use it extensively; however I also like to edit multiple projects (with separate makefiles.) So usually to edit more than one project I will do pushd project1 vim project1.cpp [suspend signal] pushd ../project2 vim project2.cpp and now I can switch between the two projects with ctrl+z i.e. suspend signal, and fg. When this becomes an issue is when I want to open one project in the context of another so I can do copy/pasting. So if instead in the above I do pushd project1 vim project1.cpp :vsp ../project2/project2.cpp I can edit both concurrently in the same vim process, however I can't effectively build one or the other with the :make command, it will only build project 1. Does anyone have some kind of scheme that gives them the best of both worlds: being able to edit concurrently while still being able to build multiple projects with the :make command all from the same vim process?

• SharePoint Documents Library - Change "Document Created By" field

  - by yellowblood

  Hello, I have a code that changes the username in various SharePoint lists, mostly by the "Author" column. It all works fine on normal lists, but it doesn't seem to work on the "Shared Documents" list which is a document library. Whether I change the username in "Created By" or "Document Created By", the change doesn't seem to take effect. The item.Update command doesn't throw any exception, but it clearly doesn't update the field(s). What can I do if I want to change this field through code? Thanks

• Java library to partially export a database while respecting referential integrity constraints

  - by Mwanji Ezana

  My production database is several GB's uncompressed and it's getting to be a pain to download and run locally when trying to reproduce a bug or test a feature with real data. I would like to be able to select the specific records that interest me, then have the library figure out what other records are necessary to produce a dataset that respects the databases integrity constraints and finally print it out as a list of insert statements or dump that I can restore. For example: given Author, Blog and Comment tables when I select comments posted after a certain date I should get inserts for the Blog records the comments have foreign keys to and the Author records those Blogs have foreign keys to.

• Opening vbp Visual Basic Project

  I have got some old sources written in Visual Basic. There are *.bas, *.cls, *.frm and *.vbp files. As I understand, vbp is a project file. But I cannot open it with my Visual Studio 2008. What version of VS should I install to open *.vbp file? Google says it is Visual Studio 6, but I am not sure and I cannot find Visual Studio 6 for downloading. Is there any publicly available free edition of Visual Studio 6 with Visual Basic? Thanks.

• How to change font size using the Python ImageDraw Library

  - by Eldila

  I am trying to change the font size using python's ImageDraw library. You can do something like this: fontPath = "/usr/share/fonts/dejavu-lgc/DejaVuLGCSansCondensed-Bold.ttf" sans16 = ImageFont.truetype ( fontPath, 16 ) im = Image.new ( "RGB", (200,50), "#ddd" ) draw = ImageDraw.Draw ( im ) draw.text ( (10,10), "Run awayyyy!", font=sans16, fill="red" ) The problem is that I don't want to specify a font. I want to use the default font and just change the size of the font. This seems to me that it should be simple, but I can't find documentation on how to do this.

• What version number should an unreleased project receive?

  - by Byran

  Note: I'm new to version numbering. Please excuse my ignorance. I have a project where an attempted major release (Version B) was abandoned then later re-attempted and release (Version C). Each version has major changes from the previous version that I wouldn't consider an minor update. Little to nothing of Version B made it into Version C. Version A (1.0) Developed, released, updated, etc. Version B (???) Developed, suspended, abandoned. Version C (2.0) Developed, released, updated, etc. I feel like I should have version them like so, but worried about confusion of the missing version: Version A (1.0) Version B (2.0) Version C (3.0)
