• JustPlayingAround System.Timers.Timer not elapsing

  I have a two timers in my service that will be reset after some work gets completed. The problem comes in if the service is left running for a few days, the timers will reset but then not elapse. The problem is that without the timers elapsing no work gets accomplished. Any ideas I don't think anyone can make a decent guess with the information you've provided. Perhaps you could show some code, describe more of the code context etc. I don't think that's the problem since I'm only experiencing this in one environment but in all others I'm not. Is there something that will be able to determine what is causing the problem since nothing is written in the event log. v ...Show All

• sunrunner Question about const_cast

  Here's round two of my silly questions.

• Manhattan How to include the System namespace?

  Hi, I'm trying to use the String.Contains method which is under the System namespace. without including the System namespace. It complains there's no such method, but if I try to include the System namespace as using namespace System; It complains there's no such namespace. Any suggestions thanks in advance! What kind of project do you have Is it managed Is it unmanaged If so, is it MFC based You can do that in an unmanaged project with STL. std::string has a method called find_first_of() that does just that. Can you explain what are you actually trying to do It seems to me that you only want to take String out of System What kind of project s this The error message I recieve ...Show All

• Dipendra error LNK2019 when compiling C++ app

  Hi, My problem seems to be with compiling my C++ app into an exe file. I can build the files fine. But, when I use debug to make the .exe file, it comes back with some errors (at end). What's weird is these are all methods being implemented or calling a method, nothing else, which leads me to believe that there is some option that I have to set. This error is something I have never seen before. Here is some source: status = RpcStringBindingCompose( NULL, // UUID to bind to. ( unsigned char *)( "ncacn_ip_tcp" ), // Use TCP/IP protocol. ( unsigned char *)( "192.168.1.100" ), // TCP/IP network, the same machine as server ( unsigned char *)( "9191" ), // TCP/IP port to use. ...Show All

• MartinMalek C++/CLI Compile Error

  Hi, I have some code that compiles and works fine in C++. I am in the process of attempting to use this same code in a C++/CLI project. Been working through various compile issues. This one is pointing me into the map, do not want to mess around with that code. Anyways, the error I get is, C3699: '&': cannot use this indirection on type xmlDictionary::DictionaryData. My class that I am working with is named xmlDictionary. DictionaryData is a struct, ref struct DictionaryData{ std::string value;// error here also ValueType type; }; The offending line of code is, std::map<std::string, DictionaryData> m_data; I am thinking it is STL related. Any direction would be appreciated. Thanks Jeff ...Show All

• Maarten Zaagman Number of threads known only at runtime

  I'd like my app to take advantage of multiple cores as they become more numerous in the future. I'd like to determine, at runtime, the number of cores and based on this launch the appropriate number of threads. I may also need to be able to access the threads individually from the UI. Is storing references to threads in a collection container such as Array or Map a good approach Unfortunately Environment::ProcessorCount is not always useful on a hyper-threading enabled machine where each logical processor (or core) that has hyper-threading enabled appears as two processors instead of one. If you are running 2003 on up you could use GetLogicalProcessorInformation to better interrogate the processor and ...Show All

• dwloeb77 This application has failed to start because the application configuration is incorrect

  Hi, I am just starting programming using Visual C++ 2005 Express Edition. I have had some limited practice in other languages and older versions of C++, so I have some idea whats going on but not much... Anyway I made a short program which perfroms a bubble sort on an array of numbers which the user enters (I know its nothing to write home about but its a start), it works fine on my PC and when I sent it to a freind who also had VC++ 2005 Express Edition it worked fine for him. However I then sent it to a freind without it (in a fairly poor attempt to persuade him to download it) , and my program didn't work on his PC giving the error: "This application has failed to start because the application configuration is incorrect". I was wo ...Show All

• Ludo Versweyveld "unresolved external symbol _main"

  I am getting this error after I try to compile a visual C++ dll file. It compiles OK but when I try to build it I get the error. If you add to your CPP file a fragment like void main() { } then maybe the linker error will disappear, but I do not think the resulting file will meet expectations.

• KrisK RT_RCDATA error in msvs2003 resource editor?
