Visual C++ Avoiding compiler complains about redefine variables???
Hi all: When I am writing C++ program, I need some global variables and structs to be visible from many files. But the compiler always complains that variable is already defined somewhere else. The problem seems to be caused by not #include file properly, but is there a good solution to avoid this irritating problem happen please Here is an example error message: Topology error LNK2005: "int COLUMN" ( COLUMN@@3HA ) already defined in ParticleSystem.obj Topology error LNK2005: "float UNIT" ( UNIT@@3MA ) already defined in ParticleSystem.obj Topology fatal error LNK1169: one or more multiply defined symbols ...Show All

Visual C++ VC++ 2005 doesnt compile, when non-startup project header is changed...
I have five projects in my solution. First four creates static lib and the fifth is exe file that uses those libs. The fifth project is set as startup and dependent to others. Whatever file (cpp, h) is changed, compilation occurres after F5 (build project) is pressed. I can also change something in cpp of the dependent project and it is also compiled. The problem are any changes in header files of dependent projects. VS just saves them, but writes: " ========== Build: 0 succeeded, 0 failed, 5 up-to-date, 0 skipped ==========" to the output window and compiles nothing. I tested this in VS2005 prof and VC2005 Express. Both have the ...Show All
Software Development for Windows Vista Development on Vista
Hi, What are the development tools that can currently be installed and used on Vista 1. Can I use VS05 RC1 2. Can I use VS03 3. What SDK do I need to use I am trying to setup a development environment for C++ on Vista and any help would be appreciated. Thanks. Hi, I going to assume you are using Windows Vista Beta 1. You should be able to use VS RC1 or VS 2003 (RTM). For now, you should use the Platform SDK for Server 2003 SP1. There will be a Beta 2 SDK going out the door with Windows Vista Beta 2. Thanks, Chris ...Show All
Visual C# checked keyword usage
I am having some difficulty understanding the checked keyword usage as it has been described in the text I am using. My understanding is that the checked keyword checks for overflow on a given datatype and throws an appropriate exception if an overflow is encountered. That being said, I have the following code that I am testing. The enum type is declared outside the Main routine and it is assumed that the myByte value contains a valid byte value. enum orienation : byte { north = 1, south = 2, east = 3, west = 4 } orientation myDirection = checked((orientation)myByte); If I enter 1, 2, 3, or 4, I expect everything to work wel ...Show All
Visual Studio 2008 (Pre-release) How do you read a lambda expression?
Hi All, I am trying to figure out how to read out loud a lambda expression. For example if I have the following i => (i %2) == 0 or c => c.Age < 50 etc. How would I read them to my children Cheers, Clint I think how a lambda expression is read depends on the context in which it is used. For example, In numbers.Where(num => num < 5), the lambda expression is a predicate, so the lambda can naturally be read as "num where num is less than 5". In numbers.Select((num, index) => new {Num = num, InPlace = (num == index)}), the lambda expression is a projection selector, so I would read i ...Show All
Windows Forms OpenFileDialog "hangs" on Windows 2000
I have a WinForms remoted application using a simple OpenFileDialog control. When I instantiate the dialog, the program hangs and never responds. This only happens on Windows 2000.

.NET Development Processes + Sub Processes
Hi. I know how to get a list of processes. I want to be able to "follow" or "trace" a particular process. Now, the way my application works is that if the user enters a url, it launches the url in IE. That's all very well. This will be 1 process as IEXPLORER. Now depending on the url, if the url say, is a link to a live stream, the stream could be launched in Windows Media Player or some other 3rd party program - whatever it is, this will be another process. IE will nicely open this/execute this for us. That's great. However I want to be able to know or find out what IE launched as another process of it's own - ...Show All
Smart Device Development Type Load Exception
Hi, I have this occasionally re-occurring problem which has just re-appeared and feel its time I go to the bottom of it... A project which previously ran OK now throws a System.TypeLoadException with following details... Additional information: Could not load type Microsoft.VisualBasic.CompilerServices.ProjectData from assembly Microsoft.VisualBasic, Version=7.0.5000.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A.

In the bin folder of my project I do have an assembly called Microsoft.VisualBasic but I'm not sure how it got the ...Show All
Windows Forms Button Text and Image depression
Does buttons with image embedded on them synchronize both text and image depression while clicking them in .Net2.0 I could find that when a new project in VS2005 is created and the form contains the button control, the look and feel at runtime satisfies the requirement. However, when I use a project originally developed in VS2003/.Net1.1 & now migrated , placing a button from .Net2.0, the run time does have the same problem. I know what you mean. When I first got VS2005 Beta I notices that things like CProgress Ctrl and buttons have a different look and feel. I think it has something to do with the ...Show All

.NET Development How to re-display user entered values in a DetailsView control?
When the user enters data in a DetailsView (Edit or Insert) and posts the page to the server, is there a way to redisplay all the values entered by the user if the data posted by the user fails validation on the server side (not on the client side). Operations like e.Cancel or e.KeepInInsertMode do not re-display the user-entered data.
