Why XML? Can't you export your treeview as a persisting object to disk, i.e. using an ObjectFiler, BinaryFormatter or native object database?

I have a C# DLL that a VB6 app is making a call into. That DLL then starts a thread and returns immediately.
I need for the DLL to raise an event when the thread completes.
I can't use the BeginInvoke technique to start the thread, because I need to override the apartment mode to STA, as interactions with COM objects was failing with "QueryInterface failed".
Therefore, I am using an explicit thread creation, which doesn't seem to provide a callback mechanism.
I can raise a message from the main thread just fine.
I can't raise a message from the worker thread; I get "Object does not match target type".
Is there way that I can invoke a function on the main thread from within the worker thread so that the event originates from the main thread?
Thank you.

i search this topic. and i used codes which is posted before.(about setstyle) However my form flicker. I draw an image, and some lines and points on the same form. So when i refresh it, it flicker.
How can i solve it ?
|

|
|
|
Did you override OnPaint to do the drawing yourself? Did you call SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.OptimizedDoubleBuffer, true) in the form's constructor?
That will work if you do it correctly. Worse comes to worse, just draw to a bitmap, then draw that bitmap to the screen, which will prevent flickering.

That was the longest run-on sentence I've ever seen; it caused me a good deal of pain to read that. Your English could use some help; but I'll assume you're not a native English speaker so I'll try to answer your question anyways.
The RichTextBox probably won't do everything you want it to do out-of-the-box; you're going to have to dig into some Win32 interop to get it to do things differently. Have you read the CP article[^] on customizing the RTB? There's another article on it here[^] that may help you as well.

Hi
I hope someone in here can help me with this issue.
I am trying to write a little application that will give me the information of the directory which is there in the network.
I am able to get the local directory information, but when I tried to access the information of the directory which is in some other
system of the same network I am getting Exception as "Logon failure: unknown user name or bad password."
In fact the directory which I am trying to access is created by myself using another console application.
Here is my code snippet,
DirectoryInfo dir = null;
FileInfo[] xmlFiles;
//get the directory info,
//here test machine is a network machine under same domain
dir = new DirectoryInfo("\\\\TestMachine\\Indexes\\");
//get the information about the subdirectories of dir.
DirectoryInfo[] subDirectories = dir.GetDirectories();
when I try to execute this GetDirectories() method its says "Logon failure: unknown user name or bad password."
So, am doing anything wrong in this code? or is there any other solution to get the directory Info?
Expecting some solution.
Thanks in advance.
Hans.

The Genghis Framework[^], which is free and built on top of the .NET framework, includes functionality for accessing shares and password protected shares.
Also, you can use WNetUseConnection[^] from the PlatformSDK via P/Invoke.

Basically, the remote machine doesn't trust you. You're trying to get the directory of a share on a machine that is not part of the same domain as the machine your code is running on. The SID that you logged in under on your machine isn't known to the remote machine and there is no way for it to know that it can be trusted, so it denies your "implied" login attempt.
You have to establish an authenticated connection to the remote machine before you attempt any file operations on one of its shares. You can use the library Judah suggested to establish the authenticated connection, but you still have to supply it with a username and password that the remote machine will accept as valid.

Hi,
i've tried 'google'ing to find any article on how i might be able to read the metadata of a file or .net 2.0 rc1 assembly that i've built (e.g. the date the file was last modified, or the author of the assembly, it's version etc), but i seem to have hit a bit of a brick wall, i'm sure there must be a simple (or not) way to read this kind of information about a file programmtically.
any help or nudges in the right direction will be greatly appreciated
Thanks in advance.

I'm not sure if it will give you all the info you need, but you can do:
Assembly asm = Assembly.Load(filename);
then use properties/methods of asm:
asm.GetName().Version
You can also get attributes of an assembly by using GetCustomAttributes(typeof(AssemblyTitleAttribute), true)
|
|
|
|

Try this...
using System;
using System.IO;
using System.Reflection;
public class Meta
{
public static int Main( )
{
// First load the assembly.
Assembly a = Assembly.LoadFrom("hello.exe");
// Get all the modules that the assembly supports.
Module[] m = a.GetModules( );
// Get all the types in the first module.
Type[] types = m[0].GetTypes( );
// Inspect the first type.
Type type = types[0];
Console.WriteLine("Type [{0}] has these methods:", type.Name);
// Inspect the methods supported by this type.
MethodInfo[] mInfo = type.GetMethods( );
foreach ( MethodInfo mi in mInfo )
{
Console.WriteLine(" {0}", mi);
}
return 0;
}
}

Hi gurus,
I'd like to know how to do the two following operations on TextBox controls:
- Moving the cursor to the end of the text, so the new added lines are always visible without moving the scroll bar.
- Setting the focus on a TextBox. the Focus() method does not work 
Thanks for the help.

answers:
1. <textboxname>.Select();
SendKeys.Send("{END}");
2. <textboxname>.Select();

1) I have found another alternative by using the SelectionStart set to Text.Length and ScrollToCaret method.
2) The Select() method does not set the caret to the wanted control. Actually the Focus() method was right, the wrong thing was that I was modifying the interface through a secondary thread.
Thanks for the help.
