Then you will have to list a very good reason. System.Net.Mail.SmtpClient seems aptly suited. You could use System.Net.TcpClient instead but it would be more tedious. BTW, mailto:, does not work according to your specs at it requires outlook to be installed and configured. (or another email client)

System.Net.Mail.SmtpClient would require my application to store UserID, Password, Server, Port, etc. to send an email using an SMTP server. Additionally, this would bypass their mail client and I would be responsible for keeping sent messages, etc. I was trying to avoid building an email client into my application and the complexities of configuring that for the end user. That is the very good reason.
I am trying to leverage the existing client and configuration that most likely already exists. mailto is working fine as described (as long as they have an email client installed). I am trying to figure out how to extend that functionality and attach a file to the opened email message window programmatically.
As mentioned, similar to Winzip "Compress and email". They may be using Outlook automation to do that. Anyone using Winzip something other than outlook or outlook express for an email client? If so, let me know if Winzip still provides that option and how it works.
Thanks.

May be available through a windows interface. You can most definately get the email settings from outlook. For Thunderbird, I dunno. One option with the mailto: would be sending the attachment in the body using UUEncoding however I imagine the console has a character limit.

I am new to C# and have a class project to work on. I am trying to create an Amortization calulator the display the payment results based on the Time period thay have to repay the loan. The calculation part of it is working fine but I can not get it to display the result. Can I please get some help with this? See code Below:
<script runat="server">
protected void Button1_Click(object sender, EventArgs e)
{
Label6.Text = "Final Balance: " +
CalculateBalance(Convert.ToInt32(TextBox1.Text),
(Convert.ToDouble(TextBox2.Text) / 100),
Convert.ToInt32(TextBox3.Text),
Convert.ToInt16(DropDownList1.SelectedItem.Value)).ToString();
}
private string CalculateBalance(int Principal, double Rate, int Years, int Period)
{
double result;
double NumToBeRaised = (1 + Rate / Period);
result=Principal * System.Math.Pow(NumToBeRaised, (Years * Period));
return (result.ToString("C"));
}
private string AmortDisplay(double Principal, double results, int Years, int Period)
{
int AmortTime;
double AmortPayment;
double RemBalance;
string Output;
AmortTime = (Years * Period);
AmortPayment = (results / AmortTime);
RemBalance = -(Principal - AmortPayment);
TextBox4.Text = "Duration\t \tPayment\t \tRemaining Balance \n" + AmortTime + "\t\t" + Convert.ToString(AmortPayment) + "\t\t" + Convert.ToString(RemBalance) + "\n";
}
protected void Button2_Click(object sender, EventArgs e)
{
AmortDisplay(Convert.ToDouble(TextBox1.Text),
Convert.ToDouble(Label6.Text),
Convert.ToInt32(TextBox3.Text),
Convert.ToInt16(DropDownList1.SelectedItem.Value)).ToString();
}
</script>

Someone might help you, especially if you post a question or problem instead of just saying "I can not get it to display the result."

this is a re-post. I would suggest that you read 'how to get an answer to your question' at the top of the forum. I am sure that someone could answer a question for you if you ventured to actually ask a question, provide some detail, etc...

The code you posted will not compile. The function AmortDisplay, as written, does not return a value but is declared as returning a string.
In the calculation of Textbox4.text, AmortTime is not converted to a string.
This would be better done using String.Format anyway.
There is no error handling (try...catch) to capture conversion errors,
so any exception will just propagate up to the top and crash...
Why do you convert the result of CalculateBalance nto a string
(as the return value) and then immediatly convert it back
to a double in order to pass it to AmmortDisplay?
Clean up your code. avoid conversion operations in the parameters passed
to a function (do these as separate steps with local values,
pass the local values) - this:
AmortDisplay(Convert.ToDouble(TextBox1.Text),
Convert.ToDouble(Label6.Text),
Convert.ToInt32(TextBox3.Text),
Convert.ToInt16(DropDownList1.SelectedItem.Value)).ToString();
will be very hard to debug, and there are at least 5 opportunities
for a mistyped (or empty) entry field to cause an exception to be thrown
in that single function call.
Why the .ToString() at the end? the function called should have returned a string
(and would have, but you left out the return statement) anyway..
You definately need to study harder. This is really poor code, and would be unacceptable
in any production work.
Some advice:
1. Keep it simple, avoid complex function calls with nested calls
2. do things in clear descrete steps so you can inspect each easily.
3. don't change data types any earlier than necessary.
4. inspect your code with the presumption that there is a stupid error or oversight,
the best of us still make these occaisionally.

Hello,
I have 2 treeView controls on my form. Can you please tell me how can I copy all the nodes with the same structure from treeView1 to treeView2?
Note: I'm using .NET 2005.
Your help would be greatly appreciated.

|
|
|
|
treeView2.Nodes.Clear();
foreach(TreeNode node in treeView1.Nodes){
treeView2.Nodes.Add(node);
}

Thanks but I got:
Cannot add or insert the item 'Dogs & Cats' in more than one place. You must first remove it from its current location or clone it.
Parameter name: node

I'm gonna take a stab in the dark and suggest TreeNode.Clone().
foreach (TreeNode tn in treeView1.Nodes) {
treeView2.Nodes.Add(tn.Clone() as TreeNode);
}

Hi, Does anybody know how to make a TextBox Array in a C#.NET Web Application?
And for CheckBoxes?
Oren,

TextBox[] tb = new TextBox[3];
CheckBox[] cb = new CheckBox[3];

now i want to set the form color to this.
this.color=clr;
how to assign values to color variables?

Color is a struct and therefore mutable, supply values to it's static FromArgb method instead of trying to set properties after initialization.
Color c = Color.FromArgb(r, g, b);

as it is more suited to saving in a database.

You're correct in this case (if you prepend "im" to the word "mutable"), but structs in general are not necessarily immutable. Immutability of structs is a best practice, not a rule.

Woops! My intellisence ain't working today. Thanks for catching that.
And my understanding was that all structs are immutable, trying to change them just creates and swaps a new one behind the scenes, like strings or any other stacked value. So they seem to be mutable, though technically they are not. Maybe I have it wrong...

Structs (aka 'value types') are copied by reference, but that doesn't imply immutability.
This code creates a Point struct and modifies it (not a copy of it):
Point pt = new Point(1,1);
pt.X = 2;

Can you group together CheckBoxes so only one in a group is checked at one time and if so How?
|
|
|
|
|
Winforms or ASP.NET?
If Winforms:
Use RadioButtons instead of CheckBoxs. Put them in a GroupBox or Panel and they'll automatically be mutually exclusive.

Winforms, and i can't use Radion buttons because i am looking for the sticky button look that a check box has.
