If you just want a light-weight method to play WAV files, then use the System.Media.SoundPlayer class. Otherwise, just embed a Windows Media Player control into your form

How about using Windows media player? Nobody here is going top "send" you a program. Maybe you can try www.rentacoder.com to write you a program and you can pay them a fee for doing that.

Perhaps you should've said 'my sig' instead. When i read this at first I thought you'd gave the answer in a previous code begging thread he made.

Help on Dialog

Hi everyone.
I'm given a project on C# to develop an advanced font dialog. Instead of the normal
window font dialog, im suppose to customized it by adding few more function by adding a text box to allow user to type in to test the font,
a code page to see the list of character, and the unicode subrange. Its just like integrating the window character map into the font dialog.

I know i have 2 approach to do this.
1. by calling up the original font dialog and start editing the form.
2. Create a new font dialog

Im targeting no 1 since to create a new one, i would have to link them up all together and have to find a way to get the fonts list in the computer.

Anyway, the big problem i have with choice no. 1 is:
1. I dunno how to call up the Fontdialog
2. Im not sure how to expand the font size to allow more info to be display there.
3. Lastly and i don't know how to call up the code page, unicode or even create a textbox that is linked with the "fontstyle", "font", "size" and etc.

I just hope anyone here can advice on the approach to do or give me a link that might help. Am not that good in C# but this project
is hand picked to me, so i have no choice. I spent the whole day trying to solve and search on google to no avail.

Any input will be helpful.

Thx for reading guys. Frown | :(

Number 2 will probably be easier
something like

System.Drawing.FontFamily [] families = new System.Drawing.Text.InstalledFontCollection().Families;

Google a bit, probably easier then you think.

Hi,

I would start out with my own dialog and enjoy my freedom, rather than fighting the limitations of the existing dialog. And I would use the InstalledFontCollection class to get started.

I also think you should go for option 2, it will be cleaner and easier to maintain and as a plus you could put it up as an article here.

You should be able to get the list of available fonts like ElliotA showed you, and you can use the fonts in that list to set the font on a text box (Just a matter of copying all the properties in the Font object you have, to the Font property of the text box)

Remember, if you come across any problems that you can't find answers for, or there is something you don't understand you can always post another question.

Hang on...Let me get this straight. You want to "develop an advanced font dialog" by extending the existing one, but you don't know how to even open the existing one, extend it or even create a text box with the font name in it. Oh, wait, and you're "not that good in C#".

My advice is that this is not a project for people who are "not that good at C#". My advice is that you go back to your manager and tell him that you can't do this and see if you can get him to assign you a simpler project to begin with. You have to start with the simple things and build up to the complex stuff.

You can read about the FontDialog class here[^]

The FontDialog class calls into windows API's to display the inbuilt common dialog. You cannot directly subclass this from .net. Your best bet would be to write one from scratch, or find a pre built one available on-line.

I wish i could do as you said, get a new project to do.
However, this is my school project and the school pick everything
for me. I don't get a choice. Whats worse, my supervisor is not
even helping at all by sleeping at the back of the class.

Anyway, thx for the reply. I go by the advice and create a font dialog of my own. Also able to retrieve the system font.
Now the problem is i don't know how to apply the effects (font, style, sizes, script) to the sample box for the user to see the changes.
Any help?

Also i've search through google, and i just can't seem to find ways to retrieve or create the character set, character map or even the unicode.

Sorry, I don't have any sample code for adding UPS shipping to your webpage.

Don't UPS have documentation for their API? It seems like it is a bit of niche thing to need.

I want to encrypt/decrypt some data with RSA. I have the private key (D and Modulus) and the public key (Exponent and Modulus) saved in text files.
When I tried to decrypt (encrypt data with private key) I tried to import RsaParameters with D and Modulus set to the values in the file and the other parameters set to null. On the Import method it throws a "Bad Data" Exception. It seems that I can only import RsaParameters when all of the parameters are set? Can I do it any other way?

Bad Data exception can occurs when your key is wrong. Your private key and modulus are binary data, perhaps they have been ASCII armoured in the text file?

I think that the error you are getting might be related to the length of the data you are trying to encrypt.

RSA was designed for encrypting/decrypting cryptographic keys, not data. I cannot remember off the top of my head the max length, but if you plough through the MSDN Documentation, it is in there somewhere.

As I said at the start this is only a MIGHT BE, but given that RSA has this length problem you would be better off switching to another encryption provider now, rather than wait till it breaks before doing so.

No, the exception is thrown on the Import()-method, while importing the keys. I checked the keys also, they're all correct...
In fact this gives the error:

<br />
            RSACryptoServiceProvider provider1 = new RSACryptoServiceProvider();<br />
            RSAParameters p1 = provider1.ExportParameters(true);<br />
<br />
            RSAParameters p2 = new RSAParameters();<br />
            p2.D = p1.D;<br />
            p2.Modulus = p1.Modulus;<br />
<br />
            RSACryptoServiceProvider provider2 = new RSACryptoServiceProvider();<br />
            provider2.ImportParameters(p2);<br />

The only thing that strikes me as, possibly, odd about your code is the creation of p2. Why not simply re-use p1?

RSACryptoServiceProvider provider1 = new RSACryptoServiceProvider();
RSAParameters p1 = provider1.ExportParameters(true);

RSACryptoServiceProvider provider2 = new RSACryptoServiceProvider();
provider2.ImportParameters(p1);

Re: C# RSA

Because all the parameters of p1 are set, and i want to simulate a situation where there are only the D and Modulus parameters set...
