A datagrid ? You mean so that you have a layout where some rows have different size columns ? You can't.

Hi I have for quite some time used the below code to check if a computer was connected to the internet for my apps, but recently found out that that solution came short in companies using proxy servers. Is there any who know how to implement that in the below code?
Basically I thought of trying to get the proxy settings from the default browser or like. But what is "normal" standard? and do any have an easy solution to this below here.
public static bool CheckInternet()
{
try
{
System.Net.IPHostEntry objIPHE = System.Net.Dns.GetHostEntry("www.google.com");
return true;
}
catch
{
return false; // host not reachable.
}
}

Hi,
I am using a DataGridView and i want it to be always expanded to the whole control. I've set it as fill, but it never fills the whole screen like the error list in vs2005. Is there a property or do i need to manually work out the size and set it that way?
Regards,
Gareth.

hi,
I believe its a form that u have put your grid on. Now, when you go to the properties window of the grid, locate Dock property of the grid and set it to Fill,i.e., select the big central square shown in the dropdown list.
the result of this change is instantly updated on the form and now u wud be able to see the grid stretched to the entirety of the form, now at runtime, even if u resize the form, the grid would be always auto-resized to cover up the entire form.
|
|
|
|
|
moreover, if u want to stretch the grid to the whole screen, then set the FormBorderStyle of the form to None and WindowState to maximised alongwith the Fill of the dock property of grid. but be careful to provide an exit point on the form or grid somewhere, otherwise, u wud really be annoyed if u see the entire screen covered up by the silly grid and u r unable to access any other program.

Hi gladiatron,
I don't use a form, its in a panel. And when i said i had set "it to fill", i meant i had docked it already.

I have few checkboxes in my form, and i want to get only those which are checked. Can this be done only in 1 line of code? As i know the loop to execute and get the checked values.
Thanks in advance for your help.

What's a line of code?
If you encapsulate the details in a method you need only use that method.
|
|
|
|
|
What i mean to say, is it possible to do it without a loop only with 1 line of code ?
|
|
|
|
|
Only if the line is really long, or calls a method that does a loop.

Perhaps.

Perhaps not.
How about adding a collection for the checked CheckBoxes to your form, and having the CheckedChanged event handler(s) add and remove them as appropriate?

Probably only if you use a loop or as a procedure like CheckForCheckedCheckBoxes();. What is it that you want to do with the checked checkboxes when you find them?

Add an event to the CheckChanged event. In that code you can use code to populate a list. The one line of code would be:
someMemberList.Add((CheckBox)sender);
In the event.
The easiest method, however, is just the if statements. You mentioned a loop so maybe this is ASP.NET so there is a complicated simple way to do it by getting the submitted value by the id of the check box so long as every check box has the same id.

What about repeated clicks? Check - uncheck - check

|

object o = ((Checkbox)sender).Checked ? list.Remove((CheckBox)sender) : list.Add((CheckBox)sender);
Just might work, or some variation thereof There is always a way to write bad code. Use a hash to avoid duplicates if it really matters.

I have been reading up a lot on the different standard file wipe algorithms that exists and I was hoping that someone could explain one thing to me.
Most of the algorithms are straightforward and shouldn't post to much difficulty to implement but I don't understand the verification part of some of them.
Take the standard DoD 5220.22-M for example which states:
- US Department of Defense DoD 5220.22-M (3 passes)
DoD 5220.22-M is three pass overwriting algorithm:
first pass - with zeroes, second pass - with ones and the last pass with random bytes.
With all passes verification.
or the US Army AR380-19:
- US Army AR380-19 (3 passes)
AR380-19 is data wiping scheme specified and published by the U.S. Army.
AR380-19 is three pass overwriting algorithm:
first pass - with random bytes, second and third passes with certain bytes and with its
compliment (with last pass verification).
The three passes is not a problem but what am I suppose to verify?
|
|
|
|
|
Maybe verify it's not the original data?
|
|
|
|
|
That's what I was thinking, but that doesn't seem very realistic.
Imaging if I wanted to erase a 4 GB DVD-ISO, that would mean I have to create a 4 GB byte-array before the first pass and compare each byte later.
|
|
|
|
|
Unless you things byte by byte as you go.
|
|
|
|
|
So if the random byte you want to write matches the existing byte, select a different random byte? Oh there's a good use for clock cycles.
|
|
|
|
|
Meh, they never said anything about that!
|
|
|
|
|
They must have forgotten to. What if your random bytes just happen to all match the bytes to be wiped?
