In a other word as your mean, numericUpDown control can't finish this function?
|
|
|
|
|
No, I mean the numeric control obviously contains a textbox, if there's one there. So, you need to find out how to get access to it

Use public DirectorySecurity GetAccessControl ()
for eg;
using System;
using System.IO;
using System.Security.AccessControl;
namespace FileSystemExample
{
class DirectoryExample
{
public static void Main()
{
try
{
string DirectoryName = "TestDirectory";
Console.WriteLine("Adding access control entry for " + DirectoryName);
// Add the access control entry to the directory.
AddDirectorySecurity(DirectoryName, @"MYDOMAIN\MyAccount", FileSystemRights.ReadData, AccessControlType.Allow);
Console.WriteLine("Removing access control entry from " + DirectoryName);
// Remove the access control entry from the directory.
RemoveDirectorySecurity(DirectoryName, @"MYDOMAIN\MyAccount", FileSystemRights.ReadData, AccessControlType.Allow);
Console.WriteLine("Done.");
}
catch (Exception e)
{
Console.WriteLine(e);
}
Console.ReadLine();
}
// Adds an ACL entry on the specified directory for the specified account.
public static void AddDirectorySecurity(string FileName, string Account, FileSystemRights Rights, AccessControlType ControlType)
{
// Create a new DirectoryInfo object.
DirectoryInfo dInfo = new DirectoryInfo(FileName);
// Get a DirectorySecurity object that represents the
// current security settings.
DirectorySecurity dSecurity = dInfo.GetAccessControl();
// Add the FileSystemAccessRule to the security settings.
dSecurity.AddAccessRule(new FileSystemAccessRule(Account,
Rights,
ControlType));
// Set the new access settings.
dInfo.SetAccessControl(dSecurity);
}
// Removes an ACL entry on the specified directory for the specified account.
public static void RemoveDirectorySecurity(string FileName, string Account, FileSystemRights Rights, AccessControlType ControlType)
{
// Create a new DirectoryInfo object.
DirectoryInfo dInfo = new DirectoryInfo(FileName);
// Get a DirectorySecurity object that represents the
// current security settings.
DirectorySecurity dSecurity = dInfo.GetAccessControl();
// Add the FileSystemAccessRule to the security settings.
dSecurity.RemoveAccessRule(new FileSystemAccessRule(Account,
Rights,
ControlType));
// Set the new access settings.
dInfo.SetAccessControl(dSecurity);
}
}
}
I hope this will help you

How to get information about Mp3 tag (title, artist ...)?
|
|
|
|
|
V1 tags are free text on the end of the file. V2 tags are compressed. There's some free code on the web that reads both, WMP and DirectShow will also do it.

I have not worked with Consoles before but I am trying now.
I have an app that when you type in "setproxy none" it disables the proxy. When you type "setproxy testproxy:80" it enables the proxy.
How would I execute these commands when pressing a button?
Thanks!

You don't have a button, it's a console app. But if you mean how does a windows app call a console app, Process.Start.

Call me stupid. What do you mean by Process.Start? I want to be able to execute some line of code from a windows app.

If you build a console app, you can run it with Process.Start. Isn't that what you want to do ?

Maybe you want to create a windows application and handel the click event... and just place the source code from your console application into that event handler.

Hi,
To read the XML file or string you can use the XmlDocument class which is in the System.XML namespace.
XmlDocument doc = new XmlDocument();
doc.Load("xmlstring");
doc.LoadXML("xmlfile");
XmlNode root = doc.DocumentElement;
XmlNodeList list = root.ChildNodes;
foreach(XmlNode node in list)
{
if(node.HasChildNodes)
{
XmlNodeList list1 = node.ChildNodes;
foreach(....)
{
}
}
else
{
string name=node.Name;
string text=node.InnerText;
}
}
Hope this code helps you.

You would use XmlDocument, but you'd use XPath to go direct to your node, as in
foreach(XmlNode node in doc.SelectNodes("//deatails/phone_no/No"))
And to do this, you'd fix your schema and replace No1, No2 and No3 with nodes that all have the same name ( and a number as an attribute if you need it for number, but the order will never change anyhow ).

hi ,
thanks for giving helpful idea.
i try that but in, i can't get the data of node
plz check my code give any modifications.
iam new to c#.net and xml
private void button1_Click(object sender, System.EventArgs e)
{
string filename = "C:\\C#program\\cs_programs\\singlenode\\bin\\Debug\\nodexml.xml";
XmlTextReader tr = new XmlTextReader(filename);
XmlDocument doc = new XmlDocument();
while(tr.Read())
{
foreach(XmlNode node in doc.SelectNodes("//details/add/addr"))
listBox1.Items.Add(doc.Value);
}
}
|
|
|
|
|
Like I said, your schema is useless. You need to change the addr1/addr2/addr3 nodes to all be just addr. And don't forget, XML is case sensitive.

hi Christian
i new to c#.net
i want to access one node in xmlfile using c#.net .
that node have child node (i want that child node values)
i write my xml file like this
<
<<name>
<<n>Ap
<<n>MP
<<n>UP
<
<<add <<addr1="">gjsefgjkl<<addr2>dfhtyxcvd<<addr3>ioiopweri
<
in this i want to access the "add" child node value.
i wrote c#.net code like this,
"When i press Button the childnode("add") values r stored in listbox "
plz change any modification in my code or plz give code how to access thatnode
private void button1_Click(object sender, System.EventArgs e)
{
string filename = "C:\\C#program\\cs_programs\\singlenode\\bin\\Debug\\nodexml.xml";
XmlTextReader tr = new XmlTextReader(filename);
XmlDocument doc = new XmlDocument();
while(tr.Read())
{
foreach(XmlNode node in doc.SelectNodes("//details/add/addr"))
listBox1.Items.Add(tr.Value);
}
}
Thanks

Well, if you want to access the add node, just drop the rest of the XPath - /details/add
If you want to get all the addr nodes, name them all addr, as I advised you to do in the first place.

Hi. I have written a code that has no recursive function in Visual Studio.NET 2003(C#). It personalize a smart card. After it personalize some cards(24 for one system, 60 for the other, 18 for another), it ends with a stackoverflow exception. I use WndProc in my project. When the unhandled exception occurs, it breaks in the end of WndProc. How can I find when this error occurs and how can I solve this error?
Thanks in advance

your program is recursive in some way, which is causing the problem. It doesn't have to be a single method that is recursive, it might be methods that call each other in turn.
The only time the stack usage changes is when you call a method, and when you return from the method the stack usage returns to the previous state. That concludes that the only way to get a stack overflow in the way that you do is to call methods that you never return from.
