Usually when I'm joining a bunch of things to make a string, I'll just do like string a = pt.X.ToString() + ", " + pt.Y.ToString();. I was just wondering if this was considered bad code or something, because any example I see where they are joining things together like this, they use something else besides this. Should I be using something else to join things like this? (Wow that was a lot of "this")
I wish I could drive...

I sometimes just use String.Format(....) ...

Because strings are immutable if there are several concatenations involved it is better to use StringBuilder[^]
For small efforts I might consider String.Format for readability

For a single statement like that, there is no better method.
The compiler turns that statement into:
string a = String.Concat(pt.X.ToString(), ", ", pt.Y.ToString());
This will allocate a string buffer with the correct size and copies the data from each string to it, so it causes a minimum of overhead.
Experience is the sum of all the mistakes you have done.

You should use a string builder

I prefer string.Format for that.
There was a thread on this a few months back.

Calm down. That is not the way to ask for help around here. You might want to look at http://www.connectionstrings.com[^], if I recall, there are connection strings for Access 2007 there...

You also need to be a bit more descriptive about what problem you are having...

Here's the procedure:
- Visit MSDN
- Find the checkbox event to which you need to respond
- Determine the button's property that you need to change
- Write code to do that and stick in the event handler you discovered in step 2

You'll want to set the Enabled property equal to the Checked property. Do this in an event handler for the checkbox when the checked value is changed.

if (chkOptions.Checked == true)
button1.Enable = true;
else
button1.Enable = false;

Hello. FOrgive me for being pushy on the subject of sounds and all, but is there a way to play a wave file that is in your solution explorer, EASILY? Thanks much in advance.

Thanks. I'll check them out now.

No offense to what you already wrote, but isn't there a way to just make a .wav file play that's right in the solution explorer?

Use the SoundPlayer class to play the file.
To access the file, you would write:
Properties.Resources.Wave01.wav
- assuming that the file is called Wave01.wav.

Can you explain that last post some more; I'm still looking into soundplayer.

Create a new instance of SoundPlayer:
System.Media.SoundPlayer MySoundPlayer = new SoundPlayer(); Then tell the SoundPlayer where to find the sound to play - in this case in your project resources:
MySoundPlayer.SoundLocation = Properties.Resources.Wave01.wav; Again, assuming that the wave file is named Wave01.wav.
Now, to play the file, you would do this:
MySoundPlayer.Play(); It's that easy. I recommend you read some more about the SoundPlayer class on the page Ravi posted a link to.

Are you serious!? Thank you so much!!!

But, it's giving me an error. The wave file does go there doesn't it, because that's my error.

It couldn't find it or what?
Make sure the file is added to your project resources.
Go to Project -> [Project name] Properties...
Then click the Resources tab. Click on the little arrow, next to the little button that should say Strings, and select Audio. Then click on arrow right next to the button that says Add Resource, and select Add Existing File..
Then browse to your wave file and add it. Then it should be able to find it.
