• Visual Studio Express Editions File I/O problem with V C++ 2005 Express

  Hi, I use a really simple macro for logging to help me debug, and I can't seem to get it to work in C++ 2005. I get these errors from the macro below, which works fine in Borland :[ Very new to C++ -- does anyone know what I'm doing wrong Is there a better way to do IO in VC++ 2005 Thanks!, Jim #include <iostream> // I/O #include <fstream> // file I/O #include <iomanip> // format manipulation #define LOG_DEBUG( x ) { \ std::cout << x << std:: endl; \ ofstream fout;\ fout.open("C:\\myfile.txt", ios::app);\ fout << x << "\r\n";\ fout.close();\ } 1>------ Build started: Project: Engine, Configuration: Release Win32 ------ 1>Compiling... 1>Engin ...Show All

• Visual C# Indexed properties and IndexOutOfRangeException

  Hello, The Visual C# code analysis tools tells not to throw IndexOutOfRangeException exceptions. However, the C# Indexed properties Sample throws it (and no other sample throws any exception). So, what should I do Throw ArgumentOutOfRangeException instead Supress the code analysis warning, although the online help explicitly tells not to Do not throw any exception and return a default value instead I'd follow the general rules of the framework. The collection classes throw ArgumentOutOfRangeException . The reasoning is that the argument that was specified is out of range for the given array/list. The IndexOutOfRangeException is designed for the CLR when indexing beyond a memory bu ...Show All

• SQL Server Linked Server in Management Studio

  I have created Linked Servers for Access databases. SPs are able to select data from the Linked Servers. In Management Studio, the General Properties are greyed out and therefore can't be modified. I need to modify the Data Source to connect to different Access databases. Can't find a way to do this with a SP either. Searches seem to indicate I should be able to modify the properties using Management Studio. Management Studio does not display the list of tables, etc. in the Access database as Enterprise Manager did for a Linked Server. The data source is on a mapped drive. The definition: /****** Object: LinkedServer [ACCESS GENERAL] Script Date: 02/05/2007 11:56:43 ******/ EXEC master . dbo . sp_addlinkedserver @server = ...Show All

• SQL Server Linked Server Problems from SQL2005

• Audio and Video Development Scaling still does not affect the renderer dimensions

  Hi I asked about this problem and got an answer that it was fixed here: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=718158&SiteID=1&mode=1 But it still seems to do not work as it should. The problem: I built MFT that performs 2x scaling with input type YV12, NV12 or YUY2. To test it I use a player that based on the PlaybackFX SDK sample. When the output type is YV12, everything is OK and I get the scaled dimensions from the renderer using GetNativeVideoSize(). When the output type is NV12 or YUY2 the GetNativeVideoSize() returns the original dimensions of the video and what I see is a quarter of the frame. I also tried to set it manually with the correct size but it only stretched the quarter and did not display the ...Show All

• Smart Device Development Differences between DotNet Compact Framework 1.0 RTM and 1.0 SP2

     Can anybody help me with the following problem I have been developing a Windows CE 4.2  Symbol handheld device which uses Scanner and RF hardware. The application is written in VB.NET and uses .NET CompactFramework Version 1.0 RTM (2002 - version 1.0.2268). It communicates with a Server Application via Tcp/Ip Sockets. When using this version of the CompactFramework 1.0 RTM (1.0.2268) the device retains it's connection with the Server when the device is either turned off or if it timesout. When powering the device on again, the connection with the server is still maintained. When Cold Booting the device and loading all files as before, except with a newer version of the .NET ...Show All

  I'm trying to wrap my head around the use of effects and their use in rendering models and primitives. The sample code to render a model "m" looks like the following: foreach (ModelMesh mesh in m.Meshes) { foreach (BasicEffect effect in mesh.Effects) { effect.EnableDefaultLighting(); effect.View = view; effect.Projection = projection; effect.World = MyWorldRotation * mesh.ParentBone.Transform * Matrix.CreateTranslation(Position); } mesh.Draw(); } While the sample code to render a primitive looks like this: basicEffect.Begin(); foreach (EffectPass pass in basicEffect.CurrentTechnique.Passes) { pass.Begin(); graphics.GraphicsDevice.Vertices[0].Set ...Show All

• Visual C# Using WMI to get Current Logged On User

  I am attempting to use WMI to obtain the current logged on user of a remote computer. I query W32_ComputerSystem and look for the value of UserName.

• Visual Studio 2008 (Pre-release) XAML inheritance?

  I made a user control with several buttons on it (call them A,B,C), but wanted to make this control a so-called "base class" for other user controls that would extend such a class so that the derived controls would all have the same common set of buttons (A,B,C) but would have their own unique specializations (i.e. the usual use of inheritance). I haven't had success implementing this relatively simple concept in XAML/C# with user controls... suggestions What is the correct way to do such a thing Is there any elegant way to inherit from another XAML/C# class and use its members For some reason, I assume there has to be a way to do this since you can do it in just about any language, but no one ...Show All
