) No, not a hacker. I'm IT manager in a company with 270 workstation and I need to solve the licenses problem, being a mess. I want to make a database with hardware components, obtained through WMI (done) and licenses.

Thanks to all of you.

System.Management is undeclared

I wanted to try out using System.Management
but the compiler (I tried sharp-developer and Borland
c# builder) says that System.Management is undeclared.

What do I have to do, to make System.Management known?

Other namespaces, like System.IO, System.Net are available,
and I could compile and run programs using them.

I installed .NET 1.1 completely from the archive that
is about 100MB in size / os is Windows XP.
I found on the web, that XP should have WMI installed already.

Thanks !!

well to call a base class as in java

Form1
super("My first form");

would be in c#

From1
base("my form"); // or whetever arguments are expected

if its a contructor

public Form1 () : base ("")
{}

if (!System.IO.Directory.Exists(FolderPath))
System.IO.Directory.CreateDirectory(FolderPath);

FolderPath is a string containing the full path of the folder in question, like @"C:\ThisFolder".

Hope that helps... Smile | :)

How can I capture all inbound and outbound traffic from a computer? I remember seeing a few projects such as MyDUMeter(http://www.codetools.com/useritems/MyDUMeter.asp), but I would like to block certain packets being sent or received on various ports.

Any help would be greatly appreciatedly thank you. Smile | :)

Centering a form?!?

30-Jul-03 11:36

I must be going mental or something because I can't for the life of me get one form to center on top of another. It seems to me that this code should work, but it doesn't.

this.Top = (this.Owner.Height / 2) - this.Height;  // I've tried both + and -
this.Left = (this.Owner.Width / 2) + this.Width;

but it never centers the form. What am I doing wrong here?

Your formula is wrong... Try this:

this.Top = (this.Owner.Height - this.Height) / 2;
this.Left = (this.Owner.Width - this.Width) / 2;

actually you should set the Location property. the top and left are old vb'er ways

plus the form property has a center option property

It's really irrelevant, a Location property is simple defined as a Point structure that sets the Top and Left properties of the form.

Hiding columns in a datagrid

Ista30-Jul-03 10:50

30-Jul-03 10:50

A datagrid on a windiws form

I have a class called CSchedule

I created a System.Array to house a collection of CSchedules

when I set it as the data source it makes all columns available but I want to hise them.

Since its an array the TablesStyles collection shows a 0 count. How do I achieve this in the correct way?

sorry I don't know the specific code off hand, but this might get you in the right direction...

grab the column object from the columns collection on the datagrid and set its Visible property to false...

that is how I do it in asp.net, but it shouldn't be all that different in win forms.
