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.

Can anyone help me?

Is that what you mean ?

//UserControl
private bool canChange = true;
private object myProp = null;
public void SetProp(object value)
{
   if(canChange)
   {
      this.myProp = value;
      this.canChange = false;
   }
}

You can just make this progressbar private,or if you need it to be public you may try :

public override myProgress.Style
{
   //do nothing;
}

IEnumerable<string> in VS 2003

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

Generics are not available in .NET 1.1, so yes, you can't do it from within VS .NET 2003. You can try one of the express editions that are available for free, over here(http://lab.msdn.microsoft.com/express/vcsharp/default.aspx[^]).

While trying to write a Serial Device Comm app, I came across a class called CommBase written by Jim Hind.

I kept trying to implement it in my app but, kept getting an error about it not being reference or no directive. I then realized that the class description for CommBase was an abstract class.

So I created another class that referenced this one and it work fine. So why would anyone want to do this? I'm not quite sure I understand what an abstract class is, can anyone explain the need for this sort of thing?

Thanks

An abstract class is a class that is meant to be derived from by other classes. It is used to provide a single interface that can be implemented differently. While interfaces also provide the functionality, abstract classes allow implementation, so you can have the abstract base class provide a sort of template, with the missing parts filled in by the deriving classes.

The very first step to record audio is to use the search function of your favorite search engine.
It'll point you to lots of results, even several here on CP.

adding items to a list box using a dataset

Hello,

I have a 1 table with a list of departments, and another table with a list of employees who work in those departments.

What I want to do is select a department from a combo box, and display all the employees who work in that department in a list box.

I am using a dataset and created the data relationship between the 2 tables. My code is as follows:

OleDbCommand cmd = cnn.CreateCommand();<br />
			cmd.CommandType = CommandType.Text;<br />
			cmd.CommandText = "SELECT * FROM Employee";<br />
			da.SelectCommand = cmd;<br />
			da.FillSchema(ds,SchemaType.Source,"Employee");<br />
			da.Fill(ds,"Employee");<br />
<br />
			cmd.CommandText = "SELECT * FROM Department";<br />
			da.SelectCommand = cmd;<br />
			da.FillSchema(ds,SchemaType.Source,"Department");<br />
			da.Fill(ds,"Department");<br />
				<br />
			//Create the relationship for the employee and department tables<br />
			DataColumn parentColumn = ds.Tables["Department"].Columns["DepartmentCode"];<br />
			DataColumn childColumn = ds.Tables["Employee"].Columns["DepartmentID"];<br />
				<br />
			ds.Relations.Clear();<br />
			DataRelation drEmployees = new DataRelation("EmployeeDetails",parentColumn,childColumn);<br />
			ds.Relations.Add(drEmployees);<br />
<br />
//Use a for loop to add all the employees into a list box - have problem with this part<br />
foreach employee in departments<br />
   Add to the list box<br />

Many thanks in advance,

Steve

EnableVisualStyles on a TabPage having a problem with some controls

Joe_Huddleston13-Jun-05 4:22

Hi,

Sorry if this is obvious, but...

I'm writing a C# Forms app in VS.NET 2003. I have enabled the XP theme in the form by importing the requisite functions from uxtheme.dll and calling EnableVisualStyles().

To get the style to show on the tab pages, I implemented a paint handler for the tab pages where I call DrawThemeBackground(). (all of this I have gotten from articles here)

All of this works fine, and the tab pages themselves look great, but the problem is that labels and checkboxes on the tab pages, which I have set to use a transparent background and FlatStyle=FlatStyle.System, paint a white background.

I tried creating custom controls, where I inherit from Checkbox and Label, and override OnPaint and do something similar to what I did for the tab page, but it still doesn't work.

Any ideas as to what I'm doing wrong, or missing?

Thanks,

Joe

Yes. I had a call to DoEvents() right after calling EnableVisualStyles().

I sprinkled DoEvents() calls liberally throughout the tab page's Paint event handler, as well as in the OnPaint in my custom checkbox control, to see if there is some point in the painting that needed it, but there was no change.
