• SQL Server Looking for table design pattern for different value types

  Hi, I need to store a list of parameters in a database. Each parameter has a name, description, comment and a value. Easy so far. However the values are of different types. Each individual parameter has a value which may be of type int, decimal, string, boolean, custom type etc. Which table design pattern is most appropriate We have a heated in-house discussion and I need supporting arguments. Options explored so far: 1) (De-)serializing the value to a string-type. 2) Adding a column for each type, using only one column at a time. 3) Adding extra value-tables, one table for each type. The disadvantages for each option are obvious and the basis for our discussion. Your help in this matter will be appreciated. Regards, T ...Show All

• Visual C# Unable to debug C# solutions

  I'm using Visual Studio 2005 Pro. This problem is repeatable with archived code on backup discs as well as new solutions. When I attempt to run my apps in Debug Configuration with breakpoints, I get the message: the following module was built either with optimizations enabled or without debug information.

• Game Technologies: DirectX, XNA, XACT, etc. Learning a programming language AND game programming concepts simultaneously a pipe dream?

  I'm tryig to learn C# programming with the aim of creating games, but boy is it a struggle. I think the stumbling block for most people (and I include myself in this group) whose primary interest in programming is games related, is that a large conceptual leap is required between document-based programming and real-time programming - and there simply isn't any sufficient discussion or tutorials explaining the fundamentals of the concept to ease the transition. The basic problem is anyone who starts out learning a language like C# pretty much finds themself with nothing but books teaching the language from the perspective of programming forms, event-handlers, interacting with controls  and basically looking at exer ...Show All

• Visual C++ Specify a DefaultValueAttribute for an enumerated type property

  How does one specify a DefaultValueAttribute for a property of an enumerated type None of the constructor for DefaultValueAttribute take a System::Enum as the type of its parameter. The compiler does let me specify an enumerated value for the enumerated type but it must treat this as a System::Object instead. Try creating a CLR Class Library, add a Component Class, then add your code above to the component class. Build the CLR Class Library. Finally double-click on the Component Class header file to open it in Design mode. What do you see Now go to your component class code for the DefaultValue attribute and instead of: [System::ComponentModel::DefaultValue(Type1)] change it to [System::ComponentModel: ...Show All

• SQL Server Problem b'ocz of using diff tcp\ip port

  we have two servers say for eg sql server A and sql server B. Recently we changed the port number of server A to XXXX. Also server A was linked with server B. Earlier [i.e server A with default port] databases of server A were accessible from server B. But after changing the default port of server A, we could not able to access the databases of server A from server B Manick: You might need to add an ALIAS to the CLIENT NETWORK utility on server B for server A. I'm not really sure about this one, but it is a fast and easy check. Dave ...Show All

• Visual FoxPro Returning control from a modelless form.

  Hi; I have a form which displays a text file in an editbox. I call this form from a PRG which has a window defined. If the form's WindowType property is set to modal, the form works fine. If I change it to modeless, the form returns control to the calling prg but the active window stays the form itself. How would I keep a form modeless but return the active window to the window that called the form I hope I make sense... Thank you all. A variety of Modeless forms (browsers, lists, etc.) have various solutions you can work with in crude fashion (which your user won't care) I've (personally) disabled everything but "the calling form" during the call: i.e ...Show All

• Visual C++ cout and operator<<

  This code: char arr[] = "Hello" ; cout << arr; //displays Hello cout. operator <<( arr ); //displays the address of the H I had always thought that these two statements were equivalent. There is apparently a detail that I have overlooked. Since arr is the address of element 0, which is a char,then both statements need to call ostream::operator<<(char*). Right Why do the displays vary Shouldn't they be the same These two statements are not equivalent. The first statement considers both member operators and global operators while the second statement only considers member operators. As the operator that takes a const char* (or const wchar_t*) only exists as a glo ...Show All
