• Visual C# Create updates of my Setup project…

  I make a Setup Project in Visual Studio 2005 for my application. All works well but when I’m going to distribute an update in a new builded version of my application my clients have to first uninstall my application and then reinstall the new one.

• .NET Development Connectionstring

What is the best way to solve this issue Should i work with the machine.config (If yes... How...) Kind regards D ...Show All

• .NET Development Disable all interupts

  Hi , How can i disable all hardware interrupts Thanks. Well, IIRC, this would require that your code was running in Ring 0, which would mean that if you were doing this in Windows, .NET is out, you'd have to write it using C++/assembler or some such system-level language. In addition, disabling all hardware interrupts would mean that most device drivers would fail, and the OS would come crashing down around your ears. Hardly an ideal situation, what are you trying to do ...Show All

I know that you can "re-expose" functions ahta re hidden by the derived class by using "using BaseClass::FunctionName". However, I can't do it with base constructors... it goes something like this: class BaseClass { public: BaseClass( int i ) { cout << "Base: " << i << "\n"; } BaseClass() { cout << "Base\n"; } void print( char *str ) { cout << str; } }; class DerivedClass : public BaseClass { public: DerivedClass( float f ) { cout ...Show All
