You could box the output in an object;
object GetValue(bool test)
{
if (test)
return 1;
else
return "2";
}
The factory-pattern[^] might also be interesting

Does anyone know how to make a .NET app so that the files it generates cause previews of the file to show up in Windows Explorer instead of static icons? Even simply telling me what that concept is called would be helpful as the searches I'm trying aren't working. Thank you!

It's called Preview Handler[^] but it is not recommended to develop them in .Net

Thank you! The article you linked to appears to be related to the preview pane. I'm wondering how to create an add-in that causes a little preview to appear instead of the icon itself using traditional techniques that will also work in XP. I've seen some other apps do this so I know it's possible.
Coding it in C++ won't be an issue.

Hi everyone,
I would like start a 'simple' 3D project in C# and wonder how to start with.
Background:
The project is an application for my bicycle ergometer connected to my PC. I would like to display a cyclist in a 3D landscape, which, of course, moves depending on speed/rpm.
At first there is noch need in any landscape details, just a track with curves and a cyclist.
Questions:
1) Should I use XNA or Direct 3D or something else ?
2) Is there any sample (a race simulation or so) which I can use to start with ?
3) What are your experiences when you started programming 3D ? Is it necessary to go through dedicated tutorials or is there any chance to take come sample code to work with quickly ?
Regards

XNA is a fine environment to start with. You might want to take a look at this[^] site to get some help with it.

But not to us.
Tell us what you have tried, and what does not work, and maybe we will be able to assist. But we are not here to do your work for you.

Did you ever searched google before asking this question ? Sending mail is one of the common things in .NET and if you know the basic of web service you can implement it.
1. You need to create an web service
2. Create method as SendMail(), which may accept From, To, MessageBody information as argument.
3. Host the Web Service.
4. Consume from Client
For your Reference :
A .NET web service for e-mail[^]

{ adapter.SelectCommand.CommandText = sql;

Look into DataAdapter.Update , but it has limitations.
I avoid DataAdapters altogether.

You should use the .NET Printdocument Class[^].

You really do not like this person do you, Crystal Reports is one of the greatest PITA on the market today, recommending this poor person, who is obviously a newbie, to use CR is a great disservice to him/her. There are many, better options than CR for report processing.

No you don't. There are better options, like SSRS, Active Reports, etc. Besides, the OP just wants to print the document, not create a report.

I have completed a simple windows project and wish to deploy it. I wish to create a proper installer like those that appear in professional applications. I don't wish to use the publish option form project properties as it just creates an executable. I also tried the Setup and Deployment project in other project type but got confused and messed up.

right click on solution-add new project-Expand other project type-Select setup and deployment...
try this way.

You waited over six hours for this. A google search with decent keywords would have yielded a similar result in less than six seconds.
