It's one of those things I see a lot but never really think of. Do you think for the purpose of web application development (specifically ASP.NET WebForms/MVC). Do you think it's advantageous to do such a thing and if so, what kind of advantages come out of it? By virtualization I mean using products like Hyper-V to separate the serve...

Having a weird problem here. Everybody knows that if you use web.config's customErrors section to make a custom error page, that you should set your Response.StatusCode to whatever is appropriate. For example, if I make a custom 404 page and name it 404.aspx, I could put <% Response.StatusCode = 404 %> in the contents in order to make it...
im not sure if there is a difference in these two methods. If so, which would be considered the better practice when submitting more than one object to the View. 1- Having the controller make separate calls to the datalayer for each object model and then wrapping the objects in a model to send to view. 2- Defining a "presentation" mode...

One of our clients is breaking the software in every way imaginable, and he's just discovered this one. If the user tries to upload a file with a very long filename (I think the user is trying with a 180 character filename), the FileUpload control refuses to recognise it on IE7. Click on the Browse button, browse to the file, click on ...

Variable number of pages with frames, tables, logos and headers/footers. Today I use custom forms and CSS for certain things and iTextSharp for others (I work with asp.net and MS-...
