You want it globally or with context to your application only? To find find it globally, you can use GetCursorPos()[^]. It is a Windows API function and you will need to import user32.dll to use it. (Just scroll down to the bottom of the page, the syntax to import it into your C# application is specified there).

Or if he's using WinForms, he can just use Cursor.Position (which internally calls GetCursorPos).

Thanks for your comments, Nish. 
There's way too less information provided (it isn't clear what he's using or not), so I just wanted to help the poor OP (who had received no replies that can help him until then) with an answer that would work for sure. May not be the simplest answer though.

I thought your answer was very good. And the previous answers he got were all fairly useless.
Btw, I got linked here from the Lounge thread.

Does that even compiles? I believe it should not. Read a book or the MSDN documentation for Thread.

I am transitioning from the mainframe to C#. I have so far been able to build an XML doc containing a multi-column table.
I have been able to create the code to read that back in, but I can't figure out how to populate some sort of multi-columned collection or whatever that would contain rows of multi-column data that mirrored the XML table contents.
HELP!!!! and THANKS!!!

Go for DataGridView. Create a Dataset using your XML and ReadXML method and assign it as DataSource for your DataGridView.

what's mean the <> command in the next line :
List<item>
{
...
}

First off, two bits to make it easier on us all.
1) Use the "code block" button above, even for small examples.
2) Just above the "Post Messaeg" button is a box marked "Encode HTML tags when pasting" this means that < and > are displayed corretly, with any contents.
So, I assume what you meant was:
What's does the <T> mean in a List<T>?
A old fashioned List can hold any type of object, so you could use:
List list = new List();
list.Add(new TextBox());
list.Add(123);
list.Add("Hello");
without complaint, if you meant to or not.
When you came to use list though, you would have to check what type of object you had, or a run time error would occur.
Newer versions are type safe - you can only include the declared type:
List<TextBox> list = new List<TextBox>();
list.Add(new TextBox());
list.Add(123);
list.Add("Hello");
would give compiler errors for the integer and string.
No trees were harmed in the sending of this message; however, a significant number of electrons were slightly inconvenienced.

I have the following XML:
<?xml version="1.0" encoding="utf-8" ?>
<string xmlns="http://none.none.none/webservices">
<TREENODES xmlns:sql="urn:schemas-microsoft-com:xml-sql">
<TREENODE code="1" text="None" >
<TREENODE code="2" text="America" >
<TREENODE code="16128" text="AUTOS">
<TREENODE code="ATO" text="ATO" />
<TREENODE code="ATO" text="ATO" />
</TREENODE>
</TREENODE>
</TREENODE>
<TREENODE code="11" text="None" >
<TREENODE code="21" text="America" >
<TREENODE code="3" text="AUTOS">
<TREENODE code="ATO44" text="ATO5" />
</TREENODE>
</TREENODE>
</TREENODE>
</TREENODES>
</string>
And this code to read the xml into class Hierarchy.
void client_ReadCompleted(object sender, ReadCompletedEventArgs e) {
if (e.Error == null) {
string s = e.Result.ToString();
XDocument document = XDocument.Parse(s);
var retVal = (from treeNode in document.Descendants("TREENODE")
select new Hierarchy() {
Code = treeNode.Attribute("code").Value,
Text = treeNode.Attribute("text").Value,
}).FirstOrDefault();
retVal.Hierarchies = GetHierarchy((from treeNode
in document.Descendants("TREENODES")
select treeNode).FirstOrDefault());
Hierarchies = retVal.Hierarchies;
}
}
public static List<Hierarchy> GetHierarchy(XContainer root) {
List<Hierarchy> retVal = new List<Hierarchy>();
var children = from treenode in root.Descendants("TREENODE")
select treenode;
foreach (var treenode in children) {
Hierarchy node = new Hierarchy();
node.Code = treenode.Attribute("code").Value;
node.Text = treenode.Attribute("text").Value;
node.Hierarchies = GetHierarchy(treenode);
retVal.Add(node);
}
return retVal;
}
public class Hierarchy {
public string Code { get; set; }
public string Text { get; set; }
public List<Hierarchy> Hierarchies { get; set; }
public Hierarchy() {
Hierarchies = new List<Hierarchy>();
}
}
However my construction/population of the class is not the same as the XML. I can not see the error.

FYI: I should have done
public static List<Hierarchy> GetHierarchy(XContainer root) {
List<Hierarchy> retVal = new List<Hierarchy>();
var children = from treenode in root.Descendants("TREENODE")
select treenode;
foreach (XNode xn in root.Nodes()) {
Hierarchy node = new Hierarchy();
node.Code = ((XElement)xn).Attribute("code").Value.ToString();
node.Text = ((XElement)xn).Attribute("text").Value.ToString();
retVal.Add(node);
node.Hierarchies = GetHierarchy((XContainer)xn);
}
return retVal;
}

Hi all,
I'm having trouble suppressing mouse clicks globally. There are a lot of articles about how to connect to mouse and keyboard hooks and how to suppress a keypress but how would you stop, say, a right click in Windows?
Thanks in advance.
|
|
|
|
|
Stop a right click where?
If it's your application just don't handle the event.
only two letters away from being an asset
|
|
|
|
|
to allow your application to prevent a right click being actioned in Windows by using your application as a form of mouse hook that doesn't pass on any right clicks to any other applications/windows
|
|
|
|
|
Have you tried looking here[^]?

|

thanks for the reply. Yeah I have read that article but I can't work out how to prevent the mouse click event being passed on to other windows. With the keys you can just set the e.handled=true but there doesn't appear to be a similar thing for the mouse.

Hello, i need help in some subject i can't handle with for few days. lets say i have form that handle with some rent order (like....billiboards) after the user choose the number of the billboard and the Location and everything else, he need to choose 2 dates. one for the publish day and one for the getOFF day. i have odbc database that hold all the information about the billboards etc... how can i make some "if" or queries that will check that this billboard is not ordered in that range of days? for now i only have the insert handle. PLEASE HELP.
in abstract way = the code have to check the "signNumber" too not only the range between dates. in ABSTRACT = "take the signNumber and check if is available between that two dates if yes, insert to the database if not throw messagebox - NOT AVAILABLE"

First, stop using string concatenation to form your sql statements. There has been enough written about how poor this is, for number of reasons, that you should have seen something about it. Use a stored procedure.
SQL
IF( NOT EXISTS(SELECT signNumber FROM orders WHERE Date BETWEEN start AND end))
INSERT...
RETURN 1
ELSE
RETURN 0
Code
if( SQLCommand.ExecuteScalar() == 0 )
display mbox
only two letters away from being an asset
