Dear All, I have an application which uses impersenation to login to remote machine in same domain.
It works very well in Windows XP, but it doesent works in Windows Server 2003.
here i have the code

void login(string username,string archieveUserpassword,string domain)
{
IntPtr accessToken = IntPtr.Zero;
if (LogonUser(username, domain, archieveUserpassword, LOGON_TYPE_INTERACTIVE, LOGON_TYPE_PROVIDER_DEFAULT, ref accessToken))
{
WindowsIdentity identity = new WindowsIdentity(accessToken);
WindowsImpersonationContext context = identity.Impersonate();
dir[]==Directory.GetDirectories(fullArchievePath);
MessageBox.Show(dir[0].ToString());
}
}

It works very well in Windows XP, Y not with Windows Server 2003?

well, if i use this code in my windows xp pc then i can login to with specific user name and password and then it messages the directory. The same code doesent work in windows server 2003. As i am not returning any error message from that. The login fails in remote server which means the method login returns false. I have bellow question.
Can we login with specific account to remote server while we are not in that dommain? if yes any suggestions or idea.

It would still help if you can tell me what method is actually failing. I'll assume it is LogonUser and I'll also assume that it is PInvoking to the Win32 API. After it fails by returning false, you can find the error code by calling Marshal.GetLastWin32Error().

i am getting the error bellow

else
{
int error=Marshal.GetLastWin32Error();
MessageBox.Show("Failed To Login\nError Code:\t"+error);
}

well our win server 2k3 has two NIC
NIC A connected to IP 10
NIC B connected to IP 192

i recieved the error code: 1311

I then disabled NIC A because remote server has IP 192

now i am getting the following error code: 1789

Well according to the documentation[^] 1311 is ERROR_NO_LOGON_SERVERS - There are currently no logon servers available to service the logon request. 1789 is ERROR_TRUSTED_RELATIONSHIP_FAILURE - The trust relationship between this workstation and the primary domain failed. Not sure how to fix it, but you may want to google ERROR_TRUSTED_RELATIONSHIP_FAILURE and see what you can come up with.

Listboxes, Strings And Arrays

Hi,

I'm probably missing something really simple here, but i'm stuck.

Basically I have a listbox, which a user puts items into via a textbox and button, this works fine, the items go in.

Now, on exit the items save to a text file, this also works fine, ive checked all the items are contained in the text file. Now, when the user re-opens the application there is a button called load previous items, when i click this i have a streamreader reading the text document, also works fine, checked with a messagebox, and it saves it to the string

Now, I want the string to be saved into a array which is then put back into the textbox, the problem being, I dont know how to count the items in the string (each on a diffrent line) to put them into a array, and then after that I need a example of adding the array into my listbox.

Im guessing its something to do with the

listbox1.Addrange();

command.

Cheers,
Ben.

If the file content is indeed strings each on a new line, then the easy way is:

string[] lines = File.ReadAllLines(@"c:\Temp.txt");
ListBox1.Items.AddRange(lines);

Which means you don't need to know how many lines there are.

Hi

I am developing a windows application using c#.net
in my application i have two rich textbox controls

if the user enters some text in the rich text box, after the rich text box is completed
he should redirect to the second rich text box
that is when ever the text in the first rich text box is completed
scroll bar should not be visible instead he should be directed to second rich text box

i have to achieve this by with out considering the
number of lines and character count for a rich text box
i have to limit the content in the rich text box to the text which is displayed to the user only.

can any body suggest me how to achieve this ??

Thanks

Hi everyone.... There a lot of examples in the internet that discussed how to send & received SMS messages using GSM modem, messages that are initiated from PC and not from mobile phone... But i never find any program that will monitor outgoing SMS messages initiated from Mobile phone connected to pc....

There are some mobile phones especially china-made mobilephones that don't have an outgoing records stored either in SIM or in Phone memory. I really want to know every message that comes IN and OUT in the mobile phone which is connected in my PC....

Thanks in advance....

Set the size of the drawable part of a form

Hello,

This is probably a dumb question so I'm sure you'll be able to help.

On a typical form; you can set the width & height, but it sets the size of the whole form (including the windows buttons and borders). How to set the size of the drawable part of the form only.

eg: On this window, how to setup the blue part to be 640x480; not the whole thing?

Thank you!

You'll need to set the parent of the new screen to your home-form;

SubScreenForm myForm = new SubScreenForm();
SubScreenForm.ShowDialog(this);

But, you need to tell us what the problem is and how far you you have done.

Use

DateTime.ParseExact("datestring", "formatstring", new CultureInfo("en-US"));

I think this will do the trick.
