Add a reference to the dll in your application.

Hello,
At present I am able to execute a vbscript on a remote machine.
The way i do this is that the code creates the vbscript file on the server, runs it, returns the result and then deletes the script file from the server.
The above is done by a combination of IO.WriteAlltext and
...
process.start();

Question:
How is it possible to run the script on a remote machine whithout copying the script file on the remote server. i.e. I would like to run the vbscript from the local machine?
but pointing to the remote machine so this way I will not have to write the script file to the remote machine.
Thanks

Form error massage. Has anyone seen it!

I am creating a windows form and have come across this error message, i cannot find information about how to resolve it.

Has anyone seen it before or know what to do.

The variable 'resources' is either undeclared or was never assigned

dont see how it could have happened either as 'resources' is a variable created behind the form to my knowledge

Apparently the answer is to close down the project and open it again and it works fine.

Vs just wanted to be awkward.

Sometimes rebuilding helps as well with these weird errors.

I get them a lot when using usercontrols.

gwithey15-Jul-09 2:06

15-Jul-09 2:06

Yeah that did work although there is another error:
Warning 1 Object reference not set to an instance of an object.

which appears every now and again and prevents me seeing the form in design view.

You don't happen to be using vs2005
I noticed I have it there more than in vs2008 (can't remember having it in 2008 ever actually)

When rebuilding the project its best to have the designer and maybe even the code closed.
Don't know why it happens, all I can think off is that it's a bug.

gwithey15-Jul-09 2:38

15-Jul-09 2:38

Yes it is strange.

will have to try that
Hopefully its a bug with vs and not my code.

Thanx for the help

skipping access denied folders when using GetDirectories()

V.15-Jul-09 1:02

15-Jul-09 1:02

is it an error or a warning?
Generally I see those as a warning when I did something like:

int my_int;

instead of

int my_int = 0;

it warns you in order to avoid being null when running a statement later.

hope this helps.

Hi all,

i can use something like the code below to get all the directory within a given folder.

DirectoryInfo di = new DirectoryInfo(@"C:\");
foreach (DirectoryInfo d in di.GetDirectories("*.*", SearchOption.AllDirectories))
{
Console.WriteLine(d.Name);
}

but as soon as i hit a folder i dont have access to it crashes.
is there anyway i can perform the same action but get it to skip folder i don't have access too?

Many Thanks,

Phil

use a try/catch?

use try-catch inside the loop. That is what I do.

BTW: .NET 4.0 will offer better methods to enumerate files/folders, without requiring a (possibly huge) array, so one will be able to really use the recursive mode.

That will not work. The exception will occur while executing the GetDirectories method itself and control will never go inside the try/catch.

It works for me, I am listing all files/folders of any device I choose (both XP and Vista).
If GetDirectories() and GetFiles() would not cope with inaccessible files and folders, they would be completely useless, wouldn't they?

In XP SP2, I created a folder(c:\TestFolder) and "denied" all the permissions under security tab. GetDirectories method itself will throw exception. Control never came to try/catch. See my code:

DirectoryInfo dirInfo = new DirectoryInfo(@"C:\");
foreach (DirectoryInfo dir in dirInfo.GetDirectories("*.*", SearchOption.AllDirectories)) {
  try {
  }
  catch {
  }
}

That is new to me. I'll have to investigate.
And what is your solution?

Never faced this issue, so far. If I do, I would go for Linq. May be something along the lines of this[^] approach.

If it .Net 2.0, Linq bridge[^] might save me.

AFAIK there is no such option present. You will have to write your own method to do this.

Beep() does not work

I implemented some sort of Beep functionality to my Application, but I don't hear a sound:

[DllImport("kernel32.dll")]
        public static extern bool Beep(int Frequenz, int Dauer);

        
        public static void Alarm()
        {
            for (int i = 0; i < 3; i++)
            {
                Beep(500, 1000);
                Beep(1000, 1000);
            }
        }

        
        public static void Beep()
        {
            Beep(1000, 1000);           
        }

On my testform I click a Button to test this:

private void button6_Click(object sender, EventArgs e)
        {
            //Program.testwindow();
            Program.Alarm();
        }

PC Speaker is ok, it beeps at startup. I am using Vista 64bit. Any suggestions?

Try adding a reference to the Microsoft.VisualBasic assembly and then, as if by magic, you can call:

Microsoft.VisualBasic.Interaction.Beep();

Can you tell what it is yet?

No need for the VB assembly, it's already there in System.Console class.
