• Visual Studio Express Editions Please Help: Unhandled exception with SEC_WINNT_AUTH_IDENTITY_EX

  When I run the program I get the following error message. Unhandled exception at 0x77ec4683 in WMI.exe: 0xC0000005: Access violation reading location 0x00000200. I've determined that it is caused by the Auth structure but I do not know why. Can anyone figure out and explain what is the issue. I'm new to C++ on a whole, and I'm to the extent of my understanding. Here is a copy of the source code.

• Software Development for Windows Vista Audio Playback problems in Vista and Windows Server 2003

  We make a dll that is able to play any number of Audio files using subgraphs patched one or to any number of audio renderers present in the machine. It also does samplerate conversion and scales any bitdepth of sample. The problem is that on XP/2000 it works fantastic and when you try and run it on either Vista or Server 2003 it becomes unpredictable/unresponsive and you loose control over the subgraphs. I have trie reading all sorts of documenation and what others experienced but found nothing that explains or helps me to correct the problem. I suspect (pretty sure) the threading have been altered in the directshow but would like to have this confirmed and what im supposed to do about it. BMS-Joppe Mr G, Ive located ...Show All

• Visual Studio 2008 (Pre-release) Msg Keep Alive

  Hi guys, Does WCF perform any kind of connection keep-alive message scheme For example, if I have a service provider that takes a minute to do some stuff would I have to set the inactivity timeout to be greater than that or will the connection remain active as long as the service provider is performing the operation great forum by the way TZuge I think it is really depends on shape of the channel we are using,if it is request/reply channel,inactivity time will be triggered after we are done with call only. if it is one way channel,behaviour may be different,I will try to test this behavior some time this week -Thank you Madhu ...Show All

• Visual Studio Team System Cannot pass a GCHandle across AppDomains while using unit testing.

  Got a manage C++ class in a class library that uses unmanaged C++ lib. The managed C++ class handles callbacks from the unmanage C++ lib by a delegate "gcroot<MessageDelegate^> m_MessageDelegate". To invoke the delegate I use the call "m_MessageDelegate->Invoke(nMsgId);". This works without any problem when running applications using this class library but when testing the class library using unit testing I got the error "Cannot pass a GCHandle across AppDomains" when I invoke the delegate. i know that the 'Cannot pass a GCHandle across AppDomains" has been an issue in work item tracking. I wonder if this is your issue also or something similar. The following link is a list of bug Fixes in ...Show All

  I have one application and in that I have to show the waitcursor whenever any operation starts. NOw the operation starts from one class file. and it's not a form. to change the cursor we need to give the form or control reference. Now I want to use eventhandler for this. so whenever i need to change teh cursor i can raise one event and on that form application i can change the cursor. but i have read somewhere it's heavy to use eventhandler. don't use it for small purposes. Why it's heavy Can anybody tell me. I would gess that's because delegates in .NET are implemented as "multicast" delegates. So when you have the feeling to create a single pair of references (to the instance and to pointer), you in fact crea ...Show All

• .NET Development Conference app

  I want to create a conference software. I'm new to C#, I've worked until now with Visual Basic 6, Java and C++. The basic modules are: - video module - audio module For the video part I managed to sort it out... take pictures at every 10-20 ms with the webcam, save them and then send the files to the other end. Now the next thing... how can I send audio streams between 2 computers I'm thinking at the following algorithm: record 10 seconds then save it as a wav file and send it to the other end, but I think this is a rudimentary method and also I want to create the conference in real time . Can you suggest me something I just need a little push meaning some links that I could study. Thanks in advance. ...Show All
