Hello, the codegurus around the world.;)
How about using WIN32 API - SendMessage function.
As you know, we can import this API by Dllimport.
In fact, I have an idea to fire the event of some control by
firing by the other control.
(However, I didn't check all events yet?)
Or, we can use WinPros function to check all events?
Please, don't send me your email about your programming questions directly.
However, if you believe that you gives me some benefits, you can send me your email.
Have a nice day!

I have a problem displaying an array of files in a listbox
my code for the array is:
string[] files = openFileDlg.FileNames;
and I looked up the bestway to add multiple files to a listbox and came up with this:
lstFiles.Items.AddRange(files);
the problem is that my last file when added this way is lost. I also tried setting the datasource to files:
lstFiles.DataSource = files;
but that did not work either. And forced redraw and reinitilization of the list box evertime my OpenFileDialog was called. My problem I think has to do with improper indexing of files... I say this because I cannot select one file and have it display (it comes up blank) but if I try to open it again it is there. So once my files array first becomes initilized it works.
I'm sorry if this question has been asked before but it's late and I have been searching the newsgroups and MSDN and just can't seem to find the answer... Thanks for your help

Freaky. Just as a matter of course...are you sure you clicked the OK button? It is, after all, late...right? (Not here. It's only 3:30 PM)
But that's wierd. 'Cause I've written the same code before and it's always worked for me. 
[edit]Actually, I just did: fileList.Items.AddRange(fileDialog.FileNames);[/edit]

I figured it out... It was about 12:30 am when I posted my question and I will use the lateness of that as an excuse  The answer? I have my listbox contained by a panel... The panel was expanded the entire top of the app (eg. under the title bar) so guess what when I set the docking on the listbox to fill... Yep it cut off the top line of my files... Do I ever feel dumb now

I want to ignore the mouse click event means whenever the event fired it just get ignored (nothing happen). For example I have a TextBox but when I click on it nothing happen, it just ignores the click event. I don't want to use the Enabled property cause it changes its apperance.
Thanks in advance.

Just don't write a method that fires when it's clicked...

Usually in a case like this I reate a new class derived fromm the control that I wasnt to modify, then basically override those event methods. Might be the long way to do it....

Hi!
I don't know if this really is a good idea. Because you user expects a visual feedback. If you disable the listbox, let it look disabled and don't fool your user.
But if you want to do it, do the following:
1)Derive a class from TextBox
2)Override WndProc. And call the base-class method on all messages except WM_CLICK. This should work.
Cheers

I agree what u said and I tried the way you suggest it works great. But there is a problem it can be a expensive call, cause it goes in WndProc all the time cause events are firing all the time. Is there another way, like just detach that attached event. I will be really thankful to you.

Hi,
This code works on 2000/XP plateform but not on NT4 SP6a
[code]
socket.SetSocketOption(SocketOptionLevel.IP,SocketOptionName.HeaderIncluded,1);
[/code]
Does someone have an idea why ?
Thanks.

Thanks to those who answered earlier. I have two combo boxes which show the databases and tables in my DB. When I change the table combo, the DG shows the tables contents. The code now looks like this:
m_dsTables.Clear();
dataAdapter.Fill(m_dsTables);
dgTables.Expand(-1);
The call to Clear() stops my grid from having the old data in it, but the old columns are still there - how do I delte them ?
The call to Expand(-1) expands the + button in the datagrid so I see the word 'table', but I still need to click on this word to show the table. I just want the table to be shown and to remain visible, can I do that programatically ?
This datagrid looks cool, but right now I am overwhelmed by the number of methods it has, and it's not covered in the Petzold book

As per usual, it's a case of ask and ye shall work it out yourself.
m_dsTables.Clear();
dataAdapter.Fill(m_dsTables, m_sDBName);
dgTables.DataSource = m_dsTables.Tables[m_sDBName].DefaultView;

If there are 2 window applications(if run the exe file, it will pop up a window UI, and input the parameters there). The first one is to do the file format convertion of A to B, and the second application is to do the file format convertion of B to C. Now I want to write a Console application in C# which will call these 2 applications to do the job of converting A to C. Anybody knows how to do it? Thanks!

How do I pass an array from C# to a COM object.
What is the method parameter syntax for COM object and how does C# use the COM object
|
|
|
|

I do something like that:
<br />
public int[] ColumnOrderArray<br />
{<br />
get<br />
{<br />
int iCount = m_ctrl.Columns.Count;<br />
int[] array = new int[ iCount ];<br />
<br />
IntPtr ar = Marshal.AllocHGlobal( iCount * Marshal.SizeOf( typeof(int) ) );<br />
Marshal.Copy( array, 0, ar, iCount );<br />
<br />
WindowsAPI.SendMessage( m_ctrl.Handle, LVM_GETCOLUMNORDERARRAY, iCount, ar );<br />
Marshal.Copy( ar, array, 0, iCount );<br />
Marshal.FreeHGlobal( ar );<br />
return array;<br />
}<br />
set<br />
{<br />
int iCount = m_ctrl.Columns.Count;<br />
if( value.Length > iCount || value.Length < iCount ) return;<br />
<br />
IntPtr ar = Marshal.AllocHGlobal( iCount * Marshal.SizeOf( typeof(int) ) );<br />
Marshal.Copy( value, 0, ar, iCount );<br />
<br />
WindowsAPI.SendMessage( m_ctrl.Handle, LVM_SETCOLUMNORDERARRAY, iCount, ar );<br />
Marshal.FreeHGlobal( ar );<br />
}<br />
}<br />
For better solution look into MSDN by search criteria: Array NEAR COM NEAR Marshal

The following code snippet:
namespace myns
{
///
/// ADO.NET data access using the SQL Server Managed Provider.
///
public class Database : IDisposable
{
public int RunProc(string procName)
{
this.close();
}
private SqlCommand CreateCommand(string procName, SqlParameter[] prams)
{
open();
}
private void Open()
{
....
}
public void close()
{
....
}
}
}
I want to know why he use this.close(),but not this.open();
Or open(),but not close()?
Does it relate to public or private define?
I am not using "this" pointer much.
So please give me some guiding or introduce me some online resources.
Thanks.

Generally the only reason to use this is to get a list from intellisense. The 'this' scope is implied, it will be the first to be looked up, I believe. I doubt there is a reason stronger than that.

Also for disambiguation in, e.g., parameterised construction...
class Customer
{
Customer(string firstName)
{
this.firstName = firstName;
}
private string firstname;
}

there is a very good reason.

I, too, am still learning about all of this stuff. So I probably know only enough to get myself in trouble. 
This is what I know so far about this
If you have multiple threads of an object, I believe that this will differentiate between current thread and some other thread. (or maybe the parent thread(???))
In all of the web examples I've seen there is a heavy use of this for accessing the form fields.
In inherited classes, this also identifies you are refering to a property/method within THIS class vs. the BASE class. (even though you cannot access base methods WITHOUT the base qualifier!)
With the exception of those two reasons, this just makes it easy to pull up an intellisense box while coding.
