• Visual C++ no Code Snippets in C++?

  Somewhere I read that code snippets are not aplicable in C++ code. Is that true and why I only want to use snippets to insert documentation templates for classes, functions etc. at a first look I do not see any technical reason for not supporting that feature. Thanks for your help, Tobias No Insert Snippet, no Snippets folder in the VC folder and no Snippets editor. Perhaps it has something to do with C++ class declarations and method implementations normally stored in separate files ...Show All

• Visual J# Difficulty of porting to J# from Sun Java?

  I asked the same question in Sun's web site, which got me some cold faces. I hope folks here would be nice. i m only seeking an advice. my app was originaly developed under Sun's JDK 1.1.4, but as i kept adding more fetures on it, it has been optimised to a 1.4.2 app, and some parts of the code are using 1.5's. Due to the fact that my clients mainly use windows and they only like Word(no open office), and i find it's really hard to deal with Word using java, so i m thinking of building a native app for windows and by using the .net library, let me generate word document more easily. we are just small company, we dont have enough man power ...Show All

• Audio and Video Development Mpeg1 format support?

  Hello everyone, I was trying to rewrite the VideoSource example provided in the MF SDK as a mpeg1 source filter that output two streams (one for video payloads and one for audio payloads). In VideoSource::CreateMediaType() I was supposed to convert a AM_MEDIA_TYPE that presents a mpeg1 video payload media type into a IMFMediaType format, however, the MFCreateMediaTypeFromRepresentation() function does not seems to recognize the AM_MEDIA_TYPE and return E_INVALIDARG. Can someone gives me a hint about what is done in the MFCreateMediaTypeFromRepresentation() and is it currently possible for MF to do mpeg1 file payback, like mpeg decod ...Show All

• Visual C# How can i change string to font object??

  I am making a simple text editor using C#. And i want to change the font size of the text. I did it and stored the font settings in the registry, by converting the font object to string.

• Visual Studio Team System Single PC - Team Build Error - Build Machine Not Reachable

  I've setup the client, data and application tiers on the same machine - a Virtual PC called Dellone. When I try to do a Team Build an error message appears saying Build Machine Not Reachable. Why is this happening I'm following the instructions in the first Team Build Walkthrough - Creating a Build Type in Team Build.

The is displayed .", but the Team Project Settings submenu doesn't contain Build Configurations, just Groups, Permissions, Classifications and Source Control. I therefore attempted to set the Build configuration as follows: 1. ...Show All

• Software Development for Windows Vista Roles and WWF

  I've read the articles that Microsoft have published about the new WWF. I saw only in the article by David Chappel a few words about this issue. In People 2 People Workflows one of the major concernes is how flexible is Role resolution and Role assignment works.

• Visual Studio Team System HowTo Update AreaPath through OM

  Hi guys, How can we set AreaPath field through Object Model When the field is set, on save Work Item complains on AreaID field. There is no AreaID field defined in our WI. If it is system, reserved field, what should be its value Hi Leon,    The behavior you are seeing may be because of a bug in the beta2 workitemtracking code, where the format to set and get values in the Area Path field are different.
