• Visual C++ hangman project

  Hello, I'm somewhat new to C++. I am taking a class on it in college, but the teacher doesnt like to explain things very well. Basically her idea of helping us learn C++ is this: "this is how you start all your programs in this class: #include <iostream> using namespace std; int main() { } " She never explainted even what "#include <iostream>" or "using namespace std;" ment. So, this brings us to my question. I'm trying to write a c++ program *for a project in class* that is a hang man game. The hangman is stored in a character array. The user is able to input a word into a 25 character array "char word[25];". There are a couple of things I need to do. the first thing is, I need to know h ...Show All

• Visual Studio 2008 (Pre-release) Loading November CTP for WPF and WCF on production system

  Generally we have a practice of not loading CTP or Beta software on our production systems we use to write code with every day. However we would really like to have access to the WPF features in this CTP and I notice that the download page does not have the normal, do not load this on a production system caveats. Is there any advice on using the November CTP WPF/WCF tools on a production system Thank you in advance.

• Visual Studio Team System Where is the Change Source Control... menu item?

  I have a project which (somehow) I've managed to add to the TFS source control without binding it correctly to the repository. This means that files are not automatically checked out when I edit them. Everywhere I look for a resolution to this says, no problem, just go File->Source Control->Change Source Control, and re-bind the project. Unfortunately, I don't see this option in the menu. I've used Tools->Customize... to add the option to the menu, but it's just greyed out all the time. Can anyone please help me with this really annoying problem Thanks in advance, Matthew Yes, it is. That (apart from None) is the only option available. I vaguely remember having a problem like th ...Show All

• SQL Server calling user-defined functions in another DB

  I have a number of databases that require a set of common functions. I'd like to place all those functions in a central DB. I'm having trouble calling them using the syntax FunctionDB.GetParamLength() for example, which works within the FunctionDB database. Any ideas/suggestions I really don't want to maintain seperate copies of the functions across 5+ databases. Should work for you like this here: USE Master GO CREATE FUNCTION dbo .

• Visual Studio 2008 (Pre-release) VPN vs. WCF - Need advice

  I have a scenario for an upcoming project where I'd need some advice from you. Here is the prerequsites: 1 - A server (SQL and probably IIS) will be hosted on some kind of serverhotel. This SQL server will hold all application data. 2 - The application accessing the SQL server will be a WinForms (c#) application. 3 - The application will be used by 5-15 different customers. Each customer will have there own instance of a database on the SQL-server. The reason for why the SQL-server isn't located at the customers site is that the customers do not want the overhead of administrating it. 4 - The customers will have at least a 2Mbps connection to the internet. So, I have been thinking of two different solutions: 1 - Use WCF so that the W ...Show All

• Windows Forms version question

  Hi All, Quick question, I am publishing with changes to Revision number and I am upto 19 and in the publish screen I see the publish version as 1.0.0.19, but when I go to the client install box and I see the application version it shows 1.0.0.0 even though they have the latest build. Is there something I am overlooking Thanks in advance. Publishing has it own versioning, to keep them in sync you need to update the AssemblyInfo in Properties of your project. In there you should find [assembly: AssemblyVersion ( "1.0.0.0" )] [assembly: AssemblyFileVersion ( "1.0.0.0" )] You just need to update them ;-) HTHs, James ...Show All

• Visual Studio 2008 (Pre-release) Memory Leaks/Garbage Collection and WPF

  In our app, each time we open a particular window and close it, our memory usage increases. Through profiling, we can see that this window is not ready for garbage collection and tracked down our problem to this: we’re using a command pattern to bind to context menu items. Our command instances are each a long-lived object that is managed in an inversion of control container (i.e. ultimately referenced from a singleton). When the command is bound to the menu item, the menu item subscribes to the command’s CanExecuteChanged event. The resulting event handler reference from the command to the menu item still exists. The menu item in turn has a reference to the window in it's "EffectiveValues" collection (index 0), and ther ...Show All
