Can anyone see where I am going wrong ? It just comes up with an error, fail to send.

~Thanks~

DAMN that's 2 days i've been stuck on that !!

CurrentFontSize = Me.RichTextBox1.SelectionFont.Size

RichTextBox1.SelectionFont = NewFont("Comic Sans MS", CurrentFontSize, FontStyle.Bold)

Can u help with this, is there a way just to underline or strikeout text without havin the declare a new font ?

Gregor.

privatevoid button1_Click(object sender, EventArgs e)

  {

    n = rnd1.Next();

    this.label1.Text = n.ToString;

  }

Can you recommend a good book for C# ?

Just one more question, I think if you call the datetime value you get a format like 11/12/2009, is it just a case of parseing out the "/" to make up the file name I want to use it as ?

Thanks

As for your code, the Value property of the DateTimePicker is already a DateTime type (similar to VB's Date type). Just call ToString() on the Value property and you'll get the default string representation of the date.

What does "master of baiters" mean

For error handling, you're meant to use Try/Catch and Exceptions; The "On Error Do Something" in VB.NET is meant as a crutch for backwards compatibility with VB6 (i.e. never use it in new projects).

 

To see if a file exists or not:

 

try {

    FileStream fs = new FileStream("path to file");

} catch(FileNotFoundException fex) {

}

 

...of course, you should never use exceptions for normal program flow, it's much better to test first:

 

try {

    if( File.Exists("path to file") ) {

        // do file operation here

    } else {

        // show error message to user

    }

} catch(IOException ex) {

}

 

And as you're using C#, you might as well make use of the using() {} block to ensure your program doesn't shít itself if something bad happens in the file IO ops.

Thanks

Converting to string, substringing and parsing to integers is not really nice. And the DateTime-constructor you use is used wrongly: the first argument is the year and not the day.

Long live integer division and modulo:

int d = 25122009;
DateTime date =
  new DateTime(
    d / 1000000,
    (d / 10000) % 100,
    d % 10000);

Why can the first argument not be the day ?

An "int" date?

 

If you've got a DateTime instance, just call myDate.ToString(); you can optionally specify a format-string or predefined culture settings to get the right format (e.g. myDate.ToString("yyyy-MM-dd"); or myDate.ToString(CultureInfo.CurrentCulture); )

 

In .NET, every class inherits Object's .ToString() method, by default this method simply returns some basic information gained from Reflection, but some types (such as DateTime) override the behaviour. There is also the System.Convert class, but I find myself rarely using it (since it's nothing you can't do with the existing .TryParse / .Parse / .ToString methods.

I got it you need () at the end of tostring !

C# is new to me. Why does it not do the () in the dot completion system ?

I got another question... In VB I use On Error Resume Next for errors, I need to write files and at times a file does not exist so i use the Error Handling to keep the code running. But I don't know how to do this in C# ???

Thanks for help.

I'm no good at this, this is my code.

there is an error on the line, [string mydate..... ]and the next one ????????

int thedate = this.dateTimePicker1.Value.Day & this.dateTimePicker1.Value.Month & this.dateTimePicker1.Value.Year;

string mydate = thedate.ToString;

this.richTextBox1.SaveFile(mydate);
