public string ParaTypes[20]
i got error: array size can not be specified in a variable declaration?
|
|
|
|
|
Oops, of course you can't, the array has to be specified during the initialization
Fixed the post, sorry for that (didn't have a compiler at the moment  )

Hi all,
I have an XML as following. I'm trying to read it with the following code:
DataSet cars = new DataSet();
cars.ReadXml("http://localhost/cars/newcars.xml");
All the nodes are getting properly populated into the Dataset created EXCEPT the "description" node. I can't find a way to make ReadXML (or similar method) to get the content of the description node and skip the HTML tags. I would like just treat that portion as pure text, ignoring the html content.
My question would be: How can I read an XML file which some of the nodes have HTML tags inserted? How could I avoid that the program treats the HTML tags as XML nodes>
thanks,
Juan

HTML content should be placed inside a CDATA section. So XML parsers will ignore it.

thanks! I'll work on that solution.

Hai all,
In my datagridview i have multple cells.i need values in all cell in each roe.
Suppose my dgridvw contains name and order as two fields.
my requirement is for each row i need value of cells separately
ie
i used a generic list
list<demo> myDemo=new list<demo>();
demo dm=new demo();//demo is class
for(i=0;i<tabCount;i++)
{
foreach(datagridviewrow row in dgv.rows)
{
dm.text=row.cells[0].value.tostring();
dm.order=row.cells[1].value.tostring();
}
myDemo.add(dm);
}
in first row i entered text=myText and order=1
in second row i entered text=urText and order=2
but atlast i am getting later values for each row.
ie urText and 2 in both row.
i need different values for different row
pls help me
|
|
|
|
|
i think putting myDemo.add(dm);
inside
foreach(datagridviewrow row in dgv.rows)
{
dm.text=row.cells[0].value.tostring();
dm.order=row.cells[1].value.tostring();
myDemo.add(dm);
}
may solve ur problem

what about this
foreach(datagridviewrow row in dgv.rows)
{
demo dm=new demo();
dm.text=row.cells[0].value.tostring();
dm.order=row.cells[1].value.tostring();
myDemo.add(dm);
}

There are two applications (actually it is one -server-client-). They connect each other using TCP/IP. When the client application sends restart command the server application runs cmd.exe with 'shutdown -r -f -t 0' parameters and there is no problem pc is being restarting, if pc is started with Administrator user. When we start the pc with another user not Administrator server client application runs cmd.exe the same way but it does not restarted.
A couple of things come to my mind but I don't know what and how I do, let me explaing;
1-)Do I need to set something on the pc which was done for Administrator user?
2-)or do I need to add something to parameters ('shutdown -r -f -t 0') to run the server application like 'Run as Administrator..' and I think the second comment will the key.
Many thanks.
Muharrem.

The account that runs the Shutdown command has to have the Shutdown priviledge. I take it you're trying to shutdown a Windows Server machine, which no normal user has the permissions to do. It can only be done by and Admin level account.
Instead of using the Shutdown command, you might want to change to using ExitWindowsEx[^] instead.

First of all many thanks for your help.
I changed my code like;
[DllImport("aygshell.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool ExitWindowsEx([MarshalAs(UnmanagedType.U4)]uint dwFlags, [MarshalAs(UnmanagedType.U4)]uint dwReserved);
[DllImport("aygshell.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool ExitWindowsEx([MarshalAs(UnmanagedType.U4)] ExitWindowsAction uFlags, [MarshalAs(UnmanagedType.U4)] uint dwReserved);
enum ExitWindowsAction : uint
{
EWX_LOGOFF = 0,
EWX_SHUTDOWN = 1,
EWX_REBOOT = 2,
EWX_FORCE = 4,
EWX_POWEROFF = 8
}
And I called the method
ExitWindowsEx(ExitWindowsAction.EWX_REBOOT, 0);
firstly I had an error "unable to load DLL" -0X8007007E-
and I found 'aygshell.dll' dll and copied it to C:\Windows\System32\aygshell.dll and also where my exe is.
And secondly I had an another error "An attempt was made to load a program with an incorret format" -0X8007000E-
What can I do, where is the wrong?

