  • Missing DLL Problem

    - by Liran
    Hi everyone. I have a C++ native application that was built under VS2005 (sp1),On machine A. (Debug Mode) Now,I need to run this application on a "clean" computer, Clean means it has no VS installed on. When i copy the runtime folder from machine A to the "clean" machine and try to activate the application it demands to reinstall the application. obviously missing DLLs are causing this problem cause on machine A the app works just fine, Is there any "clean" solution for this kind of problem besides gessing which DLLs are missing ? maybe a smart tool or installer that indicates which DLLs are missing at the runtime ? Thanks, Liran

  • Adventures on Enterprise Library 5.0: Who moved my cheese (namespace)

    - by Junior Mayhé
    Jesus, Krishna, Budda! I've migrated to EntLib 5.0, but classes like ISymmetricCryptoProvider are not recognized anymore. Funny to say that Data, Logging and other blocks are working compiling fine. Here's the problematic class: using System; using System.Collections.Generic; using System.Text; using Microsoft.Practices.EnterpriseLibrary.Common.Configuration;//-->it's not working anymore using Microsoft.Practices.EnterpriseLibrary.Security.Cryptography;//-->it's not working anymore namespace MyClassLibrary.Security.EnterpriseLibrary { public sealed class Crypto { public static ISymmetricCryptoProvider MyProvider { get { //IConfigurationSource is not recognized either, neither SystemConfigurationSource IConfigurationSource cs = new SystemConfigurationSource(); SymmetricCryptoProviderFactory scpf = new SymmetricCryptoProviderFactory(cs); ISymmetricCryptoProvider p = scpf.CreateDefault(); return p; } } The references are fine on project too. I really don't know why this particular project it's causing too many trouble on VS2010! Older references were deleted, project was cleaned, rebuilt, but can't make it compile :-( The references are: Microsoft.Practices.EnterpriseLibrary.Common Microsoft.Practices.EnterpriseLibrary.Logging Microsoft.Practices.EnterpriseLibrary.Logging.Database Microsoft.Practices.EnterpriseLibrary.Security Microsoft.Practices.EnterpriseLibrary.Security.Cryptography Why some namespaces can be found while others can't?

  • design pattern tools to use?

    - by ajsie
    i have noticed that every area has some tools you can use to make things easier. eg. css = dreamweaver doctrine/propel = orm designer // you dont have to hardcore code schemas manually and remembering all the syntax/variables mysql = mysql workbench // the same etc. in this way you get aided and dont have to type things the hard way, and can learn the structure, but then use GUI tools to help you develop faster. now i'm learning design patterns (singleton, factory, command, memento etc) and im wondering if there are some kind of tools you can use that will help you develop faster. i dont know exactly what tools i'm trying to find, just helping me when coding with design patterns (schema drawings? references?) are there any?

  • Create a dynamic control and AddHandle WITH Values/Brackets

    - by Jacob Kofoed
    Hi, it seems that adding for example a button Dim myButton as New Button and then addHandler to mySub("lol", 255) is not possible. Where mySub is Shared Sub MySub(byRef myString as string, myInteger as Integer) So: addHandler myButton.click, addressOf mySub("lol", 255) - returns an error saying it does not work with parentheses or whatever. I somehow see why this might not be possible, so I'm looking for a work-around on this problem. Please help _jakeCake

  • C++ String manipulation isn't making sense to me...

    - by Andrew Bolster
    I am trying some of the Stanford SEE courses online to learn some new languages; this particular assignment has to do with removing substrings from strings. What I've got so far is below, but if text = "hello hello" and remove ="el", it gets stuck in a loop, but if i change text to text = "hello hllo", it works, making me think I'm doing something obviously stupid. There is a stipulation in the assignment not to modify the incoming strings, and instead to return a new string. string CensorString1(string text, string remove){ string returned; size_t found=0, lastfound=0; found = (text.substr(lastfound,text.size())).find(remove); while (string::npos != found ){ returned += text.substr(lastfound,found); lastfound = found + remove.size(); found = (text.substr(lastfound,text.size())).find(remove); } returned += text.substr(lastfound,found); return returned; } Guidance would be appreciated :-) Thanks

  • Junctions or Virtual Directories for Web Applications?

