I've found this topic not well documented.. actually, I was playing with Custom Configuration Handlers, but it's related.
Ok, to the point  , every time you compile your program using Visual Studio .NET it will look for a file named app.config, if the file exists, it will create an output file on your destination directory (Release or debug for example) with the following name:
<ApplicationName>.exe.config
This file will contain the data you put on app.config.
Be aware that this file will be recreated everytime you compile your program (this got me for a while), so if you change the output config file, the changes will be lost on your next recompile.
If you need to change the config file during development, change app.config, you are going to see these changes reflected on your output file.
Hope this helps.

Ok, I know this must be a really dumb question, but how do I add an image to my project in Visual Studio.NET so that I can reference it in code such as "myPicture.jpg". Thanks again, don't laugh too much

So such thing as a dumb question
Right click on the project and choose Add Existing Item, select your jpg. Click on it in Solution Explorer then in the properties box change the Build Type from Content to Embedded Resource.
Now when you want to load it,
Bitmap myJPG = new Bitmap(GetType(), "myPicture.jpg"); assuming that the class is in the same assembly (ie project) as the jpg.
Good Luck,
James

Thanks James, sometimes some of the easiest things aren't known by all, I just hope this helps someone else too.

I wouldn't classify it as the easiest thing to come up with; it took me about a day of working on my own to figure it out. And then I read it last week in Petzold's book

Are you sure ? :P
This question was one that got me though, and I still don't think I fully have a handle on how to make it work. It just happens to work in the project I am working on, so I don't mess with it. Actually, I think someone else fixed it for me...

No, I'm never sure of myself; to become sure makes me ignorant of other possibilities. I am confident in my answers though but I leave myself open to other solutions

I think when we've got the screensaver pretty hammered out I'll write an article on using resources. Then I need to write part two to Nish's Registry article

I'd considered trying to hammer out a decent registry class. I still have my bottleneck detector code waiting for an article, as well. I'd like to get a decent article up on the screensaver as well, sometime soonish.
I'd love to read an article on using resources, I couldn't get that thing you did to put them into a subfolder to work at *all*.

James, if I wanted to draw this image in a random location on the screen after I create my graphics object Graphics grfx;, what method do you suggest, there are 30 of them with just the .DrawImage() method(s).

If you just want to Draw it without modifications, use DrawImageUnscaled; each of the other variations of DrawImage let you do slightly different things, about half of them doing the same but taking RectangleF/PointF instead of Rectangle/Point.

C++ allows to use default values for parameters e.g.
void MyFun(int nParam1, nDefault = 0);
Is it possible in C#? If yes, how to do it?
|
|
|
|
|
void MyFun(int nParam1)
{
MyFun(nParam1, 0);
}
void MyFun(int nParam1, int nDefault)
{
}
In other words, No...

Default parameters are not inherently supported in C#. You need to define an overloaded version of the method that doesn't require the parameter (that defaults it) and call the version that contains all the parameters. Before you say it, I agree that it sucks

How could they leave out something so trivial to impliment, and so useful ? Templates I can understand given that Microsoft are yet to release a worthwhile implimentation of templates on any platform, but this just blows.

we've had many talks with Eric Gunnerson about this on the aspfriends.com email lists.
you may disagree with it...
but the reason they didn't implement it was because they favored ( by a small margin ) overall simplicity against More Features©
however, we have been fairly successfull at giving good arguments for it... and they are still considering it for v2.

The more I use C#, the more it treats me like an idiot. It's clear to me they went for simplicity, for the benefit of people coming over from VB, I suspect.
Thanks for the insight.

This is actually not the case. According to the C# Product Manager it had more to do with versioning than anything.

It's a percieved issue with distributed libraries ? Given that people are talking about doing the same thing via two functions, the hard coded values are still there, we're just finding ways around the limitation in C#.
But of course, I should be telling Joe this
Thanks for the info. BTW, Amazon shipping my copy of Inside C# on the weekend, so the delay was not that bad. Soon I will actually start learning me some C# instead of flailing around blindly. The Petzold book is helpful when I have a UI issue, but the other book I have, I have quickly outgrown.

Agreed. There were many situations where the reason for omitting something from C# that most C++ developers would consider important was due to versioning

Here is what Eric Gunnerson had to say about the subject on the aspngcs list.
[The discussion was regarding optional parameters in VB, but they are essentially the same thing]
I'd like to try to share a bit of the language designer perspective to this.
When we look at features, the question that we try to answer is:
Is the utility that this feature adds worth the additional complexity in the language?
When we did this for C#, there were a number of cases where the tradeoff isn't clear-cut. Our default decision is not to add a feature, because simplicity is also a feature. To put this another way, C# is already more complex than we'd like it to be, so additional features have to be really useful to meet the cut.
Then later,
I appreciate the feedback. I'm not sure you have to persuade me - I'm pretty much on the fence on this one. You'd really have to persuade Anders...
I can give you a bit more perspective on this issue.
In C++, default parameters don't version well, because the default value ends up in the client code rather than your library. I think that's a pretty serious drawback, and I don't think it's the right approach for C#.
One other thing we've considered doing was having the compiler take a definition like:
public void (string s1, string s2 = null, string s3 = null)
{
}
and generate the other two overloads.
IIRC, we're planning on discussing this so more, but I don't know what the outcome will be.
If anyone wants I can e-mail them the thread (titled "Optional Parameters in C#" for those on the list).
