I've got some properties defined currently that tell me what environment the app is running in (i.e. "Development", "Testing", "Production", etc.), whether the user is an administrator, etc. It would seem logical to get this info from something like ...

I'm using the DevExpress Xtra TreeList control to display a hierarchical set of questions and responses - think of a complex survey form, containing sections, subsections and a variety of questions. The form is working in unbound mode, with no dataset nor any databinding. As a part of the information displayed for each question, some ...
I am sure there is a clever way to handle this, but I just can't get it right in my head. Here is the scenario: I have a base class with about 30 properties. Say that I have a property on this class called Type. For a subset of the instances of this class, I want to add a few more properties based on the Type property. In this case...
Is there any way to get the value of a SecureString without comprising security? For example, in the code below as soon as you do PtrToStringBSTR the string is no longer secure because strings are immutable and garbage collection is non-deterministic for strings. IntPtr ptr = Marshal.SecureStringToBSTR(SecureString object); string valu...
We currently have a SVN repository that we store our sourcecode in. We have a large range of projects in there (hundreds) and multiple common libraries etc. It all works quite well but it's non-standard in structure. Initially we were aiming for the standard "Trunk\", "Tags\Tag_1.0.0\" style model but the problem we had was that the rel...

I'm trying to play around with UPnP. Specifically, I'm trying to browse the content library of a PS3 Media Server. I tried upnp.dll (a COM library that ships with windows) and found it easy to use. I can discover devices and look at their services pretty easily, however it throws an exception when trying to access the services of the m...

I am refactoring an old program to use VS2008 (instead of VS2005) and the 2003 Crystal Reports merge modules no longer work on the client machine. I am using the CR version bundled with VS2008. Neither the CR10 merge modules downloaded from the SAP site work, nor the CR x86 msi. Could not load file or assembly 'CrystalDecisions.Windo...
Hi, I'd like to write an application that reads USB MIDI data from my midi piano and quite possibly anything else MIDI I can find. Looking for a library that works with .NET and also allows me to 'intercept' this data even if another application is using the MIDI. Thanks ...
It's a common sense when you are developing a big silverlight application that break it into many small components, to make the original XAP file relatively small and dynamically load the necessary DLLs from the server side on demand. An easy way is to download(From WebClient) the dll in the program in the runtime accroding to the URL s...