    - by Kevin
    I see that junctions are a common way of referencing shared code in many projects. However, I have not seen them used in web applications before. Our team is exploring the possibility of abandoning virtual directories in favor of junctions to simplify our build process. My goal is to compile a list of pros and cons in order to make an informed decision regarding this change. Is it more appropriate to use junctions or virtual directories on web application projects? Environment is ASP.NET, IIS6/IIS7, VS.NET.

  • Is there server-side code which is not cross browser compatible?

    - by Ygam
    Was there a case in any server-side language where a code did not work in a browser while it did work in the rest? I am asking this because I can't imagine such a scenario because server-side code runs in the server, not in the browser but I have seen discussions where, as said, there were "server-side browser compatibility issues". I can't seem to recall where I have read it. Thanks in advance :)

  • Is it possible to have more than P2P on iPhone with Bluetooth

    - by Ricardo Ferreira
    Hi all, This seems like a straightforward google search answer, but after a while, I still can't be 100% sure of this. I've found Z2Live (http://www.z2live.com/), which is basically a layer above GameKit and they too use only P2P with Bluetooth. So I just want to be sure if I can only have P2P with Bluetooth or if I can have like 4 iPhones all connected to a server (who will also be a client) using Bluetooth. Thanks in advance.

  • Generate combinations by order and fixed length.

    - by roconmachine
    Suppose there is array main[] = [a,b,c,....z]; a[] = [a1,a2,a3,....] , b[] = [b1,b2,b3,....] and so on. So if we generate combination in main.length of ordered then it looks like ..... a1 b1 c1, a1 b1 c2, a1 b1 c3 ...... a1 b2 c1, a1 b3 c1, ..... a2 b1 c1, a3 b1 c1, ..... and total count will be a.length * b.length * c.length ........ = ? So write a code in any language to generate those combination. all the best. alex

  • how to run href="#var=something" before onclick function fires in javascript?

    - by korben
    i'm using the below javascript to change an image on an aspx in asp.net c# <script language="JavaScript" type="text/javascript"> var updateImageWhenHashChanges = function() { theImage = document.getElementById("ctl00_ContentPlaceHolder1_Image1a"); if(window.location.hash == "#size=2") { theImage.src = "<%# Eval("realfilename", "/files/l{0}") %>"; } else if(window.location.hash == "#size=3") { theImage.src = "<%# Eval("realfilename", "/files/{0}") %>"; } else if(window.location.hash == "#size=1") { theImage.src = "<%# Eval("fullthumbname", "/thumbnails/{0}") %>"; } else { } } </script> here's how i call it with a link <a href="#size=3" onclick="updateImageWhenHashChanges();">test</a> the problem is that it only does what i'm expecting on the SECOND click of the link, because it seems onclick fires before the href, so the first time i'm just placing the var and the 2nd time i'm actually getting what i want. does anyone know how i can fix this? i'm trying to get the image to change on each click

  • User Interface Diagram That is always reachable

    - by Fosa
    If you have to build a flow of a Use-case by drawing each Interface Diagram. Then you would start with a Diagram like say "login". But after the login page, no mather wich page you choose except the "logout" page, you always have your navigation bar right ? So all the options in the navigation bar? Like account page , personal page, etc... Do you have to make sure in your flow that in every diagram there is acces to the "accountpage" diagram ? Or do they have an other solution for that ? Thanx in advance

