Taskbar with FormBorderStyle.None when Maximized [solved]

When we set this.FormBorderStyle = FormBorderStyle.None and maximize the form using this.WindowState = FormWindowState.Maximized then TaskBar get behind the form. I mean the form appears full on the screen. I needed this behaviour earlier but now I want that windows should react like it does with other border style. I can do this by setting Size of form but that doesn't a real maximize. I need realistic maximize, like this.WindowState should return FormWindowState.Maximized. I'm just wondering that is there any way to do that ?

Edited :
Just got it...
this.MaximizedBounds = Screen.PrimaryScreen.WorkingArea;

This should exist on the internet in a much more prevalent location. I can't tell you mow much useless (but educational) code I've written because I passed up this property on winforms.

Because I'm a multimonitor kid, it looks like "this.MaximizedBounds = Screen.FromControl(this).WorkingArea;" to me.

You can specify a format in the ToString method of the numeric type.
i.e. an int:

int number = 2;
string numberString = number.ToString("00");

Let's write a example :
We have a textbox, the user inserts "10010101" into the textbox and we have to send this byte to serial port.

Could you please guide me ?

Your problem might is not related with serial port-it's sample conversion issue.You could convert this string "10010101"
to byte using System.Convert class.

<br />
  byte b=Convert.ToByte("10010101",2)<br />

2 is the base of the number.Now b should be 149 decimal.

Hi,
What is it that you actually want to know?

1) How to use the serial port class,

Your question is incomprehensible. If you're asking how to convert a Delphi project to one of the .NET lanugages, you have to rewrite the project from scratch. There is no conversion tool as far as I know.

Automate processing without button click?

Hi,

I have a winform which checks for emails in outlook and downloads attachment (Excel sheet) and read/display the contents to the user. This is currently done on a button click event. Is it possible to do this task without the user having to click on the button.ie each time a new email arrives the application automatically downloads the attahment , reads/displays the contents to the user?

The button click code is like this

private void button1_Click(object sender, EventArgs e)
{
Class.DownloadAttachment();
Class.Process();
}

Thanks..

It is possible, but is it desirable?
Would you want your work to be continually interrupted? It would become very irritating and would almost certainly result in people not wanting to use your software.

If DownloadAttachment() and Process() are static methods of a class called Class, your choice of 'Class' as a class name is a really, really bad idea.

Lastly you have posted quite a lot of question by now, this is good, don't stop posting, but in nearly all of your threads, that I have seen, you have been asked to put your code snippets in <pre></pre> tags, and you are still not doing so. Please use the tags to make your code more easily read.

Setting an object public property, protected by a security check

Hi,

I have an object that performe a security check before setting a property

Class Issue

string _status
string Status {

set {

if (Value == "urgent" && current.User.IsManager)
_status = "urgent"
else
throw exception

}

get { return _status}

}

The problem arise when I just need to fill the status property from data coming from the Database.
Is there any proper OO way to leave the business logic in the object while allowing at least the db layer to fill this proerty?
At the moment, I have a IssueManager that is responsible to execture CRUD methods on the DB on behalf of Issue.

Thanks

Probably not the correct OO way to do it, we use a bool flag bLoading to short circuit this problem.
