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.

Hello
i have wasted lot of time.
1I want to put a command button in the datagrid in one of the column. I got a piece of code from this site and i have added to my project. it is working fine except i am having a major issue. when i click on the button, i am poping a form. if i click again, the form gets popped up twice, if i click again, 3 times the form gets popped up. is it due to the events get added up every time when i click on the button. my code is like this
buttonColStyle = new DataGridButtonColumn(1)
buttonColStyle.HeaderText = "Browse";
buttonColStyle.MappingName = ObjDataColumn.ColumnName;
buttonColStyle.CellButtonClicked +=
new DataGridCellButtonClickEventHandler(HandleCellButtonClick);
GridTableStyle.GridColumnStyles.Add(buttonColStyle);
this.DGDetails.MouseDown += new MouseEventHandler(buttonColStyle.HandleMouseDown);
this.DGDetails.MouseUp += new MouseEventHandler(buttonColStyle.HandleMouseUp);

dear wilson you have to check the instance of the popped-up form every time you click the button. If form's instance already exist then dont make use of new keyword just use the form's "show" method.
Use this method to check instance of the form (may be this could be useful)
//***********Start**********
private Form isFormAlreadyLoaded(Form ToBeLoadedForm)
{
foreach (Form LoadedForm in this.MdiChildren)
{
if ((LoadedForm.Name == ToBeLoadedForm.Name) && ((LoadedForm.Text.Trim ()) == ToBeLoadedForm.Text.Trim()))
{
return LoadedForm;
}
else
{
return ToBeLoadedForm;
}
}
return ToBeLoadedForm;
}
//***********End**********

I have a Windows application written c# 1.1 that uses embedded crystal reports. I have 60 users who all use the exe which is accssed from a shared folder on the network. The problem is I still need to install the application on all client machines so as crystal registers properly. Is there away around this so as I dont have to install the application on all client machines?

can we fast track or slow track any video in C# to produce the effects as are seen now-a-days during CRICKET matches...i know ASF files can be slow/fast tracked using the windows media player object........but is there any better way....

I have a form i am overriding the WndProc and i am trying to get a scancode for a WM_CHAR so i can get the correct char text. This is for internationalization. I have read that the key's scancode is embedded in the LParam parameter of the WndProc message. How do i extract this?
Below is some of the code i am working on. It is very possible i am tackling the problem wrong? I am not a C++/Win32 expert. From all my reading it appears that to have the best chance at converting a foreign char correctly one uses a combination of: 1) keyboard layout; 2) scancode; 3) virtual key. I appreciate the advice. I have blown quite a few brain cells working on this.
protected override void WndProc(ref Message m)
{
switch (m.Msg)
{
case WM_CHAR:
// get keyboard layout
// keyboard layouts map scan codes to virtual keys;
IntPtr keyboardLayout = GetKeyboardLayout(0);
// get keyboard state
byte[] keyboardState = new byte[256];
GetKeyboardState(keyboardState);
// ???
// get scan code
// get virutal key
Keys virtualKey = m.WParam;
// convert scan code to ascii
StringBuilder result = new StringBuilder();
result.Capacity = 2;
if (ToAsciiEx(virtualKey, scanCode, keyboardState,
result, 0, keyboardLayout) == 1)
// display char text
this.Text = result;
}
}

In an open source programm called Putty i found the answer. I do not fully understand the bit shifting and &ing but it works. I know it is a rubik's cube type maneuver to "pop out" a certain set of bits. It extracts the scancode from the LParam value. For anyone who wants to save 20 hours of research. The below is not an obvious find if you tried researching the internet starting with zero knowledge.
For WM_KEYDOWN
uint virtualCode = (uint)m.WParam;
uint keyState = (uint)m.LParam;
uint scanCode = keyState >> 16 & 0xFF;
Here you have the core values you need to resolve keys to text using various Win32 functions.
|
|
|
|
|
Keystate is a 32 bit int: AA BB CC DD (AA BB CC and DD are placeholders for the 4 bytes)
After shifting it 16 bits you have the value: 00 00 AA BB
Finally anding with 00 00 00 FF will zero out the value in the 3 high bytes (only needed in one of them) leaving scancode containing: 00 00 00 BB
