Windows Service networking restrictions?

hi there,

today i realized a really strange behaviour of windows services.
i made a windows service that regularly checks some network services.
i wrote a class to perform these checks. it works perfectly when i wrap
it into a userspace program (command line).
but the same piece of code always refuses to connect when wrapped into
a windows service. is there something i have to obey when doing
network programming with windows services?
thanks,

j.

First what user account is your service running under?

Local System accounts will not have access to network resources. The easy solution is to go to the services and set the service to run under your account. Then it would have the same rights you have.

i tried my account (is in domain admin group),tried local system account (ok,now i know that this definitely doesn´t work Wink | ;)

and Domain Administrator Account, it´s all the same. now i just run the networking stuff wrapped in a commandline tool with task scheduler, but a windows service would my favourite choice...
thanks though

There is nothing in the .NET BCL to talk to the parallel port directly. You have to use a 3rd party library to do this, such as http://www.logix4u.net/[^].

You should use this library...

I can't remember what it's called. I used it some while ago for some parallel port, C# action.

Uh.... If I remember i'll post it.

Hello,

Thanks for your reply Grundyfoot, but there are a couple of concerns:

o Actually I want to learn the technique myself, so don't want to use any third party libraries...

o Even If I go for a 3rd party library, The money they ask for is beyond my budget...

Thanks for your help anyway.

You can't open a new window using asp.net, as the asp.net code is executed in the server. You have to use client script for that.

Example:

<input type="button" value="open" onclick="window.open(document.getElementById('IdOfTheTextbox'),'_blank');">

C#, Fortran and dll's

Kash23-Aug-05 22:55

23-Aug-05 22:55

Hi,
I am trying to call a Fortran dll in my simple C# example.
My Fortran bit looks like this:

'code'
subroutine sumit(x,i,r)
real , intent(in) :: x(i)
integer , intent(in) :: i
real , intent(out) :: r
!
!DEC$ATTRIBUTES STDCALL, DECORATE dllexport :: sumit
!DEC$ATTRIBUTES STDCALL, DECORATE, ALIAS:'sumit' :: sumit
!
integer :: j
r=0.0
do j=1,i
r=r+x(j)
end do
end subroutine sumit
'code'

and my C# bit looks like:

'code'
using System;
using System.Text;
using System.Runtime.InteropServices;

namespace ConsoleApplication1
{

class MyClass
{
[DllImport("Dll1.dll", EntryPoint="sumit")]
public static extern double sumit(double x,int i,double r);

public static void Main()
{
sumit(10.0,10,0.0);
}
}
}
'code'

But I get an exception error System.NullReferenceException.
I also tried to add reference but I get an error saying that the extension must be of type .dll but it is already.
Can anyone help.

hi
i did this:

in my Access db table, i've rows of data. each row have columns (i've a column representing ID number and other columns for other data). in VS, i've a textbox for the user to enter an ID number and then press OK button.

how to do this:

the pressing of OK button should retrieve the entire row of data belonging to THAT ID number keyed in and then displaying the data in a form in VS.

do i have to do anything regarding filtering, parameters or setting criteria?
can i have some sample codes/examples?

thanks very much!

You send a query to your Access Database to request the row. Something like this:

OleDbCommand cmd = new OleDbCommand(myConnection, 
    "SELECT id, dataColumn1, dataColumn2, etc FROM myTable WHERE id = ?")
cmd.Parameters.Add(id);
OleDbDataReader reader = cmd.ExecuteReader();
int id = reader.GetInt32(0);
string myValue = reaser.GetString(1); // etc.
