• samymelbourne Inherit Generic Forms

  How can generic forms / controls be inherited I made some generic forms and controls i want to use in my application as base forms/controls. When i inherit these forms/controls i cannot view the designer anymore. Is it possible to inherit these generics and how Nightmare_BE wrote: How do u write the code, when u look at the code of a new form both the form and the designer class are partial classes. Do u put the public class MyCustomIntForm : MyGenericForm < int > { } on top of the form class, at the designer or into a external code file It can't be the first class in the new form's .cs file, because the designer will crack it anyway if you do that.

• TjMulder Form files accidentally split up

  Hi all, I've had this come up a few times, and it seems like it should have an easy fix, but I'm absolutely baffled. So at the risk of sounding stupid, I could use some help! While working in Solution Explorer, I somehow accidentally dragged the .resx and .Designer.cs files of a form out of place, so they're not no longer children of the parent form... they're siblings in the project folder. My code compiles fine, but when I try viewing the form in Designer mode, the form shows up blank. Plus, the misplaced files add clutter to my project directory. I can't for the life of me figure out how to move these files back into place as children of the form.cs file. Does that make sense Anyone know a solution Thanks! Mark Jacobsen ...Show All

  When attempting to reply to or send an Outlook message when accessing my employers Web VPN service on my home computer I receive the following message: "one or more errors occurred while the message was being sent.

• Manivannan.D.Sekaran VS 2003, develop Web Services "offline"

  With Visual Studio 2003 (any language, but we happen to use C#), it seems you can't develop Web applications in the IDE without connecting up to a web server. In other words, I can't just copy the files to an offline folder (meaning, some folder that isn't part of a web server virtual directory), double click on the .csproj file, and be off and running. No... I must tell it where my web server is. What if I don't have access to one at the moment. Sure, I'll need one to test and debug, but I need one to start writing the code This doesn't just go for web services, but seemingly any web based project. Thanks... I also have access to VS 2005 and I've experienced everything you have said. Was just hopi ...Show All

• Duncan-Countrywide casting

• Jim Altrichter Properties in C#

  Hi All, I really have a doubt regarding use of property in C#. My question is: Can we have private properties inside a class If yes, then please let me know what is the use of private propertise in a class. Thanks and Regards, ChatanyA Agrawal By using a Property you dont need to create two different methods to set a value and another to retrieve a value. In a single property, with the same name you can get and set. Although this can also be achieved through an overloaded method. You have a very good question as to Why use private properties. Consider this: private int Kilogms { set { grams= 1000*value; kilogms = value; } get { return kilogms; } } ...Show All
