Seriously, did you even try?
Google "P/Invoke Wizard", and it's in the very first link.

I am writing a diagnostic tool for our application. This tool has to find and display if our website is added as a trusted site to internet explorer or not.
How can I find this? Can I find this from registry or somewhere else?

Is there any way to produce a new color by mixing two or more colors?
If yes then how do I mix two or more colors such that the new color is no way near the input colors (colors to be mixed)
By near I mean the new color must not be lighter or darker (intensity) color of the input colors.
Thank You.

I have main form that loads other UCs.
When I load certain UC, it loads data for that UC.
On each UC, I have buttons (eg. delete, add etc.).
I want that when I click on add button to add some data, automatically after adding that certain data, UC control reloads.

At first, what ASP.NET or WinForms platform do you use?

It's Windows Application.

Hello Everyone,
How can one detect if a printer is connected to the system or not.
I used the class System.Management.ManagementObjectSearcher class as follows :
System.Management.ManagementObjectSearcher searcher =
new System.Management.ManagementObjectSearcher("SELECT * FROM Win32_Printer");
the searcher.Get()returns printer objects even when not conneted to a printer. It detectes all printers that are installed on my computer.
and when the user clicks on Print (when offline) it throws an exception. How can I prevent this.
Can someone help me on this.
Thank you

Hi,
I have generated a report using Crystal reports. The crystal reportviewer displays the report.
so as to automatically print the report i have a statement :
crystalReportViewer1.PrintReport();
When this statement is executed the Printer dialog box appears. How can this be disabled using c#.
Thanks for your help in advance.

At least I'm pretty sure there isn't a sql problem, the stored procedure works fine in query analyzer, but when I attempt to use it in my program it throws a SqlException:
Line 1: Incorrect syntax near 'NIDB_NIDBArticle_Search'.
Here is the SP:
<br />
CREATE PROCEDURE dbo.NIDB_NIDBArticle_Search<br />
(<br />
@term varchar(100)<br />
)<br />
AS<br />
SELECT<br />
a.article_id AS [ID],<br />
a.main_entry AS MainEntry,<br />
auth.last_name + ', ' + auth.first_name AS Author,<br />
ed.last_name + ', ' + ed.first_name AS Editor,<br />
a.assigned_word_count AS AssignedWordCount,<br />
s.status AS CurrentStatus <br />
FROM<br />
ARTICLE a<br />
JOIN [USER] auth ON a.author_id = auth.user_id<br />
JOIN [USER] ed ON a.editor_id = ed.user_id<br />
JOIN ASSIGNMENT m ON a.article_id = m.article_id<br />
JOIN LK_STATUS s ON m.status_id = s.status_id<br />
WHERE<br />
a.main_entry LIKE '%' + @term + '%'<br />
And here is the method, throws the exception when it attempts to fill the DataTable
<br />
public static DataTable Search(string term)<br />
{<br />
SqlCommand cmd = new SqlCommand("NIDB_NIDBArticle_Search", conn);<br />
SqlParameter parm = new SqlParameter("@parm", SqlDbType.VarChar);<br />
parm.Value = term;<br />
cmd.Parameters.Add(parm);<br />
SqlDataAdapter ad = new SqlDataAdapter();<br />
ad.SelectCommand = cmd;<br />
DataTable dt = new DataTable();<br />
ad.Fill(dt);<br />
conn.Close();<br />
<br />
return dt;<br />
}<br />
Any suggestions? I usually use Enterprise Library but for some reason I kept getting an infinite loop when I try to use it in this Windows form.

Set the CommandType property of the command to CommandType.StoredProcedure.

Yes that fixed... I feel foolish because I was thinking about that before I was finished then got distracted. When I came back it never poped back in my head.

Hi
Can anyone offer any advice on how to achieve on demand/paged population on tree controls for performance. How is this usually done in .NET?
Thanks in advance...

You add a "dummy" child node for every node whose real children have yet to be loaded. When a node is expanded you check if it has a dummy node, and if it does, remove the dummy node and add the real child nodes. The dummy node might have Text of "*" or some value which is meaningless in the context of your application.
The "advanced demo" in the sample app for my TreeViewWalker article uses load-on-demand: http://www.codeproject.com/cs/miscctrl/TreeViewWalker.asp[^]

private void DeactivateControls(ControlCollection ctl)<br />
{<br />
<br />
foreach (Control ctrl in ctl)<br />
{<br />
if (ctrl is MyTextBox)<br />
((MyTextBox)(ctrl)).EnabledSpecial = false;<br />
<br />
else<br />
(ctrl).Enabled = false;<br />
<br />
if (ctrl.HasChildren)<br />
DeactivateControls(ctrl.Controls);<br />
}<br />
}
MyTextBox.EnabledSpecial is still true after I try to set it to false in this method. What do I do wrong?

That depends on what the property EnableSpecial does. Without seeing that code, who knows what is going on?

I didnt show the enabledSpecial since I know that's not where the problem lies, it works in many other places.

If you know that that's not where the problem lies, and there's nothing wrong with the code you posted (except overuse of brackets), and you're sure there's a MyTextBox in the control tree, and you're sure you're calling the method, then obviously your code must work. So there's no problem.
