      • Hi, You may remember my first post ( Outa This Operating System ), previously posted. I asked for code to run outside Windows with C#. I was told that it can't be done with C#. I since have a solution to the big "no-no" and a new question. I have found out about apps that claim to convert .NET applications from .NET to non- .NET (like "Xenocode Starter Kit 2007" ).

      • Hi, I have files in various subdirectories that I want to include in the Solution Explorer. It is getting a little tedious to "Add Existing Item" with a link (sometimes I click the button before changing it to "link" whereby I have to delete the copied file - bad UI design IMO). The files appear as a flat list in the explorer which is also a pain. I've discovered I can use <CSFile Include

There are tons of those really fat books that have huge amounts of whitespace and chapters that are so simple that it is insulting to read. I've gotten to a point in my career where I buy the thinest book on a subject because the fat ones are jun

I also have a user control in a separate assembly; some of its methods require enumerations defined in the core library assembly as parameters. This user control is to be used in a VB6 application.

Originally, I wanted to have a service change a HKEY_CURRENT_USER Registry Key, but seeing as you needed to call an API to do it, and I didn't know what to call, and with what parameters, I decided just to have the service run a windows application, and it would change the keys\values, because the service is running at local system, with Allow Servic

      • I am either not understanding how the IS operator works or how the FOREACH loop works. I found some C# code that creates 1 object of 4 different derived classes (see code below). Those 4 objects are assigned to variables of an array of the "base class" type. A FOREACH is used to iterate the array. The FOREACH variable is the "base class" type also. In the FOREACH loop, t

      • Hi all, What's the point of casting to interfaces, when you can invoke the members directly, like so: Box b = new Box(); b.Extrude(); b.Chamfer(); instead of: IEditable ed = b as IEditable; b.Extrude ( ); b.Chamfer ( ); Since intellisense shows me what I can access, I don't have to worry about using nonexisiting members Thanks, Aw

Apparently, if you use SetLength(32 * 1024 * 1024 * 1024), and seek near the end, all is good... until you try to Write to it. Once you begin your write, the file has to be filled up with some data as it's all empty space, which is semi-obvious. But it does this in 1K bl
