Even with that error fixed the code you have posted wont do what you want.
so here are the fixes, the should work...
1. in you load event change the 'families' to 'fonts'
2. just before you foreach loop add the following line...
comboBox1.Items.Clear();
3. inside your foreach loop replace all code with this line only...
comboBox1.Items.Add(family.Name);
this should then populate you combo box with all the fonts
4. in your selected index changed event add the following code to alter you textbox font...
textbox1.Font = new Font(comboBox1.Text, 10);

I get a error:
foreach statement cannot operate on variables of type 'System.Drawing.Text.InstalledFontCollection' because <'System.Drawing.Text.InstalledFontCollection' does not contain a public definition for 'GetEnumerator' ...................................
Thats after foreach (FontFamily family in fonts) - changing it from 'family' to 'fonts'
This is so much harder than small basic but i like challenges, ones that not go so well

Change the foreach from fonts to fonts.Families

Whoops. I took the code from one of my snippets, so had to adapt it for some reason. Don't worry though, I'm not annoyed in the slightest. You're trying to learn, and that's always a good thing

Have you tried FontDialog? I dont know if its useful for u:
using System.Windows.Forms;
FontDialog fontDialog = new FontDialog();
if ( fontDialog.ShowDialog() != DialogResult.Cancel )
{
textBox.Font = fontDialog.Font;
}

Hi,
I have built a class called MyGlobal with a name space of nsMyGlobal. I have added the .DLL to the references and I can see MyGlobal in the list.
I then add a "using MyGlobal;" to the top of my new project C# source and then added a:
myglobal = new MyGlobal( ); // define a reference to it
When I try to build, I'm getting the following error message:
Error 1 The type or namespace name 'MyGlobal' could not be found (are you missing a using directive or an assembly reference?)
I'm not sure what I did wrong...
Thank you,
Glenn

See the error now?
No? Try
using nsMyGlobal;

You say your namespace is 'nsMyGlobal', so is it not...
nsMyGlobal.MyGlobal myglobal = new nsMyGlobal.MyGlobal();
Of course, with that you dont need the 'using' statement, which should be 'using nsMyGlobal;' anyway

Hi,
I'm looking for a way to get a hex string into an integer without converting it. IE: The user enters 10, if I use "uint32 x = Convert.UInt32(String)" I end up with 0x0A, not 0x10. I know if I use a pointer and do it by byte at a time it will work, but I was looking for something a little more straight forward.
Thanks,
Glenn

Hi,
uint.Parse(string, NumberStyles.HexNumber) translates "10" into sixteen.

how about...
int x = int.Parse("10", System.Globalization.NumberStyles.HexNumber);

Hello fellas! i'm trying to built an implementation of user session which timeout after a certain pediod. I have a class usersession which does the job.
<pre>using System.Timers;
public class usersession
{
private static bool sessionalive;
private static Timer usertimer;
public static bool SessionAlive
{
get { return sessionalive; }
set { sessionalive = value; }
}
public static void BeginTimer()
{
try
{
SessionAlive = true;
//usertimer.Start();
usertimer = new Timer(int.Parse(ConfigurationManager.AppSettings["sessiontime"].ToString()));
usertimer.Enabled = true;
usertimer.AutoReset = false;
usertimer.Elapsed += new ElapsedEventHandler(DisposeSession);
}
catch (Exception ex)
{
return;
}
}
private static void DisposeSession(object source, ElapsedEventArgs e)
{
try
{
SessionAlive = false;
}
catch (System.Exception ex)
{
return;
}
}
public static void ResetTimer()
{
try
{
SessionAlive = true;
usertimer.Stop();
usertimer.Start();
}
catch (Exception ex)
{
return;
}
}
}
</pre>
as you can see begintimer function set the property SessioAlive to true and then instantiate the timer.when that time arrives the disposesession fires and set the property to false.on my main form the constructor calls the begintimer function through startsession function <code>public frMain()
{
InitializeComponent();
StartSession();
//SessionChecker();
}
public void StartSession()
{
try
{
usersession.BeginTimer();
}
catch (System.Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
</code>
so any time the user click on something, i check the usersession.SessioAlive property like so inside this switch case snippet
<code>case "transfer":
if (!usersession.SessionAlive)
{
new LoginForm().ShowDialog();
}
MessageBox.Show("cash back transfert page");
break;
</code>
and inside the loginForm if login is correct we call the usersession.ResetTimer() and resettimer set SessionAlive property to true then the user can work again until there is no activity until session expores again.
<code>
this.DialogResult = DialogResult.OK;
usersession.ResetTimer();
this.Close();
</code>
It's working just fine.Now i really wanted the checking to be run in background(the commented sessionchecker on the main form) that's were i need your advice.here i use forms.timer on the main form to create a small job but since forms.timer doesn't have autoreset it doing an endless loop by calling the loginform and i have to stop the process from the task manager.
<pre>
private void SessionChecker()
{
try
{
check = new Timer();
check.Enabled = true;
check.Interval = 1000;
check.Tick += new EventHandler(check_Tick);
}
catch (Exception)
{
throw;
}
}
void check_Tick(object sender, EventArgs e)
{
try
{
if (!usersession.SessionAlive)
{
new LoginForm().ShowDialog();
check.Stop();
}
}
catch (System.Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
</pre>
How to make the cheking being run in the background and when session expires block the application by asking credentials?I can't really see the mistake i'm doing.But since it's not working as expected i'm doing something wrong.Can you help me solve this?Thanks for reading
eager to learn

Hi there,
Although your idea is not bad, i find it a rather strange way of doing an expired session...
what i would do ( although i am no coding god either so feel free to correct me)
For example you want your session to be valid for 15 Minutes:
You simply make a Session variable like:
session.Item("expirationtime") = DateTime.Now().AddMinutes(15)
then, on every call you make that is < session.Item("expirationtime") , you set this again
if(session.item("expirationtime") < DateTime.Now())
{
}
Seems a hell of a lot simpler and has better performance then spinning of threads to keep timers ticking.. (500 visitors logged in means 500 threads running a timer)
Do Or Don't, there is no "try catch ex as exception end try"