  • vs2008, opencv2.1,compile error in cxcore.hpp

    - by Long Gu
    Hi, gurus: I installed opencv2.1, made a new project (proj_A) using vs2008, used it for my computer vision tasks, it works fine. I copied an old project (proj_B, also made using vs2008) from other PC, compile it with ".h" and ".lib" files copied from opencv1.0 (which I did not install onto my PC), it compiles fine. I re-directed ".h" and ".lib" files in proj_B to opencv2.1 folders instead, compiled the proj_B, and then I got these errors from cxcore.hpp: class CV_EXPORTS RNG { public: enum { A=4164903690U, UNIFORM=0, NORMAL=1 }; // errors here, line 936 errors are: 5c:\opencv2.1\include\opencv\cxcore.hpp(936) : error C2143: syntax error : missing '}' before 'constant' 5c:\opencv2.1\include\opencv\cxcore.hpp(936) : error C2059: syntax error : 'constant' 5c:\opencv2.1\include\opencv\cxcore.hpp(936) : error C2143: syntax error : missing ';' before '}' 5c:\opencv2.1\include\opencv\cxcore.hpp(936) : error C2238: unexpected token(s) preceding ';' (400+ similar errors, but I believe the answer should be the same, so only list 1 set here) I compared setting for proj_A and proj_B, made them identical, and find no improvement. proj_A works well, proj_B refuse to compile. May I know what's wrong? Urgent, need to get it solved ASAP! Thanks a lot!

  • Where is the money?

    - by Someone
    Big companies can afford higher salaries but it is harder to get noticed. Do you think that a talented programmer or somebody who is training himself to be really good could make more money in smaller companies? I think smaller companies have a lower average, but maybe great programmers can get much more. What do you think?

  • MSVC 2003 doesn't see any definitions from a nested include file

    - by ezpresso
    I have a piece of code with COM class declaration as follows: #include "PathTypes.h" MIDL_INTERFACE("552C7555-0555-4444-BA86-56CF39AAFFFF") IPathCalc : public IUnknown { virtual HRESULT STDMETHODCALLTYPE GetLocation( /* [retval][out] */ GeoLocation* pLoc) = 0; virtual HRESULT STDMETHODCALLTYPE SetLocation( /* [in] */ GeoLocation* pLoc) = 0; ... }; Below is the contents of PathTypes.h file: #if !defined(PATHCALC_TYPES_INCLUDED) #define PATHCALC_TYPES_INCLUDED #include "libastro/AstronomyStructs.h" #endif And the libastro/AstronomyStructs.h from an external cross-platform library: #ifndef _ASTRONOMY_STRUCTS_INCLUDED #define _ASTRONOMY_STRUCTS_INCLUDED typedef struct { double lattitude; double longitude; } GeoLocation; ... #endif /* _ASTRONOMY_STRUCTS_INCLUDED */ When I'm trying to build this code with g++ everything goes well. That's not the case with MSVC 2003 which returns error C2061: syntax error : identifier 'GeoLocation'. Seems like MSVC doesn't "see" the definitions from the libastro/AstronomyStructs.h file. When I replace #include "PathTypes.h" with #include "libastro/AstronomyStructs.h" the code compiles without errors. How to make MSVC 2003 to actually "see" the definitions from the nested include files?

  • List iterator not dereferencable?

    - by Roderick
    Hi All I get the error "list iterator not dereferencable" when using the following code: bool done = false; while (!_list_of_messages.empty() && !done) { // request the next message to create a frame // DEBUG ERROR WHEN NEXT LINE IS EXECUTED: Counted_message_reader reader = *(_list_of_messages.begin()); if (reader.has_more_data()) { _list_of_frames.push_back(new Dlp_data_frame(reader, _send_compressed_frames)); done = true; } else { _list_of_messages.pop_front(); } } (The line beginning with "Counted_message_reader..." is the one giving the problem) Note that the error doesn't always occur but seemingly at random times (usually when there's lots of buffered data). _list_of_messages is declared as follows: std::list<Counted_message_reader> _list_of_messages; In the surrounding code we could do pop_front, push_front and size, empty or end checks on _list_of_messages but no erase calls. I've studied the STL documentation and can't see any glaring problems. Is there something wrong with the above code or do I have a memory leak somewhere? Thanks! Appreciated!
