Now unfortunately due to the fact that WinCE Usb Device Arrival / Removal exposes itself via WindowsMessages I have to ensure that a certain (non-UI) component is not created on a background thread. I would like to assert this via an exception but am lacking the code for the assertion. This component creates a MessageWindow* and uses it...

I'm having a strange problem - I have about 14.5 million bitmap images, that are supposedly uncompressed. I need to convert these bitmaps to JPG and store them in a database. When I use the classes provided in the .NET System.Drawing library to save the bitmap as a ImageFormat.Jpeg, the resulting JPEG is about twice the size of the ori...
In the application I'm working on, I've been trying to use the SaveFileDialog and OpenFileDialog for their customary purpose (saving and opening files.) However, the application can't support modal forms/dialogs without crashing because too many time-sensitive things happen on the thread that owns the UI. Rewriting the application to m...

I have a .net WinForms app with buttons that are displaying as XP style (rounded corners) at design time, but Windows 2000 style (square corners) at runtime. My desktop theme is set to XP style. I'm guessing there's an obvious setting that I'm overlooking. Thanks. ...

Using Linq To XML, how can I get the space_id value (720) from the xml below? I am reading this but I think the namespace in the xml is my stumbling block. <r25:spaces xmlns:r25="http://www.collegenet.com/r25" pubdate="2009-05-05T12:18:18-04:00"> <r25:space id="VE1QOjRhMDAyZThhXzFfMWRkNGY4MA==" crc="" status="new"> <r25:space_id>...
I'm new to Data Generation Plans in Visual Studio, but I googled a bit and can't find the answer to this question. I've made modifications to my schema on the database side (changed the size of an NVARCHAR field) based on data that was generated by a Data Generation Plan (a procedure broke because the field was too large), and now I want...
Basically I wanna know if all the types in a particular namespace implements a particular interface like IEnumerable. I know I can do: foreach type ... if type is IEnumerable ... But I don't wanna cast the type just to query if it implements an interface, because the cast will be thrown away either way. ...
I'm using C# (.Net 2.0), and I have a fairly large text file (~1600 lines on average) that I need to check periodically to make sure a certain line of text is there. What is the most efficient way of doing this? Do I really have to load the entire file into memory each time? Is there a file-content-search api of some sort that I could...
I wrote a dll in VS 2005 that will be loaded by another program that was developed in VS 2003. When that program tries to load my dll, it throws a System.BadImageFormatException: The format of the file 'Foo.dll' is invalid. I searched SO and Google, and it seems that the different version of .NET is the culprit. My question is: How do I...

I want to create a bunch of forms that all have the same properties and initialize the properties in the forms constructor by assigning the constructor's parameters. I tried creating a class that inherits from form and then having all of my forms inherit from that class, but I think since I couldn't call InitializeComponent(), that I w...