AYGSHELL is only available in Windows CE. Sorry, but I linked to the wrong version of the page. You're looking for this one[^].

final code is;
[Flags]
public enum ExitWindows : uint
{
// ONE of the following five:
LogOff = 0x00,
ShutDown = 0x01,
Reboot = 0x02,
PowerOff = 0x08,
RestartApps = 0x40,
// plus AT MOST ONE of the following two:
Force = 0x04,
ForceIfHung = 0x10,
}
[Flags]
enum ShutdownReason : uint
{
MajorApplication = 0x00040000,
MajorHardware = 0x00010000,
MajorLegacyApi = 0x00070000,
MajorOperatingSystem = 0x00020000,
MajorOther = 0x00000000,
MajorPower = 0x00060000,
MajorSoftware = 0x00030000,
MajorSystem = 0x00050000,
FlagUserDefined = 0x40000000,
FlagPlanned = 0x80000000
}
[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool ExitWindowsEx(ExitWindows uFlags, ShutdownReason dwReason);
And I used the method;
ExitWindowsEx(ExitWindows.LogOff, ShutdownReason.MajorOther);(LogOff) It does work there is no problem but
ExitWindowsEx(ExitWindows.Reboot, ShutdownReason.MajorOther); Reboot It doesn't work.
I think there is something about 'AdjustTokenPrivileges' on page which you've sent me, but I couldn't integrated this part of code (I don't know where I have to write this code about 'AdjustTokenPrivileges' I've written something and I will be trying)
Although the remote pc is started Administrator user the method doesn't work with Reboot parameters.
Many Thanks for all.

I couldn't cope with the ex-code and I found different code which is similar to other.
Finall code is;
[StructLayout(LayoutKind.Sequential)]
private struct LUID
{
public long dwLowPart;
public long dwHighPart;
}
[StructLayout(LayoutKind.Sequential)]

public long dwVerMinor;
public long dwBuildNumber;
public long PlatformID;
public string szCSDVersion;
}
[StructLayout(LayoutKind.Sequential)]
private struct TOKEN_PRIVILEGES
{
public long PrivilegeCount;
public LUID_AND_ATTRIBUTES laa;
}

private static extern long AdjustTokenPrivileges(long TokenHandle, long DisableAllPrivileges, TOKEN_PRIVILEGES NewState, long BufferLength, long PreviousState, long ReturnLength);
private static bool EnableShutdownPrivledges()
{
bool EnableShutdownPrivledges = true;
long hTokenHandle = 0;
long hProcessHandle = GetCurrentProcess();
if ((hProcessHandle != 0L) && (OpenProcessToken(hProcessHandle, 40L, hTokenHandle) != 0L))
{
LUID lpv_la = new LUID();
string VBS0 = null;
string VBS1 = "SeShutdownPrivilege";
if (LookupPrivilegeValue(ref VBS0, ref VBS1, lpv_la) != 0L)
{
TOKEN_PRIVILEGES token;
token.PrivilegeCount = 1L;
token.laa.udtLUID = lpv_la;
token.laa.dwAttributes = 2L;
if (AdjustTokenPrivileges(hTokenHandle, 0L, token, 0L, 0L, 0L) != 0L)
{
EnableShutdownPrivledges = true;
}
}
}
return EnableShutdownPrivledges;
}
[DllImport("user32", CharSet = CharSet.Ansi, SetLastError = true, ExactSpelling = true)]
private static extern long ExitWindowsEx(long dwOptions, long dwReserved);
[DllImport("kernel32", CharSet = CharSet.Ansi, SetLastError = true, ExactSpelling = true)]
private static extern long GetCurrentProcess();
[DllImport("kernel32", EntryPoint = "GetVersionExA", CharSet = CharSet.Ansi, SetLastError = true, ExactSpelling = true)]
private static extern long GetVersionEx(OSVERSIONINFO lpVersionInformation);
private static bool IsWinNTPlus()
{
bool IsWinNTPlus = true;
return IsWinNTPlus;
}
[DllImport("advapi32", EntryPoint = "LookupPrivilegeValueA", CharSet = CharSet.Ansi, SetLastError = true, ExactSpelling = true)]
private static extern long LookupPrivilegeValue([MarshalAs(UnmanagedType.VBByRefStr)] ref string lpSystemName, [MarshalAs(UnmanagedType.VBByRefStr)] ref string lpName, LUID lpLuid);
[DllImport("advapi32", CharSet = CharSet.Ansi, SetLastError = true, ExactSpelling = true)]
private static extern long OpenProcessToken(long ProcessHandle, long DesiredAccess, long TokenHandle);
When I use the method
long uflags = 2L; // reboot
if (EnableShutdownPrivledges() == true)
ExitWindowsEx(uflags, 0L);
else
ExitWindowsEx(uflags, 0L); // to run method in any case, but It doesn't work without
// giving privileges to a user.
The problem is to give privileges to a user When the 'LookupPrivilegeValue' runs 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt' error returns.
I think If I solve giving privileges to a user that will be ok.
Any suggestions you might have?
Thansk all Mr. Kreskowiak.

