Hi, I'm a programming student, and I've now had two classes in C#, this semester I'm taking my first C++ class. Out of curiosity, is it possible to call a C# application from a C++ application? If so, is it also possible to check if the computer running the program has the .NET framework? I'm just curious, and I think if its possib...

There are a lot of "primitive" boiler plate types of data classes that could appear in many different programs. However, I have never seen a class or library set that recognizes the need to combine all these things with common logic required for them such as validation. Example classes ([] brackets correspond to classes also in hypothe...
Suppose that I am intending to draw some user-supplied text on a bitmap in C#, what sort of tests would I write up front? Is this sort of thing even possible? BDD seems very straight-forward when dealing with mathematical problems but I find it near impossible and more trouble than it's worth when dealing with custom UI controls, graph...

Use an HTTP POST to upload some form data including the username/password. Capture the session somehow. Cookies? Send a series of HTTP GETs to download the pages I need. #3 is easy, I do it all t...

I also want to include a specific ActiveX control in the UI of this app, but the ActiveX control I'm trying to use does not support 32 bit. Is there some trick or work around I can use to use get this control to work? What about embedding the ActiveX c...
Hi, I'm working on a .NET v3.5 winforms app and would like to leverage some support for: a) logging (to file & to perhaps windows events) b) error handling / exception handling framework - to assist in distinguishing messages that can be shown to user versus handled within the code and logged c) a bonus extra would be how to capture/...

When working with Domain Objects, how do you typically unit test a method that calls another method in the object? For example: public class Invoice { public IList<InvoiceLine> InvoiceLines; public string Company; public bool IsDiscounted; public DateTime InvoiceDate; //... public GetTotalAmt(); public GetExtendedTotalAmt...
