I'm curious if there are any texts that can be recommended that actually discuss application architecture best practices with respect to the use of Silverlight in web applications. ASP.Net would be preferable, but I'm open to consideration of other technologies also. ...

I've got a DataGridViewCobmoboxColumn that has to be on the far right side of the screen. The items in the cell are wider that the cell width, so the dropdown list is also wider than the cell, so the user can see what top select. When the list drops down, the right side of the dropdown is not visible, and thus the scroll bar is also not ...
With the recent announcement of .NET 4.0 and Visual Studio 2010, it is becoming ever more difficult to keep track of what .NET Framework versions build on what version of the CLR and belong with which version(s) of Visual Studio. Is there a definative table that shows these relationships? ...
I have G729 encoded audio files. I need to programmatically convert them to WAV PCM (16bit 8kHz mono) in the flow of a tool that is doing other thing too. I have an executable that will do that for me. But spawning that external process every time I convert is too heavy on resources. Especially if I need many of them being done in parall...
I am trying to debug a strange issue with users that have LogMeIn installed. After a few days, some of my dialogs that my app opens can end up offscreen. If I could reliable detect that, I could programmatically move the dialogs back where they are visible again. Note: this has to work for multiple monitors and use the win32 API. Howeve...
This is in relation to this question I am hosting this WCF service in a custom service host. IIS is not an option.

I've implemented a .NET Web control that uses the callback structure implemented in ASP.Net 2.0. It's an autodropdown control, and it works correctly in IE 6.0/7.0 and Google Chrome. Here's the relevant callback function: function ReceiveServerData(args, context) { document.getElementById(context).style.zIndex = 300; document.getEleme...
I have a generic class in C# with 2 constructors: public Houses(params T[] InitialiseElements) {} public Houses(int Num, T DefaultValue) {} Constructing an object using int as the generic type and passing in two ints as arguments causes the 'incorrect' constructor to be called (from my point of view). E.g. Houses houses = new Houses(...

Backstory: I have a PKCS#12 (p12) certificate with a symmetric cipher (password) that I used OpenSSL to convert to a PEM; opening that as text I see it contains both a BEGIN/END CERTIFICATE section as well as BEGIN/END RSA PRIVATE KEY. The .NET Framework X509Certificate class only supports the "ASN.1 DER" format, so I used OpenSSL to co...
I have a managed Windows application that loads a managed C++ component that uses AfxLoadLibrary to load a third party component if present on the client machine. Once detected, I'm unloading the component using AfxFreeLibrary in an attempt to lower the working set of the managed parent application. The call to AfxFreeLibrary is succ...