I found Sanur.exe as most of you might know that.
Start>Run>cmd
and Runas /u:domain\username "programName which you want to run" | "C:\where\Sanur.exe" password
it runs runas exe and Sanur.exe and I think sanur.exe reads the command line and sends the password and runs the program.
My question is how I can do that in .net (C# ). For example if I write;
string commandLine = "notepad.exe";
ProcessStartInfo ps = new ProcessStartInfo("cmd.exe", "/C \"" + commandLine + "\"");
ps.CreateNoWindow = true;
ps.UseShellExecute = false;
Process.Start(ps);
something like that it runs the notepad there is no problem.
So how I run an exe where is C:\xxx\123.exe using the code above.
if I set "u:domain\username "programName which you want to run" | "C:\where\Sanur.exe" password" parameter to commanLine variable it doesn't work.
How can I do that, Many thanks already.

I tried it out and it does work.
Process p = new Process();
ProcessStartInfo psi = new ProcessStartInfo("cmd.exe");
psi.Arguments = "/C \"C:\\Windows\\System32\\Runas.exe /u:domain\\username C:\\XXX\\123.exe | C:\\Sanur.exe password\"";
p.StartInfo = psi;
p.Start();

Hi,
I need to run a exe file from the local system using a web page.My attempt show error.
My code to call the exe from a web page is :-
System.Diagnostics.Process.Start
(@"D:\ProgramFile\WindowsApplication1.exe", "" + UsrId + " " + TextBox2.Text + " ");
and
System.Diagnostics.Process.Start("notepad");
It is properly working in the local system using http://localhost. When i publish the application ie. run from a site eg: http://192.169.1.26/application/login.aspx from server system, the windows form is not display.
Error message:--
"An unhandled exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll"
"Additional information: Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application."
"Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application."
This is the error message in case of opening an windows form. No message is shown when i open a notepad, its not visible.
Regards,
YPKI

Did you expect the windows form to appear in the machine where you are browsing the web page? If yes, you need to do some reading on how web applications works.
BTW, why do you want to launch some executable from a web application?
|
|
|
|

Yes, i need to appear the windows form in the machine and need to do some online works, using socket. The concept of yahoo messenger, but i need to open the .exe from a button click event from the website.

Yahoo messenger is not opened from a webpage. It is a stand-alone application which communicates with a remote server.
ypki wrote: Yes, i need to appear the windows form in the machine
Then you need the executable file on this machine. It can't be launched through a web page which resides on a remote server. As I said, you need to do some reading on how web applications works.
