Re: Looking for a better way to build a Dataset

Just load it into the XML , it is very simple. and you have lots of methods to write , save ...xml using datasets

Like the other's suggested I would use XML also. In your case you are interested in the DataSet.ReadXml() and DataSet.WriteXml() methods. I would:

1) Input all the data by hand into my DataTable and then add that DataTable into a DataSet.

2) Call the DataSet's WriteXml() methods and pass a FileStream into it so you will end up with a file.

3) Now you can use that file as a template to manually change the Value tags in there.

4) When you are done with changing your Value tags you can call the DataSet's ReadXml() method, with another FileStream, to take all your data in the XML file and put it inside a DataTable and a DataSet.

Sending contents of a text file via emails

I am trying to find a way to extract and send the contents of TEXT FILE 1, via email, to a list of email addresses in TEXT FILE 2.

So just to clarify, I would like some code which will rip the contents of Text File 1 and send the contents to everyone in Text File 2.

Any help received will be greatly appreciated.

Thanks,

You should just lookup the System.IO class for reading files. I think there is another class that works on top of a System.IO.Filestream or FileInfo or something. It reads text into strings.

As for the email, check out System.Web.Mail;
You are going to want something like:

SmtpMail.SmtpServer = theIP;

mailMsg = new MailMessage();
mailMsg.From = "stuff@stuff.com";
mailMsg.To = "recipient@anemail.com";
mailMsg.Subject = subject;
mailMsg.Body = body;
SmtpMail.Send(mailMsg );

Are confused about how you could actually traverse through the files in the text files?

Hope this helps,
Jim

Your spelling and phrasing makes it difficult for me to understand what you're asking. Do you want to print your form, and only your form? Or are you trying to print your form, and anything that's on top of the form (like the task manager)?

Adding custom buttons to MessageBox

2-Mar-05 4:04

Please see this recent MSDN article, in particular, scroll down 3/4ths of the way down the page and you'll see the exact problem you're describing:

Process::Start("http://www.microsoft.com");

Alas, if you try this at home, the same thing happens. The call throws a Win32Exception which yields an even more cryptic code in its NativeErrorCode property: ERROR_SXS_KEY_NOT_FOUND. The description for this error is "The requested lookup key was not found in any active activation context." Huh?

If you poke around the documentation for Process and read all the fine print, you'll discover that Process uses something called StartInfo in order to tell it how to start the process. One of the properties in StartInfo is UseShellExecute. By default, UseShellExecute equals True, which tells the Framework to launch the process using the shell, that is, ShellExecuteEx. Okay, so try setting it to False. But then, as the fine print explains, you can only start EXEs, not file names or URLs.

The article mentions some other options, such as using rundll32, to launch your URL.

Hi,

Is there anyway to add a custom button using the .NET MessageBox rather than creating my own class to do this? I wish to add an Extra Info button to a message box and hook in an event handler e.g. be able to:
MessageBox.Show("Error", "Error", MessageBoxButton.OK + MessageBoxButton.ExtraInfo);

Many thanks,
Gary

Re: Adding custom buttons to MessageBox

2-Mar-05 4:16

I don't think so. There are some other existing message boxes built into Win32 that you could wrap (for example, SHMessageBoxCheck), but if you're trying to do anything elaborate (for instance, display a checklist of files to be saved), you'd be better off implementing your own MessageBox.

You might be able to do something with an article on MSDN, written by Dino Esposito (Windows and .NET GOD! IMHO), Using Windows Hooks to Enhance MessageBox in .NET[^]. I don't if any of the techniques will let you do want to you want, but it's worth a look.

an install wizard application

I used the wizard to create an install application. I works fine except if a file exist it does not replace it.

If "C:\mydir\myfile" exist then it does not install a newer version.

Is there a property I can set to say, replace existing objects?

thanks
