• Visual C# Changing Type during runtime

  In response to my previous thread which can be read here , I've decided to create a new thread because although I mention this problem in my previous thread, this is a different subject. To recap, I have a class Shape, which will have many inherited types. In a class Physical, I have a Property which returns a Shape object. Many classes inherit from Physical, and each inherited class will need the capability of allowing the user to change the Shape Type during runtime. I came up with a decent solution, but was wondering if anybody knows, or can think of a better way(s) to solve this: [ BrowsableAttribute ( true ), ReadOnly ( false ), TypeConverter ( ty ...Show All

• Visual Studio Express Editions noob question: what do windows applications use as a db?

  sorry but I have this totally noob question. I'm completely new at writing windows applications, and want to learn. I have a book (sams learn in 24hours), and it briefly goes over ADO. My question is, besides writing to a flat txt file, what do windows applications use as a database Obviously your standard XP desktop doesn't have a db server, so how do programs save information I'm basically creating a database, but want it to be an installable program, not an MS Access db. But I'm having trouble figuring out what to do in regards to a DB. I see you can use localized db's inside VB, but I keep reading that the user would still need sqlserver express or is that wrong sorry, I must not have been ...Show All

• Visual C++ Sound Played every time I press Enter

  Hi, I'm quite new to Visual Studio 2005 and C++. I've developed a Windows Forms Application with the C++ visual studio, and every time I press the Enter Key in the running program, then windows makes a Sound. In some TextBoxes I have KeyPress Events, and in the called funktions I have: " if (e->KeyChar == '\r' )" with e being the System::Windows::Forms::KeyPressEventArgs. but the sound isn't bound to these TextBoxes it occures every time I press the Enter key. I would be very glad if someone could tell me how to deactivate this. Thanks in advance!! Ok I'll answer this one myself, for whoever is interested. I discovered, that you only have to set the Handled property to true, like t ...Show All

• Windows Forms Treeview dragdrop event ignores exceptions! HELP

  Hi, I have a windows.forms application in C# using a treeview with dragdrop capability, however I have found when an exception occurs in the DragDrop event and is unhandled, .Net ignores it (instead of showing the exception dialog) Attached I have some test code where I explicitly throw an exception in the DragDrop event, nothing happens!

• Visual C# Degraded performance in DevStudio

  About a week ago I began noticing a sharp decline in the execution speed of the Visual Studio 2006 at all levels. Even in the Editor Window when I make a change the cursor won't move until good 5 seconds later. I checked the CPU usage in the Task Manager and can see that even on small, insignificant cursor movements in the source code editor the usage is up to 13%. Anything more substantial brings it up to 100% in no time. It does not happen all the time but very often. I tried to figure out the cause of it. My app is getting larger but I do not think it is exceptional. The computer is very fast (3.8GHz CPU, Bus 800 Mhz and 2Gbytes memory). What could be the problem Thanks. The Studio has 6 projects. Only one of them is real ...Show All
