For the past few days I've been searching for a way to see who is loggin in on a terminal/server without having log on yourself and check.
Originally I had planned to use WMI, but I ran into too many difficulties with security issues. I've recently switched to trying a RPC program that I can just load on every computer and have it check who is logged on and toss me back the info.
However, during this entire process I've felt like I'm inventing the wheel all over again. Surely there is someone who has done this before? Does anyone know of any programs/resources I could turn to?

Have you eliminated the Terminal Services API?

I think I'm going to run into the same security problems I did with WMI, but I will look in to that more.
Does anyone have any other suggestions?

Well security issues exists for a reason. You might consider just digging in and getting up to speed is a better approach than an unsecured solution.

I have a usercontrol on a form when i click on the usercontrol I changed the control Style. But my Keydown and KeyPress events are not being fired.
public UserControl1()
{
InitializeComponent();
this.MouseClick += new MouseEventHandler UserControl1_MouseClick);
this.KeyDown += new KeyEventHandler(UserControl1_KeyDown);
this.KeyPress+=new KeyPressEventHandler(UserControl1_KeyPress);
}
void UserControl1_KeyPress(object sender, KeyPressEventArgs e)
{
MessageBox.Show("Presss");
}
void UserControl1_MouseClick(object sender, MouseEventArgs e)
{
MessageBox.Show("mouseclick");
this.BorderStyle = BorderStyle.Fixed3D;
}
void UserControl1_KeyDown(object sender, KeyEventArgs e)
{
MessageBox.Show("down");
}

The problem you're running into is that you're handling the Key events of the UserControl, which will never have the input focus. The constituent controls of the UserControl get the focus, not the UserControl itself. A UserControl is a container, not a focusable control. This is why the UC keyboard events never fire.

Thanks for answering but what i want if the usercontrol has focused then listen for keyDown event and keyPress events. How can i achieve this any example please

Not possible. I just told you the UserControl cannot be focused. The constituent controls inside the UC can have the focus, but you'll have to handle the Key events for each of those controls in your UC code.

Where's PreTranslateMessage() when you need it the most?

I guess it's hiding inside the KeyPreview = true; in the Form class. Too bad it doesn't apply to UserControl.

Is there a simpler way to load a DataTable from XML where I need to qualify the XML with an XPath? Currently, I have:
DataTable dt=new DataTable();
XmlNodeList nodeList=xdoc.SelectNodes(rootName+"/"+path);
if (nodeList.Count != 0)
{
CreateColumns(dt, nodeList[0]);
}
foreach(XmlNode node in nodeList)
{
DataRow dr=dt.NewRow();
foreach(XmlAttribute attr in node.Attributes)
{
dr[attr.Name]=attr.Value;
}
dt.Rows.Add(dr);
}
Is that the best way to do this?

I don't know if simpler or better is how you might describe this but I would think you could work with the XPathNavigator library and derive from XmlReader passing calls on to the navigator so you can use DataTable.ReadXml( XmlReader).

Ah, the XPathNavigator! I forgot about that. Thanks, I'll take a look.

Hi,
I am no expert on RichTextBox, but the way I understand it is: RTB.Text contains the
text without formatting; and RTB.Rtf contains the RTF representation of the text, including
formatting commands (which is not HTML), so only an RTF-capable receiver would be able
to present it the way you hope.
Maybe your sender app should take the RTF, convert the RTF commands to HTML commands,
then send it.
Hope this helps.

In the TreeView control, when you expand a parent node, its children "slide" in to view, and "slide" out again when you collapse the parent node. I thought there was a way to stop this, and have the children just appear, rather than slide, but I can't seem to find it. I've tried searching Google for both C# and C++/Win32 examples, but to no avail.
Thanks in advance.

I guess you are running Vista? Because there is no sliding in my tree controls on XP Pro

If it were only that easy.  No, actually, I'm using Windows XP, SP2, with VS.NET 2005, and the standard TreeView control. I should have mentioned (my bad) that it only seems to happen when there are several (say, over 40) children in a node. If there are only a few items, the expand/collapse is instant.

umm yeah, that would have helped. But I just made a treeview control with 100 children under the root and there is no sliding when I expand/collapse it. What else did you leave out?

No clue. Apparently it's another one of those Windows "features" that work for some and not for others... I'll keep looking. Thanks.

What you're seeing isn't an intentional sliding effect, it's a slow redraw (actually, it's "tearing" - the drawing passes are falling between screen refreshes). All of the nodes below the ones being collapsed have to be moved up and redrawn, and what you're seeing is the redraw versus the refresh rate of your monitor.
There's no sliding. If there were, it would be consistently and always obvious. There's also nothing you can do about it.

Greetings,
I am working on a project that is way to big for me, but I thought I would try and tackle it anyway as an opportunity to learn more.
Within my application I am trying to develop a static method that I can use to convert a time such as 1:15 (1 hour 15 minutes) to a decimal.
I understand the formula, since I used it in Excel before. I need to take the input value from the user, pass it to the method, and multiply it by 24. This will give me the decimal value that I need.
My question is strangly simple, and I am still just stumped by it... what data type do I need to use to get my user information into my method? It's just the colon in the user value that throws me off.
Can I just take in "xx:xx" as a string value and then use "Convert.ToDecimal"?
I'm sorry if I am not clear enough. If it's not, let me know and I will be happy to rephrase.

Hi,
if the method is to accept a date, you basically have two choices:
- pass it a DateTime instance
- pass it a string representing a date, and use DateTime.Parse inside the method to decode it
whatever you choose the method will need DateTime.Hours and DateTime.Minutes to calculate
the integer value you want.
I don't expect Decimal type will be of much help.

Thank you very much! I really appreciate it!

I have a com object dll file called MyCom.dll with some classes, interfaces, methods and events.
I can add it as a reference to my project in visual studio IDE and create an instance from one interface that i need:
MyDllLib.InterfaceName myobject = new MyDllLib.InterfaceName();
I can also access all the events and methods for this interface via myobject.
So by some reason i dont want to add this com dll file to my project references and dont ask why! My question is how can instantiate an interface from a com dll file and access it's methods and events.
If i dont add it as a reference in .Net IDE so i can't reference it.
Could someone recommend the best solution for this.
Thank You,
