Hi,
I will not discuss if it is reasonable to display that much lines - you say you need it's ok for me.
I bump in a similar problem , I needed to add lines (trace lines) on a screen as fast as possible.
I made several experiment : listBox , listView, richTextBox , (even webBrowser ...)
It turns out that richTextbox was the fastest , and that the speed to add new line was constant , whatever was the numer of lines already added.
Of course in this case you shouldn't add lines one by ones , but all in one call.
Just set the rtb not to be editable.
Even handle the line selection by yourself.
And you will get a super fast , super basic ListBox 
Hope it helps

Hi girm,
thanks for your answer,
yes, sometimes it is necessary to add as many lines as mentioned.
I think Listbox ist the best option to use in this case.
my code snippet:
this.ListBox1.DisplayMember ="column";
this.ListBox1.DataSource =dt;//dt: DataTable

If you rewrite them as C++/CLI classes, it is. Otherwise, you have to convert to C#, or put them in a dll and you can then use methods in the dll, but not classes as such, via p/invoke.

I am not sure what to even call my question so I couldn't make a better subject. Sorry about that.
I have been making a custom web user control for sometime now and I am quite pleased with the results.
Only one more thing I want to get it to do. My control has a table in it with a method to add cells. I can add anything into the cells as I want as you would normally be able to with a table.
How can I get my control to allow this type of mark up as normal controls do?:
<table><asp:Button ID="btnTest" runat="server" /></table>
I want to be able to do this:
<custom:MyControl ID="myControl" runat="server"><asp:Button ID="btnTest" runat="server" /></custom:MyControl>
I want my control to add the button automatically by calling my code of choice. Any leads in the right direction greatly appriciated!

how to create partial class in c#.net ?
|
|
|
|
|
Do you even know what that means??
A partial class mearly exists acrossed two different source files, but you have to tell the compiler to expect the class to be define in multiple files using the partial modifier.
Read this[^] for everything you need to know about "partial classes".
|
|
|
|
|
Yes i know is different file! but my problem is how to insert a partial class in my project.? Thanks in advance.

Add a class. Add the partial keyword. Add another file, and edit it to be another partial file for the same class.

R u a Student or Developer?
Partial Class is :
Using the partial keyword indicates that other parts of the class, struct, or interface can be defined within the namespace. All the parts must use the partial keyword. All of the parts must be available at compile time to form the final type. All the parts must have the same accessibility, such as public, private, and so on.

code follows:
foreach (System.Diagnostics.Process proc in System.Diagnostics.Process.GetProcesses(MachineName))
{
try { textBox3.AppendText("Proc Name: " + proc.ProcessName.ToString() + " @ " + proc.StartTime.ToString() + "\n"); }

Couldn't connect to remote machine

Try with LOGON32_LOGON_NETWORK (value 3) as LogonType, the token returned by LogonUser is an "impersonation token", such a token CANNOT be used in WindowsIdentity.Impersonate() in order to access network resources.
Then go with the code.
Regards,
Satips.

i understand the idea kinda of but how would i put that into code ( i will be off googleing this but if you have an example handy i could use the help)
|
|
|

|
System.Diagnostics.Process[] ipByName = System.Diagnostics.Process.GetProcessesByName("notepad", "192.168.1.19");
Ive also tried something like this

Are all these machines in the same domain, or is this a Workgroup environment? If domain, then the code has to run under an admin account that the domain trusts. If workgroup, then the Admin account username AND password must match those on the machine that's running your code, exactly, meaning exact same username and exact same password.
This really isn't caused by a problem in your code. It's more of an understanding of how Windows networking works.
