You could use a regular expression to do the pattern matching.

What is the easiest way to save a database password in my xml settings file? I'm currently writing all my db connection settings to an xml file. How can I write out the password so that people cannot read it?
Thanks

I guess you need to come up with some sort of encryption ( or better yet, find one in the system.cryptography namespace ) and use it to hide the password.
|

You can use one of the crypting alorithms under the System.Security.Cryptography namespace. These algorithms will quite help you. And there are a lot of info about these algorithms on the net if you are interested in. My favourite one is the Rijndael algorithm.
On the other hand you can make your own algorithm  . Like when writing the passwords to the xml file -if the passwords you are protecting are not as important- simply taking the complement of all characters, and when reading back again taking the complement of all characters. This is not the way to stop crackers but at least it is a way  .
Good luck.

i'd be tempted to use a hash in this situation rather than a 2-way encrypt
this article's got loads of info on hashing / salts and challenge response systems

i guess it depends on how secure you want these things to be

code :
OpenFileDialog dlg = new OpenFileDialog();
dlg.Title = "Open text file";
dlg.InitialDirectory = @"c:\";
dlg.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
if (dlg.ShowDialog() == DialogResult.OK)
{
StreamReader sr = File.OpenText(dlg.FileName);
string s = sr.ReadLine();
StringBuilder sb = new StringBuilder();
while (s != null)
{
sb.Append(s);
s = sr.ReadLine();
}
sr.Close();
this.richTextBox1.Text = sb.ToString();
}

Look at the System.IO.File[^] static class and the System.IO.FileStream[^] class.
Also, search the web for articles on how to do this; there are hundreds of tutorials and examples on how to do this.

Hi, I want to test my little text editor app on another computer but when I have sent things like this to friends over msn, they get an error, is there someway of bundling the framework with the program or is the only way to turn it into an installation type thing with the framework with it?
Thanks.

They can just download and install the framework. No, there's no way around it.

Hey Chris,
That's not 100% accurate
take a look at:

I know there are products which allow you to create a free standing exe, but pointing that out just muddies the waters. None of the solutions I know of are cheap, and really, I think they are a bad idea in any case.

Bundle your app with the .NET framework. Alternately, use the bootstrapper built-in to VS to generate a setup program that downloads and installs the .NET framework only if required.

he he he I'm sorry, when I was looking for "Vertical ProgressBar" I'd write "Vertical ProgresssBar". Sorry.
I'd need the vertical progressbar because my form it's little limited of space, but I find space.
Anyway thanks.
SINCERELY.

Hi,
I have an unmanged exe and I would somehow, like to have it run inside my form. I don't care how, but is it possible?
I just want my app to be a container, or to contain the other unmanaged app.
Any ideas?

You can probably hack this together by making your unmanaged app a child window in your managed app. I would not do this for production code ,tho.

Is there input data from the device when a non-magnetic card is swiped? If not then No.
