The LPSAFEARRAY contains VARIANT type of data, any idea about how can I access them?
Thanks for your help.

I am saving data in a text file, how can I delete specific line and how can I make the software remember which lines goes with each data saved?
and also after I delete the lines I want them the gaps to dissappear, since empty lines takes bytes too. How can I do that?

Read the file and create an array each containing a line. Delete the items out the array and write the file back out again.

In the current context there is not enough information to give a valid answer that is anything more than idle speculation.
You are asking for some data to be match up with lines in a file. What data are you talking about?

When writing the file out, don't write out empty lines.

nice way that indeed can work thanks alot

You could read in the data and write out to a temp file at the same time. Then once your done, delete the original file and rename the temp file.

The file system doesn't know about lines, it does not support just removing an arbitrary amount of data in the middle. So, the file system requires that whatever you do, you write a new file to do it.

I would say .ReadLine() and a HashTable should work hand-in-hand and flushing the unique lines onto a fresh file after duplicate-cleanup work is complete.

CAN ANY ONE TELL ME HOW CAN WE CONVERT A MATLAB SCRIPT IN C# OR HOW TO CREATE DLL FILE OF THIS SCRIPT .

Wouldn't this be better posted on a matlab forum?

Please don't 'shout' - read the forum guidelines.
Also, please don't post the same question twice in the forum.
I don't think there is an easy way of converting MATLAB code to C#, other than translating it yourself.
I did find this link[^] to a CodeProject article that explains how to set up an interface between MATLAB and C#.

1 - shout
2 - ask the same question more than once
the answer is no. Matlab is a C++ library, AFAIK.

Handle the KeyPress event raised by the TextBox control and check which key has been pressed. Cancel the key press if the user has made an invalid selection.
More information about handling this event can be found here[^].

Dear friends,
I have Created a windows Service in .net 2005 to find the WMI Classes that are available in a system.
When I invoke this windows service through a web site
I could get all the WMI Classes available in my system.
But it throws an error “Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) “ Like this for the remote System.
Note: I have given the correct User name and Password.
And this same code works fine in windows application,console application and web site for the remote system and local system..
This is the Code:
private string[] GetClassesList(string sIPAddress, string sWMINameSpace, string sUserName, string sPassword, bool bRemoteSystem)
{
int queryClassCount = 0;
string[] aClassList = null;
ConnectionOptions cnnOptions = new ConnectionOptions();
ManagementObjectCollection objClassColl = null;
cnnOptions.Username = sUserName;
cnnOptions.Password = sPassword;
cnnOptions.Authentication = AuthenticationLevel.Packet;
ManagementObjectSearcher searcher = null;
try
{
if (bRemoteSystem)
{
searcher = new ManagementObjectSearcher(new ManagementScope(@"\\" + sIPAddress + @"\" + sWMINameSpace, cnnOptions),
new WqlObjectQuery("select * from meta_class"), null);
}
else
{
searcher = new ManagementObjectSearcher(new ManagementScope(sWMINameSpace),
new WqlObjectQuery("select * from meta_class"), null);
}
objClassColl = searcher.Get();
//aClassList = new string[objClassColl.Count+1];
}
catch (Exception me)
{
MessageBox.Show(me.Message);
}
Friends, Is there any problem in my code?
Any idea’s or Link
Help me
Thank u.

Joe
