Problem to use System.Diagnostics.ProcessWindowStyle.Hidden.

Hich scores can be stored whereever you like, the registry, XML, a flat file. It's up to you. Any internet based stuff is going to revolve around a central server that at a minimum acts as a hub to allow players to find each other, even if traffic after that goes direct between the players.

To deploy a program, you're better off creating an installer, which also means it can enforce the need for the .NET framework.

hi i want, search in network for online computers by this code :

System.Diagnostics.Process pr = new System.Diagnostics.Process();<br />
            System.Diagnostics.ProcessStartInfo pstart = new System.Diagnostics.ProcessStartInfo("cmd.exe");<br />
            pstart.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;<br />
            pstart.UseShellExecute = false;<br />
            pstart.RedirectStandardOutput = true;<br />
            pstart.RedirectStandardInput = true;<br />
            pr.StartInfo = pstart;<br />
            pr.Start();<br />
            System.IO.StreamReader reader = pr.StandardOutput;<br />
            System.IO.StreamWriter writer = pr.StandardInput;<br />
            writer.WriteLine("net view");<br />
            writer.Close();<br />
            StringBuilder sb = new StringBuilder();<br />
<br />
            while (!reader.EndOfStream)<br />
            {<br />
                string line = reader.ReadLine();<br />
                if (line.StartsWith("\\"))<br />
                {<br />
                    line = line.Replace("\\", "");<br />
                    sb.AppendLine(line.TrimEnd(null));<br />
                }<br />
            }<br />
            this.textBox1.Text = sb.ToString();            <br />
            pr.WaitForExit();<br />
            pr.Close();

this code work correctly, but my problem is that when i set UseShellExecute property to false, this line of code :
pstart.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
does not work and cmd.exe was shown, how to solve this problem and prevent from show cmd.exe ?
thanks

AFAIK you can't. There basically are two kinds of apps:
- Windows apps, they can create and show a form, but they can not perform input/output in a
console window (such as "Command Prompt").
- console apps, they can create and show a form, and perform console input/output; when launched
inside a console (as a DOS command) they use that console; when launched outside, they create
a new console (which you can hide afterwards, but it WILL initially show no matter what).

cmd.exe is clearly a console app.

hi Luc Pattyn
in win app, when u start cmd.exe from your app, u can set input/output to your app(did u test my code ?), but my problem is not that, my problem is that how to prevent to display command prompt when i run cmd.exe with useSellExecute set to flase.
thanks

Constant table?

Y_R15-Dec-07 10:56

Greetings,

Mostly I use enumerations to specify a list of constants that are connected.

However, recently I needed to create a code that does the following:
Paint a line with a specific color that is set by the value of the bits in a variable.

The bits values are arranged in enumeration:
enum bits
{
Switch1 = 1,
Switch2 = 2,
Switch3 = 4,
switch4 = 8,
}

What is the best way to assign a color to each switch?

I thought of two ways:
---------------------------------------------
creating a dictionary and set its values in runtime:

Dictionary<bits, color=""> Bits_Colors = new Dictionary<bits, color="">;<br />
<br />
Bits_Colors.Add(switch1, Color.Red);<br />
Bits_Colors.Add(switch2, Color.Ivory);<br />
..</bits,></bits,>

But this solution because the dictionary is not constant and readonly would not help here.
-------------------------------------------------

Creating another enumeration for the colors and using thier names as params to Color.

<br />
enum BitsColors<br />
{<br />
  Red = 1,<br />
  Ivory = 2.<br />
  Blue = 4,<br />
  Green = 8<br />
}<br />
<br />
string name = Enum.GetNames(bits, (int) switch2 );   // name = Ivory.<br />
Color c = Color.MakeByName(name);

-----------------------------------------------------------

I wrote the code from my memory so it might be a little not working.

Sincerely yours
Y.R.

How about an array ? A constant array of colors, and you reference it by index, using the value that is the combination of your bit values.

Y_R15-Dec-07 20:15

Thanks for your reply.

I thought of that but there are two problems:

First, I don't think there is an easy way to make array a contant (except for basic types arrays).

Second, my bits values are not 1, 2, 3, 4... (which would fit to an array).
They are 1, 2, 4, 8, ... (Which requires some logic to be implemented in an array).

I thought of constant dictionary but I don't think there is a way to make the dictionary constant or readonly.

Sincerely yours
Y.R.

You could use attributes, but the code can be verbose and (perhaps) inefficient.

I'd stick with the readonly static Dictionary idea; wrap it in something so the code that uses it can't change it.

It strange that such a powerful language don't have this simple features.

How to load HTML file using XmlDocument class

I try to do

System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.Load(path);

but html document not considered by doc.Load method like regullar xml document since what have some unclosed tags such as an other unwell formated things(<link)>Can i actually load this html file by using System.Xml.XmlDocument() for purpose transform this HTML file into an XML file by using XSLT.

THANK

Christian Graus15-Dec-07 10:34

15-Dec-07 10:34

As you have found, not all HTML documents are XHTML. Therefore, a DOM class will not load them. An XSLT can generate non XML documents, but it cannot work with documents that are not XML to start with, you need a different solution.

HTML doesn't conform to XML standards. However XHTML does. The following text comes from the Wikipedia article for XHTML:

Whereas HTML is an application of Standard Generalized Markup Language (SGML), a very flexible markup language, XHTML is an application of XML, a more restrictive subset of SGML.

A solution to your problem would be to convert your HTML code to XHTML which can be understood by the XML parser. I'm not aware of a component that can do this. However this article[^] explains the processes involved.

string replace method

I use below code to fill the DataAdapter with a table contents, but the table name contain space such as "Table Name" I am using replace method to elemnate space from the table name to become "TableName" because when filling DataAdapter it returns an error and even with using the replace method I receive an error such "Syntax error in query. Incomplete query clause."

private void treeView1_NodeMouseDoubleClick(object sender, TreeNodeMouseClickEventArgs e)
{
DataSet1 ds = new DataSet1();
string stconn = "connection string";
OleDbConnection conn = new OleDbConnection(stconn);
string deletespace = this.treeView1.SelectedNode.Text.ToString();
string Deletespace = deletespace.Replace(" ","");
OleDbCommand command = new OleDbCommand("select * from '" + Deletespace.ToString() + "'", conn);
conn.Open();
OleDbDataAdapter Adapter = new OleDbDataAdapter();
Adapter.SelectCommand = command;
Adapter.Fill(ds, Deletespace.ToString());
}

Wow.

Why create a new string ?

ahawari09 wrote:
Deletespace.ToString()

What do you think 'ToString' does when called on a string ?

ahawari09 wrote:
("select * from '" + Deletespace.ToString() + "'", conn);

Why are you putting the table name in quotes ?

ahawari09 wrote:

Why don't you close the connection ?

I am using treeview control to display table contents and when I duble click the selected node I display a spacific table contents in a listview control, to do that I have to pass table name which is the selected node.text to the select statment then to the DataAdapter. There is one problem table names should not contain space or it will not run without an error. So I am tring to remove space from node.text.
