No. You're asking in the C# forum, and you can use C# to build an interface. If you want everything done for you in a WYSIWYG fashion, then Access is definately the answer. If you were going to read a flat text file in code, then MSDE is a far better solution.

I am trying to impersonate a user to access a password protected network shared resource. (i.e Start>>Run>>"machine name", then enter user name and password) I am using Win2K. I know that the LogonUser doesn't work on Win2k unless the "Act as part of the operating system" priviledge is set. But that is not an option. I think I might need to use SSPI, but am unsure how to. Here is the code, but because I didn't set the "Act as part of the operating system" priviledge, I get the following error: ERROR_PRIVILEGE_NOT_HELD
1314
[DllImport("advapi32.DLL", SetLastError = true)]
public static extern int LogonUser(
string lpszUsername,
string lpszDomain,
string lpszPassword,
int dwLogonType,
int dwLogonProvider,
out IntPtr phToken);
private const int LOGON32_LOGON_INTERACTIVE = 2;
private const int LOGON32_PROVIDER_DEFAULT = 0;
private void ImpersonateValidUser(string userName, string domain, string password )
{
IntPtr iToken = new IntPtr(0);
try
{
iToken = IntPtr.Zero;
if (LogonUser(@userName, domain, password,
LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT,
out iToken) != 0)
{
WindowsIdentity id = new WindowsIdentity(iToken);
// Begin impersonation
impersonationContext = id.Impersonate();
RevertToSelf();
}
else
{
int ret = Marshal.GetLastWin32Error();
}
}
catch
{}
}
How do I use Windows Impersonation on Win2K and not set the "Act as part of the operating system" priviledge?
Any help would be greatly appreciated.
Thanks in advance!

Hello,
Is there a way of getting a current user logged on the machine?
Thank you.
|
|
|
|
|
using System.Threading;
using System.Security.Principal;
using System.Security.Permissions;
class xxyxyx{
Thread.CurrentPrincipal = new WindowsPrincipal(WindowsIdentity.GetCurrent());
AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
}
Include these two lines in your code. Then in Thread.CurrentPrinciple.Identity will have ur username.
|
|
|
|
|
|
After those two lines you can use this anywhere in the scope of that code.
Thread.CurrentPrincipal.Identity.Name
will give u the user name
|
|
|
|
|
Environment.UserName
If you just want to know which user started your process.
regards

Hi, yeah! Heres the problem.
Ive posted on this board before but in the Visual C++ area.
My Question is :
In my previous questions, I created a new EditBox Class Called CInitials
and changed the OnChar Message to append a '.' after each keypress.
The code for that was done like this:
void CInitials::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
//** Validate the entered character
if (isalpha(nChar) )
{
// ** Convert lower to to UPPER case
if ( islower(nCHAR) )
nChar -=32;
// ** Call the default windows procedure as
// ** the value of the nChar may have been altered
DefWindowProc(WM_CHAR, nChar,
MAKELONG(nRepCnt, nFlags));
// ** Call the default windows procedure
// ** again to add the period.
nChar = '.';
DefWindowProc(WM_CHAR, nChar,
MAKELONG(nRepCnt, nFlags));
}
// ** If the backspace key is pressed call the
// ** base class function twice to remove the period
// ** and the letter
if ( nChar == VK_BACK )
{
CEdit::OnChar(nChar,nRepCnt,nFlags);
CEdit::OnChar(nChar,nRepCnt,nFlags);
}
}
The CInitials Class was derived from the CEdit Class in Visual C++.
The question is, can this be done in C#? If yes how?
Thanks again

Is there a way to perfectly align the first part of a string on the left side of a combobox and the 2nd part to the right without using a fixed width font? Graphics.MeasureString would allow an approximation by repeatedly adding spaces in between until the string became too long but I assume there would still be some raggedness. THe problem with a fixed width font is that it would look different tham the remainder of our app.

I want to display filenames+dates in a combo box and sort by date. Is there a way to do it while keeping the dates to the right of the filenames?
|
|
|
|
|
Create a datatable and add the items to it. Then sort the datatable using a dataview and set the datasource of the combobox to the dataview.
|
|
|
|
|
I suppose that would work, but it seems like alot of hoops to be jumping through.
|
|
|
|
|
how are you adding the items to the combo box?
|
|
|
|
|
Iterating an internal datastructure (hash table of wrapped classes generated by the xsd tool), and if the neccesary conditions are met, calling combobox.Items.Add(filename).
|
|
|
|
|
It's the only (and best) way to do it.

I don't know exactly what you want to draw, but you need to draw them yourself. Have you looked into the Graphics namespace ? Basically a Graphics object contains a Bitmap and has methods for drawing on it.

Hi,
I'm quite new in the advanced GUI features of .NET . Can anybody tell me how to change the (back/fore)color of a scrollbar in a listbox? Did some research on the net but didn't really find a good answer.
Thanks
Gideon

Is this for a web based application or a windows applciation? In web based, we can use CSS style sheets to change the style of the scroll bar. In windows application, we do not have any direct means of changing the style of scrollbar. You could write a customized scroll bar that is inherited from windows scrollbar class.
Here is link for it in windows http://www.codeproject.com/vb/net/corescrollbar.asp[^]

|

|

Yes it is for a windows app. I saw the article before, but wasn't sure if there was a better/easier way to do it.
I know how to hide the vertical scrollbar, but how do I make the listbox scroll up or down programmatically?
Thanks,
Gideon
