Wow, what a strange error. And where did you copy it ? Can you post your code ?

[code]
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
namespace foo
{
[DllImport("user32.dll")]
public static extern int MessageBeep(int type);
public class FooFrm : System.Windows.Forms.Form
{ /* ... */ }
}
[/code]

1. don't forget about
using System.Runtime.InteropServices;
2. declare MessageBeep in your class as a method.
public class FooFrm : System.Windows.Forms.Form
{
[DllImport("user32.dll")]
public static extern int MessageBeep(int type);
}
}
3. It looks like you need more learning C#

Thanks. And this does fall under the catagory of something I've never had to do before (in any langauge). If I knew the answers I wouldn't have to post the questions.

Yes, I understand you. But still, declaring a method outside class is unknown technique to any language

I forgot c# didn't allow standalone procedures. :-/

I found it. IT won't build out of hte zipfile, and while I fixed the problem with the 2nd project not being in the solution, I can't find either dx9 reference to import. Now that I think about it, it's probably a moot point since IIRC the client for this project's running on older windows and is unlikely to have dx9 to begin with.

Could be any number of things. First, can your friend ping your IP address? Is your server application running on Windows XP SP2? Are you running any firewall software on your machine? ...

Windows XP SP2 has a firewall built into it that restricts access to the machine from the outside world. Once again, what version of XP are you running?

You had to mention that word, didn't you...
If your client software can't get through to your server, it won't make any difference what you want or how you want to do it.

I have a problem with checking file permissions. I'm trying to check wether a user can write, read to a specific folder/file but when i test my code it says it can even thou i have removed all permissions. Don't know if the code is correct.
<br />
FileIOPermission filePermission = new<br />
FileIOPermission(FileIOPermissionAccess.Write,<br />
Request.PhysicalApplicationPath+@"test\\test.txt");<br />
try<br />
{<br />
filePermission.Demand();<br />
Reponse.Write("Permission demand successful");<br />
}<br />
catch( SecurityException securityEx )<br />
{<br />
Reponse.Write(securityEx.Message);<br />
}<br />

Did you just unchecked the boxes marked Allow, or did you check the boxes marked Deny? If you just unchecked the Allow boxes, you're actually letting permissions from the parent folders to apply to the file in question. You have to explicitly deny access to the file if you wan't to take all rights away.

I have tested all things when it comes to permissions. It still says that it can write.
But it cant when actually trying to write to a file.
There something with the permission code thats wrong I just dont know what.

Hi there
I want to set a progressbar property in my user control and I don't want to be changable in runtime.
Can anyone help me?
|
|
|
|
|
Is that what you mean ?
private bool canChange = true;
private object myProp = null;
public void SetProp(object value)
{
if(canChange)
{
this.myProp = value;
this.canChange = false;
}
}
|
|
|
|
|
No
in my UserControl there is a progressbar and progressbar has a Style property and I don't want user of my usercontrol to change this property.
my userControl shuold not have this propery in its properties
|
|
|
|
|
You can just make this progressbar private,or if you need it to be public you may try :
public override myProgress.Style
{
}

I'm trying to run an example that I found in a book that is for VS 2005.
They use
"using System.Collections.Generic" (which is not there in VS 2003)
and also they use IEnumerable to provide foreach support to a class like this:
public class ClassName : IEnumerable<string>
and then
public IEnumerator<string> GetEnumerator()
{
foeach(){ }
}
I'm not able to tack on the <string> to either IEnumerable or IEnumerator in VS 2003 (to show that I'm returning a string from the foreach function) and I'm wondering if I'm missing including something or if this just cannot be done in 2003.
Thanks
