• MarnieV "new" event handlers

  Given this declaration: Button myButton = new Button(); void myButton_Click( object sender, EventArgs e ) { MessageBox.Show("Click"); } What is difference between doing this: myButton.Click += myButton_Click; and doing this myButton.Click += new EventHandler( myButton_Click ); I've been doing it the simpler ( first ) way and I haven't had a problem (yet ), but I've noticed that most documentation I've read has it the other way, creating a new EventHandler. I'm not clear on what the effect of creating the new event handler is, and I am yet to discover what "The Bad Thing" is that's going to happen if i do i ...Show All

• Rykin Poe keyboardbuffer c#

  Is there a way to see in c# what is in the keyboard buffer (number of characters and their values) When i am in the eventhandler keydown I want to know when I leave the keydown eventhandler if there are still chacters being pressed (so what is in the keyboard buffer). There is no way to look in the buffer because this is abstracted from you by the windows kernel. There are however low level keyboard messages generated by the kernel. To get these you have to use the Win32 API. But listening to your problem it doesn't sound like a good idea, because you want to stay in the event handler and wait for the events to happen. This will hold up your application and the messageloop gets clustered. You could better try to handle your prob ...Show All

• IlkerTunca Compiling under dualcore systems

  Is it possible to get Visual Studio to use the full capabilities of multiple processors and/or dualcore processors I have a project in Visual Studio that takes 4 - 5 minutes to compile, and during the entire time, it's only using 50% of the available processor power. Obviously it's going to take time for the compiler to be upgraded to support multiple cores and multiple processors, but is it possible to at least compile two files at the same time - a copy of the compiler running on each core/processor One of the projects in question is a Visual C++ project with just over a hundred cpp files. The machine used to compile the project is a AMD X2 4800 with 2GB of RAM. Only Visual C++ can do multiprocessor ...Show All

• ChrisMcCabe Late binding in C# - How to pass an object and yet use hardcoded properties?

  Hi, I will use an example to describe my problem: I have two objects - Say Student and Teacher. The two objects share some properties - Say Name and Birthdate I have one method that lists person name and birthdate. I need to pass an object and yet use the properties - Something like this: private void ListPersonInfo(object person) { Console.WriteLine(person.Name, person.BirthDate) } The above does not compile since at compile time the Name and BirthDate are properties of their respecitve objects and are not properties of the Object class. I don't want to use two methods one for teachers and one for students. I also know that it is not a good OO practice to pass plain objects like this and I don't want to us ...Show All

• ShadowRayz Getting shortcut properties

  Is it possible to get the values of properties from a shortcut that launched an application I've created a shortcut for an application and after right clicking on it and selecting "properties" I can see there are several items in the "shortcut" tab. What I'd like to be able to do is get the value of "Run:" in the application, so I could get it to start either normally or minimised. Is it possible to read these values Thanks, Stu not sure I quite follow. You would need to implement the IWSH interface to read desktop shortcuts.... if you are trying to pass arguments into your application, then this would be better than to read the shortcut and checking to see what the sho ...Show All

• Bagles1 Closing files (without saving) is slow

  I've seen other posts about the VS 2005 C# IDE being slow for typing or when saving files, but for me both of these cases are ok. But *everytime* I close a file (whether or not it needs saving), it takes several seconds. If I open up the "Windows" dialog to close several windows, it can take minutes. I've tried the obvious like defragmenting the HD, not having too many files open at once -- doesn't matter. Any suggestions Thanks! Can someone help me interpret the filemon output. I filtered on the devenv.exe process, and replaced the (rather lengthy) path with [localpath]. What I notice is that 3 seconds is spent on these two lines (I can't tell if the time is spent on the first line or the second line -- d ...Show All

• nightchaser library not registered error

  Hello, I hope someone will have an answer to this question... Using VS. Net + C# I have a a console project called implementer that communicates with another addin project. Both are supposed to send and receive a "struct" that holds a hashtable to store/change info. I got the addin to show up right and it starts listening to the events been triggered by excel. In one of the events, the addin class, via invocation, is supposed to instantiate an instance of the struct and pass it to the running instance of the implementer class which changes and modifies the info in the hashtable of that struct. when trying to send that struct (which is a dll file by itself but added to both projects as reference) I get the error message s ...Show All

• Latso Make end of statement ";" optional?

  I think microsoft should make the end of line statement, (i.e. the ";") optional. If you program VB.net like I do and is inevitably forced to write/read C# code, having to write the ; after each statement is annoying. I know C/C++/java etc all have it but in an enviroment like Visual studio where the IDE makes life so much easier the end of line statement is unnecessary. Who agrees with me Gabriel Lozano-Moran wrote: The reason that VB was popular was because it was an easy to learn programming language. Because it was so easy to learn a lot of hobbyists that didn't have proper training could "develop" software often using bad practices like Cowboy Programming and using bad practices without realising that ...Show All
