Is there a way to have CodeDom put using statements before the namespace.
The msdn documentation says add namespaces imports to the CodeNamespace.Imports collection. This puts them inside the namespace (which makes sense, since your adding them to the namespace) namespace Foo { using Bar; //Code } However the rest of our code base has using statements outside the namespace: using Bar; namespace Foo {...

Creating app data on first use
I once read somewhere that apps should not copy data while doing an installation but rather all data creation must be done the first time the app is used. Q1: Does this apply to Windows Mobile apps also? Q2: Is it not okay then to copy a blank database to the \appdata\product\ folder and populate it when the user uses the app or must I...

Add section to configSections using existing ConfigSection type
I have some application settings that I'd like to add to my configuration file, but I'd like to group them outside of the normal "appSettings" section. My thought was that I would just create another "section" element within the "configSections" node of the config file, setting the "type" equal to "System.Configuration.AppSettingsSection...
WinForms checkboxes do not respond to plus/minus keys - easy workaround?
On forms created with pre dotNET VB and C++ (MFC), a checkbox control responded to the plus/minus key without custom programming. When focus was on the checbox control, pressing PLUS would check the box, no matter what the previous state (checked/unchecked), while pressing MINUS would uncheck it, no matter the previous state. C# winfor...

We are migrating our web sites from Win2003/IIS6 to Win2008/IIS7. Our .NET code is in a WAP form with compiled binaries. I do dev work on a Win7/IIS7 box so had to learn early how to set up HTTP Handlers in this newer environment. What I have that has worked fine on my box is: <system.webServer> <handlers> <remo...

Hello, I'd like to know if there is a way to create and launch a Remote Desktop Session on a Windows Server programmatically.

Design by contracts and constructors
I am implementing my own ArrayList for school purposes, but to spice up things a bit I'm trying to use C# 4.0 Code Contracts. All was fine until I needed to add Contracts to the constructors. Should I add Contract.Ensures() in the empty parameter constructor? public ArrayList(int capacity) { Contract.Requires(capacity > 0);...
Is there a .NET class that represents operator types?
I would like to do the following: *OperatorType* o = *OperatorType*.GreaterThan; int i = 50; int increment = -1; int l = 0; for(i; i o l; i = i + increment) { //code } this concept can be kludged in javascript using an eval()... but this idea is to have a loop that can go forward or backward based on values set at runtime. is...
Hitting a memory limit slows down the .Net application
We have a 64bit C#/.Net3.0 application that runs on a 64bit Windows server. From time to time the app can use large amount of memory which is available. In some instances the application stops allocating additional memory and slows down significantly (500+ times slower).When I check the memory from the task manager the amount of the memo...

explicitly refer to a class without a namespace in C#
The code I'm working with has a class called Environment that is not in any namespace. Unfortunately if I am in a class that imports the System namespace, there is no way to refer to the custom class called Environment. I know this was an unfortunate choice and should be refactored, but is there any way I can explicitly refer to the co...
