• Smart Device Development __stdcall in VS2005 and linker error

  I'm trying to build a DirectShow filter for WM 5.0. There's no "Calling Convetion row" in the VS2005's property pages window so I wrote the command line option /Gz for __stdcall in the additional options box. But, the cl compiler ignored the option /Gz and linker show me the following errors: error LNK2019: unresolved external symbol "public: __cdecl CBaseFilter::CBaseFilter(wchar_t const *,struct IUnknown *,class CCritSec *,struct _GUID const &) error LNK2001: unresolved external symbol "public: __cdecl CRenderedInputPin::CRenderedInputPin(wchar_t *,class CBaseFilter *,class CCritSec *,long *,wchar_t con ...Show All

• Visual C# locking write access to generic list

  Hi, I have a generic list that is accessed within a method for write access, as well as in a timer triggered method. The problem is when the timer triggers at the same time as the other method is triggered I get a CollectionModified exception while iterating through the collection. Thus I'd like to know if there is any way to lock the write access to the collection while one method executes and accesses it Thanks, Tom ah, I only had it in the one method and forgot it in the timer method ... that's why I was wondering why it didn't work :) thanks ...Show All

• .NET Development .NET 1.1 in Visual Studio 2005

  I'm sure this might be a dumb question, but I thought I'd go right to the groups to hopefully get a quick explanation. I'm writing a client app in VS 2005 that references a web service I had written in VS 2003. The client app utilizes 2.0, the web service uses 1.1. I know that the two can communicate, but can I pull the web service project into the VS 2005 solution and still it will rely on 1.1 (because the hosting server is only 1.1 capable). Alright ... ready to discuss ... go! Hi! VS 2005 do not support 1.1 framework. But 2.0 is very compatible with 1.1 at source level, so you can simply recompile. Web service clients will not see ...Show All

• .NET Development Deserializing a *Node from an XmlSerializer written .xml

  Im in the process of trying to figure the best design for logging some Exceptions that may occur in my application *(due to legacy data).  I have basically created a class that keeps track of relevant bits of information about each exception and then uses XmlSerializer to log this to a file. I have no problem say, serializing an array of the same class, but, I've read that it's possible to deserialize a single node of the xml file, and I've been working a bit with the relative classes but haven't found how this is possible.... something along the lines of (pseudo code): node.deserialize   I'm trying to create a logger that  ...Show All
