MVVM is most commonly used with WPF because it is perfectly suited for it. But what about Windows Forms? Is there an established and commonly used approach / design pattern like this for Windows Forms too? One that works explicitly well with Windows Forms? Is there a book or an article that describes this well? Maybe MVP or MVC based? ...
I have a datagridview that is linked to a three columns in the database, and it's only displaying them (no editing). When I run the program in debug, and exit, when I return to the form in Visual Studio, it has my three columns, plus all the columns in the table it's linked to. If I don't remove these, the next time I run the program, th...
I've created a custom control (a class that inherits from Control). When I put it on a Form I can work with it on Visual Studio IDE. It shows me an error and I don't see the form. The error message is this: La variable 'ctrlImagen' no está declarada o no se asignó nunca. It's a winform for a Compact Framework app. How can I solve this...

Am I the only one noticing this, or is this really an overall trend? And should all thick-client developers drop everything and begin learning ASP....
Howdy, I am designing a program that dynamically creates its own GUI at run time. I am looking for a firebug like utility that allows me to move my mouse around the form to see different controls highlighted and see what their size, padding, margins, etc are set to. Thank you, Keith ...
I'm using Visual C# 2008 Express. I'd like to use the same icon for the application (ie, the icon shown for the .exe), and for the main form. Unfortunately, VC# doesn't seem to be very smart about this, and insists on duplicating the icon data. There doesn't seem to be a way of selecting an "already embedded" icon for use in the form or...
I'm working on porting a large vb6 application to .NET. The current app is a desktop app that communicates with a set of local access databases.

I want to cache a DataGridView row between 'refreshes' i.e. between a Rows.Clear() and a Columns.Clear().

Hi, I need a open-source/free C# tool or library that can do financial charting for a student project. It needs to be able to do a open-high-low-close chart, and be able to graph various technical indicators that I calculate, all from within a Windows form. Any recommendations? ...

What I want to do, is to force clicking on any link to get this link opened in a new IE window instead of navigating to that page in the control itself. Any idea? ...
