  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.

• simon burgess Localizing AfxMessageBox, "Yes", "No" etc.

  I have an MFC / C++ app in Studio 2005 that supports 10 languages using MBCS for Chinese. I can change the language of my GUI by calling SetLocale for each thread and the dialogs and CString strings are then loaded with the correct language. But any calls to AfxMessageBox get the English title (on XP English) of the application and Yes / No / Cancel buttons in English. The CWinApp has a member variable with the app title, so I can reload that. But I haven't figured out how to get the Yes / No / Cancel buttons to change language too. Any ideas I feel a bit silly.  I based my response on this KB (they mention it will start working as of windows 2000) http://support.microsoft.com/kb/152670 I shou ...Show All

• UncleSam89 Redistributing with SP1?

  This has already problem been asked and answered, but I couldn't find another post or article to this effect. I installed SP1 for Visual C++ Express Edition yesterday. Installation went smoothly, and my apps compiled and ran fine. However, when I moved my apps to another computer I got the error "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem." I checked to see if the VC 2005 runtime( availble here ) was present and installed, and it was. I finally concluded that SP1 requires a different redistributable. I have everywhere on MSDN but haven't yet found it. I also searched on my computer, but I couldn't find it there either.

• Stephen Turner COM newbie question

  when i use COM objects from C++ i need GUID and interfaces definitions.. i usually get them from an header. I noticed also that when i add a reference to a COM object (dll) in a C# project, the enviroment get directly all those informations about classes and interfaces. this suggest me that i could use COM objects even without headers. So my question is, it is possible to retrieve guids and interfaces definitions from a com object thanks to everyone in advice :) C# IDE does this by reading COM component type library. To to the same in C++ use #import directory with COM Dll name. It reads type library and generates wrapper C++ class which can be used by client code. thx, ...Show All
