Thanks for the link.
Have you ever tried that function before ?
I'm trying it using:
Username = ""
Password = ""
Domain = ""
And..the return value is TRUE... Smile | :)

That means user is valid.

I am using fingerprint reader.
Need help to capture the image in my application from fingerprint reader.

What's the mechanism used to capture image in fingerprint reader. Does it scans the image?

You'll need the SDK from the manufacturer of the Fingerprint Reader. Without it, you're not going to get anywhere.

Its true that you need SDK from the product manufaturer.
But in some cases it works with other sdk's too.
Check this article and see if it can help you.

What is the best way to populate a context menu with data from a DB when it is clicked on?

Basically I am trying to create a context menu from a notifyIcon and populate it with names & numbers when it is right clicked... I can get the data from the DB, I just need to know how to put this data into the menu... Any ideas or pointers?

Thanks in advance,

Phil

You can dynamically create the context menu when the click is performed. Also you can use one context menu and just clear the menu items and add new items at runtime. The code below is .NET 2 same logic different control in .NET 1.1

contextMenuStrip1.Items.Clear();
ToolStripItem ts = null;
for(int i=0;i<5;i++){
    ts = contextMenuStrip1.Items.Add(i.ToString());
}
contextMenuStrip1.Show();

We can create context menu in this way but also we need to handle events for these context menus. To do so we can create a common event for all menu items and then based on the context name respective code can be executed.

Impossible itself says I M Possible.

All you have to do is bind your events at the time you create each context menu item. You would basically be doing in abstract code, what the designer does with hard coded code.

foreach ( string element in myListofThings )
{
     ToolStripMenuItem menu = new ToolStripMenuItem();
     menu.Name = element.ToLower();
     menu.Text = element;
     menu.Click+=new SystemEventHandler(HandleContextClick);
     myContextMenu.Add( menu );
     foreach ( string subElement in SubElementList )
     {
         ToolStripMenuItem submenu = new ToolStripMenuItem();
         blah blah blah
         submenu.Click+=new SystemEventHandler(HandleSubContextClick);
     }
}

If you've got a lot of work being done in one window, use a background thread to perform the work. Have a look at the BackgroundWorker component[^].

If you really need two separate windows for doing processes, you may want to also consider implementing both windows inside of an MDIParent, in addition to using a BackgroundWorker thread.

i guss i had similar question before ,so search for my question "how to print part of the document" my member name khalid sabtan
you also have to do the following
1- make a textbox at the location you want to print on(inside your document)
2-bring the cursor inside that textbox and make a book mark by msword and give it a name such as mybookmark1
3-inside your c# program send your string to that bookmark, it should land on that textbox
4- to undestand how to send 2 the book mark
look at this

Object name = mybookmark1;
Word Range rng = oDataDoc.Bookmarks.get_Item(ref name).Range;
rng.Text = "Hellow TAREQ F ABUZUHRI"

C# Newbie: What is the ":" for?? [modified]

Hey guys.

I just started a new job which requires C# skills so I'm trying to get myself up to speed and while I've been able to understand most of the stuff so far, one thing I don't understand is what is the purpose of the ":" and everything after it when creating a class?

For example, what does the ":" mean in the following line and what is the purpose for "ExcelReport, IReport":
------------------------------------------------
public class SampleClass: ExcelReport, IReport
-------------------------------------------------

This code is basically from one of their applications. It writes a report to an excel file.

Oh, also if it's not too much trouble, can anyone explain what ":base()" is used for? For example:
---------------------------------------
public SampleClass(FileInfo fileName)
: base(fileName)
---------------------------------------

Thanks again guys.

inheritance

SampleClass is inherited from ExcelReport.

:Base(fileName) calls the constructor of the base class.

Hope this helps.

The : in the class declaration indicates that your class will inherite from some other class. In the example you gave:

public class SampleClass: ExcelReport, IReport

SampleClass inherits from the class ExcelReport, and the interface IReport.
